Abstract
The utility model belongs to the intake manifold field of a multi-cylinder reciprocation pump, and particularly relates to a reducing intake manifold. The reducing intake manifold comprises a manifold body, wherein a plurality of branching exhaust ports are arranged in the manifold body, the sectional area of the manifold body which each branching exhaust port corresponds to changes step by step, and namely increases step by step or narrows step by step. In design, the size of the section of the manifold which the exhaust port at the tail end corresponds to is confirmed according to the requirements of intake flow of a liquid cylinder (the liquid cylinder takes in liquid at last) at the tail end, the sectional area of the manifold increases forwards step by step, and therefore liquid pressure of all liquid cylinder intake ports (connected with the branching exhaust ports) is identical. The reducing intake manifold is simple in structure, reasonable in design, capable of enabling each liquid cylinder of the multi-cylinder reciprocation pump to take in sufficient fluids, reduces cavitation, enables operation of the pump to be stable, reduces consumption, and prolongs service life.
Description
Technical field
The utility model belongs to the suction manifold field of multi cylinderpump, is specially a kind of reducing intake manifold.
Background technique
Use in the using process of slurry pump and multi-cylinder reciprocating working pump in the oil field, often can hear to have unusual sound of movement in valve pocket or the fluid cylinder, galloping, valve seat valve body wearing and tearing aggravation.This situation probably is because suction is inhomogeneous, causes cavitation phenomenon to cause.Because in the process that sucks fluid, first fluid cylinder can receive sufficient fluid, and the fluid cylinder of back might not get access to enough fluids, causes to find time to produce bubble, enters valve pocket and causes undesired abnormal sound and wearing and tearing.Patent of the present invention will address this problem.
Summary of the invention
It is a kind of reasonable in design and can make each fluid cylinder can both suck the reducing intake manifold of sufficient fully loaded fluid that the utility model provides, and solves in the prior art and produce bubble because finding time, and enters the problem that valve pocket causes undesired abnormal sound and wearing and tearing.
Its technological scheme is: comprise the manifold body, which is provided with a plurality of branch row outlets; The sectional area that described each branch row exports corresponding manifold body changes step by step, namely increases step by step or dwindles.During design, can be by the inhalation flow requirement of least significant end fluid cylinder (being drawn at last the fluid cylinder of fluid), determine the cross-sectional sizes of terminal exhaust port institute respective manifold, increase step by step forward the section area of manifold, so that equate at the fluid pressure of each fluid cylinder suction port (being connected with the branch row outlet).
The utility model is simple in structure, reasonable in design, can make each fluid cylinder of multi cylinderpump suck the sufficient fluid that satisfies, and reduces the generation of cavitation erosion, makes the pump running more steady, reduces the wastage, and increases the service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, manifold house steward, 2, branch row outlet
Embodiment
The present invention is described further below in conjunction with Figure of description and specific embodiment.
A kind of reducing intake manifold comprises manifold body 1, and its sectional area is from left to right successively less, is provided with successively a plurality of branch row outlets 2 on the manifold body 1.Wherein the branch row of the low order end sectional area that exports 2 corresponding manifold bodys 1 is determined by the inhalation flow requirement of least significant end fluid cylinder (being drawn at last the fluid cylinder of fluid), then increase step by step forward the section area of manifold, thereby so that equate at the fluid pressure of each fluid cylinder suction port (being connected with the branch row outlet), make each fluid cylinder of multi cylinderpump suck the sufficient fluid that satisfies, reduce the generation of cavitation erosion, make the pump running more steady, reduce the wastage, increase the service life.
