The following issues need to be paid attention to during the installation of low noise centrifugal box:
1. Basic requirements: The foundation of low noise centrifugal fans should be horizontal and strong, and its height is not less than 200mm.At the same time, the steel frame must be fixed on the concrete base, and a porous shock absorbing rubber pad should be installed between the steel frame and the concrete base.
2. Import and export pipeline connection: Fan in and export pipeline connection should be adjusted to make it naturally consistent. If it is not forcibly connected, a soft connection can be used if necessary.At the same time, in order to ensure the stability of the fan during the runtime, the pipelines of the air inlet and outlet should have separate support, and the weight of the pipeline cannot be pressed on the fan.
3. Installation and debugging: Before installation, conduct a comprehensive inspection of each component of the fan to ensure that each component is firmly connected and the transmission parts are flexible.After installation, the manual tray should be checked to check whether the fan is flexible and whether there is a collision.In order to prevent the motor from burning, the fan must be activated when it is not loaded. If the situation is good, the load is gradually increased.
4. Vibration reduction and silence: During the installation of low noise centrifugal fans, shock absorbers or shock absorption mats should be used to reduce the vibration of the fan.At the same time, the entrance and export of the fan should be connected using an irregularly burning material hose to isolate the vibration of the body and reduce noise.
5. Electricity: During the installation process, the electrical connection of the fan should meet the safety requirements, including ground protection and overload protection.
