Unokukhetha njani umgangatho woxinzelelo lombhobho we-UPVC?

Ukukhetha umbhobho wePlastiki we-UPVC kufuneka ucinge kuphela ngoxinzelelo lwegama lombhobho ngokwawo kodwa kunye nokusetyenziswa okuyinyani kombhobho wokusebenza koxinzelelo. Ukusetyenziswa kwangempela kombhobho we-UPVC ekusebenzeni koxinzelelo lwesando samanzi kuya kuveliswa. Ke ngoko, ukuqinisekisa ukusebenza ngokukhuselekileyo kombhobho, kuyimfuneko ukuqonda ingqikelelo yoxinzelelo olungentla, njengoko sikhetha umbhobho kwaye siyila isiseko soxinzelelo lwemibhobho, siya kwazisa ingcamango yoxinzelelo lweplastiki yombhobho we-UPVC embalwa:

01 Uxinzelelo lwegama: uxinzelelo oluphezulu lomsebenzi wombhobho xa uhambisa i-medium kwi-20 ℃, ekwanguxinzelelo oluqhelekileyo oluprintiweyo kumphezulu wombhobho.

I-02 Uxinzelelo lokusebenza: ubuninzi boxinzelelo lwamanzi oluqhubekayo olusebenza kudonga lwangaphakathi lombhobho phantsi kwemeko eqhelekileyo yokusebenza, ngaphandle koxinzelelo lwesando samanzi.

I-03 yoxinzelelo lwesando samanzi: umsebenzi wenkqubo yemibhobho, ngenxa yotshintsho olukhawulezayo lwesantya sokuhamba kwamanzi, kunye nokuguquguquka okukhawulezileyo koxinzelelo.

Uxinzelelo loyilo lwe-04: Ngexesha lenkqubo yokubhobhoza ukusebenza, uxinzelelo oluphezulu olukhawulezayo olusebenza eludongeni lwangaphakathi lombhobho, ngumbhobho oqhubekayo woxinzelelo osebenzayo kunye nesixa soxinzelelo lwesando samanzi.

Unokukhetha njani inqanaba loxinzelelo lombhobho we-UPVC?

Emva koko sisekukhethweni kombhobho, ukubhekisela kwimiba engasentla ngexesha elifanayo kufuneka kudibaniswe nesicelo sangempela, unokubhekisela kwifomula elandelayo ukukhetha inqanaba loxinzelelo lombhobho, njengoko kuchazwe ngezantsi:

Ukukhethwa kwinqanaba loxinzelelo lombhobho = uxinzelelo olusebenzayo lombhobho + malunga ne-0.3MPa yoxinzelelo lwehamile yamanzi + 0.1∽0.2MPa umda wokhuseleko.

Umzekelo: umbhobho wokusebenza koxinzelelo lwe-0.4MPa, kufuneka ukhethe ukuba yeyiphi inqanaba loxinzelelo lombhobho?

Indlela yokubala ngolu hlobo lulandelayo:

a. Sebenzisa uxinzelelo = 0.4MPa

b. Uxinzelelo lwehamile yamanzi = 0.3MPa

c. Ukhuseleko factor = 0.1-0.2MPa

d. Umlinganiselo woxinzelelo = 0.4 + 0.3 + 0.1 = 0.8MPa

Isiphelo: Umbhobho ngoxinzelelo lwegama le-0.8MPa okanye ngaphezulu kufuneka ukhethwe.

Wonke umntu ekukhetheni umbhobho kuqala ukuqonda ingcamango yoxinzelelo olungentla ngokweenkcukacha, kwaye emva koko isekelwe kwimo yesicelo esingqongileyo, sithathele ingqalelo ngokupheleleyo imiba yokhuseleko ekusebenzeni kombhobho, njengempembelelo yolwelo. iqondo lokushisa kunye nemida yokhuseleko, njl njl kukhetho oluchanekileyo lombhobho weplastiki ohambelana nenqanaba loxinzelelo, ukwenzela ukuba kuqinisekiswe ukusebenza ngokukhuselekileyo kombhobho.
