Circulating water cooling tower fan reducer
Thread Content
What is the model of the reducer for the cooling tower fans in circulating water systems of type FL-47, and which manufacturer offers the best ones? Is it necessary to perform dynamic balancing on the blades after repair and installation, and how is it done?
I couldn’t find an answer to the first question – is there a nameplate? As for the second question, if the maintenance is not due to excessive vibration of the equipment, then dynamic balancing is not necessary. Does your factory have the facilities to carry out dynamic balancing?
FL-47: with a blade diameter of 4.7 meters; the names used by different manufacturers vary, for example, Baoding uses LF-55 and so on. The blades are installed by part number and do not require dynamic balancing. If it is not operating properly, static balancing can be performed. Baoding and Shanghai in China are relatively good.
LF-47 is a reducer designed for cooling towers; the number 47 indicates that the diameter of the fan is 4700 millimeters. If the blades are properly labeled after removal, no balancing is required. Incorrect installation can cause vibration in the fan. The fan blades produced by Dezhou Benuo Fans can be interchanged freely, and technical consultations are welcome at 18615342179
