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.
