Tower type mechanical reversing (belt) vertical pumping unit is a vertical pumping unit with chain closed-loop drive and belt traction.
This series of vertical pumping unit has the advantages of long stroke, adjustable stroke, simple operation, convenient transportation, stable operation, etc. compared with the beam pumping unit with the same rated load, it needs a smaller reduction box torque, a smaller motor power, and an obvious energy saving effect. It is especially suitable for the exploitation of deep well, ultra deep well and heavy oil reservoir. During the workover, large hoisting equipment is not needed, and personnel can complete the work without climbing, which makes the work safe, reliable and easy.
