Washer is a small part used between the connector and the nut. Generally, flat metal rings are mainly used. Although it is small, it protects the surface of the connector from scratches by the nut, and dispersing the pressure on the connector depends entirely on it.
Copper leather asbestos pad
Copper-leather asbestos pads are characterized by high pressure and high temperature resistance, and they are used for engine cylinder pads. Before use, the copper-leather asbestos pad must first be removed from dirt or dust on the joint surface. Note that the flange of the copper-leather side should face the cylinder head to prevent air leakage from being installed. Do not fold hard during installation, and should be kept intact and sufficient elasticity.
Paper pad
It has two uses. First, increase sealing and prevent oil leakage; second, adjust the gap between components. The axial clearance between the crankshaft and the crankshaft is also achieved by adjusting the paper pad between the side cover at the end of the flywheel and the body. If the paper pad is damaged, replace it in time to prevent oil leakage.
Flat mat
Its function is to divide the pressure of the nut evenly on the pressure receiving part through a flat pad, while protecting the bolt thread and the surface of the connector. Generally, thin metal shells are fixed with metal flat pads.
Aluminum flat pad
Aluminum flat pads have a certain toughness and can be used at the connections of diesel and oil pipelines. Before installation, check whether there are dents or cracks on the plane, otherwise air will be sucked in the oil leakage pipe, which will not only cause waste of oil, but may also cause burning the tiles and holding the shaft due to insufficient oil supply.
Copper flat pad
The material of copper flat pads is generally made of copper, and is mostly used in areas with higher pressure, such as gaskets of fuel injectors.
Spring pad
Spring pads are used to connect bolts to prevent bolts and nuts from being loosened due to shock. Especially for bolts that are not easy to see and are not easy to operate, spring pads should be used.
Asbestos mat
Asbestos pads are characterized by high temperature resistance, so the components used are all high temperature parts. For example, between the exhaust pipe and the cylinder head, the function of the asbestos pad is irreplaceable.
Rubber pad
It should be noted when using rubber pads that oil-resistant rubber pads can replace non-oil-resistant rubber pads, while non-oil-resistant rubber pads cannot be used instead of oil-resistant rubber pads. If it is found that it has hardened and lost elasticity, it should be replaced in time to avoid wear of the parts.
