Safety and health -- -- -- -- -- -- -- -- the noise

Noise is harmful body health,noise can interfere with the work efficiency,first of all, a distraction,especially influence or highly skilled work hard work,it also hinder the communication and warning signs,cause an accident.

Especially:noise is harmful to the operator's hearing,the sudden outbreak of high noise,which can lead to staff temporary hearing loss for a few days.
Often exposed to high noise environment,can lead to inner ear tissue damage and persistently,incurable hearing loss.
No cover near the diesel generator set noise level over from the factory standards,the operator work beside the diesel generator set,should be put on the sound insulation cover ears,in work clothes.
If the engine is equipped with sound insulation of diesel generator set equipment,then both can prevent indoor voice to the outside,and can prevent the outside of the incoming sound.But work near the generator insulation workers must wear earmuffs.
Here are several kinds of the methods:
1.The need to wear soundproof earmuffs marks.
2.Within the scope of protection,the need to control the non-working personnel to enter.
3.To ensure that provide and use qualified sound insulation earmuffs.
4.The operator work,pay attention to protect the hearing.

Diesel generator fuel tank installation rules

1.Tank location must be safety to prevent fire, tank or oil drums shall be separately in a visible place, properly away from generators, smoking is not allowed and strict rules.
2. The tank filled with fuel should ensure the daily supply capacity.
3. After the tank is placed, the highest oil level can't its 2.5 m higher than the base unit, such as large oil depot oil level is higher than 2.5 m, should add day tank between large oil depot and the unit, the direct oil pressure is not more than 2.5 meters. In time during the period of diesel engine is shut down, do not allow the fuel rely on gravity, through the inlet pipe or hose into the diesel engine.
4. Used oil mouth does not allow more than the resistance of the regulations on diesel engine performance data sheet using clean filter when the specified value. The resistance value is based on half of fuel on the basis of the fuel tank.
5. Fuel oil resistance path cannot be more than the data the provisions on the list.
6. The fuel return hose connection should not cause tubing fuel in shock wave.

Diesel generator maintenance matters needing attention.

Diesel generator maintenance project has a lot of,also has a lot of the same need to be aware of items,let us take a look at what need to pay attention to below:
1.the radian of carbon brush must conform to the surface of  the collector ring,otherwise shall be grinding.
2.main parts,such as rotor,end cover,base,collector ring and brush set,etc.,must be light to avoid deformation due to the impact.
3.remove the container parts must be properly kept,don't stay lost nor any behind.
4.remove the bearing,bearing and the bearing cover parts must be completed to cover with a clean paper.Don't make the dust fly.On such as dust,grease all must be changed.
5.the motor installed,gently rotating the rotor by hand,and check for friction sound,or rotation is not flexible.
6.removed the thrum,should mark,should be according to the original position by connected to reinstall,absolutely not wrong.
All landowners end cover screw and the screw pole must be a number of cross screwing in at the same time,can't close a first,and then the other.

Diesel engine to choose factor to consider.

1.the use of diesel generator.For frequent starting and often moving machinery,such as tractors,agricultural vehicles,mobile power station,etc.,can choose light high speed diesel engine;For fixed power plant,such as agricultural irrigation and drainage,agricultural and sideline products processing machinery supporting power,you can choose rotational speed is low and the potentiality of diesel engine.At the same time,for agricultural power,most of the long-term continuous operation,so the good economy is very important.
2.the service life of diesel engine and working reliability Due to poor rural use and maintenance condition,should choose to long-term reliable operation of diesel engine,and cannot be divorced from reality,pure pursuit of indicators advanced.
3.want to consider to diesel engines"seriation,standardization,generalization"level."Three"high degree of diesel engine replacement gm parts and repair is very conveninet,and parts supply is adequate,so try to choose products.
4.Due to factors such as wear and tear of the parts,in the long-term operation of diesel engine power and fuel economy will gradually reduce,so in the form a complete set if diesel engine power to the appropriate scope,in order to make full use of its benefits.Plateau areas should also be considered due to high altitude,low atmospheric pressure and cause of the decline of the power.

The causes of diesel generating sets fault.

The concept of failure,for just the factory of diesel generator set,it must have certain work ability and durability of the necessary work ability refers to the design and manufacture technology gives the diesel generator set main job performance,such as the output power of diesel generator set,engine fuel consumption and noise level of unit,such as durability refers to the unit to maintain the ability to work within a certain range of the use of time,the working ability of the diesel generator set also durability deterioration,is fundamental to the malfunction sign,that is ,all parts of the diesel generator set technical status,change in working time regret,when this kind of change is beyond the permitted scope of technology,and affect the performance of the generator set,is has the fault on the diesel generator set,fault have greatly small,according to the actual situation to guarantee.Thus huaquan power electrical and mechanical equipment installation debugging personal training system and actual combat.Targeted treatment of diesel generator sets troubleshooting.

Generator power reduction reason analysis

From the working process of diesel engine already know,mixes with hot air burning diesel injection cylinder combustion and power generation.So size of the diesel engine horsepower naturally and air quantity and the amount of diesel fuel burns.At high altitudes,due to the atmospheric pressure drop,air density decreases,and air in the intake valve weight also reduce accordingly,which limits the amount of diesel fuel to burn,horsepower will decline.For the same reason,the air of high temperature,high humidity can also reduce the power of diesel engine.So, in different regions,or in the same area using diesel engine under different atmospheric conditions to consider the power change.For example,summer can send the same diesel engine power than lower in winter.Diesel generator set work,many parts under certain load relative sliding or rotating at high speed,such as the piston and cylinder liner,crankshaft and bearing,etc.The surface of the parts while there are different levels of lubrication,but with the increase of working time,mutual contact surface is due to the friction and wear,undermine the original size and geometry shape.The normal wear and tear is often referred to as "wear and tear",actually is inevitable.But this is not to say,we are powerless to wearing away,listen to the nature.In fact through the correct choice to cooperate with each other parts of the material,the use of advanced and reasonable heat treatment meth,the improvement of contact surface parts processing quality and cooperate with the condition,improve cooling and lubrication,timely maintenance to take active measure,this will significantly reduce the wear and tear,and thus improve the working reliability of diesel engine,prolong service life.

Conform to the characteristics of diesel generator set

Load characteristics of diesel generator set, this practice is the load characteristics of synchronous generator because it is directly at the load.Has been expounded in synchronous generator work sense: rotor winding dc current going into the tamper with the rectifier supply, in the building in the air gap between the stator and a magnetic field, as the rotor magnetic field or the main magnetic field.Then connect the armature winding of the stator or call a load, also because of the load current flows through the building have a magnetic field in air gap, called a stator and armature magnetic field.This two magnetic field in air gap naturally together form a composite magnetic field.The size of the synchronous generator output voltage and current is by its resolution.

Caused the main reason for the synthesis of magnetic field change is the armature magnetic field due to the different nature of load change.This as the armature reaction: when the armature winding of generator;Reason is a who on inductance coil, only a pure resistive load, winding voltage and current in phase, the armature magnetic field and the rotor magnetic field superposition, what to synthesize magnetic field without replacement.Only bring generator load operation, the stator flux to be in a saturated form to absorb some of the armature magnetic field, and make the synthesis of magnetic field is slightly reduced.The more the greater the load current is reduced.
If the armature winding is only pure inductive load, the armature current potential to lag phase Angle of 90 degrees.Created by the current of the armature magnetic field on the rotor magnetic field cancellation in formation, so that the synthetic field weakening and distortion.The output of the generator voltage and reduced.
Assuming that only the pure capacitive load to the armature winding, then due to the nature of the capacitance, makes the armature winding current phase Angle of 90 degrees in advance than its potential.The current form of the armature magnetic field or strengthen the rotor magnetic field, which makes synthetic magnetic field is strengthened, the generator output voltage for high.
Do more than appreciation: three straight not qualitative load makes synchronous generator create born different armature reaction, then make its output voltage make replacement.Navigate these rules, or configure a better load for the diesel generator set, the unit to play all power, supply the superior power.

The definition and application of generator.

Electric Generator  is to turn mechanical energy into electrical energy motor, usually driven by steam turbine, turbine, or internal combustion engine Generator points of two kinds of dc generators and alternator, which in turn can be divided into synchronous Generator and induction Generator.Modern power plant is the most commonly used in synchronous generator (i.e., the speed of the generator rotor and the stator magnetic field rotation speed keep synchronous speed).It is composed of dc excitation current, can not only provide active power, also can provide reactive power, can meet the needs of all kinds of load.Not have independent excitation winding induction generator, its structure is simple, easy to operate, but it can't provide reactive power to the load
Therefore, run time asynchronous generator must be with other synchronous generators in parallel, or and a number of capacitor.A commutator dc generator, the structure is complex, expensive, easily out of order, maintenance difficulties, efficiency and alternator.Therefore, since the 1950 s, the dc generator gradually for the ac power by power semiconductor rectifier dc replaced.

The five points for attention during the maintenance of diesel generator

Diesel generator set maintenance is very important,and when the diesel generator set maintenance must first pay attention to safety.The stand or fall of the diesel generator set maintenance will directly affect the service life of the diesel generator set.So i want to say diesel generator maintenance considerations

1.When the maintenance personal in the maintenance of diesel engine,diesel generator for removal and installation of the parts,must be strict requirements,comply with the operational procedures,prohibit disorderly upset knock,such as screw bolt to sequentially and fastening several times,when screw without order,in case the part deformation..

2.Parts assembly before,must be clean,fight with impurities,mixed with tiny sundry,not only will leak,also directly affect the work of the engine.

3.in asbestos pad,paper pad and all kings of screw oil leak onto asbestos.To thin uniform when asbestos with oil,not too thick,also do not put the cushion on the whole face,just daub oil locally.

4.The combination of parts grinding or milling surface,its role is to restore the surface roughness and precision of joint of tubing or gasket after grinding,can maintain seal,do not leak.

5.Tightness of the sealing device is appropriate,not too tight or too loose,such as diesel engine,such as various kinds of contact surface and seal nut,must maintain appropriate tightness.

No matter good or bad, you have no way to retreat.

As a just step into the workplace soon a new person, do not have any work experience, for the job I did not understand what looks like a child, need you to teach him little by little.My company is a professional manufacturer of diesel generator set. Didn't know what diesel generating sets, holding a try attitude began my career.
Now I have been working for two months, came to the first day of the scene also scenes appear in front of my eyes, is the first day in a boring and in product knowledge, I had no one to talk, no one I, everyone is busy with their work, and finally wait until to go off work, although there is a bus company, but don't know how to go home.At this moment, my heart is the collapse and helpless, but have a zeal of colleagues to help me.
After two months of learning slowly, the relationship between the colleague is also becoming more and more close, product knowledge is also more and more understanding.But do things go smoothly is often not good.Recently, I have a customer wants to purchase our Jamaica diesel generating sets, since began to negotiate, is in accordance with the said in his heart to it, but when is close to signing a contract, but because of the transportation time, no matter how much I email don't reply to me.I'm very glad to so lucky can strike a order during the internship, however, often runs counter to reality and ideal is.Because I too want to reach an order, and now become a bubble, my mood is like rain, always not happy.
I think I should not be the case, the customer is not just only this one, maybe after slowly precipitation, there will be better.No matter good or bad, you should look ahead.

The causes of deficiency of generator output power.

The main reasons of the lack of diesel generator output power are:diesel filter clogging;diesel engine value closed lax;diesel engine nozzle atomizing bad;diesel engine piston ring and cylinder liner wear.

Generator output power is less than general power failure,the generator parts usually won't appear in this situation,common fault is generator,no voltage.High voltage,voltage establish failure load voltage when a certain amount.So when the above problems should be how to deal with?

First,between the generator and excitation reactor connected to a three phase voltage regulator,in order to improve the voltage of the generator,the excitation device of magnetic potential was gradually increase.And then change the magnetomotive force excitation device voltage and the phase of the voltage of the generator,make synthetic total magnetomotive force increase.Reduce the rheostat value,make the generator excitation current increases.
In addition to the above,such as lack of diesel engine oil,diesel oil filter clogging,diesel fuel injection pump fault can also lead to insufficient motor power output.Therefore,must pay attention to the daily and maintenance of motor,prevent the occurrence of such problems.

How to do a good job in diesel generator room sound engineering

We all know that the design of the diesel generator room is very important,because will directly affect the service life of the diesel generator set and fault occurrences.
Sound insulation:1.into the wind system in the plane into the wind set sound attenuation trough and sound barriers,the forced ventilation ways the fresh air needed for the normal operation of the unit.
2.the sound insulation of the exhaust system.Set the sound attention trough and sound barriers on surface of the exhaust air,forced ventilation,reduce the generator working environment temperature to the largest extent.
3.computer room in and out of the channel noise:in line with convenient transfer into,v and principles of computer room personal work convenient to set up one or two sound insulation door metal framework,with high quality sound insulation materials,thickness of 8 cm to 12 cm as appropriate.
4.sound-absorbing wall and sound-absorbing ceiling,chuck box installed in the computer room sound material,in order to prevent the noise coming from machine room roof and spring back,reduce the room noise decibels.
Sound system:5.flue pipe outside room is installed on the secondary damping type sound to cry,to reduce the engine exhaust noise,and don't affect emissions at the same time.

Diesel generator set right down operation

Diesel generator set operating process in the operation of the unit into the run at full speed,the generator voltage,frequency stability,normal operator power generation can be opening and closing.
Units in operation,the operator should also often see units is normal operation,the control panel meter indicates whether in party position,control panel for forecasting warning instructions,fuel situation for running parameters,and timing unit operation parameters for record.
Diesel generator set of stop operation and operator found that serious fault or power distribution unit in the failure,can press the control panel urgent stop button,to immediately stop the unit.No special circumstances occur,the user is not recommended at random by abrupt stop button to stop operating unit.
Diesel generator set normal process downtime.Before normal stop is,first of all,separate the load,then the unit running light after a certain period of time,let the unit fully cooled down for part the unit stop valve was installed,want to shut off the switch to use the unit to shop the operation of the control panel in invalid.The right stop operation,must be in control panel to electricity,press stop button to make the unit stop running.

The basic knowledge of gas turbine generator

Small conventional gas turbine generator is a typical representative of the large power generation equipment,can provide from 1 to several megawatts of power,can satisfy almost everything including office buildings,hospitals,schools,shops,the demand of the building.

Turbine generator of exhaust gas is an ideal heat source, absorption refrigerating machine is used for cooling, heating and provide sanitary hot water.Because compared with coal gas, the waste gas impurities and sulfur content is low, the second most significant is its high oxygen content, can reach more than 15% and can be used as the combustion air, direct-fired machine on the second combustion. 

Gas turbine generators are often used as power rush when load in summer.However, because of the high summer temperatures, resulting in the output of the gas turbine severity shortage, low efficiency.Therefore, lithium bromide refrigerating machine by using turbine exhaust cooling to cool air inlet of turbine generator, can greatly improve the output and efficiency of turbine generator.Has been proved to be a very effective way of energy saving. 
Turbine generator usually consists of turbine, gearbox, generator, air intake supercharger and exhaust system.
Turbine generator system according to its process is different, divided into: combined cycle, simple loop and front circulation.Combined cycle is usually produced by recycling waste heat boiler gas turbine exhaust steam, and then drive a steam turbine, or directly provide steam, is a common process of new power plants.

About the classification of the gas generator

Gas generator sets are divided into two kinds,one kinds is combined cycle gas turbine,one is gas internal combustion engine.Gas turbine power is large,mainly used in large and medium-sized power stations,gas internal combustion engine power is small,mainly used in small distributed power plants.It is a new kind of green environmental protection to replace fuel,coal-fired units.Make full use of all kinds of the natural gas or harmful gas as a fuel,into safe and convenient operation,high cost efficiency,low pollution emission,and is suitable for hot,the electric power plant,etc.
Natural gas resources in china is very rich,relative to the our country is rich in natural gas reserves,gas proportion of primary energy consumption in our country in our country is too small,has greatly increased the potential in the future.

Air quality is good or bad effects on diesel generators.

We humans need a breath of fresh air to maintain a healthy,likewise,diesel generator set also need clean air.The air contains impurities will not only harm people's health,too much failure damage can also be diesel generating set.Air quality and circulation of diesel generator set plays a decisive role,we must attach importance to in the process of using.
If the diesel generating set is used in indoor,we make sure he has plenty of fresh air.Seal if the room is too tight,it will lead to air circulation,this not only affect the diesel engine of diesel combustion rate at the same time also reduces the cooling effect of inlet air cooling can not reach,the heat generated by the unit out,room temperature will gradually rise,red alert value caused by faults,generally do not install the window,so the room with a burglar mesh instead of glass,and the height of the window above the ground is unfavorable and exorbitant,this may also affect diesel generating sets"breath of fresh air".Some customers in the outdoor use diesel generating set without considering the environment factors,just use.Gradually found that diesel engine power falling slowly,but I don't know why.In fact this is the diesel generator set a lot of dirty air inhaled or inhalation of dust and has led to the decrease of the power of diesel engine,generator if inhaled dirt magazine makes the stator gap between insulation damage,serious can lead to the generator destroyed that the environment quality,or take the necessary protective measures to "filter"air.

How to make the diesel generating set is more economical diesel

Do the following,can be very good save diesel.

1.Improve the diesel generator cooling water temperature.Water temperature increase can make diesel fuel more complete combustion,and the oil viscosity is small,can reduce motion resistance,can achieve fuel-efficient effect.

2.Change the big horse car,appropriate increase diesel engine pulley,under the condition of the diesel engine running speed down the speed of the pump, increase the capacity and head,achieve energy saving purpose.

3.Ensure that machines do not leak.Diesel generator pipeline due to the joint surface uneven,often loopholes in gasket surface deformation or damage to the phenomenon.Processing methods is,put the gasket with the value paint on the glass plate smooth,is the tubing connection.Add diesel oil recycling equipment,available plastic pipe will choke on the back of tubing and hollow screw connection,make the oil into the tank.

4.Oil purification in before.

The fault of diesel engine,more than half from the oil system.Processing method is to buy back the diesel for precipitation 2-4 days to use,can precipitate 98% impurities,such as buy now with now,two layers of silk can be put in the tanj of oil filter or toilet paper.

5.Maintain the best Angle of oil supply.Such as oil supply Angle deviation,will cause the delivery time is too late,to a huge increase in fuel consumption.

6.Adjust the injection pressure of injector.

These experiences are working in the diesel generator industry provide by the technical staff for many years,but this is just in the diesel generator set on the premise of no fault,if your diesel generator fuel more case to check whether there is fault.I hope my advice can help to you.I wish you all have a good mood everyday.

Cummins series generator working conditions.

Cummins diesel generators, I think we may not be unfamiliar, but worked for cummins diesel generator operating conditions may be not very familiar with.
1.Cummins diesel  generator can be used continuously every day,and it bearing the design concept of putting quality as first in mind,Cummins improves the average overhaul interval up to more than 30000 hours.
2.Application area:widely used for shop,hospital,high-way,station,construction,farm,etc.
3.Maintenance:it should be maintenance after running about 30000 hours;and it will reduce the fault rate and extend the lifetime of the unit.
4.Above suggestions are based on our experience and are intended only as reference.

Novice in buy diesel generator should pay attention to the details

For a diesel generator doorways,deep in buying large machinery,diesel generators that we first must understand the first industry is how to choose and buy diesel generator,what are the key points in the novice needs to be aware of when buying diesel generator?
1.The seller told the brand of diesel generator,don't offer the origin of diesel generator.
For example the United States cummins, Volvo, in fact, no one diesel generator may be performed by a company independent. New unit should be a comprehensive understanding of the diesel engine, generator, control cabinet manufacturers and brands, to comprehensive assessment of the level of the unit.
2.Diesel engine power  is as large as the generator power is configured to, in order to reduce the cost.
In fact, the general provisions of diesel engine power generator power 10% or higher, because there are mechanical wear and tear. More bad, and the diesel engine horsepower as kw false positives to the user, and with less than diesel generator power allocation unit, commonly known as: small horse-drawn cart, unit and reduced life spans, frequent maintenance the fee is high.
3, Not rated power and backup power relations, said only a "power", the backup power as a power rating to sell to customers.

In fact, the backup power = 1.1 x prime power. Moreover, backup power can only use 1 hour in 12 hours continuous running.

4, The relationship between confusion KW and KVA.

Sell KVA as KW to exaggerate the power, to the customer. In fact KVA is apparent power, KW is the effective power, the relationship between them is 1 KVA = 0.8 KW. Import units generally expressed in KVA power unit, and domestic electricity equipment is generally expressed in KW, so accounting power should be the KVA 8 discount when converted to KW.

5,Will not take protection function (commonly known as the four protection) unit as a complete protection function of units sold to customers.

What's more, the instrument is not complete, with no air switch unit sales to the customer. In fact, the general provisions of above 10 kw unit must take the whole instrument (commonly known as the five tables) and air switch; Large units and automation units must contain the four protection function.

6, Don't talk about random accessories.

With or without silencer, oil tank, oil pipe, for example, take what class battery, how much capacity battery, battery and so on. In fact, it is very important to these attachments, must be stated in the contract. What is more even without a radiator fan, let the customer since the open pool.

7, Insisting that the price and delivery time.

Don't talk about brand grade of the diesel engine and generator, control system configuration, don't talk about after-sales service, only talk about the price and delivery time. There will also be the power station for oil machine, such as: Marine diesel engine, automotive diesel engine for generator set. The end products of generating units - electric (voltage and frequency) to ensure quality. Too low price units generally have problems, commonly known as: only buy the wrong not to sell wrong!

8, second-hand refurbished machine.

Sell used a refurbished machine as a new machine to the customer, and will be renovated with new diesel engine generator and control cabinet, make general non-specialist user root can't distinguish whether new or old machine.
All in all, a novice when buying diesel generator should be careful to ask, do not rush the introduction to listen to the somebody else but to buy, before you buy diesel generator will be known to the above several ways.

Judging correctly the electric control system of diesel generating sets fault.

The parts of electric control system of diesel generator sets of performance is good or bad,electric wiring is normal or not,often with its parameters such as voltage or resistance.Without these data,the system will be difficult fault detection,tend to take a new replacement method,these methods can sometimes cause maintenance costs soared and takes work.Future use first to the type in the overhaul of the unit,should be ready to repair the unit type of the maintenance data concerned.In addition to the maintenance data,another effective way is to use trouble-free unit to measure the related parameters of the system ,and record down,as in the future maintenance of same type unit testing parameters.If notice at ordinary times,to do the job well can bring convenience to system fault check.

Special note: diesel generating sets failure is not necessarily in the motor control system. If you find malfunction with the generating set and the fault warning light is not bright, in most cases, the fault inspection according to the basic diagnostic procedures. Otherwise, you may encounter a has nothing to do with the electronic control system fault originally, but check the electric control system, such as sensors, actuators and circuit, spend a lot of time, but the real fault is not found.

Should pay attention to when using diesel generator maintenance machines, regularly check the fault of diesel generator can produce place, try to reduce diesel generator failure caused by the unnecessary trouble. I also hope that I broke the news of the diesel generator fault diagnosis can help to you.

Air quality is good or bad effects on diesel generators.

We humans need a breath of fresh air to maintain a healthy,likewise,diesel generator set also need clean air.The air contains impurities will not only harm people's health,too much failure damage can also be for diesel generator set.Air quality and circulation of diesel generator set plays a decisive role,we must attach importance to in the process of using, weifang huaquan power machinery co.,LTD.technical support and after-sales team is a leading industry,have other questions please feel free to ask us.If the diesel generating set is used in indoor,we make sure he has plenty of fresh air.Seal if the room is too tight,it will lead to air circulation,this not only affect the diesel engine of diesel combustion rate at the same time also reduces the cooling effect of inlet air cooling can not reach,the heat generated by the unit out,room temperature will gradually rise,red alert value caused by faults,generally do not install the window,so the room with a burglar mesh instead of glass,and the height of the window above the ground is unfavorable and exorbitant, this may also affect diesel generating sets "breath of fresh air. Some customers in the outdoor use diesel generating set without considering the environment factors, just use. Gradually found that diesel engine power falling slowly, but I don't know why. In fact this is the diesel generator set a lot of dirty air inhaled or inhalation of dust and has led to the decrease of the power of diesel engine, generator if inhaled dirt magazine makes the stator gap between insulation damage, serious can lead to the generator destroyed. Therefore, in the outdoor use diesel generator unit must ensure that the environment quality, price of generator, or take the necessary protective measures to "filter" air.

Air-cooled diesel engine maintenance points.
