Fan impeller partial wear more than the thickness of what should be carried out or what?
A ventilator is a machine that relies on the input of mechanical energy to raise the pressure of the gas to send the gas side by side. It is a driven fluid machine. The exhaust pressure is less than 1.5 * 10 PA. The fan is widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings ventilation, dust and cooling, boilers and industrial furnaces, ventilation and air conditioning, cooling and ventilation equipment and household appliances in the air, grain drying and sending wind, wind tunnel and the inflator and hovercraft propulsion.
Boilers and industrial furnaces, ventilation and air conditioning; cooling and ventilation equipment and household appliances in the air; grain drying and selected; wind tunnel and air inflator and hovercraft propulsion. The working principle and the turbine compressor fan is basically the same, just because the gas flow rate is low, the pressure change is very small, generally do not need to consider the change of gas volume, namely gas as incompressible fluid treatment. The impeller working surface hardness of HRA composite ceramic layer is more than 86 (toughened alumina composite), partial wear parts using two sintered silicon nitride toughened ceramic or zirconia toughened alumina ceramics, the maximum can reach above HRA94, its resistance to erosion of particles can at least improve ordinary tungsten carbide welding, spraying and welding bulk alloy powder welding and other conventional treatment methods of more than 5 times, 100 times higher than 16Mn steel; thickness of 1.5mm ceramic actual use has reached five years, the average wear less than 0.2mm
Generally, it is better to dust the factory with the draft fan. Comparison of blower and draft fan: before blower is used in furnace and equipment, draft fan is used in kiln and equipment. A little bit, you can say that the blower pressure is generally greater than the fan. Draft fans are widely used in factories, mines, tunnels, cooling towers, ventilation, dust removal and cooling of vehicles, ships and buildings
