Ngobuchwephesha, kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhethaimibhobho yaselwandle, njenge: ubungakanani, uhlobo, kunye nezinto.Ngokwembono yesicelo, cUqwalaselo kufuneka lunikezelwe kwisitayile sokufakela, ukuhamba kunye noxinzelelo, iinkqubo zemibhobho, ubomi benkonzo, kunye nokumelana nomhlwa kunye nokudinwa.Ukongezelela, ubude kunye ne-radius yokugoba ye-hose nayo kufuneka ithathelwe ingqalelo ukuqinisekisa ukhuseleko nokuthembeka kwayokwiumbhobho.Xa ukhetha i-hose, zonke iimpawu zayo kufuneka ziqwalaselwe ngokubanzi.
Izinto eziphathekayo
Ungokwenene ezahlukeneyo izixhobo kunye neenkqubozisetyenziswangexesha lenkqubo yokuvelisaimibhobho yaselwandleukuhlangabezana neemfuno ezahlukeneyo zokusebenza.Okwangoku kukho iintlobo ngeentlobo zemathiriyeli kwimarike ezinokuthi zisetyenziswe ekuveliseni nasekuveliseni imibhobho yaselwandle, njengerabha yendalo (NR), irabha ye-butyl (SBR) kunye ne-polyurethane (PU).Ekubeni izinto ezahlukeneyo zineempawu ezahlukeneyo, ukuveliswa kwazo kunye neenkqubo zokuvelisa nazo zihluke.Ukuze kuqinisekiswe ukuveliswa kwee-hoses ezihlangabezana neemfuno, kuyimfuneko ukukhetha i-ma efanelekileyoizixhobo kunyeinkqubo yokuvelisa ngokweemfuno ezahlukeneyo zesicelo kunye neemeko zesicelo.
Ubungakanani
Ubungakanani yinto ebalulekileyo xa ukhetha imibhobho yaselwandle, kwaye ubungakanani bombhobho ofunekayo bunokwahluka kwizicelo ezahlukeneyo kunye nemidiya.I-CDSR inokubonelela ngeendlela ezahlukeneyo zokuchaza ngokweemfuno zabathengi kwaye iqinisekise ukuba i-hose ifanelekile kwiimeko ezahlukeneyo zesicelo.
● I-diameter yangaphakathi inefuthe elithe ngqo kwisantya sokuhamba kunye noxinzelelo lolwelo.I-diameter enkulu yangaphakathi inokubonelela ngokuhamba okukhulu, kodwa inokubangela ilahleko enkulu yoxinzelelo phantsi kweemeko zoxinzelelo oluphezulu.Ngoko ke, izinto ezifanelekileyo ze-hose kunye nobubanzi bangaphakathi kufuneka zikhethwe ngokusekelwe kwimeko ye-fluid ephathwayo kunye noxinzelelo olufunekayo lokusebenza.
● I-diameter yangaphandle inempembelelo kumandla omatshini kunye nokuqina kombhobho.I-diameter yangaphandle enkulu idla ngokunika amandla angcono omatshini kunye nokumelana nokunxiba.Kodwa kuya kwandisa ixabiso lokuqina kombhobho, ngaloo ndlela ukwandisa ubunzima bombhobho.Ngoko ke, i-diameter yangaphandle efanelekileyo kufuneka ithathelwe ingqalelo ngokusekelwe kwiimeko ezithile zokusingqongileyo kunye neemfuno zesicelo.
● Ubude bombhobho kufuneka bumiselwe ngokusekelwe kwiimfuno ezithile zokusetyenziswa.Umgama phakathi kwamanqaku amabini esiphelo soqhagamshelo lombhobho ngokunjalo nokukaleka kunye nokugoba iradiyasi yombhobho kufuneka kuthathelwe ingqalelo ukuqinisekisa ukuba ubude bombhobho banele ukuhlangabezana neemfuno zoyilo ezifana namandla emibhobho kunye nomgama wokhuseleko wokusebenza. .
Isicelo
Iimfuno zokusetyenziswa, iimeko zokusingqongileyo kunye nemigangatho yoshishino idlala indima ebalulekileyo ekuphuhliseni imveliso, ulawulo lweprojekthi, ulawulo lomgangatho, njl. Banceda ekuqinisekiseni ukuba iimveliso okanye iinkonzo zinokuhlangabezana neemfuno zabasebenzisi, zilungelelanise iimeko ezahlukeneyo zokusingqongileyo, kunye nokuthobela imigaqo kunye nemigangatho yoshishino.
Ngeqela layo lobuchwephesha lobuchwephesha, izixhobo zokuvelisa eziphambili kunye neminyaka yamava, i-CDSR iyakwazi ukubonelela abathengi ngezisombululo zehose yaselwandle ezilungiselelwe ukuhlangabezana neemfuno ezithile ezahlukeneyo.Qhagamshelana nathi namhlanje ukufumana iuProisisombululo sefessional kwiimfuno zakho zemibhobho yaselwandle!
