【摘要】：螺杆泵是一种容积式泵，现已被广泛应用于石油、化工、造船、交通运输等行业。随着对螺杆泵需求的增加，实际应用中对其运行效率和可靠性要求越来越高。螺杆泵的性能测试是辨别产品优劣、保证系统性能和促进产品升级的重要手段。 本课题是基于PLC的螺杆泵试验台测试系统的研究。根据螺杆泵试验方法GB/T10886-2002和JB/T8091-1998标准，制定测试方案。其性能测试中需检测的主要参数为泵的进、出口压力、流量、转速、电压、电流和功率等参数。测试系统设计过程综合运用了电气控制技术、PLC技术和数据库技术，设计了基于西门子S7-300PLC的数据采集系统，主要实现螺杆泵性能参数的采集和检测功能；运用STEP7BasisV5.3和WinCC V6.0中文版软件开发了测试系统的上位操作软件，使采集到的试验数据能在计算机上实时显示并生成试验报表和曲线，实现了计算机对试验过程的控制和测试系统的自动化；同时测试系统还建立基于组态软件WinCC的后台关系型数据库SQL Server2000，能够高效管理系统的设备信息和试验数据，提供数据查询和共享功能，保证系统访问的有效性和安全性。 设计的试验台测试系统实现了螺杆泵性能参数检测的预期目标。将PLC、数据库等技术运用于本测试系统，保证了测试的实时性，，提高了测试精度，实现了测试过程的远程监控。
[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.
