The Material Of The Gasket
Jun 21, 2017


Washers are widely used in the bearing and non-bearing structures of general mechanical products. They are characterized by low cost, easy installation and suitable for frequent parts of assembly and disassembly. But the spring washers are very low anti-loose ability! Especially in the current European and American countries require high reliability products in the adoption rate is very low, especially the important bearing structure of the connection site has long been abandoned for many years.

The role of the gasket - Increases the support area of the joint to reduce the pressure at the contact and avoid the surface of the joint when the nut is tightened.

Seals There are many kinds of gaskets, different materials and different types of different applications and installation are different, letter fasteners will now be the role of several gaskets and installation notes introduced to everyone, we must pay attention to see Oh.

Copper flat pad

Copper flat mat material is generally copper material, mostly used in the larger parts of the pressure, Seals such as the nozzle of the gasket.

Paper Pad

There are two uses for it. One is to increase the sealing, to prevent oil spills; the second is used to adjust the gap between components. The use of paper pad parts can not be arbitrarily increase or decrease, such as the diesel pump between the side of the pad is used to adjust the fuel time, the gasket thickness of 0.1 mm, the gasket for each 0.1 mm, flywheel oil supply angle corresponding Change 1.7 degrees. The axial clearance between the crankshaft and the crankshaft is also achieved by adjusting the pad between the side cap and the body of the flywheel end. If the damage should be timely replacement, Seals to prevent the occurrence of oil spills.

Spring pad

The spring pad is used for the connection of the bolts to prevent the bolts and nuts from being released by the shock. Seals In particular, it is difficult to see or not easy to operate the part of the bolt should use the spring pad.

Asbestos pad

Seals Asbestos pad with high temperature characteristics, so the use of its parts are high temperature parts, such as exhaust pipe and cylinder head between these parts can not use other gasket instead.

Flat pad

Its role is through the flat pad of the nut pressure evenly distributed in the compression parts, while protecting the bolt thread and the surface of the connector. The general thin metal shell is fixed with metal flat pad.
