What are the reasons for water leakage in the filler of the mud purification system?

The dimensions of the extended parts at both ends of the mud pump accessory transmission shaft are completely symmetrical, and large pulleys or sprockets can be installed at both ends.
The dimensions of the extended parts at both ends of the mud pump accessory transmission shaft are completely symmetrical, and large pulleys or sprockets can be installed at both ends. The supporting bearings at both ends adopt single row radial short cylindrical roller bearings. The deterioration of the mud pump accessory packing is one of the main reasons for excessive water seepage and short service life of the pump packing. In addition, the reasons for failure include loss of elasticity and poor packing quality. Among many fillers, asbestos fillers are currently relatively widely used. After drying thoroughly and hardening, blocky phenomena will form. The accessories of the mud pump will increase the contact area between the pump shaft and the pump shaft, reduce pressure, and increase wear. The following is a specific introduction to the causes of water pump packing leakage.
The filling replacement cycle is too long, resulting in aging of the filling material; The packaging quality is poor, the structure is loose, easy to wear and tear, and it is unqualified. These are the reasons for the leakage of the mud pump accessory packing, and at this time, the packaging needs to be replaced. In addition, during the operation of the pump, if the packing gland is too tight, the packing will fill the pump shaft, causing water in the water seal ring to not pass smoothly, which will cause the packing to fail due to overheating and hardening.
Due to insufficient cooling and lubrication, the mud pump accessories should be tightened with the packing gland until the water flows out dropwise. The inner ring of the water seal ring of the mud pump accessory is too small, the number of small holes on the ring is insufficient or blocked, the installation position of the water seal ring is incorrect, and the water seal pipe is blocked; The small gap between the packing gland and the pump shaft can also cause water leakage in the pump packing. Filling is an important component of mud pump accessories, and its normal operation is closely related to filling. Therefore, during daily use, check frequently.
The above is the summary of the editor, hoping to be helpful to you.
