Description
Technical field
The utility model belongs to the hydraulic system fuel feeding hand pump field in aircraft, helicopter, specifically a kind of small-sized
Band fuel tank plunger pump fueller.
Background technology
Domestic hand plunger pump is common Hydraulic Elements in airplane hydraulic pressure transmission system, traditional hand plunger pump at present
Other oil distrbuting box is needed, is connect with fuel tank by oil pipe, and the defects such as that there are fuel feeding efficiency is low, oil mass is low.
Invention content
The purpose of this utility model is to provide a kind of mini zone fuel tank plunger pump fuellers, and fuel tank and the pump housing are integrated
It is integrated, it is small, space has greatly been saved, oil filtering function, and install convenient has been carried, improves fuel feeding efficiency and fuel feeding
Amount.
Realize that the technical solution of the utility model aim is：A kind of mini zone fuel tank plunger pump fueller, it is special
Sign is：Including handle component, plunger rod component, the pump housing, pressure limiting valve a, oil outlet pressure inlet, pressure limiting valve b, fuel tank and oil inlet
Pressure inlet；It is equipped with three oil circuits in fuel tank, is connected respectively with oil inlet, oil outlet, plunger rod gymnasium, three oil circuits are homogeneous
It is logical；At the oil inlet of oil circuit, pressure limiting valve b is mounted on oil circuit by the pump housing built-in limited valve a and pressure limiting valve b, pressure limiting valve a
Oil outlet；Oil outlet pressure inlet and oil inlet pressure inlet are separately mounted at the oil outlet and oil inlet of the pump housing；Handle portion
Part is connected with plunger rod component, and handle component is connected through a screw thread on the handle set for being fixed on the pump housing, swinging handle component band
Dynamic plunger rod component movement.
The utility model compared with prior art, remarkable advantage：（1）The utility model integrated level is higher, parts compared with
Few, small, reliability is high.（2）Use space is saved, installation process is simplified, reduces cost, while improving fuel feeding effect
Rate, use scope is extensive, is easy to be widely applied.
Description of the drawings
Fig. 1 be according to this utility model proposes mini zone fuel tank plunger pump fueller exploded view.
Specific implementation mode
The embodiment of the utility model becomes one fuel tank and the pump housing, and plunger rod is pacified into and out of oily pressure limiting valve and oil circuit
It is placed in fuel tank internal, makes to form pressure difference with outside in the pump housing by the upper lift of plunger, by oil from oil inlet inspiration fuel tank, then lead to
The oil of fuel tank is discharged from oil outlet for the extruding for crossing plunger, forms a fuel feeding cycle in this way.
With reference to Fig. 1 be described in detail according to the utility model proposes specific device details and working condition.
The device mainly includes handle component 1, plunger rod component 2, the pump housing 3, pressure limiting valve a4, screw plug a5, screw plug b6, screw plugs
C7, oil outlet 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
The oil outlet of oil circuit.Oil outlet pressure inlet 8 and oil inlet pressure inlet 11 are separately mounted to the oil outlet and oil inlet of the pump housing 3
Place.There are three oil circuits in fuel tank, is connected respectively with oil inlet, oil outlet, plunger rod gymnasium, three oil circuits communicate, and
It is provided with outlet on 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 outlet pressure inlet 8, oil inlet pressure inlet 11 are connect 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 component 2, and handle component 1 is connected through a screw thread the handle set for being fixed on the pump housing
On, swinging handle component 1 drives plunger rod component 2 to move, and the head of plunger rod component 2 is equipped with two layers of rubber seal, plays
Sealing function prevents 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 springs in the pump housing 3
Compression, ball valve are opened, and hydraulic oil enters in fuel tank 10 and pump housing oil circuit, and plunger rod component 2 moves upwards at this time, fuel tank 10 and pump
Full of hydraulic oil until plunger rod component 2 moves downward in body oil circuit, pressure is more than outside in fuel tank 10 and pump housing oil circuit at this time
Pressure, the pressure limiting valve b9 spring-compresseds in the pump housing 3, ball valve are opened, and hydraulic oil reaches confession by being flowed out in oil outlet pressure inlet 8
Oily purpose.
