It seems that the speed loss of the excavator is a minor problem, but if it cannot be handled in time, it may cause major failures such as the holding up of the excavator. I hope that the majority of operators and owners will pay attention to it. Come down to answer the reasons and troubleshooting for the speed loss of the excavator.
Reasons for speed loss:
1 Diesel oil circuit problem. (Generally, the diesel oil circuit is blocked); Low fuel pressure and poor fuel quality.
2. The clearance of the solenoid valve is too large and the oil supply is insufficient, resulting in the excavator engine stalling.
3. Excessive engine load; One of the engine cylinder operation setting values of the engine is incorrect; Engine failure. (The speed is too low)
4. The air intake system leaks.
5. Hydraulic failure. Generally, the excavator engine loses speed. The main reason is the change of load. When the hydraulic system fails and the displacement cannot be changed, it is easy to lose speed or hold up.
1 When the excavator engine loses speed, the excavator master should first check whether the diesel oil used by the excavator has deteriorated? Jiaduo? Or is there any impurity? Is the oil way blocked?
2 Secondly, check whether the excavator is an electronic injection engine or a direct injection engine, and then check the direct injection engine step by step.
3 After checking the diesel circuit, check the valve clearance of the engine and the engine speed?
4. Then check whether the excavator engine slows down when the engine is loaded?
5 Finally, check the hydraulic system to see if it is the engine failure that causes the excavator engine to lose speed.
The driver shall pay attention to the correct use and maintenance of the excavator. In case of a car holding due to the speed drop of the excavator, the driver shall timely check and remove the fault to ensure the normal and stable operation of the excavator. See the hotline below for details!
