The author: Time:2019/8/22

       氣動切斷閥的檢修注意事項:
       1、在解體單作用氣缸時,應(yīng)注意氣缸彈簧有一-定的預(yù)緊力,應(yīng)緩慢同步拆出活塞環(huán)蓋體,防止被傷到;
       2、左右活塞環(huán)的密封環(huán)前端分別有個白色有缺口的塑料環(huán),它為導(dǎo)向環(huán),正常情況下就有缺口;
       3、在更換密封環(huán)過程中必須保證工作中操作者和所使用工器具潔凈,并加一定量的潤滑脂。
       上述是氣動切斷閥廠家關(guān)于檢修時的注意事項,希望能對你有所幫助,如果你有產(chǎn)品的需要,可電話與我廠家咨詢。
