When the vertical sewage pump is used, it needs regular maintenance

(1) Check whether the sewage pump pipeline and joint are loose. Roll the sewage pump by hand to see if it is flexible.

(2) Add the bearing lubricating oil into the bearing body. The oil level shall be at the center line of the oil mark. The lubricating oil shall be replaced or made up in time.

(3) Unscrew the water diversion screw plug of the sewage pump body to inject water (or slurry).

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

(5) Start the motor. After the sewage pump works normally, turn over the outlet pressure gauge and the inlet vacuum pump to see if they show proper pressure. Then turn over the gate valve gradually to check the load condition of the motor together.

(6) Try to control the flow and lift of the sewage pump within the range indicated on the label, so as to ensure that the sewage pump works at the point, so as to achieve great energy saving effect.
