How to Repair the Sump Pump?

To ensure the normal operation of the sewage pump is very important, below we Sump Pump Factory to take a look at how to repair the sewage pump.

(1) Check the sewage pump pipeline and joints for looseness. Turn the sewage pump by hand to see if the sewage pump is flexible.

(2) Add bearing lubrication oil to the bearing body, observe that the oil level should be at the center line of the oil mark, and the lubricating oil should be replaced or replenished in time.

(3) Unscrew the water inlet screw plug of the pump body of the sewage pump and infuse the water (or the slurry).

(4) Close the gate valve and outlet pressure gauge of the outlet pipe and the inlet vacuum gauge.

(5) Jog the motor and check if the motor is turning correctly.

(6) Start the motor. When the sewage pump is running normally, open the outlet pressure gauge and the inlet vacuum pump, and then display the appropriate pressure, gradually open the gate valve and check the motor load.

(7) Try to control the flow and head of the Type SP Sump Pumps within the range indicated on the label to ensure that the sewage pump operates at the highest efficiency point to obtain the maximum energy saving effect.

(8) During the operation of the sewage pump, the bearing temperature should not exceed the ambient temperature of 35 °C, and the maximum temperature should not exceed 80 °C.

(9) If the Type SP Sump Pumps is found to have abnormal sound, stop immediately and check the cause.

(10) When the sewage pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.

(11) During the first month of operation, the Sewage Pump will change the lubricating oil after 100 hours, and then change the oil once every 500 hours.

(12) Regularly adjust the packing gland to ensure that the dripping in the packing chamber is normal (it is better to make a drip leak).

(13) Regularly check the wear of the bushings and replace them in time after the wear is large.

(14) When the sewage pump is used in the cold winter season, after parking, the water plug of the lower part of the pump body should be unscrewed to release the medium. Prevent freezing cracks.

(15) The Vertical Sump Pump is to be deactivated for a long time. It is necessary to disassemble the pump completely, dry the water, and apply the grease to the rotating parts and joints.
