Before selecting fan, you should understand the situation of the domestic production and product quality fan, fan varieties such as the production of special purpose specifications and a variety of products, new product development and promotion etc., should give full consideration to the environmental requirements in order to select the best fan. According to the physical delivery of gas ventilator, Hebei different chemical properties induced draft fan manufacturers, select the fan for different purposes. Such as transport of explosive and flammable gases should be selected proof fan; row dust or transport of pulverized coal or pulverized coal dust should be selected row fan; transport of corrosive gases should choose preservative fan; working in high temperature applications or conveying high temperature gas temperature should be chosen ventilators. Selection is a highly technical work, the specific selection method is also a lot of Shandong draft fan manufacturers, is varied according to the induced draft fan factory in Tianjin, such as by logarithmic curve selection, press the dimensionless characteristic curve or performance table selection, press the dimensionless characteristic curve selection, etc., the method is still a lot, but you have to master any professional knowledge in order to choose the better. Typically Industrial Boiler Fan motors are constant speed operation, and then by changing the opening of the tailgate door entry draft fan to adjust the amount of wind. To improve the efficiency of the fan motor lead, and save energy. One can speeder on the induced draft fan motor coat. Adjust the speed control device according to the situation of work to meet the speed requirements of the working conditions. The second is to use the drive for transformation induced draft fan induced draft fan manufacturers do not have to make big changes to the original system, adding a drive cabinet. Boiler Fan motor frequency control is not implemented before the general use of "step-down start," and the normal operation of the motor full pressure, running at full speed, while the induced draft fan size of the wind through the throttle to adjust. In general, the degree of throttle opening is 50% to 80%, the motor can only be run at full capacity, the low work efficiency of the motor, resulting in great waste. The basic principle of frequency control technology is directly proportional relationship between the motor speed and the power supply input frequency; the power supply frequency by changing the motor speed to achieve the purpose of changing the motor.
