Modern electrically driven vane pumps (EVP) are an important element of oil and gas production, ensuring efficient oil production in various operational conditions. Digitalization of this type of equipment operation is based, among other things, on the analysis of the level of ELP vibration characteristics, which are a critical indicator showing a change of the state of the reservoir – well – pumping unit system. Vibration characteristics increase, for example, the mean square value (MSV) of vibration velocity, indicates a change of equipment operational mode and allows assessing the impact of these changes on the system reliability. The authors of the article present the results of bench tests of vane pump sections with innovative radial bearings. The bushings of the above-mentioned bearings differ from standard bushings made of hard alloy by their design and the principle of receiving loads from the rotor of the pumping section. Bench tests were carried out at the stands in the educational-scientific laboratory of the Department of Machinery and Equipment of the Oil and Gas Industry of National University of Oil and Gas "Gubkin University". The tests include determination of vibration values at different rotational speeds of the pump sections rotor before and after wearing tests. The results of hydrodynamic and vibration tests before and after resource tests are presented. Vibration parameters are measured in the upper and lower sections of the pump section at the bearing sites using a special vibration transducer. The results presented in the article have proved the possibility of using innovative radial bearings in the pumping sections of the EVP when operating under difficult operational conditions and in a wide range of rotor speeds of electric vane pumps.
