喷水螺杆压缩机中充氮密封系统的设计

Design of Nitrogen-filled Seal System for Water-cooled Screw Gas Commpressor

介绍了大型喷水螺杆压缩机中充氮密封系统的工作原理。设计中利用密封油收集器和压差气动薄膜调节阀来控制充氮量的大小和压力的大小 。

Using collector-controller of seal oil and pressure-difference pneumatic membrane adjustment valve quantity and pressure of filling Nitrogen was controled in order to decrease wastage of Nitrogen.
