Abstract
The utility model provides a totally-enclosed hydraulic system which comprises an oil tank. An oil filler is arranged on the oil tank and is sealed through an oil tank cap. An oil tank breathing mechanism is arranged on the oil tank in sealing mode. Compared with the prior art, the totally-enclosed hydraulic system has the advantages of being reasonable in design, simple in structure, convenient to use, and the like. Air, water and dust can not enter into an air bag. The service life of the oil is prolonged, and the failure rate of a hydraulic system is greatly reduced.
Description
Technical field
The utility model relates to a kind of hydraulic system, specifically a kind of hydraulic system simple in structure, totally enclosed.
Background technique
Hydraulic system generally all is by fuel tank, filter, pump, valve, oil pipe and telescopic oil cylinder consist of a system, because in work and rest process, the temperature of system can be sometimes high sometimes low, will produce like this breathing phenomenon of fuel tank, this exhales a suction just, will be air and airborne moisture, dust etc. suck in the fuel tank, these materials and the violent lubricant oil (liquid) that flows will mix, particularly engineering machinery is in the tunnel, there is waste gas in factories etc., dust, air temperature variations is large, work under the large environment of humidity of the air, these materials enter in the lubricant oil (liquid) by respiration, on the working life of lubricant oil (liquid) and the working life of equipment all producing great impact, airborne oxygen enters in the lubricant oil (liquid), can accelerate the oxidation deterioration of oil (liquid), corrosion of metal, moisture can destroy additive in the oil and the oil film of metal surface, cause additive to lose efficacy and the corrosion of hydraulic system inner metal surface, dust also can enter work system with lubricant oil (liquid), easily stifled filter core, granule by filter core can scratch oil pump again, valve and oil cylinder, make equipment holddown occur, the faults such as card valve, waste gas is just larger to the injury of oil (liquid).So the fault of hydraulic system more than 70% is owing to the pollution of lubricant oil (liquid).
Therefore how to keep away this situation, a lot of people are solving by every means.Adopts measure mainly contains at present: adopt higher-quality lubricant oil (liquid), emphasis is the working life that the oxidation resistance of raising lubricant oil (liquid) prolongs oil product, next is to use higher-quality additive, moreover be exactly to install various filtrations additional at oiling (liquid) mouth, in the equipment oil circuit, install high-precision filtration equipment additional exactly in addition, but these measures all can not fundamentally solve a series of consequences that respiration produces.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provide a kind of simple in structure, avoid entering foreign material, totally enclosed hydraulic system.
The technical solution of the utility model realizes in the following manner, this a kind of totally enclosed hydraulic system,
Its structure comprises fuel tank, offers oil filler on the described fuel tank, and this oil filler is by oil tank cover sealing, and also sealing arranges a fuel tank respiration mechanism on fuel tank.Adopting the said structure setting is in order to create the fuel tank environment of a sealing, and the respiration of fuel tank just can be finished by the fuel tank respiration mechanism, avoided air, moisture, dust etc. then to enter in the fuel tank, prolonged the working life of oil product, and then greatly reduce fault ratio of hydraulic pressure system.
As improvement, the built-in filter screen of described oil filler.This is the foreign material that exist in the oil in order to filter roughly oil product, to filter, and then improves the quality of lubricant oil (liquid).
As preferably, described fuel tank respiration mechanism comprises air bag, ventilating cover, described air bag comprises interconnective utricule, fixed tube section, the utricule of this air bag partly is arranged on fuel tank internal, fixed tube section then stretches out between fuel tank and this fixed tube section and the fuel tank and is tightly connected, and the end that fuel tank stretches out in described fixed tube section is provided with ventilating cover.Adopt this structure can so that the respiration of fuel tank control by air bag, the compressed air of from ventilating cover, discharging of air bag during expiration, the air that sucks when air-breathing, moisture, dust etc. then enter in the air bag, effectively protect the fuel tank internal oil product not contaminated.
As preferably, the cross section of described fixed tube section is square, a kind of in triangle or the circle.These three kinds of structures are easy to make to realize most, and comparatively convenient when making.
As improvement, between described fixed tube section and ventilating cover, be provided with pad, section is corresponding with fixed tube, be square a kind of in ring-type, triangle ring-type or the circular ring-type of this pad.Pad is to prevent that fixed tube section is subject to the damage of ventilating cover, prolongs the working life of fixed tube section to a certain extent.
The beneficial effect that the utility model compared with prior art produces is:
The characteristics such as that a kind of totally enclosed hydraulic system of the present utility model has is simple in structure, easy to use, be skillfully constructed, the utility model comes the air-breathing of control system and exhales by air bag, avoided air, moisture, dust etc. then to enter in the air bag, prolong the working life of oil product, but also can greatly reduce fault ratio of hydraulic pressure system.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Mark in the accompanying drawing represents respectively:
1, oil filler, 2, fuel tank cap, 3, filter screen, 4, fixed tube section, 5, pad, 6, ventilating cover, 7, utricule, 8, fuel tank.
Embodiment
Below in conjunction with accompanying drawing a kind of totally enclosed hydraulic system of the present utility model is described in detail below.
As shown in Figure 1, this a kind of totally enclosed hydraulic system, its structure comprises fuel tank 8, offers oil filler 1 on the described fuel tank 8, and this oil filler 1 is by fuel tank cap 2 sealings, and also sealing arranges a fuel tank respiration mechanism, described oil filler 1 built-in filter screen 3 on fuel tank 8.
Described fuel tank respiration mechanism comprises air bag, ventilating cover 6, described air bag comprises interconnective utricule 7, fixed tube section 4, utricule 7 parts of this air bag are arranged on fuel tank 8 inside, 4 in fixed tube section stretches out between fuel tank 8 and this fixed tube section 4 and the fuel tank 8 and is tightly connected, and the end that fuel tank 8 stretches out in described fixed tube section 4 is provided with ventilating cover 6.
The cross section of described fixed tube section 4 is rounded, and namely the mouth of pipe is O shape, is provided with pad 5 between described fixed tube section 4 and the ventilating cover 6, and is corresponding with fixed tube section 4, and described pad 5 is and the smooth steel disc of the caliber of fixed tube section 4 circular shape of a size.
After using this device, the oiling mode is with original the same, in the operation without any change.Add the fuel tank behind the upper gasbag, in the equipment working procedure, because the respiration that the suction of pump and the effect of expanding with heat and contract with cold cause is finished by air bag fully, air bag is compressed during expiration discharges air from pneumostome, and the air that sucks when air-breathing, moisture, dust etc. then enter in the air bag.Only need smooth head when safeguarding and roll the flexible pipe that a circle eyelet is arranged and insert in the air bag to inhale with negative pressure and get final product.
