Sithi sithi amapayipi okungcono akhethe ukufudumeza nokuhanjiswa kwamanzi.
Ipayipi lakudala lensimbi kancane kancane lingena emlandweni, linikeze indlela yokuhlala isikhathi eside sanamuhla, kanye nama-analog angabizi kakhulu. Njengasezinto ezibonakalayo zokwakha ngasinye, zinezinzuzo zazo noma ezimbi. Ukukhetha amashubhu we-polypropylene, ubukhulu budinga ukubhekwa ngokucophelela nokwazi izici zokulebula. Thatha ngakho futhi ukhulume.
Konke okudingeka ukwazi mayelana nama-polypropylene amashubhu

Ukubukisisa
Okokuqala, kubalulekile ukwazi ububanzi bezakhi ze-poypropylene zokuhlinzekwa kwamanzi nokushisa. Kunezinhlobonhlobo eziningana, zihlukaniswe ngobukhulu odongeni, ukubalwa kwe-hydraulic kanye nombuso wokushisa, okwazi ukumelana.
- I-PN 10 - banezindonga ezincanyana kakhulu, okusho ukuthi kungcono ukungazi ukuthi ungazivivinyi ngamanzi ashisayo nokusetshenziswa kwamanzi abandayo. Kwesinye isikhathi bayasetshenziswa lapho befaka phansi okufudumele. Imikhiqizo enokumaka i-PN 10 ingamelana nokushisa kwamanzi ngokuphepha kuze kube ngama-45 degrees kanye nengcindezi enkulu ye-1 MPA.
- I-PN 16 iyingcindezi ephikelela kakhudlwana, esebenza ngokufika ku-1.6 MPA, kanye nokushisa kwamanzi okunconywayo ku-60 ° C.
- I-PN 20 - Njengoba ukushuba kodonga kwanda, izinkomba zokukhuthazela ziyakhula. Lapha ungahlela ama-degree afinyelela kuma-80 wokushisa emanzini bese uvivinya ingcindezi ye-2 MPA.
- I-PN 25 iyindlela ehlala isikhathi eside kunazo zonke. Ama-degree angama-95 acishe anamanzi abilayo agcinwe, kanye nokusebenza ngokuzola ngengcindezi ye-MPA engu-2,5.
Ngaphezu kwalezi zinkomba, kuyisiko ukuhlukanisa izakhiwo kungqimba olulodwa kanye ne-multilayer. Inketho yesibili ifakwe nge-fiberglass, foil kanye ne-basalt fiber. Kungani ukudinga? Ungqimba oluqinisayo kunokuba, empeleni, zonke lezi zithangezo zivumela izindonga ukuba zihlala isikhathi eside, ngakho-ke ukubekezelela izinkomba eziphakeme zokucindezela, amaconsi okushisa. Ingozi yokwandisa usayizi wamanzi ashisayo incishisiwe, okuvame ukwenzeka lapho usebenza nge-polypropylene.
Ungabi nephutha lapho ukhetha usayizi
Yini okudingeka uyazi, ukuya esitolo sokwakha izimpahla? Ukuqala - izimo zokusebenza. Ngabe lokhu kufakwa kwamanzi azokuthola ngamanzi okuphuza? Noma uhlela ukufudumeza, noma phansi okufudumele? Ngikholwe, kuzo zonke lezi zimo zamacala, usayizi wokufakelwa kwamapayipi e-polypropylene ku-MM uzohluka. Kungakho izakhi zithengwa ngaphansi komsebenzi othile wokwakha. Ngaphezu komsebenzi oyisisekelo, kuyadingeka ukubheka ukuthi ngabe kukhona ukufudumala egumbini lapho ukufakwa kuzokwenziwa khona.
Izici nokusebenzisa izinketho
Ukuthola ngokushesha okudingayo, kungcono ukubhekisa etafuleni lamapayipi e-polypropylene. Lapho, udinga ukuthola izinga lokushisa lenzalo, ubukhulu bokumakwa okuhambelana nezinkomba ezifiselekayo kuzoba umhlahlandlela wakho.Ubukhulu bePolypropylene Pipes kuma-Iches kanye ne-mm buchaziwe - lokhu kwenziwa ukuze kube lula, ngoba abakhiqizi bamazwe ahlukene banezincwadi zabo.
Izinketho zomkhiqizo ngokuya ngezici zokusebenzisa
- I-RRN - I-Homopolyymers, kufanelekile ukusebenzisa amanzi abandayo kuphela.
- I-RRV - ama-copolymers avinjelwe, nawo alungele amanzi abandayo, kwesinye isikhathi asasetshenziswa lapho ufaka phansi okufudumele.
- I-PPR yi-polypropylene copolymer, ukubukeka okuthandwa kakhulu, kungaxhumana namanzi ashisayo, abandayo, phansi okufudumele noma ukufudumala.
- I-PPS iyindlela ethuthukisiwe enokumelana okuphezulu okuphezulu. Kutholakala kaningi ezakhiweni ezifuywayo.
Ithebula lamapayipi e-polypropylene lokushisa nokuhanjiswa kwamanzi

Ukubeka ukuhanjiswa kwamanzi ngamanzi abandayo, kufaka phakathi ukuphuza, imikhiqizo emincane enobuhle nge-PN10 yokumaka i-PN10. Ipayipi lasekhaya alinazo izindawo eziphakeme zokucindezela, njengomthetho, alikhulu kune-1 MPA, kanti izinga lokushisa lamanzi eliphansi alibangeli ukwanda okuqondile.
Amapayipi e-polypropylene wokushisa, osayizi bawo abasetafuleni elingenhla, kuyinto efiselekayo ukuthi basebenzise ukuqiniswa nge-foil noma i-basalt. Lesi sakamuva savela muva nje emakethe futhi bakhona abantu abasebenza naye, kepha lokho sekuvele kunezibuyekezo ezinhle. Kungani ngidinga ukuqiniswa? Le yingxenye ebaluleke kakhulu ekwakhekeni kwamanzi ashisayo, ngoba ngenxa ye-gasket lapho kuvezwa ekushiseni okuphezulu, i-propylene ayishintshi ukwakheka nosayizi wayo. Futhi kusho ukuthi ngeke kube khona deformation ongadala ukuvuza. Ububanzi obungaphakathi bamapayipi e-polypropylene, itafula elivezwa ngenhla, liba ngaphansi, kepha imininingwane ihlala ingashintshiwe.
Imithetho namathiphu wokufaka awusizo
- Umklamo olula kakhulu ungqimba olulodwa. Ukubamisa, okokuqala umkhiqizo unqunywe ngabasiki bepayipi, baphendule imiphetho futhi bahlanganise design besebenzisa ukufakwa noma ukugcwaliswa.
- I-Multilayer ifakwe kanye nomehluko kuphela - lapho usebenza nabo ngeke kusetshenziswe i-welding ebandayo, ngeke inikeze ukuxhumana kuzo zonke izingqimba. Imvamisa, izingxenye ezahlukahlukene zixhumeke ngokushisa okushisayo noma zisebenzise ukufakwa okukhethekile.
- Amapayipi okuqinisa adinga ukulungiswa okukhethekile ngaphambi kokufakwa. Le nto ukuthi i-aluminium foil inamathele ku-fiber ku-glue, okusho ukuthi kunengozi ethile yokukhonkotha. Ukuze ugweme lokhu, ngaphambi kokufudumeza umkhiqizo ngokuqiniswa kwe-aluminium foil, kuyadingeka ukusindisa iziphetho ukuze ususe ingxenye ye-foil kusuka emaphethelweni, bese kuthi-ke i-fiber ezinhlangothini zombili. Ngokuvikelwa okunjalo, amanzi ngeke angene, okusho ukuthi ipayipi lizohlala linjengelinombolo.
Yini okufanele unake ukukhetha ukukhethwa
Njengomthetho, ukufakwa kwezingxenye zezingxenye ze-propelene kwenziwa nge-thermoplast. Lokhu okuqukethwe kuzwela kakhulu amaconsi okushisa futhi kungahle kuchithwe lapho kuvezwa ukushisa. Kungakho udinga ukukhetha izingxenye ngokunakekelwa okukhethekile. Ungayenzi kanjani iphutha?
- Ngamanzi ashisayo, ukufakwa kwezingcingo ngeke kuvumelane. Zikhubazekile lapho zicindezelwa futhi zingadala ukuqhekeka kwepayipi. Kungcono ukusebenzisa i-American - Indlela Ehlanganisiwe Ehlanganisiwe kalula, okusho ukuthi kuzoba lula kakhulu kuleli cala.
- Qiniseka ukuthi uhlola ukumaka nokugcina lapho uthenga umkhiqizo - kufanele kusondele ngokunembile kulo lonke umklamo. Isibonelo, uma usebenza ngokuthengisa, kubalulekile ukukhetha zombili imikhiqizo kusuka ezintweni ezifanayo.
- Ungathengi ukulungiswa okuguquliwe, okuchithiwe noma okuqhekekile. Izinto ezincane ongazithathi zingadala ukuwohloka kwawo wonke amanzi.
