軟管泵的工作原理

發(fā)布時間:2021-04-06 14:16 瀏覽次數(shù):

軟管泵屬于蠕動泵的范疇。蠕動泵是轉(zhuǎn)子式容積泵的一種,因其工作原理類似消化道以蠕動方式輸送氣、固、液三相介質(zhì)而得名。軟管泵與蠕動泵之間沒有嚴(yán)格的區(qū)分。一般而言,蠕動泵指小流量(以毫升/分計)、低出口壓力(不超過3kg/cm2),多用于衛(wèi)生領(lǐng)域及實驗室計量。

軟管泵通過一對壓輥沿著一根特制的橡膠管旋轉(zhuǎn),將橡膠管壓扁,管子靠自身彈性在恢復(fù)原狀的過程中產(chǎn)生真空將物料吸入泵腔,然后物料在壓輥擠壓下從管內(nèi)排出。如此周而復(fù)始,物料不斷的被吸入和排出。軟管泵最大的優(yōu)勢在于:特有的無密封結(jié)構(gòu),無任何泄露污染,采用先進(jìn)的滾動技術(shù),壓輥不需要任何潤滑,自吸能力強(qiáng)并具有自清能力,能正反吸料。另一大特點是,漿料中含有固體顆粒不大于軟管內(nèi)徑1/3的情況下不影響物料輸送。
