Fan is a pneumatic conveying equipment in the production process of small flour machine, which is an indispensable existence. However, different equipment, different processed products have different requirements for fans, so how to choose the right fan when users buy small flour machinery?
1. When choosing, it is necessary to pay attention to more comparisons, combined with factors such as the working resistance and air volume of the wind network to ensure stable work.
2. The wind pressure and air volume are recommended to be 15 to 20% and 25 to 30% higher than the wind pressure and air volume of the air network design. Moreover, in the selection of fan transmission form, we should not focus on direct transmission, and the appropriate transmission form should be determined according to the selected fan working parameters.
3. In order to reduce noise and take into account the possible deviation between the actual pressure, air volume and performance curve of the fan, it is generally recommended that the speed of the fan should be 2500 to 2700 rpm, which should not be too high or too low to affect the operation.
Choosing the right fan for small flour mill is an important condition to ensure the normal and economical operation of the ventilation system. The so-called correct selection mainly refers to the selection of fans for different purposes according to the nature and purpose of the gas to be conveyed, and the selected fan should meet the air volume required by the system, and the wind pressure should be able to overcome the resistance of the system, and work within the range of the highest efficiency or economic use.
