Test operation (only for closed system):
Oil replenishment pressure measurement: directly turn on the motor speed to 1000
rpm. Note: observe the leakage flowmeter. After the value is stable, this value is the oil
replenishment flow; Increase the loading pressure until the value is stable, which is the
opening pressure of the overflow valve of the makeup oil pump; After the test, reduce the
loading pressure to zero and set the speed control knob to zero,.

2、 Tests; Closed pump test
1.
1.
Start the oil supply motor
2.
2.
Turn the above impact switch to the normally on state and conduct impact test in the
opposite direction.
3.
3.
Adjust the low-pressure oil supply pressure control knob (it is necessary to adjust the
loading pressure control knob at the same time) to adjust the oil supply pressure to
1.5~2mpa;
4.
4.
Start the main motor and adjust the speed control knob to make the speed reach
800~1800 rpm;
5.
5.
During the above second and third operations, pay attention to observe the driving
tachometer, right flow meter and right loading pressure gauge (this gauge is adjusted to
2~3 MPa). The value of the oil supply pressure gauge is not less than 1.5 MPa, so that
the speed stays at a fixed value and recorded
