Abstract
The utility model provides a blade guide wheel of an electric submersible pump, comprising an impeller and a guide wheel, wherein each one of the impeller and the guide wheel is provided with an oil channel and a plurality of blades; the impeller is connected with the guide wheel in a matched manner. The blade guide wheel is characterized in that the impeller is provided with a first mounting groove and a second mounting groove; the first mounting groove and the second mounting groove are mounted at the connecting part of the impeller and the guide wheel; the first mounting groove is internally provided with a first abrasion-reducing cushion; and the second mounting groove is internally provided with a second abrasion-reducing cushion. According to the blade guide wheel of the electric submersible pump, the two mounting grooves are arranged at the connecting positions of the impeller and the guide wheel and the abrasion-reducing cushions are arranged in the mounting grooves, so that the abrasion generated in an operation process of the impeller and the guide wheel is further reduced, the abrasion speed of the impeller and the guide wheel is slowed, 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 submersible electric pump blade guiding wheel.
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 existing submersible electric pump blade guiding wheel rate of wear is very fast, thereby has had a strong impact on oil output.
The model utility content
The utility model provides a kind of rate of wear slow submersible electric pump blade guiding wheel to the deficiency of above-mentioned existing technology.
The utility model is realized through following technological scheme:
A kind of submersible electric pump blade guiding wheel comprises an impeller and a guide wheel, is 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 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:
The described submersible electric pump blade guiding wheel of the utility model is provided with two mounting grooves at the link position of impeller and guide wheel, and wear-resistant pad is installed in mounting groove; And then significantly reduced the wearing and tearing that impeller and guide wheel produce in running, and make that the rate of wear of impeller and guide wheel is slack-off, prolonged the working life of submersible electric pump, increased oil output.

Fig. 2 is the plan view of impeller;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the structure split figure of guide wheel.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-4, the utility model provides a kind of submersible electric pump blade guiding wheel, comprises an impeller 1 and a guide wheel 2; Be provided with an oil duct and a plurality of blade 3 on impeller 1 and the guide wheel 2; Impeller 1 cooperatively interacts with guide wheel 2 and is connected, and said impeller 1 is provided with the joint that first mounting groove 4 and second mounting groove, 5, the first mounting grooves 4 and second mounting groove 5 are positioned at impeller 1 and guide wheel 2; Be equipped with in first mounting groove 4 in first anti-wear gasket, 6, the second mounting grooves 5 second anti-wear gasket 7 is installed.
Preferably, for the ease of being connected of impeller 1 and pump shaft, the center of said impeller is provided with an axle sleeve 8, can be provided with a locating slot 9 on the said axle sleeve.
Preferably, in order to reduce the suffered pressure of impeller 1 and guide wheel 2, the surface of said impeller 1 and guide wheel 2 is provided with a plurality of decompression steps.
The above is the preferred embodiment of the utility model, and all equivalent variations of being done according to the utility model claim all should belong to the protection domain of the utility model.
