Fan production: intermittent GDF duct fan

Fan manufacturer: Fan is a machine that relies on the input of mechanical energy to increase the gas pressure and discharge the gas, it is a driven fluid machinery. Wind turbine is the customary abbreviation of gas compression and gas transmission machinery in China, and the commonly referred to fans include ventilators, blowers, and wind turbines.

Fan production: intermittent GDF duct fan

Fan manufacturers: fans are widely used in the ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and the ventilation and induced air of boilers and industrial furnaces; cooling and ventilation in air-conditioning equipment and household appliances; Drying and selection of grains, inflating and propulsion of wind tunnels and hovercraft, etc

Fan manufacturer: Gas compression and gas conveying machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports gas out.

Fan manufacturer: The main structural components of the fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, silencer, transmission parts (bearings), etc.

The unpowered ventilator uses the natural wind force and the air heat convection caused by the temperature difference between indoor and outdoor to push the turbine to rotate, so as to use centrifugal force and negative pressure effect to discharge the stale hot air in the room. [2]

The fan is related to the energy consumption of the system and is a very critical part of building energy saving. According to 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.

When the fan starts to work, the vibration of the bearing part is very small, but with the extension of the running time, the dust in the fan will be unevenly attached to the impeller, gradually destroying the dynamic balance of the fan, so that the bearing vibration gradually increases, once the vibration reaches the maximum allowable value of the fan 11mm/s (the maximum allowable value expressed by the amplitude value is as follows), the fan must be shut down for repair (remove the dust accumulation, redo the dynamic balance). Because it is very dangerous at this time, users must not force it. When the vibration of the fan is close to the dangerous value, there is a vibration measuring instrument will give an alarm.
