Analysis on the heating problem of centrifuge motor bearing

There are several reasons for the heating of the centrifuge motor bearing, which should be carefully analyzed in detail.

First, it may be due to overload or overload, there may be problems such as cooling fans, or heat generated by mechanical friction, but the main problem is whether the bearing is authentic, and some users buy low prices for low prices. Bearing, resulting in bearing heating, hot, so that the bearing burns and so on. Therefore, it is first emphasized to purchase authentic (imported) bearings. The bearings used in the centrifuge series are all imported SKF bearings.

Second, pay attention to maintaining mechanical lubrication and use high-temperature lithium-based grease. The quality of lithium-based grease is also another main reason for bearing heating. In addition, you should check with your detailed conditions. If the mechanical friction will be accompanied by noise, and the mechanical parts will be obviously worn, if the bearing is loose, it should be a problem with the bearing, and the bearing needs to be replaced. It is recommended to purchase authentic imported bearings. The centrifuge is a high-speed equipment, and high-speed rotation requires the use of good bearings. Authentic bearings can ensure the long-term normal operation of the centrifuge, and the service life can be as long as more than 10 years.

Thirdly, whether the concentricity of the main shaft of the centrifuge is accurate or not. Under normal circumstances, people do not pay much attention to the concentricity. The large concentricity of the main shaft tends to cause the bearing to heat up. This requires the production of centrifuge motors to have strong technology and production capacity. In order to save production costs, some centrifuge manufacturers assemble the motor shaft and motor stator themselves, and do not synchronously assemble in the motor manufacturer. Due to the lack of technical guidance, it is easy to produce the concentricity of the main shaft. Tilt, which constitutes the bearing heat.

Of course, the main reasons are analyzed here. There are also some reasons that rely on the user to pay attention to the unbalanced condition when using it. Running in an unbalanced state for a long time can also cause the bearing to heat up. This requires that the centrifuge has unbalance protection measures. The other is to require users to have good usage habits and operate according to the manufacturer's instruction manual.
