The basic requirements for mechanical seal design:

Generally, the design requirements for mechanical seals are:

(1) Tightness: It is required to determine the allowable leakage, leakage point, leakage direction, etc., to ensure safe and reliable operation of production;

(2) Reliability: Expressed by service life. Reflect the comprehensive results of sealing wear parts, corrosion resistance, temperature resistance and vibration resistance. For petrochemical enterprises, long life of pump shaft seals are required to ensure continuous production of process equipment;

(3) Stability: The mechanical seal can still ensure normal function when the working parameters are changed in the running state;

(4) Restrictions on external dimensions and structural conditions;

(5) Save energy and material consumption;

(6) Materials and prices.
