卧式多级离心泵性能特征
Performance characteristics of horizontal multistage centrifugal pump
高强度、高质量材料以及多种选择的进、出口法兰和接管设计，提高了泵很高的许用接管载荷，高强度、高质量泵壳结构材料结构紧密使用寿命是普通铸件的5 倍，过流部位叶轮、导叶采用精密铸造，光滑平整比普通铸件效率提高2%以上。可随时满足用户特殊情况下系统的特定要求。
High strength, high-quality materials and a variety of selection of inlet and outlet flange and connecting pipe design improve the pump's very high allowable connecting pipe load. The tight service life of high-strength and high-quality pump shell structural materials is 5 times of that of ordinary castings. The impeller and guide vane at the flow passage part are made of precision casting, and the efficiency of smooth and flat casting is more than 2% higher than that of ordinary casting. It can meet the specific requirements of the system under special circumstances.
快速的装配和拆卸设计，允许水泵在不拆卸泵体和进、出口管路的情况下更换密封、轴承部件，保证了少的大修和检查时间。
The quick assembly and disassembly design allows the pump to replace the seal and bearing parts without disassembling the pump body and the inlet and outlet pipelines, ensuring less overhaul and inspection time.
高效率、高可靠性、低成本的组合。通过叶轮和导叶的最佳搭配，以及合理的配合间隙和较宽的轴向节流设计，使ZPD 型高压多级离心泵在长期运行后仍然能保持其高度的稳定性和极高的运行效率。
A combination of high efficiency, high reliability and low cost. Through the best matching of impeller and guide vane, reasonable matching clearance and wider axial throttling design, ZPD high-pressure multistage centrifugal pump can still maintain its high stability and high operating efficiency after long-term operation.
良好的汽蚀性能。采用优秀的叶轮水力模型或特殊的双吸叶轮结构，用户无需另外配置前置泵或提高进水箱的高度。
Good cavitation performance. With excellent impeller hydraulic model or special double suction impeller structure, users do not need to configure additional booster pump or improve the height of water inlet tank.
