Centrifugal Blower Fan
The shel of inlet and ouitlet, and retum channel of blower are fully adapt to impeller, The streamine design reduces loss.
The impeller is designed by three-dimensional meridian plane and compound curve technology,enjoys high efficiency.
The impeller intake seal-inducer improves inlet fluidity of impeller.
The airfoil retum-flow blade can reduces loss ,gets high static pressure.
The bloweris consists of stator. rotor.dnving device and so on.It has onesuction and two supports. The rotor consists ofmulti-stage impellers. Motor and blower are installed independently, or are installed on the same common base according toowner's demand (indicating before order).Motor and blower are direct connected with coupling (The mini-type blower connect withbelt). Watching from the tal of motors (For the mini-type blower, it is shaft protraction), the blowers is clockwise rotation.
The stator is vertical split type structure, which is consists of the inlet chamberintermediate casing and discharge scroll case, these parts make up of the gas channels withbolts. The inlet chamber, intermediate casing and discharge scroll case are founded usinghigh quality castiron and rosin model, having small distortion after strict anneal dispose.Stator with high precision and high coaxial can insure stable operation of rotor assembly.
Rotor is consists of impellers, main shaft, shaft sleeve, half coupling and soon. The main shaft makes use of the high quality carbon-steel, and carries throughquenching and tempering. After assembly, the rotor was dynamically balanced toensure steady and reliable running.Based on the requirement, casting-impeller and welding-impeller are adopted. Casting-impeller isprecisely cast with high strength aluminum-alloy. And the welding-impeller is welded of a hub ,cover andwanes ,in the course of welding, heat treatment should be done several times to eliminate weldingstress. Each single impeller is dynamically balanced and tested with high speed after preciselymachining.
