EL7342查看風(fēng)缸的焊接處和壓縮氣氣管的狀況

這一步驟主要是檢查風(fēng)缸的焊接是否出現(xiàn)裂縫，以及壓縮氣氣管是否有裂痕或沙眼。如果一個焊接點沒接牢，地鐵運行過程中就極可能出現(xiàn)意外停機事故，因此要定期檢測各處的焊接情況。

風(fēng)缸的焊接狀況

壓縮氣氣管位于車廂和底座之間，空間十分狹小，一般很難用肉眼檢測，借助FLIR VS80-KIT2內(nèi)窺鏡探頭伸入檢測部位，就可以看到氣管的全部狀態(tài)，管壁情況一覽無余，再使用放大功能就可以輕松地觀察到氣管是否存在裂縫和沙眼。

判斷避震彈簧和空氣簧是否需要更換

后需要檢測的是地鐵車輛中避震彈簧和轉(zhuǎn)向架的空氣簧是否需要更換或維修。

通過FLIR VS80的大屏主機可以看清轉(zhuǎn)向架空氣簧的橡膠紋路，在以前沒有內(nèi)窺鏡的情況下只能用鏡子來檢查，既費時又費力還看不清，現(xiàn)在有了FLIR VS80高清視頻內(nèi)窺鏡，節(jié)約了檢測時間，大大提高了檢查效率。

檢測轉(zhuǎn)向架的空氣簧內(nèi)壁（該被測物的材質(zhì)是橡膠），需要檢測內(nèi)壁是否有破損和劃痕。

檢測彈簧內(nèi)部，FLIR VS80-KIT2也能應(yīng)對自如，將探頭伸入彈簧縫隙，使用搖桿探頭轉(zhuǎn)向觀測彈簧內(nèi)部的磨損情況和狀態(tài)，以判斷其是否需要更換。

在本次地鐵設(shè)備檢測的整個過程中，FLIR VS80-KIT2內(nèi)窺鏡得到了非常高的評價，其幫助地鐵檢測員大大縮短了檢測時間，提高了工作效率。從探頭分辨率、顯示屏清晰度、放大功能、光照強度等都滿足了客戶的檢測需求，比之前使用的其他檢測工具要更清晰、更便捷！
