SJHT套筒接头水压测试机介绍
设备功能、组成及原理：
设备功能
套筒接头水压测试机是连续管道生产线上检测设备，用于连续缠绕管道套筒接头水压测试
设备组成
主要由水压机受力框架、推进装置、注水增压装置、上下套筒接头装置、套筒接头拨出装置、套筒接头密封盘 、液压装置、电控及测试数据显示系统等机构组成 。
工作原理
将要测试水压套筒接头放置在上下套筒接头装置上，使套筒接头中心与套筒接头密封盘中心大约相同，起动液压装置使密封盘压入套筒接头。起动增压泵注水增压到设定压力后，增压泵自动停止。关闭增压管道上阀门保压一定时间。移动密封盘使密封盘从套筒接头内拨出放水。完成套筒接头水压测试工作。
Introduction to Sleeve Hydro-testing Machine
Equipment function, composition and working principle:
Function--
As an auxiliary equipment in the continuous winding production line, Sleeve Hydro-testing Machine is designed for the hydro-static testing of sleeves.
Composition--
It mainly consists of machine stress frame, propulsion device, filing and forcing device, sleeve loading and unloading device , sleeve allocating device, sleeve fixed sealing plate, sleeve movable sealing plate, hydraulic device, electrical and testing data display system.
Working principle--
Lay the sleeve for hydro-testing onto the sleeve loading and unloading device, aiming the sleeve center at those of sealing plates. Then, start the hydraulic device to push sealing plates into sleeve. Start the forcing pump which will automatically stop after reaching the setting pressure. After that, close the valve of the forcing pipeline and keep pressure for a certain period. Finally, move back the movable sealing plate to make pipe end extracted and drain, thereby finishing the sleeve hydro-testing.
