When using centrifugal fans, many operators often encounter the issue of excessively high bearing temperatures. If the root cause is not identified and resolved, the equipment cannot operate normally. Therefore, when the fan’s bearings show signs of overheating, it is crucial to determine the cause and address it.

The main reasons for high bearing temperatures in fans typically include several factors, which operators need to understand in detail to effectively troubleshoot the issue. These factors include bearing damage, incorrect selection of lubricating oil or grease, excessively high or low oil levels, insufficient cooling water, misalignment between the motor and fan, and rotor vibrations. When high bearing temperatures are detected, operators should systematically check these aspects. Identifying the specific cause is essential for effectively solving the problem.

To address the issue of high bearing temperatures in fans, operators can take several measures such as replacing the bearings, selecting appropriate lubricants, adjusting the oil level, increasing the amount of cooling water, aligning the radial and axial levels, and balancing the rotor.

In summary, high bearing temperatures in centrifugal fans are often due to improper operation. Therefore, operators must use the equipment correctly in their daily routines and perform regular maintenance to ensure the normal operation of the fans. This will make maintaining the fans much easier.
