The Designing of a New Style and Energy Saving Beam Pumping Unit Hydraulic Controlling System

Oil extracting efficiency with good energy saving characters has been an imperative problem remained to be solved.A new style beam pumping unit of energy saving hydraulic controlling system was designed.Controlled by PLC,combined hydraulic transmission technique with mechanical orthographic equilibrium,the system can reclaim and reutilize the kinetic energy during its redirection,so the driving power is reduced and the energy saving purpose is reached.The I/O distribution, the diagram of program frame and ladder programming of the system were introduced according to technology procedure.
