The deterioration of the mud pump packing is one of the main reasons for the water leakage of the pump packing and the short service life. In addition, the causes of the failure include loss of elasticity and poor quality of the packing.

Among the many fillers, asbestos filler is a kind of filler which is widely used at present. After dry hardening, it will form a hard block. The mud pump will make the contact area with the pump shaft greatly. Reduce, increase wear, the following is a specific introduction to the cause of water leakage of the pump filler.

The filler replacement cycle is too long, the filler ages; the filler quality is poor, the structure is loose, and the wear and tear are easy to cause the mud pump filler to leak water. At this time, the filler needs to be replaced.

In addition, during the operation of the pump, if the packing gland is too tight, the packing of the pump shaft causes the water of the water sealing ring to pass through, resulting in failure of the packing due to insufficient cooling and lubrication. Phenomenon, at this time, the mud pump should tighten the packing gland until the water flows out by drop.

The inner ring of the water seal ring of the mud pump is too small, the number of small holes on the ring is insufficient or blocked, the installation position of the water seal ring is not correct, and the water seal pipe is blocked; the gap between the packing gland and the pump shaft is too small, etc. The cause of the leak. Filler is an important part of the mud pump. Whether it can operate normally has a great relationship with the filler. Therefore, it must be checked frequently during daily use.
