Abstract
The invention relates to a leather bag oil bank of hydraulic system. Wherein, the oil is stored in the soft leather bag whose shape is variable to be complete separated from the air; when the volume of oil is changed caused by discharging or charging the oil or the change of temperature, the leather bag will be protruded or be concave relatively to keep the inner pressure with same as outer air to keep the clean of oil and the normal operation of said hydraulic system. The invention can overcome the defects of present switch oil bank, reduce the accidence, prolong the service life and apply variable fixed or movable mechanical apparatus.
Description
One, technical field: the fuel tank that the present invention relates to all kinds of hydraulic systems.
Two, background technique:
Fuel tank is the essential parts of hydraulic system, and its effect also plays a part bubble in heat radiation, the oil and water separation, precipitation well cuts except that the container as oil storage.Often are furnished with cooling or auxiliaries such as heater, air filter and level meter on it.Pump, valve and motor etc. are installed on it are then formed hydraulic power unit.
Common fuel tank is divided into two classes:
1, open type oil tank, its liquid level communicates with atmosphere, and hydraulic oil is because of extracting out or return and the oil temperature changing in the case, and the fluid volume often changes, so the volume of air in the case inner fluid sky also can change, and outes when advancing when causing air.In order to prevent to bring into dust and the impurity in the ambient air, keep the cleaning of fluid, on the case lid of open type oil tank, air filter (pneumostome) often is housed.But because filter precision is relative, also steam and oxygen can not be filtered, thus hydraulic oil is contaminated and oxidation, rotten be still unavoidable.
2, sealed reservoir, it is airtight container, does not communicate with atmosphere, fluid surface filling with inert gas, inflation pressure is about 0.05MP, casing is had the requirement of intensity, rigidity and sealing.When the hydraulic oil volume changed in the case, the pressure of casing gas also can change, and this causes the back pressure of the internal drainage of the oil return of hydraulic system and pump valve is unsettled, is not suitable for the system that fluid is imported and exported on a big scale.
As everyone knows, fluid is contaminated and rotten in the hydraulic system, not only can reduce its working life, prior it be most important, the modal factor that causes hydraulic system fault.Therefore, keep the cleaning of hydraulic system oil liquid, prevent its contaminated and oxidation, rotten be the important means that keeps the hydraulic system proper functioning.The atmosphere of passing in and out is the approach that oxygen, steam and solid particle later stage enters fluid, and this is that open type oil tank can't overcome.Service behaviour and its operating life of prolongation in order to keep fluid often need add antioxidant, antifoam additive and rust preventing agent etc. in oil.
Three, summary of the invention:
Bladder type oil tank of the present invention provides a kind of novel light fuel tank, when fluid and atmosphere are isolated fully, and to keep fuel tank inner fluid pressure be atmospheric pressure, so can keep the cleaning and the proper functioning of hydraulic system, reduce rate of fault, and the operating life that can prolong hydraulic oil effectively.This invention has overcome the defective that present above-mentioned two class fuel tanks exist, and more present fuel tank has substantial characteristics and progress.
Four, description of drawings and embodiment:
Fig. 1 is a garden tubular bladder type oil tank.
Fig. 2 is a casing shape bladder type oil tank.
Garden tubular bladder type oil tank by oily joint 1, leather bag 3 and cover on the outside housing 5 form.Leather bag 3 is as the oil vessel of variable volume, and the gas-filling bag of its material and structure and common hydraulic accumulator is similar, but filled with oil liquid 2 rather than gas.Oil joint 1 and leather bag 3 are made of one and are affixed with nut and housing, and housing 5 is because of stressed little, and available light rigid plastics (or sheet iron) is made, and its effect is that the protection leather bag is difficult for by sharp injury.5 of leather bag 3 and housings are air 4, and it communicates with the atmosphere of outside by the air filter 7 that is contained on the cap 8, and keeping the air pressure perseverance in the housing is atmospheric pressure.One end of leather bag 3 is equipped with dismountable port lid 6, is convenient to regularly to remove by other approach bring impurity in the fluid into.When the fluid volume in the leather bag changed, soft leather bag is corresponding made recessed flat or alteration of form that drum is protruding, and the pressure in the leather bag is identical with barometric pressure all the time.This kind fuel tank relatively is suitable for the land all kinds of facility that travel because of compact structure, good from heavy and light, airtight performance, keeps the cleaning of fluid in than rugged environment.
Casing shape bladder type oil tank is seen shown in Figure 2, casing is made up of the case shell 5 and the case lid 8 of irony, and leather bag 3 is inserted in the casing and filled hydraulic oil 2, the upper end of leather bag 3 is affixed three pipelines, a pipeline 1 is the import and export of hydraulic oil, in addition two import and export that pipeline 9 is cooling (or heating) medium.The bottom of leather bag 3 is equipped with dismountable port lid 6, is convenient to regularly to remove by other approach bring impurity in the fluid into.Air filter 7 and pump, valve and motor 10 etc. are installed on the case lid 8, are constituted hydraulic power unit.The performance characteristics of this kind fuel tank is identical with garden tubular bladder type oil tank, and it is than on the machinery that is more suitable for fixing.
