How To Maintain The Hydraulic Motor Of Mucking Rock Loader

When it comes to the opening and closing of the slagging mechanism, there is no need to set up special control oil circuit. When the hydraulic motor inlet pressure of the small mucking rock loader is higher than the brake opening pressure, the mechanical brake will start automatically, and when the hydraulic motor inlet pressure of the mucking rock loader is lower than the brake opening pressure, the mechanical brake will automatically stop. The brake opening pressure can be adjusted in the range of 18%~25% of the rated pressure of the hydraulic motor, and the braking torque will be changed accordingly.mucking rock loader.

In general, it is necessary to carry out pickling on the motor pipeline and pipe joint connected with the mucking rock loader, and it is required to carry out pressure cleaning on the pipeline before the pipeline is connected to the motor, the specific method; First connect the inlet and outlet tubing of the motor (do not connect the motor, direct docking); Start the pump and the reversing valve to make the hydraulic oil of the mine slagging machine circulate for 10~15 minutes on the pipeline. (positive and negative directions should be tested), after the purpose of making the residual impurities on the pipeline and valve directly back to the oil, and then precipitate the oil, clean the tank, and ensure the cleanliness of the oil; Connect the hydraulic motor. tunnel mucking loader Before the hydraulic motor of the belt skimming machine is put into operation, the hydraulic motor of the belt skimming machine should be separated from the working mechanism and started in no-load state, and then gradually debugged from low speed to high speed, and pay attention to no-load exhaust, and then reversed. At the same time, the shell temperature rise and noise should be checked. After the no-load operation is normal, the hydraulic motor of the scraper skimming machine should be connected with the working mechanism again after the shutdown. Then start the hydraulic motor from low to high speed load run.tunnel mucking loader.

Summary: When the hydraulic motor of the slag scraper is disassembled, first unscrew the outer ring bolt, and then screw into the screw hole on the front and back cover to remove the front and back cover. At the same time, the oil distribution shaft can be separated from the rotor body. Do not pull the oil distribution shaft, if you want to disassemble the oil distribution shaft and the back cover, just unscrew the screw; All parts are cleaned and wiped with diesel oil, coated with clean oil, not allowed to use dirty parts assembly, turn the body, oil distribution shaft, piston, steel ball friction surface and sealing groove are not allowed to have scars, dents and burrs and other defects; The seals should generally be replaced, and the surface of the seals should be coated with cleaning oil during assembly. There should be no damage to the working surface.
