Description

The many fluid cylinder combination slush pumps of a kind of plunger type
Technical field
This utility model belongs to the technical field of petroleum machinery, specifically, relates to the many fluid cylinder combination slush pumps of a kind of plunger type.
Background technology
The power section of traditional slush pump adopts toggle, and it is big that toggle takes up an area space.When the reciprocating motion that convert rotational motion is piston of toggle prime mover, the speed of piston is not a constant, and is similar to sine curve, thus, reciprocating pump instantaneous displacement in the course of the work is continually changing, and flow oscillation is big;Additionally, single hydraulic mechanism also results in the problem that flow oscillation is big, and the single hydraulic cylinder of slush pump coupling is large tank, and volume is big, cost is high, technical difficulty is big.
Utility model content
For deficiency above-mentioned in prior art, this utility model provides a kind of plunger type many fluid cylinder combination slush pumps, and this device can eliminate flow oscillation, and reduces machine volume under the premise ensureing output.
In order to achieve the above object, the solution that this utility model adopts is: the many fluid cylinder combination slush pumps of a kind of plunger type, including pulp-inlet pipe road, pulp pipeline and two groups of pump housings, the stock inlet, slurry intake chamber, slurry output chamber and the grout outlet that are sequentially communicated it is provided with in the pump housing, stock inlet connects with pulp-inlet pipe road, grout outlet and pulp pipeline communication, be provided with into slurry check valve, be provided with out slurry check valve between slurry intake chamber and slurry output chamber between stock inlet and slurry intake chamber.Two pump housings are connected to some groups of hydraulic packages, hydraulic package includes actively plunger case, actively plunger rod, actively cock body, driven plunger case, driven plunger rod, driven cock body and shaft coupling, actively one end of plunger case is provided with process oil pipe, actively the other end of plunger case is provided with backhaul oil pipe, actively cock body is arranged in active plunger case, and actively plunger rod is fixing with actively cock body is connected.Driven plunger case connects with slurry intake chamber, and driven cock body is arranged in driven plunger case, and driven plunger rod is fixing with driven cock body to be connected, and actively plunger rod is connected by shaft coupling is fixing with driven plunger rod.The some groups of hydraulic packages connected on one pump housing are completely in backhaul initial position, and the some groups of hydraulic packages that another pump housing connects are completely in process initial position.
Further, two pump housings are connected to 3-6 group hydraulic package.
Further, two pump housings are symmetrical and fixing connection.
Further, the grout outlet connection of two pump housings.
The beneficial effects of the utility model are, this device adopts two pump housings to work simultaneously, but the process of the hydraulic package of two pump housing connections and backhaul are alternating movement, eliminate flow oscillation;Hydraulic drive is adopted to replace toggle so that machine volume is little, lightweight, compact conformation, inertia are little, reaction is fast;Each pump housing connects alloplast and amasss the independent bulky hydraulic package that little hydraulic package replacement is original, reduces machine volume, and reduces the pressure that hydraulic package needs, reduces technical difficulty, and ensure that output.
