摘要
带行星齿轮大型潜水泵将电机的外径缩小了1/3,重量减少了60%,功率因数提高了0.2。该项技术是密封、电动机保护、齿轮技术和最新加工工艺的集成,解决了潜水泵大型化的关键技术问题。黄塘排涝站采用这种设备,并通过三维计算机模拟修改了流道的尺寸,工程投资降低了30%,为今后在低扬程地区、城市排水工程推广使用大型潜水泵提供了经验。
The large submersible pump equipped with epicyclic gear can reduce the outside diameter of its electric motor by 1/3 with the weight decrease of 60% and the power factor increase of 0. 2. The technique is an integration of hermetic sealing, electric motor protection, gear technology and the related up-to-date processing technique, which resolves the key technical problems from the large-sization of the submersible pump. After the application of this kind of pump to Huangtang Drainage Pumping Station and the improvement of the flow passage through the 3-D computer simulation concerned, the investment can be reduced by 30% and then can also provide the relevant experiences for the popularization of the application of large submersible pump to the water drainage works within the low lift regions and urban areas.
