The mobile light tower desiel low speed of the engine is good, but the speed cannot rise when accelerating, and the driving is weak, which is caused by the insufficient circulation of oil
① Improper adjustment of the fuel injection pump reduces the oil supply.
② The elastic force of governor spring is reduced due to fatigue. When the mobile lighting tower trailer accelerator pedal to the end, the oil volume adjustment rod can not move forward to the end, resulting in the oil supply of the fuel injection pump is reduced, the engine can not reach the rated speed.
③ The plunger and sleeve of the fuel injection pump, the needle valve and the needle valve body of the fuel injection pump are seriously worn, so that the mobile light tower desiel leakage increases and the oil supply is relatively reduced.
④ Improper adjustment of the throttle control pull rod, or the throttle pedal pin is too open, so that the mobile lighting tower trailer accelerator pedal can not be in place, resulting in too little full load oil supply.
⑤ There is air in the oil circuit.
