Munzvimbo dzakasiyana-siyana dzakadai seinjiniya, kugadzira, uye kuvaka, izwi rekuti "nominal dhayamita" rinowanzo shandiswa kutsanangura saizi dzemapaipi, machubhu, nezvimwe zvinhu zvecylindrical. Kunzwisisa zvinoreva nominal dhayamita kwakakosha kune nyanzvi dzinoshandisa zvinhu izvi, sezvo zvichiita basa guru mukuona kuti zvinoenderana, zvinoshanda, uye zvakachengeteka mumabasa akasiyana-siyana.
Tsanangudzo yedhayamita rezita
Dhayamita yepakati (Nominal diameter) iyuniti yakajairwa yekuyera inoshandiswa kuratidza saizi inofungidzirwa yemapaipi kana machubhu. Haisi nzira chaiyo yekuyera, asi inzira iri nyore yekuisa muzvikamu nekuona saizi yezvinhu zvakaita secylindrical. Dhayamita yepakati inowanzo ratidzwa mumamirimita (mm) kana masendimita, zvichienderana nezvinodiwa munharaunda uye muindasitiri.
Semuenzaniso, pombi ine dhayamita ye50 mm inogona kunge isina dhayamita yekunze ye50 mm. Izvi zvinoreva kuti pombi yakagadzirirwa kushandiswa nezvimwe zvikamu zvehukuru hwakafanana. Sisitimu iyi yekuenzanisa zvinhu inobatsira kutaurirana nekugadzirwa kwezvinhu pakati pemainjiniya, vagadziri, uye makondirakiti.
Kukosha kweDhayamita Yemazita
Kushandisa dhayamita yezita kwakakosha nekuda kwezvikonzero zvinotevera:
1. Kuenzanisa: Kuisa mapaipi nemachubhu muzvikamu nedhayamita yepamusoro kunoita kuti zvive nyore kuvagadziri kugadzira nekutengesa zvigadzirwa. Kuenzanisa uku kunoitawo kuti nzira yekutenga ive nyore kune vanogadzira makondirakiti nemainjiniya, sezvo vachigona kuona zviri nyore zvinhu zvinoenderana nazvo.
2. Kuchinjana: Nekushandisa dhayamita dzinoshandiswa, vagadziri vakasiyana vanogona kugadzira mapaipi nemidziyo inochinjika. Izvi zvakakosha zvikuru muindasitiri yekuvaka nekugadzira mapaipi, sezvo zvikamu zvakasiyana-siyana zvichifanira kubatanidzwa zvakanaka kuti zvive nechokwadi chekuti sisitimu yacho yakavimbika.
3. Dhizaini neUinjiniya: Mainjiniya anoreva dhayamita dzemhando yepamusoro pakugadzira masisitimu ane chekuita nekuyerera kwemvura, rutsigiro rwechimiro, kana mamwe mashandisirwo. Kunzwisisa miganhu yemhando yepamusoro kunobatsira pakuverenga mwero wekuyerera kwemvura, kudzikira kwedzvinyiriro, nezvimwe zvinhu zvikuru zvinokanganisa mashandiro esisitimu.
4. Kushanda zvakanaka kwemari: Kushandisa dhayamita shoma kunogona kuchengetedza mari yekugadzira nekuvaka. Nekushandisa zviyero zvakajairwa, vagadziri vanogona kurerutsa maitiro ekugadzira, uye makondirakiti anogona kuderedza marara nekushandisa zvinhu zviripo zviri nyore.
Dhayamita yezita richienzaniswa nedhayamita chaiyo
Zvakakosha kuziva kuti dhayamita chaiyo nedhayamita chaiyo hazvina kufanana. Dhayamita chaiyo zvinoreva kuyera kwakarurama kwedhayamita yekunze kana yemukati yepombi kana chubhu. Semuenzaniso, pombi ine dhayamita chaiyo ye50 mm inogona kuva nedhayamita chaiyo yekunze ye60 mm uye dhayamita yemukati ye50 mm, zvichienderana nehukobvu hwemadziro. Kusiyanisa pakati pedhayamita chaiyo nedhayamita chaiyo kwakakosha kune mainjiniya nevanoita mabasa, sezvo kushandisa zviyero zvisirizvo kunogona kukonzera matambudziko ekubatana uye kutadza kushanda zvakanaka kwesystem.
Kushandiswa kwedhayamita yezita
Dhayamita yepakati inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, anosanganisira kupa mvura nekudhonza mvura, kudziyisa, kufefetedza mhepo nekutonhodza (HVAC), mafuta negesi, uye kuvaka. Semuenzaniso, mumasisitimu ekupa mvura nekudhonza mvura, dhayamita yepakati inobatsira kuona saizi dzakakodzera dzemapaipi. Mumasisitimu eHVAC, dhayamita yepakati inoshandiswa kuona saizi dzemapombi kuti mhepo ifambe zvakanaka.
Saka, dhayamita yemhando yepamusoro ipfungwa huru muinjiniya nekugadzira, zvichibatsira mukuongorora nekupatsanura zvinhu zvecylindrical. Nekunzwisisa zvinoreva dhayamita yemhando yepamusoro uye musiyano wayo kubva kudhayamita chaiyo, nyanzvi dzinogona kuve nechokwadi chekugadzirwa kwakanaka, kuvaka, uye kuchengetedza masisitimu akasiyana-siyana. Ingave iri mukugadzira mapaipi, kuvaka, kana chero imwe nzvimbo, kuziva kukosha kwedhayamita yemhando yepamusoro kwakakosha pakuita basa rakanaka uye kuchengetedzeka.
Kana muine mimwe mibvunzo, ndapota inzwa wakasununguka kutaura neKingflex Team.
