Abstract
The invention relates to a hydraulic oil tank. The hydraulic oil tank comprises an oil tank body. A cover plate is arranged on the oil tank body. An oil suction tube and an oil return tube are arranged on the cover plate. A filter screen is arranged on the inner wall of the cover plate. The opening, in the oil tank body, of the oil return tube is arranged in the filter screen. A precipitation tank is arranged at the bottom of the oil tank body, the upper end face of the precipitation tank is lower than the bottom face of the oil tank body, and a closing plug is arranged on the lower end face of the precipitation tank. A first partition plate and a second partition plate are arranged in the oil tank body and fixed to the inner wall of the oil tank body. A sealed cavity is formed in one side of the oil tank body, and an air bag is arranged in the sealed cavity and communicated with the interior of the oil tank body through an air tube. The hydraulic oil tank has the advantages of not making contact with outside air, being capable of adjusting the pressure in the oil tank by itself and good in filtration effect, effectively discharging impurities in hydraulic oil, preventing the impurities from flowing in the hydraulic oil and the like.
Description
Technical field
The present invention relates to fuel tank technical field, particularly a kind of hydraulic oil container.
Background technique
In effective hydraulic control system, the intrusion of pollutant and the generation of pollutant are the key points improving the hydraulic system life-span.But, existing hydraulic oil in use can cause particulate contamination in air to be mixed in fluid, these impurity can cause the wearing and tearing of hydraulic element relative motion surface, the mouth of pipe blocks, system works reliability is greatly reduced, though be provided with fuel outlet bottom traditional hydraulic oil container, fuel outlet does not have cavity volume, such impurity along with running of hydraulic power oil, can affect the normal work of whole hydraulic system.
Summary of the invention
For the problems referred to above, the object of this invention is to provide one and refuse contacting external air, can regulating oil tank internal pressure voluntarily, and good filtration effect, the impurity in effective exudate force feed, can prevent the hydraulic oil container that impurity flows in hydraulic oil.
Realize technological scheme of the present invention as follows:
A kind of hydraulic oil container, comprise fuel tank, described fuel tank is provided with cover plate, cover plate is provided with fuel sucking pipe and return tube, cover plate inwall is provided with filter screen, the return tube mouth of pipe being positioned at fuel tank is arranged at filter screen, tank bottoms is provided with subsing tank, the upper-end surface of subsing tank is lower than the bottom surface of fuel tank, the lower end surface of subsing tank is provided with closing cock, and be provided with in fuel tank and be fixed on the first dividing plate on inner wall of oil tank and second partition, fuel tank side is provided with seal chamber, be provided with air bag in seal chamber, air bag is communicated with fuel tank internal by tracheae.
Described first dividing plate and second partition are arranged at the both sides of subsing tank, first dividing plate and fuel sucking pipe are positioned at the same side, and second partition and return tube are positioned at the same side, and advantage is convenient to isolate impurity, prevent impurity from entering fuel sucking pipe, be also convenient in impurity buildups and subsing tank simultaneously.
Be threaded connection between described closing cock and subsing tank, advantage is convenient to dismounting.
Described fuel tank bottom surface is provided with four supporting foots, is welded in the corner of fuel tank respectively, and advantage can be used for supporting fuel tank, and be connected and fixed, support force is strong.
Described closing cock magnetic material is made, and advantage is convenient to hold impurity, is then convenient to cleaning.
The flexible rubber of described air bag is made, and advantage is that gas storage capability is strong, and good toughness, physical life is long.
Described tracheae is provided with envelope air valve, and advantage can be used for isolation air bag and fuel tank, also can be used for the air pressure in regulating oil tank, ensures stable gas pressure.
Have employed above-mentioned scheme, during fuel sucking pipe oil suction, first dividing plate can stop that precipitated impurities enters fuel sucking pipe, prevent the degree of purity of fuel sucking pipe blocking and fluid, second partition enters fuel sucking pipe after can be used for stopping foam, is convenient to Bubble, first dividing plate and second partition also make oil back region and oil suction separate out, increase the path of oil circulation, reduce the speed of circulation of fluid, there is cooling effect; Filter screen is for isolating the impurity foreign matter in return tube, the fluid in preventing pollution fuel tank; Can be used for accumulated impurities in subsing tank, thus be convenient to thorough cleaning, improve the turbidity test of hydraulic oil; Because air bag is connected with fuel tank internal, so when the level change of fuel tank inner fluid, air pressure also can change, gas in such air bag carries out supply, ambient atmos is avoided to be mixed into, affect the degree of purity of fluid, also can prevent oil deteriorate simultaneously, thus improve the reliability and stability of hydraulic work system.
