The maintenance of a floating aerator should be based on its structural characteristics and operating environment. The following are the key maintenance points:
1、 Daily maintenance
1. Appearance and sealing inspection
Check daily whether the connecting bolts, cable interfaces, and aeration pipelines of the float are tightened to prevent water seepage or loosening.
Observe the levelness of the float, and the deviation angle should be less than 5 ° to avoid uneven force on the equipment due to tilting.
2. Electrical safety testing
Measure the insulation resistance of the motor every month to ensure it is not less than 1M Ω and prevent the risk of leakage.
2、 Regular deep maintenance
1. Cleaning of impellers and diffusion devices
Clean the attachments (such as algae and fibers) on the impeller every quarter to avoid blockages that may affect aeration efficiency.
Check if the aeration head or diffusion tube is blocked, and if necessary, rinse with a high-pressure water gun.
2. Lubrication and mechanical component inspection
Replace the bearing grease annually, with a filling amount of 70% of the bearing chamber volume.
Check the wear of the mechanical seal and replace it promptly if there is a leak.
3、 Fault prevention and operation taboos
1. Confirmation before startup
Before powering on, it is necessary to verify that the impeller direction is consistent with the markings, as reverse rotation can damage the equipment.
Do not start when there is no gas supply pressure or insufficient lubrication to avoid dry friction of the bearings.
2. Environmental adaptability maintenance
When used in water bodies containing corrosive media for a long time, it is necessary to shorten the inspection cycle and focus on protecting metal components.
4、 Seasonal maintenance recommendations
1. Winter antifreeze: When not in use, drain the accumulated water in the pipeline to avoid freezing and cracking.
2. Summer heat dissipation: Check the temperature rise of the motor, ensure good ventilation, and prevent overheating.
The above measures can significantly extend the lifespan of equipment and maintain efficient operation.
