Industrial fan

Fan is a kind of driven fluid machinery, which relies on the input mechanical energy to increase the gas pressure and discharge gas. Fan is the abbreviation for gas compression and transmission machinery in China. Generally speaking, fans include fans, blowers and wind turbines.

Fans are widely used for ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and for ventilation and induced draft of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and selection of grain, wind source of wind tunnel, inflation and propulsion of hovercraft, etc.

The main structural components of the fan are impeller, casing, air inlet, support, motor, pulley, coupling, muffler, transmission parts (bearing), etc.

The unpowered fan uses the air heat convection caused by the natural wind force and the indoor and outdoor temperature difference to drive the turbine to rotate, thus using the centrifugal force and negative pressure effect to exhaust the indoor stale hot air.

The fan is related to the energy consumption of the system transmission and distribution, and is a very critical part of building energy conservation. According to many years of fan testing conducted by the National Air Conditioning Equipment Quality Supervision and Inspection Center, many fans have problems under rated working conditions, so it is necessary to produce and manufacture fans in strict accordance with product standards.
