When cummins diesel generator set is working, have you ever met that the set cannot produce the required power? What is the reason for this? Jiangsu Meao Power Technology Co., Ltd. for you to explain:
One, the valve mechanism and the intake and exhaust system failure, resulting in the failure of the specified power
Cause: The clearance between inlet and exhaust valves and rocker arm is incorrect; Air timing is not correct; Valve spring damage; Valve has carbon leakage sealing surface; Air filter blockage; Exhaust pipe and muffler carbon accumulation is serious, exhaust is not smooth.
Treatment method: check and adjust to the specified gap; Check and readjust valve timing; Replace the valve spring; Remove carbon accumulation, grinding valve; Clean air filter; Remove carbon deposits.
Two, the compression pressure is not enough to cause the specified power
Reason: cylinder cover and body close place leakage, its performance in the speed when a flow out of the gasket, cylinder cover nut loose; Cylinder head gasket damaged. The piston ring is stuck, the valve rod is not flexible, the cylinder head injector hole leaks, the injector tight cap copper washer is damaged, the injector hole plane is not clean; Nozzle and injector body joint surface leakage.
Treatment method: check the joint surface of cylinder cover and body, replace cylinder pad, clean and repair. Replace the gasket; Clean the seat hole; Tighten the injector cap or the grinding plane.
Three, the water temperature is too high to send the specified power
Cause: Diesel engine overheating (cooling or lubrication system failure).
Treatment: overhaul the cooling and lubrication system and remove the scale in the water jacket, clean the oil cooler.
Four, the oil supply is not normal, the fuel system failure caused by the failure of the specified power
Reason: fuel system into the air; Fuel injection pump failure; The fuel injector is out of order.
Treatment method: release the air in the fuel system according to the foregoing; Repair or replace the parts; Repair or replace the injector parts.
When diesel generating sets couldn’t send the regulation of power, can be the first into the air and fuel injection quantity for inspection, determine the compression pressure is big enough, the reasons for faults, on the basis of this it is the effective way to solve the problem, the above is why cummins diesel generator set is the key to the regulation of power sharing, hope to be of help.
