Description
Technical field
The utility model relates to a kind of hydraulic oil tank cover board assembly.Be applicable to engineering machinery and other industrial vehicle.
Background technique
In engineering machinery vehicle, general hydraulic oil container is all furnished with breath device, Main Function ensures that the pressure of fuel tank internal is identical with external pressure, can not produce larger positive pressure or negative pressure, and filter out some granules and moisture wherein when air turnover fuel tank.But the breath device poor filtration effect of Current Domestic, structure is single, often occurs bleed phenomenon.
At present, in engineering machinery and industrial vehicle, the fuel sucking pipe in general hydraulic system, resuscitation apparatus and tank cover are what to separate, install like this and compare effort, increase cost, and it is many to take place.Although also provide total for tank cover integrated to fuel sucking pipe, resuscitation apparatus and tank cover forming apparatus in prior art, often due to cover plate structure, screen material, the reasons such as mounting point, can not solve the phenomenon that resuscitation apparatus emits oil seepage very well.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, provides the hydraulic oil tank cover board assembly that a kind of structure is simple, easy for installation, to improve anti-oil gas bleed seepage property.
The technological scheme that the utility model adopts is: a kind of hydraulic oil tank cover board assembly, there is tank cover, fuel sucking pipe, resuscitation apparatus and suction tude, described fuel sucking pipe and suction tude are passed tank cover and are connected and fixed with tank cover, described fuel sucking pipe lower end is threaded oil suction filter core, it is characterized in that: described suction tude threaded upper ends connects resuscitation apparatus, the sleeve pipe be communicated with suction tude is welded in suction tude lower end, this sleeve pipe is built with oil resistant filter screen, and sleeve pipe is interior, oil resistant filter screen lower end arranges the baffle plate of band through hole and fixes through circlip for hole.
Described oil resistant filter screen filtration precision is 180 μm.
Described resuscitation apparatus adopts mazy type resuscitation apparatus, between its inside and outside atmosphere, filter screen is housed.
Described filter screen filtration precision is 10 μm.
Described sleeve pipe is fixedly welded on fuel sucking pipe side.
On described baffle plate, through-hole aperture is φ 4.
The beneficial effects of the utility model are: (1) increases suction tude on tank cover, is connected with resuscitation apparatus, effectively reduce and install taking up room of resuscitation apparatus separately, increase work efficiency.In addition can ensure that tank pressure balances by increasing suction tude, making fuel feeding smooth and easy.(2) suction tude lower end mounting sleeve, filling filter precision in it is 180 μm of oil resistant filter screens, effectively can stop that oarse-grained fluid overflows.(3) its lower end has the through hole of φ 4, is conducive to the oil droplet quick backflow after strainer filtering to fuel tank.(4) in resuscitation apparatus, employing labyrinth structure and filter precision are the filter screen of 10 μm, effectively stop moisture and tiny oil gas particle, and are discharged in air by air.(5) Socket welding is connected on fuel sucking pipe side, and the hydraulic oil container outer wall be close to fuel sucking pipe Yu installed, effectively avoids in driving conditions, and the fluid of concussion sputters always in sleeve pipe.
Accompanying drawing explanation
Fig. 1 is the stereogram of cover plate assembly of the present utility model.
Fig. 2 is the structural representation of resuscitation apparatus.
Embodiment
As shown in Figure 1, the present embodiment comprises tank cover 2, fuel sucking pipe 1, suction tude 4, sleeve pipe 5 and resuscitation apparatus 3.Fuel sucking pipe 1 and suction tude 4 are all fixed together with cover plate through tank cover 2, and wherein fuel sucking pipe 1 is inverted U-shaped, and fuel sucking pipe lower end mouth (being positioned at the port of fuel tank) place is provided with oil suction filter core 9, is threaded connection.Resuscitation apparatus 3 is arranged on suction tude 4 upper end, is connected by screw threads for fastening.Sleeve pipe 5 is placed on suction tude 4 lower end and is welded and fixed, and is communicated with suction tude 4.Sleeve pipe is the oil resistant filter screen 6 of 180 μm built with filter precision, and the baffle plate 7 with φ 4 through hole is installed in oil resistant filter screen lower end, and is fixed on internal surface of sleeve pipe through circlip for hole 8.This routine middle sleeve 5 is welded on the side of fuel sucking pipe 1, and be close to fuel sucking pipe 1 and the hydraulic oil container outer wall installed, can effectively avoid in driving conditions, the fluid of concussion sputters always in sleeve pipe.
As shown in Figure 2, in the present embodiment, resuscitation apparatus 3 adopts mazy type resuscitation apparatus, and filter screen 301 is housed between itself and outside atmosphere, and filter precision is 10 μm, effectively stops moisture and tiny oil gas particle, and is discharged in air by air.
Tank cover 2 is uniformly distributed the through hole of 6 diameter phi 7, is bolted on hydraulic oil container by M6, ensure that tank cover is installed more stable.
The working principle of the present embodiment is as follows: when this tank cover assembly is fixed on after on hydraulic fluid tank, hydraulic system carries out oil suction, and oil return operates.
During oil return, when being malleation in fuel tank, oil gas is entered by the through hole of sleeve 5 bottom baffle 7, and through oil resistant strainer filtering 6, in oil gas, oarse-grained fluid particle is effectively stopped, gas can pass through.Through the labyrinth structure of resuscitation apparatus 3 and the higher filter screen 301 of filter precision, the oil in oil gas substantially can be made to filter out completely, the oil droplet after filtration is back to fuel tank by the drainback passage of breath device 3, suction tude 4, sleeve pipe 5.
When being negative pressure in fuel tank, extraneous air then enters in fuel tank by resuscitation apparatus 3, and filter screen 301 can the dust of blocks air and moisture enter.
