真空发生器关键性能检测台设计与实验

The Design and Experiment of the Vacuum Ejector Key Performance Detection Platform

该文通过对真空发生器工作原理和主要性能参数的分析,设计组装了检测真空发生器主要性能参数检测台,使用精密传感器数据采集系统进行采集,通过控制模块在电脑上能准确的读取显示,并绘制出真空发生器的排气特性和真空度—吸入流量特性曲线,更好地为产品性能的提升提供科学合理的检测数据。

In this paper, by analyzing the working principle of the vacuum ejector and its major performance parameters, the detection plat- form using for testing the major performance parameters of the vacuum ejector was designed and assembled. The data was collected by us- ing the precision sensor data acquisition system and can be read and displayed accurately on the computer through the control module. Then, the curves of the exhaust characteristics of the vacuum ejector and the variation between the vacuum degree and suction flow were drafted, which can provide the scientific and reasonable testing data better to enhance the product performance.
