“…Based on the hardware platform built in this system for debugging, the values of dead zone and upper and lower limits are set so as to reduce the over-regulation and oscillation of the controller and ensure the stability and safety of the system [21]. In order to improve the accuracy of the control as well as the response time in the case of small flow rate, the deviation value is calculated using the square of the flow [22]. Which set 𝐾𝐾 𝑝𝑝 = 0.02, 𝐾𝐾 𝐼𝐼 = 0.1 and verified through the test, it can be faster and more stable regulation of the flow rate to reach the set point [23][24][25][26].…”

With the development of automation technology, it gradually replaces manual labor in various fields. Pumps are widely used in various production processes in the industrial field. To enhance the automation level of the pump production and testing process will significantly reduce production costs. This paper aims to design and realize a set of fully automatic, high-precision pump performance testing system. The fully automated operation of the performance test is designed according to the flow rate automatic sampling method, to achieve the accurate measurement of the pump operating conditions. Utilizing the PID algorithm, the valve is automatically adjusted through PLC control to realize the accurate positioning of the flow measurement point. With the help of the software program to carry out the calculation and analysis of test data, to achieve the visualization of the test process of the whole performance test data management. At the same time, SQL Server database is used to realize rapid query and management of test data. After the test verification, the system realizes the full-automatic measurement of the pump performance curve, and the measurement accuracy conforms to the standard of ISO 9906:2012.
