What are the root causes of the failure of small excavator engine speed

[BONOVO]

What are the root causes of small excavatorengine speed failure? Bottom wheel excavatormanufacturers to explain the relevant content.

1. Too much oil in the air filter oil in the inertia force oil bath. It is sucked into the cylinder and ignited. It's the same as boosting energy supply, but faster and faster.

2. The assembly bend or oil plug is likely to cause the plunger of the fuel injection pump to rotate and lose the rate adjustment support frame. In particular, the multi-cylinder oil pump is under load discharge and cannot change the fuel supply to cause system failure.

3. The motor governor drive sleeve of the single cylinder diesel engine single injection pump is stuck, resulting in the failure of the speed adjustment system.

4. Part of the fuel injection pump plunger sleeve inlet and return port are on the same parallel plane. If the screw on the plunger sleeve is too long to block the oil return port, the engine oil will become worse and gradually begin to supply oil. Surges can also cause acceleration.

5. The fuel pump adjustment drive gear is stuck in the fuel transport part, or the rack and pinion and the motor governor rod are loose and fail.

6. Too much wetting of the motor governor housing will block the rate opening and interfere with the rate adjustment.

The root cause of the failure of the relevant small excavatorengine speed interpreted by the wheeled excavatormanufacturer is these, and I hope to have the corresponding help for you.
