森兰690V 850kW变频器在隔膜泵上的应用

Application of SenLan 690V 850kW Frequency Converter on Diaphragm Pump

隔膜泵是一种新型的特殊流体输送机械，也是目前国内最新颖的一种泵类。近年来，采用森兰研制的SB70G850kW（690V）矢量控制变频器，取代了引进的国外变频器对隔模泵的控制。投运近一年以来，运行实践表明，其性能和可靠性完全满足氧化铝生产工艺的要求，隔膜泵变频器的国产化是必要且可行的。

Diaphragm pump is the newest type of special liquid transportation machine in China. In recent years, SenLan SB70G850kW （690V） vector control frequency converter has been adopted in the diaphragm pump to replace the imported frequency converter that was used to control the diaphragm pump. After one-year operation, it is proved that the performance and reliability can satisfactorily meet the technical requirements of the alumina production technology. And its performance and reliability fully meet the production process requirement. Therefore, the localization of the inverter for diaphragm pumps is necessary and feasible.
