Centrifugal Air Blower 75KW 42m3/min 0.6Mpa Low price hot sales

 The structure and characteristic of the fan

          The model fan is mainly used for conveying air, can also be used for other working condition of transport non-corrosive, non-viscous industrial gases, etc., with high efficiency, low noise, smooth operation, less wearing parts and installation, operation, simple maintenance and so on.
          Fan for grade nine (impeller) single suction double support structure, driven by motor through coupling blower., when looking from the motor blower rotor is counterclockwise, vertical upward into the outlet, fan inlet and outlet are all round.
          Fan is mainly composed of casing, rotor, bearing box.
          Casing made of cast iron casting and anti-corrosion, conducive to the antivibration and absorb the noise, the chassis of points up and down the level, convenience of transportation, installation and maintenance, and help the dismantling of the rotor.Casing combining face, finishing the scene when Ann split for not stem sealing glue sealing, and through bolts and positioning pin fastening.To facilitate the upper casing, lug has a bulge on the shell.
          Rotor spindle by 45 # steel jing, for the closed impeller impeller, is made of alloy steel, 16 mn (Q325), blade used for veneer after bending type, and front coil, plate welding and become, after annealing treatment before finishing, to eliminate the welding stress.By the dynamic and static balance correction after rotor assembly, to ensure that the fan running smoothly.
          Bearing box is made of cast iron and points in the structure, the side with the semicircle of the flange and casing connection, fan adopts rolling bearing, bearing grease lubrication, circulating water cooling structure.Grease brand: lithium base molybdenum disulfide, both ends of bearing box respectively labyrinth sealing and dustproof sealing ring, thus can prevent the grease leakage and external intrusion magazine.
         Cooling system: including water cooled bearing box, water hose.Circulating water through the water pipe in bearing in the bearing parts, reduce the bearing temperature.28 ℃, cooling water temperature < 0.2 ~ 0.3 MPa water pressure, water consumption of 0.5 ~ 1 m3 / h.
