方便现场安装。(1)结构上缩短转子部件轴向尺寸，轴的钢性更好，运行更稳定可靠。设有泵体字符封环，而叶轮密封环为可选用件。密封环磨损后可以更换，减少了运行维护费用。S系列中开泵装配与拆卸1，装配转子部件：依次将叶轮，轴套，轴套螺母，填料套，填料环，填料压盖，挡水圈，轴承部件装在泵轴上，并套上双吸密封环，然后装上联轴器。将转子部件装在泵体上，调整叶轮的轴向位暈到两侧双吸密封环的中间加以固定，将轴承体压盖同固定螺钉紧固。装上填料，放好中开面纸垫，盖上泵盖打紧螺尾柱销后，拧紧泵盖螺母，zui后装上墳料压盖。但不要将填料压得太紧，填料过紧会使轴套发热，耗费功率较大，也不要压得太松，过松会使液体渗漏大，水泵效率降低。

运行数据：出口直径：DN=80～800mm流量：50～11600m3/h(额定点)扬程：H＝7.6～200m(额定点)许用工作压力：≤2.5MPa许用试验压力：≤3.75MPa介质：清水或物理化学性质类似于清水的其它液体(固体颗粒≤80mg/L)。温度：≤105°C水力经优化设计三水力模型，不仅使泵具有优异的水力性能，并且没有轴向力(理论上)这一困扰水泵特别是大型水泵运行的难题。泵体、泵盖、叶轮经精密铸造，过流表面光滑提高了泵的抗汽蚀性能和效率。密封根据输送介质或用户要求采用填料密封或机械密封，不受转向限制。对于填料密封，有足够的空间用于更换填料。jdhuiquan4.13

In order to achieve the purpose of sealing, while the dynamic ring and static ring has a lubrication effect. The medium-open pump is regularly inspected during operation. The characteristics of the use of mechanical seals in medium-open pumps 1, the main advantage of the mechanical seal of the medium open pump is that the seal is reliable in a long life cycle, the leakage is very few, the effect is long, generally can use about 5 years, the maintenance cycle is long. However, the mechanical seal structure is complex, the manufacturing and installation precision is high, the lattice is high, the technical request to the maintenance personnel is high. Therefore, it is very important to ensure the reliable operation of mechanical seals and extend the service life of mechanical seals. Of course, the price sealed with seasoning is cheap, the technical requirements are relatively low. The problem that the mechanical seal of medium open pump is easy to occur in the process of use, the main problem that the mechanical seal is easy to occur is the leakage amount is very poor and the temperature is too high. Touch the mechanical seal cover with your hand, and if you can't stay on it, it means the temperature is too high. Leakage per side should not exceed 60 drops of/min, if linear flow, it indicates that the amount of leakage is too large, can determine whether to observe the operation;

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。

To bring it into line with the principles of economy, safety and application. The reliable operation of the medium-open pump determines the normal operation of the industrial production system, we can also assist in the operation of the pump in a series of things. In the operation of the medium-open pump by performance differentiation into three data, small flow and high lift, medium flow and medium lift, large flow and large lift. It should be noted that in these three kinds of performance, to avoid the pump long-term operation under small flow and large lift, so that the pump will produce a vortex, vortex will produce a large thrust, so that the shaft bending deflection is too large, not conducive to continuous operation. In the rotating component lubrication efforts, the rotary components of the pump have bearings, shafts and other forms, to ensure their lubrication, regular inspection of lubricants, check the amount of oil, oil can not be too little, not too much, oil quality is also very important, when the oil spoilage to be replaced in a timely manner. The pump group for planning management, the operation of the pump and maintenance of the installation rules and regulations, so that the temperature is not exceeded, the speed of operation is not speeding.
