In order to better achieve the effect, how to ensure that the negative pressure fan achieves the effect during the installation process can refer to the following aspects:
1. It is best to install the negative pressure fan in the middle of the room, away from the areas where the temperature is hot and the smell of smoke is concentrated; if there are conditions, try to install it on the core air of the cooling environment. Location: It can be installed on indoor walls, windows, roofs, and indoor pillars. However, attention should be paid to the installation environment to ensure that the air is smooth and fresh. In particular, it cannot be installed in an air outlet with odor or smelly gas. at. If there are not enough doors or windows, a professional air supply system needs to be installed. The exhaust volume of the air supply system should exceed 100-150% of the total exhaust volume of the negative pressure fan.
2. Pay attention to the stability when installing the negative pressure fan. The centrifugal fan must be installed stably when it is standing up. It cannot be installed upside down or with a tilted angle of more than 30 degrees.
3. The quality of the negative pressure fan is important. Generally, the server must be determined first and it can be installed in time. A good negative pressure fan such as Jiafeng can extend the service life and effect and reduce the equipment failure rate.
4. The negative pressure fan installation support frame must be made of angle steel with a specification above the national standard 4*4, and must be painted with anti-corrosion paint for anti-rust treatment. The bearing points of the installation support frame can support all negative pressure The weight of the fan and the body weight of the two maintenance personnel, each corner of the negative pressure fan must be fixed firmly to avoid vibration and resonance noise when the negative pressure fan is working.
5. After the negative pressure fan is installed and fixed, attention should be paid to the sealing between the negative pressure fan and the surrounding gap to prevent rainwater from leaking into the room on rainy days. You can use endurance boards to fill large gaps, and structural adhesive sealing is small. Clearance.
6. The negative pressure fan must be plugged in before it can work effectively. Please ask a professional welder to complete the power distribution equipment. The automatic switch must have leakage protection, leakage protector, current overvoltage protection and other functions. The used cables and wires To be able to withstand the load of motor current, all terminals should be wrapped with electrical tape to insulate, and all wires should be buried in wire troughs and conduits.
