流量调节阀性能检测系统设计
A design of detecting system for flow regulator
摘要
Abstract
For the requirements of test instruction for flow regulator, a set of automatic detection system based on the LabVIEW was designed. It was combined with high-precision data acquisition, motor control and serial communication, etc. It realized flow regulator adjusting with range of upper and lower limit position setting and work-flow characteristic curve of verification, the stability and repeatability of actuator, etc. In this paper, the hardware composition composed by pressure sensor, flow sensor, PLC, PWM generator, DAQ card, industrial control computer and linear power supply, etc. The software implementation adopts distributed test mode by PC and PLC, which the PC was responsible for data acquisition and analysis and the PLC responsible for serial communication. Through test results, the max standard deviations of flow and displacement stability were 0. 04 kg/h and 4 mm respectively. And measuring capability indexes, include CG and Cgk , were great than or equal to 1. 33. So this system meets the equipment acceptance requirements.关键词
