What Precautions Should Be Taken During The Installation Process Of Negative Pressure Air Ducts?

The installation process of negative pressure air duct is a complex and critical task, which involves multiple precautions to ensure the normal operation and optimal performance of the air duct. The following is a detailed discussion on the precautions to be taken during the installation process of negative pressure air ducts:
At first, the choice of installation location is crucial. The negative pressure air duct should be installed near the ventilation opening to effectively exhaust indoor air. At the same time, the installation position should be far away from other equipment and channels to ensure that the air duct can operate normally and maintain sufficient air volume and static pressure. In addition, the installation height is also a factor that needs to be considered. Generally speaking, the installation height should be determined based on the indoor air flow situation, and it is usually recommended to be between 2-3 meters to ensure indoor air circulation.
Secondly, the selection and installation of brackets are equally important. The bracket should be able to withstand the weight of the negative pressure air duct and ensure a sturdy interface with the ground or walls. When installing the bracket, it should be ensured that the bracket is stable and firm to avoid shaking or falling off of the air duct during use.
In addition, electrical wiring is also a part that requires special attention during the installation process. The electrical wiring of the negative pressure air duct should comply with the national electrical safety standards. Before wiring, the power should be cut off to prevent electric shock accidents. When wiring, attention should be paid to the color of the power and motor wires to avoid connecting the wrong line and causing the equipment to malfunction. At the same time, the connection of the grounding wire cannot be ignored as it can effectively prevent the occurrence of electric shock.
When hanging the air duct, a safety turnover rope or electric hoist should be used to fix the negative pressure air duct and ensure its safe lifting onto the bracket. At the same time, connecting the pipeline is also an important part of the installation process, which requires ensuring the normal connection between the pipeline and the negative pressure air duct, and using appropriate sealing materials and fasteners to ensure the sealing of the interface.
In addition, after installation, a comprehensive inspection of the equipment should be carried out. This includes checking whether the bolts and nuts of the equipment are tightened, whether the accessories and power lines are damaged, and whether the air duct is operating normally, whether the speed meets the requirements, and whether the air leakage meets the standards. These checks can ensure the safety and stability of the negative pressure air duct, reducing the possibility of malfunctions during use.
In addition, there are some other precautions to pay attention to. For example, during the installation process, attention should be paid to the temperature of the environment to avoid installation at high or low temperatures. After installation, attention should be paid to the distance between the exhaust and air supply outlets, ensuring that the distance is not less than 30 centimeters to prevent backflow of exhaust air. At the same time, to prevent the influence of humid heat sources, the negative pressure air duct should be placed as much as possible in a place that is neither damp nor affected by high temperatures.
In summary, the installation process of negative pressure air ducts requires attention to multiple aspects, including careful operation in various aspects such as position selection, bracket installation, electrical wiring, and equipment inspection. Only by ensuring that each step is correct can we ensure that the negative pressure air duct can operate normally and perform better.
