摘　　要：宝钢钢管厂3#油井管线水压试验机是一台集机械、电气、液压、传感、自动控制及计算机等技术为一体的现代化设备,在功能上很好地满足了钢管的水压试验要求,但在使用中也出现了一些问题,尤其是平衡缸位移超差问题。本文从水压试验机的工作原理着手,利用PLC-Analyzer pro软件在不同的参数下对平衡缸位移在增压-保压过程中进行实时监测和记录,分析试验数据,得出平衡缸位移与试验压力、增压系统的压力偏置值、平衡系统的压力偏置值有关。The hydrostatic testing machine in BaoSteel tube plant is an state-of-the-art equipment integrated with mechanics, electronics, hydraulics, sensors, auto-control and computers that can meet the demand of tube hydrostatic test. However, problems, particularly the overrun of the balancing cylinder＇s displacement, occurred in practice. The real-time change of the balancing cylinder＇s displacement during the pressurization and depressurization process was monitored and recorded. It was concluded from the analysis of the data that the displacement is relevant to the testing pressure, the pressurization offset and the balancing system pressure offset.
