                                        螺旋管水壓試驗機的工作原理

                                        2012-02-23 0

                                        螺旋管在進行水利方面的應用的時候要進行水壓試驗,以保證螺旋管的質量,通常在試驗的時候都是用試驗機來進行測試。那么水壓測試機的工作原理是什么呢?下面大家就來了解一下吧!

                                        螺旋管水壓試驗機的工作原理:

                                        螺旋管水壓試驗機在進行試壓時,首先通過端部密封裝置對受試鋼管兩端進行密封并注入低壓水,在注水過程中通過排氣閥排出管內空氣,在低壓水充滿后,通過增壓裝置向管內注入高壓水進行增壓直至達到規定試驗壓力。在達到規定試驗壓力后按規定時間保壓,若螺旋管在試壓中無泄漏、變形等現象,則進行卸壓。然后打開端部密封裝置,排出低壓水,將受試螺旋管送到檢查臺進行目視檢查有無可疑滲透。按標準要求對試壓過程的壓力變化曲線采用自動記錄裝置記錄。
