    卧式双吸泵@桥西卧式双吸泵@卧式双吸泵110KW

    中开泵故障发生的种类有5个方面。①由于各种原因使泵的性能(流量,扬程等)达不到生产上要求。(如叶轮或管堵塞汽蚀等)②由于液体的腐蚀或机械磨损所发生的故障(如轴承磨损叶轮腐蚀等)。③填料密封或机械密封损坏而发生的故障。④其他各种机械所造成的故障(如轴承安装不当,无游隙,温升后烧坏,联轴管找中不良引起振动等)。而缩短使用周期等)。中开泵所有品种维护的重点工作是相同的。必须严格禁止在泵体中没有液体的时候,进行中开泵的运转。这也是相关工作人员在操作中开泵时经常忽略的问题。因为中开泵没有自吸的功能,启动中开泵设备之前,应该首先进行泵内是否已经充满介质的确认,通常配套管线中气体的排出,选择灌泵的方式进行。因此。

    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

    Suction tank should be easy to clean before. (4) Considering the landing of the water surface, the b of the suction pipe end should have enough submerged depth to prevent the intake from the whirlpool. (5) Before installation, to carefully check whether the bottom valve is flexible, at the same time in order to facilitate inspection and maintenance, to consider a good installation b. (6) The gate valve installed on the inlet side shall be installed in a horizontal direction or tilted downwards to avoid the accumulation of air. Import Side Gate valve In addition to inspection, switching outside, must be fully open. At the same time should try not to let the air from the sealing sleeve area. (7) The bending part is as smooth as possible, reducing the number of elbows, and should try to avoid being set close to the inlet of the pump. (8) When there is a different diameter tube, in order not to allow air to accumulate, should use eccentric type of pipe. (9) For parallel operation of the pump inlet pipe, it is advisable to use a separate water inlet pipe. If the use of direct to the common mother tube, easy to occur the imbalance of import pressure. The drive (motor) drives the impeller to rotate through the pump shaft, and the blade of the impeller drives the liquid to rotate together.

    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。

    In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.

    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。

    2.介质:温度≤105°C的清水或物理化学性质类似清水的其它液体(固体颗粒≤80mg/L)。 轴承1、采用油脂润滑的封闭式滚动轴承,维护简单,运行时间长;2、配备恒定油位的油杯,也可用稀油润滑;

    3、选用进口(SKF、NSK、NTN)高质量轴承,运行平稳,噪音低,使用寿命长。 结构 结构紧凑、稳定性好。

    S、SA系列双吸中开泵为泵壳中开结构,进出口均在泵体上,检修时只需吊出泵盖,转子部件便可移出进行检修作业,而不需拆卸管路,十分方便。 根据需要电动机(驱动机)可以在左端也可在右端,方便现场安装。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。设有泵体密封环,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。
