                                        簡述氣瓶外測法-稱重法VS浮動量管法

                                        2016-10-28 0

                                        氣瓶水壓試驗機是參考GB/T15385《氣瓶爆破試驗方法》、SO11439《車用天然氣高壓瓶》、GB/T9251-1997《氣瓶水壓試驗方法》等相關標準設計的。氣瓶水壓試驗外測法常用的有稱重法和浮動量管法兩種,今天就來簡單介紹下這兩種測試方法。

                                        氣瓶水壓試驗方法之稱重法: 

                                        稱重法的要點是受試瓶在受壓的情況下膨脹,將水套中的排出水擠出到量杯中,然后通過高精度電子秤來計算受試瓶的全變形值,當受試瓶卸壓后,容器中的水又回到水套中去,其剩余水的質量減去最初水的質量,就可以得到受試瓶的殘余變形值;

                                        氣瓶水壓試驗方法之浮動量管法:

                                        浮動量管法是根據GB/T9251-1997《氣瓶水壓試驗方法》,浮動量管法是外測法的一種,是對受試瓶進行耐壓試驗的同時從受試瓶外側測量其容積殘余變形率。

                                        關于氣瓶外測法的稱重法和浮動量管法今天就暫時介紹到這里,下期我們將來介紹這兩個外測法的利弊。
