    概述
          S型單級雙吸泵為中開式離心泵,供抽送清水或物理化學性質類似於水的其它液體之用。被輸送液體溫度不得高於80℃,適用於工廠、礦山、城市給水、電站、農田排灌和各種水利工程。

    結構說明
           本型泵的吸入口與吐出口均在水泵軸心線下方,與軸線垂直成水平方向。檢修時無需拆卸進出口水管及電動機。從傳動方向看去,水泵為順時針方向旋轉(根據用戶需要亦可改為逆時針方向旋轉。)
          泵的主要零件有:泵體、泵蓋、葉輪、軸、雙吸密封環、軸套等。除軸的材料為優質碳鋼外,其餘主要零件為鑄鐵製成。
          泵體與泵蓋構成葉輪的工作室。在進出水法蘭上,製有安裝真空表和壓力表的管螺孔。進出水法蘭的下部,製有放水的管螺孔。
          經過靜平衡校驗的葉輪,用軸套和兩邊的軸套螺母固定在軸上,其軸向位置可通過軸套螺母進行調整。葉輪的輛向力利用其葉片對稱布置、兩麵進水達到平衡。
          泵軸由兩個單列向心球軸承支承。軸承裝在軸承體內,安裝在泵體兩端,用黃油潤滑。
          雙吸密封環用以減少水泵壓水室的水漏回吸水室。
          泵通過彈性聯軸器由電動機直接傳動,必要時亦可用內燃機轉動。
          軸封采用軟填料密封時,為了防止空氣進入泵內和冷卻潤滑密封腔,在填料之間裝有填料環,水泵工作時少量高壓水,通過泵蓋中開麵上的梯形凹槽流入填料腔,起水封作用。(根據用戶需要亦可改裝機械密封。)

    Brief introduction
        Series S Pumps are a single stage, double suction and axially split centrifugal pump and are used to pump clean water or Similar liquids in physical cal and chemical properties. The temperature of the pumped liquid should not be exceeded 80℃. And The pump is mainly suitable for water supply in factories, mines, cities, hydropower stations, various conservancy projects and irrigation in farms,ets.

    Construction description
       The inlet and outet of the pump are both under the centreline of the pump shaft, they are vertical to the shaft centreline andgo to horizental direction. You needn't dismount the outlet and inlet pipes for inspection. Looking from the driven direction therotaty direction is clockwise(Or can change to counterwise as user's requirement).
    Main parts of the pump:(1)Pump casing (2)Pump cover (3)Impeller (4)Shaft (5)Double suction seal ring (6)Shaft sleeve, etc. They are made of cast iron except the shaft material being made of fine steel.
        The impeller working house is composed of pump casing and pump cover. The threaded holes for installing the vacuum gauge and manometer are separately located at the suction flange and the discharge flange. At the bottom of the inlet or outlet flange a drain threaded hole equiped here.
        The impeller checked by statical equilibrium is fixed on the shaft by the shaft sleeves and the shaft nuts, which axial position can be adjusted by the sleeve nuts. And for the axial force of the impeller, it can be adjusted by using the symmtrical distribution of the impeller and the balance of the two sides water.
        The pump shaft is supported by two single redial ball beatings.
        The bearing fitted on the ends of the pump casing is installed in the bearing body and is lubricated by oil grease.
        The double suction seal ring is used to reduce the leaking water from the pressure water house which would flow back to the suction water house.
        The pump is driven by the moto though the flexible coupling(It also can be driven by diesel engine if it is necessary)
        The shaft seal is soft stuff. The packing ring is installed among the packings in order to prevent air from coming into the pump and cooling lubricating sealing case, and while the pump working, it is allowed to let a little high-pressure-water going through the trapeziform concave groove on the horzontally split face of the pump cover and flow into the packing case, function as wate seal(Mechanical seal is available as the customer's requirement.)
