摘　　要：对新型变频节能液压抽油机进行了方案分析和理论设计。该机采用具有特殊结构的液压缸,将变频容积调速技术与闭式液压回路以及蓄能器回路相结合,具有体积小、长冲程、大载荷、降低装机功率和能耗、自适应性好和适应范围广等特点。A new energy -saving hydraulic pumping unit was presented. It uses a special construct hydraulic cylinder and combines variable frequency hydraulic technology with closed oil circuit system and accumulator oil circuit. It features small volume, long stroke, large load, reduced power and low energy consumption, good self - adaption and wide field of application.
