Outline
Aiming at the problems of packing leakage, bearing damage, shaft sleeve wear and other pump failures during slag flushing water recovery for medium plate in the water station due to a large amount of iron oxide scale in the water, an in-depth discussion was carried out. Measures including improving the material hardness of key pump components and implementing regular maintenance were proposed to reduce failures and achieve stable operation. After the application of these measures, the average annual failure rate of pumps decreased from 10.0% to 3.2%, the overall equipment effectiveness (OEE) rose from 76.2% to 89.7%, and the annual maintenance cost was reduced by 46.5%, with a payback period of 14 months for the technical renovation. This not only ensured stable and efficient operation of the equipment, but also provided certain reference value for improving the stability and service life of pumps under similar environment.
