I. The Importance of Mechanical Seals

Mechanical seals, composed of a rotating ring, a stationary ring, and a spring, are crucial for pump operation. They prevent liquid leakage and air ingress during pump operation, ensuring normal function and efficiency. Mechanical seal failure can lead to pump breakdowns, environmental pollution, and safety hazards.

II. Principle of Plan 11 Flushing Plan

Plan 11 is a flushing method that uses the pump's own fluid. It diverts high - pressure fluid from the pump's outlet, filters and regulates it, and then directs it into the seal chamber. This fluid flow removes heat and impurities generated during operation, reducing seal face temperature and wear, thus enhancing reliability and service life.
         

III. Applications of Plan 11 Flushing Plan

Plan 11 is widely used in various industries, including chemical, petroleum, paper - making, municipal water supply and sewage treatment, and power generation.

IV. Components and Installation of Plan 11 Flushing Plan

Plan 11 mainly consists of
- A flushing liquid supply system, which sources fluid from the pump's outlet.
- A filter, which removes impurities from the flushing liquid to prevent seal damage.
- Connection pipes, which transport the flushing liquid to the seal chamber.

V. Advantages of Plan 11 Flushing Plan

- Simple structure Using the pump's own fluid eliminates the need for extra supply equipment.
- Low cost No additional supply devices or complex control systems reduce initial investment.
- Easy maintenance Fewer components and accessible installation location facilitate inspection and cleaning.
- It effectively lowers seal temperature, reduces wear, and improves seal reliability and lifespan.
