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
The present invention relates to a kind of filter, relate in particular to a kind of oil strainer.
Background technique
Be applied in the oil strainer of special occasions, be installed on fuel tank internal as oil pump, all be immersed in hydraulic oil, and do not have in the situation of oil inlet pipe, due to the filler opening position of the oil outlet of hydraulic system and oil pump with approach, undercurrent is told in existence, and therefore, hydraulic oil is not steady, fluctuation is large, cause the oil pump oil absorption unstable, vacuum degree deficiency, noise strengthens.Therefore, should provide a kind of new technological scheme to address the above problem.
Summary of the invention
Purpose of the present invention: for above-mentioned deficiency, provide a kind of simple in structure, hydraulic fluid flow rate is allocated surely very much, the oil purifier that noise is little.
For achieving the above object, the technical solution used in the present invention is: oil strainer, comprise housing, described enclosure interior is fixed with some metafiltration nets, the center line of described housing is provided with hush pipe, and stretch out outside housing the upper end of described hush pipe, and its end is oil outlet, the bottom of described hush pipe is fixed on housing, is symmetrically arranged with filler opening on the tube wall of the hush pipe in described housing.
The quantity of described filler opening is 8.
The bottom of described hush pipe is connected on housing.
Oil strainer of the present invention, be provided with hush pipe in enclosure interior, be symmetrically arranged with a plurality of filler openings on hush pipe, when hydraulic oil filters by filter screen the position that arrives hush pipe, hush pipe destroys undercurrent, stablize flow velocity, when hydraulic oil enters the relative filler opening of hush pipe and arrives hush pipe inside, the flow region of hydraulic oil is constant, steadily enters oil pump.According to quality and the requirement of the oil that will filter, can adjust the quantity of filter screen, to guarantee filter precision.
Advantage of the present invention is: simple in structure, have the effect of noise reduction, and its amount of abating the noise can reach 50%.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, housing, 2, filter screen, 3, hush pipe, 4, oil outlet, 5, filler opening.
Embodiment
As shown in Figure 1, oil strainer of the present invention, comprise housing 1, housing 1 inside is fixed with some metafiltration nets 2, and the center line of housing 1 is provided with hush pipe 3, stretch out outside housing 1 upper end of hush pipe 3, and its end is oil outlet 4, and the bottom of hush pipe 3 is fixed on housing 1, is symmetrically arranged with filler opening 5 on the tube wall of the hush pipe in housing 1, the quantity of filler opening 5 is 8, and the bottom of hush pipe 3 is connected on housing 1.
Oil strainer of the present invention, be provided with hush pipe 3 in housing 1 inside, be symmetrically arranged with a plurality of filler openings 5 on hush pipe 3, when hydraulic oil filters by filter screen 2 position that arrives hush pipe 3, hush pipe 3 destroys undercurrents, stablize flow velocity, when hydraulic oil enters the relative filler opening of hush pipe 35 and arrives hush pipe 3 inside, the flow region of hydraulic oil is constant, steadily enters oil pump.According to quality and the requirement of the oil that will filter, can adjust the quantity of filter screen 2, to guarantee filter precision.
