The aeration aerator drives the working parts through a power source such as an electric motor or a diesel engine, and quickly transfers the "oxygen" in the air to the aquaculture waters. Comprehensive utilization of physical, chemical and biological functions can not only solve the problem of fish docks caused by insufficient oxygen in pond culture, but also eliminate harmful gases, promote water bodies, increase stocking density, increase the intake intensity of cultured objects, promote growth, and greatly improve sugar-free output, and fully achieve the purpose of increasing the income of aquaculture.
What is the working principle of aerators?
The application of aeration aerators in aquaculture production is increasingly widespread, but at present, some fishermen do not understand its working principle, type and function, and there are blindness and randomness in actual operation. It is said that the purpose of using an oxygen booster is to increase the dissolved oxygen in water, including the solubility and solubility of oxygen. The contact area and contact method of the gas and the motion state of the water, the water temperature and the salt content are stable, and the unsaturation of dissolved oxygen is a factor that we must change, and it is also the status quo of the water. Therefore, in order to increase the production of oxygen in the water, it is necessary to Directly or indirectly alters the partial pressure of oxygen, the way it contacts the area with water, and the state of water movement.
1) The mechanical part is used in mixed waters to facilitate convective exchange and interface renewal.
2) The water is dispersed in the air phase in the form of small droplets, increasing the contact area at one time.
3) The gas is dispersed in microbubbles and sucked into the water under negative pressure.
When the fishery is deficient in oxygen, the aeration aerator machine can be activated, and the air can prevent the fish and shrimp from floating. On a sunny day, the upper oxygen level is high, which is conducive to accelerating the convection of the water, increasing the dissolved oxygen in the lower water, and reducing the rapid growth of fish and shrimp. , food coefficient, promote the oxidative decomposition of organic matter and reduce the occurrence of diseases; in addition, the water cycle promotes the reproduction of plankton and improves the primary productivity of the pond.
