Hello, everyone! , Here to tell everyone about the excavator stalling the car. The holding of the excavator is a very common fault, especially in the winter, when the holding of the excavator basically causes the entire vehicle to stall, then how do the old drivers handle this problem when they do maintenance? Today, the excavator maintenance technician will share with you one point, the troubleshooting methods after the Kobelco excavator stalls, there are 8 common reasons for the "Kobelco excavator stalls stall" failure:
1 The temperature control switch of the excavator is not very good.
2 Or the relay of the excavator is not so good.
3 It all means that the air filter of the excavator is dirty or destroyed.
4 The oil circuit of the excavator engine is blocked.
5 Insufficient diesel supply and gas intake.
6 The car oil filter is clogged.
7 The mediator is stuck.
8 Except for many reasons, it means that the diesel engine used by Kobelco excavators is very poor, which will also cause the excavator to stall.
It's all one point, everyone add:
Generally, there is a failure of the excavator to hold the car, all because the output power of the hydraulic pump of the excavator exceeds the output power of the diesel engine, so that the excavator is holding the car or even stalling. Therefore, after the failure is caused, the excavation must be checked initially Whether the output power of the hydraulic pump of the machine and the output power of the diesel engine are matched. The method of inspection can be to reduce the output power of the hydraulic pump of the excavator, and then check whether everything is normal in the work of the excavator? If an abnormality is still found, just It shows that it is not a problem with the hydraulic pump, but also to check the diesel engine. Generally, the key is to persevere in the fuel supply system software of the diesel engine to see if the fuel supply pipeline is blocked, or the filter element is darkened or darkened. The oil filter may be blocked or blocked.
Precautions:
If the Kobelco excavator is in use when the excavator stops the car or even stalls, in addition to the exhaust pipe emitting black smoke, then the cause of the failure must be that the output power of the excavator hydraulic pump is not the same as the engine displacement. Paired.
If it is not black smoke from the exhaust pipe, it means that the fuel supply of the Kobelco excavator cannot be increased with the increase of the diesel engine load. It is also necessary to check the fuel supply system software of the diesel engine. Is there a blockage? Is the working pressure of the diesel engine fuel supply slightly lower?
