Description
Technical field
The utility model relates to axial-flow pump technical field, particularly relates to a kind of high-lift helical blade impeller.
Background technique
Axial-flow pump impeller mostly in the market is stainless steel material and makes, for being arranged vertically between its impeller blade and choma, in the process of work, in the process that its impeller rotates with pump shaft, centrifugal motion is there is in fed sheet of a media near impeller, cause the ability of impeller fed sheet of a media to decline, particularly carry the media capabilities that air content is high lower; At exploitation high gas-oil ratio (HGOR) oil reservoir, when gas-liquid two-phase fluid MEDIA FLOW is when the impeller of conventional vane pump, the liquid phase that density is larger is thrown out of under the influence of centrifugal force, the gas phase that density is less is then aggregated in the low pressure area near impeller hub entrance, form dead band, along with the dead space volume in the increase impeller of vane pump operating time increases at leisure, final whole runner will be filled by gas phase completely, causes pump to lose the job ability.
Model utility content
The purpose of this utility model is to provide a kind of high-lift helical blade impeller, solves transport pump ability, fed sheet of a media in prior art near impeller, there is centrifugal motion problem;
The technological scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of high-lift helical blade impeller, comprise pump shaft cover, choma and blade, described choma is sleeved on pump sleeve end, and choma is provided with blade, described blade is helical, the spiral cornerite of described blade is 200-220 °, and the stagger angle of described blade is 10-12 °, and the exit installation angle of blade is 14-18 °, described choma is conical, and the cone angle of choma is 6-10 °, the width of described choma is 40-52mm, and choma evenly has multiple keyhole;
On the basis of technique scheme, the utility model can also do following improvement:
Further, described blade is 3-5 sheet, adopts the beneficial effect of this step to be to make pump have enough flow areas, ensures to have enough flows;
Further, described choma end has groove, and the degree of depth of described groove is 1-2mm, adopts the beneficial effect of this step to be when mounted, ensures that impeller and other assembling sets leave gap, prevents friction, impeller is produced to the efficiency damaging and affect impeller work;
Further, on described blade, the number of degrees of the established angle of each point are wave-like type distribution, adopt the beneficial effect of this step to be ensure that the ability of high air content medium carried by axial-flow pump;
Further, the linearly rule change of described vane thickness, the thickness of blade according to arrive little distribution more from small to large, blade outlet and entrance face thinner, adopt the beneficial effect of this step to be the dissection of increase to bubble;
The utility model adopts the impeller be in tilted layout, the blade of impeller tilts along pump shaft moving direction, reducing fed sheet of a media with the centrifugal motion in wheel rotation process, by controlling the slanted angle between impeller and choma, improving conveying capacity when impeller carries high air content;
The beneficial effects of the utility model are:
1. the utility model is by controlling the inclination angle along pump shaft moving direction between blade and choma, improves the ability that high air content medium carried by axial-flow pump, solves axial-flow pump well and carries the problem that high air content media capabilities is low;
2. the utility model choma adopts cone structure, and fluid is entered by path end face, and bigger diameter end surface current goes out, and through the fluid of supercharging, along with the minimizing of runner area of passage, pressure increases further, and pressurized effect is more remarkable compared with original cylindrical choma;
3. blade of the present utility model outlet and entrance face blade thinner, the importing of thin blade for fluid and the dissection to bubble will show increase.
