| Abstract: | LZCB long-stroke chain pumping unit is developed to solve the qroblems of the conventional long-stroke pumping unit, such as high fault rate of its reverse device and complicated configuration of balance mechanism. This new pumping unit adopts a symmetrically-arranged reverse device with slide bearing to solve effectively the problem of side bending moment, and uses a widened bidirectional guide wheel with slide bearing to make the guide mechanism more reliable. In addition, a gravity balance system connected by 2 guide chain wheels is designed to realize precise balance. The unit has the characteristics of smooth operation and simple reverse and convenient balance adjustment. |
