Detail
Model :4 -72 centrifugal fan
Features : versatile, good ventilation effect , low noise
Uses: Suitable for industrial and mining plants, research institutes and large public buildings ventilation, as both the input gas , also used as an output gas .
Use of the environment : air transportation is not available spontaneous combustion , harmless , non-corrosive gases for steel . Adhesive materials are allowed inside the gas contained in the dust and hard particles is not greater than 150mg/m3. Gas temperature must not exceed 80 ℃.
Features: Machine No. 4-72 type centrifugal fan NO2.8-6 is mainly allocated by the impeller, housing, air inlet , such as the Ministry of Direct electric motor , NO6.-20 In addition to the part of the group as well as transmission parts.
  1 ) impeller of an airfoil backward curved blades welded to the wheel cover in the middle of the flat type of roulette are carbon steel plate (B4-72 with a cast aluminum alloy ) manufacturing , and after the static and dynamic balance correction , air good performance, high efficiency , smooth operation.
 2 ) chassis is welded with high-quality carbon steel plate snail body . Enclosure made of two different forms , NO.2.8-12 chassis made whole, can not open , NO16, chassis 20 can be made removable , were divided into two halves along the carved , bolted .
 3 ) made convergent inlet streamline the overall structure, mounted on the fan side , parallel to the axial cross-section shape of the curve , the gas can smoothly enter the impeller, and a smaller loss .
 4 ) the transmission part of the spindle , bearing housing , bearings, pulleys or couplings components.-js9905.com金沙网站
