Centrifugal fans are the most common mechanical ventilation, it works almost the same compressor and turbine, but due to low gas flow fume hoods Shanxi centrifugal fan, little change in pressure, the gas specific volume changes under normal circumstances Shanxi high pressure centrifugal fans need to consider size, ie the gas as an incompressible fluid handling. In the course of its installation, there are several steps 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, there should be no corrosion or operation When the base is placed horizontally on the basis of centrifugal fan, paired oblique horn leveling applications. 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. Centrifugal fan vibration and noise is too large (1) phenomenon and harm a) phenomenon: the fan vibration, noise; 2) Hazard: Causes fan running unstable, easily damaged; noise through the bracket, duct air conditioning control is passed to the environment, noise pollution.
