| The paper presents and justifies the approach to decreasing the vibration level of downhole electric centrifugal pumps (ECP) from their disbalanced rotating parts as the main factor determining the vibration activity of the ECP. The approach is based on the principle of selective assembly (that consists in determining the sequence of the working wheels arrangement on the shaft axis, closest to the optimum one on the structure vibration level) |
