Ngā Takirere Pōro Taunga Katoa: Ngā Mātāpono Hoahoa, Ngā Tātaitanga, me Ngā Whakamahinga Ahumahi
He mea nui te whānui o te awa rere o te takirere pōro hei āhuatanga mahi.ngā takirere pōro tauranga katoa, ko tēnei āhuatanga e whakatau ana i te pai o te rere, te ngaronga o te pēhanga, me te pai mō ngā ahumahi e hiahiatia ana. Anei me pēhea te hanga me te whakatinana i aua mea.
Takirere Pōro Tauranga Katoa: Whakamāramatanga me ngā Tikanga Tātai
1. Whakamāramatanga Matua
He rite te whānui o te awa rere o te takirere pōro tauranga-katoa (puku-katoa) ki te ≥95% o te whānui o roto o te paipa, e āhei ai te rere tata kore here me te iti o te hekenga pēhanga.
2. Tātaitanga e hangai ana ki te rere
Whakamahia te tātai hihiri wai empirika:
Q = K × Cv × √ΔP
Q: Te tere rere (GPM, m³/h rānei)
K: Tauwehenga whakatikatika (te tikanga 0.9)
Cv: Tauwehenga rere (motuhake ki te takirere)
ΔP: Rerekētanga pēhanga (psi, pae rānei)
Te tātai whānui poka i ahu mai:
d = (Q / (0.9 × Cv × √ΔP)) × 25.4
(d = diameter i roto i te mm; 25.4 = huringa inihi-mm)
3. Te Pokatata Rahi o te Paipa
d = D × 0.8
d: Te whānui o te poka takirere
D: Te whānui o waho o te paipa
Tauira: Mō te paipa OD 100mm, tīpakohia he takirere he ≥80mm te poka.
Tauranga Katoa me te Tauranga WhakaitiNgā Rerekētanga Tino Hira
Tawhā | Takirere Pōro Tauranga Katoa | Whakaitihia te takirere pōro o te tauranga |
|---|---|---|
| Hongere Rere | E ōrite ana ki te ID paipa (hei tauira, DN50 = 50mm) | 1-2 ngā rahi iti ake (hei tauira, DN50 ≈ 38mm) |
| Te Whai Hua o te Rere | Ātete tata ki te kore; rere katoa | Te whakahekenga rere 15-30% |
| Te hekenga o te pēhanga | Kāore i te tino mōhiotia | He mea nui i ngā tere rere teitei |
| Ngā tono | He mea nui mō ngā wai whakapūpū, matotoru | Ngā pūnaha rere-iti; ngā kaupapa e aro nui ana ki te utu |
Ngā Tirohanga Matua:
Ka mau tonu te rere o te takirere DN50 ki te 50mm, ā, ka whakaitihia te rere e te takirere DN50 whakaiti-putanga ki te ~DN40 (38mm) – he 24% te ngaronga o te horahanga rere.
Ngā Taupānga Ahumahi: Te Wāhi e Hiranga ai ngā Takirere Putanga Katoa
1. Ngā Paipa Hinu me te Hau
Mahi:Te whakaweto/te whakahaere i te raina pūtu
Painga:Ka taea te whakapūmau i ngā paipa hei tiaki; ka taea te whakahaere i te hinu mata/paraoa me te kore e aukati.
2. Te Tukatuka Matū
Whakamahinga Take:Ngā raina whāngai tauhohenga rere-teitei
Painga:Ārai i ngā here rere e whakararuraru ana i te haere tonu o te whakaputanga.
3. Te Whakahaere Wai
Ngā tono:
1. Ngā puna wai o te tāone
2. Ngā putanga/ngā putanga o te whare horoi wai para
He aha: Ka whakanui ake i te rere o te wai mō ngā wā tino hiahiatia.
Aratohu Kōwhiri: Āhea te Kōwhiri i te Taunga Katoa
Kōwhiria ngā takirere putanga katoa ina:
1.He mea nui te rere:Ngā pūnaha e hiahia ana kia iti rawa te ngaronga pēhanga (hei tauira, ngā paipa tawhiti).
2. He wero te pāpāhoNgā wai mātotoru, ngā paru pokepoke, ngā pūnaha horoi rānei.
3. Te whakapūmau i te heke maiNgā kaupapa e matapae ana i te pikinga o te tere rere.
Whakaaroaro Utu:
He 20-30% te utu nui ake mō ngā takirere tauranga katoa i te tauranga iti iho, engari ka whakaitihia te whakapaunga pūngao tae atu ki te 15% i roto i ngā pūnaha rere-rahi.
