使用軟管泵如何合理降低軟管磨損

發(fā)布時間:2021-03-30 11:09 瀏覽次數(shù):

合理使用軟管泵,使得低磨損,泵軟管的壽命確定第一因素是軟管的壓縮的數(shù),第二個因素是軟管路徑,強(qiáng)度和摩擦熱的壓縮。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。加大泵腔直徑,減速泵額度運(yùn)行轉(zhuǎn)速。
