style="text-indent:25px">常見螺桿泵的特點(diǎn)和應(yīng)用，螺桿泵依靠螺桿相互嚙合（或螺桿與定子嚙合）空間的容積變化來輸送液體。當(dāng)螺桿轉(zhuǎn)動(dòng)時(shí)吸入腔一端作軸向移動(dòng)，使吸入腔的容積增大，壓力降低，液體在壓差作用下沿吸入管進(jìn)入吸入腔。隨著螺桿的轉(zhuǎn)動(dòng)，密封腔內(nèi)的液體連續(xù)而均勻地沿軸向移動(dòng)到排出腔，由于排出腔一端的容積逐漸縮小，即將液體排出。螺桿泵的特點(diǎn)是流量和壓力脈動(dòng)小、運(yùn)轉(zhuǎn)平穩(wěn)、噪聲低、效率高、壽命長(zhǎng)、有較強(qiáng)的自吸能力而且結(jié)構(gòu)簡(jiǎn)單緊湊；其突出的優(yōu)點(diǎn)是輸送介質(zhì)時(shí)不形成渦流、對(duì)介質(zhì)的粘性不敏感，可輸送高粘度介質(zhì)。螺桿泵按螺桿數(shù)目分為單螺桿泵、雙、三和五螺桿泵。單螺桿泵的結(jié)構(gòu)為單頭陽螺旋轉(zhuǎn)子在特殊的雙頭陰螺旋定子內(nèi)偏心地轉(zhuǎn)動(dòng)（定子是柔性的），能沿泵中心線來回?cái)[動(dòng)，與定子始終保持嚙合；雙螺桿泵結(jié)構(gòu)為有兩根同樣大小的螺桿軸，一根為主動(dòng)軸，一根為從動(dòng)軸，通過齒輪傳動(dòng)達(dá)到同步旋轉(zhuǎn)；三螺桿泵結(jié)構(gòu)為有一根主動(dòng)螺桿和兩根與之相嚙合的從動(dòng)螺桿所構(gòu)成；五螺桿泵的結(jié)構(gòu)為定子內(nèi)裝有五根左、右旋的螺桿軸，螺桿的共軛齒廓上有一段漸開線，它起主動(dòng)螺桿泵向從動(dòng)螺桿傳遞運(yùn)動(dòng)的作用。</p><div
