Umbhobho we-HDPE wokubonelela ngamanzi okusela
Iimpawu zeMveliso
1. Ucoceko nokhuseleko
Ihambelana nomgangatho wococeko lwamanzi okusela we-GB/T 17219, ayinatyhefu kwaye ayinazo izongezo zesinyithi esinzima, ithintela ungcoliseko lwesibini.
2. Iguquguqukayo kwaye ilula
Uyilo lwekhoyili lulungele ukuthuthwa nokubekwa, kwaye lufanelekile ngokukodwa kubonelelo lwamanzi oluncinci (DN20-DN63) okanye ukunkcenkceshela okumiselweyo
3. Ukumelana nokugqwala kunye nokumelana nobushushu obuphantsi
Ayimelani nokugqwala okuphakathi kweekhemikhali, uluhlu lobushushu olufanelekileyo: -20℃ ukuya kwi-40℃ (ezinye iimodeli ze-HDPE zinokwandiswa ukuya kwi -60℃ ukuya kwi-60℃)
Imizekelo ephambili yokusetyenziswa
Ubonelelo lwamanzi kumakhaya nakuluntu: Ukuhanjiswa kwamanzi okusela kwisiphelo sendlela, njengeenkqubo zokucoca amanzi emakhaya kunye nemibhobho yamanzi okusela ngqo kwiindawo zokuhlala
Ukunkcenkceshela ngamaconsi ezolimo/i-micro-sprinkler: Iikhoyili ezincinci zifanelekile kwiisebe zeteyiphu zokunkcenkceshela ngamaconsi okanye kwiinkqubo ze-micro-sprinkler ze-greenhouse
Ubonelelo lwamanzi olungxamisekileyo: Imibhobho yamanzi okusela yexeshana esetyenziswa ngokukhawuleza (njengakwiimeko zokunceda xa kukho intlekele)
Amanqaku aPhambili oKhetho kunye noKwakha
1. Ukukhetha izinto
I-HDPE (udidi lwe-PE100) ikhethwa kakhulu kuba inamandla aphezulu kwaye inokumelana noxinzelelo oluhle kakhulu (ukuya kuthi ga kwi-1.6MPa).
2. Ukuchongwa komgangatho
Jonga ukuba imbonakalo igudile na ngaphandle kwamaqamza kwaye umbala uyafana (umnyama unekhabhoni emnyama yokumelana ne-UV, kwaye umhlophe ngumbala wendalo).
3. Indlela yoqhagamshelo
Kwi-DN≤63mm, i-hot-melt socket okanye uqhagamshelo lwe-electrofusion luyamkelwa ukuqinisekisa ukutywinwa kwe-interface
Iinkcukacha eziqhelekileyo
Ububanzi: DN20, DN25, DN32, DN40, DN50, DN63
Ubude bekhoyili: Ngokwesiqhelo iimitha ezingama-200 ngekhoyili nganye, enokulungiseka ngokwezifiso
