Abstract
The utility model provides a precision casting blade guide wheel structure comprising impellers and a guide shell, blades of the guide shell are of a three-dimensional structure, a blade inlet angle is 10 degrees-50 degrees, blade thickness is 1mm-5mm, a blade wrap angle is 70 degrees-120 degrees, a blade outlet angle is 60 degrees-90 degrees, and the number of the blades is 8-14. The impellers are of mixed-flow type, the number of blades is 5-12, the blades are of a three-dimensional structure, a blade inlet placing angle is 10 degrees-40 degrees, blade thickness is 1mm-4mm, a blade wrap angle is 75 degrees-160 degrees, and a blade outlet placing angle is 15 degrees-60 degrees. The precision casting blade guide wheel structure mainly relates to blade shape lines of the impellers and blade shaped lines of the guide shell, the impellers in a three-dimensional structure distorted shape improve the fluid performance, and head of an electric pump unit is enabled to be improved; and the blade inlet placing angle is larger than a relative speed fluid flow angle, namely, blade inlet area is increased, the fluid resistance loss is reduced, and the cavitation performance of the impellers and the guide shell is improved, and therefore shape line improvements of the impellers and the guide shell enable the blade outlet placing angle to be more reasonable, and efficiency does not lose while the head of the electric pump unit is improved.
Description
Technical field
The utility model belongs to the blade guiding wheel of oil field electric pump, particularly relates to a kind of smart casting blade guiding wheel structure.
Background technique
Blade guiding wheel is by impeller and lead shell and consist of, and is the accessory of most critical on the electric pump unit of oil field, and its performance determines the performance of unit, and that blade guiding wheel belongs to its consumption of easily damaged parts is maximum.
Along with the oil extraction intermediary and later stages are progressively moved towards in the oil field, the application of electric pump unit increases year by year, the life-span of blade guiding wheel more and more is subject to people's attention, especially " when exploiting 600-800 cube/day well liquid in the sleeve pipe (124 millimeters of internal diameters); owing to the flow excursion optimal working point, make impeller produce huge axial force and vibration, cause blade guiding wheel and leaf to lead very quick-wearing of pad; to shorten pump detection period, had a strong impact on oil recovery amount 51/2.
98 serial blade guiding wheel 600-800 cubes/day lift is low simultaneously, causes pump to nearly double with blade guiding wheel progression, and unit length lengthens, and cost increases; Since the skew of the operating mode of pump, the Efficiency Decreasing of blade guiding wheel, and the power draw of expanded motor increases the unit cost.
Summary of the invention
The utility model is for " the above-mentioned technical problem that sleeve pipe (124 millimeters of internal diameters) and 98 serial blade guiding wheels exist, and a kind of smart casting blade guiding wheel structure is provided that solves 5 1/2.
The utility model is taked following technological scheme for achieving the above object: this essence casting blade guiding wheel structure, comprise impeller and lead shell, feature is: described its blade of shell of leading is three-dimensional structure, the blade inlet angle is the 10-50 degree, vane thickness is the 1-5 millimeter, subtended angle of blade is the 70-120 degree, and blade outlet angle is the 60-90 degree, blade quantity 8-14 piece; Described impeller is mixed-flow, and blade quantity 5-12 piece, blade is three-dimensional structure, and it is the 10-40 degree that blade inlet is laid angle, and vane thickness is the 1-4 millimeter, and subtended angle of blade is the 75-160 degree, and it is the 15-60 degree that blade exit is laid angle.
The beneficial effects of the utility model and advantage are: this essence casting blade guiding wheel structure relates generally to impeller and leads the vane type line of shell, and the blade of three-dimensional structure twisted shape has improved fluid property, and the lift of electric pump unit is increased; The blade inlet laying angle increases than relative velocity flow angle, namely increased the blade inlet-duct area, reduced liquid resistance loss and improved impeller or led the cavitation erosion performance of shell, impeller makes outlet laying angle degree more reasonable with the improvement of leading the shell mould line, does not lose again efficient simultaneously at the lift that improves the electric pump unit.
