The maintenance of centrifugal fans can be divided into these parts

Centrifugal fans are commonly used ventilation equipment. Although their performance is relatively stable and their service life is long, some of their components may wear and fail after prolonged use, even causing the fan to malfunction. Therefore, daily maintenance and upkeep are essential. The maintenance of fans can be divided into several parts, which will be introduced one by one below.

1. Cleaning and maintenance.

During use, the fan may inhale a lot of dust and debris, which can affect the efficiency and lifespan of the fan. Therefore, it is necessary to regularly clean and maintain the fan.

Firstly, it is necessary to cut off the power supply, and then use a soft bristled brush to clean the dust and debris around the fan. In addition, regularly cleaning the fan blades and air ducts to keep them unobstructed is beneficial for improving the operational efficiency of the fan.

2. Lubrication and maintenance.

The bearing of a centrifugal fan is a crucial component that supports the rotation of the fan. Prolonged use can cause bearing wear, therefore lubrication and maintenance are necessary.

Before performing lubrication and maintenance, it is necessary to remove dust and debris from the bearings, and then use specialized lubricating oil for lubrication. The lubrication cycle depends on the specific situation, but generally requires quarterly lubrication maintenance.

3. Check and maintain.

During long-term use, the fan may experience some malfunctions or damages. In order to detect problems in a timely manner, it is necessary to regularly inspect and maintain the fan.

The content of inspection and maintenance includes the start stop status of the fan, abnormal noise during operation, temperature rise, and so on. If any problems are found, they need to be repaired in a timely manner to prevent the problem from worsening.

4. Air leakage inspection.

Due to the frequent use of centrifugal fans, long-term use can easily cause cracks and gaps between the blades and the air duct.

Fan leakage can lead to insufficient air volume, affecting ventilation effectiveness, and even posing certain risks. It is necessary to regularly check the air leakage situation, and repair and replace it in a timely manner if any air leakage problems are found.

Maintenance is an important means to extend the service life of centrifugal fans. Regularly taking measures such as cleaning, lubrication, inspection, and air leakage inspection has many benefits. It can not only ensure the stable operation of the fan within its effective life, bring good ventilation effect, but also reduce the incidence of failures and shutdowns, bringing convenience to production. It can be said that regular maintenance and upkeep are very cost-effective.
