Requirements for daily maintenance of centrifugal pump equipment

Requirements for daily maintenance of centrifugal pump equipment
1) Strictly follow the operating procedures to start, operate, and stop, and keep a good record of the operation.
2) Check the lubrication condition of each lubrication part of the centrifugal pump every shift.
3) After replacing the bearings, they should be cleaned and replaced with oil after 100 hours of operation. Afterwards, the grease should be replaced every 1000-1500 hours of operation, and the oil should be replaced every 2000-2400 hours of operation.
4) Regularly check the temperature of the bearings. Rolling bearings should not exceed 75 ℃, and sliding bearings should not exceed 65 ℃.
5) Regularly observe whether the pressure and motor current of the centrifugal pump are normal and stable, and whether there are any abnormal sounds or vibrations during equipment operation. If any problems are found, they should be dealt with in a timely manner.
6) Regularly maintain the cleanliness of the centrifugal pump and its surrounding environment, and promptly eliminate running, emitting, dripping, and leaking.
7) Operators and maintenance personnel should be on duty for regular inspections and promptly address any issues found.
8) When the centrifugal pump is in a low ambient temperature and the pump is stopped, drain the remaining liquid to prevent freezing and cracking of the casing and parts.
