Mavharuvhu Ebhora RemaPort Akazara: Nheyo Dzekugadzira, Kuverenga, uye Mashandisirwo Emaindasitiri
Dhayamita yenzira yekuyerera kwevharuvhu yebhora chinhu chakakosha pakushanda kwayo.mavharuvhu ebhora akazara echiteshi, chiyero ichi chinoratidza kushanda zvakanaka kwemvura, kurasikirwa nekumanikidzwa, uye kukodzera kwemaindasitiri anodiwa zvakanyanya. Heino maitiro ekugadzira nekushandisa zvinobudirira.
Vharuvhu Yebhora Yese Yechiteshi: Tsanangudzo & Nzira Dzekuverenga
1. Tsananguro Yepakati
Vharuvhu yebhora ine chiteshi chakazara (full bore) ine dhayamita yemugero wekuyerera inoenderana ne ≥95% yedhayamita yemukati mepaipi, zvichiita kuti kuyerera kurege kudzorwa nekuderedzwa kwekumanikidzwa kushoma.
2. Kuverenga Kunobva Pakuyerera
Shandisa fomura ye empirical fluid dynamics:
Q = K × Cv × √ΔP
Mubvunzo: Mwero wekuyerera kwemvura (GPM kana m³/h)
K: Chinhu chekugadzirisa (kazhinji 0.9)
Cv: Kuyerera kwemvura (kwakanangana nevharuvhu)
ΔP: Musiyano wekumanikidzwa (psi kana bhawa)
Fomura yedhayamita yebore rakabva:
d = (Q / (0.9 × Cv × √ΔP)) × 25.4
(d = dhayamita mu mm; 25.4 = kushandurwa kwe inch-mm)
3. Nzira pfupi yekukura kwepaipi
d = D × 0.8
d: Dhayamita yebhore revharuvhu
D: Dhayamita yekunze yepombi
Muenzaniso: Pamuchina we100mm OD, sarudza vharuvhu ine bore re ≥80mm.
Chiteshi Chizere vs Kuderedza Chiteshi: Misiyano Yakakosha
Paramita | Vharuvhu Yese Yechiteshi Chebhora | Deredza Port Ball Valve |
|---|---|---|
| Nzira Yekuyerera | Matches pombi ID (semuenzaniso, DN50 = 50mm) | Saizi 1-2 diki (semuenzaniso, DN50 ≈ 38mm) |
| Kushanda Zvakanaka Kwekuyerera | Kuramba kuri pedyo ne zero; kuyerera kwakazara | Kuderedzwa kwemvura ne15-30% |
| Kuderera kweDzvinyiriro | Hazvina basa | Zvakakosha pakuyerera kwakanyanya |
| Mashandisirwo | Zvakakosha pakunatsa nguruve, mvura inonamira | Masisitimu anoyerera zvishoma; mapurojekiti anodhura zvishoma |
Ruzivo Rukuru:
Vharuvhu yeDN50 yakazara inochengetedza kuyerera kwe50mm, nepo vharuvhu yeDN50 yekuderedza kuyerera kwemvura inoderedza kuyerera kwemvura kusvika ~DN40 (38mm) - kurasikirwa kwenzvimbo yekuyerera kwemvura ne24%.
Mashandisirwo Emaindasitiri: Kwakakwana Mavharuvhu ePort Excel
1. Mapaipi eOiri neGasi
Basa:Kudzima/kudzora tambo yetrunk
Zvakanakira:Inogonesa kugayiwa kwemapaipi kuti agadziriswe; inobata mafuta asina kucheneswa/tsvina isina kuvharika.
2. Kugadziriswa kweMakemikoro
Nyaya Yekushandisa:Mitsetse yekudyara reactor inoyerera zvakanyanya
Kubatsirwa:Inodzivirira zvirambidzo zvekuyerera kwemvura zvinokanganisa kuenderera mberi kwekugadzirwa.
3. Kutarisirwa kweMvura
Mashandisirwo:
1. Mapombi makuru emvura eguta
2. Nzvimbo dzekuchenesa mvura yetsvina
Chikonzero: Inowedzera kuyerera kwemvura panguva yekudiwa kwakanyanya.
Nhungamiro dzeSarudzo: Nguva Yekusarudza Full Port
Sarudza mavharuvhu akazara kana:
1.Kuyerera kwakakosha:Masisitimu anoda kurasikirwa kushoma kwekumanikidzwa (semuenzaniso, mapaipi ekufamba kure).
2. Midhiya inonetsa: Zvinwiwa zvinonamira, tsvina, kana masisitimu anocheneswa.
3. Kudzivirira ramangwana: Mapurojekiti anotarisira kuwedzera kwehuwandu hwemvura inoyerera.
Kufunga Nezvemutengo:
Mavharuvhu epombi yakazara anodhura 20-30% kupfuura kuderedza pombi asi anoderedza kushandiswa kwesimba kusvika ku15% mumasisitimu ane mvura yakawanda.
Nguva yekutumira: Kukadzi-15-2025
