There are many kinds of faults for excavator engines. Before that, we have explained the problem of abnormal sound, burning oil and carbon deposition. What's the problem of engine speed loss when working with long arm excavator?
1, the diesel oil road fault of the excavator, when the general words when the diesel oil road is blocked, it may cause the phenomenon of speed drop.
2, the hydraulic system of excavator fails, the hydraulic pump can not be normal displacement change, cause the system pressure is too high, it may be my fault at the same time speed.
3, the engine output power shortage of excavator, the output power is lower than the rated power, speed is too low.
4, the engine's fuel quality is too poor or the fuel water content is too high, which will cause the engine's power shortage and cause the speed drop phenomenon.
5, when the air intake system is leaking or blocking, the engine gas supply will be inadequate, resulting in inadequate combustion of fuel, resulting in the loss of speed and black smoke.
6, with the long arm excavator, the gap between the solenoid valve is too large and the fuel supply is insufficient, which causes the engine to lose speed.
7, the oil system oil supply loop is loose or broken, causing fuel leakage or foreign matter blockage, resulting in insufficient oil supply. Besides falling speed, it may cause stall.
8, there are many reasons for the failure, such as valve gap, injection timing error, turbocharger damage, brake malfunction, and so on.
The above is the knowledge that Xiao Bian tells you. We have strict working attitude and skilled working skills. We will ensure that tasks are done accurately and efficiently.
