摘　　要：介绍了Φ323 mm 200 MPa全自动钢管水压试验机的设备组成、工艺流程、各部分机械的结构特点及作用等;论述了该设备应用的关键技术。分析认为:Φ323 mm钢管内200 MPa水压的增压、密封和精准的压力检测是设计难点,超高压元件及超高压水路阀控系统设计是设计关键。该试验机采用的超高压增压技术、分步增压技术、超高压水路阀控系统等,保证了设备的良好运行。The equipment composition, process flow and mechanical structure features and functions of a fullautomatic hydrostatic testing machine with 200 MPa for Ф323 mm steel pipes are described and the key technology of the machine is discussed. Analysis shows that the design difficulties are 200 MPa water pressure boosting inside Ф323 mm pipes, sealing and accurate pressure detection and the key points in design are the ultra-high pressure elements and ultra-high pressure water valve control system. The ultra-high pressure boosting technology, step by step pressure boosting technology and ultra-high pressure water valve control system adopted in the machine can ensure the machine in good operation.
