It is a kind of gas circulation machinery. Its use makes it easier for tunnels, engineering, equipment, etc., and according to the different use, it is divided into many types, such as: centrifugal passage, axis circulation, high section, etc., then selectingHow to choose the right factory staff based on years of work experience, here are the principles of selection.
The flow and wind pressure of the fan are usually provided by the sample. The gas temperature in the sample is slightly different from the standard status of the fan. The standard state refers to: the clean air with a density of 1.2kg/m3 of the gas temperature of 50%of the relative humidity of the gas temperature 20 is 50%of the constant humidity.It can be seen that the formula of the fans (diameter of the impeller) is the same, and the flow values ??of different operating conditions are equal: the rated flow Q0 (M3/ s) in the standard state is equal to the system under the conditions of the system) According to the gas temperature density under use conditions, the air pressure is calculated to calculate the air volume of the system fan, according to the requirements of the cement industry dust removal technology engineering specifications, the air volume of the fan is 1.10 and 1.15 times the airlift air volume of the system.The resistance of 1.2 times the resistance, and the two parameters of the air volume pressure should be met at the same time. If the data volume pressure and the data in the fan performance table are large or can only meet the single parameterThe regulation of the pressure requirement for the selection of the cement heat work process should also be considered. It should also consider factors such as the material decomposition process and the evaporation process of the material water. In addition to the above steps, the air volume pressure should be calculated.Calculate to determine a reasonable ventilation to meet the requirements of the process system.
