The speed loss of excavator engine is one of the problems that many operators have encountered, but because the cost of excavator shutdown is too high, most people will choose to continue construction and observe at any time when encountering minor failures. But the fault is not terrible. What I'm afraid of is that it will lead to a major fault!
1. The hydraulic system of the excavator fails, causing the engine to lose speed. The hydraulic pump can not change the displacement normally, causing the system pressure to be too high, speed loss and machine holding fault
2. The excavator engine has insufficient output power, resulting in speed loss. The output power is lower than the rated power. There is also a problem with the main pump
3. The engine stalls due to the clearance of the solenoid valve. The fuel supply is insufficient, causing the engine to stall
4. There are many reasons for speed loss, such as incorrect valve clearance, wrong fuel injection timing, damaged turbocharger, defective brake, etc.
The problem of engine stalling is one of the most difficult faults to deal with. Many bosses also want to eradicate the fault once and for all, but the idea is good and it is very difficult to achieve. Because there are many reasons for the failure, such as the situation introduced today. Before troubleshooting, you must determine the cause of the failure through inspection and measurement, so that you can solve the problem accurately and quickly!
