进口双吸离心泵概述：
双吸泵的吸入口与吐出口均在水泵轴心线的下方，与轴线垂直成水平方向。检修时无需拆卸进出口水管及电动机。从传动方向看去，水泵为顺时针方向旋转（根据用户需要亦可改为逆时针方向旋转）。
﹒泵的主要零件有；泵体、泵盖、叶轮、轴、双吸密封环、轴套等。除轴的材料为优质碳钢外，其余主零件由铸铁、铸钢、不锈钢制成。
﹒泵体与泵盖构成叶轮的工作室，在进出法兰上，装有安装真空表和压力表的管螺孔。进出水法兰的下部，装有放水的管螺纹孔。
﹒经过静平衡检验的叶轮，用轴套和两边的轴套螺母固定在轴上，其轴向位置可通过轴套螺母进行调整。叶轮的轴向力利用其叶片对称布置、两面进水达到平衡。
﹒泵轴承为向心球轴承。轴承装在轴承体内、安装在泵体两端，用黄油润滑。
﹒双吸密封环用以减少水泵压力室的水漏回吸水室。
﹒泵通过弹性联轴器由电动机直接传动，必要时亦可用内燃机传动。
﹒轴封为软填料密封（根据需要也可装机密封）。为了防止空气进入泵内和冷却润滑密封腔，在填料之间装填料环，水泵工作时少量高压水，通过泵盖中开面上的梯形凹槽流入填料腔，起水封作用。
进口双吸离心泵结构特点
1. 结构紧凑 外形美观，稳定性好，便于安装。
2. 运行平稳 优化设计的双吸叶轮使轴向力减小到zui低限度，且有优异水力性能的叶型，并经精密铸造，泵壳内表面及叶轮表面极其光华具有显著的抗汽蚀性能和高效率。
3. 轴 承 选用轴承保证运行平稳，噪音低，使用寿命长。
4. 轴 封 选用BURGMANN机械密封或填料密封。能保证8000小时运行无泄漏。
5. 安装形式 装配时不需调整，可根据现场使用条件。分立式或卧式安装。
6. 加装自吸装置，可实现自动吸水，即不需安装底阀，不需真空泵，不需倒灌，泵可以启动。
进口双吸离心泵应用范围：
泵的零件用不锈钢板压制，经激光焊接而成，并有多种牌号的不锈钢可供选用，因而双吸泵的用途十分广泛，主要适用于输送各种洁净水及轻腐蚀液体，可用于住宅供水及增压,工业锅炉给水,空调系统,循环体会水,水处理和反渗透系统,食品工业,医药工业用水

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
