Fish pond, shrimp pond, crab pond aerator pump

Fish pond, shrimp pond, crab pond aerator pumpIt is a new type of power gas source equipment suitable for aeration and oxygenation in aquaculture, with stable pressure, safety and reliability, and long service life; The appearance of the aerator fan is beautiful, the operation is balanced, and it is easy to use. The fan blades are made of high-strength aluminum alloy; Equipped with dual functions of blowing and suction, this machine can be used for both suction and blowing purposesCompared to other fans, its pressure is much higher, often more than ten times that of ordinary fans in terms of dynamic pressure and negative pressure.
Fish pond oxygenation pumpIt is a type of mechanical equipment commonly used in fisheries and animal husbandryIts main function is to increase the oxygen content in the water to ensure that fish in the water do not lack oxygen, while also inhibiting the growth of anaerobic bacteria in the water and preventing the deterioration of the pool water from threatening the living environment of fish. An aerator usually relies on its built-in air pump to pump air into water. Reasonable use of aerators can not only prevent and reduce floating heads, but also improve water quality, enhance pond water circulation, promote plankton reproduction, and thus improve the economic benefits of aquaculture.
Aquaculture oxygen supply fanThe working principle of the device is to send air into a gas pipeline. The gas pipeline sends air into a microporous aeration tube or other aeration device. Due to its small pore size, it can generate a large number of fine bubbles that emerge from the pipe wall and disperse into the water. Moreover, the rising speed is slow, and the bubbles move slowly in the water, with a long stroke and sufficient contact with the water body. The gas-liquid phase oxygen molecule exchange is sufficient, and the rotation and up and down flow of the water flow are also increased. The up and down flow of water brings oxygen rich water from the upper layer into the bottom layer, while the rotating flow of water spreads oxygen rich water around the microporous tube outward to achieve uniform oxygenation of the aquaculture pond water.

Working principle of oxygen supply fan for aquaculture

After the power is turned on, the fan rotates. Due to the groove design of the impeller, it will drive air flow. Therefore, air enters the pump body through the inlet, and the air is stirred inside. Each groove is pressurized by a vortex, and a powerful airflow energy is formed through a cycle of pressurization. It is discharged from the pump body through the outlet for use.

The fan blades that generate centrifugal force are made of double-sided forward leaning multi blade, molded in one go, with high-quality dynamic balance by computer, extremely low vibration, stable wind force, low noise, and can withstand certain frictional impact force, with a long service life; 7. The drainage side panel has a built-in side suction port, which, when combined with the fan blades, can generate a large negative pressure suction force, making the self-priming feeding more stable.

Analysis of the necessity of using oxygen supply fans in aquaculture

Research has shown that when the oxygen content in pool water is above 3mg/L, fish are more likely to live normally; When the oxygen content in the pool water is around 2mg/L, it affects the normal life of some fish; If the oxygen content in the pool water is below 1mg/L, many fish species will feel difficulty breathing, almost stop feeding, and exhibit floating head phenomenon. If the oxygen content in the water continues to decrease, it will cause the fish to suffocate and die. So generally, 3mg/L is used as the safe concentration of oxygen content in pool water, 2mg/L is used as the warning concentration, and 1mg/L is used as the dangerous concentration. Meanwhile, practice has proven that the food intake of fish is directly related to the oxygen content of water. When the oxygen content in pond water is high, the food intake of fish increases, and the two are directly proportional. When the feed ingredients are the same, raising fish in oxygen rich water can make more efficient use of the feed and promote faster fish growth. So dissolved oxygen in water is a very important factor in regulating fish growth. Under certain external conditions such as air pressure and temperature, the saturation solubility of oxygen in water is constant. At a certain pressure, the lower the temperature, the higher the saturation solubility of oxygen, and the higher the temperature, the lower the saturation solubility of oxygen. At a certain temperature, as the air pressure decreases, the saturation solubility of oxygen decreases, and as the air pressure increases, the saturation solubility of oxygen increases. So under natural conditions, the sources of dissolved oxygen in fish ponds mainly come from two aspects: one is the photosynthesis of algae and phytoplankton in the water, which accounts for about 90% of the total dissolved oxygen in the water, and the other is the diffusion of oxygen molecules from the atmosphere to the water surface. Research has shown that under conditions of sufficient dissolved oxygen content in water, a fish pond with a depth of about 2 meters per acre can only supply 250-300kg of fish for consumption. Therefore, it indicates that traditional fish pond farming techniques cannot significantly increase fish yield under natural conditions. Therefore, in order to increase the yield of fish farming in ponds, it is necessary to adopt artificial methods to oxygenate the water to increase the oxygen content. To achieve the goal, a high-pressure blower is an essential air source tool.

Selection and usage precautions of oxygen supply fan for aquaculture

1. How to determine the type: Determining the loading load generally considers water depth, area, and pool shape. Square or circular pools are better with impeller type; The blade type aerator can basically meet the oxygenation needs of 3.8 acres of adult fish ponds per kilowatt of power. Fish ponds over 4.5 acres should consider installing two or more aerators. 2. Installation location: The aquaculture aerator fan should be installed in the center or upwind position of the pond. Generally, the distance from the pond embankment is more than 5 meters, and it is fixed by inserting poles or anchoring. When installing the impeller aerator, it should be ensured that the water flow generated by the aerator during operation will not stir up the sludge at the bottom of the pool. In addition, attention should be paid to safe use of electricity during installation, protective measures should be taken for safe use, and regular inspections and repairs should be carried out. 3. Startup and running time: The aquaculture aerator fan must operate safely, and the running time should be determined based on factors such as the stocking density of fish in the pond, the growing season, the water quality conditions of the pond, weather changes, and the working principle, main function, aerating performance, and aerator load of the aerator, so as to be effective without waste. To correctly control the startup time, it is necessary to achieve "six on and three off". That is, "six on": 1) Turn on the device in the afternoon on a sunny day; 2) On cloudy days, turn on the machine the next morning; 3) Turn on the machine in the middle of the night during continuous rainy weather; 4) Start up in the first half of the night in case of rainstorm; 5) Start up promptly when there is a large temperature difference; 6) Power on at any time under special circumstances. Three no's ": 1) Do not turn on after sunrise in the morning; 2) Not turning on in the evening; 3) On rainy days, the device does not turn on during the day. In addition, when there is a sudden change in weather or when there are too many fish floating due to water and fertilizer, the startup time can be flexibly controlled to prevent floating or flooding. 4. Regular maintenance: In order to ensure safe operation, it is necessary to regularly inspect the aerator. The electric motor, gearbox, impeller, and float all need to be inspected. For junction boxes that have been corroded by water, they should be replaced in a timely manner. At the same time, the inspected components should be placed in a ventilated and dry place, and if necessary, they should be installed as a complete machine for use.
