Abstract
The utility model provides a water pump impeller, which belongs to the field of mechanical technology, and solves the problems that an existing water pump has low lifting capacity and small application range. The water pump impeller comprises a blade and a disc-shaped wheel disc, wherein the center of the wheel disc is provided with a connecting hole which is run through by a driving shaft, the blade is fixed on the wheel disc through using the connecting hole as the center, the blade is in an arc flake and is distorted to have torsion resistance, and the torsion resistance is from 5 degrees to 7 degrees. The water pump impeller can increases the lifting capacity of the water pump, and leads the application range of a water pump to be wider.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of water pump, particularly a kind of water pump vane that can improve pump head.
Background technique
Water pump is widely used in daily life and industrial production, and lift is the increment of unit weight liquid from pump inlet to pump discharge place energy that water pump is pumped, and promptly water pump is pumped the liquid-column height of liquid, and lift is an important indicator of water pump.The impeller of tradition water pump is made up of blade and wheel disc, and blade is straight lamellar body, is the circumferential five equilibrium of aplysia punctata and is connected on the wheel disc, though this impeller is made simply, flowability is relatively poor to make that the lift of water pump is less.
At the problems referred to above, people have carried out various designs to water pump blade, have also used for reference the disclosed a kind of Nash hytor [application number: 01255173.2 of Chinese patent literature data; Notice of authorization number: CN2528974Y], it comprises pump case, pump cover and impeller, impeller is in the eccentric position of pump case, end face is provided with the intake and exhaust dish, impeller and motor coaxle, motor bearings axial compression location, intake and exhaust dish end face is provided with exhaust valve plate, mechanical seal is adopted in the sealing of axle, and it is streamlined that blade is front curve.The eccentric water ring that forms when impeller rotates makes the continuous cyclically-varying of interlobate volume, realizes air-breathing, compression and exhaust process.It is streamlined that people also are made into front curve according to this patent with the blade of water pump.
The front curve streamline vane of water pump can make hydraulic efficiency obtain certain raising like this, but few to the amplification of lift, and the lift of water pump is not high, thereby has influenced the using scope of water pump.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, and a kind of water pump vane that can improve pump head is provided.
The purpose of this utility model can realize by following technical proposal: a kind of water pump vane, the wheel disc that comprises blade and plate-like, the described disk center of taking turns has the attachment hole that passes for live axle, described blade is that center fixation is on described wheel disc with the attachment hole, it is characterized in that, curved sheet of described blade and leaf curling form has torsion, and described torsion is 5 ° to 70 °.
Torsion is the angle that blade turns over respect to the plane distortion, the curved sheet distortion of the blade of this water pump vane forms, and makes the hydraulic efficiency of impeller be greatly improved, and the flow that impeller drives water increases, improved the lift of water pump, water pump is applied widely like this.
In above-mentioned water pump vane, described wheel disc and blade are the integral type foundry goods.This water pump vane adopts integral cast to form sound construction, good operation stability.
Compared with prior art, the curved sheet distortion of the blade in this water pump vane forms, and makes the hydraulic efficiency of impeller be greatly improved like this, and has increased the flow of impeller drive water, has improved the lift of water pump, makes that the using scope of water pump is wide.
Description of drawings
Fig. 1 is the perspective view of this water pump vane.
Among the figure, 1, blade; 2, wheel disc; 21, attachment hole.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this water pump vane is made up of blade 1 and wheel disc 2.Wheel disc 2 is plate-like and wheel disc 2 centers have the attachment hole 21 that passes for live axle, and blade 1 is that center fixation is on wheel disc 2 with attachment hole 21.This water pump vane adopts integral cast to form, and wheel disc 2 and blade 1 are the integral type foundry goods, sound construction, good operation stability.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as blade 1, wheel disc 2, attachment hole 21 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
Claims (2)
1. water pump vane, the wheel disc (2) that comprises blade (1) and plate-like, described wheel disc (2) center has the attachment hole (21) that passes for live axle, described blade (1) is that center fixation is on described wheel disc (2) with attachment hole (21), it is characterized in that, curved sheet of described blade (1) and blade (1) distortion form has torsion, and described torsion is 5 ° to 70 °.
