| Gas-liquid supercharger high-pressure airproof characteristics and classification | Gas-liquid supercharger high-pressure airproof characteristics and classification
Pressure seal type many, according to the work principle into force since closely sealing seal and two classes. Mandatory seal is connected pieces (bolts) on the prestressing force to ensure the cover of pressure vessels, seal components and cylinder body ends with certain contact between the pressure to achieve the objective. Sealing Since the seal is closely with pressure container operating pressure increases, seal components and, at the end of the cylinder body contact pressure increases, sealing effect. The characteristics of pressure seal is closely, the higher the sealing element in the contact pressure force, sealed performance is good, the operation condition fluctuations, reliable seal still. But the structure is more complex, make more difficult. According to seal tightly sealed the element deformation can also be divided into tight seal axial and radial since since closely.
According to the seal material performance, high pressure seal and sealing devices can be divided into that of plastic deformation plastic seal, sealing components elastic deformation of elastic seal.
At present, pressure containers of seal has the following kinds:
1 there are flat mat compulsory sealing seal, taken in sealing and octagon gasket seal,
2 half since there dicone seal tightly sealed,
3 since closely sealing seal, the five DE wedge is sealed, hollow metal o-ring seals, C the o-ring seal, B ring seal, triangle, octagon gasket seal cushion seal tightly sealed, flat mat and the rubber o-ring seals, etc. |
