Mokhoa oa ho BalaPompo ea Metsi a MolloKhatello?
Ho bala khatello ea pompo ea mollo, u ka sebelisa foromo e latelang:
Foromo:
Moo:
· P = Khatello ea pompo ho psi (liponto ka lisenthimithara tse lisekoere)
· Q = Sekhahla sa phallo ka lilithara ka motsotso (GPM)
· H = Kakaretso ea hlooho e matla (TDH) maotong
· F = Tahlehelo ea likhohlano ka psi
Mehato ea ho Lekanya Khatello ea Pompo ea Mollo:
Fumana Sekhahla sa Phallo (Q):
· Hlalosa sekhahla sa phallo e hlokahalang bakeng sa sistimi ea hau ea ts'ireletso ea mollo, eo hangata e boletsoeng ho GPM.
Bala Total Dynamic Head (TDH):
· Hlooho e tsitsitseng: Lekanya sebaka se otlolohileng ho tloha mohloling oa metsi ho ea sebakeng se phahameng ka ho fetisisa sa ho tsoa.
· Tahlehelo ea Khohlano: Bala tahlehelo ea khohlano tsamaisong ea lipeipi u sebelisa lichate kapa liforomo tsa tahlehelo ea khohlano (joalo ka equation ea Hazen-Williams).
· Tahlehelo ea Phahamiso: Akhaonto bakeng sa liphetoho leha e le life tsa bophahamo tsamaisong.
[TDH= Hlooho e tsitsitseng + Tahlehelo ea Khohlano + Tahlehelo ea Phahamiso]
Bala tahlehelo ea Khohlano (F):
· Sebelisa mekhoa e nepahetseng kapa lichate ho fumana tahlehelo ea khohlano ho latela boholo ba liphaephe, bolelele le sekhahla sa phallo.
Hokela Litekanyetso ho Foromo:
• Kenya boleng ba Q, H, le F sebakeng sa foromo ho bala khatello ea pompo.
Palo ea Mohlala:
· Sekhahla sa Phallo (Q): 500 GPM
· Kakaretso ea Hlooho e Matla (H): maoto a 100
· Tahlehelo ea Khohlano (F): 10 psi
Ho sebelisa foromo:
Lintlha tsa bohlokoa:
· Netefatsa hore khatello e baloang e kopana le litlhoko tsa sistimi ea ts'ireletso ea mollo.
· Kamehla sheba maemo a NFPA le likhoutu tsa lehae bakeng sa litlhoko le litataiso tse itseng.
· Buisana le moenjiniere oa tšireletso ea mollo bakeng sa litsamaiso tse rarahaneng kapa ha o na bonnete ba lipalo.
U Sheba Joang Khatello ea Pompo ea Mollo?
Ho hlahloba khatello ea pompo ea mollo, u ka latela mehato ena:
1. Bokella Lisebelisoa tse Hlokehang:
Pressure Gauge: Netefatsa gore o na le selekanyo se se lekanyeditsweng sa kgatelelo se se ka kgonang go lekanya selekanyo sa kgatelelo e e solofetsweng.
Wrenches: Bakeng sa ho hokahanya gauge ho pompo kapa liphaephe.
Lisebelisoa tsa Tšireletso: Apara lisebelisoa tse nepahetseng tsa tšireletso, ho kenyeletsoa liatlana le likhalase.
2. Fumana Boema-kepe ba Teko ea Khatello:
Hlalosa boema-kepe ba teko ea khatello tsamaisong ea pompo ea mollo. Hangata sena se fumaneha ka lehlakoreng la ho tsoa ha pompo.
3. Hokela Sekala sa Khatello:
Sebelisa lisebelisoa tse loketseng ho hokela tekanyo ea khatello ho koung ea liteko. Netefatsa tiiso e tiileng ho thibela ho lutla.
4. Qala Pompo ea Mollo:
Bulela pompo ea mollo ho latela litaelo tsa moetsi. Netefatsa hore sistimi e hloekisitsoe 'me e loketse ho sebetsa.
5. Ela Hloko ho Bala Khatello:
Hang ha pompo e ntse e sebetsa, ela hloko khatello e baloang ho gauge. Sena se tla u fa khatello ea ho tsoa ha pompo.
6. Rekota Khatello:
Ela hloko khatello ea ho bala litlaleho tsa hau. E bapise le khatello e hlokahalang e boletsoeng moralong oa sistimi kapa litekanyetso tsa NFPA.
7. Sheba Liphapang:
Haeba ho hlokahala, hlahloba khatello ka litekanyetso tse fapaneng tsa phallo (haeba tsamaiso e lumella) ho netefatsa hore pompo e sebetsa ka katleho ho pholletsa le mefuta ea eona.
8. Koala Pompo:
Kamora ho etsa liteko, koala pompo ka mokhoa o sireletsehileng 'me u hakolle tekanyo ea khatello.
9. Hlahloba Mathata:
Ka mor'a ho etsa tlhahlobo, hlahloba tsamaiso bakeng sa ho lutla hofe kapa hofe kapa ho sa tloaelehang ho ka hlokang ho hlokomeloa.
Lintlha tsa bohlokoa:
Tšireletseho Pele: Kamehla latela liprothokholo tsa tšireletso ha u sebetsa ka lipompo tsa mollo le lisebelisoa tse hatelitsoeng.
Teko e Tloaelehileng: Ho hlahlojoa khafetsa khatello ke habohlokoa bakeng sa ho boloka botšepehi ba pompo ea mollo.
Khatello e Nyenyane ea Masala Bakeng sa Pompo ea Mollo ke Efe?
Khatello e fokolang e setseng bakeng sa lipompo tsa mollo hangata e itšetlehile ka litlhoko tse khethehileng tsa tsamaiso ea ts'ireletso ea mollo le likhoutu tsa sebaka seo. Leha ho le joalo, maemo a tloaelehileng ke hore khatello e fokolang ea masala e lokela ho ba bonyane 20 psi (liponto ka lisenthimithara tse sekoere) sebakeng se hole haholo sa hose nakong ea maemo a phallo e phahameng.
Sena se tiisa hore ho na le khatello e lekaneng ea ho fana ka metsi ka katleho tsamaisong ea ho thibela mollo, joalo ka li-sprinklers kapa li-hoses.
Horizontal split casing centrifugal pumps e lumellana le NFPA 20 le litlhoko tsa kopo tse thathamisitsoeng ho UL le lisebelisoa tse nepahetseng bakeng sa ho fana ka phepelo ea metsi litsamaisong tsa ts'ireletso ea mollo meahong, limela tsa lifeme le lijarete.
