The fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. The blower is a Chinese habit abbreviation for gas compression and gas conveying machinery, and the blower generally comprises a ventilator, a blower and a wind driven generator. Fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and for ventilation and draught of boilers and industrial furnaces and kilns; cooling and ventilation in air conditioning equipment and household appliances; the main structural components of the fan are an impeller, a shell, an air inlet, a bracket, a motor, a belt pulley, a coupling, a silencer, a transmission part (a bearing) and the like. The unpowered ventilator utilizes natural wind power and air heat convection caused by indoor and outdoor temperature difference to push the turbine to rotate, so that the hot air which is not fresh indoors is discharged by utilizing centrifugal force and negative pressure effect, and the ventilator is a very key part for building energy conservation, which relates to the transmission and distribution energy consumption of the system. According to the years of fan detection of the national air conditioning equipment quality supervision and inspection center, the problem exists in many fans under rated working conditions, so that the fans need to be produced and manufactured strictly according to the product standard requirements.
