Automated stand for laboratory work on the study of pressure regulators in the water supply system based on a three-phase asynchronous electric drive pump and frequency converter

When preparing students of secondary specialized and higher engineering education, theoretical systematized information within the framework of the studied disciplines should be supplemented by practical work on existing equipment. As part of laboratory work in disciplines related to the study of technical means of industrial automation at the Azov-Black Sea Engineering Institute of the Donskoy State Agrarian University, a stand has been developed and manufactured for laboratory work on the study of PI pressure regulators in a water supply system based on a three-phase asynchronous electric drive pump and frequency converter. With the help of the stand, technical means such as pressure sensors with a current loop output, frequency converters for controlling asynchronous electric drives, digital PI regulators in the water supply system are being studied. During the laboratory work, calibration of the measuring circuit, tuning of the frequency converter, and investigation of the dependence of the transient characteristics on the tuning parameters of the PI controller are performed.
