Abstract
The utility model relates to centrifugal pump water flow lead-in plates.Water flow lead-in plate is equipped at pump intake, it is plate that water flow, which introduces prelaminar part, and water flow introduces prelaminar part and is fixed on the inner wall of pump intake, and it is tubaeform that water flow, which introduces postlaminar part,.When liquid is flowed into from pump intake, water flow lead-in plate plays drainage guiding role to liquid, and liquid flow direction is corresponding with impeller channel, and liquid stabilising enters in impeller to be thrown away by centrifugation.
Description
Technical field
The utility model relates to be centrifuged pump technical field, it is specifically related to a kind of centrifugal pump water flow lead-in plate.
Background technique
The impeller of centrifugal pump is that the energy of prime mover is passed to the liquid in pumping by the effect of centrifugal force, increases liquid
Acceleration and pressure, promote to pump interior liquid and discharge, and the liquid in inlet ductwork, which is sucked into, to be come.The liquid flow entered from pump intake
Fast fast, fluid and impeller hub are hit, fluid splash, therefore liquid flows to disorder at impeller suction, affect liquid entrance
In impeller channel, pump performance is reduced.
Utility model content
Utility model aims to solve the above problems, and water flow lead-in plate is arranged in pump intake, rushes liquid not
In the case where hitting, even into impeller channel, pump performance is improved.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
Centrifugal pump water flow lead-in plate is equipped with impeller in the pump chamber at centrifugal pump inlet rear portion, is equipped with and pumps out in upper impeller
Mouthful, the blade of the impeller includes front shroud, back shroud, and the impeller of impeller internal is formed between front shroud, back shroud and blade
Runner, portion is water sucking mouth to impeller channel before the impeller, and impeller channel is water outlet in impeller diameter direction, which is characterized in that
Water flow lead-in plate is equipped at pump intake, it is plate that water flow, which introduces prelaminar part, and water flow introduces the inner wall that prelaminar part is fixed on pump intake
On, water flow introduce postlaminar part be it is tubaeform, water flow introduces postlaminar part and corresponds to the wheel hub of impeller, water flow lead-in plate back curve direction
Consistent with the bending of impeller channel, water flow lead-in plate rear edge corresponds to water sucking mouth.
Compared with prior art, the utility model advantageous effects are as follows:
Liquid is flowed into from pump intake, and water flow lead-in plate plays drainage guiding role to liquid, introduces postlaminar part in water flow
Under guiding, liquid flow direction bends, and liquid flow direction is corresponding with impeller channel, and liquid stabilising enters in impeller by centrifugal drying
Out.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

311, back shroud 312 and blade 31 form the impeller channel 313 of impeller internal, and impeller channel 313 is water suction in 3 front of impeller
Mouth 314, impeller channel 313 are water outlet 315 in 31 diametrical direction of impeller, and design feature is, water is equipped at pump intake 1
Lead-in plate 5 is flowed, 5 front of water flow lead-in plate is plate, and 5 front of water flow lead-in plate is fixed on the inner wall of pump intake 1, and water flow introduces
5 rear portion of plate be it is tubaeform, 5 rear portion of water flow lead-in plate corresponds to the wheel hub 32 of impeller, 5 back curve direction of water flow lead-in plate and impeller
The bending of runner 313 is consistent, and 5 rear edge of water flow lead-in plate corresponds to water sucking mouth 314.
Liquid is flowed into from pump intake 1, and water flow lead-in plate 5 plays drainage guiding role to liquid, at 5 rear portion of water flow lead-in plate
Guiding under, liquid flow direction bend, liquid flow direction it is corresponding with impeller channel 313, liquid stabilising enter in impeller 3 by from
The heart is thrown away.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, retouching in above embodiments and description
