Abstract
The utility model provides an impeller of water pump belongs to mechanical technical field. It has solved the current lower problem of impeller of water pump during operation pressure. This impeller of water pump including being cylindrical body, being equipped with the axis that a plurality of main lobe pieces and main lobe piece used the body and evenly setting up as the center on the lateral wall of body, the main lobe piece is the heliciform, and the upper end of main lobe piece has a current -limiting portion that can limit the rivers axial and up move, and current -limiting portion is parallel arrangement to the side of the going up of slice and its lateral wall and body. This impeller of water pump has the cavity lateral wall that can make the pump body and has the advantage of great pressure.
Description
Technical field
The utility model belongs to pump technology field, relates to the impeller of a kind of impeller, particularly water pump.
Background technique
Water pump is conveying liquid or the machinery making fluid pressurization.It sends the mechanical energy of prime mover or other external energies to liquid, liquid energy is increased, be mainly used to conveying liquid and comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The types such as volume water pump, vane pump can be divided into according to different working principles.Displacement pump utilizes the change of its swept volume of a single chamber to carry out transferring energy; Vane pump utilizes the interaction of rotary vane and water to carry out transferring energy, has the types such as centrifugal pump, axial-flow pump and mixed flow pump.
Impeller is one of parts important in water pump.A kind of water pump vane (application number: 201220521797.6) disclosed in Chinese patent literature, comprise choma cover, front shroud, back shroud and spacer, choma cover is enclosed within the suction port of front shroud, back shroud is connected with spacer, between front shroud and back shroud, be provided with blade, also comprise a tapered sleeve, this tapered sleeve is positioned at spacer, spacer spins one by tapered sleeve compress shrink and be fixed on the impeller nut on pump shaft, the outer end of described blade is provided with blade.But the blade of this impeller is common guide vane, operationally, all the time toward the axial drainage of impeller, the hydraulic pressure in the housing of the therefore pump housing is not ideal enough.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of impeller that the cavity wall of the pump housing can be made to have the water pump of larger pressure.
The purpose of this utility model realizes by following technical proposal: the impeller of water pump, comprise the body in column, the sidewall of described body is provided with some primary blades and described primary blades is evenly arranged centered by the axis of described body, it is characterized in that, described primary blades in the shape of a spiral, the upper end of described primary blades has the restrictor that can limit the axial up movement of current, described restrictor in the form of sheets and the upper side of its sidewall and described body be arranged in parallel.
The waterexit end of installing the water pump of this impeller needs the sidewall being arranged on housing.Operationally, the water of the feed-water end of water pump is inhaled by the primary blades that rotates through of body in the pump housing, because the upper end of primary blades has restrictor, restrictor in the form of sheets and be arranged in parallel with the upper side of body, therefore restrictor can guide current toward the wall flow of the cavity of the pump housing, avoid making the current in the pump housing continue to prolong the axially past interior movement of body, make the sidewall of the housing of the pump housing have larger hydraulic pressure.
In the impeller of above-mentioned water pump, be equipped with auxiliary blade between two adjacent primary blades, the height of described auxiliary blade is less than the height of described primary blades.By arranging auxiliary blade, adding water conservancy diversion effect, enabling this impeller realize larger working pressure.
In the impeller of above-mentioned water pump, the thickness of described primary blades progressively diminishes from its lower end toward upper end.The thickness of primary blades progressively diminishes from its lower end toward upper end, has rational in infrastructure and flow conductivity good advantage.
In the impeller of above-mentioned water pump, the width of described auxiliary blade is less than the width of described primary blades.
In the impeller of above-mentioned water pump, the impeller of this water pump adopts aluminum alloy material integrated formed structure.This impeller adopts aluminum alloy material integrated formed structure, has lighter in weight and not perishable, makes the advantage that working life is longer.
Compared with prior art, the impeller of this water pump has the following advantages:
1, restrictor can guide current toward the wall flow of the cavity of the pump housing, avoids making the current in the pump housing continue to prolong the axially past interior movement of body, makes the sidewall of the housing of the pump housing have larger hydraulic pressure;
2, by arranging auxiliary blade, adding water conservancy diversion effect, enabling this impeller realize larger working pressure;
3, the thickness of primary blades progressively diminishes from its lower end toward upper end, has rational in infrastructure and flow conductivity good advantage.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the impeller of this water pump.
In figure, 1, body; 2, primary blades; 3, restrictor; 4, auxiliary blade.
Embodiment
Be below specific embodiment of the utility model and by reference to 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, the impeller of water pump, comprise the body 1 in column, the sidewall of body 1 is provided with some primary blades 2, primary blades 2 is evenly arranged centered by the axis of body 1, in the shape of a spiral, the upper end of primary blades 2 has the restrictor 3 that can limit the axial up movement of current to primary blades 2, restrictor 3 in the form of sheets and the upper side of its sidewall and body 1 be arranged in parallel.
Be equipped with auxiliary blade 4 between two adjacent primary blades 2, the height of auxiliary blade 4 is less than the height of primary blades 2.The thickness of primary blades 2 progressively diminishes from its lower end toward upper end, has rational in infrastructure and flow conductivity good advantage.The width of auxiliary blade 4 is less than the width of described primary blades 2.
This impeller adopts aluminum alloy material integrated formed structure, has lighter in weight and not perishable, makes the advantage that working life is longer.
The waterexit end of installing the water pump of this impeller needs the sidewall being arranged on housing.Operationally, the water of the feed-water end of water pump is inhaled by the primary blades 2 that rotates through of body 1 in the pump housing, upper end due to primary blades 2 has restrictor 3, restrictor 3 in the form of sheets and be arranged in parallel with the upper side of body 1, therefore restrictor 3 can guide current toward the wall flow of the cavity of the pump housing, avoid making the current in the pump housing continue to prolong the axially past interior movement of body 1, the sidewall of the housing of the pump housing is made to have larger hydraulic pressure by arranging auxiliary blade 4, add water conservancy diversion effect, enable this impeller realize larger working pressure.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as body 1, primary blades 2, restrictor 3, auxiliary blade 4 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
