Testing methods for steam jet air ejectors 射汽抽气器的试验方法
For hogging purpose two 100 % vacuum ejectors ( one work one standby with hogging ejector ) are provided 基于建立真空的目的,我们提供两台100 %两级射汽抽气器(带启动抽气器) 。
Before steam admission , valve on vacuum hogging extraction line ( the valve is befor hogging pipe of the two stage steam jet ejector ) should be closed ( see also two stages steam jet ejector installation and operation instruction ) 在蒸汽进入之前,抽真空启动管道上的阀门(启动抽汽器前的阀门)应该关闭(请参见相应的两级射汽抽气器安装使用说明书) 。
