The model of the aeration vortex air pump in the fishpond shall match the water depth and area of the pond, but the water depth shall be mainly considered. 3 kW oxygen increasing gas pump is suitable for 1.4-2.0 m water depth, 5.5 kW oxygen increasing gas pump is suitable for 2.0-4.0 m water depth; If the impeller type aerator is used in the water depth below 1.3m, the sludge at the bottom of the pool will rise, which will lead to the increase of biochemical oxygen consumption, but will reduce the dissolved oxygen in the pool.
Therefore, in general, it is appropriate to configure a water jet aerator for ponds with water depth less than 1.3 meters. To increase the spray area or directly fill the water with oxygen.
*For ponds with an output of 500-800kg per mu, it is advisable to equip a 3kW oxygen increasing gas pump on the water surface of 3-5 mu
*For ponds with an output of 800-1500 kg per mu, it is advisable to equip a 5.5 kW oxygen increasing gas pump on 5-8 mu of water surface; It can also do 3-5 m deep water aeration according to customer requirements.

use:
When the machine is started at noon on a sunny day, the temperature difference between the upper and lower water layers in the fishpond is large and the convection is small, so the oxygen in the lower water body is often not replenished in time. When the aerator is started, the resistance of water can be broken, so that the upper and lower water bodies can be exchanged. The temperature difference and oxygen difference will also be greatly reduced, and the oxygen in the lower water body can be replenished in time.
When the machine is started in the morning on a cloudy day, the sunlight intensity is weak, the photosynthesis of phytoplankton in the fish pond produces less oxygen, and the dissolved oxygen in the whole water body is poor. Starting the aerator in the early morning when the dissolved oxygen point is low can prevent fish from "floating head" due to lack of oxygen in the water before and after dawn.
Power on in the middle of the night on rainy days Under the condition of continuous rainy weather, due to the lack of sunshine for a long time, there is little oxygen produced by photosynthesis of phytoplankton in the fish pond, so the power on must be started in the middle of the night to increase oxygen, so as to prevent the death of fish flooding the pond.
When the sun goes down when the machine is not turned on in the evening, the photosynthesis of phytoplankton in the fish pond will also stop, and oxygen can no longer be supplied to the water. If the machine is started at this time, the dissolved oxygen in the upper water body will be reduced and can not be supplemented, and the dissolved oxygen in the lower water body will be consumed quickly, which will speed up the oxygen consumption, and the fish "floating head" phenomenon will be more likely to occur in the morning of the next day.
In addition, the time to start the aerator is also very particular: the time to start the aerator is long in muggy weather and short in cool weather; The startup time should be long at midnight and short at noon; The start-up time should be longer after fertilization, and shorter when no fertilization is applied; The startup time should be longer when the wind is hour, and shorter when the wind is strong.
Maintenance of oxygen increasing fan:
(1) The motor of the oxygen charging high-pressure blower in the fishpond is directly connected to the impeller and is of high speed. The bearing needs to be added with grease for regular maintenance to prevent damage (including the bearing of the impeller).
(2) The shaft power of the motor is proportional to the pressure. In order to prevent the long-term limit pressure of the fishpond oxygen charging high-pressure blower from increasing the shaft power and overloading the motor, the pressure relief valve is often used. It is a unloading valve. When the operating pressure of the fishpond oxygen charging high-pressure blower exceeds the pressure set by the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure, So as to protect the motor of the oxygen charging high-pressure blower in the fishpond.
(3) The internal mechanism of the fishpond oxygen charging high-pressure blower is relatively tight, and the clearance between the impeller and the casing is very small, so it is necessary to filter debris and dust. For sundries, a fine filter screen is usually installed at the air inlet. For dust, a filter is often used. It often uses filter elements with different filtering precision according to different use sites. Different filter elements have different maintenance methods and service life, so it is necessary to ask clearly when ordering.
(4) In some special occasions, it is also necessary to provide special protection for the oxygen charging high-pressure blower in the fishpond: for example, when using in a sealed environment, pay attention to ventilation and heat dissipation; When the ambient temperature (when the inlet air temperature is relatively high), pay more attention to ventilation and heat dissipation, or select the oxygen charging high-pressure blower in the fishpond that allows higher inlet air temperature.
