300S58 300S58A 300S58B 12SH-9中開泵（長沙東方工業泵廠 銷售熱線：137-55-15-40-94 q-q：4-7-5-9-4-6-4-64 李經理）S型泵的吸入口與吐出口均在水泵軸心線的下方，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，其余主零件由鑄鐵、鑄鋼、不銹鋼制成。
﹒泵體與泵蓋構成葉輪的工作室，在進出法蘭上，裝有安裝真空表和壓力表的管螺孔。進出水法蘭的下部，裝有放水的管螺紋孔。
﹒經過靜平衡檢驗的葉輪，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。葉輪的軸向力利用其葉片對稱布置、兩面進水達到平衡。
﹒泵軸承為向心球軸承。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力室的水漏回吸水室。
﹒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傳動。
﹒軸封為軟填料密封（根據需要也可裝機密封）。為了防止空氣進入泵內和冷卻潤滑密封腔，在填料之間裝填料環，水泵工作時少量高壓水，通過泵蓋中開面上的梯形凹槽流入填料腔，起水封作用。
CONSTRUCTION DESCRJPTION
The inlet and outlet of the pump are both under centerline of the pump shaft, they vertical to the shaft centerline and in horizontal direction, You needn’ t dismount the outlet and pipes for inspection, Looking from the driven direction the S type rotary direction is clockwise (or can change to clock wise as user’s requirment)
Main parts of the pump;
(1)Lower Gasing (2)Upper Casing (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 (or Impeller bronze. Shaft s. s).
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 equipped here.
The impeller checked by statical balancing is fixed on the shaft by the shafl sleeves and the shaft sleeve nuts, which axial POSTTTION can be adjusted by the sleeve nuts, And for the axial force of the impeller, it can be by using adjusted the symmetrical distribution of the impeller and the balanoe the two-sides water.
The pump shaft is supported by two single radial ball bearing.
The bearing fitted on the ecds of the pump casing is installed in the bearing boby and is I ibricated by oil grease.
The double suction seal ring is used to reduce the leakage water from the pressure water house which would flow back to the suction water house.
The pump is driven by the motor through the flexible coupling (It also can be driven by dicsel engine if it is necessary)
The shaft seal is packing or mechanical seals, the packing ring is installed among the packing 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 going through the trapezioel groove on the horizontally split face of the pump cover sealing pipe and flow into packing or mechanical seals case, function as water sral
