潜油电泵是油田机械采油重要装备之一.其结构细而长,对温度、压力、密封、绝缘等都有较高的要求,制造难度较大.机组工作方式是地面电源通过变压器、电器控制柜后经电缆传输给深入井下的潜油电机,电机带动多级离心泵,将地层深处的石油提升到地面.机组不但要受到高温、高压、酸碱的腐蚀,而且要受到气、水、油的浸泡和砂石、矿物的磨损,一般使用寿命半年至一年.目前只有美国、苏联和中国才能生产这种泵.我国潜油电泵的研制和生产是近几年才开始的.生产厂家有天津市电机总厂、沈阳市电
Submersible electric pump is one of the important equipment for oilfield mechanical oil recovery. Its structure is small and long, and it has high requirements for temperature, pressure, sealing, insulation, etc. It is more difficult to manufacture. The working mode of the unit is the ground power through the transformer, electrical appliances. The control cabinet is then cabled to the submersible motor in the subterranean well, and the motor drives a multi-stage centrifugal pump to lift the oil deep in the formation to the ground. The unit is exposed not only to high temperature, high pressure, acid and alkali corrosion, but also to gas and water. Soaking in oil, sand, and minerals wear, the general service life of six months to one year. Currently only the United States, the Soviet Union and China can produce this kind of pump. The development and production of electric submersible pumps in our country began in recent years. Manufacturers include Tianjin Electric Factory and Shenyang Electric
