Abstract
The invention relates to a reciprocating pump for delivering slurry containing solid grains, especially the hydraulic end flow passage of reciprocating diaphragm type, which comprises suck-in and discharge-out valve group, diaphragm and cylinder cap. It is characterized in that the flow passage outlet of the cylinder cap is of crescent structure, so that while delivering slurry, the slurry deposited downward can be flushed by the flowing slurry in the crescent shape flow-passage in a range of 120 degree at the bottom of the flow-passage so as to resolve most of deposition problem. The crescent flow-passage is formed by two eccentric circles, which is good in technical performance and easy for processing.
Description
[technical field]
The present invention relates to the technical field of reciprocating pump that a kind of conveying contains the slurry of solid particle, the particularly a kind of diaphragm type hydraulic end flow passage structure that can carry high pressure or low pressure slurry.
[background technique]
The reciprocating pump diaphragm type hydraulic end flow passage components are usually by liquid cylinder and cylinder cap, suck and composition such as expulsion valve group.In the flow passage structure of general diaphragm type hydraulic end, all exist cross or T shape to hand over the hole, slurry is flowed into by the suction valve group, arrives diaphragm end through the T shape runner hole of cylinder block and head bottom, is flowed out by the top outer pipe.This structure only is applicable to carries not solids-laden fluid and contains solid particle but sinking velocity slurry more slowly, carry when needs and to contain solid particle and sinking velocity faster during slurry, consider the sedimentation of solid particle, be easy to produce deposition in the cylinder base runner.And can only wash away the hole deposition of sub-fraction area on every side by the slurry that flows out in the runner hole, the solid particle of sedimentation will the cylinder base fluid scouring less than local constantly deposition, when deposition arrives to a certain degree, will hinder the reciprocating stroke of barrier film, influence the proper functioning of pump.
[summary of the invention]
The purpose of this invention is to provide a kind of reciprocating pump diaphragm type hydraulic end flow passage structure, it can more effectively reduce the deposition and the obstruction of slurry in the process of slurry body.
The present invention is achieved through the following technical solutions: a kind of reciprocating pump diaphragm type hydraulic end flow passage that can slurry body, its flow passage components comprise suction and expulsion valve group, cylinder cap, barrier film and cylinder body, no cross or T shape are handed over the hole in the runner, the suction runner exit of cylinder cap bottom is the crescent shape flow passage structure, its crescent shape runner by two 120 ° is formed, and one of them is 120 ° of bigger crescent shape runners, and another is 120 ° of less crescent shape runners.Slurry arrives diaphragm end through two 120 ° meniscate runners after flowing into cylinder cap bottom flow passage hole by the suction valve group, goes into the expulsion valve group by cylinder cap top runner orifice flow afterwards.
The invention has the beneficial effects as follows, when slurry body, in the scope of 120 ° of the slurries of deposit, can be subjected to washing away of slurry in the crescent shape runner in the runner bottom, thereby solve most deposition problems, and the crescent shape runner is made of the circle of two off-centre, good manufacturability, manufacturing easily.
[description of drawings]
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical sectional view of Fig. 1.
Referring to Fig. 1,1 is that cylinder cap 1,2 is that bigger 120 ° of crescent shape runners, 5 are that less 120 ° of crescent shape runners, 6 are cylinder cap bottom flow passage hole for cylinder cap 2,3 for barrier film, 4.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the present invention is described in detail:
As shown in Figure 1 and Figure 2, fluid end crescent shape runner of the present invention is mainly in the cylinder cap part.Cylinder cap is made up of two parts 1,2, is interconnected by screw, and 3 is barrier film, and 4 is 120 ° of bigger crescent shape runners, and 5 is 120 ° of less crescent shape runners, and 6 is cylinder cap bottom flow passage hole.
As shown in Figure 2, after flowing medium flows into cylinder cap by cylinder cap bottom flow passage hole 6, directly enter 120 ° of bigger crescent shape runners 4, because the sectional area of 120 ° of bigger crescent shape runners 4 is bigger, medium is full of whole 120 ° of bigger crescent shape runners 4 smoothly, whole then carrying out the transition in 120 ° of less crescent shape runners 5 flowed out in 120 ° of scopes by the crescent shape runner afterwards, thus most of deposition of solid of less 120 ° of crescent shape runners, 5 outlets before washing away.
Claims (2)
