Fish pond aerator is an indispensable fishing machine for fish farmers. Only when it is used correctly can it ensure its maximum effect.
Pay attention to electricity safety
The power supply for aerators used in fishponds is 380V three-phase electricity. Therefore, we must pay attention to electricity safety. The knife switch should be installed in a place away from rain to prevent the switch from being exposed to electricity. An aerator can be seen in the switch position so that if an abnormal condition is detected during power-up, power can be immediately switched off. The wire from the aquarium aerator to the knife switch must use the cable produced by the regular manufacturer. Generally, 31.5 cables are used.
Function and application
At present, the most widely used is the impeller type aerator, which has three functions: aeration, aeration, and adjustment of water temperature. The impeller rotates to stir the water body, and the fresh air in the atmosphere is integrated into the water to achieve the purpose of increasing oxygen. At the same time, the rotating impeller presses the upper layer of water to the lower layer, which not only transports the fresh air but also discharges the exhaust gas from the bottom of the pond. When hot, the temperature difference between the upper and lower water layers is large, and stirring the water body can make the water temperature balance.
The impeller type aerator is divided into two types: 1.5 kW and 3 kW. The 1.5-kilogram aerator can be used for fish ponds under 5 mus, and the 3-kilowatt aerator should be used for fish ponds over 5 mus, if the pond area is For more than 10 mu, one can be installed at each end of the fish pond. After the aerator is installed, the gear box should be filled with gear oil as required. After putting the aerator into the fishpond, it is necessary to check whether the impeller is balanced into the water. The impeller can be balanced by irrigating the three floats. The impeller should be submerged in water for about 1cm.
Boot mode and time
Fish farmers have experience in this area. Under normal circumstances, the fish is prone to lack of oxygen in the later half of the night. The weather is stifling, especially if the air pressure is low before the rain, it is prone to lack of oxygen. When the weather changes drastically, the oxygen-deficient pans are most likely to be used to apply the manure to the fish ponds. It is also prone to hypoxia.
Knowing the correct boot time can achieve the best effect of oxygenation. Some fish farmers have to turn on the machine when they find the head of the fish. This is incorrect. At this time, the fish have been injured due to lack of oxygen.
Therefore, after the middle of the night should be turned on for 3-4 hours or more, the weather should be turned on in time, after the fertilization also need to boot, in short, as long as there is a lack of oxygen should be promptly boot. In addition, when the weather is hot, at noon you can switch on the water for a short time to regulate the water temperature. However, it should be noted that do not turn on the power in the evening when the weather is fine, because the photosynthesis of phytoplankton in the sun can produce a lot of oxygen, and the boot will turn out the oxygen in the water.
