Classification of mechanical seals

According to the rotation or static of the spring element, it can be divided into: a rotary internal flow unbalanced single-end seal, referred to as a rotary type; a static external flow internal balance type single-end seal, referred to as a static type.

The static ring is located inside or outside the sealing end face and can be divided into: built-in type and exterior type.

According to the leakage direction of the sealing medium, it can be divided into: internal loss and outflow type.

According to the unloading situation caused by the media on the end face, it can be divided into: balanced and unbalanced.

According to the logarithm of the sealing end face, it can be divided into: single end and double end.

According to the number of springs, it can be divided into: single spring type and multi spring type.

Classified by elastic elements: spring compression and bellows.

Classified according to non-contact mechanical seal structure: hydrostatic type, fluid dynamic pressure type, dry gas sealed type.

Classified according to the temperature of the sealed chamber: high, medium, ordinary, low temperature seal.

Separated according to the pressure of the sealed chamber: ultra high, high, medium and low pressure mechanical seals.
