Ungakhetha kanjani isilinganiso sokucindezela kwepayipi le-UPVC?

Ukukhetha ipayipi lePlastiki le-UPVC akufanele licabangele ukucindezela okuzisholo kwepayipi ngokwayo kodwa futhi nokusetshenziswa kwangempela kwengcindezi yokusebenza kwepayipi. Ukusetshenziswa kwangempela kwepayipi le-UPVC ekusebenzeni kokucindezela kwesando samanzi kuzokwenziwa. Ngakho-ke, ukuze kuqinisekiswe ukusebenza okuphephile kwepayipi, kubalulekile ukuqonda umqondo wengcindezi engenhla, njengoba sikhetha ipayipi futhi siklama isisekelo sokucindezela kwepayipi, sizokwethula umqondo wokucindezela wepayipi lepulasitiki le-UPVC embalwa:

01 Ukucindezela okuzisholo: ukucindezela okuphezulu kokusebenza kwepayipi lapho udlulisa okuphakathi ku-20℃, okuphinde kube ingcindezi evame ukuphrintwa ebusweni bepayipi.

02 Ingcindezi yokusebenza: umfutho wamanzi omkhulu oqhubekayo osebenza odongeni lwangaphakathi lwepayipi ngaphansi kwesimo esivamile sokusebenza, ngaphandle kokucindezela kwesando samanzi.

I-03 ingcindezi yesando samanzi: ukusebenza kwesistimu yamapayipi, ngenxa yezinguquko ezisheshayo ezilinganisweni zokugeleza kwamanzi, kanye nokuguquguquka okusheshayo kwengcindezi.

04 ingcindezi yokuklama: Ngesikhathi sokusebenza kwesistimu yamapayipi, ingcindezi ephezulu esheshayo esebenza odongeni lwangaphakathi lwepayipi, ipayipi lokucindezela okuqhubekayo kokusebenza kanye nesamba sokucindezela kwesando samanzi.

Ungakhetha kanjani izinga lokucindezela kwepayipi le-UPVC?

Khona-ke sisekukhethweni kwepayipi, ireferensi yezici ezingenhla ngesikhathi esifanayo kufanele futhi ihlanganiswe nesicelo sangempela, ungabhekisela kufomula elandelayo ukuze ukhethe izinga lokucindezela kwepayipi, njengoba kuchazwe ngezansi:

Ukukhethwa kwezinga lomfutho wepayipi = ingcindezi yokusebenza yepayipi + cishe u-0.3MPa umfutho wesando samanzi + 0.1∽0.2MPa imajini yokuphepha.

Isibonelo: umfutho wokusebenza kwepayipi ongu-0.4MPa, kufanele ukhethe ukuthi yiliphi izinga lomfutho wepayipi?

Indlela yokubala imi kanje:

a. Sebenzisa ingcindezi = 0.4MPa

b. Umfutho wesando samanzi = 0.3MPa

c. Isici sokuphepha = 0.1-0.2MPa

d. Isilinganiso sokucindezela = 0.4 + 0.3 + 0.1 = 0.8MPa

Isiphetho: Ipayipi elinengcindezi encane engu-0.8MPa noma ngaphezulu kufanele ikhethwe.

Wonke umuntu okhethweni lwepayipi okokuqala nje ukuqonda umqondo wengcindezi engenhla ngokuningiliziwe, bese ngokusekelwe endaweni yangempela yohlelo lokusebenza, acabangele ngokugcwele izici zokuphepha ekusebenzeni kwepayipi, njengomthelela woketshezi. izinga lokushisa kanye nemingcele yokuphepha, njll ekukhethweni okulungile kwepayipi lepulasitiki elihambisana nezinga lokucindezela, ukuze kuqinisekiswe ukusebenza okuphephile kwepayipi.
