Adjustable-vane axial-flow fan
The adjustable vane axial flow fan is widely applicable to the iron and steel metallurgy industry (sintering dust removal and flue gas desulfurization, denitrification, pressurization or induced draft systems), the power generation industry (boiler air supply and induced draft as well as desulfurization and denitrification systems), large mine ventilation systems, etc. It main features include high efficiency, low energy consumption, stable and reliable performance, a wide adjustment range, stable operation under variable working conditions with high efficiency, a long overhaul interval, simple maintenance, low cost, low vibration value, and low noise.
The equipment adopts advanced three-dimensional flow design theory and CFD flow field analysis technology, enabling are aerodynamic design of the impeller to achieve highly optimized aerodynamic characteristics, with a total pressure efficiency of up to 90%.
The equipment uses a hydraulic control to adjust the blade angle of the impeller, with an adjustment range of 20%-110% of the design performance, while maintaining high-efficiency operation; it is suitable for a medium temperature range of 20-200℃.
The equipment adopts thin oil station forced oil lubrication and air cooling, with a low bearing temperature rise (≤35℃) and a long bearing service life (≥80000h).
The annual utilization rate of this equipment reaches from than 99%, and an overhaul is carried out once every 4 years of operation.
The equipment has a compact structure, making inspection and repair convenient and quick.
The equipment has low vibration value (≤2,5mm/s) and low noise ≤85dB(A).
