Ungasarudza sei UPVC pombi kudzvanywa kwechiyero?

Kusarudza Plastiki UPVC pombi haifanire kufunga kwete chete kudzvanywa kwepombi pachayo asiwo kushandiswa chaiko kwepombi inoshanda kumanikidza. Iko kushandiswa kweiyo UPVC pombi mukushanda kwesando yemvura inomanikidza ichagadzirwa. Naizvozvo, kuti ive nechokwadi chekushanda kwakachengeteka kwepombi, zvinodikanwa kuti tinzwisise pfungwa yekumanikidza iri pamusoro, apo isu tichisarudza pombi nekugadzira iyo pombi yekumanikidza hwaro, isu tichaunza mashoma UPVC epurasitiki pombi yekumanikidza pfungwa:

01 Nominal pressure: iyo yakanyanya kushanda kumanikidza kwepombi kana ichiendesa svikiro pa20 ℃, iri zvakare kudzvanywa kunowanzo kudhindwa pamusoro pepombi.

02 Kushanda kudzvanywa: iyo yakanyanya kuenderera yekumanikidza yemvura inobata pamadziro emukati wepombi pasi peyakajairika mamiriro ekushanda, kusasanganisa mvura sando kumanikidza.

03 nyundo yemvura inomanikidza: piping system inoshanda, nekuda kwekuchinja kamwe kamwe mukuyerera kwemvura, uye nekukasira kushanduka kwekumanikidza.

04 dhizaini yedhizaini: Panguva yepiping system inoshanda, iyo yakanyanya kukurumidza kumanikidza inobata pamadziro emukati wepombi, ndiyo pombi inoenderera ichishanda kumanikidza uye huwandu hwemvura sando yekumanikidza.

Ungasarudza sei UPVC pombi yekumanikidza level?

Ipapo isu tiri mukusarudzwa kwepombi, kunongedzera kuzvinhu zviri pamusoro panguva imwe chete zvinofanirwa kusanganiswa neiyo chaiyo yekushandisa, unogona kutarisa kune inotevera fomula yekusarudza iyo pombi yekumanikidza level, sekutsanangurwa pazasi:

Kusarudzwa kwepombi pressure level = pombi inoshanda kudzvinyirirwa + inenge 0.3MPa mvura sando pressure + 0.1∽0.2MPa chengetedzo margin.

Muenzaniso: pombi inoshanda yekumanikidza ye0.4MPa, inofanirwa kusarudza kuti ndeipi yekumanikidza kwepombi?

Calculation nzira ndeiyi inotevera:

a. Shandisa kumanikidza = 0.4MPa

b. Sando yemvura inomanikidza = 0.3MPa

c. Safety factor = 0.1-0.2MPa

d. Chiyero chekumanikidza = 0.4 + 0.3 + 0.1 = 0.8MPa

Mhedziso: Pombi ine zita rekumanikidza ye0.8MPa kana kupfuura inofanira kusarudzwa.

Wese munhu ari musarudzo yepombi kutanga kwezvose kuti anzwisise pfungwa yekumanikidza iri pamusoro zvakadzama, uyezve zvichibva pane chaiyo yekushandisa nharaunda, tarisa zvizere kuchengetedza zvinhu mukushanda kwepombi, sekukanganisa kwemvura. tembiricha uye miganho yekudzivirira, nezvimwe kune kusarudzwa kwakaringana kwepombi yepurasitiki inoenderana nedanho rekumanikidza, kuitira kuve nechokwadi chekushanda kwakachengeteka kwepombi.
