Abstract
The utility model relates to the technical field of electric pumps, in particular to an electric pump oil suction filtering structure not prone to blocking. The electric pump oil suction filtering structure not prone to blocking comprises a cylindrical oil suction hole located in an electric pump base and used for being connected with an oil suction pipe. The portion, close to the bottom, of the side wall of the cylindrical oil suction hole is provided with a filter screen installation hole communicated with the inner portion of an electric pump. A cylindrical filter screen matched with the filter screen installation hole and extending into the oil suction hole is arranged in the filter screen installation hole. Meshes of the filter screen are evenly distributed on the side wall of the filter screen and the bottom face of the filter screen. The cylindrical filter screen is adopted for the electric pump in the electric pump oil suction filtering structure, a traditional filter screen with one filtering face is converted into the integrated filter screen with the circumferential surface and the bottom face, the oil filtering area of the oil suction filter screen is greatly increased, and the phenomenon that use faults of the electric pump occur due to blocking caused by the small area of the filter screen is avoided.
Description
Technical field
The utility model relates to motor-drive pump technical field, is specifically related to the not susceptible to plugging motor-drive pump oil suction of one filtration.
Background technique
In current commercial vehicle operator cabin hydraulic overturn elevating system, the oil suction filter screen of motor-drive pump adopts hand rolled type filter screen mostly, or on fuel sucking pipe joint, adds a little filter screen, to realize the filtering function of hydraulic oil.Adopt this filter structure because of filter screen oil strain Area comparison little, the time, once for a long time causing impurity screening to stop up the phenomenon of filter screen, causes the operational failure of motor-drive pump.
Model utility content
The technical problems to be solved in the utility model is to provide the not susceptible to plugging motor-drive pump oil suction of one filtration, and it has increased the oil strain area of oil suction filter screen, has avoided because area of filter net is compared with the little motor-drive pump operational failure causing of stopping up.
The technical solution of the utility model is: the not susceptible to plugging motor-drive pump oil suction of one filtration, comprise and being horizontally set in electric pump foundation for connecting the cylindrical oil-sucking hole of fuel sucking pipe, on the sidewall of described cylindrical oil-sucking hole near bottom, have a filter screen mounting hole being connected with motor-drive pump inside, a drum-shaped filter screen that matches with it and extend in oil-sucking hole is installed in described filter screen mounting hole, and the mesh of described filter screen is evenly distributed on its sidewall and bottom surface.
Further, described oil-sucking hole is mutually vertical with filter screen mounting hole.
Further, the bottom of described filter screen and the inwall of oil-sucking hole do not contact.
The beneficial effects of the utility model are: the filter screen of this motor-drive pump oil suction filtration is drum-shaped, its mesh is evenly distributed on sidewall and bottom, make oil strain face become present whole circumferential surface and bottom surface by an original face, increase greatly oil strain area, avoided due to the too small blocking phenomenon causing of oil strain area.Cylindrical oil-sucking hole is vertical with filter screen mounting hole, and its degree of depth exceedes the position of filter screen mounting hole, not only increase the oil reserve of oil-sucking hole, also make the filter residue in oil under the impact of hydraulic oil, concentrate on the side that filter screen is relative with oil-sucking hole bottom, it is unimpeded that the other parts of filter screen still keep, further avoid the obstruction of filter screen, therefore can therefore not produce motor-drive pump operational failure.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of filter screen in the utility model;
Wherein: 1-filter screen, 2-filter screen mounting hole, 3-electric pump foundation, 4-motor-drive pump inside, 5-filter residue is concentrated place, 6-oil-sucking hole, 11-sidewall, 12-bottom surface, 13-mesh.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, be horizontally disposed with a columniform oil-sucking hole 6 in the electric pump foundation 3 of motor-drive pump, this oil-sucking hole 6 is for connecting fuel sucking pipe.On described electric pump foundation 3, be also provided with a filter screen mounting hole 2, this filter screen mounting hole 2 is opened at oil-sucking hole 6 on the sidewall near bottom, the sidewall that has filter screen mounting hole 2 is that described filter screen mounting hole 2 is connected with motor-drive pump inside 4 near a side of motor-drive pump inside 4.The degree of depth of described oil-sucking hole 6 exceedes filter screen mounting hole 2 positions, and a drum-shaped filter screen 1 matching with mounting hole is installed in filter screen mounting hole 2.As shown in Figure 2, on the circumferential side wall 11 of filter screen 1 and bottom surface 12, be evenly distributed with multiple mesh 13.Filter screen 1 extend into oil-sucking hole 6 inside, and all has certain distance with bottom and the inwall of oil-sucking hole 6.
When motor-drive pump work, by fuel sucking pipe, oil is drawn onto in oil-sucking hole 6, through the filtration of the drum-shaped filter screen 1 in oil-sucking hole 6, pure oil free from foreign meter flows into motor-drive pump inside 4 by filter screen mounting hole 2.
The filter screen 1 of this motor-drive pump is drum-shaped, its mesh 13 is evenly distributed on sidewall 11 and bottom surface 12, make the oil strain face of filter screen 1 become present whole circumferential surface and bottom surface by an original face, increase greatly oil strain area, avoided due to the too small blocking phenomenon causing of oil strain area.
Cylindrical oil-sucking hole 6 is vertical with filter screen mounting hole 2, and its degree of depth exceedes the position of filter screen mounting hole 2, not only increase the oil reserve of oil-sucking hole 6, also make the filter residue in oil under the impact of hydraulic oil, concentrate on the side that filter screen 1 is relative with oil-sucking hole 6 bottoms, it is unimpeded that the other parts of filter screen 1 still keep, and further avoided the obstruction of filter screen.
The above; be only embodiment of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
