Example (b):
referring to fig. 1-2, the hydraulic oil tank with the air breathing capsule comprises an oil tank main body 3, wherein an airtight tank body 1 is arranged on the oil tank main body 3, the air breathing capsule 6 is arranged in the inner cavity of the airtight tank body 1, and the air breathing capsule 6 is communicated with the external atmosphere; inert gas is filled between the airtight box body 1 and the air breathing capsule 6, and the inner cavity of the airtight box body 1 is communicated with the oil tank main body 3 through the vent pipeline 2.
In this embodiment, as can be seen from fig. 3, the working process of the present invention is: when the hydraulic system operates, when the oil in the oil tank main body 3 is more than the return oil, the hydraulic oil in the tank body of the oil tank main body 3 is reduced, and the air pressure in the oil tank main body 3 is reduced; in order to maintain the gas pressure in the tank body 3, the inert gas in the airtight tank 1 flows into the tank body 3 through the vent line 2; at the moment, the air pressure in the airtight box body 1 is reduced, and air enters the air breathing capsule 6 from the external atmosphere; the air breathing capsule 6 is inflated to increase its volume so as to equalize the air pressures of the airtight container 1 and the fuel tank body 3.
When the oil in the oil tank main body 3 is less than the return oil, the hydraulic oil in the tank body of the oil tank main body 3 is reduced, and the air pressure in the oil tank main body 3 is increased; in order to maintain the gas pressure in the tank body 3, the inert gas in the tank body 3 flows into the airtight tank 1 through the vent line 2; at this time, the air pressure in the airtight box 1 is increased, and the air breathing capsule 6 is exhausted to the outside atmosphere under the action of the inert gas pressure; the air breathing capsule 6 is deflated and reduced in volume to balance the air pressures of the airtight box 1 and the oil tank body 3.
At present, there is also a hydraulic oil tank which isolates the atmosphere by air supply of the air bag, but compared with the utility model, if under the condition of the pressurization work, the air pressure is increased by the expansion of the air bag to absorb the gas transmitted from the oil tank main body 3, when the expansion of the air bag exceeds the set value, the air bag is easy to expand and burst; and in the utility model discloses in, atmospheric pressure is born by airtight type box 1, and air respiration gasbag 6 dwindles this moment, and airtight type box 1 can bear bigger atmospheric pressure, and the security is higher.
In the working process, the gas flowing between the airtight box body 1 and the oil tank main body 3 is inert gas filled after pretreatment, so that the hydraulic oil in the oil tank main body 3 is isolated from the external atmosphere, the water vapor and dust in the external atmosphere are prevented from entering, and the hydraulic oil is ensured to have good cleanliness. The pretreatment is mainly to dry the gas, so that water vapor is prevented from entering the gas, the inert gas is stable in chemical property and not easy to chemically react with the hydraulic oil, and the cleanliness of the hydraulic oil is improved.
In addition, the airtight type box body 1 can be designed integrally with the oil tank main body 3 in the design process, and the hydraulic oil tank adopting the mode has good integration degree and is more attractive integrally; also can adopt split type design, with airtight type box 1 individual design, adopt this kind of mode more nimble, can be used for reforming transform current hydraulic tank with airtight type box 1 and air breathing capsule 6 as the monomer unit, make current hydraulic tank also can reach isolated atmospheric technological effect.
Further, the air breathing capsule 6 is fixedly connected with the airtight box body 1 through a flange. The two flanges are respectively welded on the opening of the airtight box body 1 and bonded at the opening of the air breathing capsule 6, are butted and sealed at the joint of the airtight box body 1 and the air breathing capsule 6, and are used as a channel for air exchange between the air breathing capsule 6 and the outside atmosphere through a middle hole of the flange.
Further, an air filter 4 is butted at the opening of the air breathing capsule 6. Can effectively prevent dust suspended in the air from being sucked into the air arc-shaped capsule, thereby keeping the air breathing capsule 6 clean.
Further, a pressure release valve 7 communicated with the inner cavity of the airtight box body 1 is arranged on the airtight box body. When the air pressure in the airtight box body 1 exceeds the set pressure of the pressure release valve 7, the pressure release valve 7 is automatically opened to release the pressure, so that the pressure in the airtight box body 1 is ensured to be lower than the set pressure, and accidents are prevented.
Furthermore, the air breathing capsule 6 is made of nitrile rubber. The nitrile rubber is prepared from butadiene and acrylonitrile by an emulsion polymerization method, is mainly produced by a low-temperature emulsion polymerization method, and has the advantages of excellent oil resistance, higher wear resistance, better heat resistance and strong bonding force. The oil resistance of the nitrile rubber prevents the air breathing capsule 6 from being corroded by oil gas entering the airtight box 1 through the vent pipe 2.
Furthermore, an installation inspection hole is formed in one side of the airtight box body 1 and is sealed through the detachable cover plate 5, and therefore an operator can conveniently install and overhaul the air breathing capsule 6 through the installation inspection hole.
The embodiment of the present invention is the above. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly showing the verification process of the utility model, and are not used to limit the patent protection scope of the utility model, the patent protection scope of the utility model is still subject to the claims, all the equivalent structural changes made by using the contents of the specification and the drawings of the utility model are included in the protection scope of the utility model.
