Description
Technical field
The present invention relates to a kind of water impellers.
Background technique
Currently, in existing cooling tower reducing energy consumption engineering, usually be mounted on after the hydraulic turbine water inlet pipe and sprinkler pipe it
Between, water drives fan blade to rotate after turbine impeller does work, if power is inadequate, auxiliary force motor auxiliary fan blade is installed additional, due to cooling
After reaction turbine does work, pressure is lower water, and flow velocity reduces, so that cooling tower flow be caused to reduce, cooling effect is bad,
And if cooling water flow velocity reduces, flow will cause the pressure in entire circulating line in turn and rise after reducing, and finally makes water pump
Pressure increase, electric current rise, energy consumption increase, be more unfavorable for energy conservation.
Summary of the invention
The object of the present invention is to provide a kind of water impellers, can preferably increase displacement, save energy consumption.
To achieve the above object, a kind of water impeller provided by the present invention comprising core wheel and be distributed in the wheel
Several blades of core periphery, the blade include the influent side of the vacuum side of blade and the drain-side of the face of blade；Institute
The one side for stating the rotation direction of water impeller is the front of the blade；It is arc-shaped that the lower end of the drain-side is provided with section
Concave water repellent portion.
In above-mentioned water impeller, the water repellent portion is set to the bottom end of the drain-side, the top side in the water repellent portion
Connect with the bottom end side of the drain-side, the concave surface direction in the water repellent portion is with the blade just facing towards identical.
In above-mentioned water impeller, the axial direction of the axial direction of the blade and the core wheel is in an angle.
In above-mentioned water impeller, the angle is in 15 degree~45 degree.
In above-mentioned water impeller, the blade is in distorted shape.
In above-mentioned water impeller, the width in the water repellent portion is of same size with the blade.
In above-mentioned water impeller, the quantity of the blade is four.
A kind of water impeller provided by above-mentioned technical proposal, compared with prior art, its advantages include: draining leaf
When wheel rotation, water flow enters drain-side by influent side and is discharged, by the way that the arc-shaped concave water repellent portion in section is arranged in drain-side,
When water flow flow to drain-side with the rotation of water impeller, water flows through the concave surface hit water repellent portion and pass through water repellent portion and flows out,
To increase the speed of draining water flow, so that enlargement discharge, improves displacement in the case where same motor power, saves
Energy consumption.
Detailed description of the invention
Fig. 1 is one of the structural schematic diagram of water impeller of the invention；
Fig. 2 is the second structural representation of water impeller of the invention.
Wherein, 1- core wheel, 2- blade, 3- influent side, 4- drain-side, 5- water repellent portion.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Please refer to attached drawing 1-2, a kind of water impeller provided by the present invention comprising core wheel 1 and be distributed in the wheel
Several blades 2 of 1 periphery of core, the blade 2 include influent side 3 and the positive draining of the blade 2 at 2 back side of blade
Side 4；The one side of the rotation direction of the water impeller is the front of the blade 2；The lower end of the drain-side 4, which is provided with, to be cut
The arc-shaped concave water repellent portion 5 in face.
Based on above-mentioned technical characteristic, when the water impeller rotates, water flow enters the drain-side by the influent side 3
4 discharges, by the way that the arc-shaped concave water repellent portion 5 in section is arranged in the drain-side 4, when water flow is with the water impeller
Rotation when flowing to the drain-side 4, water flows through the concave surface hit the water repellent portion 5 and pass through the water repellent portion 5 and flows out, thus
The speed for increasing draining water flow, so that enlargement discharge, improves displacement in the case where same motor power, save energy
Consumption.
The water repellent portion 5 is set to the bottom end of the drain-side 4, the top side in the water repellent portion 5 and the drain-side 4
Bottom end side connect, the concave surface in the water repellent portion 5 towards with the blade 2 just facing towards identical；By by the water repellent
Portion 5 is set to the low side of the drain-side 4, increases flowing velocity when water flow and the water repellent portion 5 shock, further increases water
The drainage speed of stream, and increase the concave surface in the water repellent portion 5 always, by water flow towards the rotation direction with the water impeller
It is flow to the contact surface of concave surface Yu the water repellent portion 5, increases delivery flow.
The axial direction of the axial direction of the blade 2 and the core wheel 1 is in an angle, and the drain-side 4 is from the water impeller
Rotation direction is from top rake, so that the blade 2 and the core wheel 1 are at an angle, when water impeller rotation, water flow stream
When to the drain-side 4, reduces water and flow through out-of-date resistance, improve drainage efficiency, be different from the leaf that traditional blades are vertically arranged
Wheel.
The angle is in 15 degree~45 degree, selects corresponding angle according to different situations, improves drainage efficiency.
The blade 2 is in distorted shape, by making the blade 2 be in the distortion of radian, and towards the rotation of the water impeller
Direction distortion, the drainage efficiency of water flow when improving water impeller rotation, so that water flow is by the blade 2 in distorted shape
When, flowing velocity is higher, and resistance is smaller.
The width in the water repellent portion 5 is of same size with the blade 2, by making the water repellent portion 5 and the blade 2
It is of same size, the water repellent portion 5 is improved to the acceleration drainability of water flow, further increases drainage efficiency.
The quantity of the blade 2 is four, and the 2 quantity demand of the blade drained needed for meeting reduces cost.
