    作者: 更新日期:2021-08-21 09:21 浏览次数: 通过对现场水泵、机组配合、管路的参数采集、计算评估,诊断出系统当前的能耗状况,通过定制高效节能泵、优化水力性能、特殊选型配置、管网优化等节能方案,让现场水泵系统处于最优性能工况点运行,从而达到高效节能效果。
    普通泵运行曲线及运行工况点A高效泵运行曲线及运行工况点CQ-H理为理论装置特性曲线,与Q-H曲线的交点H和Q为理论设计参数;
    Q-H实为实际装置特性曲线,与Q-H曲线的交点H1和Q1为实际设计参数;Q-H改为节能技术改造之后的装置特性曲线,Q-ŋ改为节能改造后泵的流量效率曲线;
    由图可以看出原水泵偏工况运行,且原泵效率低下,高效区窄,能耗大。
    经过节能技术改造后:    提高了水泵本身的机械效率,高效水泵的最高效率比原水泵的最高效率高出ŋ2-ŋ部分    提高了水泵与系统的运行效率,高效水泵的运行效率点比原水泵的实际运行效率点高出ŋ2-ŋ1部分    提高了水泵系统配置效率,见上图H1-H2差值部分

    The current energy consumption of the system is diagnosed through the parameter collection, calculation and evaluation of the on-site water pump, unit cooperation and pipeline. The on-site water pump system is operated at the optimal performance working point through customizing energy-saving pumps, optimizing hydraulic performance, special selection and configuration, pipe network optimization and other energy-saving schemes, so as to achieve the effect of high efficiency and energy saving.
    The operating curve of ordinary pump and operating condition point a, the operating curve of high-efficiency pump and operating condition point cq-h are theoretical device characteristic curves, and the intersections h and Q with Q-H curve are theoretical design parameters;
    Q-H is actually the characteristic curve of the actual device, and the intersections H1 and Q1 with the Q-H curve are the actual design parameters; Q-H is changed to the unit characteristic curve after energy-saving technical transformation, Q- ŋ Change to the flow efficiency curve of the pump after energy-saving transformation;
    It can be seen from the figure that the raw water pump operates under partial working conditions, and the efficiency of the raw water pump is low, the high efficiency area is narrow, and the energy consumption is large.
    After energy-saving technical transformation, the mechanical efficiency of the water pump itself is improved, and the maximum efficiency of the high-efficiency water pump is higher than that of the raw water pump ŋ 2- ŋ The operation efficiency of the water pump and the system is partially improved. The operation efficiency point of the high-efficiency water pump is higher than the actual operation efficiency point of the raw water pump ŋ 2- ŋ Part 1 improves the configuration efficiency of water pump system, as shown in h1-h2 difference in the above figure
