[Abstract]:Screw pump is a kind of volumetric pump, which has been widely used in petroleum, chemical, shipbuilding, transportation and other industries. With the increasing demand for screw pump, its operation efficiency and reliability are more and more demanding in practical application. The performance test of screw pump is an important means to distinguish the quality of the product, ensure the system performance and promote the upgrade of the product. This subject is based on PLC screw pump test platform test system research. According to the standard of GB/T10886-2002 and JB/T8091-1998 of screw pump test method, the test plan is established. The main parameters to be tested in the performance test are pump inlet, outlet pressure, flow rate, rotational speed, voltage, current and power. In the design process of the test system, the electric control technology and the database technology are used synthetically, and the data acquisition system based on Siemens S7-300PLC is designed, which mainly realizes the function of collecting and detecting the performance parameters of the screw pump. The upper operating software of the test system is developed by using the Chinese version of STEP7BasisV5.3 and WinCC V6.0. The collected test data can be displayed in real time on the computer and the test reports and curves can be generated. At the same time, the test system also establishes the background relational database SQL Server 2000 based on configuration software WinCC, which can efficiently manage the equipment information and test data of the system. Provide data query and sharing functions to ensure the effectiveness and security of system access. The test system designed has achieved the expected goal of testing the screw pump performance parameters. The technology of PLC and database is applied to the test system, which ensures the real time of the test, improves the precision of the test, and realizes the remote monitoring of the test process.
