Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figures 1 and 2：Present embodiment discloses a kind of hydraulic oil container purification devices, for in hydraulic oil container 1
Oil product is purified, and 1 upper end of hydraulic oil container is equipped with fuel sucking pipe 11, and the upper surface of hydraulic oil container 1 is equipped with filter core 5, the lower end of filter core 5
It is connected to the upper end of fuel sucking pipe 11, the upper surface of hydraulic oil container 1 is also connected by screw to upper cover 2, and 2 upper end of upper cover is equipped with several
Upper cap bore 21, upper 21 connecting branch road 4 of cap bore, the other end of bye-pass 4 connect main pipe rail 41, and main pipe rail 41 connects hydraulic pump,
The inner surface of the upper end connection upper cover 2 of filter core 5, is additionally provided with gasket 6, upper cover 2 and hydraulic oil container 1 between upper cover 2 and filter core 5
Be additionally provided with lower seal pad 3 between upper surface, be connected through a screw thread between filter core 5 and fuel sucking pipe 11, upper cover 2 and hydraulic oil container 1 it
Between be connected by screw to.
When hydraulic pump stops working, for the ease of oil return, the upper surface of hydraulic oil container 1 is additionally provided with several oil return holes 12,
Oil return hole 12 is set between lower seal pad 3 and fuel sucking pipe 11.
Specifically, oil return hole 12 has multiple, multiple oil return holes 12 are symmetrical centered on 11 axle center of fuel sucking pipe, upper cap bore
21 have 6, and 6 upper cap bore 21 are equally spaced along 2 circumference of upper cover.
In order to promote the sealing performance between filter core 5 and fuel sucking pipe 11, when the two being avoided to connect, using raw material band or sealing
Circle, the preferred pipe screw thread of the connection screw thread of the present embodiment between the two.
Specifically, the preferred glass filter paper filter core of the present embodiment filter core 5, chemical fibre filter paper or wood pulp filter paper.
