Rotation speed refers to the speed at which the fan rotates, usually calculated by the number of revolutions in 1 minute, referred to as rpm. The speed is related to the number of turns, wire diameter, fan blade impeller outer diameter and bottom diameter, blade shape and bearing used. AC cooling fan

 Ventilators are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; cooling and cooling in air conditioning equipment and household appliances Ventilation; drying and selective delivery of grains; air source of wind tunnel and inflation and propulsion of hovercraft. The working principle of the fan is basically the same as that of the turbo compressor, except that the gas flow rate is low, the pressure changes little, the speed increases, and the air volume increases accordingly. The speed value represents the air volume to a certain extent. Under certain conditions, the higher the speed, the greater the conflict force: if the fan is used for a long time, the fan will overstand, vibrate, and the center of gravity will be unstable, which will cause the fan A collision or conflict occurs between the blades and the fan frame, and then noise is generated. AC cooling fan

Subsequently, the increase in fluid mechanics causes the negative pressure energy to be transformed into velocity energy, and the incoming vapor is discharged according to the air outlet, and the necessary air pressure is generated in the middle of the centrifugal impeller, because the passage is under air pressure, so that the external vapor is in Under the effect of atmospheric pressure, it is immediately refilled, and under the effect of continuous rotation of the centrifugal impeller, it is continuously discharged and refilled with steam, which exceeds the goal of continuous air shower. When the single-stage high-speed centrifugal fan is working,

DC cooling fan noise processing method: select the appropriate fan specifications and parameters according to the actual situation. Don't blindly pursue speed. Clean the dust and refuel the fans regularly to reduce conflicts between fans.

Waterproof: For some products that handle humid environments or work in water, we need to consider the waterproof level of the cooling fan; the above 5 items are the reliability factors to be considered for the cooling fan itself.

AC cooling fan

Fans are widely used in tunnels, underground garages, high-end civil buildings, metallurgy, factories and mines and other places for ventilation and high-temperature smoke exhaust. According to different purposes, commonly used fans can be roughly divided into the following types: centrifugal compressors; power station fans; general centrifugal fans; general axial fans; Roots blowers; sewage treatment fans; high temperature fans; air conditioning fans; fire fans; Mine fan; tobacco fan;

In addition to these, there are also some installation factors, odor factors and other cooling fans that need to be adjusted. If the customer proposes, we will take corresponding countermeasures.
