三葉羅茨風(fēng)機(jī)是一種雙葉輪同步壓縮機(jī)械，每個(gè)三葉型轉(zhuǎn)子用兩個(gè)軸承支承，利用一對(duì)同步齒輪，使兩個(gè)轉(zhuǎn)子的相對(duì) 位置始終保持不變。屬容積式鼓風(fēng)機(jī)，具有強(qiáng)制輸氣特征。三葉羅茨風(fēng)機(jī)作為回轉(zhuǎn)式機(jī)械，具有比較穩(wěn)定的工作特性，  三葉羅茨風(fēng)機(jī)轉(zhuǎn)子與轉(zhuǎn)子、轉(zhuǎn)子與泵體｀轉(zhuǎn)子與側(cè)蓋之間都有微小間隙，因而工作腔內(nèi)沒有摩擦，無接觸磨損部分，三葉羅茨風(fēng)機(jī)經(jīng)濟(jì)耐用，無需潤(rùn)淆，使用壽命長(zhǎng)，動(dòng)力平衡性好．運(yùn)轉(zhuǎn)一周有六次吸排氣過程，容積效率離結(jié)構(gòu)簡(jiǎn)單，使用維護(hù)方便 不需要內(nèi)部潤(rùn)滑，輸送的介質(zhì)不含油等特點(diǎn)。泵轉(zhuǎn)子的支承采用了可靠的消隙結(jié)構(gòu)，轉(zhuǎn)動(dòng)部件作細(xì)致的動(dòng)平衡，并采用高精度的斜齒輪，因此，運(yùn)行平穩(wěn)，噪聲低，使用更加可靠，可在商壓差下長(zhǎng)期運(yùn)行．

羅茨風(fēng)機(jī)廣泛應(yīng)用于陶盜、建材、造紙、電業(yè)、石油、化工、紡織、水產(chǎn)養(yǎng)殖、污水處理、食品等行業(yè)的氣力輸送系統(tǒng)．

The three-lobe Roots blower is a two- impeller synchronous compressionmachine . Each three-bladed rotor 1s supported by two bearings. A pair of synchronous gears are used to keep the relative positions of the two rotors constant. It is a positive displacement blower with forced gas transmission chara cteristics  As a rotary machine, the three-leaf Roots blower has relatively stable working characteristics. There is a slight gap between the rotor and rotor of the three-lobe Roots blower, the rotor and the pump body, and the rotor and the side cover. Therefore, there is no friction in the working chamber. contact with the wear part; the three-leaf Roots blowe is economical and durable,requires no lubrication, has a long service life and good dynamic balance. There  are six suction and exhaust processes in one week of operation. The volumetric efficiency is high, the structure is simple, the use and maintenance are convenient, no internal lubrication is required, and the medium to be transported does not contain 0il..  The support of the pump rotor adopts a reliable anti-backlash structure, the rotating parts are carefully balanced, and the high-precision helical gear is used There fore, the operation is stable, the noise is low, the use is more reliable, and the long-term operation can be performed under the high pressure difference.

Roots blowers are widely used in the pneumatic conveying systems of ceramics,building materials, paper, electricity, petroleum,chemical, textile, aquaculture, sewage treatment,food and other industries.
