Iinkqubo yokugqobhoza ukuwelangowona matshini usetyenziswa kakhulu ekuveliseni imibhobho yentsimbi engenamthungo, kwaye yasungulwa ngabazalwana baseJamani baseMannesmann ngowe-1883. Iziphene zomgangatho we-capillary eziveliswa ngokuqengqeleka kunye nokugqojozwa kwetyhubhu engenanto ikakhulu ibandakanya ukugotywa kwangaphakathi, ukugoba kwangaphandle, ubukhulu bodonga olungalinganiyo kunye nemikrwelo yomphezulu we-capillary.

I-Capillary infolding: I-Capillary sesona siphene sinokuthi senzeke ekugqobhozeni okunqamlezayo, kwaye inxulumene ngokusondeleyo nokusebenza kwetyhubhu engenanto, ukulungiswa kwemilinganiselo yenkqubo yokugqobhoza yomatshini wokudlula, kunye nomgangatho wokugqobhoza. iplagi. Izinto ezichaphazela i-capillary infolding: enye kukunciphisa (izinga) kunye namaxesha oxinzelelo phambi kweplagi; enye yimilo yomngxuma; eyesithathu ngumgangatho womphezulu weplagi.
Ukugoba kwangaphandle kwetyhubhu ye-capillary: Ubuninzi bokugoba kwangaphandle kwetyhubhu ye-capillary kubangelwa yintsilelo yomhlaba we-tube blank, enye impazamo yomgangatho ophezulu obangelwa lula xa i-tube blank igqitywe kwaye ihlatywe. Izinto ezichaphazela ukugoba kwe-capillary ngaphandle: A. ityhubhu yeplastiki engenanto kunye ne-perforation deformation; B. iziphene zetyhubhu ezingenanto; C. umgangatho wesixhobo sokugqobhoza kunye nemilo yokupasa.

Ubunzima bodonga lwe-capillary olungalinganiyo: Kukho ukutyeba okungalinganiyo kodonga olunqamlezileyo kunye nobukhulu obungalinganiyo bodonga lobude. Xa kuqengqeleka kunye nokugqojozwa, ubukhulu bodonga olungalinganiyo olunqamlezayo bunokwenzeka kakhulu. Izinto eziphambili ezichaphazela ubungakanani obungalinganiyo bodonga lwetyhubhu ye-capillary yile: ubushushu bokufudumala kwetyhubhu engenanto, i-centering ye-tube end, ukulungiswa kwepateni yomngxuma womatshini wokubhoboza kunye nokumila kwesixhobo, njl.

Imikrwelo yomphezulu weCapillary: Nangona iimfuno zomgangatho womphezulu wemibhobho yecapillary enemingxuma ingangqongqo njengeemibhobho yokusila kunye nemilinganiselo yomgangatho womphezulu wombhobho wentsimbi, imikrwelo eqatha yomphezulu womphezulu wemibhobho yecapillary nayo iya kuchaphazela umgangatho womphezulu wemibhobho yentsimbi. Izinto ezichaphazela umphezulu we-abrasion ye-tube ye-capillary: ngokukodwa ngenxa yokuba umphezulu wesixhobo sokubhoboza okanye itafile yokuphuma yomshini wokubhoboza igugile kakhulu, i-rough okanye i-roller table ayijikelezi. Ukuze kuthintelwe umphezulu we-capillary ukuba uhlanjululwe yiziphene zomhlaba wesixhobo se-perforating, ukuhlolwa kunye nokugaya isixhobo sokugaya (i-cylinder kunye ne-trough) kufuneka kuqiniswe.
