Kev faib tawm thiab kev siv cov kua dej peristaltic tso tsheb

Peristaltic tso cov twj tso kua mis yog cov khoom sib xyaw ua ke ntawm cov nqus twj ua haujlwm hauv lub cev, thiab lawv tau dav dav thiab siv. Raws li cov ntaub ntawv sib txawv, tshuaj sib txawv Hoses yog muab faib ua silicone, PVC hoses, fluororubber hoses thiab polyurethane hoses. Silicone Hoses feem ntau yog siv nyob rau hauv cov tshuaj thiab khoom noj khoom noj vim lawv cov biocompatibility thiab kub tsis kam; PVC hoses tau siv dav hauv cov tshuaj lom neeg thiab kev kuaj kab sim teb vim lawv tus nqi qis thiab tshuaj muaj kev ruaj khov; Fluororubber Hoses muaj tshuaj lom neeg lom zem heev thiab haum rau cov pa roj acid thiab alkali ib puag ncig; Hosesane Hoses feem ntau siv nyob rau hauv high-}}}}} pa ib puag ncig vim lawv lub siab hnav tsis kam thiab kua muag tiv taus. Tsis tas li ntawd, penessaltic tso kua mis hoses kuj tseem tau ua raws li cov tsis muaj qhov zoo li sab hauv lub taub, phab ntsa tuab thiab ntev kom tau raws li cov kev xav tau ntawm cov kev xav tau ntawm cov nqi sib txawv thiab kev sib tw. Xaiv ib qho haum peristaltic twj tso kua mis hose tsis tuaj yeem txhim kho kev ua haujlwm ntawm kev ua haujlwm ntawm lub twj tso kua mis, tab sis kuj txuas ntxiv nws txoj kev pabcuam lub neej.
