Many customers generally came into contact with roots blower earlier, and then with rotary blower. At the beginning, they may not be very clear about what rotary blower is used for, what principle it is, and what advantages it has. Now they are basically clear.

回轉(zhuǎn)式風(fēng)機(jī)，又叫滑片鼓風(fēng)機(jī)，是容積式風(fēng)機(jī)的一種，因?yàn)槠涞驮胍舻奶匦裕脖怀蔀榈驮胍艋剞D(zhuǎn)風(fēng)機(jī)?；剞D(zhuǎn)鼓風(fēng)機(jī)是眾多風(fēng)機(jī)的一種類型，是一種經(jīng)過(guò)壓縮空氣來(lái)完成曝氣的風(fēng)機(jī)，所以又名曝氣鼓風(fēng)機(jī)。它主要由電機(jī)、空氣過(guò)渡器、鼓風(fēng)機(jī)本體、空氣室、底座(兼油箱)、滴油嘴六部份構(gòu)成。鼓風(fēng)機(jī)靠汽缸內(nèi)偏置的轉(zhuǎn)子偏心作業(yè)并使轉(zhuǎn)子槽中的葉片之間的容積改變將空氣吸入、壓縮、排出。

Rotary fan, also known as sliding blade blower, is a kind of positive displacement fan. Because of its low-noise characteristics, it is also called low-noise rotary fan. Rotary blower is a type of many fans, which completes aeration through compressed air, so it is also called aeration blower. It is mainly composed of six parts: motor, air transition device, blower body, air chamber, base (also used as oil tank) and oil drip nozzle. The blower works eccentrically by the offset rotor in the cylinder and changes the volume between the blades in the rotor slot to suck in, compress and discharge air.

回轉(zhuǎn)式風(fēng)機(jī)是現(xiàn)在比較常見(jiàn)的類型，具有體積小、風(fēng)量大，低噪音、安裝方便、耐久性強(qiáng)、運(yùn)行平穩(wěn)、低廉等特點(diǎn)，回傳式鼓風(fēng)機(jī)主要用于小型污水處理。污水處理為什么會(huì)用到回轉(zhuǎn)鼓風(fēng)機(jī)呢，小型水處理多采用活性污泥法，這種處理方法需氧性生物進(jìn)行處理，在處理過(guò)程中，須確保水中有一定量的溶解氧，達(dá)到維持微生物生命活動(dòng)的目的，回轉(zhuǎn)式風(fēng)機(jī)在其中起到增氧的作用。

Rotary fan is a relatively common type now, which has the characteristics of small volume, large air volume, low noise, convenient installation, strong durability, stable operation, low price, etc. the return fan is mainly used for small sewage treatment. Why do rotary blowers are used in sewage treatment? Activated sludge method is often used in small water treatment. This treatment method requires aerobic organisms to treat. In the process of treatment, it is necessary to ensure that there is a certain amount of dissolved oxygen in the water, so as to maintain the life activities of microorganisms, in which rotary fans play the role of increasing oxygen.

在多年前，回轉(zhuǎn)風(fēng)機(jī)使用量并不是很大，因?yàn)檩^適用于對(duì)噪音要求較嚴(yán)格的小型水處理工程，因而較多用于小區(qū)污水處理，所謂的小區(qū)污水處理，包括景區(qū)、旅游區(qū)、高速服務(wù)區(qū)等的污水處理，也包括醫(yī)療廢水處理等。隨著近些年積極響應(yīng)“金山銀山就是綠水青山”的號(hào)召，大力推進(jìn)新農(nóng)村建設(shè)，農(nóng)村污水治理越來(lái)越被重視，各地農(nóng)村污水處理項(xiàng)目陸續(xù)上馬，成為回轉(zhuǎn)式鼓風(fēng)機(jī)使用率占比較大的市場(chǎng)。比如，在浙江杭州淳安千島湖，這里是5A級(jí)風(fēng)景區(qū)，對(duì)污水處理和水環(huán)境的改善有著比較嚴(yán)格甚苛刻的要求，諸多小型污水處理項(xiàng)目，幾百上千的水處理項(xiàng)目，基本都是采用了低噪音回轉(zhuǎn)式鼓風(fēng)機(jī)。

Many years ago, the use of rotary fans was not large, because they were more suitable for small-scale water treatment projects with strict noise requirements, so they were mostly used for community sewage treatment. The so-called community sewage treatment includes sewage treatment in scenic spots, tourist areas, high-speed service areas, etc., as well as medical wastewater treatment. In recent years, with the positive response to the call of "Jinshan Yinshan is green water and green mountains" and the vigorous promotion of new rural construction, rural sewage treatment has been paid more and more attention. Rural sewage treatment projects have been launched one after another around the country, becoming a market with a relatively large utilization rate of rotary blowers. For example, Qiandao Lake in Chun'an, Hangzhou, Zhejiang Province, is a 5A scenic spot, which has relatively strict or even stringent requirements for sewage treatment and water environment improvement. Many small sewage treatment projects, hundreds of thousands of water treatment projects, basically use low-noise rotary blowers.

很多人知道羅茨風(fēng)機(jī)是羅茨兄弟發(fā)明的，其實(shí)回轉(zhuǎn)風(fēng)機(jī)也是由他們發(fā)明。隨著市場(chǎng)對(duì)回轉(zhuǎn)風(fēng)機(jī)需求增加和應(yīng)用的普及，國(guó)內(nèi)回轉(zhuǎn)風(fēng)機(jī)廠家也越來(lái)越多了，但行業(yè)內(nèi)人士表示，一直沒(méi)有大型回轉(zhuǎn)風(fēng)機(jī)廠家。比如，有些人會(huì)問(wèn)哪家回轉(zhuǎn)風(fēng)機(jī)好，什么企業(yè)回轉(zhuǎn)風(fēng)機(jī)好，有些人拿自己的企業(yè)跟道源羅茨風(fēng)機(jī)放在一起說(shuō)，其實(shí)，回轉(zhuǎn)風(fēng)機(jī)技術(shù)和生產(chǎn)都已經(jīng)很成熟，只要是較有實(shí)力的回轉(zhuǎn)風(fēng)機(jī)廠家，按照標(biāo)準(zhǔn)生產(chǎn)良心產(chǎn)品，都能夠用的住、用得好。

Many people know that the roots blower was invented by the roots brothers. In fact, the rotary blower was also invented by them. With the increasing demand for rotary fans in the market and the popularity of applications, there are more and more domestic manufacturers of rotary fans, but people in the industry say that there has been no large-scale manufacturers of rotary fans. For example, some people will ask which rotary fan is good and what brand of rotary fan is good. Some people put their own brand together with Daoyuan Roots fan. In fact, the technology and production of rotary fan are very mature. As long as it is a more powerful rotary fan manufacturer and produces products according to the standards, it can be used and used well.

我們看到，在回轉(zhuǎn)風(fēng)機(jī)用途表述中，有好多關(guān)于回轉(zhuǎn)風(fēng)機(jī)的用途說(shuō)明，但是，回轉(zhuǎn)風(fēng)機(jī)除了用于水處理曝氣，還有在醫(yī)院、實(shí)驗(yàn)室、電鍍槽攪拌中運(yùn)用比較多，在其他行業(yè)，比如印刷業(yè)送紙、工業(yè)廢水?dāng)嚢?、塑焊及吹風(fēng)氣源供應(yīng)、燃燒器噴霧、玻璃工業(yè)等這些方面，運(yùn)用比例還是少的多。橫向比較，現(xiàn)在用低噪音回轉(zhuǎn)風(fēng)機(jī)的較多的，當(dāng)屬農(nóng)村和小區(qū)污水處理，也常被用于一體污水配套。

We can see that in the description of the use of rotary fans, there are many descriptions about the use of rotary fans. However, in addition to being used for water treatment and aeration, rotary fans are also widely used in hospitals, laboratories and electroplating tank mixing. In other industries, such as printing paper feeding, industrial wastewater mixing, plastic welding and blowing air supply, burner spray, glass industry, etc., the application proportion is still much smaller. Horizontal comparison, now more low-noise rotary fans are used, which belong to rural and community sewage treatment, and are often used for integrated sewage matching.

羅茨風(fēng)機(jī)是一種高壓風(fēng)機(jī),與回轉(zhuǎn)風(fēng)機(jī)相比較，壓力高、能耗高、噪音大，如果需要風(fēng)壓和風(fēng)量較小，要求噪音較低，選用回轉(zhuǎn)式鼓風(fēng)機(jī)是更好的選擇。

Roots blower is a kind of high-pressure blower. Compared with rotary blower, it has high pressure, high energy consumption and high noise. If the air pressure and air volume are required to be small and the noise is required to be low, rotary blower is a better choice.
