| Abstract: | A large scale split casing centrifugal pump was improved through frequency control using the modern control technology, frequency control technology and centrifugal pump theory and the application of frequency control on pump was extended further. The rotation speed control characteristics of the large scale centrifugal pump were theoretically analysed and the design of the control system and setup of the giant power transducer were described. Besides that, industry applications of the newly developed frequency control on large scale split casing centrifugal pump were described. The applications of the new type centrifugal pump showed a substantial energy saving effect in water supply system, and it improved the control performance and operating reliability of the water supply system. |
