亨达电机为您解析纺织电机损耗较大的原因
2018-03-07 13:17:00
source:admin
机械损耗是影响纺织电机效率的五大损耗之一,亨达电机技术人员现将影响纺织电机机械耗较大的原因给大家做一个总结和分享:
1.轴承或轴承装配质量不好,此时轴承将严重发热;
2.外风扇用错(如2极纺织电机使用了4极的风扇)或扇叶角度有误
3.机座和两端盖轴承室不同轴度较大
4.轴承室直径小于标准值,使轴承外圈受压变形,造成轴承摩擦损耗较大
5.轴承室内加入的润滑脂过多或油脂质量不好
6.定转子相擦
7.转子轴向尺寸不正确,造成两端顶死,使转动不灵活
8.油封或甩水环等部件安装不正或变形,产生较大的摩擦力
以上是影响纺织电机机械损耗较大的几种因素,其中第五种因素往往易被大家忽视。纺织电机在使用一段时间后,需要加润滑脂,但不是越多越好,润滑脂过多反而会增加纺织电机的机械损耗,使轴承发热,影响轴承的使用寿命。
