Maintenance method of hydraulic motor of multi-function slip loader

[DIG-DOG]

There is no need to set the control oil when the multi-function slip loader brake is switched on and off. When the inlet pressure of the hydraulic motor is higher than the opening pressure of the brake, the skid loaderbrake will automatically open, and when the inlet pressure of the hydraulic motor is lower than the opening pressure of the automatic brake. The hydraulic braking pressure of the motor is 18%~25%, the rated pressure range is adjustable, and the braking torque changes accordingly. Specific requirements can be specified in the order contract, static and dynamic braking torque is less than 10%. The pickling pipe and pipe joints connected to the motor are generally analyzed and require pressure flushing of the pipe before connecting the pipe to the motor. The specific measures are as follows: First, put the motor into and take out the tubing (directly connected to the motor, not connected);

Start the pump and reversing valve to circulate the hydraulic oil of the multi-function loaderon the line for 10 to 15 minutes. The purpose is to directly transport the impurities in the pipeline and valve to the oil, and then store the oil, clean the tank, and ensure the cleanliness of the oil. Load up the hydraulic motor. It is concluded that before the hydraulic motor starts to operate, it should start from the working mechanism, and then from low speed to high speed, and then deal with the air and exhaust, and then reverse. At the same time, check whether the temperature rise and noise of the housing are normal. After the no-load operation is normal, the hydraulic motor is re-connected to the working mechanism, and then the hydraulic motor is transferred from low speed to high speed.

The use of hydraulic oil for multi-function slip loadershould select different types of oil according to the working speed, working pressure and working temperature. Generally, 46 kinds of anti-wear hydraulic oil (or similar oil) are recommended. When the working speed is low, the oil temperature is high, and the oil with higher viscosity can be selected; When the working speed is high and the oil temperature is low, the oil with lower viscosity can be selected. For the newly installed multi-function slip loader hydraulic motor system, the working oil should be replaced after 2 to 3 months, according to the use and working conditions, every 1 to 2 years. The hydraulic motor system can not suck air, otherwise the hydraulic motor does not run smoothly, will produce noise and vibration. Slip loadermanufacturers summarized the removal of the hydraulic motor, first unscrew the outer ring bolt, and then unscrew the screw holes on the front and back covers, remove the front and back covers, and separate the oil distribution shaft from the turntable.
