BALANCE CONTROL OF ROCKING MACHINES

An analytical review of the methods of controlling the balance of the rocking machine of the rod deep-pumping installation for oil production (SHРU) is given is presented, which determines its technical condition. A classification of methods for balancing a pumping machine is proposed according to two criteria: the type of mechanical implementation and the method of diagnosing (identifying) the state of balance. Existing methods for controlling balance are analyzed with a special emphasis on wattmeterographic methods, assessing their advantages and disadvantages. Taking into account the intellectualization of the process of mechanized oil production, prospective directions for the development of methods for balancing pumping machines using sensorless control methods for SHPU are considered, in particular the power integration method, the use of intelligent controllers (SSRP), artificial intelligence algorithms and dynamic modeling.
