Reasons why the speed can not rise when the engine accelerates

There is a customer asking the engine of the diesel generator to low speed, but the speed of the acceleration cannot be increased, which is the lack of oil supply. Jiangsu Xinglu sales professionals answer:

(1) Problem:
1 The fuel injection pump is adjusted and reduces the amount of oil supply.
2 The governor spring is lowered due to fatigue.
3 The fuel injection pump plunger and sleeve, the injector needle valve is severely worn by the needle valve body, which increases the water leakage in the pump oil, and the amount of oil is relatively reduced.
4 There is air in the oil road.

(2) Treatment method:

When the engine is insufficient, if the low speed is good, it is normal, and the smoke is normal, it means that the engine is combunned, that is, the diesel injection quality is good, the oil supply start time is normal, the cylinder sealing is good and the intake is sufficient.
1 In the case of normal low pressure oil roads, first check whether the looseness of the throttle connection pin and the length adjustment of the connection rods are appropriate. When the throttle is in the end, the speed limit screw should be in contact with the limit block when the gallery is in large positions in ZUI. Otherwise it should be adjusted.
2 discharge the air in the oil road.
3 Turn the injector pump on the fuel injection pump test bench, so that the fault is excluded.
