Mechanical seal industry overview

1. General situation of mechanical seal industry

1. Mechanical seal

Sealing is a component or measure that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from intruding into the interior of the machine. Seals can be divided into static seals and dynamic seals. Seals with no relative movement or relatively static joint surfaces are called static seals, and seals with joint surfaces that move relative to each other are called dynamic seals. Dynamic seals are divided into reciprocating shaft seals and rotary shaft seals according to the movement of moving parts relative to the body; according to whether there is a gap on the sealing surface, they are further divided into contact seals and non-contact seals.



2. Mechanical face seal

Mechanical end face seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation, under the action of fluid pressure, the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of auxiliary seals to keep fit and slide relative to each other. As one of the most critical core components of various types of rotating equipment, mechanical face seals are an indispensable part of the operation of rotating equipment and play a vital role in the safe operation of the equipment. Failure of seals will not only lead to production paralysis, but also may cause serious safety production and environmental protection accidents.




2. Industrial chain of mechanical seal industry

The upstream industry of mechanical seals is metal, rubber, plastic, graphite and other materials and their products and instrumentation manufacturing, and the downstream industry includes compressors, pumps, kettles and other rotating machinery manufacturing industries that transport or stir fluids. With the continuous deepening of the development of downstream industries, large-scale, large-scale, environmentally friendly, integrated, high-parameterization, and intelligent features have become the development characteristics of future equipment. The demand for high-end mechanical seals with stability and long life is increasing, which will promote the mechanical seal industry to increase technology research and development and enhance independent innovation capabilities.
