Detailed description of the invention

Referring to Fig. 1,3,4,5,6,9,10,11, it is compact that it discloses a kind of plunger type using this utility model pedestal Hydraulic power unit.As shown in the figure: it includes oil immersed type motor 3 and the plunger displacement pump being arranged in the fuel tank 8 with end cap 1.This fuel tank 8 Inside it is additionally provided with oil-distributing plate 5；This plunger displacement pump uses high-pressure radial piston pump, according to uninterrupted by 3 or the plunger of more than 3 Paying 4 compositions (in figure as a example by 3), plunger is paid 4 and is fixed on motor 3 together with an oil-distributing plate 5；The electricity of this oil immersed type motor 3 Arbor uses bias design, drives when motor rotates plunger to pay 4 reciprocating motions and realizes oil suction and oil extraction；This oil-distributing plate 5 has Pay the pressure oil import 51 of 4 quantity corresponding to plunger, this pressure oil import 51 converges to pressure by the inner passage 50 of oil-distributing plate Power oil export 52；This oil-distributing plate 5 is connected on pedestal 12 (in figure as a example by die casting aluminium construction pedestals), the pressure on this pedestal 12 The pressure oil outlet 52 of oil inlet 121 corresponding connection oil-distributing plate 5, this pedestal 12 also has the pressure that pressure oil is transported to control valve Power oil export 122, pressure oil import 121 and pressure oil outlet 122 are interconnected in pedestal 12 body, connection system oil return Oil return import 123, and system oil return is flowed back to the oil return outlet 124 in fuel tank 8, this oil return import 123 and oil return outlet 124 It is interconnected in pedestal 12 body.

Such as Fig. 1,5,6, this pedestal 12 is die casting aluminium structure, and the pedestal upward pressure oil inlet 121 of this die casting aluminium structure has The pressure casting inlay part of steel.Aluminum diecast base uses disposable die cast, for overcoming the restriction of die casting aluminium bearing capacity, specially Devise the pressure casting inlay part of steel, for the transmission of pressure oil so that it is maximum operating pressure can reach 700bar, simultaneously Use die casting structure can also alleviate the weight of part.

Such as Fig. 2,7,8, this pedestal 12 is aluminum stretching structure.Aluminum stretching pedestal is used in the pressure applied field less than 350bar Closing, after being drawn into aluminium section bar, saw blade is machined out aftershaping.

In the compact hydraulic power unit of plunger type, plunger displacement pump use high-pressure radial piston pump, according to uninterrupted by 3,5,6 Individual or 7 plungers pay 4 compositions, are screwed on the front shroud of oil immersed type motor 3 together with oil-distributing plate 5.Oil-distributing plate 5 uses screw Being fixed on pedestal 12, fuel tank 8 and end cap are fixed on pedestal 12 by screw respectively.

In the compact hydraulic power unit of plunger type, use the complete oil immersed type motor 3 without shell, motor operation course produces Heat cooled down by fluid, good cooling results, it is possible to achieve the overpower of motor uses.Motor is manufactured by specialized factory, becomes This low, easy realization is produced in enormous quantities.Motor can reduce operation noise in being arranged on fuel tank 8 simultaneously.

In the compact hydraulic power unit of plunger type, the front shroud of oil immersed type motor 3 machined connection screwed hole, it is permissible that plunger pays 4 It is directly installed on the front shroud of motor.Motor shaft uses bias design simultaneously, drives plunger to pay 4 reciprocating motions when motor rotates Realize oil suction and oil extraction.Simple in construction, convenient installation, need not shaft coupling, compact conformation between pump and motor, extend complete machine Service life.

In the compact hydraulic power unit of plunger type, have employed oil-distributing plate 5, each plunger pays the pressure oil of 4 discharges by oil-distributing plate 5 Pool together and export the pressure oil import to pedestal 12, be finally delivered to control valve group.Permissible according to different pressure ratings Selecting different metal material processing oil-distributing plates 5, oil-distributing plate 5 is screwed on pedestal 12, simple installation.

In the compact hydraulic power unit of plunger type, fuel tank 8 uses aluminum to stretch section bar, can need to intercept not according to different volumes Same length, realizes different volume of fuel tank flexibly.Owing to avoiding welding procedure traditional when fuel tank manufactures, can significantly carry High efficiency and the quality of guarantee fuel tank.The fuel tank of aluminum is conducive to the diffusion of oil liquid temperature to cool down, and surface uses anodic oxygen Change can improve antiseptic power and improve aesthetic.There is on this fuel tank 8 oily form 9 and liquidometer 10.

In this utility model, this oil return outlet 124 connects and has oil return pipe 6, in this oil return pipe 6, be mounted with that a conduct is only The steel ball 7 of back check valve, prevents the fluid within fuel tank 8 from flowing out to outside fuel tank 8 when dismantling control valve.

In this utility model, this pedestal 12 side has control valve installed surface 126, rosette installing hole 125 and drain oil 127, this drain oil 127 arranges purge cock 11.Block drain oil 127 with purge cock 11 at ordinary times, need to change at fluid Shi Zuowei oil extraction window.

In this utility model, in this rosette installing hole 125, rosette 13, the power line of the motor in fuel tank 8, liquid are installed The lead-out wire of bit switch and temperature switch all collects in rosette interior[exterior 13.This structure can facilitate terminal block.

In the compact hydraulic power unit of plunger type, this oil-distributing plate 5 is steel design oil-distributing plate or cast-iron structure oil-distributing plate.From manufacture Cost consideration, cast-iron structure is mainly used in the occasion of below 320bar, such as Fig. 9,10,11.Application for other higher pressure Then using steel oil-distributing plate, such as Figure 12-15, they are to correspond respectively to the steel/aluminum oil-distributing plate that 4-7 plunger is paid.

In the compact hydraulic power unit of plunger type, this plunger pay 4 and oil-distributing plate 5 be directly installed on the front shroud of oil immersed type motor 3, On this end cap 1, there is air filter 2.

Referring to Figure 16 again, it is a kind of gear pump hydraulic power unit using this utility model pressure-casting type aluminium base.Such as figure Shown in: it includes oil immersed type motor 3 and the hydraulic pump being arranged in the fuel tank 8 with end cap 1.The company of being additionally provided with in this fuel tank 8 Connect support 5；This hydraulic pump uses the most fuel-displaced gear pump 4, and gear pump 4 is connected with the motor shaft of oil immersed type motor 3；This tooth The pressure oil outlet of wheel pump 4 is sent to pedestal 12 through the front cover shell of oil immersed type motor 3 with connecting in support 5 oilhole being connected Pressure oil import 121, it is to avoid flexible pipe road connects.The pressure oil that pressure oil is transported to control valve is also had to go out on this pedestal 12 Mouth 122, the oil return import 123 of connection system oil return, and system oil return is flowed back to the oil return outlet 124 in fuel tank 8.

Similarly, the pedestal of this gear pump hydraulic power unit can also use aluminum stretching structure pedestal as required.

It is only preferred embodiment of the present utility model in sum, is not used for limiting enforcement model of the present utility model Enclose.The most all equivalence changes made according to the content of this utility model claim and modification, all should be of the present utility model Technology category.
