Abstract
The invention provides a liquid ring pump blade wheel, and relates to the technical field of water pump accessories. The liquid ring pump blade wheel is characterized in that the outer side of the hub (1) is provided with a plurality of long blades (2), short blades (3) are arranged between the adjacent two long blades (2), and the short blades (3) and the long blades (2) are fixedly connected through reinforced rib plates (4). According to the present invention, the short blades are additionally arranged, such that the secondary flow in the blades can be effectively inhibited, the jet flow wake strength of the blade outlet can be weakened, the influence of the limited blade number can be effectively weakened while the excretion coefficients at the outlet and the inlet of the gas suction zone and the gas discharge zone are not reduced, the blade wheel efficiency is increased, and the suction performance of the liquid ring vacuum pump and the compressing performance of the liquid ring vacuum pump adopted as the compressor can be improved.
Description
Technical field:
The present invention relates to water pump accessory technical field, be specifically related to a kind of water-ring pump impeller.
Background technique:
Water-ring pump in the course of the work inside is complicated gas liquid two-phase flow, and water, as the intermediate medium of energy transferring, exists complicated Secondary Flow in pump in working procedure, causes the efficiency of water-ring pump lower.The present invention improves the efficiency of water-ring pump by special impeller, improves it and sucks and compression performance.
Because water-ring pump inside exists complicated Secondary Flow structure, the object of the invention is to the Secondary Flow structure improved in water-ring pump, improve the efficiency of water-ring pump, improve suction performance and compression performance.
Summary of the invention:
The object of this invention is to provide a kind of water-ring pump impeller, the Secondary Flow that it can be drawn up in blade effectively by increasing short blade, weaken the jet tail intensity of blade exit, the excretion coefficient of air-breathing district and exhaust area import and export is not reduced while the impact effectively weakening the limited number of blade, improve the efficiency of impeller, improve the suction performance of liquid-ring vacuum pump and compression performance when using as compressor.
In order to solve the problem existing for background technique, the present invention is by the following technical solutions: it comprises wheel hub, linear leaf, short blade, reinforcement gusset, the arranged outside of described wheel hub has several linear leaf, be provided with short blade between two adjacent linear leafs, short blade is fixedly connected with linear leaf by strengthening gusset.
Beneficial effect of the present invention: control is optimized to gas liquid two-phase flow in pump by the structure improving impeller, blade design is become deviated splitter vane form, this invention is the improvement on traditional horizontal double-sucking type water-ring pump basis, and only improves the structure of impeller.The Secondary Flow that it can be drawn up in blade effectively by increasing short blade, weaken the jet tail intensity of blade exit, the excretion coefficient of air-breathing district and exhaust area import and export is not reduced while the impact effectively weakening the limited number of blade, improve the efficiency of impeller, improve the suction performance of liquid-ring vacuum pump and compression performance when using as compressor.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of Fig. 1 of the present invention.
Reference character: wheel hub-1, linear leaf-2, short blade-3, reinforcement gusset-4.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1-2, this embodiment is by the following technical solutions: it comprises wheel hub 1, linear leaf 2, short blade 3, strengthens gusset 4, the arranged outside of described wheel hub 1 has several linear leaf 2, be provided with short blade 3 between two adjacent linear leafs 2, short blade 3 is fixedly connected with linear leaf 2 by strengthening gusset 4.
Described short blade 3 designs in the half of inlet's circumferencial direction according to linear leaf 2 pitch angle, the radius of short blade 3 inlet side is got according to the mean value of linear leaf 2 inlet radius and exit radius, and the position of outlet port short blade 3 circumferencial direction is also designed according to the half of linear leaf 2 pitch angle.The vane type line of short blade 3 and the outlet section of linear leaf 2 completely the same, the load that short blade 3 bears is less, and has the effect strengthening gusset, and the thickness of short blade 3 can be designed to 4mm, better can retrain the flowing in blade, simultaneously less on the excretion coefficient impact of blade.
The beneficial effect of this embodiment: control is optimized to gas liquid two-phase flow in pump by the structure improving impeller, blade design is become deviated splitter vane form, this invention is the improvement on traditional horizontal double-sucking type water-ring pump basis, and only improves the structure of blade.The Secondary Flow that it can be drawn up in blade effectively by increasing short blade, weaken the jet tail intensity of blade exit, the excretion coefficient of air-breathing district and exhaust area import and export is not reduced while the impact effectively weakening the limited number of blade, improve the efficiency of impeller, improve the suction performance of liquid-ring vacuum pump and compression performance when using as compressor.
The above is only in order to illustrate technological scheme of the present invention and unrestricted, other amendment that those of ordinary skill in the art make technological scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
