Reasons and solutions for leakage of sewage pump

It is a common sewage pump sewage pump, using a wide range, sewage pump out the cause of leakage current was mainly due to seal wear and tear or due to aging, when this happens can be replaced with new seals or take the following Ways to solve.

First, the rubber seal in the nylon seal seat is worn. The seal can be taken out and then replaced. If the fastening spring on the seal ring loses elasticity or breaks, the spring can be removed and the wire can be removed with a suitable diameter wire or iron wire. tight.

Second, the sewage pump seal ring due to long-term use of loss of elasticity, then remove the seal ring, and then find a piece of paper from 0.3 to 0.5 millimeters thick or cut into a slightly larger pad than the original seal into the groove Finally, the original seal is fitted.

Third, the oil hole rubber seal damage, you can find a piece of tape, cut into a hole slightly larger than the bolt, the top plus a flat pad, together in the bolt into the oil hole.

4. The elasticity between the seal box and the cast iron loses its elasticity. The seal ring can be taken out from the cast iron groove, and a piece of hard paperboard with a thickness of 0.6 to 1 mm can be cut into the same size, and then it is placed in the groove and then sealed. Put in the circle.

Fifth, the first seal ring can be worn out to remove the nylon seal ring, then coated with butter asbestos rope, wrapped in stainless steel sleeve to fill slightly higher than the original nylon seat, and then filled with butter, and then press the nylon seat with a bolt Compaction.
Leakage of submersible sewage pump is mostly caused by mechanical seal problems. To make the pump work stably and reliably, it is necessary to carefully calculate the working pressure of the pump and consider the influence of the pipeline during the selection. Pay attention to the temperature, physical and Chemical properties. The operation specification must be followed during use to avoid malfunctions caused by misoperations. During operation, it must be checked and problems must be discovered in a timely manner. Care must be taken to repair and assemble, pay attention to the elasticity of the spring, 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.
