Abstract

Abstract: The problems, which are caused by improper design and selection of the closedcycle cooling water pump of the 670MW unit in Huadian Weifang Power Generation Company Limited, were analyzed. The design parameters of the pump were modified. The entire flow pass of the impeller was optimized. The impeller was reformed by special cutting method. So the safety margin of the pump became more reasonable, and the economical efficiency of the unit operation was improved.

Key words: energy-saving reformation, closed-cycle cooling water pump, impeller, spiral casing, optimization
