Background Knowledge：
Mechanical seal structure type of acid-resistant pump
The seal of the acid-resistant pump has eliminated the original type of sealing with packing on the pump shaft, and adopts a double  mechanical seal. The mechanical seal is mainly composed of a rotary face, a stationary seat, a spring, a shaft sleeve, a water seal, and an O-ring. In order to protect the seal against acid, a water-washing seal is adopted for flushing aim, and the flushing water can also help cut down temperature of the mechanical seal during operation, which greatly prolongs the service life of the equipment.
