Problems solved by technology

[0002] Oil filters used in special occasions, such as the oil pump installed inside the oil tank, all immersed in the hydraulic oil, and there is no oil inlet pipe, due to the position and proximity of the oil outlet of the hydraulic system and the oil inlet of the oil pump, there is a warning Undercurrent, therefore, the hydraulic oil is unstable and fluctuates greatly, resulting in unstable oil absorption of the oil pump, insufficient vacuum, and increased noise

Embodiment Construction

[0012] like figure 1 As shown, the oil filter of the present invention includes a housing 1, several layers of filter screens 2 are fixed inside the housing 1, a silencer pipe 3 is arranged on the center line of the housing 1, and the upper end of the silencer pipe 3 extends out of the housing 1. And its end is an oil outlet 4, the bottom of the silencer pipe 3 is fixed on the housing 1, and the pipe wall of the silencer pipe in the housing 1 is symmetrically provided with oil inlets 5, and the number of oil inlets 5 is 8 , the bottom of the muffler pipe 3 is clamped on the housing 1 .

[0013] The oil filter of the present invention is provided with a silencer pipe 3 inside the housing 1, and a plurality of oil inlets 5 are symmetrically arranged on the silencer pipe 3. When the hydraulic oil is filtered through the filter screen 2 and reaches the position of the silencer pipe 3, the silencer pipe 3. Destroy the undercurrent and stabilize the flow rate. When the hydraulic oi...

Abstract

The invention discloses an oil filter comprising a shell. A plurality of layers of filter screens are fixed in the shell. The oil filter is characterized in that a muffling pipe is arranged on a center line of the shell, the upper end of the muffling pipe extends out of the shell and is provided with an oil outlet, the bottom of the muffling pipe is fixed on the shell, and oil inlets are symmetrically arranged on the wall of the muffling pipe in the shell. The oil filter has the advantages of simple structure and muffling function, and noise can be muffled by 50%.

Description

technical field [0001] The invention relates to a filter, in particular to an oil filter. Background technique [0002] Oil filters used in special occasions, such as the oil pump installed inside the oil tank, all immersed in the hydraulic oil, and there is no oil inlet pipe, due to the position and proximity of the oil outlet of the hydraulic system and the oil inlet of the oil pump, there is a warning Undercurrent, therefore, the hydraulic oil is unstable and fluctuates greatly, resulting in unstable oil absorption of the oil pump, insufficient vacuum, and increased noise. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an oil filter with simple structure, stable and stable flow of hydraulic oil and low noise in view of the above shortcomings. [0004] In order to achieve the above object, the technical solution adopted by the present invention i...
