Noise.
Summary of the invention
In order to solve the deficiencies in the prior art, a kind of pump housing influent stream with guide flow noise elimination function of the utility model
Pipe.The pump housing influent stream pipe clever structure of the guide flow noise elimination function, design rationally, can effectively eliminate clamoring for centrifugal pump influent stream
It is noise.
According to technical solution provided by the utility model, a kind of pump housing influent stream pipe of guide flow noise elimination function, the water conservancy diversion disappears
The pump housing influent stream pipe of sound function includes pipe fitting ontology, and the pipe fitting ontology surrounds to form an influent stream channel, in the influent stream channel
Equipped with damper element；The damper element inner hollow forms noise elimination cavity, and the side wall of damper element is corrugated or corrugated, corrugated or
If forming arterial highway diversion trench in the side wall inner surfaces of corrugated damper element, the diversion trench is axially extended；The water conservancy diversion slot position
Interval is densely covered with deflector hole on the damper element side wall at the place of setting.
Further, the deflector hole is ellipse, round or rectangle.
Further, protuberance forms diversion division, the diversion division outward on the damper element side wall of the water conservancy diversion hole location
It is equipped with conduction hole, the conduction hole will be connected to by diversion division with deflector hole.
Further, the noise elimination cavity first end connection influent stream channel flow inlet, the second end of noise elimination cavity be connected into
Circulation road.
Further, the damper element is frustum type；From the first end of damper element to its second end, the section of damper element by
Taper contracting.
It is and existing from the above as can be seen that this centrifugal pump influent stream pipe provided by the utility model with noise elimination function
Technology, which is compared, has following advantages: the pump housing influent stream pipe clever structure of the guide flow noise elimination function, design rationally, can be effectively
It eliminates clamoring for centrifugal pump influent stream and is noise.

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the utility model is further described.Wherein identical components are presented with like reference characters.It needs
Illustrate, word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the side in attached drawing
To.The word "inner" used and "outside" refer respectively to the direction towards or away from geometric center of specific component.
A kind of pump housing influent stream pipe of guide flow noise elimination function, as shown in Fig. 1 ~ Fig. 3, the pump housing influent stream of the guide flow noise elimination function
Pipe includes pipe fitting ontology 1, and the pipe fitting ontology 1, which surrounds, forms an influent stream channel 2, is equipped with damper element 3 in the influent stream channel 2.
3 inner hollow of damper element forms noise elimination cavity 4, and the flow inlet 5 in the first end connection influent stream channel 2 of the noise elimination cavity 4 is eliminated the noise
The second end of chamber 4 is connected to influent stream channel 2.Damper element 3 is set to can be space-saving in the influent stream channel 2 while to noise elimination
Part 3 plays a protective role, and prevents exposed damper element 3 because falling off from the impact force of the fluid of all directions or shape
Become.
The side wall of the damper element 3 is corrugated or corrugated, is densely covered on the side wall of corrugated or corrugated damper element 3
Deflector hole 6, the deflector hole 6 are ellipse, round or rectangle.Corrugated or the side wall inner surfaces of corrugated damper element 3 are formed
Axially extending diversion trench 9, interval is densely covered with deflector hole 6, the water conservancy diversion on 3 side wall of damper element at 9 position of diversion trench
Slot 9 enables to damper element 3 to have good diversion effect, so that deflector hole 6 of the fluid from diversion trench 9 and thereon flows out.Together
When corrugated or the side wall of corrugated damper element 3 make damper element 3 have a good extensibility, increase the surface area of damper element 3,
Enable same volume fluid faster flow through damper element 3.And deflector hole 6 can be dispersed into damper element 3
Biggish fluid impingement force avoids fluid from concentrating impact pipe fitting inner wall, to effectively avoid issuing to clamor being noise
Protuberance forms diversion division 7 outward on 3 side wall of damper element at 6 position of deflector hole, and the diversion division 7 is equipped with
Conduction hole 8 is connected to by conduction hole 8, the diversion division 7 with deflector hole 6, so that fluid enters 3 noise elimination cavity of damper element from flow inlet 5
In, diversion division 7 is flowed through by the deflector hole 6 on the side wall of damper element 3, is finally flowed into influent stream channel 2 from conduction hole 8.
In order to avoid hindering fluid to enter the flow velocity in centrifugal pump influent stream pipe because increasing damper element 3, the damper element 3 is
Frustum type, and from the first end of damper element 3 to its second end, the section of damper element 3 gradually tapers up.The noise elimination of the frustum type
Part 3 can be improved the Fluid pressure in centrifugal fluid pump influent stream channel 2.
It should be understood by those ordinary skilled in the art that: the foregoing is merely specific embodiment of the utility model and
, it is not intended to limit the utility model, all any modifications within the purport of the utility model, made, change equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
