Reasons For Water Leakage When The Submersible Sewage Pump Has Not Been Used For A Long Time

After some users purchased the submersible sewage pump, they left it aside for a long time and did not use it for a long time. During the new installation and use, they followed the operation steps in the instruction manual. They always filled the water first and then started the pump without idling, but once the pump was started, it would There was water leakage. The water leakage of the pump that has not been used for a long time is actually caused by the reason that it has not been used for a long time. Because there is no liquid in the pump body, the rubber parts of the mechanical seal have been in contact with the atmosphere for a long time and have been oxidized, resulting in a gap between the rubber parts and the pump shaft. Adhesion reaction, before use, because the fan blade of the motor is not turned by hand to separate the rubber from the pump shaft, and the motor pulls too much at the moment of starting, causing the mechanical seal to leak due to the damage of the rubber, so here is a reminder The most important thing is that if the self-priming pump has been parked for more than one month without liquid for a long time, it is advisable to rotate the pump shaft before starting the next time. It should also be noted that submersible sewage pumps are prohibited from working without liquid. The solution is to only replace new mechanical seal components.

The reason for the water leakage of the submersible sewage pump that has not been used for a long time is only for self-priming pumps or other centrifugal pump products. If it is a sewage pump product such as a submersible sewage pump itself, the mechanical seal parts are oil-lubricated. The above conclusions can be drawn from It can be seen from the moment when the self-priming pump is filled with water. If it is a quality problem of the submersible sewage pump itself, there will be water leakage at the mechanical seal after filling.

The most common methods of water pump maintenance In agricultural production and rural daily life, water pumps are commonly used agricultural machinery by farmers, but if they are used improperly, they will often damage spare parts and cannot be used. Introduce 8 simple methods of repairing water pumps to farmers' friends

1 If there is water left in the pump and pipeline, it should be completely emptied.

2 If the water pump and pipeline are easy to disassemble, they can be dismantled and cleaned with a brush for rust. If the paint peels off, the pipe can be heated in the sun and then coated with hot cypress. It should be cleaned with clean gasoline or kerosene, but there should be no impurities such as iron filings and sand in the oil.

3 Whether the impeller 1 is cracked and corroded, and whether the fixing nut of the impeller is loose. Do not hit the pulley or coupling with a hammer when disassembling the impeller. So as not to crack or damage the bearing

4 Check the gap at the leak-reducing ring of the impeller, if the measured gap exceeds 2 times the specified value, the leak ring should be replaced

5 Remove the corrosion on the packing, and refurbish or replace the packing.

6. If the pump casing is impacted by a water hammer or the accumulated water is not released in time in winter, it can be broken. If the damage is slight, it can be repaired. 8. The pulley is cracked and the shaft hole is large.
