Abstract
The utility model relates to a hydraulic long stroke energy-saving oil-pumping machine used for the oil exploitation of an oil field. An offset type pulley structure is adopted by a work system, the stroke of an oil cylinder is short, and a long stroke is raised. The stroke length of an integral machine is 3 times of the stroke of the oil cylinder, and the manufacture of an oil pumping machine whose stroke is more than 10 m is easily realized. The hydraulic long stroke energy-saving oil-pumping machine used for the oil exploitation of an oil field is not only suitable for conventional oil exploitation, but also especially suitable for the exploitation of thick oil. A hydraulic transmission system is designed into a structure which can recover and store energy, and energy can be saved more than 70%. Well frames are connected in a hinged mode, the well frames can be folded, and the well frames are convenient to be installed and transported. The hydraulic long stroke energy-saving oil-pumping machine used for the oil exploitation of an oil field has high efficiency and small volume. Compared with a walking beam type oil pumping machine with the same parameter, the hydraulic long stroke energy-saving oil-pumping machine used for the oil exploitation of an oil field can save manufacture steel materials 75%.
