Suction stage impeller 首级叶轮 2.Cellular surface wear rings 蜂窝状泵体密封环 3. Balancing device 平衡装置 4. Shaft sealing system 密封系统 5. Static sealing systems 唇形密封 3Barrel-type pump CHTD 1. 1st suction stage impeller首级叶轮 Optimised Suction Stage Impeller 优化的首级叶轮 More than 50,000 hours of operation without cavitation-induced wear 优异的抗汽蚀性能，运行周期可达到50,000 100,000 小时 Maximum operating periods of the suction stage impeller 首级叶轮最长的运行周期 Special vane profile for zero cavitation 特制的叶型可消除汽蚀 4Barrel-type pump CHTD Cellular Surface Wear Rings 有蜂窝窝状表面的耐磨环环 Optimized cell geometry of wear rings for: 经过优化的蜂窝形状可以使耐磨环具有下列特性: Lowest internal leakage losses 由于内部泄漏造成的损失最小 Best anti-seizure properties 防咬合性能最佳 Increased rotor stability 转子稳定性增强 Lower sensitiveness to dirt particles 对杂质颗粒的敏感性低 Long service life 使用寿命长 Lower operating costs as a result of higher efficiency 效率高、操作成本低 Higher level of operational reliabilityand availability 操作可靠性和可用性高 Your benefits 你的受益 2. Type of Wear Ring泵体密封环类型 5Barrel-type pump CHTD Double safety and reliability: When the thrust bearing fails, the double drum acts like a disc 双平衡鼓的安全可靠性: 当推力轴承损坏，双平衡鼓起到了平衡盘的作用 Lower loads on thrust bearing if the clearances increase Copes well with transient conditions (variable pressure operation) 当出现一些大负荷工况，通过轴向间隙的调节，使推 力轴承不会承受大的轴向推力 Material characteristic 平衡鼓材质同轴材质为17-4PH，平衡座套材质为 RWA350防咬合材料 Long service life thanks to improved rotor damping (large drum diameter) 长的运行寿命，高稳定性 Higher efficiency thanks to lower quantity of balancing liquid 高效率源于较小的平衡水量 KSB Solution KSB 双平衡鼓的技术优势 3. Balancing Systems双平衡鼓技术优势 6Barrel-type pump CHTD 4. Sealing systems 密封系统统浮动环密封 Highest reliability due to non-contact sealing elements 由于密封部件不接触，最长的使用寿命 Suitable for the highest system pressures, highest temperatures 适用于最高的压力和最高的温度工况 Insensitive to water chemistry 对介质的敏感性不强 p Floating seal 浮动环密封 Boiler Feed Pump 2 x 100% Cooler Sealing Condensate Tank 2x100%2x100% pe max.
