Abstract
The utility model provides an oil-returning and oil-filtering device for a mine hoist hydraulic station. The oil-returning and oil-filtering device for the mine hoist hydraulic station comprises a filter. The filter comprises an oil inlet oil circuit and an oil-returning oil circuit, wherein the oil inlet oil circuit and the oil-returning oil circuit are connected in parallel. The filter is arranged on the oil-returning oil circuit. One one-way valve is arranged on the oil inlet oil circuit, wherein the flow direction of the one-way valve is upward. Another one-way valve is arranged at a position, located at the inlet end of the filter, of the oil-returning oil circuit, wherein the flow direction of the one-way valve is downward. Due to the fact that the one-way valves are arranged on the oil inlet oil circuit and the oil-returning oil circuit respectively, the flow direction of hydraulic oil is unchanged, and the situation of clamping stagnation of a hydraulic valve caused by damage to the filter due to the fact that two ends of the filter are pressed is avoided.
Description
Technical field
The utility model relates to a kind of mine hoist hydraulic station oil return oil filter.
Background technique
Hydraulic station is to provide the device of stablizing power for hydraulic system.May have impurity when the hydraulic oil in the hydraulic system is back to hydraulic station, thereby stop up each valve body of hydraulic station, hydraulic system, cause the hydrovalve clamping stagnation.Therefore, existing hydraulic station is provided with filter at the oil circuit of oil-feed, oil return.
Mine hoist generally adopts hydraulic station as power source, and during oil return, hydraulic oil has very big pressure, and the filter bi-directional compression causes filter to damage, and can't filter the impurity in the hydraulic oil, and valve body is stopped up by impurity, causes the hydrovalve clamping stagnation.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of oil purifier of can effectively avoiding and damages, guarantees hydrovalve work mine hoist hydraulic station oil return oil filter smoothly.
The utility model is achieved in that
A kind of mine hoist hydraulic station oil return oil filter, comprise filter, its special way is: it contains oil-feed oil circuit and oil return circuit in parallel, described filter bits is on oil return circuit, be provided with at described oil-feed oil circuit and flow to one-way valve upwards, be positioned at the filter inlet end at described oil return circuit and be provided with and flow to downward one-way valve.
The beneficial effects of the utility model are:
Owing on the oil-feed oil circuit with on the oil return circuit one-way valve is being set respectively, the flow direction of hydraulic oil is fixed, avoided damaging because filter two ends pressurized causes filter, so that the hydrovalve clamping stagnation.
Description of drawings
Fig. 1 is hydraulic schematic diagram of the present utility model.
Among the figure: oil-feed oil circuit 1, one-way valve 2, oil return circuit 3, one-way valve 4, filter 5.
Embodiment
As shown in the figure, this mine hoist hydraulic station oil return oil filter comprises oil-feed oil circuit in parallel 1 and oil return circuit 3, be provided with filter 5 at oil return circuit 3, be provided with at described oil-feed oil circuit 1 and flow to one-way valve 2 upwards, be positioned at filter 5 entrance points at described oil return circuit 3 and be provided with and flow to downward one-way valve 4.
During oil-feed, flowed to 4 restrictions of downward one-way valve, hydraulic oil enters hydraulic system by oil-feed oil circuit 1, during oil return, is flowed to one-way valve upwards 2 restrictions, and hydraulic oil flows into fuel tank by oil return circuit 3.
Claims (1)
1. mine hoist hydraulic station oil return oil filter, comprise filter, it is characterized in that: it contains oil-feed oil circuit and oil return circuit in parallel, described filter bits is on oil return circuit, be provided with at described oil-feed oil circuit and flow to one-way valve upwards, be positioned at the filter inlet end at described oil return circuit and be provided with and flow to downward one-way valve.
