答：以我個人對漩渦風機與羅茨風機的了解，二者之間的區別主要有以下幾種。

漩渦風機與羅茨風機的區別在哪

　　漩渦風機與羅茨風機都是依靠機械轉動帶動泵體內部的葉片旋轉，依靠離心力的作用原理，來達到壓縮氣體目的的機械設備，不過它們之間也存在一定的區別：

　　1、性質不同

　　漩渦風機屬于透平式風機，而羅茨風機屬于容積式風機。

　　2、外形不同

　　漩渦氣泵外形比較緊湊，進出風口在風機的低部，體積小，采用鋁合金材料，重量較輕，強度高;羅茨風機采用皮帶輪帶動泵腔工作，體積比較大，而制作材質為一般為鑄鐵，重量較沉。

　　3、參數不同

　　同等功率下，旋渦氣泵與羅茨風機的初始流量相差不大，壓力稍低，羅茨鼓風機因為泵腔較大，所以流量和壓力要稍高。

　　4、保養不同

　　漩渦風機基本不需要保養維護，只要注意對漩渦氣泵做簡單保養，及高壓漩渦風機軸承保養兩個方面即可;羅茨風機需要定期維護，比如加潤滑油，更新齒輪油脂等。

　　5、價格不同

　　同等功率下，漩渦氣泵價格相對比較便宜，而羅茨風機較貴。

　　二、漩渦風機和羅茨風機效率哪個好

　　漩渦風機和羅茨風機的效率比較方面并不是固定的，因為不同領域的應用需求不同，也會影響到風機的效率方面，要想知道漩渦風機和羅茨風機哪個好，我們可以來比較一下：

　　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，氣量較大，選用漩渦風機更合適一些。

　　漩渦風機與羅茨風機的區別，兩者之間的運行原理大致相同，都是依靠機械轉動帶動泵體內部的葉片旋轉，依靠離心力的作用原理，來達到壓縮氣體的目的，具體的運行可參考:漩渦氣泵運行原理，他們之間的區別主要集中在以下方面;

　　一、外形

　　漩渦氣泵外形比較緊湊，進出風口在風機的低部，體積小，采用鋁合金材料，重量較輕，強度高;羅茨風機采用皮帶輪帶動泵腔工作，體積比較大，而制作材質為一般為鑄鐵，重量較沉，耐溫性能比較差，在高溫工作時，會被氧化

　　二、參數

　　同等功率下，旋渦氣泵與羅茨風機的初始流量相差不大，壓力稍低，羅茨鼓風機因為泵腔較大，所以流量和壓力要稍高;比如污水曝氣行業，小面積一般采用旋渦氣泵的比較多，而如果大面積或水位較深的情況下，一般采用羅茨風機

　　三、保養

　　高壓鼓風機基本不需要保養維護，只要注意兩個方面即可，參考:如何對漩渦氣泵做簡單保養，及高壓漩渦風機軸承保養，壓力和進氣干凈度，使用非常方便;而羅茨風機維護定期維護，比如加潤滑油，更新齒輪油脂等，也很方便

　　四、價格

　　同等功率下，漩渦氣泵價格相對比較便宜，而羅茨風機較貴，各有各的用途，各有各的優點五、關于選擇

　　在選擇的時候，要根據自己的實現情況來看，不要一味地聽銷售人員推銷，我們選擇適合自己工況的，的才是**的結果

　　經常有客戶在選型的時候問到，羅茨風機和我們這種漩渦風機哪種好呢，有什么區別的地方呢，對于這個問題，上篇文章有講到過兩者之間的區別，不明白的客戶可以參考:漩渦氣泵與羅茨鼓風機的區別，那么羅茨風機與漩渦風機哪種更好呢，對于這個問題，還得從它們的工作原理模式開始:

　　羅茨風機:屬于容積式風機，為一個泵體中，內置有兩個葉輪，由于精密的實際及安裝位置精準，這兩個葉輪轉動時互不接觸，互不干擾，其間留有很小的間隙，以此來產生壓力和流量，因為它的泵體較大較長，所以流星也相對較大，可采用直連方式或皮帶連接方式。

　　漩渦風機:漩渦風機屬于氣環式風機，內部的葉輪邊緣有很多大小規則均勻的小葉片，并以此來產生壓力和流量，每個葉片與葉片之間都會形成一定量的漩渦式的風量，不斷加壓遞增，*終傳出泵體外部，一般為直連方式，后又生產出不帶電機的泵頭，可采皮帶連接方式。

　　在明白了兩者之間的原理之后，再來看下用途中的區別!

　　羅茨風機常用于水產養殖增氧曝氣、污水處理增氧曝氣、水泥物料的輸送等，更適用于高壓力大流量的氣體輸送和加壓系統。旋渦風機廣泛用于各類機械設備的配套，工業、化工、電子行業等都有涉及，及各類實驗室的加壓實驗裝置，可參考:漩渦氣泵可用在哪些行業和漩渦氣泵可用在哪些設備，體積小，不用維護。

　　**對于羅茨風機與漩渦風機哪種好，兩者之間不具備大多的可比性，都有各自的實用領域及優點，并且制造材質也不一樣，羅茨鼓風機為鑄鐵，旋渦風機為鋁合金，如果進氣有水汽之類的，**使用旋渦風機，如何所需要的流量很大，壓力很高，那就需要用到羅茨風機了。

　　What is the difference between vortex blower and roots blower

　　Vortex fan and Roots fan are both mechanical equipment that rely on mechanical rotation to drive the blades inside the pump body to rotate, and rely on the action principle of centrifugal force to achieve the purpose of compressing gas. However, there are certain differences between them:

　　1. Different nature

　　Vortex fan belongs to turbine fan, while Roots fan belongs to positive displacement fan.

　　2. Different shape

　　The vortex air pump is compact in shape. The air inlet and outlet are at the lower part of the fan. It is small in volume and made of aluminum alloy. It is light in weight and high in strength; Roots blower uses belt pulley to drive the pump chamber to work, which is relatively large in volume, and generally made of cast iron, which is heavy in weight.

　　3. Different parameters

　　Under the same power, the initial flow of the vortex air pump and the roots blower is similar, and the pressure is slightly lower. The roots blower has a larger pump chamber, so the flow and pressure should be slightly higher.

　　4. Different maintenance

　　The vortex fan basically does not need maintenance, as long as you pay attention to the simple maintenance of the vortex air pump and the bearing maintenance of the high-pressure vortex fan; Roots blower needs regular maintenance, such as adding lubricating oil, updating gear grease, etc.

　　5. Different prices

　　Under the same power, the price of vortex air pump is relatively cheap, while roots blower is more expensive.

　　2、 Which is better, vortex fan or Roots fan

　　The efficiency comparison between vortex blower and roots blower is not fixed, because the application requirements in different fields are different, which will also affect the efficiency of the blower. To know which is better, we can compare the vortex blower and roots blower:

　　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 vortex fan is more suitable.

　　The operating principle of vortex blower and roots blower is roughly the same. They both rely on mechanical rotation to drive the blades inside the pump body to rotate, and rely on the action principle of centrifugal force to achieve the purpose of compressing gas. For specific operation, please refer to: the operating principle of vortex air pump. The differences between them mainly focus on the following aspects;

　　1、 Profile

　　The vortex air pump is compact in shape. The air inlet and outlet are at the lower part of the fan. It is small in volume and made of aluminum alloy. It is light in weight and high in strength; Roots blower uses belt pulley to drive the pump chamber to work, which is relatively large in volume. However, its material is generally cast iron, which is heavy in weight and poor in temperature resistance. When it works at high temperature, it will be oxidized

　　2、 Parameters

　　At the same power, the initial flow of the vortex air pump and the roots blower is similar, and the pressure is slightly lower. The roots blower has a larger pump chamber, so the flow and pressure should be slightly higher; For example, in the sewage aeration industry, vortex air pumps are often used in small areas, while roots fans are generally used in large areas or deep water levels

　　3、 Maintenance

　　The high-pressure blower basically does not need to be maintained. Just pay attention to two aspects. For reference: how to do simple maintenance for the vortex air pump, and the bearing maintenance for the high-pressure vortex fan, and the pressure and air inlet cleanliness, which are very convenient to use; It is also convenient to maintain roots blower regularly, such as adding lubricating oil and updating gear grease

　　4、 Price

　　Under the same power, the price of the vortex air pump is relatively cheap, while the roots blower is more expensive. Each has its own uses and advantages. V. about selection

　　When making choices, we should look at our own implementation situation. Don't blindly listen to the sales staff. We should choose the one that suits our working conditions, and the best result is the one

　　When selecting models, customers often ask which kind of Roots blower is better than our vortex blower, and what is the difference between them. For this problem, the last article talked about the difference between the two. For customers who do not understand it, they can refer to the difference between the vortex air pump and roots blower, and which kind of Roots blower is better. For this problem, we have to start from their working principle mode:

　　Roots blower: it is a positive displacement blower. Two impellers are built in one pump body. Due to the precise actual and accurate installation position, the two impellers do not contact and interfere with each other when rotating, leaving a small gap between them to generate pressure and flow. Because its pump body is large and long, the meteor is also relatively large. Direct connection or belt connection can be used.

　　Whirlpool fan: whirlpool fan is an air ring fan. There are many small blades with regular and uniform size at the edge of the internal impeller to generate pressure and flow. A certain amount of whirlpool air volume will be formed between each blade and the blade, which will be continuously pressurized and gradually increased. Finally, it will be sent out of the pump body. Generally, it is directly connected, and then the pump head without motor will be produced. Belt connection can be adopted.

　　After understanding the principle between the two, let's look at the difference in use!

　　Roots blower is commonly used in aquaculture aeration, sewage treatment aeration, cement material transportation, etc., and is more suitable for high pressure and large flow gas transportation and pressurization systems. Vortex fans are widely used for supporting various mechanical equipment, including industrial, chemical and electronic industries, as well as pressurized experimental devices in various laboratories. For reference: in which industries and in which equipment vortex air pumps can be used, they are small and do not need maintenance.

　　Finally, there is no much comparability between Roots blower and vortex blower. Both of them have their own practical fields and advantages, and the manufacturing materials are also different. Roots blower is made of cast iron and vortex blower is made of aluminum alloy. If there is water vapor in the intake air, it is best to use vortex blower. If the flow required is very large and the pressure is very high, roots blower is needed.
