Ma Valves a Mpira wa Port Yonse ndi Yochepetsedwa: Kusiyana Kofunikira ndi Buku Losankha
Ma valve a mpira ndi zinthu zofunika kwambiri mu makina owongolera madzi, omwe amagawidwa m'magulu awiri akuluakulu: doko lonse (bore lonse) ndi doko lochepetsedwa (bore lochepetsedwa). Kumvetsetsa kusiyana kwawo kumatsimikizira magwiridwe antchito abwino komanso kugwiritsa ntchito bwino ndalama m'mafakitale.
Kutanthauzira Ma Valves a Mpira wa Port Yonse ndi Ma Valves Ochepetsedwa a Port
-Vavu Yonse ya Mpira wa Port: M'mimba mwake wa valavuyo umafanana ndi ≥95% ya m'mimba mwake wa payipiyo (monga, valavu ya mainchesi awiri ili ndi njira yoyendera ya 50mm).
Malangizo: Mukasankha valavu ya mpira, valavu ya mpira ya full-bore 2 Inch imakhala ndi kukula kwa valavu kolembedwa ngati NPS 2.
- Valavu Yochepetsedwa ya Mpira wa Port: M'mimba mwake wamkati ndi ≤85% ya m'mimba mwake wa payipi (monga, valavu ya mainchesi awiri ili ndi njira yoyendera ya ~38mm).
Langizo: Mukasankha valavu ya mpira, valavu ya mpira ya 2 Inch yochepetsedwa imakhala ndi kukula kwa valavu yolembedwa ngati NPS 2 x 1-1/2.
Kusiyana Kwakukulu kwa Kapangidwe
| Mbali | Valavu Yonse ya Mpira | Valavu ya Mpira Yochepetsedwa |
|---|---|---|
| Kapangidwe ka Njira Yoyendera | Ofanana ndi m'mimba mwake wa payipi; palibe kuchepera | Masayizi 1-2 ocheperako kuposa payipi |
| Kugwira Ntchito Moyenera | Kuchepetsa kuyenda kwa madzi; kutsika kochepa kwa kuthamanga kwa magazi | Kukana kwakukulu kuposa kunyamula katundu wonse |
| Kukula kwa Vavu (NPS) | Matches pipeline (monga, NPS 2) | Kumatanthauza kuchepetsa (monga, NPS 2 × 1½) |
| Kulemera ndi Kufupika | Yolemera; yomanga yolimba | 30% yopepuka; kapangidwe kosunga malo |
Kuyerekeza Magwiridwe Antchito ndi Kugwiritsa Ntchito
| Factor | Valavu Yonse ya Mpira | Valavu ya Mpira Yochepetsedwa |
|---|---|---|
| Zanema Zabwino | Madzi okhuthala (mafuta osakonzedwa, matope), makina osungira nkhumba | Mpweya, madzi, madzi otsika kukhuthala |
| Zofunikira pa Kuyenda | Kuthamanga kwakukulu ndi kukana kochepa | Kuyenda kolamulidwa; mphamvu yosinthika |
| Milandu Yogwiritsidwa Ntchito Kawirikawiri | Mapaipi akuluakulu (mafuta/gasi), makina oyeretsera | Mizere ya nthambi, mapulojekiti okhudzana ndi bajeti |
| Kutsika kwa Kupanikizika | Kukana pafupifupi zero; yabwino kwambiri pamapaipi aatali | Kutsika kwakukulu kwa kuthamanga kwa magazi m'deralo |
| Kugwiritsa Ntchito Ndalama Moyenera | Mtengo wokwera pasadakhale | Mtengo wotsika ndi 30%; katundu wochepa wa mapaipi |
Momwe Mungasankhire Valavu Yabwino ya Mpira
Ikani patsogolo Full Bore Ngati:
1. Kugwira zinthu zokhuthala/zosalala kapena kufunikira kukumba.
2. Dongosolo limafuna kuyenda kwakukulu popanda kutayika kwakukulu kwa mphamvu.
3. Kuyeretsa/kukonza mapaipi ndi ntchito yachizolowezi.
Sankhani Kuchepetsa Bore Pamene:
1. Kugwira ntchito ndi mpweya kapena zakumwa zokhuthala pang'ono.
2. Pali zoletsa pa bajeti; ma valve opepuka ndi omwe amakondedwa.
3. Kulamulira kayendedwe ka madzi ndi kukonza malo ndikofunikira kwambiri.
Chifukwa Chake Ndi Chofunika
1. Ma Valves Odzaza ndi Bore amachotsa zoletsa kuyenda kwa madzi, zomwe zimachepetsa ndalama zamagetsi poyendetsa mtunda wautali.
2. Ma Vavu Ochepetsa Ma Bore amapereka ndalama zosungira (mpaka theka la mtengo) komanso njira yoyendetsera bwino kayendedwe ka madzi pamakompyuta ang'onoang'ono, pomwe amachepetsa katundu womangidwa pamapaipi.
