Abstract

Abstract The purpose of the study is to increase the service life of coupling joints of centrifugal pumping units by designing a modernized coupling joint. During the operation of centrifugal units, there is a problem associated with a short service life of the couplings due to the imbalance of the half couplings, improper balancing of the rotor, etc. The authors conducted an objective and comprehensive analysis of the flexible coupling operation. Based on the results of the study of the existing construction, the coupling joint was modernized using the example of the pin flexible coupling for a centrifugal pump 200D90. The flexible coupling construction, which has no analogues in Russia, has been created. Due to the proposed upgraded construction, the coupling provides increased service life and more reliable operability in service.
