Abstract
A thrust pump comprises a pump housing (1), a pump shaft (2), an impeller disk (3) and blades (4) and is characterized in that the distance between an outlet end (A) of the previous blade in the blades (4) and an inlet end (B) of the later blade is less than 1/5 of a marginal arc of the impeller disk (3) between the outlet end (A) of the previous blade and an outlet end (C) of the adjacent later blade. The thrust pump is simple in structure, simple to manufacture and convenient to mount, and greatly reduces energy consumption. The conversion efficiency of a fan or the pump is improved, and the thrust pump is good in energy conservation effect, and is applicable to conveying fluid substances such as liquid and gas.
Description
Technical field
The present invention relates to a kind of pump, relate in particular to a kind of thrust pump, belong to the fluid machinery technical field.
Background technique
Common blower fan and pump efficiency are very low, and its main cause is: they are mostly to utilize centrifugal principle, make fluid high-speed throw away blade, high-velocity fluid becomes high-pressure liquid and flows out pump case in the pressure chamber, therefore the rate of flow of fluid in pump case is very fast, and energy loss is also very large, and efficient is very low.
Summary of the invention
The objective of the invention is for existing volute pump complex structure, conversion efficiency is lower, and the defective that energy consumption is larger and deficiency provide a kind of simple in structure, and volume is little, and is easy for installation, and conversion efficiency is higher, a kind of thrust pump that energy consumption is less.
For achieving the above object, technical solution of the present invention is: a kind of thrust pump, comprise pump case, pump shaft, the impeller plate and blade, the distance between the last blade exit end in described blade and a rear blade entrance point is less than 1/5 of impeller plate edge arc length between last blade exit end and an adjacent rear blade exit end.
Described blade is circular arc type, its radius of arc be a rear blade entrance point and a rear blade exit end divide be clipped to impeller plate distance of shaft centers from mean value, a rear blade entrance point is the closest approach of the last blade exit end of the upper distance of blade place circle.
Described blade and impeller plate inner and outer surface all scribble low-surface-energy material.
The invention has the beneficial effects as follows:
The present invention is simple in structure, makes simply, and is easy for installation, makes energy loss greatly reduce, and the present invention is conducive to improve the conversion efficiency of blower fan or pump, and good energy-conserving effect can be applicable to the conveying of the flowing materials such as liquid, gas.
Description of drawings
Fig. 1 is plan view of the present invention.
Fig. 2 is the structural representation of the impeller plate of the present invention and blade.
In figure: pump case 1, pump shaft 2, the impeller plate 3, blade 4, last blade exit end A, a rear blade entrance point B, a rear blade exit end C.
Embodiment
The present invention is described in further detail below in conjunction with description of drawings and embodiment.
Referring to Fig. 1, Fig. 2, a kind of thrust pump of the present invention, comprise pump case 1, pump shaft 2, the impeller plate 3 and blade 4, it is characterized in that: the distance between the last blade exit end A in described blade 4 and a rear blade entrance point B is less than 1/5 of the impeller plate 3 edge arc length between last blade exit end A and an adjacent rear blade exit end C.
Described blade 4 is circular arc type, its radius of arc be a rear blade entrance point B and a rear blade exit end C divide be clipped to the impeller plate 3 distances of shaft centers from mean value, a rear blade entrance point B is the closest approach of the last blade exit end A of the upper distance of blade place circle.
Described blade 4 and the impeller plate 3 inner and outer surface all scribble low-surface-energy material.
On the pump shaft 2 of pump case 1 inboard, the impeller plate 3 is installed, evenly is provided with 2-4 blade 4 on the circumference of the impeller plate 3.Blade 4 is circular arc type, its radius of arc be a rear blade entrance point B and a rear blade exit end C divide be clipped to the impeller plate 3 distances of shaft centers from mean value, a rear blade entrance point B is the closest approach of the last blade exit end A of the upper distance of blade place circle.Distance between last blade exit end A in blade 4 and a rear blade entrance point B is less than 1/5 of the impeller plate 3 edge arc length between last blade exit end A and an adjacent rear blade exit end C.
working principle of the present invention and process are as follows: the impeller plate 3 is High Rotation Speed under driven by motor, the impeller plate 3 centers produce negative pressure, fluid in inlet tube is inhaled in the impeller plate 3, the impeller plate 3 with respect to High Rotation Speed, fluid in the impeller plate 3 is owing to keeping static inertial force " to break through " runner with identical speed opposite direction, simultaneously, due to the blade entrance point relatively near the impeller plate 3 edges, at the uniform velocity wait a moment from the entrance point to outlet end speed ground of whole circular arc type blade will be somebody's turn to do in the fluid-propelled pressure chamber of " breaking through " runner, then flow out pump case 1 through outer pipe, the impeller plate 3 is completed acting.In whole process, the absolute velocity of fluid is less, and blade 4 and the impeller plate 3 inner and outer surface all scribble low-surface-energy material, makes energy loss greatly reduce, the present invention is conducive to improve the conversion efficiency of blower fan or pump, conversion efficiency can be improved 20%-30%.
Claims (3)
1. thrust pump, comprise pump case (1), pump shaft (2), the impeller plate (3) and blade (4), it is characterized in that: the distance between the last blade exit end (A) in described blade (4) and a rear blade entrance point (B) is less than 1/5 of the impeller plate (3) edge arc length between last blade exit end (A) and an adjacent rear blade exit end (C).
2. a kind of thrust pump according to claim 1, it is characterized in that: described blade (4) is circular arc type, its radius of arc be a rear blade entrance point (B) and a rear blade exit end (C) minute be clipped to the impeller plate (3) distance of shaft centers from mean value, a rear blade entrance point (B) is the upper closest approach apart from last blade exit end (A) of blade place circle.
3. a kind of thrust pump according to claim 1, it is characterized in that: described blade (4) and the impeller plate (3) inner and outer surface all scribble low-surface-energy material.
