Feature：
1. The impeller adopts a new curve track. By optimizing the design, the total adiabatic efficiency and volumetric efficiency are further improved, so that the air volume and pressure are particularly excellent
2. The air inlet and exhaust shield wire of the box adopts the spiral type cut in mode, which forms a triangle air inlet and exhaust outlet with the top line of the rotor, and is opened by the rotation of the rotor in order to make the operation more balanced, thus reducing the vibration and noise of the fan
3. The structure design is adopted to avoid the bearing and gear oil mixing into the box, so that there is no oil mixing in the working chamber, so that clean gas can be obtained and air pollution caused by oil smoke can not be produced
4. Compact structure, due to the selection of special bearings and oil seals, improve the service life, and maintenance management is also convenient
5. The impeller and shaft are of split pressure fitting structure, and there is a small gap between the impellers without collision. The performance of the fan remains unchanged for a long time, and it can operate continuously for a long time. Generally, this product is only used to transport air, but it can be used to transport gas and other flammable, explosive, toxic and other special gases only by changing the sealing form. If the user has this demand, please explain it when ordering.
Product performance range: flow rate 0.44-56.97m3/min < span class = "Apple tab span" style = "white space: pre" >
Principle：
羅茨風(fēng)機(jī)為容積式風(fēng)機(jī)，輸送的風(fēng)量與轉(zhuǎn) 數(shù)成比例，三葉型葉輪每轉(zhuǎn)動(dòng)一次有2個(gè)葉輪進(jìn)行3次吸、排氣，與二葉型相比，氣體脈動(dòng)變少，負(fù)荷變化小，機(jī)械強(qiáng)度高，噪聲低，振動(dòng)也小。
在2根平行的軸上設(shè)有2個(gè)葉輪，葉輪與橢 圓形機(jī)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(zhuǎn)，使箱體和葉輪所包圍著的一定量的氣體由吸入的一側(cè)輸送到排除的一側(cè)。
舊的羅茨風(fēng)機(jī)，無論兩葉型、三葉型、其壓縮原理是：轉(zhuǎn)子頂端向排風(fēng)口一線打開的瞬間，排風(fēng)口的高壓空氣逆流與機(jī)殼之內(nèi)進(jìn)行壓縮，這種逆流與壓縮產(chǎn)生劇烈的壓力變化成了風(fēng)機(jī)的噪聲原因。本風(fēng)機(jī)為消除這種因素而研究了螺旋形狀。下圖就是本風(fēng)機(jī)螺旋形狀的要點(diǎn)說明：
