Pump maintenance and troubleshooting

Problem Cause Disposal A No oil discharge

1, the direction of rotation is wrong

2, the pump did not turn

3, the pump shaft is broken, the rotor does not turn

4, the suction pipe is blocked

5, the tank filter is blocked

6, the tank filter capacity is insufficient

7, the viscosity of the oil is too high

8, the number of revolutions

9, the suction tube of poor airtight

10, the tank filter above the oil level

11, the blade can not slide out of the rotor slot

Immediately stop, correct the direction of rotation of the motor, such as any of its continued rotation will be burned damaged reasons.

Repair the coupling.

Repair the pump, confirm the number of revolutions, the pressure is above the provisions of whether the axis alignment.

Check the suction line.

Clean the filter.

Replace the larger capacity, more than twice the pump capacity.

Replace the oil and set the heater.

Specifies the number of revolutions driven.

Check the suction line.

Refueling to the level gauge.

Repair the pump. B noise large 1, suction tube small, blocked

2, the tank filter is blocked

3, the tank filter capacity is insufficient

4, the viscosity of the oil is too high

5, in the double pump, the suction pipe error

6, by the suction tube inhalation of air

7, by the pump seal at the air

8, there are bubbles in the tank

9, oil is too low

10, the leaves can not slide out from the blade slot

11, by the coupling issued a sound

12, the tank ventilation holes are blocked or the capacity is insufficient

13, more than the required number of times

14, more than the prescribed pressure

15, bearing wear

16, cam ring wear

17, the pump cover tight bad

18, pump damage inhalation vacuum should be below 200mmHg.
