<晴风村n style="box-sizing: border-box; font-size: 16px; font-family: Calibri;">2.<晴风村n style="box-sizing: border-box; font-size: 16px;">检查衬氟磁力泵叶轮中心轴是否偏移，用手转动叶轮看是否顺畅，转动的同时查看双面的间隙是否同宽。如果有偏移，用螺栓刀松开隔离套后部<晴风村n style="box-sizing: border-box; font-size: 16px; font-family: Calibri;">3<晴风村n style="box-sizing: border-box; font-size: 16px;">个螺丝重新校准中心轴，直至校准旋紧，如果损坏应立即更换。
<晴风村n style="box-sizing: border-box; font-size: 16px; font-family: Calibri;">3.<晴风村n style="box-sizing: border-box; font-size: 16px;">取出叶轮用手轻触叶轮轴是否松动，隔离套后部螺丝是否松动，是否锈蚀。如果松动在校准中心轴的同时旋紧后部螺丝。
