Using the bottom of microporous pipeline to increase oxygen in the pond can improve the dissolved oxygen in the pond. The dissolved oxygen is evenly distributed and has a wide range of oxygen increase. It is especially suitable for benthic aquatic animals, such as river crab, shrimp, fish, etc. Microporous pipeline oxygenation technology can appropriately increase the pond culture density, improve the culture yield and increase economic benefits

1.增氧泵原理 采用高壓鼓風機將空氣送入輸氣管道，輸氣管道將空氣送入微孔管，微孔管將空氣以微氣泡形 式分散到水中，微氣泡由池底向上浮，氣泡在氣體高氧分壓作用下，氧氣充分溶入水中，還可造成水流的旋 轉(zhuǎn)和上下流動，水流的上下流動將上層富含氧氣的水帶入底層，同時水流的旋轉(zhuǎn)流動將微孔管周圍富含氧氣 的水向外擴散，實現(xiàn)池水的均勻增氧

1. The principle of the oxygenation pump uses the high-pressure blower to send the air to the gas transmission pipeline, which sends the air to the microporous pipe, which disperses the air into the water in the form of micro bubbles, which float upward from the bottom of the pool. Under the action of high oxygen partial pressure of the gas, the oxygen is fully dissolved in the water, which can also cause the rotation and up and down flow of the water flow, and the up and down flow of the water flow will bring the oxygen rich water in the upper layer to the bottom layer, At the same time, the rotating flow of the water will diffuse the oxygen rich water around the microporous tube outward, so as to realize the uniform oxygenation of the pool water

2.增氧泵結(jié)構(gòu) 微孔增氧設(shè)施主要有主機高壓鼓風機(轉(zhuǎn)速2800轉(zhuǎn)/分)、儲氣緩沖裝置、主管、支管、曝氣管等組成

2. Aerating pump structure microporous aerating facilities are mainly composed of main engine high-pressure blower (speed 2800 RPM), gas storage buffer device, main pipe, branch pipe, aeration pipe, etc

3.增氧泵安裝 電機驅(qū)動高壓鼓風機，高壓鼓風機連接儲氣緩沖裝置，儲氣緩沖裝置連接主管，主管接支管，支管接曝氣管。每667配備功率2.2千瓦鼓風機，曝氣管總長度在60米左右，管間距10米左右，高低相差不超過10厘米，固定后離池底10~15厘米

3. The oxygenation pump is installed with a motor driven high-pressure blower, which is connected to the gas storage buffer device, the gas storage buffer device is connected to the main pipe, the main pipe is connected to the branch pipe, and the branch pipe is connected to the aeration pipe. A blower with a power of 2.2 kW is equipped every 667 square meters. The total length of the aeration pipe is about 60 meters, the pipe spacing is about 10 meters, the height difference is no more than 10 cm, and it is 10 ~ 15 cm away from the bottom of the tank after fixing

4.增氧泵使用方法 根據(jù)水體溶解氧變化的規(guī)律，確定開機增氧的時間和時段。一般4~5月，陰雨天半夜開機；6~10月下午開機2~3小時，日出之前1小時開機2~3小時，連續(xù)陰雨或低壓天氣，夜間9時開機持續(xù)到第2天中午；養(yǎng)殖后期勤開機，**水產(chǎn)養(yǎng)殖對象生長。有條件的進行溶氧檢測，適時開機，以保證水體溶氧在每升6~8毫克為佳

4. Use method of oxygenation pump determine the start-up time and period of oxygenation according to the change law of dissolved oxygen in water. Generally, it starts at midnight in rainy days from April to May; Start the machine for 2-3 hours in the afternoon of June to October, 1 hour before sunrise and 2-3 hours in continuous rainy or low-pressure weather. Start the machine at 9:00 at night and continue to noon the next day; Start up frequently in the later stage of aquaculture, * * aquaculture objects grow. Carry out dissolved oxygen detection conditionally and start the machine in time to ensure that the dissolved oxygen in the water body is 6 ~ 8 mg / L

5.增氧泵特點，靜音無干擾。水底微孔曝氣管微型氣泡上升過程緩慢，管壁中微小開孔的曲折通道是空氣的微滲道管，速度慢阻力小，孔眼密集，在水中水面基本沒有聲音，對魚蝦蟹正常活動無干擾。二，增氧效果好。微孔管微氣泡增氧，微氣泡可以迅速增加水中的含氧量，因此增氧效率高、效果好。特別對于陰雨天中高密度養(yǎng)殖，采用微孔增氧能馬上解決魚群缺氧浮頭現(xiàn)象，達到水面葉輪增氧難以達到的效果。三，能耗費用少。由于采用微孔曝氣增氧裝置，氧的傳輸效率非常高，使單位水體溶氧迅速達到4.5毫克/升左右，能耗不到水車或葉輪增氧的1/4，可以大大節(jié)約養(yǎng)殖戶的電費成本

5. The oxygenation pump features quiet and no interference. The rising process of micro bubbles in the underwater microporous aeration pipe is slow. The zigzag channel with small openings in the pipe wall is the micro infiltration pipe of air. The speed is slow, the resistance is small, and the holes are dense. There is basically no sound on the water surface, which does not interfere with the normal activities of fish, shrimp and crab. 2、 Good oxygenation effect. The micro bubble in the microporous tube can rapidly increase the oxygen content in the water, so the oxygenation efficiency is high and the effect is good. Especially for medium and high-density aquaculture in cloudy and rainy days, microporous oxygenation can immediately solve the phenomenon of anoxic floating head of fish, and achieve the effect that it is difficult to achieve by water surface impeller oxygenation. 3、 Low energy consumption. Due to the use of microporous aeration oxygenation device, the oxygen transmission efficiency is very high, so that the dissolved oxygen per unit water body quickly reaches about 4.5 mg / L, and the energy consumption is less than 1 / 4 of that of waterwheel or impeller, which can greatly save the electricity cost of farmers
