Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides a kind of hydraulic test bench fluid cleaning device, not only can improve oily ability, can also guarantee that oil cleanliness meets the demands.
Hydraulic oil container is divided into to strong magnetic filtering area, sump oil district and absolute oil district, can carries out more fully filtration and the gassing of fluid, precipitate preferably, stoped pollutant to enter the absolute oil district, improve the system turbidity test.
To achieve these goals, a kind of hydraulic test bench fluid of the utility model cleaning device, comprise fuel tank, in described fuel tank, is provided with dividing plate, and described dividing plate is divided into sump oil district and absolute oil district by fuel tank, and described sump oil district and absolute oil district communicate on fuel tank top; One end, the sump oil of described fuel tank are provided with strong magnetic filter in district; Described strong magnetic filter and fuel tank joint are provided with the system oil return mouth, and some groups of crisscross magnetic bars are installed in strong magnetic filter, and the side wall upper part of strong magnetic filter is provided with oil outlet; The below in described fuel tank bottom, sump oil district is provided with the recycle pump inlet port, the below in described fuel tank bottom, absolute oil district is provided with the recycle pump oil outlet, described recycle pump inlet port is connected with an end of filter by bypass circuit pump group, and the other end of filter is connected with the recycle pump oil outlet.
Described bypass circuit pump group comprises motor and pump, and motor is connected with pump, and described recycle pump inlet port is connected with filter by pump.
The top in top of oil-tank, sump oil district is provided with vent I, and the top in described top of oil-tank, absolute oil district is provided with vent II.
Compared with prior art, the utility model, by strong magnetic filter is set in fuel tank, has effectively improved the oily ability of crossing; By fuel tank being divided into to strong magnetic filtering area, sump oil district and absolute oil district, can carry out more fully filtration and the gassing of fluid, precipitate preferably, stoped pollutant to enter the absolute oil district, improve oil cleanliness, guarantee that oil cleanliness can meet the demands.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, strong magnetic filter, 2, the sump oil district, 3, the absolute oil district, 4, fuel tank, 5, the recycle pump oil outlet, 6, filter, 7, dividing plate, 8, pump, 9, motor, 10, the recycle pump inlet port, 11, system oil return mouth, 12, magnetic bar, 13, oil outlet, 21, vent I, 31, vent II.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this hydraulic test bench fluid cleaning device, comprise fuel tank 4, in described fuel tank 4, is provided with dividing plate 7, and described dividing plate 7 is divided into sump oil district 2 and absolute oil district 3 by fuel tank 4, and described sump oil district 2 and absolute oil district 3 communicate on fuel tank 4 tops; Be provided with strong magnetic filter 1 in one end of described fuel tank 4, sump oil district 2; Described strong magnetic filter 1 is provided with system oil return mouth 11 with fuel tank 4 joints, and crisscross some groups of magnetic bars 12 are installed in strong magnetic filter 1, and the side wall upper part of strong magnetic filter 1 is provided with oil outlet 13; The below in described fuel tank 4 bottoms, sump oil district 2 is provided with recycle pump inlet port 10, the below in described fuel tank 4 bottoms, absolute oil district 3 is provided with recycle pump oil outlet 5, described recycle pump inlet port 10 is connected with an end of filter 6 by bypass circuit pump group, and the other end of filter 6 is connected with recycle pump oil outlet 5.
Bypass circuit pump group comprises motor 9 and pump 8, and motor 9 is connected with pump 8, and described recycle pump inlet port 10 is connected with filter 6 by pump 8.
During use, the oil return of pilot system enters in strong magnetic filter 1 from system oil return mouth 11, fluid passes through some groups of interior magnetic bars of strong magnetic filter 1, progressively rises from the bottom of strong magnetic filter 1, after arriving oil outlet 13, enter sump oil district 2, in this process, some the iron media in fluid are filtered out by strong magnetic filter 1, improved the oily ability of crossing, simultaneously can also be by the air release in fluid out; The fluid that enters sump oil district 2 flows to bypass circuit pump group from recycle pump inlet port 10, then, after filter 6 filters, by recycle pump oil outlet 5, enters in absolute oil district 3; Fluid in absolute oil district 3, along with the rising of liquid level, finally flow back to sump oil district 2 on the top of fuel tank 4 naturally; So realize circulating filtration.Whole process is by the cooperation of the circulating filtration in 3, strong magnetic filter 1 and sump oil district 2 and absolute oil district, can carry out more fully the filtration of fluid, precipitate preferably, stoped pollutant to enter the absolute oil district, improved oil cleanliness, guaranteed that oil cleanliness can meet the demands.
