There are several reasons for the heat of the centrifuge motor bearing, and detailed analysis should be carried out in detail.
*, may be due to overload or overload, may be the current problem of cooling fans, and may be due to the heat generated by mechanical friction, but the main problem is whether the bearing can be authentic, some users set low-cost bearings for low prices , resulting in bearing heat, hot, so that the bearing burned and so on. Therefore, we first emphasize the need to buy authentic (imported) bearings. The bearings used in the centrifuge series are all imported SKF bearings.
Second, we must pay attention to the lubrication of the machine, the selection of high-quality high-temperature lithium grease, the difference of lithium grease is another major cause of bearing heat. In addition, you should check with your meticulous situation, assuming that the mechanical friction will be accompanied by noise, and the mechanical parts will have obvious wear. If the bearing is loose, then the bearing should be in a problem and the bearing needs to be changed. It is recommended to install authentic imported bearings. The centrifuge is a high-speed equipment. High-speed bearings are required to use good bearings. The high-quality authentic bearings can ensure the long-term normal operation of the centrifuge, and the service life can last for more than 10 years.
Third, the concentricity of the centrifuge spindle can be accurate. Under normal circumstances, people pay less attention to the concentricity. The tendency of the spindle concentricity is very easy to form the bearing heat. This requires the centrifugal motor production to have strong technology and production capacity. Some centrifuge manufacturers in order to save production costs, the motor shaft and the motor stator are assembled by themselves, and are not assembled synchronously at the motor manufacturer. Due to lack of technical guidance, the spindle concentricity is easy to occur. Tilt and form the bearing to heat up.
Of course, the main reason is analyzed here. There are also some reasons for relying on the user to pay attention to the unbalanced situation, and long-term operation under unbalanced conditions can also cause the bearing to heat up. This requires that the centrifuge have unbalanced protection measures. The other is to let users have good habits, according to the manufacturer's instructions.
