Centrifugal fans are the most common mechanical ventilation, it works almost the same compressor and turbine, but due to the low gas flow rate, pressure changes little centrifugal fan, gas specific volume change under normal circumstances do not need to be considered, That the gas as an incompressible fluid handling. Jilin centrifugal fan flow rate during its installation, there are several steps required to note the following with the gas-turbine with a look: 1, centrifugal fan site assembly, the cutting surface on the base should be properly protected and should not be There rust or operation when the base is placed horizontally on the basis of the application paired oblique horn leveling. 2, the bearing should be in close contact with the base, vertical not horizontal should not exceed 0.2 / 1000, measured with a spirit level on the spindle horizontal bottom level should not exceed 0.3 / 1000, at the level of the equatorial plane bearing the standard instrument measurement. 1. Notes centrifugal fan selection when (1) should be based on some of the key parameters to choose Chongqing sell centrifugal fan centrifugal fans, including aspects of the nature of gas transportation, the fan uses. (2) in the selection of Tianjin cooled centrifugal fan, you should take into account aspects of air leakage losses, calculation errors, etc. In addition, it's a 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 cause 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.
