Diesel Generator Tech

In the process of use and operation of diesel generator, what operations should not be done? Why we shouldn't do them?Today Starlight Power generator manufacturer answers for you.  1.After genset start-up, we should not runs it with load without warming up. When start up without warming up, due to the high viscosity and poor fluidity of the oil, the oil pump is not enough to supply oil, and the friction surface of the machine is badly lubricated due to lack of oil, resulting in sharp wear, and even cylinder pulling and bush burning. Therefore, the diesel engine should run at idle speed and warm up after cooling, and then run with load when the oil temperature reaches 40℃. The genset should be started in low gear, and drive in each gear step by step for a certain mileage until the oil temperature is normal and the oil supply is sufficient. Then can run normally.   2.We should not operate genset with load under lack of oil. At this time, due to the lack of oil supply, the surfac...

  640kw diesel generator manufacturer will answer for you. For person who use diesel generator, at some time, the purchased cost is less than usage cost, especially fuel consumption. Therefore, it is important key to save diesel fuel.   Base on the cognition of car diesel engine, many people think the fuel consumption of the generator set is in direct proportion to the load, and the greater the load, the more fuel is consumed. But is that really the case? Usually, fuel consumption of generator set is related to two aspects: one is the fuel consumption rate of the unit itself, which is usually unable to have a greater change; the other is the size of the load. For the purpose of fuel saving, many people control the load within the standard range of rated load, but the  fuel consumption  is still not ideal, why? What is relationship between fuel consumption and load on diesel generator set? In normal situation, when brand and engine model of diesel generator is same, t...

 

  Why is the insulation resistance of 200kw diesel generator reduced? Faults:  under thermal stability, insulation resistance of  200kw diesel generator  is lower than 0.5m Ω, lower than 2m Ω in cold state. Reason: 1)Diesel generator set is stored in humid environment or the alternator winding is affected by moisture during transportation. 2)During maintenance and cleaning working, the insulation of motor winding is damaged., or the insulation is damaged in the process of alternator overhaul and wire embedding. 3)Conductive dust in the surrounding air (e.g. metallurgical or coal industrial areas) or acid and alkaline vapors (such as chemical industrial areas) invade the alternator and corrode the alternator insulation. 4)Natural aging of generator winding insulation.   How to solve the reduction of insulation resistance of 200kw generator? 1)AC synchronous generator affected with damp must be dried, otherwise the generator may be burnt out due to insulation dama...

Today Starlight Power introduces how to prevent emergency diesel generator set from burning out. Hope it is helpful for everybody. 1.Keep diesel generator set clean. In the operation of diesel generator set, if dust, water stains and other debris enter into the diesel generator set, it will form short-circuit medium, which can damage the insulation layer of conductor and form turn to turn short circuit. With the increase of current and temperature, the diesel generator set will be burned. Therefore, we should prevent dust, water stains and other debris from entering into diesel generator set. At the same time, we should also often clean the exterior of diesel generator set. Do not let dust and other sundries exist in the cooling rib of diesel generator set, so as to ensure the heat dissipation of diesel generator set. 2.Frequent inspection, listen carefully, when smell something, immediately shut down. Check the diesel generator set for vibration, noise and abnormal smell. In the opera...
