Sealing element

The sealing function of mechanical equipment is to prevent leakage. The parts that play the role of sealing are called seals, which are called seals for short. Seal is one of the most widely used parts in mechanical products. In the production, processing, storage, transportation and even sales of petroleum, petrochemical and chemical industries, there are often flammable, explosive, high temperature, high pressure, toxic and harmful, corrosion and other risk factors. The "dripping and leaking" of the working medium and lubricating oil of the machine and equipment used has caused great harm to the production.

Leakage of working medium or lubricant in the equipment will cause waste and pollute the environment. In general, it is difficult to recover the substances leaked into the environment, which seriously pollutes the air, water and soil. For example, many chemical plants have bad smell and smoke, which cause serious pollution to the environment and seriously harm the health of workers; the leakage of inflammable, explosive, highly toxic, corrosive and radioactive substances may cause fire, explosion, poisoning and other accidents, leading to plant damage or even death, which may endanger the safety of personnel and equipment: gas, dust, water, etc. enter the mechanical equipment in the environment Standby will lead to premature wear and discard of bearings, gears, etc. Mixing into chemical plants will affect the purity of chemical products; internal leakage of fluid machinery will affect volume efficiency, etc. With the development of large-scale production equipment, the production process towards high temperature, high pressure, high-speed development, more and more opportunities for leakage, more and more serious risk of accidents, economic losses are also more and more serious. In general, leakage of pipes or equipment may cause shutdown of a group of equipment or even the whole plant, and may also cause fire, explosion, casualties and other major accidents. Therefore, sealing performance has become an important index to evaluate the quality of mechanical products.

Common seals include mechanical seal, hydraulic and pneumatic seal, gasket seal, packing seal, rubber seal, labyrinth seal, spiral seal, magnetic fluid seal, high pressure seal, etc.
