　　4、氧氣傳質效率非常高，采用微孔曝氣曝氣裝置，使單位水中的溶解氧迅速達到4.6mg/L或不到運水車或葉輪曝氣能耗的四分之一，可以大大節(jié)省農(nóng)民的電費。

　　5、實現(xiàn)生態(tài)養(yǎng)殖，保障養(yǎng)殖效益：持續(xù)補充微孔氧，為水體提供充足的溶解氧，恢復和促進水體自凈能力，建立菌藻相自然平衡，可以構建水體自然生態(tài)，不能無序提高養(yǎng)殖種群的生存能力，充分保證養(yǎng)殖效益。

　　6、安全環(huán)保：安裝在岸邊的微孔曝氣曝氣曝氣裝置具有良好的安全功能，不會對水體帶來任何污染。其他的曝氣方式是在水中工作，容易漏電，燒毀機器，對人體和魚蝦危害很大。

　　7、維護方便：羅茨風機輕便、耐用、維護簡單方便、節(jié)能環(huán)保、維護性好。

　　要看你的魚塘有多大，如果只是幾平方，那就用旋渦，如果幾畝那就得用羅茨風機了，其實旋渦風機和羅茨風機都叫高壓風機，都是工作壓力較高的風機。

　　渦輪高壓風機又叫漩渦氣泵，其工作原理是：當葉輪轉動時，由于離心力的作用，風向標促使氣體向前向外運動，從而形成一系列螺旋狀的運動。葉輪刀片之間的空氣呈螺旋狀加速旋轉并將泵體之外的氣體擠入(由吸氣口吸入)側槽,當它進入側通道以后，氣體被壓縮，然后又回復到葉輪刀片間再次加速旋轉。當空氣沿著一條螺旋形軌道穿過葉輪和側槽時，每個葉輪片增加了壓縮和加速的程度,隨著旋轉的進行，氣體的動能增加，使得沿側通道通過的氣體壓力進一步增加。當空氣到達側槽與排放法蘭的連接點(側通道在出口處變窄)，氣體即被擠出葉片并通過出口消聲器排出泵體。

　　羅茨風機為容積式風機，輸送的風量與轉數(shù)成比例，三葉型葉輪每轉動一次由2個葉輪進行3次吸、排氣，與二葉型相比，氣體脈動變少，負荷變化小，機械強度高，噪聲低，振動也小。在2根平相行的軸上設有2個三葉型葉輪，輪與橢圓形機箱內(nèi)孔面及各葉輪三者之間始終保持微小的間隙，由于葉輪互為反方向勻速旋轉，使箱體和葉輪所包圍著的一定量的氣體由吸入的一側輸送到排出的一側。各支葉輪始終由同步齒輪保持正確的相位，不會出現(xiàn)互相碰觸現(xiàn)象，因而可以高速化，不需要內(nèi)部潤滑，而且結構簡單，運轉平穩(wěn)，性能穩(wěn)定，適應多種用途，已運用于廣泛的領域。旋渦風機和羅茨風機有很大的區(qū)別，結構形式和工作原理及工作特性都不同。

　　簡單來說，旋渦風機是靠離心力將氣體送出，羅茨風機是強制輸送氣體，也就是壓縮氣體輸送。以污水處理為例，漩渦風機適用于小型的水池供氧，經(jīng)濟劃算;羅茨風機使用于大型的污水處理，風壓比較大。選用時根據(jù)你使用的壓力和氣量，一般風壓大，氣量大的選羅茨風機的更適合。但如果風壓在20KPa以內(nèi)，氣量較大，可以選用環(huán)形風機，較為合理。設備選用方面，羅茨風機使用建議百事德或錦工即可，漩渦風機可以選擇格凌或森茲，都是國產(chǎn)的性價比比較高，比較皮實耐用的。

　　總之，蟹塘面積小就選用旋渦風機增氧，面積大的就選用羅茨風機增氧!

　　Fish, shrimps and crabs all need oxygen enriched equipment. Roots blower has a good effect in aquaculture. The use of oxygenated roots blowers in aquaculture can solve the problem of anoxia and floating head.

　　Why are roots blowers used in aquaculture? Nowadays, there are more and more fish farming. From the point of view of the social invention of fish pond aeration to help fish farmers solve problems, some people may not know much about the roots blower for fish pond aeration, nor do they know what help the roots blower for fish pond aeration can bring to breeding users. fish culture. Roots blower is an indispensable fishery machinery for fish farmers. Using roots blower can improve water quality. The aerobic roots blower not only supplies the oxygen required by fish, but also promotes the oxidative decomposition of organic matter in the pond, promotes the convection between water, increases the dissolved oxygen in the bottom layer, and reduces the presence of harmful substances such as hydrogen sulfide and ammonia in the bottom layer. Improve fish habitat, improve physique, enhance vitality, and promote production increase. The improvement of water quality is more important than the bait environment. This is why fish (shrimp) should be raised first. Only when it is used correctly can it play a greater role.

　　Advantages of Roots blower for fishpond oxygenation

　　1. the fishpond oxygen enriched roots blower has large contact surface with water, low floating speed, long contact time and high oxygen mass transfer efficiency due to the bubbles generated by the ultra microporous pores of the nano aeration pipe

　　2. fully activate the water body: the microporous aeration device seems to turn the water body into hundreds of millions of surging streams. Sufficient dissolved oxygen enables the water body to establish a natural ecosystem and make the water body vibrant.

　　3. Restore the self purification function of water body: microporous aeration is bottom aeration, other aeration is surface aeration, and the aquaculture water body is mainly anoxic at the bottom. The refractory organics such as fertilizer sludge, organic excreta and residual deteriorated bait deposited at the bottom of the water body will consume a lot of oxygen, while appropriate microporous aeration will increase oxygen. It can be transformed into organic matter dissolved and decomposed by microorganisms to restore the self purification function of water body.

　　4. The oxygen mass transfer efficiency is very high. The microporous aeration device can quickly make the dissolved oxygen in unit water reach 4.6mg/l or less than one fourth of the aeration energy consumption of the water tanker or impeller, which can greatly save farmers' electricity bills.

　　5. To realize ecological aquaculture and ensure the benefits of aquaculture: continuously supplement microporous oxygen, provide sufficient dissolved oxygen for the water body, restore and promote the self purification capacity of the water body, and establish a natural balance between bacteria and algae, which can build the natural ecology of the water body, can not disorderly improve the viability of the aquaculture population, and fully ensure the benefits of aquaculture.

　　6. Safety and environmental protection: the microporous aeration device installed on the bank has good safety function and will not bring any pollution to the water body. Other aeration methods work in water, which is easy to leak electricity and burn the machine, which is very harmful to human body, fish and shrimp.

　　7. Convenient maintenance: Roots blower is light, durable, easy and convenient to maintain, energy saving, environmental protection and good maintainability.

　　It depends on the size of your fish pond. If it is only a few square meters, use vortex. If it is a few acres, use roots fans. In fact, both vortex fans and roots fans are called high-pressure fans, both of which are fans with high working pressure.

　　Turbine high-pressure fan is also called vortex air pump. Its working principle is that when the impeller rotates, due to the action of centrifugal force, the wind vane promotes the gas to move forward and outward, thus forming a series of spiral movements. The air between the impeller blades spirally accelerates the rotation and pushes the gas outside the pump body into the side groove (inhaled by the suction port). When it enters the side channel, the gas is compressed, and then it returns to the impeller blades to accelerate the rotation again. When the air passes through the impeller and side grooves along a spiral track, each impeller blade increases the degree of compression and acceleration. With the rotation, the kinetic energy of the gas increases, which further increases the gas pressure passing along the side channel. When the air reaches the connection point between the side slot and the discharge flange (the side channel narrows at the outlet), the gas is extruded out of the blade and discharged from the pump body through the outlet muffler.

　　Roots blower is a positive displacement fan, and the air volume conveyed is proportional to the number of revolutions. Each time the three blade impeller rotates, two impellers carry out three times of suction and exhaust. Compared with the two blade type, the gas pulsation is less, the load change is small, the mechanical strength is high, the noise is low, and the vibration is small. Two three blade impellers are set on two parallel shafts. A small gap is always maintained between the impeller and the inner hole surface of the oval case and each impeller. As the impellers rotate at a uniform speed in the opposite direction to each other, a certain amount of gas surrounded by the box and the impeller is transmitted from the suction side to the discharge side. Each impeller is always kept in the correct phase by the synchronous gear without touching each other. Therefore, it can be high-speed, does not need internal lubrication, and has simple structure, stable operation and stable performance. It is suitable for a variety of purposes and has been used in a wide range of fields. There are great differences between vortex fan and Roots fan in structure, working principle and working characteristics.

　　To put it simply, the vortex fan sends out the gas by centrifugal force, and the Roots fan forcibly transports the gas, that is, compressed gas. Taking sewage treatment as an example, the vortex fan is suitable for supplying oxygen to small pools, which is economical and cost-effective; Roots blower is used for large-scale sewage treatment with high wind pressure. According to the pressure and air volume you use, the roots blower is more suitable for large air pressure and large air volume. However, if the wind pressure is within 20KPa and the air volume is large, the annular fan can be selected, which is more reasonable. In terms of equipment selection, PepsiCo or Jingong is recommended to use roots blower, and Geling or SENZ can be selected as vortex blower, both of which are made in China with high cost performance and durable leather.

　　In short, the small crab pond area will be aerated by the vortex fan, and the large crab pond area will be aerated by the Roots fan!
