  產品型式:本公司號有NO2.8、3.2、3.6、4、4.5、5、5.6、6、6.3、7.1、8、10、12十三種?？芍瞥捎倚妥笮齼煞N型式，葉輪順時針旋轉，稱為右旋風機。以“右”表示，葉輪逆時針旋轉，稱為左旋風機，以“左”表示。風機的出口位置，以機殼的出風角度表示。4-72NO2.8-10出廠時均做成多種型式，可根據使用單位要求安裝成所需的位置，即出風口位置調整范圍0°~225°間隔是22.5°或45°，即（0°、45°、90°、135°、180°、225°）共六種。NO7.1-10根據用戶需求制成一種方向角度。風機的傳動方式為C式。
  結構特點:本風機主要由葉輪、機殼、進風口、機架、軸承箱等皮帶傳動而組成。葉輪：由10個后傾斜的機翼型葉片、曲線型前盤和平板后盤組成。并經過動平衡校正，氣動性能，故運轉平衡、振動小、效率高、壽命長等特點。機殼：用鋼板焊成蝸型殼體。進風口：制成整體（全部模具成型），裝于風機的側面，于軸向平行的戴面未曲線形狀，能使氣體順利進入葉輪，且損失較小。傳動組：由主軸、軸承箱、聯軸器等。主軸由優質鋼制成，軸承箱整體結構，采用滾動軸承，分為水冷和油冷兩種。

• 4-72C centrifugal fan

  4-72C centrifugal fan can transport air and other non-self-igniting, harmless to the human body, non-corrosive to steel. No viscous substances are allowed in the gas, and the dust and hard particles contained in the gas are not more than 150 mg/m3. The gas temperature should not exceed 80 °C. The fan is widely used in industrial ventilation enterprises, large buildings, hotel restaurants and other indoor ventilation and smoke exhaust. Product type: The company has NO2.8, 3.2, 3.6, 4, 4.5, 5, 5.6, 6, 6.3, 7.1, 8, 10, 12 and thirteen. It can be made into two types: right-handed and left-handed. The impeller rotates clockwise and is called a right-handed fan. Expressed as "right", the impeller rotates counterclockwise, called the left-handed fan, and is represented by "left". The exit position of the fan is expressed by the air outlet angle of the casing. 4-72NO2.8-10 is made into various types at the factory, and can be installed to the required position according to the requirements of the unit of use. That is, the position of the air outlet is adjusted from 0° to 225°, and the interval is 22.5° or 45°, that is (0 There are six kinds of °, 45°, 90°, 135°, 180°, and 225°. NO7.1-10 is made into a direction angle according to user requirements. The fan is driven in the C mode. Structural features: The fan is mainly composed of impeller, casing, air inlet, frame, bearing box and other belt transmission. Impeller: consists of 10 rear-tilted airfoil blades, curved front discs and flat rear discs. After dynamic balance correction and aerodynamic performance, it has the characteristics of balanced operation, small vibration, high efficiency and long service life. Housing: welded with a steel plate into a volute casing. Air inlet: made into a whole (all mold molding), installed on the side of the fan, the axially parallel wear surface has no curved shape, which enables the gas to smoothly enter the impeller with less loss. Transmission group: from the main shaft, bearing housing, coupling and so on. The main shaft is made of high-quality steel. The overall structure of the bearing housing is made of rolling bearings and is divided into water-cooling and oil-cooling.
