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 vane blower, is a kind of volumetric fan. Because of its low noise characteristics, it is also called low noise rotary fan. Rotary blower is a type of many fans. It is a kind of fan that 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 (and oil tank), and drip nozzle. The blower works by eccentric rotor in the cylinder and changes the volume between the blades in the rotor slot to suck in, compress and exhaust the 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 common type now, with small volume, large air volume, low noise, convenient installation, strong durability, stable operation and low price. Rotary fan is mainly used for small sewage treatment. Why is rotary blower used for sewage treatment? Activated sludge method is often used for small water treatment. This treatment method is aerobic biological treatment. During the treatment process, it is necessary to ensure that there is a certain amount of dissolved oxygen in the water to maintain the life activities of microorganisms, and rotary blower plays a role in increasing oxygen.

 
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)嚢琛⑺芎讣按碉L(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,，也常被用于一體化污水配套,。
In the description of the use of rotary fans, there are many descriptions about the use of rotary fans. However, in addition to water treatment and aeration, rotary fans are also used more frequently in hospitals, laboratories, and electroplating tank mixing. In other industries, such as paper feeding in the printing industry, industrial wastewater mixing, plastic welding and air supply for blowing, burner spray, glass industry, etc., the proportion of application is much less. In horizontal comparison, most of the low-noise rotary fans are used for rural and residential sewage treatment, and are often used for integrated sewage matching.
回轉(zhuǎn)風(fēng)機(jī)運(yùn)轉(zhuǎn)時(shí),，鼓風(fēng)機(jī)靠汽缸內(nèi)偏置的轉(zhuǎn)子偏心運(yùn)轉(zhuǎn)，并使轉(zhuǎn)子槽中的葉片之間的容積變化將空氣吸入,、壓縮,、吐出，各部件之間相互摩擦產(chǎn)生摩擦熱,。風(fēng)機(jī)在運(yùn)轉(zhuǎn)中,，利用鼓風(fēng)機(jī)的壓力差自動(dòng)將潤(rùn)滑油送到滴油嘴。由滴油嘴往汽缸體內(nèi)滴入必要的潤(rùn)滑油,，使摩擦表面潤(rùn)滑,，以減少摩擦熱和摩擦噪音；并使部件之間形成一層油膜,，保持風(fēng)機(jī)的密封性,，同時(shí)可保持汽缸內(nèi)氣體不回流。這是回轉(zhuǎn)風(fēng)機(jī)潤(rùn)滑油的作用,。
When the rotary fan is running, the blower operates eccentrically by the biased rotor in the cylinder, and the volume change between the blades in the rotor slot will suck in, compress and spit out the air, and the friction heat will be generated by the friction between the components. When the fan is running, the pressure difference of the blower is used to automatically send the lubricating oil to the drip nozzle. Drip necessary lubricating oil into the cylinder body from the oil drip nozzle to lubricate the friction surface to reduce friction heat and friction noise; A layer of oil film is formed between the components to maintain the tightness of the fan and keep the gas in the cylinder from flowing back. This is the function of lubricating oil for rotary fan.
