In the daily life of people, the existence of exhaust fans has become very common, especially the use of exhaust fans in building fire protection construction, which is of concern to all consumers. In the buildings designed and built at this stage, the exhaust fan is an indispensable existence and is an important equipment in the current fire protection standard. However, due to many factors, the exhaust fan may have many problems when it is installed and used. Among them, deformation and damage are the most common and most important, and there are many reasons for this problem.
Impeller problem
This is a problem that may occur in a long exhaust fan. When the impeller is damaged or the impeller is contaminated with too much stain, the stability of the impeller rotation will be broken. The imbalance of operation will cause the exhaust fan to vibrate under the action of centrifugal force. When the time is right, the deformation will occur, and the exhaust fan will be damaged seriously.
2. Bearing
The same is true for bearings, which can become severely worn after prolonged use. Bearings that do not match will oscillate, slowly causing deformation and bending of the bearing.
3. Installation issues
The non-standard installation is one of the main willingness to cause various problems. Many exhaust fans are caused by various problems after installation.
