SWF (A) -I / II / III Type Francis fan machine number: 3 # -13 # air volume: 3000-95420m3 / h Total pressure: 143-11200Pa features: conical wheels, twisted blades, air inlet with a collector, high pressure, air volume, high efficiency, compact structure, low noise, small size, equipped with two-speed motor, can be adjusted wind, air pressure applied by the shift: hotels, restaurants, shopping malls, office buildings, stadiums and other senior civil pass exhaust pipe pressurized air supply and industrial and mining ventilation place Francis fan bearing temperature exceeded, it is one of the main bearing damage. The main cause of the high bearing temperatures are the following: Poor (1) the quality of lubrication. The purpose of lubricating Francis turbine installation, is to make the movement portion not in direct contact friction Francis fan applications, and the formation of friction between solids and liquids. If the number of inadequate or poor quality lubricants, static and dynamic part of the direct causes friction and heat, or heat can not be taken away by the lubricating oil, leaving the bearing temperature. Cangzhou Francis fan, up Swiss mechanical and electrical, Francis fan Use ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. Cangzhou Francis fan, up Swiss mechanical and electrical, Francis fan ventilation and air conditioning use is liter Swiss Mechanical and Electrical Equipment Factory (www.dzsrxfkt.com) this year introduced a new upgrade, the above picture is for reference only, please call the telephone or pictures on this page, For the latest information, contact: province.
