Diesel generator is a kind of independent power generation equipment.In fact, unit most of the time in standby state,the actual chance to put into use is less.usually,give priority to commissioning.lack of a perfect test and maintenance methods.But this emergency power supply is indispensable.Diesel generators use less in peacetime,how to make temergency power supply timely, safe and reliable operation, after the power and it can immediately stop.
First,check the battery of Diesel engine generators.as standby power supply is not often put into use,the Diesel generatorcan the normal starting or not, the key lies in cell maintenance.Such as battery problems, more common situation is: there is no current voltage, we can hear within the starter motor electromagnetic valve suction together voice.but can not take even the axis.three reasons of Battery problems lead to can't stop:When in commissioning stop charging,it will will lead to low battery.2.Battery power supply shortage,Due to the electromagnetic valve suction is not enough ,not sealed from four out of the oil hole extrusive fuel, cause Diesel engine generators can't stop.3.Domestic battery life usually is two years,do not change regularly.
Second, start electromagnetic valve inspection.when Diesel generator at run time, people summed up a set of inspection method :see, listen,touch,smell.the United States cummins Diesel generator for example,just need to press the start button, after three seconds, it can start.In this three seconds,two clatter can be heard.once you can't hear the second ring,you have to check if start solenoid valve is normal work or not.if the electromagnetic coil fusing,Diesel generators of course can't start.
Third, the diesel oil inspection.as unit long-term in static,unit itself all kinds of materials complex chemical physical change with oil,cooling water and diesel air.thus unit will be put bad.pay attention to the problem of oil.in order to fire safety, usually the diesel fuel tank in a closed room.Due to the atmospheric water vapor happened in condensation phenomenon ,such diesel will rust precision coupling a plunger.serious damage to the unit.Diesel generators lubricating oilis a long,a long time storage,physical and chemical properties of lubricating oil can produce change, cause unit work lubrication state deterioration.it is easy to cause the subjection of the Diesel engine generators.
