The invention relates to an intelligent ultra-long
stroke winch oil pumping unit which is composed of an
electric control cabinet, a balance weight
system, a base, a
winch system and a pumping
system.The
electric control cabinet is connected with the balance weight system, the
winch system and the pumping system through cables, the balance weight system is connected with the winch system througha steel
wire rope, and the winch system is connected with the pumping system through a flexible polish rod. The winch system comprises a displacement sensor, a motor, an
electromagnetic brake, a winchsupport, a speed
reducer, an outer-
square cylinder and a roller. Steel
wire rope tension of the balance weight system and flexible polish rod tension of the pumping system are located at the two endsof the axis of the roller and are opposite in direction. The intelligent ultra-long
stroke winch oil pumping unit is used for improving the
stroke of the oil pumping unit, eliminating an included angle generated between the flexible polish rod and a head sheave, prolonging the service life of the flexible polish rod, realizing the balance weight of the ultra-long stroke oil pumping unit, and further saving energy, by adding an intelligent
chip, the pump efficiency, the yield and the annulus liquid level position of an oil jacket can be instantly reflected, and the oil pumping speed is automatically adjusted or oil is intermittently pumped according to liquid supply data. Efficient operation is achieved.
