    柜式离心风机时会发现一些问题,比如风机轴承温度短时间快速上升,这会对风机的使用造成很大的影响,下面小编给大家详细讲解轴承短时升温过高的原因和如何解决这个故障的方法 When we use Ludao Fan Cabinet Centrifugal Fans, we will find some problems, such as the rapid rise of the bearing temperature of the fan for a short time, which will have a great impact on the use of the fan. High causes and how to resolve this failure

    Reasons for the excessively high temperature of Ludao fan fans:

    进风口或者叶轮与进风口产生摩擦,阻力产生导致轴承运转过程中受力加大,导致故障产生; 1. The air inlet or impeller has friction with the air inlet, and the resistance will cause the bearing to be stressed during the operation, which will cause the failure;

    轴承箱与滚动轴承外圈产生摩擦,内圈相对主轴转动摩擦、轴弯曲、损坏等都会造成轴承短时间升温; 2. Friction between the bearing box and the outer ring of the rolling bearing, the friction of rotation of the inner ring relative to the main shaft, shaft bending, damage, etc. will cause the bearing to heat up for a short time;

    轴承的冷却液过少或者中断; 3. The coolant of the bearing is too little or interrupted;

    滚动轴承和轴安装不恰当,一前一后两个轴承不在一个平面; 4. The rolling bearings and shafts are improperly installed, and the two bearings are not on the same plane.

    润滑油质量不好,或者润滑油受到污垢、沙粒、灰尘等杂质污染; 5. The quality of the lubricant is not good, or the lubricant is polluted by impurities such as dirt, sand, dust, etc .;

    In order to solve these small faults and cause the normal use of the fan, the following points need to be done on the fan bearings:

    控制轴承润滑油的使用时间,一般半年就要更换一次,第一次使用 200 小时后就要更换润滑油,润滑油要定期检查看看有没有变质; 1. Control the use time of bearing lubricants. Generally, the lubricants must be replaced once every six months , and the lubricants must be replaced after 200 hours of first use . The lubricants must be checked regularly to see if they have deteriorated.

    观察轴承润滑油供应是否正常,如果出现漏油现象,要把螺栓拧紧,如果还没解决问题则需更换密封填料; 2. Observe whether the bearing lubricating oil supply is normal. If oil leakage occurs, tighten the bolts. If the problem has not been solved, replace the sealing packing;

    The above are the reasons and solutions for the short-term temperature rise of Ludaofeng centrifugal fan bearings.
