Many owners often encounter the problem of excavator holding back! Most of the owners reflect the excavator, and the excavator is actually working. Today, I will explain to you the solution of the excavator holding back the vehicle during the work of the excavator. I hope the following method can eliminate the problem that your excavator is always holding back your car at work.
Excavator maintenance failure inspection method:
First of all, check whether the fuel oil circuit of the excavator is faulty. If it is confirmed that there is no problem in the fuel oil circuit, then mainly check whether the internal control servo piston of the main pump regulator is aging and draining oil. If the aging and draining oil will cause the main pump to increase the oil flow (ie, the main pump power becomes larger) and the engine The relatively unchanged power will cause the excavator to hold back.
Requires a very strict power curve matching, maintenance and disposal of the Komatsu excavator: the maintenance value and repair level after the aging of the regulator are extremely low. Victory rate is extremely low, generally no one needs to repair, two regulator assemblies should be replaced, and the on-site commissioning of the car will be good soon.
If the power of the hydraulic pump of the excavator is greater than the power of the engine, the failure of the excavator will occur. Secondly, the excavator hydraulic pump itself also has a certain power.
Reduce the power of the hydraulic pump to 95 ‰ of the engine power. Solution: Commission the hydraulic pump.
The above is the reason analysis and solution for the problem of excavator holding vehicle, I hope it can be helpful to everyone.
