Fan impeller is generally made of what material?
The wind turbine blade material is basically made of polyester resin, vinyl resin and epoxy resin, thermosetting resin matrix and E glass fiber, S glass fiber, carbon fiber reinforced, through manual placement or resin injection molding process of composites.
The fan is a mechanical device that relies on the mechanical energy input to raise the pressure of the gas to send the gas side by side. It is a kind of driven fluid machinery.The fan is the abbreviation of the gas compression and gas transportation machinery in our country. The fan is usually called: fan, blower, wind generator. A gas compression and gas delivery mechanism is a machine that converts rotating mechanical energy into gas, pressure and kinetic energy, and transports it.
The main structural components of the fan are impeller, shell, air inlet, bracket, motor, pulley, shaft coupling, muffler, transmission parts (bearings), etc..Unpowered fan is the use of natural wind and indoor and outdoor temperature difference caused by air heat convection, to promote the rotation of the turbine, so as to use centrifugal force and negative pressure effect, indoor fresh hot air exhaust.The fan is related to the energy consumption of the transmission and distribution system, and is the key part of the building energy efficiency. According to the national air conditioning equipment quality supervision and Inspection Center for many years, fan testing shows that many fans in rated conditions have problems, therefore, in strict accordance with product standards, production and manufacture of fans.
