Aerator safety operation method and energy-saving measures
Safe Operation Methods:
To ensure the aerator operates safely and efficiently, it's essential to follow proper safety procedures. Here are some key points to consider:
1. Always disconnect the power supply before installation. Never use the cable as a rope inside the pool. Secure the cable with a locking clip on the rack and avoid letting it fall into the water. Any remaining cables should be connected to the shore power system following electrical regulations.
2. After turning on the aerator, it may produce significant torque and must be properly fixed in place. When rotating, it can create large waves, so never stand directly in front of the aerator while using floats or other equipment.
3. If the aerator emits a "click" sound during operation, check the wiring for any missing phases. If an issue is found, immediately cut off the power, replace the fuse, and restart the unit after ensuring everything is functioning correctly.
4. Install the protective cover properly to shield the power supply from rain. The junction box is vulnerable to water damage, so make sure it is well protected against moisture exposure.
5. When starting the aerator, monitor its movement and performance. If there are unusual noises, reverse rotation, or unstable operation, stop the machine immediately. Address the issue before restarting the device.
6. Due to the harsh working conditions of aerators, users should install additional protection devices such as thermal relays, temperature relays, thermistors, and electronic protection systems to ensure long-term reliability.
7. Regularly inspect the impeller for any debris or attachments and remove them promptly. Check the buoyancy of the float annually to prevent wear that could reduce buoyancy, increase load, and potentially burn out the motor.
8. When submerging the aerator into the water, ensure it moves horizontally to prevent oil leakage from the reducer’s vent. Also, never allow the motor to come into contact with water, as this can lead to motor failure due to flooding.
9. Assign a responsible person to manage the aerator. This individual should maintain a strong safety awareness and keep detailed records of the aerator’s operation and maintenance.
Energy-Saving Measures:
Optimizing the start time of the aerator can significantly improve efficiency, reduce energy consumption, and enhance fishery productivity. Based on experience, running the aerator for 3–5 hours instead of 6–10 hours can save up to 60% of electricity, while still maintaining adequate dissolved oxygen levels for the fish.
1. Early morning, just before dawn, when oxygen levels are at their lowest after an overnight period of consumption by fish and aquatic organisms, start the aerator 1–2 hours before sunrise to restore dissolved oxygen levels to at least 4 mg/L.
2. Between 8:30 AM and 10:30 AM, when sunlight is strongest, run the aerator for 1–2 hours. This not only replenishes oxygen but also promotes water circulation and enhances the photosynthetic activity of phytoplankton, increasing dissolved oxygen naturally.
3. From 3:00 PM to 5:00 PM, when water temperatures rise, dissolved oxygen levels tend to decrease. Fish metabolism increases, leading to higher oxygen demand. Running the aerator for 1–2 hours during this time helps supply oxygen directly and stores extra oxygen for nighttime use.
In addition to these optimal timing strategies, adjust usage based on the season and weather conditions. For example, during peak fish production periods, running the aerator for 0.5–1 hour around midday can help improve water quality. On rainy days, avoid running it during the day to prevent issues like "floating head" in fish. Always stay flexible and responsive to environmental changes for best results.
