1) pre test preparation.
A hydraulic oil temperature is (50+5) C. let the running motor turn and heat.
B allows the engine to stably extinguish and press the vent valve at the top of the hydraulic tank to release the remaining pressure.
C dismantled the exhaust pipe of the walking motor at the upper side of the walking table, and installed the screw plug (ST6637) to the end of the exhaust pipe of the walking motor, and then the exhaust hose (3/4-16UN) used for the test was connected to the motor oil port.
D. selects the following switch positions:
Engine control dial: fast and slow car
E mode switch: OFF
HP mode switch: OFF
Mode selection switch: general use
Automatic slow car switch: OFF.
2) detection of the oil discharge of the walking motor.
A the amount of oil that is rotated by the walking motor.
1. Lift up one side track, use wood blocks to start the engine.
(2) push the walking joystick to the full stroke position to turn the raised track. When the speed of the track reaches a constant maximum speed, it begins to measure the oil discharge of the motor. The measurement time is above 45s.
(III) at least 3 repeated measurements in two directions of forward and backward and calculate the average value.
B the amount of oil discharge during the overflow of the motor motor.
(1) the side track should be held up with one object, such as wood block, so that the track can not be rotated.
Start the engine, push the walking joystick to the full stroke position and keep it. When the oil is discharged from the hose, the oil discharge measurement begins to be carried out, and the measurement time should be above 45s.
C was measured at least 3 times in advance and backward in two directions and the average value was obtained.
