Abstract
The invention discloses an inclined reducing type suction manifold, which comprises a water absorption tube and a plurality of water feeding tubes arranged on the water absorption tube at an interval, wherein the diameter of the water absorption tube is gradually reduced from front to back; the outlet end of the water feeding tube is provided with a hydraulic cylinder connection flange; the center axis of the water absorption tube and the plane of the hydraulic cylinder connection flange form an included angle which inclines to the bottom of the inlet end of the water absorption tube. According to the inclined reducing type suction manifold, a phenomenon that a reciprocating plunger pump is always subjected to insufficient suction can be solved by simple and reasonable structure design, accidents, such as sand plugging, air suction and water attack, caused by insufficient suction can be avoided, the service life of a plunger pump fluid end component is effectively prolonged, and residual hydraulic substances flow to a pipe mouth due to self weight since the inclined reducing type suction manifold is inclined, so a fluid end and the suction manifold are convenient to clean after operation.
Description
Technical field
The invention belongs to reciprocating plunger pump technical field, be specifically related to a kind of inclination diameter reducing type suction manifold.
Background technique
In the using process of the reciprocating pumps such as reinforcing oil well pump, fracturing pump, often running into because sucking liquid feed flow not enough, causing and inhaling sky, and water attack in plunger pump working procedure, cause quick damage or the inefficacy of component in pump; Especially in five cylinder pumps, traditional suction manifold is isodiametric horizontal suction manifold, liquid medium enters from one end, because the 5th cylinder is away from suction port, when medium goes to the 5th cylinder, because of flow minimizing, pressure drop, easily occur to inhale empty or water attack at the 5th cylinder, and because pressure is lower, the sand in medium easily deposits, occur husky stifled.Inhale sky, sand blocks up, water attack is all incidental accident in plunger pump using process.
Summary of the invention
For the defect that prior art exists, object of the present invention is exactly by designing new suction manifold structure, improving suction performance, reduces and avoids the sand caused because sucking deficiency to block up, inhale the accidents such as sky, water attack.
Technological scheme of the present invention is: comprise suction sleeve and multiple water inlets spaced apart on it; The diameter of described suction sleeve reduces from front to back successively, and the outlet end of described water inlet is provided with fluid cylinder adpting flange; The central axis of described suction sleeve and the plane of fluid cylinder adpting flange present the angle had a down dip to suction sleeve entry end.
Such scheme can be further designed to: the front portion pipe that described suction sleeve is reduced successively by caliber, front-middle transition tube, central tube, in-rear transition tube and rear portion Guan Gongwu section form; Each water inlet described is bend pipe structure that length is different and the fluid cylinder adpting flange that each water inlet outlet end connects is in same level.
The present invention is by the structural design of advantages of simple, the recurrent suction of reciprocating plunger pump can be solved not enough, the sand caused because sucking deficiency is avoided to block up, inhale the accidents such as sky, water attack, effectively improve the working life of hydraulic end of plunger pump parts, and because be tilting, residual liquid material flows to the mouth of pipe because of deadweight, clears up fluid end and suction manifold after being convenient to operation.

Embodiment
As shown in Figure 1, inclination diameter reducing type suction manifold 1 is primarily of suction pipe, water inlet 4 and fluid cylinder adpting flange 3 three part composition, and fluid cylinder adpting flange 3 is for being connected to the bottom of fluid cylinder 2; Water inlet 4 connects suction pipe and fluid cylinder adpting flange 3, and water inlet is made up of the bend pipe of 5 independent different lengths, connects suction pipe and fluid cylinder adpting flange 3 respectively; Suction pipe is made up of the pipe that multistage diameter is different, anterior pipe 5 respectively, front-middle transition tube 6, central tube 7, in-rear transition tube 8, rear portion pipe 9 form, pipe diameter reduces from front to back successively, realize reducing, because the diameter of far-end reduces, required flow reduces, and ensures pressure, and the feed flow of far-end can be avoided not enough; Suction pipe tube center and fluid cylinder adpting flange 3 form an angle, realize the suction manifold of inclination, when there is sand deposition in operation process, sand own wt can flow out along the pipe tilted, and decreases horizontal suction manifold sand and piles up husky stifled probability occurs, and in cleaning work after ongoing operations completes, also cleaning fluid cylinder inside and suction manifold is convenient to, after tilting with water, raffinate can conflux along tipping tube automatically, hydrops can not occur.Product of the present invention is by the structural design of advantages of simple, the recurrent suction of reciprocating plunger pump can be solved not enough, the sand caused because sucking deficiency is avoided to block up, inhale the accidents such as sky, water attack, effectively improve the working life of hydraulic end of plunger pump parts, and because be tilting, residual liquid material flows to the mouth of pipe because of deadweight, clears up fluid end and suction manifold after being convenient to operation, the quality of maintaining after raising operation and efficiency.
