Umbhobho wetyhubhu oshushu oqengqelekayo
Umbhobho weNtsimbi oQhelekileyo oqengqelekayo
Iityhubhu zentsimbi ezingenamthungo ezishushu ezisongiweyo ziveliswa ngokubanzi kwiiyunithi zokuqengqeleka kombhobho.
I-tube eqinileyo engenanto ihlolwe kwaye iziphene zomhlaba ziyasuswa, zinqunywe ubude obufunekayo, zijoliswe ekupheleni kwe-perforated ye-tube engenanto, kwaye emva koko ithunyelwe kwisithando somlilo sokufudumeza kunye nokubhoboza kumatshini wokubhoboza.Iyaqhubeka ijikeleza kwaye iqhubela phambili ngexesha lokugqobhoza imingxuma.Ngaphantsi kweempembelelo ze-roller kunye nesiphelo, i-tube blank i-hollow ngokuthe ngcembe, ebizwa ngokuba yi-gross pipe.Emva koko ithunyelwa kumatshini wokuqengqeleka kombhobho ozenzekelayo ukuze uqhubeke nokuqengqeleka.Ekugqibeleni, ubukhulu bodonga bulinganiswe ngumatshini wokulinganisa, kwaye ububanzi buchongwa ngumatshini wokulinganisa ukuhlangabezana neemfuno ezicacileyo.Ukusetyenziswa kweeyunithi eziqhubekayo zokuqengqeleka kwemibhobho ukuvelisa imibhobho yentsimbi engenamthungo eshushu eqengqelekayo yindlela ephucukileyo.
Umbhobho wentsimbi oshushu oqengqelekayo ongenamthungo: ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukushenxiswa ityhubhu → ukucutha ubukhulu (okanye ukucutha ubukhulu) → ukupholisa → ityhubhu yebhiliti → ukolula → uvavanyo loxinzelelo lwamanzi (okanye ukufumanisa isiphene) →makisha→indawo yokugcina impahla
