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.

Principle:

罗茨风机为容积式风机,输送的风量与转 数成比例,三叶型叶轮每转动一次有2个叶轮进行3次吸、排气,与二叶型相比,气体脉动变少,负荷变化小,机械强度高,噪声低,振动也小。

在2根平行的轴上设有2个叶轮,叶轮与椭 圆形机箱内孔面及各叶轮三者之间始终保持微小的间隙,由于叶轮互为反方向匀速旋转,使箱体和叶轮所包围着的一定量的气体由吸入的一侧输送到排除的一侧。

旧的罗茨风机,无论两叶型、三叶型、其压缩原理是:转子顶端向排风口一线打开的瞬间,排风口的高压空气逆流与机壳之内进行压缩,这种逆流与压缩产生剧烈的压力变化成了风机的噪声原因。本风机为消除这种因素而研究了螺旋形状。下图就是本风机螺旋形状的要点说明:
