What do you know about the differences between Roots fans and high pressure fans? BelowRoots FansI'll take you through it.
The two impellers of the Roots fan rotate in opposite directions, because the gap between the impeller and the impeller, the impeller and the casing, and the impeller and the wall plate is extremely small, thus forming a vacuum at the air intake, and the air enters into the intake cavity under the action of the atmospheric pressure, and then two of the blades of each impeller and the wall plate and the casing form a sealing cavity, and the air of the intake cavity, in the process of the rotation of the impeller, is continuously brought to the exhaust cavity by the sealing cavity formed by the two blades. The air in the air intake cavity, during the rotation of the impeller, is continuously brought to the exhaust cavity by the sealing cavity formed by the two blades, and because the impellers in the exhaust cavity are meshed with each other, thus squeezing out the air between the two blades, and thus continuously running, the air is continuously transported from the air intake to the air outlet, and this is the whole working process of the Roots fan. This is the whole working process of Roots fan. Therefore, the fan has little vibration and low noise. Its impeller and shaft as a whole and no wear and tear of the impeller, the fan is durable and unchanged, can be a long time continuous operation. Fan volume utilization rate is large, high volumetric efficiency, and compact structure, the equipment method is dynamic and changeable. Roots fan bearing selection is also more reasonable, the bearing transport articulation is reasonable, and then extend the fan is with life!
The high-pressure fan is due to the two do not contact each other rotor in the cylinder for the same speed reverse movement, to promote the gas flow from one side to move to the other side. High-speed gas flow to the exhaust port near the exhaust port connected to the moment, because there is a higher pressure of the gas back, then the pressure in the working volume suddenly rises, and will be transported out of the gas. High-pressure Roots blowers rely on synchronizing gears at the shaft end of the rotor to keep the two rotors meshed. Each concave curved surface part on the rotor and the inner wall of the cylinder form the working volume, and the gas is taken away from the suction port in the process of rotor slewing, when the two rotors work alternately in sequence. By increasing the power, strengthening the rotor group, increasing the volume, increasing the speed, adjusting the impeller clearance method makes the air compression inside the gas chamber increase, the pressure rises. When the impeller transforms, because of the effect of centrifugal force, the wind vane promotes the gas to move forward and outward, and then constitutes a series of spiral movement. Impeller blades between the air was spiraled to accelerate the rotation and the pump body outside the gas squeezed into the (inhaled by the suction port) side channel, when it enters the side channel in the future, the gas is tightened, and then back to the impeller blades to accelerate the rotation again. When the air along a spiral trajectory through the impeller and the side channel, each impeller blade adds the degree of tightening and acceleration, followed by the rotation, the kinetic energy of the gas increases, so that the gas pressure along the side channel through the further increase. When the air arrives at the connection point between the side channel and the discharge flange (the side channel narrows at the outlet), the gas is squeezed out of the vane and discharged out of the pump body through the outlet muffler.
