儀表軸尖損壞的主要原因

發(fā)布日期:2022-07-14 點(diǎn)擊率:78

  (1)在頻繁使用中,軸尖磨損變鈍;

  (2)由于儀表受到劇烈的機(jī)械震動,而導(dǎo)致鈾尖尖端裂損, ;

  (3)軸尖與軸承間隙調(diào)的不當(dāng),軸承螺絲旋得過緊,使軸尖壓彎損壞;

  (4)儀表長期不按規(guī)定方向(垂直或水平)使用,出現(xiàn)軸尖一邊磨損;

  (5)由于軸承內(nèi)有裂紋或臟物,也會導(dǎo)致軸尖磨損;

  (6)由于鈾尖與軸承的曲率半徑之比值不當(dāng),鈾尖的曲率半徑磨得過小,而軸承曲率半徑又較大,致使納尖與軸承間的靜壓力增加,使鈾尖磨損或抽承裂損;

  (7)使用地點(diǎn)濕度較高,會造成軸尖生銹;

  (8)軸尖由于沾有酸性物質(zhì)或用手觸模,也會造成軸尖銹蝕。
