Ho Utloisisa Bophara ba Lebitso

Tlhaloso eaBophara ba lebitso

Bophara ba lebitso, boo hangata bo khutsufatswang e le DN (ho tswa ho "Durchmesser" ya Sejeremane e bolelang bophara) ditsamaisong tsa metric kapa NPS (Boholo ba Pipe e sa Lekanyetswang) ditsamaisong tsa borena, ke boholo bo tlwaelehileng ba diphaephe le dikarolo tse amanang le tsona. Hase tekanyo e nepahetseng ya bophara ba mmele ba phaephe kapa sehokelo. Ho ena le hoo, e sebetsa e le ntlha e tlwaelehileng ya referense ho netefatsa hore dikarolo tse fapaneng di a tsamaellana ka hara sistimi ya diphaephe.

Mohlala, phaepheng ea DN 50 tsamaisong ea metric, bophara ba 'nete ba kantle ba phaephe bo kanna ba se be 50 mm hantle. Bophara ba 'nete ba kantle bakeng sa phaephe ea tšepe ea DN 50, ho latela litlhaloso tse tloaelehileng, hangata bo ka ba 60.3 mm. Bophara ba lebitso bo sebelisoa ho nolofatsa ho khetholla le ho khetha likarolo. Likarolo tsohle tse nang le bophara bo tšoanang ba lebitso, joalo ka liphaephe, li-flange le li-valve, li etselitsoe ho lekana hantle.

Bohlokoa ho Maemo a Boleng

Ho leka-lekanya bophara ba nominee ho na le melemo e 'maloa. Ho lumella hore ho be bonolo ho fapanyetsana likarolo. Femeng e kholo ea indasteri e nang le liphaephe le lisebelisoa tse ngata, ho ba le sistimi e tloaelehileng ea bophara ba nominee ho netefatsa hore likarolo tse ling li ka fumanoa kapele le ho kenngoa. Mohlala, haeba valve e ka har'a phaephe ea DN 80 e hloka ho nkeloa sebaka, valve efe kapa efe e nang le bophara ba nominee ba DN 80, ho sa tsotelehe moetsi (hafeela ba latela maemo a amehang), e lokela ho khona ho lekana hantle liphaepheng tse seng li ntse li le teng.

Ho feta moo, e nolofatsa tshebetso ya moralo. Baenjiniere ba ka totobatsa dikarolo tse itshetlehileng hodima bophara bo itseng ntle le ho tshwenyeha ka dipharologanyo tse nyane tsa bophara ba sebele. Sena se potlakisa moralo wa ditsamaiso tsa diphaephe, kaha di ka tsepamisa maikutlo hodima moralo le tshebetso yohle ho ena le ho tsieleha ka dintlha tse nepahetseng tsa boholo ba karolo ka nngwe.

Phapang pakeng tsa Imperial le MetricBophara ba lebitso

Tsamaisong ea borena, NPS e thehiloe ho lisenthimithara. Mohlala, phaephe ea NPS ea lisenthimithara tse 2 e na le bophara bo fapaneng ba 'nete ba kantle ha e bapisoa le phaephe ea DN 50 tsamaisong ea metric, leha li lekana hanyane ho latela boholo bo akaretsang. Tsamaiso ea borena e na le sete ea eona ea boholo bo tloaelehileng bakeng sa liphaephe le li-fitting, 'me phetoho lipakeng tsa NPS ea borena le DN ea metric ha se kamehla e leng bonolo. Leha ho le joalo, ho entsoe boiteko ba ho theha litekanyo tse batlang li lekana ho nolofatsa khoebo ea machaba le tšebelisano-'moho liindastering tse sebelisang litsamaiso tsena ka bobeli.

Qetellong, bophara bo tloaelehileng ke mohopolo oa motheo lefatšeng la litsamaiso tsa liphaephe. ​​E fana ka mokhoa o tloaelehileng oa ho khetholla le ho bapisa likarolo, ho nolofalletsa moralo o sebetsang hantle, ho kenya le ho hlokomela litsamaiso tsa ho sebetsana le metsi ho pholletsa le liindasteri tse fapaneng, ho tloha libakeng tsa ho hloekisa oli le khase ho ea marang-rang a phepelo ea metsi.
