Iphampu Ye-Fire Hydrant Entsha Ithuthukisa Ukuphepha Kwezimboni Nokuphakama Okuphakeme

Ekuthuthukisweni okuphawulekayo kokuphepha kwezimboni kanye nokukhuphuka okuphezulu, ubuchwepheshe bamuva bephampu ye-fire hydrant buthembisa ukuletha ukusebenza okuyingqayizivele nokuthembeka ezinhlelweni zokucisha umlilo. Kuhlanganisa ama-impeller amaningi amaphakathi, ama-volute, amapayipi okulethwa, ama-drive shaft, ama-pump bases, nama-motor, lawa maphampu akhelwe ukubhekana nohlu olubanzi lwezidingo zokucisha umlilo.

Key Components Operation

Iiphampu ye-fire hydrantisistimu iklanywe ngokuqinile ngezingxenye ezibalulekile ezihlanganisa isisekelo sepompo kanye ne-motor, ezibekwe ngaphezu kwedamu lamanzi. Amandla adluliswa esuka kumotho aye ku-impeller shaft ngokusebenzisa i-concentric drive shaft exhunywe epayipini lokulethwa. Lokhu kusetha kuqinisekisa ukukhiqizwa kokugeleza okubalulekile nokucindezela, okubalulekile ekucimeni umlilo okusebenzayo.

1.Isigaba sokuSebenza

Ingxenye yokusebenza yepompo iqukethe izingxenye ezimbalwa ezibalulekile: i-volute, impeller, umkhono wekhoni, ama-casing bearings, kanye ne-impeller shaft. I-impeller inomklamo ovaliwe, obalulekile ekugcineni ukusebenza kahle okuphezulu nokuqina. Izingxenye ze-casing ziboshwe ndawonye ngokuvikelekile, futhi kokubili i-volute ne-impeller ingahlonyiswa ngamasongo angagugi ukuze inwebe impilo yazo yokusebenza.

2.Delivery Pipe Isigaba

Lesi sigaba sihlanganisa ipayipi lokulethwa, i-drive shaft, ama-coupling, nezingxenye ezisekelayo. Ipayipi lokulethwa lixhunywe ngama-flanges noma ama-threaded joints. I-drive shaft yenziwe ngensimbi engu-2Cr13 noma insimbi engagqwali. Ezimeni lapho amabheringi e-drive shaft ehlangabezana nokuguga, ukuxhuma okunentambo kuvumela ukushintshwa kwamapayipi okulethwa amafushane, okwenza ukulungiswa kuqonde. Ngokuxhunywa kwe-flange, ukumane ushintshe isiqondiso se-drive shaft kungabuyisela ukusebenza. Ukwengeza, indandatho yokukhiya ekhethekile ekuxhumekeni phakathi kwesisekelo sepompo kanye nepayipi lokulethwa kuvimbela ukuhlukaniswa ngengozi.

3.Isigaba Somthombo

Ingxenye ye-wellhead inesisekelo sepompo, i-motor kagesi ezinikele, i-motor shaft, nama-couplings. Izesekeli ezikhethwayo zifaka ibhokisi lokulawula ugesi, ipayipi lokuphuma elifushane, amavalvu okungenisa nawokukhipha, amageji okucindezela, amavalvu okuhlola, amavalvu esango, namajoyinti aguqukayo enziwe ngerabha noma insimbi engagqwali. Lezi zingxenye zithuthukisa ukuguquguquka kwephampu kanye nokusebenziseka kalula kuzimo ezihlukahlukene zokucisha umlilo.

Izicelo Nezinzuzo

Amaphampu we-fire hydrant asetshenziswa ngokuyinhloko ezinhlelweni eziqinile zokucisha umlilo zamabhizinisi ezimboni, amaphrojekthi wokwakha, nezakhiwo eziphakeme. Bayakwazi ukuletha amanzi acacile kanye noketshezi olunezici ezifanayo zamakhemikhali, okubenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza. Lawa maphampu nawo asetshenziswa emphakathiniizinhlelo zokuhlinzeka ngamanzi, ukuhlinzekwa kwamanzi kamasipala kanye ne-drainage, nezinye izinsiza ezibalulekile.

Amaphampu e-Fire Hydrant: Imibandela Yokusebenzisa Ebalulekile

Ukuqinisekisa ukusebenza okuphelele nokuhlala isikhathi eside kwamaphampu omlilo ajulile kuhilela ukunamathela ezimweni ezithile zokusetshenziswa, ikakhulukazi mayelana nokuphakelwa kwamandla kanye nekhwalithi yamanzi. Nazi izimfuneko ezinemininingwane:

1.I-Frequency elinganiselwe kanye ne-Voltage:Iuhlelo lomliloidinga imvamisa elinganiselwe engu-50 Hz, futhi ugesi olinganiselwe wemoto kufanele ugcinwe eku-380±5% volts ekunikezeni amandla e-AC wezigaba ezintathu.

2.Umthwalo we-Transformer:Amandla omthwalo we-transformer akufanele adlule u-75% womthamo wawo.

3.Ibanga ukusuka e-Transformer kuya e-Wellhead:Lapho i-transformer itholakala kude nomthombo, ukwehla kwe-voltage emgqeni wokudlulisa kufanele kucatshangelwe. Kumamotho anesilinganiso samandla angaphezu kuka-45 KW, ibanga phakathi kwe-transformer ne-wellhead akufanele lidlule amamitha angu-20. Uma ibanga likhulu kunamamitha angu-20, imininingwane yolayini wokudlulisa kufanele ibe ngamaleveli amabili aphezulu kunezicaciso zekhebula lokusabalalisa ukuze kulandelwe ukwehla kwamandla kagesi.

Izidingo Zekhwalithi Yamanzi

1.Amanzi Angagqwali:Amanzi asetshenziswayo kufanele angoni.

2.Okuqukethwe Okuqinile:Okuqukethwe okuqinile emanzini (ngesisindo) akufanele kudlule i-0.01%.

3.Inani le-pH:I-pH yamanzi kufanele ibe phakathi kwebanga lika-6.5 kuya ku-8.5.

4.Okuqukethwe kweHydrogen Sulfidi:Okuqukethwe kwe-hydrogen sulfide akufanele kudlule u-1.5 mg/L.

5.Izinga Lokushisa Lamanzi:Izinga lokushisa lamanzi akufanele libe ngaphezu kuka-40°C.

Ukunamathela kule mibandela kubalulekile ukuze kugcinwe ukusebenza kahle nokuqina kwamaphampu okukhipha umlilo. Ngokuqinisekisa ukunikezwa kwamandla okufanelekile kanye nekhwalithi yamanzi, abasebenzisi bangathuthukisa ukusebenza futhi banwebe isikhathi sokuphila sezinhlelo zabo zephampu yomlilo, ngaleyo ndlela bathuthukise ukwethembeka nokuphepha kwengqalasizinda yabo yokuvikela umlilo.

Lusebenza kanjani uhlelo lwephampu yomthombo womlilo?

Iphampu yepayipi lomlilo inyusa ingcindezi ohlelweni lwamapayipi amanzi uma ingcindezi kamasipala inganele noma amapayipi amanzi efakwa ethangini. Ngaleyo ndlela ithuthukisa ikhono lesakhiwo lokucisha umlilo. Ngokuvamile, amanzi ohlelweni lwe-hydrant acindezelwa futhi alungele ukusetshenziswa okuphuthumayo. Lapho izicishamlilo zivula iphampu ye-hydrant, ukucindezela kwamanzi kuyehla, okubangela ukushintshwa kokucindezela ukuze kusebenze iphampu ye-booster.
Iphampu ye-fire hydrant ibalulekile lapho ukuhlinzekwa kwamanzi kunganele ukuhlangabezana nezidingo zokugeleza nengcindezi yesistimu yokucima umlilo. Kodwa-ke, uma ukunikezwa kwamanzi sekuvele kuhlangabezana nokucindezela okudingekayo nokugeleza, ipompo ye-fire hydrant ayidingeki.
Kafushane, iphampu ye-fire hydrant iyadingeka kuphela uma kunokuntuleka kokugeleza kwamanzi nokucindezela.
