(POSSIBILITY OF INCREASING ROTOR SPEED REGULATION RANGE OF AN ELECTRIC SUBMERSIBLE PUMP ROTOR BY MEANS OF DAMPER BUSHINGS)
The paper presents the results of bench tests of bearing bushings used as a part of electric submersible pumps for oil production. The studied bushings differ in their design from standard bushings made of VK6 material and consist of a bushing of variable cross-section and an elastomeric ring (bushing damper).
The bench tests were carried out on the stands in the educational and scientific laboratory of the Department of Machines and Equipment of Oil and Gas Industry of the Gubkin Russian State University of Oil and Gas (National Research University). At the initial stage of researches values of vibration indicators have been measured, then resource tests of bushings dampers as a part of bearing units of mini-section of standard stages of the submersible pump have been carried out, then by means of the special vibration converter the vibration indicators in the upper and lower section of the pump section in places of installation of bearings have been taken.
As vibration values were selected changes of root-mean-square values of vibration velocity in two planes – on axes X and Y – after endurance tests.
The results of the tests presented in the article allow to extend the frequency control range of the rotor of electric submersible pumps through the use of special bushings dampers.
