Description

Features

It has the characteristics of solid anti-corrosion performance, long service life, and stable operation.

Generally, the PP/FRP centrifugal exhaust fan blower can be used on occasions with corrosive gas to discharge corrosive gas. The gas conveyed cannot contain viscous substances, dust, and hard particles less than or equal to 150mg/m3, gas temperature less than or equal to 60 degrees, and relative humidity less than or equal to 100%. Fiberglass centrifugal fans are not suitable for high-temperature places.

Working principle

As the name suggests, the centrifugal exhaust fan blower is a centrifugal fan made of PP/FRP anti-corrosion material. The working principle is that when the motor rotates to drive the fan impeller to turn, the gas between the blades in the impeller also rotates, and is thrown out under the action of centrifugal force. Gas, the gas flow rate increases, so that the gas in the flow converts kinetic energy into static pressure energy, and then as the fluid is pressurized, the static pressure energy is converted into velocity energy, and the gas is discharged through the exhaust port, and it is formed in the middle of the impeller. In order to achieve a certain negative pressure, because the inlet is negative, the outside air is immediately filled under the action of atmospheric pressure, and the gas is continuously discharged and filled under the action of the continuous rotation of the impeller, so as to achieve the purpose of continuous air blowing. Under the same power, wind pressure and air volume are generally inversely proportional. Under the same power, if the wind pressure is high, the air volume will be relatively low, and the wind pressure will be lower if the air volume is large so that the power efficiency of the motor can be fully utilized.

Use

It is widely used in chemical, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment, and other occasions containing corrosive gases.
