Automobile pipeline is mainly composed of rubber pipe and metal pipe. It is responsible for the transmission of oil, water, antifreeze, gas and liquid pressure. Among them, rubber pipe has the most types and is the main part of automobile. Compared with metal pipe, automobile rubber pipe is soft, single prefabricated part and variable shape; Therefore, rubber pipes are mostly used in cooling, air conditioning and power steering lamps.
The main materials of automobile rubber hose are generally EPDM, nitrile oil resistant rubber, neoprene, fluororubber, ethylene propylene rubber, etc; Automobile rubber hose requires a wide range of ambient temperature; From -40 to +120, it should be used normally, with corrosion resistance and aging resistance. At the same time, it also has a certain hardness and tensile strength.
Although the structure of automobile rubber hose for different purposes is different, it is generally divided into three parts: inner layer, middle reinforcing layer and outer layer. The inner layer is the layer where the rubber hose directly contacts the transmission medium, which plays the role of diversion and sealing. The inner layer should have a certain thickness and be resistant to temperature and corrosion. The reinforcing layer is the part of the rubber hose under pressure and has considerable support strength; It can protect the rubber hose structure and increase the pressure resistance; The outer layer is the protective layer of rubber hose, which plays a defensive role. It should have a certain thickness, temperature resistance, corrosion resistance, friction resistance, aging resistance, etc.
