1. After the Submersible borehole pump for 4 inch is closed, put all the remaining water into the pump and pipeline, and clean the external soil to avoid freezing the water and ice in the pump body and the water pipe, causing them to expand and crack.
2. The bottom valve, elbow and other cast iron parts of Submersible borehole pump for 4 inch should be brushed with steel wire, then coated with anti-rust paint, then painted, dried, and placed in the machine room or storage room for ventilation and dry storage.
3. After the belt is removed, wash and dry it with warm water, hang it in a dry place without direct sunlight, and don't store it in a place with oil, corrosion or smoke. In any case, do not dip in oil, do not apply rosin and sticky substances.
4. Check the ball bearings, such as inner wear, movement, ball wear or surface spots. The gasoline or kerosene available for cleaning the bearings does not need to be replaced, greased and refilled.
5. Check whether the pump impeller has cracks or holes, whether the impeller fixing nut is loose, if it is damaged, repair or replace it. If the impeller is excessively worn or damaged, it should generally be replaced with a new one. Local damage can be repaired by welding, and the impeller can be repaired with epoxy mortar. The repaired impeller is generally subjected to a static balance test. Check the gap at the wear ring of the impeller. If it exceeds the specified value, repair or replace it.
