试验设备说明 压缩机（1）是喷油回转螺杆型。含油压缩空气通过一个压力控制器（2）被引导到试验过滤器（3）.差压计（4）是用来在记录读数以前建立起操作平衡,压力计（5）记录管线压力。排出空气温度由（6）测量。除去空气所带杂质之外,可能还有管壁液流,因而安装一个管壁液流分离器（7）。正常时空气流动直接经过阀门（8a、8b）和取样盘夹持器 （11）,空气流量由流量控制器（12） 控制, Test Equipment Description Compressor (1) is injection rotary screw type. Oily compressed air is directed to the test filter (3) via a pressure controller (2), which is used to establish operational balance prior to recording readings and pressure gauge (5) to record line pressure. Exhaust air temperature is measured by (6). In addition to the air-borne impurities, there may be a wall flow, thus installing a wall flow separator (7). Normal air flow passes directly through the valve (8a, 8b) and the sampling disc holder (11) and the air flow is controlled by the flow controller (12)
