Munzvimbo dzakasiyana siyana senge engineering, kugadzira, uye kuvaka, izwi rekuti "zita rekuti dhayamita" rinowanzoshandiswa kutsanangura zviyero zvepombi, tubing, uye zvimwe zvinhu zvecylindrical. Kunzwisisa zvinorehwa nedhayamita yezita kwakakosha kune nyanzvi dzinoshandisa zvinhu izvi, sezvo ichiita basa rakakosha mukuona kuenderana, kuita, uye kuchengetedzeka mumhando dzakasiyana dzekushandisa.
Tsanangudzo yeNominal Diameter
Zita dhayamita ichikamu chakamisikidzwa chechiyero chinoshandiswa kutaridza hukuru hwemapombi kana tubing. Haisi kuyerwa chaiko, asi inzira iri nyore yekuisa mumapoka uye kuona zviyero zvecylindrical zvinhu. Zita dhayamita rinowanzoratidzwa mumamirimita (mm) kana inches, zvichienderana nematunhu uye indasitiri zviyero.
Semuenzaniso, pombi ine dhayamita yezita re50 mm inogona kunge isina dhayamita yekunze ye50 mm. Izvi zvinoreva kuti pombi yakagadzirirwa kushandiswa nezvimwe zvikamu zvehukuru hwezita. Iyi dimensionaling system inofambisa kutaurirana uye kutsanangurwa kwekusimudzira pakati peinjiniya, vagadziri, uye makondirakiti.
Kukosha kweNominal Diameter
Kushandisa dhayamita yezita kwakakosha nekuda kwezvikonzero zvinotevera:
1. Kumira: Kuronga mapaipi uye tubing nedhayamita yezita inopa nzira yakarongeka, zvichiita kuti zvive nyore kune vanogadzira kugadzira uye kutengesa zvigadzirwa. Uku kumisikidza zvakare kunorerutsa maitiro ekutenga kune makondirakiti uye mainjiniya, sezvo vachigona kuona zviri nyore zvinhu zvinoenderana.
2. Kuchinjana: Nokushandisa mazita madhayamita, vagadziri vakasiyana vanogona kugadzira mapaipi anochinja uye mafittings. Izvi zvinonyanya kukosha mumaindasitiri ekuvaka uye epombi dzemvura, sezvo zvikamu zvakasiyana-siyana zvinofanirwa kunge zvakabatanidzwa zvisina musono kuti ive nechokwadi chekuvimbika kwehurongwa.
3. Dhizaini neUinjiniya: Mainjiniya anoreva mazita emadhayamita pavanenge vachigadzira masisitimu anosanganisira kuyerera kwemvura, tsigiro yezvimiro, kana mamwe maapplication. Kunzwisisa zvimiro zvezita kunobatsira mukuverenga kuyerera kwemazinga, kudonhedza kudonha, uye zvimwe zvakakosha zvinokanganisa mashandiro ehurongwa.
4. Mutengo-kubudirira: Kushandisa mazita madhayamita kunogona kuchengetedza pakugadzira uye kuvaka mari. Nekutora zviyero zvakamisikidzwa, vagadziri vanogona kukwenenzvera maitiro ekugadzira, uye makondirakiti anogona kuderedza marara nekushandisa zvinowanika zviri nyore.
Zita dhayamita vs. dhayamita chairo
Zvakakosha kucherechedza kuti zita rezita uye dhayamita chaiyo hazvina kufanana. Chaiyo dhayamita inoreva kuyerwa chaiko kwedhayamita rekunze kana remukati repombi kana tubing. Semuenzaniso, pombi ine dhayamita yezita re 50 mm inogona kunge iine dhayamita chaiyo yekunze ye60 mm uye dhayamita yemukati ye50 mm, zvichienderana nekukora kwemadziro. Kusiyanisa pakati pezita uye dhayamita chaiyo kwakakosha kune mainjiniya nemakondirakiti, sezvo kushandisa zviyero zvisirizvo kunogona kutungamirira kunyaya dzekuenderana uye kusashanda zvakanaka kwehurongwa.
Kushandiswa kweNominal Diameter
Zita dhayamita rinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira mvura uye dhiraivha, kudziyisa, kufefetedza nemhepo (HVAC), oiri negesi, uye kuvaka. Semuenzaniso, mumvura yekupa uye madhiraini masisitimu, zita rekuti dhayamita rinobatsira kuona akakodzera pombi saizi. MuHVAC masisitimu, dhayamita yezita rinoshandiswa kuona saizi dzema duct kuti uwane mafambiro emhepo.
Saka, dhayamita yezita ipfungwa yakakosha muinjiniya nekugadzira, ichibatsira muchikamu uye kuenderana ongororo yezvinhu zvecylindrical. Nekunzwisisa zvinorehwa nedhayamita yezita uye mutsauko waro kubva padhayamita chaiyo, nyanzvi dzinogona kuve nechokwadi dhizaini yakatsetseka, kuvaka, uye kugadzirisa masisitimu akasiyana. Zvingave mupombi, kuvaka, kana chero imwe nzvimbo, kuziva kukosha kwedhayamita yezita kwakakosha kuti uwane kuita kwakaringana uye kuchengetedzeka.
Kana iwe uine mumwe mubvunzo, ndapota inzwa wakasununguka kubata neKingflex Team.
