The operation and maintenance of centrifugal pumps also need to pay attention to the following points:
First of all, for the newly installed centrifugal pump, a period of running-in operation should be carried out at the beginning of operation to check the operation status of the pump and the running-in of the bearings. During this time, close attention should be paid to parameters such as bearing temperature, vibration and noise to ensure that the pump is operating at its best.
Secondly, during the operation of the centrifugal pump, the lubricating oil should be changed regularly to ensure the normal lubrication of the bearing. At the same time, attention should be paid to check the oil level and oil quality to ensure that the oil quality is clean and free of impurities.
In addition, during the operation of the centrifugal pump, it should be avoided to run overload for a long time to avoid damage to the pump body and bearings. When it is found that the pump body temperature is too high, the vibration is too loud or the noise is abnormal, it should be stopped immediately for inspection, find out the cause and deal with it.
Finally, for centrifugal pumps that have been out of service for a long time, cranking operations should be carried out regularly to prevent the bearings from rusting and seizing. At the same time, the integrity of the pump body and bearings should be checked before starting to ensure that the pump can be started and operated normally.
In short, the operation and maintenance of centrifugal pumps need to consider many aspects, including the inspection of bearings, pump bodies and accessories, sealing devices, inlet and outlet pipelines, and electrical and electrical equipment. Only comprehensive and meticulous inspection and maintenance can ensure the long-term stable and efficient operation of centrifugal pumps.
