Shandong fan impeller manufacturer, we produce Marriott fan impeller is made of high quality vinyl ester resin and advanced production technology, corrosion-resistant features, compact in structure impeller design to meet the high speed operation of the fan. Before the product is generally used to arc-type impeller blades, the fan impeller after the use of large-scale wind turbine blade airfoil, the lower collection efficiency for coal-fired boiler induced draft fan can arc or flat blades. Blade design air volume, fan, light weight, high energy efficiency, long blade life. 8-16 piece impeller can be customized according to the customer different number of models of air flow. Current use of flat-type centrifugal fan blades more durable products. Replacement glass ladle iron backward production technology, solve small ordinary glass steel impeller air flow, easy to fall apart. Shandong blower wheel manufacturer, the company excellent quality and excellent service, won the unanimous endorsement of the industry and consumers, through the shaft of the motor power to the fan impeller, the impeller rotates to transfer energy to the air, which produces under the rotating action centrifugal force, the extension of the fan impeller blade air to spread around this time, the greater the fan impeller, the greater the energy received by air, that is, the fan pressure head (pressure) increases. If a large impeller cutting small, does not affect the amount of wind, air pressure will decrease. The principle of centrifugal fan, centrifugal fan gas between the blades in the impeller rotates, centrifugal force obtained by the kinetic energy (dynamic pressure) is discharged from the impeller periphery, through spiral-shaped body of the guide, so that the outlet flow to the fan, thus a negative pressure in the central part of the impeller to make external air flow into complementary, so that the fan can exhaust gases.
