  • Product description: This page details the technical parameters of type 4-72 Grain reserve fan, product performance, dimension diagram, air volume, wind pressure, motor power, our company is 4-72 Type Grain reserve fan ma

  Use: 4-72 The fan can be used as indoor ventilation and ventilation for general factories and large buildings, conveying air and other non-spontaneous gases that are harmless to the human body and non-corrosive to steel materials. No viscous substances are allowed in the gas, and the dust and hard particles contained are not much greater than 150mg/m3. The gas temperature must not exceed 80 ℃.

  Type: From one side of the motor to face, impeller clockwise rotation, known as the right Cyclone machine, to "right" means; the impeller rotates counterclockwise, which is called the left cyclone, expressed as "left". The outlet position of the fan is indicated by the outlet angle of the chassis. Machine number №2.8~6 out of the factory are made into a type, the use of units according to the requirements, and then installed into the required outlet position, order does not need to be noted, machine number №2.8 outlet position adjustment range of 0°~225°, Interval is 45°, machine number №3.2~6 outlet position adjustment range of 0°~225°, The interval is 22.5°; The adjustment range of the №8~12 outlet position of the machine number is 0°~225°, the interval is 45°, and the №16 of the machine number outlet, 20 is made of 0°, three fixed position, and the 180° is not adjusted, and the order should be indicated. 

  Structure: The machine number of №2.8~6 type 4-72 fan is mainly composed of impeller, chassis, air inlet and other parts with direct motor, machine number for №6~20 in addition to the above parts there are transmission parts. (1) The impeller is welded from 10 rear tilt wing blades to the middle of the curved wheel cover and plate type roulette, all of which are made of steel plate, and through static and dynamic balance correction, good air performance, high efficiency and smooth operation. (2) The chassis is a worm form welded with ordinary steel plates. The chassis is made of two different types. The №2.8~12 chassis is made into a whole and cannot be disassembled. №16, 20 of the chassis made of two open, along the middle sub-water level is divided into two halves, bolted. (3) The inlet is made into a convergent streamlined integral structure, which is mounted on the side of the fan, and the cross section with axial parallelism is a curved shape, which can make the gas enter the impeller smoothly and the loss is small. (4) The transmission part consists of a spindle, a bearing box, a rolling bearing, a belt wheel or a coupling.
