Francis turbine installation instructions 1, fans of the series can be divided into four categories according to the direction of airflow: A horizontally mounted suction-type, B-type horizontally mounted exhaust, C vertically mounted suction, explosion-proof Francis fan, D vertical mounting Exhaust style; 2, if the user uses the noise requirements of the occasion, in the connecting pipeline, suction air vents application canvas soft contact; 3, if the vertical suction fan, ventilation type as used on the roof, Francis fan order, may additional hood like roof fan; 4, if the user uses high-temperature applications, such as the use of exhaust fan fire, then I can be converted into the fan and temperature fan. Francis fan is between the axial fans and centrifugal fans between the fan, Francis fan impeller centrifugal motion to allow air to not only do they do the axial movement, housing movement of air mixed axial and centrifugal Two Form, Francis fan stationed inside, so called "mixed." Francis (oblique flow) fan, Shijiazhuang Francis fan, high pressure coefficient than the axial fan, flow coefficient than the centrifugal fan, with the pressure and flow rate are "sort" of the occasion. It fills the gap between axial fans and centrifugal fans of. Along with easy installation features. Francis fan order, up Swiss mechanical and electrical (certified), Shijiazhuang Francis fan ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In liters Swiss electromechanical leadership with the staff warmly welcome all inquiries negotiations to create liter Swiss electromechanical better future.
