摘　　要：压力容器试压工作站在石油化工压力容器的制造中起着至关重要的作用。由于采用了PLC-变频控制技术,在试压工作中操作尤为方便,自动化程度高、效率高、节能效果好,打破了试压工作的传统方式,解决了试压数量、环境气温、水源状况对试压的影响。阐述了压力容器试压工作站的工作原理、电气控制设计思路及PLC系统的选型,并介绍了PLC的安装及接线方法。Pressure vessel test stations play an important role in the manufacture of pressure vessels in petrochemical industry. The application of PLC-Programmable Logic Controller has made the handling of pressure tests more convenient,with higher degree of automation,higher efficiency and better energy saving. It breaks traditional ways of pressure testing,avoiding in flunces of factors like testing amount,ambient air temperature and water conditions on the testing. In the paper,work principle,design thought of electric control and model selection of PLC system were described and PLC installation and wiring methods were introduced.
