Ipayipi Elihlanganisiwe Le-Polyurethane (PU) Plastic-Reinforced Spiral Corrugated Hose liyipayipi elisebenza kahle kakhulu, elinezinjongo eziningi elenzelwe ukuhlangabezana nezidingo ezinzima zemisebenzi yezimboni, yezentengiselwano, neyezolimo. Isakhiwo salo esiyinhloko sihlanganisa udonga lwangaphakathi lwe-PU olubushelelezi, olungagugi kanye nokuqinisa okuhlanganisiwe kwepulasitiki okujikelezayo (noma ucingo lwensimbi olufakwe ithusi oluzikhethela ukuhlakazeka okungaguquki), okuletha ibhalansi engenakuqhathaniswa yokuguquguquka, amandla, kanye nokuqina.
Okokuqala, ukwakheka kwezinto zayo kuqinisekisa ubude obude obungavamile: ipayipi le-PU (elisekelwe ku-polyester) liqhosha ngokuqina kwe-Shore A okungu-95±2, okunikeza ukumelana okuphezulu kokuklwebheka, ukudabuka, kanye nokushayisana—okusebenza kahle kakhulu kunezinye izindlela zerabha noma ze-PVC ngezikhathi ezingu-3-5 ezimweni ezigugile kakhulu (isb., ukudlulisa izinto ezihlanganisiwe njengesamente noma okusanhlamvu). Ukuqina kwepulasitiki okujikelezayo kuqeda isidingo sezintambo zensimbi esindayo (ngaphandle kokuthi kuchazwe) ngenkathi kugcinwa ubuqotho besakhiwo, okuvumela ipayipi ukuthi imelane nokucindezela okuhle kufika kumabha ayi-10 kanye nokucindezela okungekuhle (ukumunca) kwebha engu-0.9, okwenza ifaneleke kokubili ukulethwa kanye nokuphathwa kwezinto ezisekelwe ku-vacuum.
Okwesibili, inikeza ukuzivumelanisa nezimo okubanzi kwemvelo: isebenza ngokwethembeka emazingeni okushisa asukela ku--40°C kuya ku-90°C (ngokubekezelela isikhathi esifushane kufika ku-120°C), ihlala iguquguquka ngisho nasemakhazeni amakhulu (ngokungafani namapayipi e-PVC aqinile) futhi imelana nokuguquguquka ezindaweni ezishisa kakhulu. Ngaphezu kwalokho, inguqulo yezinga lokudla (ehambisana nezindinganiso ze-EU 10/2011 kanye ne-FDA) ayinayo i-phthalates, i-BPA, kanye nezinsimbi ezisindayo, okwenza iphephe ekudluliseni uketshezi oludliwayo (amajusi, iwayini, ubisi) noma izithako zokudla ezomile—ezibalulekile ekucutshungulweni kokudla nasekukhiqizweni kweziphuzo. Ekusetshenzisweni kwezimboni, ibonisa ukumelana okuhle kwamakhemikhali namafutha, ama-asidi amnene, ama-alkali, kanye nezinyibilikisi, igwema ukuwohloka ezimweni zokusebenza ezinzima.
Okwesithathu, ukwakheka kwayo okugxile kumsebenzisi kuthuthukisa ukusebenza kahle: udonga lwangaphakathi olubushelelezi kakhulu (i-Ra < 0.5 μm) lunciphisa ukulahleka kokungqubuzana, luqinisekisa ukugeleza koketshezi, izimpushana, noma amagesi okungavinjelwe ngenkathi luvimbela ukwakheka kwezinsalela (okwenza kube lula ukuhlanza nokunciphisa izindleko zokulungisa). Ukwakhiwa okulula (≈30% kube lula kunamapayipi enjoloba anobubanzi obufanayo) kanye nesakhiwo esijikelezayo esingamelani nokugoba kuvumela ukujika okulula, ukugoba, kanye nokugoba—kulungile ezindaweni eziqinile (isb., umoya womshini, izingxenye zenjini yemikhumbi) noma izinhlelo zokusebenza zeselula (isb., izifutho zezolimo, amaphampu endawo yokwakha). Osayizi abangenziwa ngezifiso (ububanzi bangaphakathi: 25mm–300mm; ukujiya kodonga: 0.6mm–2mm) kanye nezinketho zombala (ezibonakalayo, ezimnyama, noma ezenziwe ngokwezifiso) zivumelana nezidingo ezithile, kusukela ekudlulisweni koketshezi lwelabhorethri oluncane kuya ekuthuthweni kwe-slurry yezimayini enkulu.
Okokugcina, ukuguquguquka kwayo kudlula izimboni: kwezolimo, isebenza njengemigqa yokunisela noma amapayipi okufutha/okukhipha iphampu; ekukhiqizeni, isebenza njengemigudu yokungenisa umoya yemishini yezindwangu noma amapayipi okuqoqa uthuli emishini yokupholisha insimbi; ekucubunguleni ukudla, idlulisela izithako phakathi kwezigaba zokukhiqiza; kanti ekumbeni, iphatha izinhlayiya ze-ore ezihuquzelayo. Izinguqulo ezingakhethwa zokuhlakazeka kwe-static (ezinokuqinisa ucingo lwensimbi olusekelwe phansi, ukumelana < 10² ohm/m) zengeza ukuphepha kokudluliselwa kwezinto ezivuthayo, kunciphisa ingozi yokukhishwa kwe-electrostatic.
Ngamafuphi, leli payipi lihlanganisa ukusebenza okuqinile, ukuhambisana nokuhlanzeka, kanye nokuguquguquka kokusebenza—okwenza kube yisisombululo esingabizi kakhulu nesihlala isikhathi eside sezinselele ezahlukahlukene zokuphatha izinto.
