Abstract
A kind of boiler water circulating pump with efficient diffuser, including the pump housing, diffuser；The diffuser is located at the pump housing water inlet；The diffuser includes water inlet connector, diffuser body, diffuser base；It is connected with below the water inlet connector below the diffuser body, the diffuser body and is connected with the diffuser base；The diffuser base center is vertically provided between several dispersion plates, two dispersion plates and forms dispersion slot；Longitudinal direction is provided with screen pack on each dispersion slot.Beneficial effects of the present invention are：（1）The water inlet connector, diffuser body and the diffuser base are coaxially disposed, and the stabilization of self structure is maintained to a certain extent；（2）Multiple dispersion slots can play a part of shunting to recirculated water, reduce the impact to the pump housing；（3）Screen pack serves the left and right of filtering sand and dust to a certain extent, it is to avoid sand and dust are to the blocking caused by dispersion slot.
Description
Technical field
The present invention relates to stove water pump field, and in particular to a kind of boiler water circulating pump with efficient diffuser.
Background technology
In overcritical big-and-middle-sized unit, in order to ensure that flow velocity is provided with again boiler in water-cooling wall in startup and underload
Circulating pipe system, boiler water circulating pump is to be located to bear one kind that HTHP makes medium make forced flow in boiler evaporating system
Big flow, low lift centrifugal pump of single stage type.Wherein impact, typically passed in and out in boiler water circulating pump in recirculated water in order to reduce pump blade
The mouth of a river is installed by one diffuser, diffuser（Also known as diffusional filter or diversion filter）It is commonly used in the suction of water circulating pump
Mouthful, instead of elbow, guide functions are played to water, so as to protect pump leaf, the service life of water pump is extended 2-3 times.Recirculated water
In sand and dust diffuser can be caused to block, long can influence the use of whole circulating pump, the stability of diffuser self structure
The use of whole circulating pump is directly affected, often changing diffuser can cause cost to increase, and also waste time and energy.
The content of the invention
The invention aims to overcome deficiency of the prior art to be followed there is provided a kind of stove water with efficient diffuser
Ring pump, in order to solve the above technical problems, the technical scheme is that：
A kind of boiler water circulating pump with efficient diffuser, including the pump housing, diffuser；The diffuser is intake located at the pump housing
At mouthful；The diffuser includes water inlet connector, diffuser body, diffuser base；It is connected with below the water inlet connector
The diffuser base is connected with below the diffuser body, the diffuser body；The water inlet connector, diffuser sheet
Body and the diffuser base are coaxially disposed；
The diffuser base center is vertically provided between several dispersion plates, two dispersion plates and forms dispersion slot；
Longitudinal direction is provided with screen pack on each dispersion slot.
Further, diameter of the diffuser body close to described water inlet connector one end is slightly less than the diffuser sheet
Diameter of the body close to described diffuser base one end.
Beneficial effects of the present invention are：（1）The water inlet connector, diffuser body and the diffuser base are coaxially set
Put, the stabilization of self structure is maintained to a certain extent；（2）Multiple dispersion slots can play a part of shunting to recirculated water,
Reduce the impact to the pump housing；（3）Screen pack to a certain extent serves the left and right of filtering sand and dust, it is to avoid sand and dust are to scattered
Blocking caused by groove.
Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention；
Accompanying drawing 2 is diffuser structure schematic diagram.
Embodiment
To make to have a better understanding and awareness to architectural feature of the invention and the effect reached, to preferably
Embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in accompanying drawing 1 ~ 2, a kind of boiler water circulating pump with resistance to compression diffuser, including the pump housing 1, diffuser 2；The diffuser 2
Located at the water inlet of the pump housing 1, the diffuser 2 includes water inlet connector 21, diffuser body 22, diffuser base 23；
The lower section of water inlet connector 21 is connected with the diffuser body 22, and the lower section of diffuser body 22 is connected with the diffusion
Device base 23；
The center of diffuser base 23, which is vertically provided with to be formed between several dispersion plates 24, two dispersion plates 24, to be divided
Groove 25 is dissipated, the dispersion slot 25 can play a part of shunting to recirculated water, reduce the impact to the pump housing 1；Such as accompanying drawing 2
Shown, longitudinal direction, which is provided with, on each dispersion slot 25 only draws a screen pack 26 in screen pack 26, figure and illustrates, not
All screen packs 26 are drawn, the setting of the screen pack 26 reduces sand and dust into the dispersion slot to a certain extent
In 25, prevent the dispersion slot 25 from blocking and causing the operating efficiency of whole boiler water circulating pump.
The water inlet connector 21, diffuser body 22 and the diffuser base 23 are coaxially disposed, the diffuser sheet
Diameter of the body 22 close to described water inlet connector 21 one end is slightly less than the diffuser body 22 close to the diffuser base 23
The diameter of one end, maintains the stabilization of self structure to a certain extent.
Beneficial effects of the present invention are：（1）The water inlet connector, diffuser body and the diffuser base are coaxially set
Put, the stabilization of self structure is maintained to a certain extent；（2）Multiple dispersion slots can play a part of shunting to recirculated water,
Reduce the impact to the pump housing；（3）Screen pack to a certain extent serves the left and right of filtering sand and dust, it is to avoid sand and dust are to scattered
Blocking caused by groove.
It should be understood by those skilled in the art that, the present invention is not limited to the above embodiments, above-described embodiment and explanation
The principle of the simply present invention described in book, it is of the invention without departing from the spirit and scope of the present invention also to have various changes
Change and improve, these changes and improvements are both fallen within the range of claimed invention.The protection domain of application claims by
Appended claims and its equivalent are defined.
