Description

technical field

[0001] The invention belongs to the field of filters, and in particular relates to a detachable spin-on filter and a method for filtering fluid thereof. Background technique

[0002] The spin-on filter is a type of filter developed in the 1970s with filter paper as the filter material. The spin-on filter is compact in structure, light in weight, reliable in use, and convenient in maintenance. It is widely used in engines and hydraulic pressure on the system. According to the incomplete statistics of existing data, more than 90% of the spin-on filters are used on automobile engines, and more than 80% of them are used on construction machinery engines.

[0003] But the spin-on filter also has obvious defects, such as figure 1 As shown, the spin-on filter generally includes a sealing ring 1, a threaded cover plate 2, a filter housing 3, a filter element 4 and a spring 5, and the filter element 4 includes an inner frame 42, a bypass valve 43, a filter material ...
