Description
Technical field
The utility model relates to self-unloading vehicle hydraulic system, especially self-unloading vehicle hydraulic system Fuel Tanking Unit.
Background technique
In now commercially adopting, the dumping car accounting of top set hydraulic jack is approximately about 30%, and the structure of middle top set hydraulic oil container is general comparatively simple, can only play simple oil storage effect, can not filter the impurity in hydraulic oil container.Due to the particularity of middle top set hydraulic system, fuel tank oil outlet takes into account the effect of oil return.And the return opening of fuel tank also can from fuel tank oil suction to cylinder upper cavity oil when large railway carriage or compartment declines.
The general structure in market is weld a distributing damper at the oil outlet position of hydraulic oil container, as shown in Figure 1, during to stop that large railway carriage or compartment declines, hydraulic oil is to the direct impact of top of oil-tank, but but can not impurity well in filtered fluid force feed, cannot prevent the impurity in fuel tank from entering pump valve and oil cylinder, cause the stagnant of valve and suppress pump, the faults such as leakage of oil pulled by oil cylinder.
Application number: 201220323048.2 applyings date: 2012-07-05 the utility model discloses a kind of hydraulic oil tank device, comprises casing, case lid, is provided with rubber pad between casing and case lid; The upper edge hole surrounding of casing is provided with connecting base, and case lid is fixedly connected with casing by connecting base; Case lid is provided with filler opening; The bottom of casing is provided with oil outlet, and the top of casing is provided with return opening; The bottom of casing is provided with purge cock.The utility model adopts the structure of similar pressure kettle, namely casing is separated with case lid, and between case lid and the lid mouth of casing, adds rubber pad seal, then is fixed by bolt and forms, the problem of thorough removal of contamination can be solved, use also fairly simple.
Application number: 201120524376.4 applyings date: 2011-12-15, the utility model discloses a kind of hydraulic oil container, and include PE rotational moulding oil box, oil box top has filler opening, and filler opening position has mounted cover fuel tank cap; Have fuel outlet bottom oil box, fuel outlet position plug is equipped with purge cock; The sidewall of oil box is provided with return opening and oil outlet, and return opening position is installed with oil returning pipe joint, and oil outlet position is installed with flowline connection to subsea.The utility model structure is simple, and reasonable in design, lightweight, the erosion of the most of soda acid of ability, is insoluble to common solvent under normal temperature, and chemical stability is good, and moisture absorption is little, oil resistant.Processing technology is simple, disposable plasticizing forming, and inner wall of oil tank is smooth, non-leakage, and can not corrode as iron sheet inner wall of oil tank the after stain fuel oil that comes off, and blocks mechanical Hydraulic System Oil road.
In such scheme when hydraulic pressure oil level is lower than filter core, gear pump will by the air intake oil cylinder in fuel tank, and when oil cylinder declines, in-oil cylinder air produces foam through filter core and overflows from tank filler.
Structure shown in Fig. 2, for install filter core additional at oil pipe oil outlet position, effectively can ensure that the impurity in fuel tank can not enter pump valve and oil cylinder like this.This scheme is when hydraulic pressure oil level is lower than filter core, and gear pump will by the air intake oil cylinder in fuel tank, and when oil cylinder declines, in-oil cylinder air produces foam through filter core and overflows from tank filler.
Filter core, while fuel tank oil outlet position installs filter core additional, sinks, increases air filter by the scheme shown in Fig. 3.The selection flow of filter core is at least greater than 100L/min, while guaranteed flow and filter precision, strengthens the diameter of filter core, reduces the height of filter core.
Oil cylinder is when complete lifting puts in place to adopt this structure to ensure, liquid level, still more than filter core, is unlikely to the air intake oil cylinder in fuel tank, like this would not because of generation foam from oil filler oil spout when oil cylinder declines.Can ensure that the impurity in fuel tank can not enter pump valve and oil cylinder simultaneously, cause the damage of hydraulic system.
Summary of the invention
The utility model is in order to ensure that fuel tank normally works not bleed, and the impurity ensureing in fuel tank can not enter in hydraulic jack and pump and valve, reduces the suction of air simultaneously, effectively extends the working life of hydraulic system, specially proposes self-unloading vehicle hydraulic system Fuel Tanking Unit.
The technical solution of the utility model is for this reason, self-unloading vehicle hydraulic system Fuel Tanking Unit, comprise fuel tank, the top of fuel tank is provided with air-strainer, the bottom of fuel tank is provided with fuel reserve tank, and fuel reserve tank and fuel tank UNICOM, is characterized in that: shoe cream room case sidewall or bottom are provided with oil filter, oil filter is completely in fuel reserve tank, and oil filter is outer is provided with oil outlet by flange.
The improvement of such scheme is: sidewall or the bottom of fuel reserve tank are provided with oil discharge screw.
The improvement of such scheme is: oil filter cross setting in shoe cream room, and is provided with oil outlet by flange.
Beneficial effect:
In the utility model, oil filter is all placed in fuel reserve tank, as long as have oil in fuel reserve tank, bleed would not be there is, oil in fuel tank is crossed fuel reserve tank completely and is flowed out, oil filter is completely in fuel reserve tank, so the impurity of oil filters filter by oil completely, impurity can not enter in hydraulic jack and pump and valve, reduces the suction of air simultaneously.
The setting of oil discharge screw is the impurity in order to clear up in time in fuel reserve tank.
The oil filter of cross setting is in order to the placement of fuel tank entirety is not interfered, and ensure that oil filter can not wash away because of the pressure returning oil, make it always in fuel reserve tank, the fuel tank of this structure can effectively avoid air to enter hydraulic system, simultaneously because filter core sinks to tank bottoms completely, when large railway carriage or compartment declines, the phenomenon that can not produce fuel tank bleed occurs.
The utility model can effectively prevent the impurity in fuel tank from entering gear pump pump and oil cylinder, cause gear pump and valve clamping stagnation, the volumetric efficiency of pump reduces and hydraulic jack is pulled, can ensure that oil cylinder can not by air intake oil cylinder when normal lifting simultaneously, guarantee, when oil cylinder declines, to overflow from oil filler.
The utility model prevents air from entering hydraulic system by the distance reducing cartridge top and tank bottoms, thus prevent oil cylinder hydraulic oil in dropping process from overflowing from crossing hydraulic fluid port, while saving hydraulic oil for user, extend the working life of car load hydraulic system, for user creates more income.
