    產品結構及用途
    關風機又稱旋轉閥、鎖氣器,通常呈星型結構(如圖I所示)是由帶有數片葉片的轉子葉輪、殼體、密封件及減速器、電動機等組成。
    當上部料倉的物料靠自重落下充填在葉片之間的空隙中,隨葉片的旋而在下部卸出,因此,關風機可以定量而連續地卸料(如圖2所示)。
    關風機可以用在收集物料系統中,作為料倉的卸料器(如圖4所示),它特別適用于粉料、小顆粒物料,在正負壓差吸送過程中將物料分離排出,因而深受化工、制藥、干燥、糧食、水泥、環保、電力等行業的工程項目選用。

    The structures and the use Commissioner Fan is also called rotary valve, air lock, usually is of the structure of star (as the picture1), is made up by some pieces of the rotor blade impeller, shell, seals, reducer and motor, elc. After materials in the upstream silo fall down by gravity to filf in with the gap between the leaves, they will be unloaded with rotation of the blade from the lower part .Therefore, Commissioner Fan can unload thematerials quantitatively and continually(as picture 2). Commissioner Fan is used in pneumatic system(as picture 3), for the compression or vacuum conveying system.
    Commissioner Fan can feed materials to chute smoothfy and continuafly, to assure that the ratio of air and solid jn the pneumaic system, the sOlidls more steady, so to make the pneumatic conveying work normally, at the same time, it also can cut off the upper and lower pressure to lock the gas. Thus, Commissioner Fan is the important part which is commonly used in the pneumatic conveying syslem.
    Commissioner Fan can be used in materials collection system as the discharger ofthestorage bin (as picture 4). It is applicabfe to the powder and the particle material It is suitable for positive/negative pressure diffetial suction syslem, so it is alwavs selecled to be used by the chemical,pharmaceutical, dry, food, cement, environmental protection, electric power and other sectors Of the projects.


    一、丹港牌關風機的上、下法蘭口基本是方形或圓形,也可以由用戶選定。
    二、耐磨損封閉型轉子葉輪改關風機特點是轉子葉片的端部采用特殊耐磨材料制成,能保證葉片端部與殼內壁的良好接觸,并且磨損后可方便地調節葉片端部,使其仍然與殼體內部保持良好接觸,具有更好的鎖氣性能。
    三、耐高溫型它所輸送物料的溫度可達300攝氏度兩端軸承與葉輪有一定隔離,能防止超細粉料與軸承接觸。

    1 .Dangang Brand Commissioner Fan is up and down flanged. Faces are square or round. It can also be fabricatedas per thespecial requirements from customer.
    2.This dosed rotor was made by exterior grinding material,can assure very well contacting with casing
    3.External installed &Temperature and pressure resistance type can be fed by materials in 300℃ temperature. Bearing on twosides can't contact powder.



    關風機排料量G按下式計算:Discharging capacity is calculated as per the foilowing formula
    G:0.06V.N.Y.R.K(噸/小時) G: 0.06V N Y R K(ton / h)
    V-關風機容積(升/轉)V-volume of commissioner fan(I / r)
    N-關風機轉速(轉/分)rotation speed of commissioner fan
    Y-關風機容積效率:顆粒狀物料r=0.8;粉狀物料r=0.5-0.6
         Volume efficiency: r=0.8  forgranular materic  r=0.  5~0.6 for powder mater iai
    R-物料容量(噸/立方米)Density (ton / m3)
    K-修正系數,一般取0.7~0.8 k-rectification coef-ficient.it is 0.7~0.8 usually
