                                        壓力試驗中需要注意的事項

                                        2016-03-30 0

                                        壓力試驗中需要注意的事項:

                                        1,安裝壓力測量儀表時,應注意排凈壓力測量儀表及其接管內的空氣。

                                        2,在升壓過程中若發現升壓速度明顯增快或減慢的現象時,應立即停止水壓泵,尋求升壓速度異常的原因并予以處置。

                                        3,壓力測量儀表的示值不為“零”時,嚴禁拆卸承壓管道上的一切承壓件和拆裝受試工件,嚴禁旋轉承壓管道的街頭。

                                        4,泄壓時必須使壓力緩慢下降。

                                        5,若發現試前準備或試驗過程中某一環節有失誤,而可能影響試驗結果的正確性時,則該次試驗無效。
