Abstract:The article considers the designs of electrohydraulic drives (EHD) of sucker rod well pump units (SRPU), the factors re-straining the introduction and wide spread of promising SRPU at oilfields being revealed. The search for technical solu-tions allowing to eliminate the revealed problems is carried out. The design features of the EHD SRPU are being ana-lyzed. It is shown that the most widespread in the Russian oilfields is the EHD SRPU with electrodynamic balancing. The statistical information on emergency fa… Show more
