How To Protect Hydraulic Pump When Scraper Tunnel Mucking Loader Is Operating

Before using the wheeled mucking loader, first preheat the hydraulic system. When parked, the upper hydraulic oil will flow to the lower part. mucking machine is recommended to use small throttle operation at the beginning of use every day, and then use mucking loader medium throttle operation after the formation of the oil film of the piston cylinder, so as to protect the hydraulic system. Invalid operation process will not only cause the oil temperature rise, but also produce abnormal vibration, which leads to impurities into the cylinder block, it is strictly prohibited to let the wheel skimming machine invalid operation. In the whole operation state, mucking machine timely supplement the lubricating oil (2h/ time), stop working to supplement the lubricating oil, the oil will enter the room, produce abnormal high pressure oil into the hydraulic system, damage the hydraulic pump.

Long-term storage wheel skimming machine, first remove the steel brazing, discharge the nitrogen in the upper cylinder to the piston top to the end, to avoid the piston exposed part of rust or hair damage the main engine pump.tunnel mucking loader.

The hydraulic oil pollution is the main cause of the failure of the hydraulic pump, so the hydraulic oil pollution should be confirmed in time. tunnel mucking loader Lack of hydraulic oil will produce cavitation phenomenon resulting in hydraulic pump failure. The oil seal is a wearing part. It is recommended to replace the oil seal after the hammer works for 600h ~ 800h. When the oil seal of the wheeled slag scraper leaks oil, stop working immediately and replace the oil seal. Otherwise, the side dust is easy to enter the hydraulic system, damage the hydraulic system and damage the hydraulic pump.
