【摘要】 针对目前国内普遍使用的长冲程抽油机冲程长度有限、体积大、操作维修不便、造价高等问题,提出了一种结构新颖的长冲程转轮式抽油机。该抽油机采用一种结构巧妙的换向器装置传递运动和动力,冲程长达6～18m,冲次2～6r/min,可有效提高抽油杆管柱和抽油泵寿命。整机结构紧凑,转轮为折叠式,操作维修方便。现已完成可行性论证与结构设计。更多还原

【Abstract】 To cope with the problems of the long stroke pumping units that have been widely used, we bring up with a new kind of long stroke wheel style pumping unit. A well-made commutator is used to transfer movement and power,and the stroke of this pumping unit is up to 6(?)18m. The complete machine has a compact conformation, and it is convenient for operating and maintening.更多还原
