Abstract
The utility model relates to a hydraulic pressure source device comprising an oil tank, a one-way valve, an oil filter, a safety valve and an oil return filter and further comprising an inclined disc type axial plunger pump and a radiator, wherein the radiator, the oil return filter, the oil tank, the inclined disc type axial plunger pump, the one-way valve and the oil filter are connected in sequence; the inclined disc type axial plunger pump is connected with the radiator; and the oil filter is connected with the radiator by the safety valve. Compared with the prior art, the hydraulic pressure source device has the advantages of stable working performance, long service life and the like.
Description
Technical field
The utility model relates to a kind of aircraft regular maintenance equipment, especially relates to a kind of hydraulic pressure source apparatus.
Background technique
YLY-2A type hydraulic pressure source apparatus, being mainly used to provides pressure and power supply for the hydraulic pressure detection ground installation of K8 aircraft inspection vehicle.These ground installations comprise hydraulic services multi-function test stand, pressurized strut test stand and equivalent coordination valve test stand.It can provide constant pressure and the alternating current 220V power supply of 25 ± 0.5MPa.
Original hydraulic pressure source apparatus uses ZB-34 oil pump heating value height, and noise is big.When detecting hydraulic services, under high pressure only 15 minutes, the oil temperature just up to 100 ℃ about.Have to quit work and work on again after wait oil temperature is cooled off.The process that has a strong impact on line service and make regular check on work is difficult to guarantee the rate of attendance of aircraft.If adopt the hydraulic pressure source apparatus of full import, not only cost an arm and a leg, and have the system matches problem.
Summary of the invention
The purpose of this utility model is exactly the hydraulic pressure source apparatus that a kind of stable work in work, long service life are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of hydraulic pressure source apparatus, this device comprises fuel tank, check valve, oily filter, safety valve, oil return filter, it is characterized in that, also comprise cam-type axial piston pump, radiator, described radiator, oil return filter, fuel tank, cam-type axial piston pump, check valve, oil filter connect successively, described cam-type axial piston pump is connected with radiator, and described oil filter is connected with radiator by safety valve.
Described cam-type axial piston pump is a variable displacement pump.
Described radiator is a fan-cooled radiator.
Compared with prior art, the utlity model has following advantage:
1, stable work in work, long service life;
2, noise is low;
3, temperature rise is low, but continuous operation.
Description of drawings
Fig. 1 is the structural representation of a kind of hydraulic pressure source apparatus of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of hydraulic pressure source apparatus, this device comprises fuel tank 1, check valve 3, oil filter 4, safety valve 6, oil return filter 8, also comprise cam-type axial piston pump 2, radiator 7, described radiator 7, oil return filter 8, fuel tank 1, cam-type axial piston pump 2, check valve 3, oil filter 4 connect successively, described cam-type axial piston pump 2 is connected with radiator 7, and described oil filter 4 is connected with radiator 7 by safety valve 6.Described cam-type axial piston pump 2 is a variable displacement pump.
Add radiator 7 on the hydraulic pressure source apparatus oil circuit.This cam-type axial piston pump 2 is variable displacement pumps, and noise is low, pressure height, stable work in work, long service life.Outlet pressure is adjusted at 25.5 ± 0.5Mpa, after cam-type axial piston pump 2 starts, cam-type axial piston pump 2 with full flow 15L/min to system's fuel feeding, simultaneously also to high pressure accumulator 5 fuel feeding, when system pressure reaches the Set pressure of cam-type axial piston pump 2, high pressure oil promotes the control valve on the cam-type axial piston pump 2, the stroking mechanism of control valve operation cam-type axial piston pump 2, the output flow of cam-type axial piston pump 2 is reduced, when the output flow of cam-type axial piston pump 2 and system equate with oil mass, the stroking mechanism of cam-type axial piston pump 2 maintains a certain position, when system need increase or reduce when using oil mass, cam-type axial piston pump 2 can change output flow automatically, keeps system oil pressure.When high-pressure tightness was tested, the actual flow of cam-type axial piston pump 2 approached 0, so power consumption is very little, and temperature rise is little.Can guarantee to work long hours.
Add radiator 7 on the oil circuit of hydraulic pressure source apparatus, described radiator 7 is a fan-cooled radiator, just starts working once energising.Deep fat enters radiator 7, and radiator 7 inside are the copper conduit, and the surface has radiating fin to increase heat diffusion area, and through forced air cooling, oily temperature is minimized.Fluid is through the circulation cooling like this, and hydraulic system can reach a thermal equilibrium.Can guarantee long time continuous working.Actual test time continuous operation 8 hours, temperature is no more than 80 ℃, satisfies usage requirement.
