Abstract
The utility model relates to a mud pump, which uses hydraulic pressure for driving. The hydraulic mud pump in the prior art adopts a mode that a hydraulic piston can be used for driving a mud piston for working, and can not sufficiently use return power; the horizontal double piston single function two-way hydraulic mud pump adopts that both sides of the hydraulic piston are provided with two piston rods, and each of piston rods is fixedly connected with a single-way mud piston for improving drive efficiency, and for simplifying the structure. When the hydraulic piston can be driven for straight-line motion through the hydraulic pressure, and the mud can be exhausted out or sucked in the horizontal double piston single function two-way hydraulic mud pump through pushing and pulling the two mud pistons; when the hydraulic piston is moved in reverse motion, and the reverse motion of the hydraulic piston is identical to the straight-line motion of the hydraulic piston. As a result, the hydraulic piston can always keep at full power operating status, and the high efficient conversion between the hydraulic energy and the mechanical energy can be realized.
Description
The utility model with utilize hydraulicdriven slurry pump relevant.
Existing slurry pump is a kind of mechanical device that rotating mechanical energy is converted to mud hydraulic coupling energy.It is made up of transmission system and power end and waterpower end.This slurry pump complex structure, because the effect of crank-connecting rod, the displacement amount of mud piston belongs to sinusoidal motion, causes the flow oscillation of mud liquid, and operating conditions is worsened, pump is fragile.
The hydraulic slurry pump of Chu Xianing has overcome above-mentioned part shortcoming in recent years, but it is lower to drive a mud piston efficiency with a hydraulic piston.When adopting the single-acting working method, power utilization is insufficient during backhaul; If adopt the double-action working method, because of the surface friction drag of mud rod seal place, transmission efficiency is also influenced.
The purpose of this utility model is to provide a kind of transmission device of complete symplex structure, realizes mechanical energy high efficiency transmission of--hydraulic pressure energy--mechanical energy and conversion, has solved the problem that makes full use of backhaul power, the two-way liquid of horizontal double-piston single-acting.The basic structure of pressure slurry pump and working principle are as shown in drawings.
Description of drawings and working principle:
It by the two large divisions totally 16 parts form, accompanying drawing has been drawn their rigging position.
(1) pump housing;
(2) left end single-acting mud piston;
(3) left end intermediate bar;
(4) left end liquid presses piston pole;
(5) hydraulic piston of band double buffering head;
(6) right-hand member liquid presses piston pole;
(7) right-hand member intermediate bar;
(8) right-hand member single-acting mud piston;
(9) plasmas channel;
(10) plasmas channel;
(11) indicating arm;
(12) compensation body;
(13) spring;
(14) little hydraulic piston;
(15) barrier film.
(16) hydraulicchange-over valve
When high pressure oil is entering chamber, a hydraulic jack left side under the control of hydraulicchange-over valve (16) after, hydraulic piston (5) moves right under the effect of high pressure oil, transmission promotion right-hand member single-acting mud piston (8) through right-hand member liquid presses piston pole (6) and right-hand member intermediate bar (7) moves right, the directed mud liquid of discharging under the control of one-way valve group; Meanwhile, hydraulic piston drags left end single-acting mud piston (2) through left end liquid presses piston pole (4) and left end intermediate bar (3) again and sucks mud liquid through the one-way valve group from mud pit.The high-pressure slurry liquid of output enters the right chamber of compensator (12) simultaneously, with the high pressure oil and the spring force balance in left chamber, storage compartment high-pressure slurry liquid, replenishes mud liquid to system when commutating in system, forms and exports operating mode stably.
Complete symplex structure of the present utility model is complete symmetrical assurance the by pump housing two ends; Wherein parts (2) and parts (8), parts (3) and parts (7), parts (4) are identical with the physical dimension of parts (6).
The utility model adopts horizontal installation, and mud piston and hydraulic piston are all done horizontal uniform motion in a straight line during work, its position.Move curve and be trapezoidal wave.
Double-piston in the utility model is meant two mud pistons; Single-acting is meant that the mud piston only upwards promotes mud extraction slurries side by side at folk prescription when doing horizontal uniform motion in a straight line; The two-way hydraulic piston that is meant is all exported full power mechanical energy on process and two moving direction of backhaul, two mud pistons one are pushed away one draw, and realizes discharging and sucking the function of mud liquid.
Slurry pump of the present utility model can cause the fluctuation of mud flow quantity when commutation, be equipped with mud liquid compensation device for this reason.Barrier film (15) separates mud liquid and hydraulic oil fully, because barrier film (15) quality is very little, compensator has the working band of broad.When hydraulic piston (5) commutated, the high pressure oil that comes from oil sources entered chamber, a compensator left side, promotes little hydraulic piston (14) and moves right, and forced the hydraulic oil presses against diaphragm of lumen to discharge mud liquid in the right chamber, replenished the mud liquid that is reduced because of commutation.When hydraulic piston (5) is finished the commutation operating mode, after entering the backhaul uniform motion, because indicating arm has reduced the useful area of little hydraulic piston (14) left end, the thrust that little hydraulic piston (14) is subjected to left produces motion, until the spring force balance thrust left.Above-mentioned motion makes little hydraulic piston (14) get back to original position, has carried out compensation next time and has prepared.
The test of the utility model slurry pump principle prototype and small-sized model machine confirms: the transmission efficiency of the utility model slurry pump can reach 85% to 90%, improves transmission efficiency 3% to 5% than mechanical type slurry pump; The mud flow quantity is in the trip segment more than 95% and waits flow output stably, the commutation operating mode section 5%, because the effect of compensator, its flowed fluctuation is also in 20%.
