What is the difference between a high-pressure ring fan and a Roots blower?
When the air reaches the point of connection between the side slot and the discharge flange (the side channel narrows at the outlet), the gas is squeezed out of the blade and discharged through the outlet muffler.
When the air passes through the impeller and the side slot along a spiral track, each impeller increases the degree of compression and acceleration, and as the rotation progresses, the kinetic energy of the gas increases, resulting in a further increase in the gas pressure along the side channel.
The air between the impeller blades is spirally accelerated and the gas outside the pump body is squeezed into the side slot (when sucked into the side of the suction port). When it enters the side channel, the gas is compressed and then reverts between the impeller blades
When the impeller rotates, due to the role of centrifugal force, the wind vane to promote the forward and outward movement of gas, thus forming a series of spiral movement.
