Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 to Fig. 3 is the structural representation of opposed type high-pressure plunger reciprocating pump of the invention, wherein, Fig. 1 shows this hair
The structural representation of the bent axle of the opposed type high-pressure plunger reciprocating pump of bright embodiment, Fig. 2 shows the opposed of the embodiment of the present invention
The bent axle of formula high-pressure plunger reciprocating pump and the attachment structure schematic diagram of connecting rod, Fig. 3 show that the opposed type of the embodiment of the present invention is high
The motion principle schematic diagram of hydraulic plunger reciprocating pump, for the ease of statement, only gives part related to the present invention in figure.
From Fig. 1 and Fig. 2, the opposed type high-pressure plunger reciprocating pump includes base member, on base member
Motor, power end pieces, the drive disk assembly being connected between motor and power end pieces and it is correspondingly arranged at power end pieces
Two fluid power end pieces of sidepiece.
Power end pieces include crankcase, and the bent axle on crankcase, the bent axle includes two sections of axles being coaxially disposed
Footpath 11, the odd number N suites being successively set between two diameters of axle 11 turn structure；Structure is turned per suite includes stagger vertically first
The both sides that crank throw 12a, the second crank throw 12b, the first crank throw 12a and the second crank throw 12b are disposed on axis in 180 °, N suites
Turn the first crank throw 12a circumferentially sequentially settings of interval angle α, angle of structureStructure is turned in every suite
A connecting rod 13 is connected on first crank throw 12a, the second crank throw 12b, in the present embodiment, crankcase uses middle open type,
It is easily installed and dismantles, big end uses split type structure, inside is equipped with bearing shell, is easy to and dismounts and change.
Fluid power end pieces include pump head body, and correspondence turns the first of structure per suite on the pump head body of power end pieces side
A cavity is respectively equipped with crank throw 12a, plunger 14 is respectively equipped with each cavity, a plunger 14 is bent with corresponding first
The connecting rod 13 turned on 12a is connected；Correspondence turns the second crank throw 12b of structure per suite on the pump head body of power end pieces opposite side
Place is respectively equipped with a cavity, and plunger 14 is respectively equipped with each cavity, and a plunger 14 is with corresponding second crank throw 12b's
Connecting rod 13 is connected, and certainly, fluid power end pieces part also including combination valve, stuffing box structure, structure of voltage regulation etc. constitutes, and enters discharge opeing
Valve uses combined non-return valve, valve block to open sensitive, and good sealing effect, volumetric efficiency is high, and structure of voltage regulation can improve because plunger is past
The pump housing that multiple pump reciprocating impulse causes vibrates.
Drive disk assembly include be arranged on crankshaft end on crankshaft pulley, the electrical machine belt pulley on motor output shaft, with
And the belt set around crankshaft pulley, electrical machine belt pulley, certainly, drive disk assembly can also be sprocket drive structure, gear-box biography
Dynamic structure etc..
The structure and principle of opposed type high-pressure plunger reciprocating pump are explained as follows with reference to Fig. 1, Fig. 2 and Fig. 3：
By taking ten plunger opposed type high-pressure plunger reciprocating pumps as an example, totally ten crank throws 1,2,3,4,5,6,7,8,9,10, every two
Individual adjacent crank throw is one group, is divided into five groups of A, B, C, D, E, then N=5, angle α=144 °, five the first crank throws 1,3,5,
7th, 9 144 ° of settings are circumferentially sequentially spaced, corresponding five the second crank throws are also circumferentially sequentially spaced 144 ° of settings, are turned per suite
First crank throw, second crank throw of structure are in 180 ° of settings.In the process of running, the plunger force F sizes of structure both sides are turned per suite
Equal direction not only improves bearing conversely, therefore casing is cancelled out each other to the support reaction of bearing along the axis direction of plunger 14
Service life, and can reduce vibration reduce noise；The axis of two plunger 14 that correspondence turns structure per suite is misaligned vertical
It is straight in producing moment of flexure on the axis direction of plunger 14, because two plungers 14 are at a distance of the moment of flexure very little of closer generation, therefore bent axle
Stress is changed into being primarily subjected to torque load from bearing moment of flexure, torque load, can extend the service life of bent axle；In power end
Part is respectively provided on two sides with a fluid power end pieces, and two fluid power end pieces are driven by a motor, relative to singly putting formula plunger
The volume increase flow of whole machine can effectively be reduced for reciprocating pump, and the purpose of energy-conservation can be reached.
Conventional three suites that also have of opposed type high-pressure plunger reciprocating pump turn structure, and this kind of situation has 6 crank throws, N=3,
Angle α=120 °, three the first crank throws are circumferentially sequentially spaced 120 ° of settings, and corresponding three the second crank throws are also circumferentially sequentially
The setting of 120 ° of interval；Seven suites turn structure, and this kind of situation has 14 crank throws, N=7, angle α=154.28 °, three first songs
Turn and be circumferentially sequentially spaced 154.28 ° of settings, corresponding three the second crank throws are also circumferentially sequentially spaced 154.28 ° of settings；Nine
Suite turns structure, and this kind of situation has 18 crank throws, and N=9, angle α=160 °, three the first crank throws are circumferentially sequentially spaced
160 ° of settings, corresponding three the second crank throws are also circumferentially sequentially spaced 160 ° of settings.
In the present embodiment, crank throw structure setting has five groups of A, B, C, D, E, and two close suites turn structure adjoining, also
It is to say turn between structure A and B in two adjacent suites, no longer set the diameter of axle 11 between B and C, between C and D, between D and E, and
It is directly to be directly connected to by radius bar, can so saves the space on axial direction, further reduces the volume of plunger reciprocating pump
And the moment of flexure size suffered by bent axle.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
