电潜泵自1926年问世以来,已经经历了三个阶段。八十年代以来,为了提高泵效和机组的免修期,在产品的设计结构、材料选用和制造工艺上的改进与更新不断地有所创新。特别是由于电子工业的飞速发展,使电潜泵设备及其配套技术又有了更大的发展。 Electric submersible pump since its introduction in 1926, has gone through three stages. Since the 1980s, in order to improve the pumping efficiency and the unit’s maintenance-free period, innovations and innovations in product design structure, material selection and manufacturing process have been continuously made. In particular, due to the rapid development of the electronics industry, there has been a further development of ESP equipment and its supporting technologies.
