摘要
针对传统的离心泵性能测试系统存在着测试手段落后,操作费时,测量速度慢,精度低等问题,自行研制了一套基于RS485的离心泵性能自动测试系统。基于该系统的离心泵性能实验台实现了全自动化的性能试验与汽蚀性能试验,包括阀门与真空泵的自动控制、实时数据采集、数据处理和保存、曲线绘制以及自动生成试验报告等。试验结果表明:该系统很好地弥补了传统测试系统存在的不足,具有自动化程度高,测量精度高,测量速度快的特点。
In the traditional measuring bench of centrifugal pump the means of measuring was lagged, the speed was slow, and the accuracy was insuffient. To solve the above problems, an auto-measuring system based on RS485 Bus was developed. The system could realize the performance and cavity tests which in- clude the auto-control of valve and vacuum pump, real-time data acquisition, data processing and saving, plotting and getting the report of testing. The result of experiment show that the system make up for the fault in the traditional measuring system, and has features that the degree of automatization is high, the accuracy is suffient and measuring speed is quick.
