Analysis of The Transformation and Replacement of Centrifugal Pump of The Main Transformer Technology Water Supply System of a Giant Hydropower Station
Main Article Content
Abstract
Since the giant power station was put into operation, the centrifugal pump of the main transformer technology water supply system often has defects such as bearing oil tank oil leakage, large packing leakage, abnormal bearing noise, large vibration, motor bearing temperature rise, motor winding lead wire burning, etc., which affect the safe and stable operation of the equipment. In order to effectively solve the problems that often occur during the operation of the centrifugal pump, it was decided to carry out experimental modification of the centrifugal pump. In this paper, the centrifugal pumps before and after the transformation are compared, and the operating effect of the centrifugal pump after the transformation is analyzed. Through tests and long-term operation observations, it is shown that the experimental transformation of the main transformer centrifugal pump in the power station is scientific and reasonable, which provides a reference for the transformation and upgrading of centrifugal pumps in the industry.
