Bearing temperature exceeded, Francis fan pictures, 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 lubrication, Francis fan specifications, is to make the movement portion not in direct contact friction, fire exhaust fan Francis, 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, Francis fan, or heat can not be taken away by the lubricating oil, leaving the bearing temperature. Francis fan performance options to edit fan performance is within the performance range of the most efficient, according to traffic divided into five characteristics, subject to the selection according to the performance table fan qualified for performance under full pressure rated flow value does not exceed ± 5%. Performance is performance standard selection table state, standard state atmospheric 101325Pa, t = 20 Ψ = 50% relative humidity of the air condition, the wind turbine installation can be divided into vertical or horizontal.
