Description

technical field [0001] The invention belongs to the field of electromechanical equipment, and in particular relates to a double-shaft centrifugal fan. Background technique [0002] Fan is the customary abbreviation for gas compression and gas conveying machinery in my country. Usually, fans include ventilators, blowers, and wind generators. Gas compression and gas delivery machinery are machines that convert rotational mechanical energy into gas pressure energy and kinetic energy, and transport the gas out. The main structural components of the fan are the impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, 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 drive the turbine to rotate, so as to use centrifugal force and negative pressure effect to discharge the stale hot air in the room. Fans are related to the transmissio...
