Abstract
The utility model provides a servo oil tank, and belongs to the technical field of machinery. The problem that the conventional servo oil tank is low in working performance and short in working service life is solved. The servo oil tank comprises a tank body with an oil outlet, the tank body is a closed tank body, the inside of the tank body is fixedly connected with a leather bag, and the leather bag is positioned above oil in the tank body. The utility model has the advantages that the servo oil tank is simple in structure, the oil can be ensured to be clean, and the working service life of the oil is prolonged.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of fuel tank, particularly a kind of fuel tank that is applicable on the servo.
Background technique
Fuel tank is the essential parts of hydraulic system, and its effect is also played the effect of bubble in heat radiation, the oil and water separation, deposition well cuts except the container as oil storage.Existing fuel tank is generally open type, i.e. its liquid level and atmosphere, and hydraulic oil often changes the fluid volume because of extracting or return affiliation out in the case, so the overhead air volume of case inner fluid also can change, and outes when advancing when causing air.The former of oil damage erodes pipeline, valve etc. because of airborne water, carbon dioxide entering oil the inside formation carbonic acid, makes the increasing of valve amount of leakage, the interior greasy filth that produces of fuel tank.In order to prevent to bring into dust and the impurity in the ambient air, keep the cleaning of fluid, air filter often is housed on the case lid of open type fuel tank.Because filter precision is relative; Also can not steam and oxygen be filtered; Therefore the hydraulic oil contaminated and oxidation of meeting still, airborne water, carbon dioxide entering oil the inside form carbonic acid and erode pipeline, valve etc., make the increasing of valve amount of leakage; Produce greasy filth in the fuel tank, thereby reduced the service behaviour and the operating life of fluid.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, proposed a kind of simple in structure, can guarantee that fluid is clean, prolong the servo fuel tank of fluid operating life.
The purpose of the utility model can realize through following technical proposal: a kind of servo fuel tank; Comprise casing with oil outlet; It is characterized in that described casing is enclosed housing and in casing, is fixed with leather bag that described leather bag is positioned at casing inner fluid top.
This fuel tank is separated into two chambers through leather bag with fuel tank, and one of them chamber is equipped with fluid, and when the fluid in the casing reduced, the downward indent of leather bag remedy fluid and reduce the space that the back is produced, thereby the air pressure that guarantees casing can not change; In like manner, when the fluid in the casing increased, leather bag raised up, and the protruding space of leather bag remedies fluid increases the space that the back is produced, and guaranteed that the air pressure of casing can not change.So just can guarantee that the air pressure in the casing is constant, need not be along with the increase and decrease of fluid extra increase and decrease air.
In above-mentioned servo fuel tank, be fixed with punch holder and die holder in the described casing, the fixing screw of passing through in described leather bag two ends is between punch holder and die holder.
Compared with prior art, the utility model is designed to fuel tank closed, and through the leather bag of design in casing along with the increase and decrease of fluid convexity and indent, guarantee that the air total amount in the fuel tank is constant.Thereby need not introduce air from the external world, stop water vapour, airborne impurity can not enter into hydraulic system yet, can be because of the impurity card valve in the external world not corrosion pipeline, valve etc., and the life-span of valve increases.Do not produce simultaneously greasy filth, fluid can longer-term ground keep clean with keep the frequency reduction that performance can more be changed oil than conventional system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, casing; 2, leather bag; 3, punch holder; 4, die holder; 5, screw.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, this servo fuel tank comprises the casing 1 with oil outlet, and casing 1 is an enclosed housing 1, in casing 1, is fixed with leather bag 2 and leather bag 2 and is positioned at above casing 1 inner fluid.In casing 1, also be fixed with punch holder 3 and die holder 4, leather bag 2 two ends are fixing to be fixed between punch holder 3 and the die holder 4 through screw 5.
This fuel tank is separated into two chambers through leather bag 2 with fuel tank, and one of them chamber is equipped with fluid, and when the fluid in the casing 1 reduced, leather bag 2 downward indents remedy fluid and reduce the space that the back is produced, thereby the air pressure that guarantees casing 1 can not change; In like manner, when the fluid in the casing 1 increased, leather bag 2 raised up, and leather bag 2 protruding spaces remedy fluid increases the space that the back is produced, and guarantees that the air pressure of casing 1 can not change.So just can guarantee that the air pressure in the casing 1 is constant, thereby need not introduce air from the external world, stopped water vapour, airborne impurity can not enter into hydraulic system yet, can be because of the impurity card valve in the external world not corrosion pipeline, valve etc., and the life-span of valve increases.Do not produce simultaneously greasy filth, fluid can longer-term ground keep clean with keep the frequency reduction that performance can more be changed oil than conventional system.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Claims (2)
