Large size seal: what is the seal?

According to the manufacturer of large-size seal, the seal indicates tight closure. Sealing can be divided into static sealing and dynamic sealing. 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 invading the interior of the machine equipment. Quiet means that the sealed container is tightly sealed in the sealed compartment in order to seal the seal of the letter and the will.

  Large size sealAccording to the manufacturer, sealing means tight closing. Sealing can be divided into static sealing and dynamic sealing.

Quiet means that the sealed container is tightly sealed in the sealed compartment in order to seal the seal of the letter and the will.

  Large size seal manufacturers said,Sealing electrostatic sealing mainly pad sealing, sealing glue sealing, direct contact sealing. According to the working pressure, static seal can be divided into low pressure static seal and high pressure static seal. The commonly used material for medium and low pressure static seals is a softer and wider gasket seal, and a harder material is used for high pressure static seals to contact a narrower metal gasket. Seal seal can be divided into rotary seal and reciprocating seal two basic types. According to whether other sealing parts are in contact with relative moving parts, it can be divided into contact type seal and non-contact type seal. According to the sealing piece and contact position, it can be divided into round seal and end face seal. End face seal is also called mechanical seal. The centrifugal seal and spiral seal in the dynamic seal are used to provide power to the medium so that it can be sealed when the machine is running, so it is sometimes called dynamic seal.

Device Type:

1. Press forming

This molding method is suitable for most rubber sealing parts, such as various extrusion seals, rotating shaft lip seals, reciprocating lip seals, rubber seals, film seals, bellows seals, etc.

2. Processing and forming

Such as rectangular seal, piston ring seal, coaxial seal (or slip ring combination seal), etc.

3. Plate or strip material

  Large size seal manufacturers said,For example, rubber, fiber-reinforced rubber, bonded asbestos fiber, aramid fiber, etc. Plate or strip materials are mostly used for sealing gaskets or fillers, and rubber is used as an adhesive for asbestos and its substitutes. Among them, aramid fiber and processed rubber rings are sometimes used for reciprocating sealing of aerospace equipment.
