1. Notes centrifugal fan selection when (1) should be based on some of the key parameters to select a centrifugal fan, including the terms of the nature of gas transportation, the fan uses. (2) at the time of selection, should take into account the leakage loss calculation error and other aspects in addition to its safety factor should be taken into account, the amount of wind is 01.05-1.1, pressure is 1.1-1.15 for the best, so the fan will not damage. (3) pipe resistance characteristics and the degree of matching characteristics centrifugal fan is also very important and should be able to allow the fan to stabilize the operation. General efficiency of its design conditions shall not be less than about 90% maximum efficiency fan. (4) Select the fan should carefully compare, and to consider the long-run effects of economic, rather than a one-time investment. (5) If you use more wind turbines, you should choose the same type. When the installation specifications 1. centrifugal fan centrifugal fan installed, there should be a place and space to install the required components should be complete, can not have missed, including platform support beam ﹑ ﹑ ﹑ tripod boom and fixed bolts. 2. You must install a spring-type anti-vibration devices, rated deflection of 40mm. 3. Inter fan and duct To install flexible joints, fans at both ends should be run in parallel, if not parallel, the eccentricity can not exceed 25mm. 4. Only in the duct cleaned centrifugal fans, filters installed, bearing lubrication is good and after the end of the centrifugal fan test parameters, in order to officially start the fan. 5. When the fan during the field test, there must be beside the supervision and guidance staff, the amount of wind-site inspection in accordance with the measured value. Stand-alone operation of the test time was one hour, mainly for voltage, current, wind, air pressure, vibration and noise levels, etc. displacement test.
