這種限制破壞了平滑的流動(dòng)路徑,導(dǎo)致湍流和壓降因此,泵必須更加努力地工作以克服增加的阻力,導(dǎo)致吸入口處的壓力較低和真空增加 2.增加摩擦損失:過(guò)長(zhǎng)的管接頭由于表面積較大和流道較長(zhǎng),會(huì)帶來(lái)更多的摩擦損失當(dāng)流體流經(jīng)管道時(shí)會(huì)發(fā)生摩擦損失,這些損失與管道的長(zhǎng)度成正比。
管接頭越長(zhǎng),摩擦損失越大,這會(huì)導(dǎo)致吸入口處的壓力降低和真空增加 3.氣蝕風(fēng)險(xiǎn):由于彎曲或長(zhǎng)管接頭而導(dǎo)致吸入口真空度增加,可能導(dǎo)致氣蝕當(dāng)吸入口處的壓力低于流體的蒸氣壓時(shí),就會(huì)發(fā)生氣蝕,從而導(dǎo)致蒸氣泡的形成。
