Working And Application Of High-pressure Fans

In mining production, high-pressure fans are often used. According to their working characteristics, high-pressure fans can be divided into centrifugal fans and axial flow fans. At present, the use of high-pressure fans is still very wide. Let us follow the staff of the fan factory to understand the working and application of high-pressure fans.

When the impeller rotates, due to the action of centrifugal force, the wind vane causes the gas to move forward and outward, thus forming a series of spiral movements. The air between the impeller blades accelerates the rotation in a spiral shape and squeezes the gas outside the pump body into the side groove (sucked in by the air inlet). When it enters the side channel, the gas is compressed and then returns to the impeller blades to accelerate the rotation again. When the air passes through the impeller and the side groove along a spiral track, each impeller blade increases the degree of compression and acceleration. As the rotation proceeds, the kinetic energy of the gas increases, which further increases the pressure of the gas passing along the side channel. When the air reaches the connection point between the side groove and the discharge flange, the gas is squeezed out of the blades and discharged from the pump body through the outlet muffler.

High-pressure blowers have been widely used in environmental water treatment, such as sewage aeration, to meet the oxygen required by aerobic microorganisms in activated sludge and the conditions for full contact and mixing of sewage and activated sludge, thereby degrading various organic matter in the water to achieve the purpose of sewage purification. They can also play a stirring role, as well as electroplating tank liquid stirring and aquaculture, all of which play the same role. There are also folding machines, creasing machines, paper cutters and other machines in the printing industry.
