由中国石化总公司北京设计院设计、乐清自动化仪表九厂负责控制部分的制造、乐清自动化仪表三厂负责机械部分的制造及整机的总成的新型小鹤管,在乐清自动化三厂空载调试成功。 该鹤管的特点:①旋转接头是专门设计的,精密灵活,在技术上有突破性的进展;②采用密闭的浸没装车,减少油气挥发;③设有气相管,叮将装油时从油罐(通过密闭盖的开口)排出的空气和油气的混台物引离操作现场,视具体条件,或者放空,或者回收,或者引至加热炉作燃
Design by the China Petrochemical Corporation Beijing Institute of Design, Yueqing Automation Instrumentation nine plants responsible for the control part of the manufacturing, Yueqing Automation Instrumentation Factory responsible for the mechanical part of the manufacture and assembly of the new small crane, Automation Factory in Yueqing empty Debugging success. The characteristics of the crane tube: ① rotary joint is specially designed, precision and flexible, a breakthrough in technology progress; ② the use of a closed immersion loading to reduce oil and gas volatilization; ③ with a gas tube, The mixture of air and oil and gas discharged from the tank (through the opening of the closure cap) is removed from the operation site, either under specific conditions, either vented or recycled, or directed to the furnace for ignition
