During using, The hot wheel loader hold up of the excavator may also be caused by the hydraulic system failure. Common reasons include: excessive pump power, worn pump regulators, excessive pressure and flow of pump valve group, elite wheel Loder worn pump internal components, etc
Chapter II 1 ton wheel Loder Maintenance Methods
Maintenance idea:
First, the pitbull loader mismatch between the power of the excavator hydraulic system (mainly from the main hydraulic pump) and the power of the engine may cause the excavator to hold the vehicle. What is the loader cs910pro cause of the mismatch between the power of the excavator hydraulic system and the power of the engine?
The loader toros power of the pitbull loader hydraulic pump has increased abnormally (the engine power is normal at this time). The pitbull loader reasons for the increase of hydraulic pump power are as follows: 1) The pitbull loader abnormal increase of hydraulic oil temperature leads to the thermal expansion and stagnation of parts of hydraulic pump servo mechanism. 2) The regulator is worn and aged, and the internal leakage seriously interrupts the required power feedback on regulation. 3) The sensor of the hydraulic pump fails (the positive control system is more obvious), and the negative control has little effect. 4) Insufficient first arrival pressure makes the mini loader titan regulator feedback system malfunction. 5) The 1 ton wheel Loder internal servo mechanism of the hydraulic pump is worn, stuck and leaked. www.haiqinmachinery.com
