Reinforced fluororubber diaphragm for oil-gas separation system

Abstract

The invention relates to the technical field of automotive engine lubricating systems, in particular to a reinforced fluororubber diaphragm for an oil-gas separation system. The reinforced fluororubber diaphragm comprises woven fabric, a high-low temperature resistant fluororubber diaphragm body and a plastic connecting rod, and is characterized in that the upper end of the plastic connecting rodand the high-low temperature resistant fluororubber diaphragm body are subject to one-step vulcanization forming through an adhesive; the lower surface of the woven fabric subject to surface activation treatment and the high-low temperature resistant fluororubber diaphragm body are integrally formed; and aromatic polyamide resin woven fabric subject to surface silanization treatment serves as theabove woven fabric. By adoption of the reinforced fluororubber diaphragm provided by the invention, the problem that a conventional diaphragm with a pure rubber substrate is easy to corrode and crackcan be solved; the provided reinforced fluororubber diaphragm crankcase can serve as a crankcase ventilation valve diaphragm which is reinforced, resistant to high and low temperature, resistant to corrosion, and used in the oil-gas separation system; and the tensile and anti-tearing properties of the reinforced fluororubber diaphragm can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile engine lubricating systems, in particular to a diaphragm for a reinforced fluororubber oil-gas separation system. Background technique [0002] The oil-air separator for automobiles is a very important part in the engine lubrication system. Its main function is to separate the engine oil from the gas discharged from the crankcase, reduce the discharge of engine oil from the breathing port of the crankcase to the outside of the engine, avoid oil loss, and ensure the lubricating performance of the engine oil. ; At the same time, the acidic substances in the exhaust gas are also separated to avoid backflow into the engine and cause corrosion to the moving parts of the engine. [0003] As an important part of the oil-gas separation system, the crankcase ventilation valve diaphragm not only has to withstand high temperature and high pressure environment, but also resists the corrosion of the rubber ...

AI Technical Summary

Problems solved by technology

The diaphragm of the pure rubber matrix is ​​easy to corrode and crack during use, which affects the normal use of the oil-gas separator, resulting in insufficient oil-gas separation, which eventually leads to a decrease in the lubricating performance of the engine oil, affects the service life of the engine, and increases environmental pollution.
