The installation of duct fans is a process that requires careful planning and operation. The following are detailed installation steps and precautions:
1. Preparation before installation
Select the appropriate fan model: Select the appropriate duct fan model according to actual needs to ensure that it can meet the ventilation needs.
Check the fan and accessories: Ensure that the fan and accessories are intact and prepare the corresponding tools and materials.
Be familiar with safety regulations: Be familiar with relevant safety regulations and operating guidelines to ensure the safety of personnel during the construction process.
2. Selection and treatment of installation location
Select a well-ventilated location: Install the fan in a well-ventilated and easy-to-maintain place to avoid direct exposure to sunlight or extreme temperature changes.
Process the installation location: Level the ground, reinforce the bracket, etc. to ensure that the fan operates stably and reliably.
3. Connection between the fan and the pipeline system
Accurately measure and cut the pipeline: Accurately measure and cut the pipeline according to the design drawings to ensure that the size is accurate.
Sealing treatment: Use special sealing materials to seal the joints to prevent air leakage.
Firm connection: Use appropriate fasteners to firmly connect the fan to the pipeline to ensure good air tightness of the entire system.
4. Electrical wiring and debugging
Follow electrical installation standards: Connect the power cord and control line correctly and follow relevant electrical installation standards.
Full debugging: After installation, fully debug the fan, including checking the direction of operation, adjusting the air volume, etc., to ensure that the fan can work efficiently and stably.
5. Daily maintenance and care
Regularly clean the filter: According to the requirements in the product manual, regularly clean the filter, check the belt tightness, and lubricate key components such as bearings.
Timely check for abnormalities: When abnormal noise or vibration is found, the machine should be stopped and checked in time to avoid small problems from turning into major failures.
6. Special installation steps for circular duct fans
Check the foundation: Check the outer dimensions of the foundation and the center dimensions of each reserved cavity to ensure that the deviation is within the allowable range.
Fix the anchor bolts: Insert the bell mouth of the collector into the impeller and fix it with wire, then hoist the entire rotating group into the predetermined position, install the anchor bolts and preliminarily adjust the gap between the impeller and the bell mouth.
Adjust the coaxiality of the fan and the motor main shaft: Use three dial indicators to align and adjust the coaxiality so that the error is ≤0.05mm, and there should be a 10mm gap between the two backrest wheels.
