Although aerators are being used more and more widely in aquaculture production, there are still some fishery practitioners who still do not understand its working principle, type and function, and are behaving blindly and arbitrarily in actual operation Sex. Here it is necessary to understand its working principle, so that in practice it will grasp its use. Xiaobian now tell you to drain irrigation pump aerator working principle, purpose and role. Irrigation and drainage pump aerator First, the irrigation and drainage pump aerator works As we all know, the purpose of using aerator is to increase dissolved oxygen to the water, which involves the oxygen solubility and dissolution rate problems. Solubility includes water temperature, water salinity, oxygen partial pressure of three factors; dissolution rate, including the degree of unsaturation of dissolved oxygen, water and gas contact area and mode, the water movement of three factors. Water temperature and water salinity is a steady state of water body, and generally can not be changed. The degree of unsaturation of dissolved oxygen is a factor that we want to change, and is also a current situation of water body. Therefore, to achieve the oxygen to the water must be directly or indirectly to change the oxygen partial pressure, water and gas contact area and mode, the water movement of three factors. In response to this situation, the design of aerator when the measures taken are: 1) the use of mechanical components agitate the body of water to promote convective exchange and interface updates; 2) the water dispersed into small droplets, spray into the gas phase, increase water and gas contact Area; 3) suction through the negative pressure, the gas dispersed into microbubbles, pressed into the water. Second, irrigation and drainage pump aerator purposes and role of Aerobic machine is a motor or diesel engine and other power sources to drive working parts, the air of the "oxygen" quickly transferred to aquaculture water equipment, which can be integrated utilization of physical, Chemical and biological functions can not only solve the problem of fish floating head caused by lack of oxygen in pond culture, but also eliminate the harmful gas, promote the convection exchange of water, improve the water quality conditions, reduce the feed coefficient and improve the fish pond activity and primary productivity. Can increase the stocking density, increase the feeding intensity of breeding objects, promote growth, so that a substantial increase in mu produce, and fully achieve the purpose of increasing farming income. Third, how to determine the type of aerator to determine the load load generally consider the water depth, area and pool shape. Rectangular pool to the best waterwheel, square or circular pond to impeller as well; impeller aerator per kilowatt power to meet the basic needs of 3.8 acres of surface pond fish oxygenation needs, 4.5 acres of fish ponds should consider the assembly Two or more aerators. Fourth, irrigation and drainage pump aerator installation position Aerator should be installed in the pond or upper position. General pool pool more than 5 m, and fixed with a plunger or anchor. Install impeller aerator should ensure that aerator in the work generated by the water will not be stirred up the bottom of the mud silt. In addition, the installation should pay attention to safety of electricity, safe use of protective measures, and often check the maintenance. Fifth, regular maintenance In order to work safely, we must regularly overhaul the aerator. Motor, gear box, impeller, float must be overhauled, the junction box has been subject to water showering and corrosion should be promptly replaced, and overhaul of the various components should be placed in a ventilated, dry place, if necessary, re-installed into the machine to use .
