Precautions before installation of the pipeline in order to make the pump not due to the installation of pipes and increase excessive force, suction pipe, pressure pipe and valve class to their own support. When the takeover flange is screwed to the pump flanges, it is necessary to confirm that the flange surface is indeed tightly fastened and cannot be excessively tightened by bolts. In addition, considering the expansion of the pipeline, the subsidence of the foundation and the removal of the pump and valve, the Zui is good at using flexible joints near the pump. However, special attention should be paid to, after the pipeline is installed, the flexible joint itself must be rigid joint, so that it does not have elongation under the pressure of the phenomenon. When the pipeline should be buried in the ground, we should consider that the foundation should be adapted to uneven subsidence, freezing and so on. (1) In order to prevent air leakage, the suction pipe should be used as far as possible to use the orchid joint. (2) The layout of the suction pipe road, to try to make from the water suction to the pump has an upward slope (about 1/50) so that the tube does not accumulate air, but when the pipe submerged under the water, from the water absorption to the pump orientation of the slope. (3) The suction tank shall be provided with decontamination equipment (barrier grille).

产品概述：S、SA系列双吸中开泵，主要供输送温度不高于105°C的清水或理化性质类似于水的液体。适用于自来水厂、泵站、电站、空调循环用水、采暖用热水循环、工业供水系统、消防系统、船舶、炼油工业(一般性液体)等输送液体的场合。

产品特点：

1、内置式密封润滑结构：泵内置式密封润滑结构，密封循环水对泵密封系统的润滑、冲洗更为直接、有效。  

2、外形美观：直线型的外观并在泵盖上附加强筋，内置式密封润滑结构使泵整体结构浑然一体，灵活的结构设计使泵更加精美大方。  

3、率：采用CFD计算流体动力学，分析计算出泵内压力分布和速度分布关系、优化泵的流道设计，确保泵有的水力形线，提高了泵的效率。泵体采用双流道设计，以减小径向力。泵体、泵盖、叶轮等过流部采用树脂砂板模造型，保证了外观及流道尺寸以及泵的水力效率。S、SA系列双吸中开泵效率比一般双吸泵高3～5％。  

4、平衡精度高：转子部件动平衡精度为G1。0级。  

5、轴：轴短且刚性好，增加轴径，以延长轴承和机械密封的使用寿命。轴为全封结构，确保了不与介质接触，不锈蚀，使用寿命长。  

6、双蜗壳：高扬程泵采用双蜗壳结构，减轻了径向力。

Pipeline installation should try to overcome the phenomenon of too much elbow, the elbow radius of the pipe should be larger. (3) Check whether the packing seal leaks too much or too little, especially the inlet pipe. Pipe length should not be too long. (2) When using bending pipe, the straight pipe part before and after the pump import and export should be at least 5~10 times the diameter of the pipe. (3) In order to prevent the reversal of parking, water hammer phenomenon, in the pump pressure out pipe should be equipped with a check valve, in order to adjust the flow, in the pump pressure out of the pipe should be equipped with a gate valve; the check valve is installed between the pump and the gate valve. (4) After the piping is installed, further check the neutral of the pump and motor couplings. (5) Install all pipes, such as water seal pipe parts, cooling pipe parts, etc. Each pipe should be smooth, sealing should be strict. (6) The pressure gauge joint parts are installed in the pump inlet and outlet flange all the open pump is left with the installation pressure gauge screw hole, screwed down for the pressure gauge joint parts of the wire plugging, according to the technical inbation provided by the pump factory, select the appropriate pressure gauge and vacuum meter installed in the pump outlet and import respectively.

工作条件：

1．许用工作压力为2.5MPa；即泵入口压力+泵扬程≤2.5MPa。根据泵壳承受的压力，泵体和泵盖材质采用灰口铸铁(1.6MPa)、球墨铸铁(2.0MPa)、铸钢(2.5MPa)。在订货时敬请注明泵的承压情况或材质。
