Abstract
A kind of hydraulic circuit of variable pump Leakage Energy, including link variable pump（1）Leakage oil export and hydraulic oil container（5）Leakage Energy pipeline（2）, return filter is arranged in series on the Leakage Energy pipeline（3）, and return filter outlet be arranged on hydraulic oil container in.The import and export parallel connection bypass check valve of the return filter（4）.The utility model can prevent substantial amounts of pollutant from flowing into hydraulic oil container, so as to ensure the cleannes of hydraulic oil.Simultaneously, when the Leakage Energy of variable pump is when by return filter, Leakage Energy loine pressure rises caused by return filter is blocked, after the pressure of rising reaches the Opening pressure of bypass check valve, the Leakage Energy of variable pump is through fluid pressure line, bypass check valve, hydraulic oil container is finally arrived, so that oil pipe line pressure of stopping a leak is excessive and causes the infringement to hydraulic pump, the service life of hydraulic pump is extended.
Description
Technical field
The utility model is related to variable pump, particularly a kind of hydraulic circuit of variable pump Leakage Energy.
Background technology
At present, the Leakage Energy of variable pump is all to be returned directly to hydraulic oil container by fluid pressure line, and variable pump works long hours
The particles such as the copper of generation is cut, powder, easily produce pollution, so as to reduce the oil cleanliness of hydraulic system to hydraulic oil container.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of variable pump for above-mentioned the deficiencies in the prior art
The hydraulic circuit of Leakage Energy, its can the copper that produces of filtered variable pump cut, the particle such as powder, in order to avoid produce pollution to hydraulic oil container.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used is：A kind of variable pump Leakage Energy
Hydraulic circuit, includes connecting on the leakage oil export and the Leakage Energy pipeline of hydraulic oil container of link variable pump, the Leakage Energy pipeline
Return filter is set, and the outlet of return filter is arranged in hydraulic oil container.
The import and export parallel connection bypass check valve of the return filter.
The utility model increases return filter on the Leakage Energy pipeline of variable pump, and the outlet of return filter is arranged on
In hydraulic oil container, such variable pump work long hours generation a large amount of copper cut, powder with Leakage Energy through return filter mistake
After filter, then the hydraulic oil of cleaning flowed into hydraulic oil container.
Compared with prior art, the beneficial effects of the utility model are：Prevent substantial amounts of pollutant from flowing into hydraulic oil container, from
And ensure that the cleannes of hydraulic oil.In addition, and to connect the bypass check valve oil pipe line pressure that can stop a leak excessive and cause to liquid
The infringement of press pump, extends the service life of hydraulic pump.
Brief description of the drawings
Fig. 1 is the hydraulic circuit of variable pump Leakage Energy of the present utility model.
Embodiment
As shown in figure 1, a kind of hydraulic circuit of variable pump Leakage Energy of the utility model includes the Leakage Energy of link variable pump 1
Return filter 3 is set on outlet and the Leakage Energy pipeline 2 of hydraulic oil container 5, the Leakage Energy pipeline 2, and return filter 3 goes out
Mouth B is arranged in hydraulic oil container 5, import and export A, B parallel connection bypass check valve 4 of return filter 3.In this way, variable pump 1 is let out
Oil leak enters hydraulic oil container 5 by return filter 3, can prevent substantial amounts of pollutant from flowing into hydraulic oil container 5, so as to ensure that liquid
The cleannes of force feed.Cause in Leakage Energy pipeline 2 pressure to rise when return filter 3 is blocked, if up pressure reach side
After the Opening pressure of logical check valve 4, the Leakage Energy of variable pump 1 flows into hydraulic oil container 5 through Leakage Energy pipeline 2, bypass check valve 4,
The infringement to variable pump 1 is caused so as to which the pressure for oil pipe line 2 of stopping a leak is excessive, the service life of variable pump 1 is extended.
