Abstract
The utility model relates to a novel long stroke energy-saving pumping unit. The novel long stroke energy-saving pumping unit comprises a main frame, a power mechanism installed on the main frame, a guide mechanism, a balance weight mechanism and a control cabinet. The control cabinet is in circuit connection with the power mechanism. The power mechanism is connected with a terminal load of the pumping unit through a rubber traction belt. The power mechanism and the guide mechanism are installed on an upper platform of the main frame, and the balance weight mechanism is installed inside the main frame. The other end of a guide wheel bracket is hinged on one side of the upper platform. The height of center of the guide wheel is lower than that of a drive wheel. According to the long stroke energy-saving pumping unit provided by the utility model, the balance weight mechanism is installed inside the main frame so that the balance weight mechanism reciprocates up and down stably with smaller reversing impact. The balance weight rubber traction belt is connected with a balance weight box through a rear belt roller so as to reduce the friction between a balance weight pulley and a balance weight slide rail so as to reduce the noise. In addition, the slide rail can be assembled before suspension so that the slide rail is more convenient to adjust. The guide wheel inclines backward and overturns along with the guide wheel bracket so that the well is convenient to repair and maintain with low cost.
