                                                                                                                                                                                            發布時間:2022-03-23    點擊次數:

                                                                                                                                                                                            首先我們要知道電子拉力試驗機為什么會出現數據不準確的問題,其原因也是多方面的,電子拉力試驗是要工件工作在屈服點的,在這樣的環境下很容易工件出現塑性變形,或是斷裂,從而會造成電子試驗機數據不準確。

                                                                                                                                                                                            電子拉力試驗機為什么會出現數據不準確

                                                                                                                                                                                            1、卡盤可能出現松動,一般都是突然斷裂造成的。

                                                                                                                                                                                            2、電路出現問題,主要是塑性變形造成的,因為塑性變形可能會給電路造成一些過載,造成電容被擊穿,影響試驗數據。

                                                                                                                                                                                            那么相對應的解決檢修的方法分為:測試修,小修,大修。每一個星期做一次測試修,測試修主要是進行測試,測試方法為:測試一下以前的一個工件,除去上次試驗測試誤差,然后看誤差是多少,進行各個容易松的地方,進行鎖緊,然后測試盡可能把誤差降到小。

                                                                                                                                                                                            小修:也就保養,就是對設備各個地方進行檢測和測試,清理各個地方異物,測量為的是下次大修做準備。大修:是根據近觀察,和小修測量進行磨損比較大的零件換或者修復。
