Description
Technical field
It the utility model is related to a kind of pump accelerating tube.
Background technology
Pipeline is used to convey the fluids such as gas, liquid or gas-liquid mixed, and the application in fields such as water power, chemical industry is all quite wide
General, flow regime of the fluid in pipeline can be divided into laminar flow, transition flow and turbulent flow according to flow velocity.Laminar flow refers to when flow velocity is small
When, fluid layering flowing, mutual unmixed flow regime, also referred to as current stabilization or piece stream；Transition flow refers to when flow velocity is larger, flows
The streamline of body starts the flow regime for wavy swing occur, and its frequency swung and amplitude increase with the increase of flow velocity；
Turbulent flow refers to that streamline is no longer clearly apparent when flow velocity increases to very big, the small whirlpool in many of flow field, the destroyed shape of laminar flow
State, at this moment adjacent flow interlayer not only have slip, also mix, fluid at this moment makees irregular movement, has perpendicular to flow tube axis
The component velocity in direction produces, and this motion is referred to as turbulent flow, also known as sinuous flow, flow-disturbing or turbulent flow.Therefore, fluid flows in pipeline
When can be influenceed by itself flow regime and lose mechanical energy, particularly with the fluid in turbulence state, its mechanical power loss
It is bigger, cause fluid to produce larger pressure drop in the duct, so as to reduce flow velocity.
Traditional, people are by increasing transmission power, pipeline sets the design of tapered or inner-walls of duct smooth to improve
The kinetic energy of fluid, so as to keep fluid still to have larger flow velocity when flowing to pipe end, still, fluid makees irregular movement,
It can be influenceed by itself flow regime when being flowed in pipeline and lose mechanical energy, cause fluid to produce larger pressure in the duct
Drop, so as to reduce flow velocity.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model provides a kind of pump accelerating tube, and it mainly solves prior art
Middle fluid makees irregular movement, can be influenceed by itself flow regime when being flowed in pipeline and lose mechanical energy, cause fluid
Larger pressure drop is produced in the duct, the problem of so as to reduce flow velocity.
To achieve the above object, the utility model employs following technical scheme：A kind of pump accelerating tube, including body,
The body includes acceleration portion and is separately positioned on acceleration portion both ends being used for the first connecting portion that is connected with external screw-thread and the
Two connecting portions, the acceleration portion are cone-shaped, are provided with least one helical groove on acceleration portion madial wall, described first
Connecting portion is arranged on the larger water inlet of acceleration portion upper shed, and rectifier is provided with the first connecting portion.
Further, the rectifier includes toroidal shell, and the toroidal shell can relatively rotate with first connecting portion, institute
The axially middle part for stating toroidal shell is provided with connecting rod, and helical blade is provided between the connecting rod and toroidal shell, described
The direction of rotation of helical blade is identical with the direction of rotation of helical groove.
Further, the periphery in the acceleration portion is arranged with containment vessel.
Further, the section of the helical groove is V-type.
By using preceding solution, the beneficial effects of the utility model are：This pump passes through the first connection with accelerating tube
The delivery port of portion and water pump is connected, and acceleration portion is flowed into after rectifier rectification by the chaotic current that water pump accelerates, is added
The water that the helical groove set in fast portion flows into helical flow, forms regular flowing in the presence of helical groove
Direction, accelerate the flow velocity of water；Further, the helical blade that the water accelerated by water pump is hit on rectifier causes helical blade
Rotate, helical blade rotates and reacts on current so that chaotic current form spiral helicine flowing, are advantageous to current and are accelerating
Accelerate in portion, reduce pressure drop of the water in pipeline；Further, the containment vessel that the periphery face in acceleration portion is set is used to protect
Acceleration portion plays a protective role from external impact；Further, the section of helical groove is the spiral shell that V-type is advantageous to accelerate water
Eddy flow moves.
