Details of diesel generator set start and stop the two forms

Diesel genset professional information is introduced
First, the manual commissioning
1. The diesel generator set manually start: first test alarm system after normal, price controls open concern the position in the manual (MAN), diesel generating sets can be started on its own.
Parking: 2. The diesel generator set control open concern to stop (stop) position or press the red emergency stop button to stop a generator.An emergency press the emergency stop button can be directly forced outage.If press the red emergency stop button must be returned in situ, or generating set will not be able to start.
Second, automatic switching device.
1. Will open concern to automatic control (AUTO), and cooperate with the power automatic transfer switch (ATS) control switch should be used in the automatic position, when mains power outages, ATS will start signal generator control system, the opportunity to start my own to generate electricity.
2. When the control concerns to STOP (STOP), or remain in the automatic, but the utility has returned to ATS that sent the signal, the parking diesel generator set will STOP automatically.Note: the running of the diesel generator set, due to the fault (speed, high temperature, low oil pressure, etc.) and automatic stop when generating set in fault reset button after troubleshooting should be the pressure can be ready to start again.

With the correct selection of the diesel generator

With the correct selection of the diesel genset.
Diesel combustion performance mainly cetane number.The higher cetane number, the better the performance of diesel combustion, but its solidifying point is higher also.Said solidifying point diesel low temperature fluidity, refers to the oil in the cold start, the highest temperature solidification and loss of liquidity is one of the important indicators of diesel.We use diesel label is its solidifying point.Condensation point and diesel low temperature performance of no direct corresponding relationship.Before because in diesel coagulation precipitation of paraffin crystal, different crude oil and refining methods of diesel, the shape and size of the crystals are different, they tend to jam the mesh of diesel engine, oil supply disruptions.Therefore, the use of a diesel engine car should pay attention to according to the use of environment temperature to select the appropriate product label.
Diesel before use should be fully precipitation, filtration, to eliminate impurities, generally should not be less than 48 hours.This is because the high speed diesel engine high pressure oil pump and nozzle are very precision parts, mechanical impurities into slightly, will badly worn.In addition, the diesel oil under the condition of low temperature when using, should be preheated.Different label diesel, because of its quality index except the solidifying point basic same, so you can in suitable seasons under the condition of oil to mix.

The internal structure of diesel generator set control panel.

Diesel genset simple are commonly inside the control panel is equipped with voltage regulator, silicon rectifier diode, resistor, such as automatic air switch and current transformer parts, more complex in the control panel to install overload and short circuit protection device, electronic governor, SCR, relay, and all sorts of insurance device and small transformer and other electrical equipment.

Diesel generator set ten taboos

In order to make diesel genset can operate properly, Shandong huaquan power co.,ltd  Talk to you use generating set of the ten big taboo.
First, no cooling water, or add boiling water after start engine start to add cooling water, can make the hot cylinder liner, cylinder head and other important components caused by the sudden encounter cold cracking or deformation;To the cold snap in body plus 100 ℃ hot water, also can shock crack cylinder head and the body, should stay when the temperature dropped to 60 ~ 70 ℃ to join again.
Second, is not in accordance with the provisions, diesel engine oil supply should not be at start up will stress the handle into the "work" out oil supply, and should be before the launch will throttle lever on the location of the fuel supply.According to the instructions of the harm is: not waste fuel;Redundant diesel will scour the cylinder wall, make the deterioration of lubrication between the piston, piston ring and cylinder liner and aggravate the wear;Residual oil into the oil pan will be diluted oil lubrication and the effect;Incomplete combustion of diesel will be too much in the cylinder form carbon deposition.
Three, cart to start the diesel engine under the condition of the cold car engine oil sticky cart, exacerbate between each moving parts wear and tear, thus reduce the service life of the locomotive.
Four, not on schedule in used lubricating oil, fuel oil in the cold weather season, if not timely change of low viscosity lubricating oil and fuel oil, diesel engine is hard to start.
Five, with open flame roasting the oil pan and the fire started at inlet pipe to prevent fire, application soft fire, coal fire in a certain distance baking of diesel engine oil pan, slowly shake shaft oil at the same time, let the oil evenly heat, make each part have been lubrication.If a fire started on the diesel engine intake pipe, can make the material burning ash and hard sundries sucked into the cylinder, intake and exhaust door closed lax caused to speed up the cylinder wear.Six, long time using electro-thermal plug, flame preheater electro-thermal plug, flame preheater of the heating element for the heating wire, its power consumption and heat output is very big, use for a long time can damage because of rapid discharge of battery, at the same time also can burn out heating wire.Electric plug, therefore, each time not more than 1 minute continuous use, every time the flame preheater of continuous use time to control within 20 seconds.
Seven, to add oil to add oil cylinder cylinder directly, can have the effect of sealing pressurization warming, is advantageous for the diesel engine cold start, but cannot complete combustion engine oil, easy to produce carbon, lessened the flexibility of piston ring, cylinder sealing performance;In addition, will also accelerate the wear of cylinder liner, resulting in a decline in the power of the diesel engine, make it more difficult to start, so can't directly to add oil cylinder.
Eight, directly to the gasoline pumped into the intake pipe gas ignition point was lower than those of diesel, before diesel combustion.So directly to the gas inlet pipe, and can make the engine work rough and produces strong knocking phenomenon, serious when still can happen engine inversion.
Nine, long time continuous to start the diesel engine is under the condition of the low voltage, high current work, use for a long time will damage the battery.The continuous working time shall not be more than 5 seconds;Once started, should every 15 seconds to start again.
Ten, just start the high-speed diesel engine has just started, the temperature of the lubricating oil is low, the liquidity is poor, high-speed operation immediately, easy to cause the movement parts sharply due to lack of lubrication and wear, serious when still can happen tile burning shaft.

The significance of carbon deposition in diesel generator set

Diesel generator set carbon most users have not heard this word, also don't know how this works.For technical personnel must know diesel genset, the concept of carbon deposition and the reasons of this phenomenon, and will handle and solve the problem.
So-called carbon deposition is, in fact, diesel fuel and diesel generating set into the combustion chamber of the oil product of incomplete combustion, on top of the diesel engine piston, valve and combustion chamber wall around to produce carbon deposition is a more common phenomenon.Large amounts of carbon deposition will have influence on the performance of the diesel generator set, its ultimate performance: the worsen poor combustion, heat transfer and reduce the reliability of the fuel injector.
Generating set the causes of carbon deposition are many, many years of technical personnel at six summarizes the following:
1. The fuel injector work is not normal, such as spray, drip, too high or too low injection pressure and injection time too early or too late, fuel injection quantity too much, will make some fuel incomplete combustion.
2. Oil is serious.
3. Leakage is serious.
4. The cooling water temperature is too low, affect the normal combustion of the fuel.
5. Diesel fuel and oil brand, quality is poor, the formation of carbon residue after burning.
6. Diesel engine overload or temperature is too high, fire early to make the fuel combustion is not completely.

Weaver of diesel generator set

With the development of various industries, users of diesel genset power requirements is more and more big, the diesel generator set technology is becoming more and more mature, but considering the cost problem, many users choose to use more machine weaver network generator as a backup power.So, what are the typical features of diesel generating sets weaver?
1. The power supply system is relatively reliable and continuous;Because many sets of generating units and got behind a power grid, power supply voltage and frequency stability, can bear larger load change.
2. Is more economical.Can according to the size of the user load, in the small power generator set the appropriate stations and to reduce power load unit small run of fuel oil, waste oil.Such as user normal use only need to 600 kw, but, sometimes need to load operation of 800 kw.At that time, if choose a 800 kw generator, its cost is far better than to choose two 600 kw generator set high many, weaver when using the engine oil and fuel consumption is also much less.And consider all aspects, and, of course, recommended to choose two 600 kw of the weaver, when only need to use the 600 kw load, only need to open a machine, if again big, then you can drive a machine designer then use.
3. The maintenance, the maintenance is more convenient and more diesel generator set in parallel use, can focus on scheduling and distribution of active load and reactive load, convenient repair and maintenance in a timely manner.

Note:
Diesel generator set after the first use 20 hours,the oil should be replaced immediately.For every 1000 hours after use,must replace the oil.

The purpose of the diesel genset has a lot of, also very widely used.China full power as a professional diesel genset manufacturer, said the main purpose of the diesel genset.
1.Self-provided power supply: no net electricity supply or supply is normal, in the case of the electrical need not too big.
2. Standby power: also known as the emergency power supply reliability of power supply security demanding scenarios.
3. The peaking power: make up the net electricity supply, under the condition of electricity.
4. Mobile power supply, mobile power supply is generally designed to power vehicles form, used in work flow, there are also some mobile power as the nature of the emergency power supply.
Diesel genset is most self-provided power supply and standby power supply, has been widely applied in communication stations, to ensure the reliability and stability of power system.

The influence of elevated altitude use of diesel generator set

1. With the increase of altitude, the environment temperature is lower than that in plain area, generally every 1000 m, the environment temperature is about 6 degrees Celsius, and thin air, because the plateau as a result, the start of the diesel generator sex than plain area is poor.Users in the use, and low temperature start corresponding auxiliary start measures should be taken.
2. The output of the diesel genset current will change along with the change of altitude.Altitude increases, the power of diesel generator set, that is, output current, the fuel consumption rate, the effect is to spread to the electrical performance index in different degrees.Due to the rise of altitude, the boiling point of water.At the same time, wind pressure and cooling air quality of cooling air is reduced, and heat release per kilowatt in unit time increases, so the cooling system of heat dissipation conditions worse than plain.At high altitudes shoulds not be commonly use open cooling loop, closed cooling system pressure can be used to improve the plateau when using the boiling point of coolant.
3. As a result of the plateau low pressure, thin air, less oxygen component, the environment temperature is low, especially for natural intake diesel engine, combustion condition is poor, due to lack of air inflow diesel generator can't send the original is the nominal power, displacement, speed is different, so the ability to work in the plateau is not the same.When used in plateau, every 1000 m, rising power booster is about 6-10%, booster about 2 ~ 5%, so in plateau, use for a long time should be according to the local elevation, when the appropriate reduce oil.
4. The load moment of change, will cause the engine torque moment of change, and the output power of diesel engine is not instantaneous change, in general, instantaneous voltage and the instantaneous speed of these two indexes is not affected by altitude, but for the diesel units, the lagging behind of the supercharger response speed affect the response speed of the diesel engine rotating speed, the two measures was increased.

How to prolong the service life of diesel generator set.

Diesel genset parts contained in the air filter diesel filter, oil filter, and the three kinds of filter, to extend the service life of diesel generator set, in use process, will strengthen the air filter, oil filter, diesel filter and maintenance, give full play to their role.Air filter in the installation not packing, reverse, or when the fault with the sealing gasket and rubber connecting pipe, and ensure good sealing.Use of air filter paper dust cup, 50-100 working hours, every time to remove dust, can soft brush to brush the dust off, if the working time or damaged more than 500 hours, should be timely replacement.Using oil bath air filter, 100-200 hours per work, should be cleaned clean diesel filter, and replace the oil, if the filter has been broken, will need to be replaced immediately, and pay attention to in use, in accordance with the provisions, add the oil.Have filter in diesel generator set use if not timely maintenance, filter blockage, oil pressure increases, the relief valve opens, lubricating oil directly into the main oil way, exacerbate lubrication on the surface of the wear and tear, affect the service life of the diesel generator set.Therefore, the oil filter every 180-200 work hours, is clean, found damaged, should be replaced immediately, to prevent impurities from entering the smooth surface.Change garments according to the using a diesel genset, still should clean surface of crankcase and lubrication, method is to use the oil, kerosene and diesel blend to make washing oil, deal with the various parts of the whole fuel oil supply system for cleaning.Use diesel, should conform to the requirements of the season, and after 48 hours of precipitation purification treatment.

How to choose the emergency diesel generator set

As the power generation system is indispensable equipment, the use function of emergency electric generator has a huge, in some power dense, supermarket, hospital, construction sites, etc., use of electricity will be heavy, how to alleviate power huge gap, that is about to rely on the emergency generator.
Most of the friends will prepared emergency generator, the use of the most common is small diesel generators, how should choose?As a professional generator manufacturer for your detailed introduction:
First of all, small yo generator characteristics.
Emergency diesel generator is mainly used in important place, in an emergency or accident happens instantaneous power, through the emergency generator back quickly and to extend the time of a power supply, common for small diesel generators, main characteristic is: the power quickly, for 12 hours;External power supply back up, automatically cut off power supply, ensure the equipment can use for a long time.
Second, how to choose the generator.
Demand for different occasions, electricity generator is not the same.When have many sets of genset spare, generally only set up an emergency diesel generator set.From a reliability considering also can choose two sets of parallel power supply.
In addition, the emergency units for choose high speed, pressure, low fuel consumption, with the capacity of diesel generator set.So easy to use on the large equipment, the most important point, generator made selection with brushless excitation or compound excitation device of synchronous motor, more reliable, low failure rate, maintenance is convenient, save maintenance time.
In general, choose emergency diesel generators, is to select stable, efficient and convenient equipment, so as to ensure the supply of electricity is insufficient, does not affect the development of the construction schedule, the follow-up is more simple and convenient.

Noise analysis of diesel generator set

The noise of the diesel generator set is composed of a variety of sound source complex sound source.According to the way of noise radiation, can be divided into the aerodynamic noise, surface radiation and electromagnetic noise.According to the production reason, diesel generating sets surface radiated noise can be divided into combustion noise and mechanical noise again.Lifting the aerodynamic noise is the diesel generator set noise of main noise sources.
1. The aerodynamic noise is due to the unsteady process of the gas, which is by the disturbance of the gas and gas interact with objects of the noise of the diesel generator set.The aerodynamic noise directly to the atmospheric radiation, including air intake and exhaust noise and cooling fan noise.
2. The electromagnetic noise is generated by the generator rotor high-speed rotation in the electromagnetic field of the noise of the diesel generator set.
3. The combustion noise and mechanical noise is difficult to distinguish between, is usually due to diesel generator set combustion formation pressure in the cylinder by cylinder head, piston, connecting rod, crankshaft, the body to the outside noise radiation of diesel generating set is called combustion noise.The piston of the cylinder liner strikes and movement of the mechanical vibration of diesel generator set noise called mechanical noise.Generally di diesel engine combustion noise than mechanical noise, instead of a di diesel engine mechanical noise is higher than that of combustion noise.But low speed combustion noise were higher than that of mechanical noise.

The choice of diesel generator set factors should be considered.

Unit selection should consider the factors mainly include mechanical and electrical properties, the purpose of the unit, load capacity and the change range of automation function, etc.
1. The purpose of the unit.Because the diesel generator set can be used on three kinds of commonly used, standby, emergency situation.In turn, different USES is different to the requirement of diesel generator set.
2. Load capacity.Should choose according to different purposes of load capacity and load range, determine the diesel generator set of single machine capacity and the capacity of standby diesel generator set.
3.The machine (mainly refers to the use of altitude and climate conditions).
