Misunderstandings During Maintenance of Slurry Pump Machine Seal

The following are several common misunderstandings during the maintenance of the mechanical seal of the slurry pump.

The greater the spring pressure, the better the sealing effect. Although no leakage will occur during the trial operation, with high-speed continuous operation, the spring compression will be too large, which will cause the friction pair to wear rapidly or even burn out instantly. Excessive compression will cause the spring to lose The ability to adjust the end face of the moving ring can lead to seal failure or directly lead to the scrapping of the spring.

The tighter the dynamic ring sealing ring, the better. In fact, too tight the dynamic ring sealing ring is harmful and useless. It not only aggravates the wear between the sealing ring and the shaft sleeve (shaft), but also increases the resistance to the axial adjustment and movement of the dynamic ring. When the working conditions change frequently, Failure to adjust in a timely manner may lead to over-fatigue damage to the spring, deformation of the dynamic ring seal, causing leakage and affecting the sealing effect.

The tighter the static ring seal, the better. The static ring seal is basically in a static state. The sealing effect will be better when it is relatively tight, but too tight is also harmful: first, it will cause excessive deformation of the static ring seal, affecting the sealing effect; The ring material is mostly graphite, which is generally brittle and can easily cause fragmentation due to excessive stress. Third, it is difficult to install and disassemble, and the static ring can easily be damaged.
