Abstract
The utility model relates to a guide impeller, comprising a guide shell and an impeller. The impeller is uniformly provided with 6-12 impeller blades, each impeller blade is twisted, inlet mounting angles of the impeller blade are within 10-40 DEG, the thicknesses of the impeller blades are within 1-4mm, wrap angles of the impeller blades are within 75-150 DEG, and outlet mounting angles of the impeller blades are within 15-65 DEG. The guide shell is uniformly provided with 8-14 guide shell blades, each guide shell blade is twisted, inlet angles of the guide shell blades are within 10-50 DEG, outlet angles of the guide shell blades are within 60-90 DEG, wrap angles of the guide shell blades are within 70-120 DEG, and the thicknesses of the guide shell blades are within 1-5mm; and the impeller is arranged in the guide shell, a protruded part in the guide shell is matched with a groove part of the impeller, and the impeller blades are arranged on the other surface opposite to the groove part. The guide impeller disclosed by the utility model has a simple structure, and the impeller blades are arranged on the other surface opposite to the groove part so that the hydraulic power is improved; and under the condition that the lift is changeless, the power is reduced, the efficiency is improved and the energy source is saved.
Description
Technical field
The utility model relates to a kind of petroleum pump blade guiding wheel, particularly a kind of blade guiding wheel that is used for submersible electric pump.
Background technique
Blade guiding wheel is the critical piece of submersible electric pump, because the blade of impeller is arranged in the groove of leading shell, the submersible electric pump that causes using at present is when the flow excursion optimal working point; Make impeller produce very big axial force; Cause very quick-wearing of impeller, cause hydraulic performance to reduce, power raises under the situation that does not have to change at lift; Not only reduced manufacturing efficiency, also wasted energy.
Summary of the invention
The utility model provides a kind of simple in structure for solving the technical problem that exists in the known technology, can improve the blade guiding wheel of hydraulic performance.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of blade guiding wheel; Comprise and lead shell and impeller, evenly be provided with 6～12 pieces of impeller blades on the said impeller, said impeller blade be shaped as twisted shape; The inlet laying angle of said impeller blade is 10～40 °; The thickness of said impeller blade is 1～4mm, and the cornerite of said impeller blade is 75～150 °, and the outlet laying angle of said impeller blade is 15～65 °; The said shell blade of leading of leading shell is a twisted shape; 10～50 ° of the said Inlet cone angles of leading the shell blade, said 60～90 ° of the shell blade outlet angles of leading, said cornerite of leading the shell blade is 70～120 °; The said quantity of leading the shell blade is 8～14 pieces and is uniformly distributed with that said thickness of leading the shell blade is 1～5mm; Said impeller is positioned at leads shell, and said jut of leading in the shell matches with the groove part of impeller, makes the opening of impeller be communicated with the opening of leading shell, and said impeller blade is positioned at the another side relative with groove part.
Advantage and the good effect that the utlity model has are: the utility model is simple in structure, and impeller blade is positioned at the another side relative with groove part, and hydraulic performance is improved, and has reduced power under the situation that does not have to change at lift, has improved efficient, has practiced thrift the energy.
