 SWF Francis fan selection low-noise low-noise method SWF Francis fan selection method SWF Francis fan low noise compact structure, easy installation, reliable operation, so as Francis fan of using the user, when our usual selection of how to choose it? Xiao Bian today to introduce you to a method: In fact, the selection of Francis fan exhaust fan there are many ways, such as: press the dimensionless characteristic curve selection, press the logarithmic curve selection, press the dimensionless characteristic curve or performance Table selection, variant selection, according to the pipe network resistance selection, etc., there are still online selection system through the Web and use specialized software selection selection. Methods complicated. But we ordinary people usually used the method on two kinds, that is familiar with and master the dimensionless performance tables have specialized selection and fan selection software in two ways. Francis fan selection, the first mixed according to the required amount of wind turbines, total pressure of these two basic parameters, you can have a dimensional model performance table exhaust fan through the fan, the fan model and determine the number of the machine; then combined fan use, process requirements, the use of occasions, choose the type of fan, models and structural materials, etc. to meet the required operating conditions exhaust fan service, and strive to make the fan's rated flow and pressure rating, as close to the flow and process requirements pressure. Francis fan concern market trends and enhance the competitiveness of enterprises continued Francis fan called good quality performance using Francis fan Francis fan needs to pay attention to what the course is different from other fans, it does not exist other fans high prices, difficult to install, difficult to maintain issue. Francis turbines in daily use, you need to master the use of certain methods and techniques, you can let your fans to work more smoothly. Axial fans and centrifugal fans Francis fan has been on the market is different from, Francis fan blade size than those two big fans, and ventilation, ventilation coefficient is larger than the latter two. In everyday use, you must take effective measures to protect the fan will not be damaged, because the fan blades are the most important part, and only part of the maintenance of good fans, fans will be normal and stable work. Likewise, you usually use in the process of Francis fan exhaust fan, be sure to pay attention to the fan noise is large, if noisy, then you will need to carry out oiling Francis fan, and wipe with a lubricating bearing part.
