由兰州石油机械研究所、四川德阳石油化工设备厂和新疆石油管理局联合研制试验的机电部部属科研项目,KCJ4-3.6-7HZ、KCJ5-3.6-7HZ两种型号的宽带抽油机,于1989年12月14日在四川省德阳市顺利通过机电部鉴定。宽带抽油机采用柔性宽带和特殊滚筒传动方式,其构思巧妙,结构紧凑,冲程长,可以不停机进行无级调节工作冲程,运行平稳,使用维护方便,并具有明显的节能效果。经过一年多工业性考验证明,整机性能和电气 The Lanzhou Petroleum Machinery Research Institute, Sichuan Deyang Petrochemical Equipment Factory and the Xinjiang Petroleum Administration jointly developed pilot mechanical and electrical research projects, KCJ4-3.6-7HZ, KCJ5-3.6-7HZ two types of broadband pumping unit, in 1989 December 14, Deyang City, Sichuan Province, passed the Ministry of electromechanical appraisal. Broadband pumping unit adopts flexible wide band and special roller drive mode. Its concept is clever, compact structure and long stroke. It can steplessly adjust work stroke without downtime, run steadily, easy to use and maintain, and has obvious energy-saving effect. After more than a year of industrial tests proved that the whole performance and electrical
