The submersible wastewater pump is a common sewage pump. The following introduces the failure causes and solutions of the submersible wastewater pump.

The submersible wastewater pump is a common sewage pump with a wide range of use. The main reason for the leakage of the submersible wastewater pump is the wear or aging of the sealing device. When this happens, you can replace the new seal or take the following measures Several ways to solve this.

1. If the rubber sealing ring in the nylon sealing seat is worn, the sealing ring can be taken out and installed in another position. If the tightening spring on the sealing ring loses its elasticity or breaks, the spring can be removed and tied with a steel wire or iron wire of an appropriate diameter. tight.

2. If the rubber sealing ring of the oil hole is damaged, you can find a piece of tape, cut it into a hole slightly larger than the bolt, add a flat washer to it, and put it in the oil inlet hole of the bolt together.

3. The sealing ring of the submersible wastewater pump loses its elasticity due to long-term use. At this time, the sealing ring can be taken out, and then find a piece of paper or cloth with a thickness of 0.3 to 0.5 mm and cut it into a pad slightly larger than the original sealing ring and fit it into the groove, and install the original sealing ring at the end.

4. If the sealing ring is seriously worn, take out the nylon sealing ring, then coat the asbestos rope with butter, wrap it around the stainless steel sleeve and fill it to a slightly higher level than the original nylon seat, then fill it with butter, and then compress the nylon seat with bolts.

5. The sealing ring between the sealing box and the cast iron loses its elasticity. Take the sealing ring out of the cast iron groove, find a piece of cardboard shell with a thickness of 0.6 to 1 mm and cut it into the same size, put it in the groove, and then seal it. circle in.

The leakage of the submersible wastewater pump is mostly caused by the problem of the mechanical seal. In order to make the pump work stably and reliably, the working pressure of the pump must be carefully calculated and the influence of the pipeline must be considered when selecting the model. Pay attention to the temperature, and physical and chemical properties. In use, it is necessary to follow the operating specifications to avoid failures caused by misoperation and to check frequently during operation to find problems in time. Careful maintenance and assembly, pay attention to the tightness of the spring, and dynamic and static ring seals. Only in this way can the service life of the pump be extended, leakage and maintenance can be reduced, and normal production can be guaranteed.
