Planned maintenance management for high-pressure ash water pumps
Thread Content
Please share how your respective organizations plan the inspection, maintenance, and management of high-pressure ash water pumps.
During routine maintenance inspections, pay attention to any faults that may be detected; identify them as soon as possible to prevent the situation from worsening. This includes monitoring the pump’s pressure, temperature, oil temperature and level, noise levels, current, flow rate, and vibration. There is also the need to control the temperature of the deaerator to prevent pump cavitation, and to control the pressure in the deaerator to stop the packing from the tower plates from entering the inlet filter. I’m not very familiar with the maintenance procedures, but it’s essential to clean the fouling in both the inlet filter and the deaerator. It’s also necessary to check whether the backup inlet manual valve can be closed properly to prevent the inlet filter from getting clogged
