Its main components are a shell, impeller, crankshaft, air inlet and exhaust port. The centrifugal force generated during the rotation of the impeller, the air is thrown out of the impeller, collected in the shell, and the high pressure is discharged from the air outlet. When the air impeller is discharged to form negative pressure, the external air is sucked into the added fan. It has a great impact on the performance of the blade type impeller fan. Do all the forward routes of the rotation path at the front of the blade, and then execute all the lines from the blade itself, with two tangential intersection angles β Russia said that, β> Blade mentioned at 90 °, β< The 90 ° radial blade is called forward blade, β Near 90 ° is called. Use the blade as the flow gas to leave less energy loss, less noise, and efficient rotation after light collision. However, when the blade is thrown into the lower gas flow rate, the dynamic pressure gas obtained after the reduction of static pressure is low enough to be discharged from the fan.
When using the front blade, the air circulation is not smooth, violent impact, large energy loss, high noise and relatively low. However, when the blade is thrown to the front of the high gas flow rate, a larger static pressure can be obtained at the outlet of the blower. Radial blade features a forward and backward facing between. A fan with the same width, the outer surface of the screw is smooth and increases from the end to the end. The cross section of the gas is converted into static pressure head during the flow process by increasing the dynamic pressure of the gas. 0.98? 2.94kPa (100? 300mmH2O), which is called the pressure of centrifugal fan generated between pressure fans; When the pressure is less than 0.98kPa (100mmH2O), it is called low pressure turbine; When the pressure>2.94kPa (300mmH2O), it is called high pressure air. The dust removal system generally uses pressure fans, and the pressure generated by centrifugal fans generally does not exceed 14.71kPa or more (1500mmH2O)
