1. Iithumbu leshawayinxalenye edibanisa ishawa kunye netephu. Amanzi aphuma kwishawari ashushu okanye abandayo, ngoko ke iimfuno zezinto eziphathekayo ziphezulu. Ngokuqhelekileyo, i-hose yenziwe ityhubhu yangaphakathi kunye netyhubhu yangaphandle. Izinto eziphathekayo zombhobho wangaphakathi zikhethwa kakhulu i-rubber ye-EPDM, kwaye izinto ze-tube yangaphandle zikhethwa yi-304 yensimbi engenasici. Umbhobho weshawari owenziwe ngale ndlela uya kugqama ngakumbi kwimidlalo eyahlukeneyo, ube nobomi obude benkonzo, kunye neshawa.
Amava nawo angcono. Enye iyakwazi ukumelana nokwaluphala nobushushu, kanti enye iyalastiki.
2. Ukumelana nokuguga kunye nokuchasana nobushushu kubalaseleyo. Oku kungenxa yokuba ukusebenza kwe-rubber ye-EPDM esetyenziswe kwi-tube yangaphakathi i-asidi kunye nokuchasana kwe-alkali, ukumelana nobushushu, kunokumelana nokucwiliswa kwamanzi ashushu ngaphezu kwe-100 degrees Celsius, kwaye ayihambelani nokwandiswa kunye nokuguqulwa. Iithumbu leshawaidinga amanzi ashushu ukuba ihambe ixesha elide ngexesha lokuhlambela, ngoko ke le mpahla yeyona nto ifanelekileyo yetyhubhu yangaphakathi.
3. Irabha ye-EPDM ine-elasticity engcono. Ngokuqhelekileyo kuyimfuneko yokwelula i-hose kwishawa ukuze kuhlanjwe ngcono. Kwenzeka nje ukuba izinto zerubha ze-EPDM zinokuguquguquka okungcono kwaye aziyi kuphazamiseka ngokutsala. Kulula ukubuyela kwimeko yokuqala kwaye ifanelekile ukusetyenziswa kweshawa. Esi sesinye sezizathu zokuba i-rubber ye-EPDM isetyenziswe.
4. Xa kuthengwa aithumbu leshawa, unokujonga kwangaphambili ukuqina kwe-hose ngokuzolula. Xa usoluliwe, ngcono i-elasticity, ingcono umgangatho werabha esetyenzisiweyo. Ukuze ukhuseleke ngcono ityhubhu yangaphakathi yerabha, ngokuqhelekileyo kukho i-nylon core eyenziwe ngeplastiki efakwe i-acrylic.
5. I-tube yangaphandle ye-304 yensimbi engenasici ikhusela ityhubhu yangaphakathi. Yenziwe ngokujija ucingo lwensimbi engenasici, olunokuthi luthintele uluhlu olunwebekayo lwetyhubhu yangaphakathi kunye nokuthintela ukuqhuma. Ukuze kuncitshiswe iindleko, abanye abavelisi basebenzisa isinyithi esingenasici endaweni yensimbi engenasici. Zinokolulwa ngexesha lokuthenga kwaye emva koko zivavanywe ukubona ukuba ziya kuphila na. Ukuba insimbi engenasici, iya kubuyela kwindawo yokuqala.
