Centrifugal ventilators are commonly used ventilation facilities with stable performance and a relatively long service life. However, after long-term operation, their components are prone to wear and failure, and may even stop working properly. Therefore, daily maintenance is of vital importance. The maintenance of centrifugal fans can be divided into the following aspects:

During operation, the fan sucks in a large amount of dust and debris, which will affect its working efficiency and service life. So regular cleaning is essential. First, cut off the power supply, and then use a soft brush to clean the accumulated dust and debris around the fan. In addition, regularly clean the fan blades and air ducts to keep them unobstructed, which helps to improve the operating efficiency of the fan.

The bearing is a crucial component that supports the rotation of the fan. Long-term use will lead to wear of the bearing, so lubrication maintenance is required. Before carrying out lubrication maintenance, clean the accumulated dust and debris at the bearing, and then use special lubricating oil for lubrication. The lubrication cycle depends on the actual situation, but generally, lubrication maintenance is needed once a quarter.

During long-term use, failures or damages are inevitable. Regular inspection maintenance can help detect problems in time. The inspection contents include the start-up and shutdown conditions, abnormal noises during operation, temperature changes, etc. If any problems are found, they should be repaired in time to prevent them from getting worse.

Due to the frequent use of the centrifugal fan, cracks and gaps are easily formed between the fan blades and air ducts during long-term use. Air leakage will result in insufficient air volume, affect the ventilation effect, and even cause certain safety hazards. Regular inspections for air leakage are needed, and once air leakage problems are found, they should be repaired and replaced in time.

Maintenance is the key to extending the service life of the centrifugal fan. By doing all these maintenance work well, the fan can operate stably, achieve good ventilation effect, reduce the occurrence rate of failures and shutdowns, and facilitate production. It can be said that regular maintenance is a very wise and cost-effective choice.
