使用注意編輯1、儀表必須垂直:安裝時應(yīng)使用17mm扳手旋緊,壓力表(圖5)不應(yīng)強(qiáng)扭表殼;運(yùn)輸時應(yīng)避免碰撞;2、儀表使用宜在周圍環(huán)境溫度為-25~55℃;3、使用工作環(huán)境振動頻率<25HZ,振幅不大于1mm;4、使用中因環(huán)境溫度過高。 電動式錐形揚(yáng)聲器即過去我們常說成紙盆揚(yáng)聲器,盡管2014年振膜仍以紙盆為主,但同時出現(xiàn)了許多高分子材料振膜、金屬振膜,用錐形揚(yáng)聲器稱呼就名符其實(shí)了。錐形紙盆揚(yáng)聲器大體由磁回路系統(tǒng)(永磁體、芯柱、導(dǎo)磁板)、振動系統(tǒng)(紙盆、音圈)和支撐輔助系統(tǒng)(定心支片、盆架、墊邊)等三大部分構(gòu)成。

如果是由于基座被磨出深槽而將支架軋住,可將支座磨出的深槽用環(huán)氧填平,器又可以工作。環(huán)氧:75%環(huán)氧、10%問苯二胺和15%酐。③鐵芯磨損表面變形是器普遍存在的問題,鐵芯表面經(jīng)過長期碰撞后,沿疊片厚度方向向外擴(kuò)張,并且表面碰的高低不平,造成鐵芯有噪聲,還會造成因剩磁較大而粘住銜鐵。
