罗茨机出口至压缩机进口之间安全水封设计刍议

Modest Proposal for Design of Safe Water Seal between Outlet of Root's Blower and Inlet of Compressor

例举了罗茨机出口至压缩机进口之间的敞口式套筒安全水封、封闭式套筒安全水封和箱式U形安全水封的结构和特性 ,着重强调了在设计安全水封时应具备憋压泄压和降压时阻止吸负的双重性 ,并就安全水封在工艺路线中的位置及液封管接点位置的确定提出建议。

The structures and characteristics are listed of the open sleeve, closed sleeve and box U-shaped safe water seal, with stress on the necessary duplicity of pressure holdback and decompression and prevention of negative suction during depressurization in the design of safe water seal, and suggestions are offered on the determination of the positions of safe water seal in process route and connecting point of the liquid-seal tube.
