It is a common machine fault that the excavator stalls when it is working. Engine speed loss refers to the failure of engine speed reduction during excavator operation. Serious speed loss above 300 rpm is likely to cause sudden flameout of the excavator. So, what's the matter with the excavator stalling? Here are some possible reasons.
Reduction of engine power
It is recommended to check the low-pressure oil circuit, high-pressure oil circuit, intake and exhaust system, etc., as well as the cylinder compression force.
1. In fact, you can also see the color of smoke. If there is no black smoke at the speed drop, it means that the fuel supply is low, resulting in low engine power.
2. If there is black smoke, it indicates that the combustion is not good. One is poor fuel atomization, and the other is insufficient air intake.
Excessive hydraulic power
Check the hydraulic pressure. If the pressure is normal, the flow may be too large. The most critical element for regulating the flow is the regulator. The regulator may have problems with a machine that has been used for a long time.
When the air intake system leaks or is blocked
It will cause insufficient air supply to the engine, insufficient combustion of fuel, speed loss and black smoke.
fuel system?
The fuel supply circuit connector is loose or the pipeline is broken, causing fuel leakage or foreign matter blockage, resulting in insufficient fuel supply. In addition to speed loss, it may also cause flameout.
The above briefly summarizes several common reasons for the stalling of Case excavator. Before troubleshooting, you must check and measure to determine the cause of the fault, so that you can accurately and quickly solve the problem. If you can't solve the excavator fault yourself, you can find a professional excavator maintenance technician to help you solve the excavator fault.
