The invention discloses a corrosion-resistant gasoline filter, which comprises a casing. The middle end of the bottom of the casing is provided with a dirty oil inlet, the upper end of the dirty oil inlet is provided with a threaded interface, and the inner ends of the filter cover and the casing are provided with supports. The outer end of the spring and the filter layer of polymer material is provided with filter paper, and the top of the filter cover is provided with a clear oil outlet. The inner wall of the casing is provided with a wear-resistant ceramic coating; the outer wall of the casing is provided with a Teflon coating; and a TPU layer is provided outside the Teflon coating. In the present invention, by setting a wear-resistant ceramic coating on the inner wall of the shell, the anti-corrosion ability and anti-cavitation wear performance of the filter are greatly improved, and the service life of the equipment is prolonged; the Teflon coating provided has an explosion-proof effect and can Reduce the risk of the filter cylinder bursting due to excessive fluid pressure; increase the mechanical strength and bearing capacity of the device by setting the TPU layer.
Description
technical field [0001] The invention belongs to the technical field of filters, in particular to a corrosion-resistant gasoline filter. Background technique [0002] Gasoline is as important to the gasoline pump as food is to the human body. Without the supply of gasoline, the gasoline pump cannot work. In addition, in terms of gasoline and oil products, if the oil is not very good and there are many impurities in the gasoline, it will cause huge damage to the gasoline pump, thus affecting the normal operation of the fuel system. The main function of the gasoline filter is to filter out impurities in gasoline and prevent them from entering the carburetor. At present, most engines are equipped with disposable paper filter gasoline filters, which are easily blocked by impurities in gasoline and shorten the service life; in addition, the existing air filters have poor mechanical properties, wear resistance and corrosion resistance And oil resistance can not meet the demand, r...
