| Abstract: | A new type of energy-saving and long-stroke pumping unit is designed. The unique eccentric gravity-equipoise mechanism and hook-reverse mechanism are adopted in this kind of pumping unit to simplify its structure, average the forces applied to it, make it run steadily and improve its reliability. Moreover, this kind of pumping unit can be started in the condition of zero-load and run in the condition of full-balance. |
