Isando samanzi senzeka lapho kunqamuka ugesi kungazelelwe noma lapho i-valve ivaleka ngokushesha okukhulu. Ngenxa ye-inertia yokugeleza kwamanzi okucindezela, igagasi lokushaqeka lokugeleza kwamanzi liyakhiqizwa, njengesando esishayayo, ngakho-ke kubizwa ngokuthi isando samanzi.

Isando samanzi esiteshini sokumpompa sihlanganisa isando samanzi sokuqala, isando samanzi sokuvala ivalvu kanye nesando sokumisa amanzi sephampu (okubangelwa ukunqamuka kukagesi kungazelelwe nezinye izizathu). Izinhlobo ezimbili zokuqala zesando samanzi ngeke zibangele izinkinga ezibeka engozini ukuphepha kweyunithi ngaphansi kwezinqubo ezijwayelekile zokusebenza. Inani lomfutho wesando samanzi elakhiwe yilokhu lakamuva livame ukuba likhulu kakhulu, libangele izingozi.

Isando Samanzi Lapho Split Case Centrifugal Pump Imisiwe

Okubizwa ngokuthi isando samanzi se-pump-stop sibhekisela esimweni sokushaqeka kwe-hydraulic okubangelwa izinguquko ezisheshayo zejubane lokugeleza empompini yamanzi kanye namapayipi okucindezela lapho i-valve ivuliwe futhi imiswa ngenxa yokunqamuka kwamandla okungazelelwe noma ezinye izizathu. Isibonelo, ukwehluleka kwesistimu yamandla noma okokusebenza kukagesi, ukwehluleka ngezikhathi ezithile kweyunithi yepompo yamanzi, njll. kungase kubangele iphampu ye-centrifugal ukuthi ivule ivalvu futhi ime, kubangele isando samanzi lapho icala lokuhlukanisa iphampu ye-centrifugal iyama.

Ukucindezela okukhulu kwesando samanzi lapho iphampu kumiswa kungafinyelela ku-200% wengcindezi evamile yokusebenza, noma ngisho nangaphezulu, engacekela phansi amapayipi nemishini. Izingozi ezijwayelekile zidala "ukuvuza kwamanzi" kanye nokunqamuka kwamanzi; izingozi ezimbi kakhulu zidala ukuthi igumbi lokumpompa ligcwale amanzi, kulimale izinto zokusebenza, nokulimala kwezinsiza. ukulimaza noma ukubangela ukulimala komuntu siqu noma ukufa.

Izingozi Zomphumela Wesando Samanzi

Ukwenyuka kwengcindezi okubangelwa isando samanzi kungafinyelela izikhathi eziningana noma ngisho namashumi ezikhathi zokucindezela okuvamile kwepayipi. Izingozi eziyinhloko ezidalwa yilokhu kuguquguquka okukhulu kwengcindezi ohlelweni lwamapayipi zihlanganisa:

1. Banga ukudlidliza okuqinile epayipini kanye nokunqanyulwa kwamalunga amapayipi

2. Ukucekela phansi ama-valve, kubangele ukuqhuma kwepayipi ngenxa yokucindezela okukhulu ngokweqile, futhi kunciphise ingcindezi yenethiwekhi yokuphakelwa kwamanzi.

3. Ngokuphambene nalokho, ukucindezela okuphansi kakhulu kuzobangela ukuba ipayipi iwe futhi ilimaze i-valve nezingxenye zokulungisa

4. Ukubangela ukuthi iphampu ye-centrifugal ihlehliseke emuva, yonakalise okokusebenza noma amapayipi egumbini lokumpompa, kubangele ukuthi igumbi lepompo ligcwale amanzi, kubangele ukulimala komuntu siqu nezinye izingozi ezinkulu, ezithinta ukukhiqizwa nokuphila.
