air bearing blower

air bearing blower application:

ZENGKUN air bearing centrifugal blower is widely used in:

Raw material pressure conveying (grinding or granular raw material transportation), food and medicine processing engineering (simplified and food, medicine, etc.) , metal processing engineering (paste/non-ferrous transportation and heat treatment, sludge drying treatment), thermal power generation (coal grinding/FY-ash, fuel gas delivery (Oxidation)), sewage/wastewater treatment project (sewage wastewater aeration) /GRIT, BACKWASH backwashing area), cement industry, chemical industry, semiconductor industry, brewing industry, biopharmaceutical industry, fermentation industry, paper industry, textile printing and dyeing industry, etc.

1. Structural Principle Comparison:

Traditional Fans Are Mostly Driven By Gears Or Belts, Equipped With Gearboxes, Couplings, Belts And So On. There Are Efficiency Losses In The Transmission Process. Air Suspension Blower Adopt Direct Connection Technology, Impellers And Motor Rotors Are Directly Connected, The Transmission Efficiency Reaches 100%.

2. Bearing Power Comparison (100KW Fan As An Example)

Traditional Roots Fan And Multi-Stage Centrifugal Fan Bearings Adopt Deep Groove Ball Rolling Bearings. The Power Consumption Of Bearings Is About 1.5KW During Operation. Most Single-Stage High-Speed Fans Use Tilting Pad Oil Film Bearings, Which Produce About 15KW Power Consumption In High-Speed Rotating Type. Air Bearings Have No Physical Contact And Friction, And Only Exist Wind Friction Loss, About 200W.

3. Motor Efficiency Comparison

The Traditional Squirrel Cage Induction Motor Has Poor Speed Regulation Performance, Small Starting Moment, And Efficiency Is Close To 90% At Rated Power. The Efficiency Decreases Sharply At Variable Power Output, And Only 72% At Rated Power 50%. The Efficiency Of ZK High-Speed Permanent Magnet Motor Is 97%. Permanent Magnet Motor Can Be Adjusted In A Wide Range, Even At 50% Power Output, The Efficiency Is Still 92%.

4. Comparisons Of Impeller Efficiency

Roots Blower Fan Is A Closed Two-Dimensional Flow Impeller, Which Uses Multi-Stage Compression, Low Flow Efficiency, And Variable Efficiency Is Only About 75%. ZK Air Float Fan Adopts Advanced Three-Dimensional Flow Impeller Technology, Single Compressor Compression, Efficiency Up To 92%.

5. Frequency Conversion Speed Regulation System + PLC Control

Frequency Conversion Efficiency Up To 97% Of The Converter And High-Speed Motor Perfect Match, Can Meet The Fan 50% - 100% Wide Range Of Flow Accurate Regulation, To Ensure That The Fan In The Changing Conditions Of Efficient Operation. PLC Reserves Remote Communication Ports, And Uses Modbus-RTU, Modbus-TCP/IP Mode To Communicate With Central Control System Remotely To Realize The Remote Operation Of Fan. Through The Selection Of Coordinating Cabinet, The Parallel Coordinated Operation Of Multiple Fans Can Be Realized.
