From Guangzhou Zhiguang Energy Limited Ningxia aluminum assumed power plant to the pump frequency energy LIUPANSHAN renovation project successfully put into operation. This transformation is the first time following the successful transformation of Guangzhou Zhiguang Maliantai 330MW unit boiler feed pump after another major breakthrough, this transformation project uses custom-growth container replacement fluid couplings, custom tank geometry growth in three-dimensional space with fluid coupling completely accurate and consistent, equipment selection using strict German quality standards, higher than ISO5 level precision, water booster pump system conditions using the transformation reduction process, while maintaining the feed pump NPSH and ensure continuous feed pump throughout the safe operation of the feed pump motor equipped with Guangzhou Zhiguang dedicated feed pump 8000kVA intelligent high voltage inverter, which is currently in the application of thermal power plant capacity of 300MW class maximum inverter, with the fluid coupling the same adjustable speed, feedwater automatic control design new control strategy, performance is better than liquid even regulation.
Up to now, the 2nd unit A, B have been passed to the pump operating conditions ECR assessment, working properly. The boiler feed pump unit 300MW class energy-saving projects in Guangzhou Zhiguang energy company project team featuring overall design and planning, ably assisted by the cooperative unit, capturing the growth tank design and manufacture of technical problems, the front of the pump according to the project requirements transformation and use a new sealing method to further improve performance.
Over the past year, the Guangzhou Zhiguang in power plant boiler feed pump energy field continuously completed nearly 10 sets of energy-saving work to the pump, boiler feed pump comprehensive energy saving of the overall program to run after all the practice test units, Guangzhou Zhiguang's to pump technology is already reaching maturity transformation, we will continue to plant a comprehensive energy-saving industries contribute!
