進口雙吸離心泵 

英國進口雙吸離心泵Double suction centrifugal pump

進口雙吸離心泵概述：
雙吸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(zhuǎn)（根據(jù)用戶需要亦可改為逆時針方向旋轉(zhuǎn)）。
﹒泵的主要零件有；泵體、泵蓋、葉輪、軸、雙吸密封環(huán)、軸套等。除軸的材料為優(yōu)質(zhì)碳鋼外，其余主零件由鑄鐵、鑄鋼、不銹鋼制成。
﹒泵體與泵蓋構(gòu)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(jīng)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(diào)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(nèi)、安裝在泵體兩端，用黃油潤滑。
﹒雙吸密封環(huán)用以減少水泵壓力室的水漏回吸水室。
﹒泵通過彈性聯(lián)軸器由電動機直接傳動，必要時亦可用內(nèi)燃機傳動。
﹒軸封為軟填料密封（根據(jù)需要也可裝機密封）。為了防止空氣進入泵內(nèi)和冷卻潤滑密封腔，在填料之間裝填料環(huán)，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。
 　

進口雙吸離心泵結(jié)構(gòu)特點
　1. 結(jié)構(gòu)緊湊 外形美觀，穩(wěn)定性好，便于安裝。
　2. 運行平穩(wěn) 優(yōu)化設(shè)計的雙吸葉輪使軸向力減小到zui低限度，且有優(yōu)異水力性能的葉型，并經(jīng)精密鑄造，泵殼內(nèi)表面及葉輪表面極其光華具有顯著的抗汽蝕性能和高效率。
　3. 軸 承 選用軸承保證運行平穩(wěn)，噪音低，使用壽命長。
　4. 軸 封 選用BURGMANN機械密封或填料密封。能保證8000小時運行無泄漏。
　5. 安裝形式 裝配時不需調(diào)整，可根據(jù)現(xiàn)場使用條件。分立式或臥式安裝。
　6. 加裝自吸裝置，可實現(xiàn)自動吸水，即不需安裝底閥，不需真空泵，不需倒灌，泵可以啟動。

進口雙吸離心泵應用范圍：
　  泵的零件用不銹鋼板壓制，經(jīng)激光焊接而成，并有多種牌號的不銹鋼可供選用，因而雙吸泵的用途十分廣泛，主要適用于輸送各種潔凈水及輕腐蝕液體，可用于住宅供水及增壓,工業(yè)鍋爐給水,空調(diào)系統(tǒng),循環(huán)體會水,水處理和反滲透系統(tǒng),食品工業(yè),醫(yī)藥工業(yè)用水

Imported double suction centrifugal pump

British imports of double suction centrifugal pump Double suction centrifugal pump

Introduction of imported double suction centrifugal pump:

The suction port and the outlet of the double suction pump are below the axis of the pump, and are perpendicular to the axis. No need to disassemble the inlet and outlet water pipe and motor. From the direction of transmission, the pump is clockwise rotation (according to user needs can also be changed to counter clockwise rotation).

The main parts of the pump are: pump body, pump cover, impeller, shaft, double suction seal ring, shaft sleeve, etc.. In addition to the shaft material for high quality carbon steel, the rest of the main parts made of cast iron, cast steel, stainless steel.

The pump body and the pump cover constitute the impeller of the studio, in the inlet and outlet flange, equipped with a vacuum gauge and pressure gauge tube. The lower part of the water inlet and outlet flange is provided with a water outlet pipe threaded hole.

After the static balance of the impeller, with the shaft sleeve and both sides of the sleeve nut fixed on the shaft, the axial position can be adjusted through the sleeve nut. The axial force of the impeller is symmetrically arranged on both sides of the impeller.

Pump bearing radial ball bearing. The bearing is installed in the bearing body and is installed at both ends of the pump body.

- double suction is used to reduce the water leakage from pump pressure chamber back to the suction chamber sealing ring.

The pump is directly driven by the motor through the elastic coupling, and can also be used when necessary.

Seal for soft packing seal (also can be installed as required). In order to prevent the air from entering the pump and cooling the lubrication seal cavity, the packing ring is filled between the filler and a small amount of high pressure water when the pump works.

Imported double suction centrifugal pump

1 compact structure, beautiful appearance, good stability, easy to install.

2 smooth operation optimization design of double suction impeller makes the axial force decreases to a minimum, leaf type with excellent hydraulic performance, and precision casting, the internal surface of the pump shell and the impeller surface extremely Guanghua has significant anti cavitation performance and efficiency.

3 bearing selection of internationally renowned brand bearings to ensure smooth operation, low noise, long service life.

4 seal BURGMANN mechanical seal or packing seal. To ensure 8000 hours running without leakage.

5 installation of the installation without adjustment, according to the conditions of use. Vertical or horizontal installation.

6 installation of self suction device, can realize automatic water absorption, which does not need to install the valve, without vacuum pump, the pump can be started without backflow.

Imported double suction centrifugal pump:

Stainless steel plate pressing pump parts, laser welding, and a variety of grades of stainless steel can be used, so the double suction pump is widely used, mainly for conveying a variety of corrosive liquid light and clean water, can be used for residential water supply and the turbocharger, industrial boiler water, air conditioning system, circulation of water. And the reverse osmosis water treatment system, food industry, pharmaceutical industrial water
