Difference between centrifugal fan and blower, mainly following points, as follows: a difference: How it works is the use of curved centrifugal fan blades, then by centrifugal force gas to the cabinet office, and Roots blower, then using a 8-shaped blades, is squeezed by squeezing the gas to the outlet. Difference between the two: Site Requirements centrifugal fan is mainly used in low pressure, wind than larger establishments, and Roots blower is used in the high pressure, the wind than the smaller places. Third difference: less precision manufacturing precision manufacturing centrifugal fan, manufacturing precision Roots blower is relatively high. Four differences: parameters of centrifugal fan load demand is constant, so it is a constant fan, its air pressure change is small, and has a square torque characteristics. Roots blower fan is a constant flow, the main argument is the wind, and the wind changed very little. And high pressure air blower is conveying air volume and the number of revolutions is proportional. Five difference: noise Roots blower noise than running a large centrifugal fan.

Notes centrifugal fan selection when (1) should be based on some of the key parameters to choose centrifugal fan, including aspects of the nature of gas transportation, the fan uses. (2) in the selection, should take into account the leakage loss, the 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 to 1.1-1.15 for the best, so the fan will not damage. (3) pipe network resistance characteristic and centrifugal fan characteristic matching degree is also very important and should be able to allow the fan to stabilize the operation. General efficiency of its design case, should not be less than 90% of maximum air efficiency. (4) Select the fan should carefully compare, and to consider the long-term effects of the economy, rather than a one-time investment. (5) If you use more wind turbines, you should choose the same model. 2. centrifugal fan maintenance (1) 2,000 hours of operation a. Remove surface dirt, for bearings, bolts, inlet and outlet, couplings, belt to be checked, whether the issue. b. for lubrication should be checked, lubricants and seals were replaced. (2) 8000 hours operation including the above Ganzhou chiller, but also on the impeller shaft and parts to be checked, if the problem should be repaired, not replace.
