What is the role of blower?

Blower is to rely on the input of mechanical energy, improve gas pressure side by side to send gas machinery, it is a driven fluid machinery.
Blower widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings ventilation, row dust and cooling; industrial boilers and furnaces and ventilation fan; air conditioning equipment and household appliances in the cooling and ventilation; grain drying and sending; wind tunnel wind source and hovercraft inflated and propulsion.
Blower and working principle of the turbine compressor are basically the same, just because of the low gas flow rate, pressure has little change, generally do not need to consider changes in the specific volume of gas, namely the gas as incompressible fluid handling.
Blower classification:
Blower classification can be based on the direction of gas flow, is divided into centrifugal, axial flow, oblique flow and cross flow type and other types.
According to the flow direction of the air flow into the impeller, the fan is divided into axial flow fan, centrifugal fan and oblique flow (mixed flow).
Blower according to use points is pressed into the local wind machine (hereinafter referred to as pressure type fan) and flameproof motor is arranged in the outer part of the flow passage or in the passage, the flameproof motor is arranged in the explosion-proof sealing cavity out of local fan (hereinafter referred to as the fan out).
Blower performance parameters
The performance parameters of fan mainly include flow rate, pressure, power, efficiency and speed. In addition, noise and vibration of the size of the main fan design indicators. Also known as the air volume flow, in unit time through the gas volume of Fan said, also known as the wind pressure is a gas in the fan pressure value, static pressure, dynamic pressure and total pressure. Power is the input power of the wind turbine and shaft power. The ratio of the effective power and the shaft power of the wind turbine is called efficiency. Fan total pressure efficiency of up to 90%.
The future of wind turbines
Wind turbine industry will further enhance the gas fan aerodynamic efficiency and system efficiency and use efficiency, to reduce the consumption of electricity; the moving blade adjustable axial flow fan instead of large centrifugal blower; reduce fan noise; improve the exhaust gas, exhaust dust blower impeller and casing wear resistance; change speed regulation and automatic regulation.
