Multistage blower
Using a three-dimensional meridional flow, combined impeller, and composite blade technology, the impeller has high aerodynamic efficiency.
There is no guide ring at the impeller inlet, effectively improving the flow at the impeller inlet.
Wing-type return channel blade design technology results in low losses and higher conversion of static pressure energy.
The multistage centrifugal blower is a type of blower equipment characterized by a series of multistage impellers. Adjacent impellers are connected by guide vanes. The pressure range is from 15 kPa to 0.2 MPa, and the compression ratio is 1.15-3. This product is widely used in wastewater treatment, molten blast furnaces, mineral flotation, and chemical gas production, among other fields. It can convey air and special gases, featuring oil-free operation, low pulsation, and the ability to produce clean and dry gas. The equipment consists of a main unit (including the blower, motor, and combined base) and related accessories. It uses either direct connection or belt drive. Impeller materials include aluminum alloy and high-strength alloy steel. The main shaft is made of carbon steel or alloy steel, and the sealing device uses a labyrinth structure to prevent leakage. This equipment is suitable for applications with a flow range of 15-500 cubic meters per minute, can operate continuously for over one year, and has a noise level below 85 dB(A). Some models employ a structure combining triple-ring vortex meridional surfaces with wing-shaped recirculation devices, achieving aerodynamic efficiency of over 78%. These models support variable frequency control and intelligent monitoring functions. The bearing system can be configured as either rolling or sliding type, with lubrication options including lithium-based grease lubrication and pressurized oil lubrication.
Product Overview.
The intake and exhaust housings of the blower, as well as the recirculation device, are fully matched through parameter optimization and the impeller, thereby reducing losses in the streamline design.
2. Using a ternary vortex axial plane, composite impeller design, and composite curve technology, the aerodynamic efficiency of the impeller is significantly improved.
3. The absence of a guide ring at the impeller inlet effectively improves fluid flow at the impeller entrance.
4. Advanced design technology for airfoil recirculation device blades minimizes losses and increases the conversion efficiency of static pressure energy.
5. Blower performance is optimized using flow analysis technology, achieving a variable efficiency of over 78%.
The same blower can operate at both 50Hz and 60Hz speeds. It offers a wide range of adjustment options and excellent performance.
After strict dynamic balancing, the rotor demonstrates extremely low vibration amplitude, very high reliability, and relatively low overall noise levels.
The shared base can be installed with vibration-damping pads, eliminating the need for anchor bolts. This saves time and effort and reduces the cost of foundation construction.
The fan has an advanced and rational structure with few wear parts, making installation, operation, and maintenance very simple.
Main Uses.
Water treatment, wastewater treatment, biogas recovery, vacuum dust removal, air knife drying, flotation and mineral processing, galvanizing and electroplating, aeration of liquids and baths, process gas conveyance, paper-making and printing industries, air combustion (desulfurization, carbon black, blast furnace smelting, etc.).
