AI Technical Summary

Problems solved by technology

The current filter element is generally formed by placing a filter screen between the supporting frame and the protective frame at one time, because when the plastic frame shrinks due to thermoforming, it will shrink with the filter screen, and the filter screen will be in a wrinkled state after shrinking
This kind of filter element is used as an automatic filter. Two-way filtration will cause the pressure of the pump oil to drop, and also affect its power effect.

Embodiment Construction

[0010] In the processing technology of the fuel filter element of the present invention, the fuel filter element includes a support frame, a protection frame 1 and a filter screen 5, and the end of the support frame is provided with a concave groove 2 to connect the filter screen 5 After being sleeved on the support frame, the protective frame 1 is connected to the support frame by injection molding, so that the filter screen 5 sinks into the groove 2 to form an integral filter element with a flat screen surface. The supporting frame is composed of a main body 3 and a radiating plate 4, the radiating plates 4 are evenly distributed on the main body 3, and the concave groove 2 is provided at the end of the radiating plate 4. When injection molding is performed on the groove 2, the filter screen 5 is simultaneously plunged into the groove 2, and the filter screen 5 is tightened. Without wrinkles, the pressure of the oil pump is not reduced due to the wrinkles of the filter screen...

Abstract

The invention discloses a processing process of a fuel filter element. The fuel filter element comprises a support frame, a protection frame and a filter screen and is characterized in that concave grooves are formed in the end parts of the support frame; and after the filter screen is mounted on the support frame in a sleeving manner, the protection frame is connected with the support frame by adopting an injection molding method, and the filter screen is clamped in the grooves, so as to form the integrated filter element. The processing process of the fuel filter element has the benefits asfollows: the integrated filter element with a smooth net surface is formed, the filter screen is prevented from wrinkling, remains durable and keeps a good filtering function.

Description

Technical field [0001] The invention relates to a processing technology of a fuel filter element. Background technique [0002] The fuel of the internal combustion engine must be filtered before it can be used, so the filter element is a very critical component of the internal combustion engine. The current filter element is generally formed by placing a filter between the support frame and the protection frame at one time. Because the plastic frame shrinks due to thermoforming, it will shrink with the filter. After the filter shrinks, it will be in a fold state. This kind of filter element used as an automatic filter for two-way filtration will cause the pump oil pressure to drop and also affect its power effect. Summary of the invention [0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a fuel filter element with a simple processing technology so that the filter element can be durable.
