【Abstract】 In the view of serious insufficiency in water supply of circulating water pumps in Pingxiang power plant, the circulating water pumps were retrofitted with the aim of increasing flow rate and saving energy. Through replacing the impeller etc key parts only, without changing motor, pump case etc, the target of raising operation efficiency and water supply amount were achieved. The retrofit featured less capital cost, quick return, and good result. Through the retrofit, the economic operation level and safety reliability of the power plant has been improved with significant economic benefit obtained.更多还原
