At present, several commonly used water treatment aeration blowers mainly include roots blower, rotary blower and water ring blower. They are low-noise or silent blowers, among which the water ring blower is an environmentally friendly model.

隨著人們意識的增強(qiáng)，對要求越來越嚴(yán)格，產(chǎn)業(yè)也得到了高速發(fā)展，對水處理的要求越來越高，特別是水處理工作中的核心部件-曝氣鼓風(fēng)機(jī)，相關(guān)行業(yè)規(guī)定要求曝氣鼓風(fēng)機(jī)運(yùn)行不能產(chǎn)生二次污染，需要低噪音運(yùn)行。

With the enhancement of people's awareness of environmental protection, the national requirements for environmental protection are becoming more and more strict, and the environmental protection industry has also developed rapidly. The national requirements for environmental protection water treatment are becoming higher and higher, especially the core component of water treatment - aeration blower. Relevant industry regulations require that the operation of aeration blower can not produce secondary pollution and needs low noise operation.

目前常用的三葉羅茨鼓風(fēng)機(jī)，和二葉相比，噪音要低很多，但是由于羅茨鼓風(fēng)機(jī)是齒輪傳動(dòng)，它每轉(zhuǎn)動(dòng)一周，排氣吸氣3次，進(jìn)排氣脈動(dòng)噪音是風(fēng)機(jī)大的噪音污染源，而且如果齒輪油箱泄漏也會(huì)產(chǎn)生機(jī)油的污染。

At present, the noise of the commonly used three blade roots blower is much lower than that of the two blades. However, because the roots blower is gear driven, it exhausts and sucks in three times every week. The pulsating noise of inlet and exhaust is the big noise pollution source of the fan, and the oil pollution will also be caused if the gear oil tank leaks.

回轉(zhuǎn)式鼓風(fēng)機(jī)相對于羅茨鼓風(fēng)機(jī)而言，噪音較低，由于回轉(zhuǎn)風(fēng)機(jī)是油潤滑風(fēng)機(jī)，排氣口易產(chǎn)生二次污染，如果缺油，將會(huì)增加磨損，產(chǎn)生噪音，損壞風(fēng)機(jī)，因此對于回轉(zhuǎn)式鼓風(fēng)機(jī)而言，油的潤滑十分重要。

Compared with roots blower, the noise of rotary blower is relatively low. Since the rotary blower is an oil lubricated fan, the exhaust port is easy to produce secondary pollution. If there is a lack of oil, it will increase wear, produce noise and damage the fan. Therefore, oil lubrication is very important for rotary blower.

水環(huán)式鼓風(fēng)機(jī)的工作液是水，不會(huì)產(chǎn)生油污染，也不會(huì)存在任何機(jī)械噪音和機(jī)械磨損。風(fēng)機(jī)葉輪有16只葉片將空間分成16個(gè)工作空間，風(fēng)機(jī)每轉(zhuǎn)動(dòng)一周，排氣吸氣16次，能降低風(fēng)機(jī)脈動(dòng)噪音，是目前為的水處理曝氣風(fēng)機(jī)。

The working fluid of water ring blower is water, which will not produce oil pollution, mechanical noise and mechanical wear. The fan impeller has 16 blades, which divides the space into 16 working spaces. The fan exhausts and inhales 16 times every week, which can reduce the pulsating noise of the fan. At present, it is an environmental friendly water treatment aeration fan.

當(dāng)然，用戶選擇水處理曝氣鼓風(fēng)機(jī)時(shí)，應(yīng)根據(jù)實(shí)際應(yīng)用情況，考慮風(fēng)機(jī)成本、運(yùn)行費(fèi)用以及后續(xù)維護(hù)等來綜合選擇，不能一味的以風(fēng)量和產(chǎn)生的噪音分貝數(shù)來進(jìn)行選擇，不一定要選擇貴的，但要選擇合適的。

Of course, when users choose water treatment aeration blowers, they should comprehensively select them according to the actual application, considering the fan cost, operation cost and subsequent maintenance. They can't choose them blindly based on the air volume and noise decibels. They don't have to choose expensive ones, but they should choose appropriate ones.
