Summary:In view of the current situation that adjustable electro-hydraulic actuators for pipeline depend on import, effortshave been made to the localization of adjustable electro-hydraulic actuator to guarantee the safety of national energy, toimprove the benefits of pipeline industry and to promote the development of national industry in China. The technical statusat home and abroad was sorted out, and based on the characteristics of pipeline industry, the adjustable electro-hydraulicactuator with dual power system was developed with the unique design technology of hydraulic loop, double closed loopPID control technology and non-contact high-precision measuring technology of magnetostrictive displacement, of whichthe industrial demonstration application was carried out in the oil stations such as Lishu Station and Linyuan Station ofDaqing-Tileling IV Pipeline. The results of factory test, field industrial test and application indicate that only little gap existsbetween the domestic and imported adjustable electro-h
