Marine centrifugal pump is an important marine equipment mainly used for transporting liquids such as fuel, lubricating oil, fresh water, etc. It has the characteristics of simple structure, easy maintenance, long service life, and high reliability, and is an indispensable part of the ship system. In this article, we will introduce the working principle, characteristics, applications, and maintenance of marine centrifugal pumps.

In order to ensure the normal operation and service life of marine centrifugal pumps, regular maintenance and upkeep are required:

Regular inspection: Regularly inspect all components of the centrifugal pump, including bearings, sealing devices, impellers, etc. During the inspection process, the equipment should be kept clean and tidy, and potential problems should be promptly identified and resolved.

Replacement of vulnerable parts: The vulnerable parts of centrifugal pumps include bearings, seals, shaft seals, etc., which should be replaced regularly according to their usage. For bearings lubricated with grease, the grease should be replaced regularly.

Cleaning and lubrication: Regularly clean and lubricate the centrifugal pump. During the cleaning process, impurities and dirt inside the equipment should be removed to maintain its good condition. Suitable lubricating oil or grease should be selected during the lubrication process, and the lubrication effect of each part of the equipment should be ensured.

Calibration performance: Regularly calibrate the performance of centrifugal pumps, including flow rate, head, efficiency, and other parameters, to ensure that the centrifugal pump operates under normal conditions and avoid overloading or low efficiency work.

Maintenance and storage: For centrifugal pumps that have not been used for a long time, appropriate maintenance and storage should be carried out, including cleaning, drying, oiling, and other operations, to maintain the good condition of the equipment. At the same time, the equipment should be stored in a dry and well ventilated place, avoiding direct sunlight and humid environments from affecting the equipment.

Safe operation: When maintaining and servicing centrifugal pumps, safety operating procedures should be followed to ensure the safety of personnel and equipment. Special safety measures should be taken for centrifugal pumps with high pressure or toxic and harmful liquids.
