In the process of operation, the plastic impeller fan needs an effective centrifugal force, so that the wind can form an outward movement effect according to a certain rule, so that it can finally achieve its purpose. In fact, this series The movement is caused by a certain principle. In normal operation, it must have a certain understanding of its principles, so that it can work better when working.
During the operation of the plastic impeller, the centrifugal force will cause the wind vane to directly move the gas forward. This will directly form a series of spiral movements, which will be caused by the impeller blade during operation. The air between them spirally accelerates and rotates the gas outside the pump body into the side slot (inhaled through the suction port). When it enters the side channel, the gas is compressed and then returned to the impeller blade to accelerate again.
The plastic impeller fan is running. When its air passes along a spiral track through its impeller and side slot, each impeller blade will effectively increase the degree of compression and acceleration, and to a certain extent will follow. As it rotates, the kinetic energy of the gas increases, and the plastic fan causes the pressure of the gas passing through the side channel to increase further. When the air reaches the junction of the side slot and the discharge flange (the side channel narrows at the outlet), the gas is extruded out of the vane and exits the plastic fan pump through the outlet muffler.
Plastic impeller fan is mainly based on the principle of its centrifugal force to a certain extent. In the process of operation, its airflow enters the fan's impeller and flows radially. Its products include centrifugal fans, centrifugal blowers and centrifugal compressors.
The utility model relates to an air conditioner fan impeller. The utility model comprises an end ring, a plurality of blades, and a middle plate connected with the blades. The end ring, the blades and the middle plate are integrally injection-molded, and the middle plate is disposed between the two end rings, in the middle plate and the two end rings. Two sets of identical blades are arranged between the blades, and the blades are arranged vertically along the circumferential edge of the middle plate, and the two sets of blades are evenly arranged in a staggered manner, and the thicknesses of the side walls and the bottom plate on the blade, the middle plate and the end ring are equal.
