Working Principle Of Annular High-pressure Blower

When the impeller rotates, due to the 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). After 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 through 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.
