The main cause of high temperature centrifuge motor heating

Because of the high speed of the high-speed centrifuge , it is easy to cause the motor to heat up. Usually, we need to pay attention to the operation of the machine from this time. Because there are several reasons for the motor bearing heat, it is necessary to analyze the details carefully. Shanghai Li Xin Jian centrifuge manufacturers experienced now tell you about the possible cause of the relevant reasons.

·First, it may be due to overload or overload, it may be a current problem such as a cooling fan, or it may be due to the heat generated by mechanical friction, but the main problem is whether the bearing can be authentic, and some users are low for low prices. The price of the bearing, resulting in bearing heat, hot, so that the bearing burned and so on. Therefore, we first emphasize the need to buy authentic (imported) bearings. Such as: SKF bearings: domestic as long as a dozen yuan, and the original imported SKF to nearly one hundred yuan, the same brand, different origin, the quality is not the same.

·Second, we must pay attention to the lubrication of the machine, choose high-quality high-temperature lithium grease, the difference of lithium grease is another major reason for 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.

The Shanghai Lixinjian centrifuge is analyzed here for the main reason. There may be some reasons for relying on the user to pay attention to the unbalanced condition. If the machine is operated in an unbalanced state for a long time, it can also cause the bearing to heat up. Therefore, this requires that the high-speed centrifuge has unbalanced protection measures. The other is to let users have good habits, according to the manufacturer's instructions. In this way, the centrifuge can be operated better.
