轴承间距较短,从而减小了轴的挠度,延长了机械密封和轴承的寿命。轴套可以采用多种不同的材料,以防止轴被腐蚀和磨损,轴套可更换。磨损环泵体与叶轮间采用可更换的磨损环,防止泵体和叶轮的磨损,更换方便,维修费用低,同时保证运行间隙和较高的工作效率。
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。jdhuiquan7.17

双作用水环泵比单作用水环泵大大减少尺寸和重量。由于工作腔对称分布于泵轮毂两侧,改善了作用在转子上的载荷。此种泵的抽速较大,效率也较高,但极限真空较低(3)双级水环泵:双级水环泵大多是单作用泵串联而成。实质上是两个单级单作用的水环泵的叶轮共用一根心轴联接而成。
工作条件:1. The allowable working pressure is 2.5MPa, that is, the pump inlet pressure + pump lift ≤2.5MPa. According to the maximum pressure under the pump shell, the pump body and pump cover material using gray cast iron (1.6MPa), Ductile iron (2.0MPa), cast steel (2.5MPa). Please indicate the pressure of the pump or the material at the time of ordering.
2. Media: Water with a temperature of ≤105°C or other liquids of physicochemical properties similar to water (solid particles ≤80mg/L). Bearing 1, the use of grease lubrication of closed rolling bearings, simple maintenance, long running time, 2, equipped with a constant oil level oil cup, can also be used dilute oil lubrication;
3, the selection of imported (SKF, NSK, NTN) high-quality bearings, smooth operation, low noise, long service life. Compact structure and good stability.
S, SA series double suction medium open pump for the pump shell open structure, import and export are in the pump body, maintenance only need to hoist the pump cover, rotor parts can be removed for maintenance operations, without the need to disassemble the pipeline, very convenient. According to the need of electric motor (drive) can also be on the left side at the right end, convenient for on-site installation. The structure shortens the axial size of the rotor parts, the steel of the shaft is better, and the operation is more stable and reliable. Equipped with pump body seal ring, and impeller seal ring for optional parts. The sealing ring can be replaced after wear, reducing operating and maintenance costs.

双吸泵的抗气蚀能力比单吸泵要强由于介质在叶轮两端,会形成水力对称这样双吸泵的平衡轴向推力作用比单吸泵要好,运行起来更平稳而且介质的流速较低,叶轮不容易产生气蚀现象。但是双吸泵比单吸泵要多一个密封腔,所以其成本相对较高,其次,输送流量要求不同双吸泵更适合输送大流量。
