8 acres of water surface adult fish ponds, and fish ponds above 4. Rectangular ponds are of waterwheel type, square or round ponds are of impeller type; each kilowatt of impeller type aerator can basically meet the aeration needs of 3. For ponds without aeration facilities, some aerators should be equipped to prevent emergency use. Generally, the distance from the embankment is more than 5m, and it is fixed with a plunger or anchor.Reasonable use of aerators can effectively increase the amount of dissolved oxygen in the pond water, accelerate the circulation of pond water bodies, eliminate harmful substances, and promote the reproduction of plankton . Minimize operating costs and save expenses. . I sincerely hope to cooperate with all friends, join hands in the future, and share successful results. Motors, gearboxes, impellers, and floats should be overhauled.How to determine the type: The water depth, area and pool shape are generally considered to determine the loading load. The principle of selection of aerators is to fully meet the needs of dissolved oxygen for normal fish growth, effectively prevent hypoxic dead fish and deterioration of water quality, reduce feed utilization and fish growth speed, and cause fish diseases to occur. Installation location: The aerator should be installed in the middle of the pond or at a windward position. The junction boxes that have been eroded by water should be replaced in time. In addition, pay attention to the safe use of electricity during installation, take protective measures for safe use, and frequently check and repair. The principle of opening at noon on a sunny day, early morning on a cloudy day, continuous rainy day at midnight, no opening in the evening, and early opening of the floating head; the operating time should be determined according to the weather, water quality, the condition of the floating head of the fish and shrimp, and the load area of \u200b\u200bthe aerator.5 acres should be equipped with two More than one aerator. At the same time, it can prevent and reduce fish floating heads, prevent flooding, improve pond water quality, increase fish food intake and increase unit area yield. will tell you some problems that should be paid attention to when using aerators.At the same time, all parts after overhaul should farm aerator be placed in a ventilated and dry place, and they should be installed as a complete machine when needed. The use of the aerator should be based on the law of dissolved oxygen changes in the water and the role of the aerator to scientifically determine the startup time and the operating time of the machine. Start-up and running time: aquatic product aerator must be operated under safe conditions, combined with the stocking density of fish in the pond, growing season, pond water quality conditions, weather changes, working principle and main functions of the aerator , Aeration performance, aerator load and other factors to determine the running time, so that it works without waste. When installing the impeller aerator, ensure that the water flow generated by the aerator during operation will not stir up the silt at the bottom of the pool. So here are some points to pay attention to when using aquatic aerators correctly. Regular maintenance: For safe operation, the aerator must be regularly checked and repaired. Therefore, the selection of aquatic aerators should be based on comprehensive considerations such as the depth of the pond, different fish pond areas, aquaculture yields, aerator efficiency and operating costs.The length.\ufeffIn today's scientific fish farming, many fish farmers use aquatic aerators lack of scientificity, which directly affects the use of aerators.
