Offset Wheel Beam Pumping Unit
This kind of pumping unit is developed form the out-phased beam pumping unit. An offset wheel is placed at the back of the walking beam and thus a six-bar mechanism is formed which is centered at the offset wheel. The torque of gear reducer can be adjusted gently be changing the variation principle of the polished rod load, the length of the equivalent rear arm and the offset angle of the crank. This product can be applied to oil wells with different kinds of well conditions.
Standard: API SPEC 11E standard.
