Fish and shrimp oxygen pump

Fish and shrimp aeration pump

Fish and shrimp oxygenation pump is an important equipment for aquaculture fish pond water oxygenation, is to use the high pressure of high pressure fan, large air volume forced into the water, so that the oxygen in the air dissolved into the water, increase the oxygen content of the water; its main function is to increase the dissolved oxygen in the water, to ensure that the fish in the water will not lack oxygen, at the same time, it can inhibit the growth of anaerobic bacteria in the water, prevent the deterioration of anaerobic bacteria in the water and threaten the living environment of fish; The fan has the advantages of high efficiency, energy saving, stable operation and long service life.

Analysis on Advantages ofOxygen Pump for Fish and Shrimp Culture

 1. Adopting bottom oxygenation technology can prevent pond hypoxia. Generally, in ponds with waterwheel oxygenators, the upper water body is rarely anoxic, but it is difficult to provide sufficient oxygen at the bottom of the pond, so the anoxia is at the bottom of the pond to make the shrimp in a sub-anoxic state. The bottom oxygenation technology is to use the air tray installed at the bottom of the pond to directly transport oxygen-containing air to the bottom of the pond, and disperse air from the bottom to the water body to supplement oxygen, so that the bottom water body can maintain high dissolved oxygen, reaching more than 5mgL, and prevent the water body from sub-hypoxia caused by bottom hypoxia. When used on cloudy or rainy days, it can also prevent the imbalance of dissolved oxygen distribution on water surface and bottom caused by water stratification after rain. 2. Ensure that the dissolved oxygen content at the bottom can inhibit the breeding of harmful microorganisms, accelerate the degradation of organic waste, reduce the content of toxic substances, activate the pond bottom, and maintain the stability of water quality physical and chemical factors. and prevent the generation of nitrite, ammonia nitrogen and hydrogen sulfide which are harmful to fish, shrimp and crab due to insufficient dissolved oxygen. Prevent prawn stress, reduce disease occurrence and improve culture success rate. 3. Energy saving. The oxygen-enrichment efficiency can be improved obviously by installing high efficiency energy-saving bottom aeration system and waterwheel aerator. Especially in the middle and late stages of culture, when oxygen supply is needed for a long time, the bottom aeration oxygen-enriched system can supply sufficient oxygen, while the energy consumption of the bottom aeration oxygen-enriched system is only one tenth of that of the waterwheel aerator. The 3 kW bottom aeration oxygen-enrichment system can simultaneously supply sufficient oxygen to a 20-acre pond. And the pond that uses waterwheel type aerator alone should be equipped with less than 1000 watts/mu. For fish, shrimp, crab breeding early seedling cover greenhouse farmers, because the greenhouse ventilation is not smooth, in the traditional aerator oxygenation effect is not obvious, the installation of energy-efficient bottom aeration oxygen-rich system effect is better. 4, through the installation of efficient energy-saving bottom aeration oxygen-rich system, to maintain the stability of water quality, improve the pond environment, improve the disease resistance of aquatic organisms, so as to effectively control the occurrence of diseases, reduce medication, reduce medication costs and feed coefficient. Through the practice contrast experiment, the cost of medicine is 0.2 yuan/jin and the feed coefficient is 0.8 in the pond installed with high efficiency energy-saving bottom aeration oxygen-enriched system. But the cost of pesticide is 0.5 yuan/jin and the feed coefficient is 1.2 without the installation of high efficiency and energy saving bottom aeration oxygen enrichment system.

Working principle of oxygen pump for raising fish and shrimp
 After the power supply is turned on, the fan rotates, because the impeller has a groove design, which will drive the air flow, so the air enters the pump body through the air inlet, and the air is stirred inside. Each groove is pressurized by vortex type, and the circulation pressure is increased one by one. Finally, a strong airflow energy is formed, which is discharged from the pump body through the air outlet for use.
Performance characteristics of aeration fan in shrimp pond
 1. Completely oil-free and water-free compression; 2. Reliable operation, ruggedness and durability; 3. Reliable design and light weight; 4. All high-pressure fan motors have IP55 protection level and F-class insulation; 5. Dual-frequency (50/60 HZ) and wide-voltage motors enable them to meet voltage levels in almost all regions of the world; 6. External bearing design enables the fan to withstand higher working temperatures and improves the fan's operating reliability and service life;  7, the introduction of a new concept of variable frequency drive, compared with the same type of motor drive performance can be increased to 300%; 8, impeller and pump body between the unique seal form to reduce the pressure loss of high-pressure gas in the compression process.

Fish and shrimp oxygen pump performance advantages
 1 , high efficiency, low energy consumption (High-pressure vortex fan has a conservative design in the high pressure range, and can still operate safely when it changes under use conditions);2. Easy installation (Can be installed in any horizontal or vertical direction);3, high reliability (Except impeller, high pressure vortex fan has no other moving parts, almost maintenance-free);4, low vibration (The mechanical precision of the high-pressure vortex fan is high, and the rotating parts are extremely precisely balanced, tested, calibrated, and the vibration rate is very low);4. Low noise (Low noise motor direct transmission, all have built-in muffler device, reduce running noise);5, solid structure (The wind surface is made of aluminum alloy and milled alloy, which is different from the general aluminum shell or iron shell fan, which is more durable);6. Wide application range (high pressure vortex fan specifications, high pressure and large air volume series, flexible selection);7. High quality (years of manufacturing experience, strict quality control, so that all parts of high pressure vortex fan can achieve high quality);9. No oil, no pollution, calm as water.
Precautions for the use offish and shrimp aeration pump

 1, sunny noon boot at this time the fish pond upper and lower water temperature difference is large, convection is very small, the oxygen in the lower water often can not be supplemented in time, open the aerator, can break through the resistance of water, so that the upper and lower water can be exchanged, temperature difference and oxygen difference will be greatly reduced, the oxygen in the lower water can be supplemented in time. 2. Sunlight intensity is weak in cloudy morning, oxygen production by photosynthesis of phytoplankton in fish pond is less, and dissolved oxygen status of the whole water body is poor. Starting the aerator in the morning when the dissolved oxygen point is low can prevent fish from floating due to lack of oxygen in the water before and after dawn. 3, rainy days in the middle of the night to start in the case of continuous rainy weather, due to the lack of sunshine for a long time, the phytoplankton photosynthesis in the fish pond is very little oxygen, so it must be turned on in the middle of the night to prevent fish from dying. 4. When the sun goes down in the evening, the photosynthesis of phytoplankton in the fish pond also stops, and oxygen can no longer be supplied to the water. If it is turned on at this time, the dissolved oxygen in the upper water body will be reduced and will not be replenished, while the dissolved oxygen in the lower water body will be consumed quickly, resulting in accelerated oxygen consumption. It is easier to have fish floating in the morning the next day. In addition, the length of time to start the aerator is also very particular: the hot weather boot time is long, the cool weather is short; the midnight boot time is long, and the noon is short; the boot time after fertilization is long, and it is short when no fertilizer is applied; the wind hour boot time is long, and the wind is short.
