It is a common machine fault that the excavator suddenly loses speed when working. The engine must not be taken lightly when it loses speed. Many operators often do not know how to deal with it at this time. In serious cases, they are forced to stop running. How to deal with excavator speed loss?
1 When the excavator engine slows down, the excavator driver should first check whether the diesel used by the excavator has deteriorated? Deteriorating diesel or adding more diesel will cause the engine to lose speed, and finally, the blockage of the oil circuit will also cause the engine to lose speed.
2 Secondly, check whether the excavator engine is electric injection or direct injection, and 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 speed loss occurs under engine load.
5 Finally, check the engine to see if it is the engine failure that causes the excavator engine to lose speed.
Be careful when dealing with faults. Don't ignore faults in details. Some simple causes of faults are easy to be ignored when troubleshooting! In addition, if you are not very experienced in maintenance and disassembly, you are suggested to find a professional technician to avoid damaging other parts due to disassembly.
