摘　　要：简述一种全自动钢管管端水压试验机的主要参数、工艺流程、设备组成以及应用的关键技术,介绍该设备的现场使用情况,并提出改进优化方案。实际应用结果表明:该管端水压试验机结构简单,成本低,系统可靠,试压稳定,故障率极低,达到了设计要求。在后续的设计过程中,可适当提高钢管进出模具的速度,以便进一步提高设备生产效率;改进接水装置,使试压介质达到100%循环利用。Briefed in the article are the main aspects of the a full-automatic hydrostatic testing machine for steel tube end,including the major parameters,the process flow,the equipment configuration and the key techniques as applied. Also described are the details about the actual site operation of the testing machine.Proposed are the plan for improvement and optimization of the said machine.The actual operation result shows that this tester is in possession of such advantages as simplified structure,low costs,reliable system,consistent testing pressure,and remarkably low failure rate,having been up to relevant designed requirements.It is proposed that during the subsequent design process,the speed of the steel pipe as running into/out of the dies should be properly increased to further enhance the productivity of the equipment,and the water-collecting device should be modified to ensure 100% circular utilization of the pressure testing medium.
