Many machine owners often encounter the problem of holding the excavator! Today, let's talk about the solution to the problem that Komatsu excavator is stuck in the working process. It is hoped that the following methods can eliminate the problem that your excavator is always stuck in operation.
Inspection method for excavator maintenance fault:
First of all, check whether the fuel circuit of the excavator is faulty. If your Komatsu excavator ZX200 is stuck during operation. If it is confirmed that there is no problem with the fuel oil circuit, mainly check whether the auxiliary control servo piston in the main pump regulator is aging and leaking oil. If the aging and leaking oil will lead to the increase of the oil flow of the main pump (that is, the power of the main pump becomes larger) and the engine power does not change at this time, it will cause the excavator to choke.
Strict power curve matching is required. Maintenance and disposal of Komatsu excavator hold car: the maintenance value and level of the regulator after aging are very low. The success rate is very low. Generally, there is no one to repair it. Two regulator assemblies should be replaced and the on-site commissioning of the vehicle will be completed soon.
If the power of the hydraulic pump of the excavator is greater than the power of the engine, the excavator will be blocked. Secondly, the hydraulic pump of excavator also has certain power.
Reduce the power of the hydraulic pump to 95 ‰ of the engine power. Solution: debug the hydraulic pump.
The above is the cause analysis and solution to the problem of backhoe choking. I hope it can help you.
