Description
Technical field
The invention belongs to the hydraulic system fuel feeding hand pump field in aircraft, helicopter, specifically a kind of mini zone oil
Box column plug oil pump feed device.
Background technology
Hand plunger pump domestic at present is the Hydraulic Elements commonly used in airplane hydraulic pressure transmission system, traditional hand plunger pump
Other oil distrbuting box is needed, is connected by oil pipe with fuel tank, and the defects such as fuel feeding efficiency is low, oil mass is low be present.
The content of the invention
It is an object of the invention to provide a kind of mini zone fuel tank plunger pump fueller, fuel tank and the pump housing are integrated into one
Body, small volume, space is greatly saved, carried oil filtering function, and install convenient, improved fuel feeding efficiency and fuel delivery.
The technical solution for realizing the object of the invention is：A kind of mini zone fuel tank plunger pump fueller, its feature exist
In：Taken over including handle component, plunger rod part, the pump housing, pressure limiting valve a, oil-out pressure inlet, pressure limiting valve b, fuel tank and oil inlet
Mouth；Three oil circuits are provided with fuel tank, are connected respectively with oil inlet, oil-out, plunger rod gymnasium, three oil circuits communicate；
At the oil inlet of oil circuit, pressure limiting valve b is arranged on going out for oil circuit by the pump housing built-in limited valve a and pressure limiting valve b, pressure limiting valve a
Oil port；Oil-out pressure inlet and oil inlet pressure inlet are separately mounted at the oil-out of the pump housing and at oil inlet；Handle component
It is connected with plunger rod part, handle component is connected through a screw thread on the handle set for being fixed on the pump housing, and swinging handle part drives
Plunger rod part moves.
The present invention compared with prior art, its remarkable advantage：（1）Integrated level of the present invention is higher, and parts are less, volume
Small, reliability is high.（2）Save and use space, simplify installation process, reduce cost, while improve fuel feeding efficiency, use
It is in extensive range, it is easy to be widely applied.
Brief description of the drawings
Fig. 1 is the exploded view according to this mini zone fuel tank plunger pump fueller proposed by the present invention.
Embodiment
The solution of the present invention becomes one fuel tank and the pump housing, and plunger rod is placed in into and out of oily pressure limiting valve and oil circuit
Fuel tank internal, make to form pressure differential with outside in the pump housing by the upper lift of plunger, by oil from oil inlet inspiration fuel tank, then pass through post
The extruding of plug discharges the oil of fuel tank from oil-out, so forms a fuel feeding circulation.
The details and working condition according to specific device proposed by the present invention are described in detail with reference to Fig. 1.
The device mainly includes handle component 1, plunger rod part 2, the pump housing 3, pressure limiting valve a4, screw plug a5, screw plug b6, screw plug
C7, oil-out pressure inlet 8, pressure limiting valve b9, fuel tank 10, oil inlet pressure inlet 11.
Pressure limiting valve a, b totally 2 are housed altogether, at the oil inlet of oil circuit, pressure limiting valve b is mounted in pressure limiting valve a in its middle pump body 3
At the oil-out of oil circuit.Oil-out pressure inlet 8 and oil inlet pressure inlet 11 are separately mounted at the oil-out of the pump housing 3 and oil inlet
Place.There are three oil circuits in fuel tank, be connected respectively with oil inlet, oil-out, plunger rod gymnasium, three oil circuits communicate, and
Outlet is provided with the pump housing 3, is crammed and is shut with screw plug a5, screw plug b6, screw plug c7 respectively.Screw plug a5, screw plug b6, screw plug c7,
The thread root that oil-out pressure inlet 8, oil inlet pressure inlet 11 are connected with the pump housing 3 is equipped with rubber seal, plays sealing function,
Prevent pressure release and oil leak.
Handle component 1 is connected with plunger rod part 2, and handle component 1 is connected through a screw thread the handle set for being fixed on the pump housing
On, swinging handle part 1 drives plunger rod part 2 to move, and the head of plunger rod part 2 is equipped with two layers of rubber seal, plays
Sealing function, prevent pressure release and oil leak.
The course of work：
When oil inlet 11 oil suction of pressure inlet, external pressure is more than pressure in the pump housing 3, the pressure limiting valve a4 spring-compresseds in the pump housing 3,
Ball valve is opened, and hydraulic oil enters in fuel tank 10 and pump housing oil circuit, and now plunger rod part 2 moves upwards, fuel tank 10 and pump housing oil
Full of hydraulic oil until plunger rod part 2 moves downward in road, now pressure is more than external pressure in fuel tank 10 and pump housing oil circuit,
Pressure limiting valve b9 spring-compresseds in the pump housing 3, ball valve are opened, and hydraulic oil reaches fuel feeding mesh by being flowed out in oil-out pressure inlet 8
's.
