Abstract

The invention provides a double-acting reciprocating booster pump and belongs to the technical field of reciprocating pumps. The double-acting reciprocating booster pump is composed of a double-step plunger piston and a pump body. A left volume cavity and a right volume cavity are arranged on the pump body, a suction valve assembly I and a discharge valve assembly I are installed in the left volume cavity, and a suction valve assembly II and a discharge valve assembly II are installed in the right volume cavity. The double-step plunger piston and a sealing assembly of the double-step plunger piston are installed between the left volume cavity and the right volume cavity and separate the left volume cavity and the right volume cavity. The double-acting reciprocating booster pump is novel in structural design, has two flow discharging strokes in one reciprocating motion stroke of the double-step plunger piston and increases discharge flows in a multiplied mode. In addition, stress on two sides of the double-step plunger piston in the suction and discharge strokes are the same. The double-acting reciprocating booster pump always provides same acting force for a power end and solves the problem that the stress of a conventional booster pump in the suction and discharge strokes are uneven.

Description

The reciprocal suction booster of double-action
Technical field
The invention belongs to the reciprocating pump technical field, be specifically related to the reciprocal suction booster of a kind of double-action.
Background technique
Back and forth suction booster is a kind ofly to come the traditional mechanical to the liquid medium supercharging of being carried through drive plunger or reciprocating motion of the pistons, and the medium that it is carried is that certain inlet pressure is arranged.
Usually back and forth suction booster adopts the difference in areas of CONCENTRIC REDUCER plunger to come balance part inlet pressure to give the reaction force of power end.But owing to gap is always arranged when the inlet pressure that provides during design suction booster plunger CONCENTRIC REDUCER difference and head pressure data and real work, thereby always the proper functioning of power end is impacted.Chinese patent number is that 200910059897.4 patent of invention discloses a kind of inlet pressure balanced type boosting water injection pump.Its main feature is: (1) increases by one section the same microcephaly's plunger of front and back diameter again with the major part front end of routine techniques CONCENTRIC REDUCER plunger, becomes one big two little ladder plunger; (2) come balance ladder plunger to connect one side of power end through inlet pressure.The stressed variation with inlet pressure, head pressure of this structure plunger is irrelevant, has effectively changed the stressed of power end.But this structure equally also exists plunger power end when suction stroke and does not stress (theoretically), and power end is stressed when plunger is discharged stroke, the problem of discontinuity.Most importantly this structure is because the pump discharge flow rate is relevant with the difference in areas of ladder plunger, and when the needed discharge flow rate of pump is bigger, this structure just is difficult to realization.Because: microcephaly's plunger diameter of (1) ladder plunger can not be too little, and diameter is the insufficient strength of small plunger too, and also very big (elongate rod) machining accuracy of difficulty of processing is difficult to guarantee; (2) diameter at butt end of ladder plunger can not be too big; If increase diameter at butt end merely, concerning multicylinder pump, the cylinder spacing of pump is just very big so; The cylinder spacing of supporting with it power end is also very big; In general the power end bearing capacity that the cylinder spacing is big is also big, and it is rich the power end ability to occur, causes the waste of low load with strong power.Since ladder plunger major part can not be too large and small head can not be too little, also just limited the using scope of this patented technology.
Summary of the invention
The present invention is intended to solve the deficiency of existing technology, provides a kind of double-action reciprocal suction booster, utilizes a cover two ladder plunger, the pump housings (two cavity volumes about having on the pump housing) and is installed in two cover suction metering valve assemblies in the cavity volume of the left and right sides.In two ladder plunger once reciprocating movement processes, accomplish twice flow and discharge, increase discharge flow rate at double, and two ladder plunger bears identical plunger force at to-and-fro motion process medium power end always, makes power end stressed evenly, pulsating movement free.
Technical problem to be solved by this invention can realize through following technological scheme:
The reciprocal suction booster of double-action of the present invention; Be to constitute by the two ladder plungers and the pump housing; On the pump housing, be provided with left cavity volume and right cavity volume, install in the left cavity volume and be provided with suction valve assembly I and discharge valve assembly I, install in the right cavity volume and be provided with suction valve assembly II and discharge valve assembly II; Two ladder plungers and black box thereof have been installed between left cavity volume and right cavity volume, and two ladder plungers and black box thereof separate left cavity volume and right cavity volume.
As further improvement of the present invention, one section diameter identical subpost plug I and subpost plug II and black box thereof are arranged respectively at the two ends of two ladder plunger main plungers.
As further improvement of the present invention, the diameter of subpost plug I and subpost plug II is all less than the diameter of two ladder plungers.
The reciprocal suction booster of double-action of the present invention, when two ladder plungers moved right, the suction valve of left end cavity volume was opened; Expulsion valve cuts out; The left end cavity volume is accomplished suction process, and this moment, suction valve closure, the expulsion valve of right-hand member cavity volume were opened, and the right-hand member cavity volume is accomplished discharge process; When two ladder plungers during to left movement, the expulsion valve of left end cavity volume is opened, suction valve closure, the left end cavity volume is accomplished discharge process, this moment the expulsion valve of right-hand member cavity volume close, suction valve opens, the right-hand member cavity volume is accomplished suction process.
The reciprocal suction booster of double-action of the present invention, structural design is novel, in to-and-fro motion stroke of two ladder plungers, has twice flow to discharge stroke, increase at double the discharge flow rate of pump.Sucking and discharging in the stroke simultaneously, the stressed of two ladder plungers both sides is identical.All the time give identical active force of power end.Solved the problem of conventional suction booster discontinuity when discharge, suction stroke.
Description of drawings
Fig. 1, Fig. 2 are the different embodiments' of the reciprocal suction booster of double-action of the present invention structural representation;
Wherein: P1 is a suction pressure, and P2 is a head pressure; F1, F2 are the suffered power of urging of plunger; D is the main plunger diameter of two ladder plungers; D is two subpost plug diameters of two ladder plungers.
Embodiment
Embodiment 1
The reciprocal suction booster of double-action of the present invention; Be to constitute with the pump housing 2 by two ladder plungers 1; The pump housing is whole, and is as shown in Figure 1, on the pump housing 2, is provided with left cavity volume 9 and right cavity volume 10; Install in the left side cavity volume 9 and be provided with suction valve assembly I 4 and discharge valve assembly I 3, install in the right cavity volume 10 and be provided with suction valve assembly II 6 and discharge valve assembly II 5; At left cavity volume 9 and 10 of right cavity volumes two ladder plungers 1 and black box thereof have been installed, two ladder plungers 1 and black box thereof separate left cavity volume 9 with right cavity volume 10.And the one section identical subpost plug of diameter I 7 and subpost plug II 8 and black box thereof are respectively arranged at the two ends at two ladder plunger 1 main plungers, and the diameter of described subpost plug I 7 and subpost plug II 8 is all less than the diameter of two ladder plungers 1.
