Description

A kind of circulating type hydraulic pressure Oiltank structure
Technical field
The present invention relates to hydraulic oil container field, specifically refer to a kind of circulating type hydraulic pressure Oiltank structure.
Background technique
The main function of fuel tank in hydraulic system is: 1, storage is for the required fluid of systemic circulation; 2, the heat producing when emanation system is worked; 3, discharge the gas being mixed in fluid; 4, for the installation of element in system provides position.Fuel tank should be removed the dirt precipitating in fluid in time, and the fluid in fuel tank must make to meet the fluid that hydraulic system turbidity test require.As the important component part of hydraulic system, hydraulic oil container can be cooling timely by it in the system of working solution heat radiation, reduces the oxidation rate of fluid, reduces the corrosive wear of hydraulic element simultaneously.
Under severe highly polluted environment, extraneous air, water, dust and solid particulate matter are easy to enter into fuel tank, pollute the working life, the reliability that weakens hydraulic system that reduce hydraulic element and fluid when fluid, cause hydraulic system fault, seriously time, can cause the collapse of whole system.Traditional hydraulic oil container is in the time of work, wet air and dust inevitably can enter filter and enter into fuel tank, in the time changing filter, also unavoidably pollutant is taken in fuel tank in addition, and traditional hydraulic oil container central diaphragm is too near apart from return opening, cause oil circulation distance too short, fluid does not have time enough precipitated impurities, finally cause the entire amount of working solution to reduce, must supplement in time new working solution, when reducing fuel tank cycle efficiency, also cause the working strength of filter to increase, reduce working life.
Summary of the invention
The object of the present invention is to provide a kind of circulating type hydraulic pressure Oiltank structure, improve the cycle efficiency of working solution in fuel tank, reduce the consumption of working solution, improve the working life of component in fuel tank simultaneously.
Object of the present invention is achieved through the following technical solutions:
A kind of circulating type hydraulic pressure Oiltank structure, comprise casing, cooler, return filter and oil outlet are installed on described casing, cooler is connected with return filter by oil guide pipe, in described casing, be provided with Z-shaped dividing plate, casing is separated into both sides by Z-shaped dividing plate, a side that comprises oil outlet forms oil sucting cavity, opposite side forms oil back chamber, described oil sucting cavity is connected with oil back chamber by oil guiding hole, hydraulic oil cooler is installed in oil back chamber, and described hydraulic oil cooler is connected with described return filter; Also comprise air bag cavity, described air bag cavity is arranged in oil back chamber and is communicated with oil back chamber, in air bag cavity, be provided with air bag, air bag is communicated with outside by air-valve, on the inwall of air bag cavity, have groove, be provided with baffle plate in groove, baffle plate is connected with bottom portion of groove by spring, on described baffle plate, pressure transducer is installed, pressure transducer is connected with air-valve by wire.When the present invention works, the hydraulic oil of high temperature enters into oil back chamber by after cooler cooling for the first time by oil guide pipe, sludge in hydraulic oil the filtration of filter dirty enter in hydraulic oil cooler, because cooling middle hydraulic oil is for the first time also with certain remaining temperature, residual heat makes hydraulic oil can affect transmission efficiency in the time entering in transmission part, after the second cooling action of hydraulic oil cooler, the liquid level of hydraulic oil starts to rise in oil back chamber, now the Volume Changes of the hydraulic oil in fuel tank need to be by exchanging to realize with the gas of external environment, but extraneous pollutant can enter into fuel tank together along with ambient atmos, cause hydraulic oil to be polluted, the air bag arranging in oil back chamber can be got back to total discharge in oil back chamber while being greater than the output flow of oil hydraulic pump in hydraulic system, the volume of the hydraulic oil in oil back chamber increases, the compressed formation malleation of volume of air, when hydraulic oil supplements oil back chamber volume, air enters air bag, its inside air bag volume is increased, now hydraulic oil flows in oil sucting cavity by oil guiding hole, by discharging in oil outlet, in the time that the hydraulic fluid flow rate flowing out in oil outlet is greater than the flow of the oil return in oil back chamber, in oil back chamber, form negative pressure because of reducing of hydraulic oil volume, its volume reducing can make the volume of leather bag reduce, in oil guide pipe, hydraulic oil can accelerate to enter into oil back chamber and supplement the volume reducing, and then keeps the hydraulic oil stable circulation operation in oil back chamber and oil sucting cavity, fuel tank internal is divided into three chambers, adjust the variation of air bag volume according to the hydraulic oil Volume Changes in oil back chamber, avoid fuel tank to carry out gas exchange with external environment at work, and then reduced environmental contaminants and enter into the chance in fuel tank, increase the working life of component in fuel tank, the two-stage cooler arranging can improve the radiating efficiency of hydraulic oil, prevents that hydraulic fluid pressure from producing pulsatile change, and heat is taken away stably, reaches lowering temperature uniform effect stably, improves the cycle efficiency of hydraulic oil simultaneously, the loop control of hydraulic oil of the present invention is mainly changed and is realized by air bag inner volume, but in the time there is leakage of oil situation in fuel tank, pressure in air bag changes to lack timely and effectively to be monitored, constantly injecting air is easy to air bag cavity to cause damage, setting pressure sensor in the groove having on air bag cavity inner wall, in the time that air bag volume constantly becomes large, air bag is applied on air bag cavity inner wall, when the stressed arrival reference value of pressure transducer, control air-valve reduces or cuts out to the injection of air, avoid air bag excessively to inflate and break, because air bag Volume Changes is very fast, the spring of installing in groove and baffle plate can be applied to air bag the stress buffer on pressure transducer, strengthen the working life of pressure transducer.
On described casing, be provided with pouring orifice, described pouring orifice is connected with the upper end of oil back chamber.The deficient change that causes air bag volume when avoiding the substandard oil mass of hydraulic oil total amount in fuel tank occurs with the situation that makes up oil back chamber inner volume and change, on casing, offer pouring orifice, and pouring orifice is connected with the upper end of oil back chamber, can in oil back chamber, inject new hydraulic oil in time for staff, to keep the pressure stability in oil back chamber, ensure the fuel tank fuel feeding that circulates reposefully.
In described oil back chamber, be provided with level meter.Level meter can read the hydraulic oil liquid level height in oil back chamber in time, observes in time and judges the level condition in fuel tank for staff.
In described oil back chamber, magnetic screen is installed, described magnetic screen is between hydraulic oil cooler and described return filter.Working long hours in process of hydraulic system, between each component, can produce certain wearing and tearing, the tiny chip that wearing and tearing produce can be got back in oil back chamber with hydraulic oil, in using process repeatedly, can produce significantly impact to the working efficiency of hydraulic system, the magnetic screen of installing can be collected the metal fragment producing, reduce the impact on component in hydraulic system, improve hydraulicdriven effect.
