The impeller-type aerator is widely used in pond fish farming machinery. It uses agitator impellers to aerate and aerate the water, improve water quality, promote fish growth, and increase fish production. To ensure safe operation and improve the quality of work, the following points should be noted: Grass Seed,Cynodon Dactylon,Elymus Dahuricus,Onobrychis Viciifolia Chengdu Lv Mu Tian Xia Agricultural Technology Co.

1. Aerators are subject to large torque during operation and must be firmly installed. The cable should be locked on the frame with the clip clamp. Do not pull the cable. Do not pull the cable to prevent it from coming into contact with the cable.
2. The protective cover should be properly installed to prevent the electrical circuit from getting wet. At the same time pay attention to the protection of the junction box, so as to avoid leakage of water or short circuit accident caused by water splashing.
3. When the aerator is launched into the water, the unit should be moved into the water in a horizontal or near-horizontal state so that the lubricant in the reducer box does not overflow from the vent hole. At the same time, it is forbidden to contact the motor with water so as to avoid burning the motor due to flooding.
4. The installation depth of the aerator should be such that the “waterline†mark on the impeller is flush with the water surface. If there is no mark, the upper end surface should be flush with the water surface to prevent the water from entering into deep water and the motor overload and burn out.
5. When starting, pay attention to the observation of aeration machine transportation. If there is any phenomenon such as reversal, abnormal sound, vibration instability, etc., the machine should be shut down immediately, and the system can be restarted after troubleshooting.
6. Pay attention to people and animals during the operation. Do not move near the aerator impeller to avoid injury from the impeller. When found on the impeller windings or attachments should be promptly removed. It was found that when the buoyancy of the floating body is reduced, it should be checked and repaired so as not to increase the load and burn out the motor. Note: When checking and troubleshooting, stop the machine and cut off the power.
7, according to the weather changes, fish dynamics and aerobic load to flexibly master the boot, the principle is: open at noon on sunny days, cloudy early morning open, continuous rainy open at midnight, early evening not open, floating head early open, the main growth season of fish Open daily, midnight and noon hours long. During the main growth season of fish, attention should be paid to high daytime temperatures, strong sunlight, and early evening lightning strikes, or southerly winds during the day, high temperatures, sudden northerly winds at night, or excessive water feeding when the water quality is too heavy. , should pay attention to boot as soon as possible to prevent fish floating head caused "floating pond."
After the aerator has been used for a period of time, the motor, gearbox, impeller, buoy, and line, etc., are liable to be damaged and fail, and must be checked for maintenance:
1, the motor. Rotate the rotor of the motor by hand during the inspection. There is no friction sound or collision sound in the earphone. Check if the bearing is damaged, the carbon brush is worn, and the rust on the surface of the commutator is polished.
2, gear box. Check the gearbox shaft, gears and other parts of the wear, the oil seal is intact. If any damage is found, it should be repaired and replaced. If the oil in the tank has deteriorated, replace the deteriorating oil and clean the sediment in the tank and inject new oil.
3, impeller and buoy. Check whether the impeller is deformed. If it has been deformed, it should be repaired and then painted with antirust paint. Check the buoy's welding place for rust leakage. If the rust leaks, it should be repaired.
4, line. Check the insulation status of the motor with a megohmmeter, check whether the terminal is safe and secure, and whether the wire is damaged or exposed. If any of the above conditions is found, it should be repaired or replaced. Check the junction box, if it is exposed to water, it should be replaced, and make a waterproof protection of the wiring.
