What Are The Maintenance And Maintenance Methods Of Marine Three-Phase Asynchronous Motor?
Regular cleaning: The motor should be cleaned regularly to keep the outside of the motor clean and reduce the accumulation of dust. Use compressed air or a soft cloth for cleaning.
Maintenance lubrication: The motor needs to be lubricated according to the specified lubrication cycle or working time to ensure the smooth operation of the shaft and bearing.
Check the motor thermal protector: If the motor has a thermal protector, it is necessary to regularly check whether its function is normal.
Check the insulation system: The insulation system of the three-phase asynchronous motor needs to be checked regularly to check whether the insulation performance is normal and to prevent moisture or aging.
Check the electronic control system: It is necessary to check the electronic control system regularly to ensure the normal function of the controller and protector.
Check the wiring and junction box: You need to check the motor wiring and junction box to ensure that the wiring is correct, and there will be no loose or bad wiring problems.
Regular check of mechanical parameters: it is necessary to measure parameters such as speed, load and current regularly to ensure noise reduction and efficient operation of the motor.
Preparation before deactivating the motor: Before deactivating the motor, the power supply needs to be cut off first, and it is necessary to ensure that the motor has stopped rotating. Otherwise, it will affect the motor and affect the life of the motor.
Environmental control: Ensure that the use of the motor environment is dry, and maintain the clean surface of the motor, do not let dust, fiber to hinder the air intake. When the motor is continuously protected by heat, the source of the fault should be checked to make it clear whether it is the cause of the motor itself or the setting value of the protection device is too low or the bearing overload, and the motor can work after the fault is eliminated.
Bearing inspection and replacement: the lubrication of the bearing should be checked to ensure that the lubricating oil or fat is sufficient. Change the lubricant regularly as recommended by the manufacturer. If the bearing has reached the end of its life, it will be found that the noise and vibration will be significantly larger when the motor is running, and the bearing should be replaced when the radial clearance of the bearing is checked for a certain value.
Marine motor is one of the important parts of ship operation, in order to work more safely and efficiently, Marine efficient three-phase asynchronous motor is the need for regular maintenance, maintenance and inspection.

Screw inspection and fastening: The screws of the motor junction board should be checked frequently to see if they are loose, and if the screws are loose, they should be tightened again and repaired with the same insulation wrap.
