大直径超高压旋转水射流装置的研制及工程应用

摘要

Through study of the water jet dynamical parameters and the ultra-high pressure rotary seal structure of the device those operating diameter not less than 300mm and operating pressure not less than lOOMPa, the aperture of nozzle tip, target distance and rotary speed are determined. And the rotary seal structure of lOOMPa and 250MPa pressure rating are designed. It is proved that the device based on plane cleaner type are safe and had high efficiency during application.%针对作业直径不小于300mm、工作压力不小于100MPa的旋转水射流装置从主要水射流动参数确定和超高压旋转密封结构人手进行研究,确定了喷嘴孔径、射流靶距、转速等典型的水射流动参数,并完成了100MPa和250MPa两个压力等级的旋转密封组件的结构设计,研制出以平面清洗器为基本形式的水射流装置,并在实际工程应用中体现出高效和安全的特性.
