Abstract
The utility model provides a blade wheel and guide wheel structure of an electric submersible pump. The blade wheel and guide wheel structure comprises a blade wheel and a guide wheel, wherein an oil channel and a plurality of blades are arranged on each of the blade wheel and the guide wheel; the blade wheel is connected with the guide wheel in a matched mode; a plurality of pressure balance holes are formed in the end face of the blade wheel, which is in contact with the guide wheel; a first assembly slot and a second assembly slot are formed in the blade wheel and positioned at a joint of the blade wheel and the guide wheel; a first abrasion reduction pad is arranged in the first assembly slot; and a second abrasion reduction pad is arranged in the second assembly slot. In the blade wheel and guide wheel structure, the pressure balance holes are formed in the end face of the blade wheel, which is in contact with the guide wheel, so that pressure intensity on the contact end face is the same as that at the bottom of the blade wheel, and the friction between the blade wheel and the guide wheel is further reduced; the blade wheel rotates flexibly; the abrasion speed of the blade wheel and the abrasion speed of the guide wheel are reduced; the service life of the electric submersible pump is prolonged; and the oil yield is increased.
Description
Technical field
The utility model belongs to the submersible electric pump field, is specifically related to a kind of blade guiding wheel structure of submersible electric pump.
Background technique
China has had the history in 30 years so far since 1981 introduce the submersible electric pump technology, submersible electric pump has obtained extensive use as important mechanical oil recovery equip ment in the oil field.Even to this day, submersible electric pump has developed into no longer and has existed with single equipment, but exists with a whole set of system.During the driven by motor impeller high speed rotating of submersible electric pump; Be filled in the interior liquid of impeller under action of centrifugal force, get rid of around impeller, pressure and speed are increased simultaneously through impeller channel; Just obtain certain lift of pump after the stack of pump one by one, underground well liquid is delivered to ground pump station.But the blade guiding wheel structure rate of wear of existing submersible electric pump is very fast, thereby has had a strong impact on oil output.
The model utility content
The utility model provides the blade guiding wheel structure of the slow submersible electric pump of a kind of rate of wear to the deficiency of above-mentioned existing technology.
The utility model is realized through following technological scheme:
A kind of blade guiding wheel structure of submersible electric pump; Comprise an impeller and a guide wheel, be provided with an oil duct and a plurality of blade on impeller and the guide wheel, impeller cooperatively interacts with guide wheel and is connected; It is characterized in that it is provided with a plurality of pressure compensation openings with the end face that contacts of guide wheel said impeller.
The further setting of the utility model is: said impeller is provided with first mounting groove and second mounting groove; First mounting groove and second mounting groove are positioned at the joint of impeller and guide wheel; First anti-wear gasket is installed in first mounting groove, second anti-wear gasket is installed in second mounting groove.
The further setting of the utility model is: the center of said impeller is provided with an axle sleeve, can be provided with a locating slot on the said axle sleeve.
The further setting of the utility model is: the surface of said impeller and guide wheel is provided with a plurality of steps.
The beneficial effect of the utility model is:
Impeller in the said blade guiding wheel structure of the utility model is through being provided with pressure compensation opening at it with contacting of guide wheel on the end face; Make the pressure on this contact end face equate with the pressure of wheel bottom; Thereby reduced the frictional force between impeller and the guide wheel, made impeller operation more flexible, the rate of wear of impeller and guide wheel is slack-off; Prolong the working life of submersible electric pump, increased oil output.
