为改善风力提水机组设计中的部件匹配性问题,提高提水机组运行效率,提出一种机泵分离式风力提水机组匹配性设计方法。通过各部件运行曲线之间的工作点追踪与交叉确定风轮、空气压缩机以及隔膜泵之间相匹配的最佳设计点。并依照该方法设计试验样机,通过对样机的监测,各个运行参数之间的相关性与理论一致,样机运行稳定。该匹配性设计方法可普遍适用于机泵分离式风力提水机组,提高机组的寿命和运行效率。

In order to improve the matching problems between components in the design process of wind-driven water lifting unit and improve the operating efficiency of the unit,a matching design method of pump separation is proposed. The optimal design matching point between the wind turbine,air compressor and diaphragm pump is determined by tracing and crossing the working points between the operating curves of each component. The test prototype is designed according to the method. By monitoring the prototype,the correlations between various parameters is consistent with the theory,and the prototype runs stably. The method can be widely applied to improve the service life and operation efficiency of the Pump separated unit.
