Description

technical field [0001] The invention belongs to the technical field of state monitoring of electromechanical equipment, relates to an online monitoring test platform for water-lubricated bearings, and also relates to a test and analysis method for bearing characteristics. Background technique [0002] As an important component of underwater power machinery, water-lubricated bearings have a wide range of sources because their lubricants are directly obtained from water. What is important is that compared with oil-lubricated bearings, they will not pollute the environment due to grease leakage, and do not require complicated The lubricant supply system simplifies the mechanical structure, greatly improves the operational reliability, stable performance, and safe use. Therefore, it has been more and more widely studied and used in recent years. [0003] Water-lubricated bearings use water as a lubricant. Under certain conditions, a water film will form between the bearing and t...
