>> Shandong heracles loader H180 with CE, H580 heracles loaders, qingdao heracles with SGS
The hot car hold up of the heracles H180 may also be caused by the hydraulic system failure. heracles H180 Common reasons include: excessive pump power, worn pump regulators, excessive pressure and flow of pump valve group, worn pump internal components, etc
Chapter II Maintenance Methods
heracles loaders Maintenance idea:
First, the heracles loaders mismatch between the power of the excavator hydraulic system (mainly from the main hydraulic pump) and the power of the engine may cause the heracles loader H580 to hold the vehicle. What is the cause of the mismatch between the power of the excavator hydraulic system and the power of the engine?
The shandong heracles power of theshandong heracles hydraulic pump has increased abnormally (the engine power is normal at this time). The reasons for the increase of hydraulic pump power are as follows: 1) The 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 regulator feedback system malfunction. 5) The internal servo mechanism of the hydraulic pump is worn, stuck and leaked. www.heraclesloader.com
