Impompo entsha yeHydrant yoMlilo iphucula uShishino kunye noKhuseleko oluPhezulu
Kwinkqubela phambili ebalulekileyo yokhuseleko lwezoshishino kunye nokunyuka okuphezulu, iteknoloji yepompo yepompo yomlilo yamva nje ithembisa ukuhambisa ukusebenza okukhethekileyo kunye nokuthembeka kwiinkqubo zokucima umlilo. Kubandakanya i-impellers ezininzi ze-centrifugal, ii-volutes, iipayipi zokuhambisa, i-shafts zokuqhuba, iziseko zempompo, kunye neenjini, ezi mpompo zenzelwe ukujongana noluhlu olubanzi lweemfuno zokucima umlilo.
uSetyenziso lwaMalunga angundoqo
Iimpompo yombhobho womliloInkqubo iyilwe ngamandla kunye namacandelo abalulekileyo abandakanya isiseko sempompo kunye nemoto, ezibekwe ngaphezulu kwendawo yokugcina amanzi. Amandla athunyelwa ukusuka kwi-motor ukuya kwi-impeller shaft nge-concentric drive shaft exhunywe kumbhobho wokuhambisa. Olu cwangciso luqinisekisa ukuveliswa kokuhamba okubalulekileyo kunye noxinzelelo, okuyimfuneko ekucimeni umlilo okusebenzayo.
1.ICandelo lokuSebenza
Icandelo elisebenzayo lempompo liqukethe iindawo ezininzi eziphambili: i-volute, i-impeller, i-cone sleeve, ii-casing bearings, kunye ne-impeller shaft. I-impeller ibonisa uyilo oluvaliweyo, olubalulekileyo ekugcineni ukusebenza kakuhle kunye nokuqina. Amacandelo e-casing adityaniswe ngokukhuselekileyo kunye, kwaye zombini i-volute kunye ne-impeller inokuxhotyiswa ngamakhonkco angaguqukiyo ukwandisa ubomi babo bokusebenza.
2.ICandelo leMibhobho yokuhanjiswa
Eli candelo libandakanya umbhobho wokuhambisa, i-shaft drive, i-couplings, kunye namacandelo axhasayo. Umbhobho wokuhambisa udibaniswe ngeeflange okanye iintambo ezidibeneyo. I-shaft ye-drive yenziwe ngentsimbi ye-2Cr13 okanye insimbi engenasici. Kwiimeko apho i-drive shaft bearings experience wear, i-threaded connections ivumela ukutshintshwa kwemibhobho yokuhambisa emfutshane, ukwenza ukugcinwa ngokuthe ngqo. Kuqhagamshelo lweflange, ukutshintsha ngokulula isalathiso se-drive shaft kunokubuyisela ukusebenza. Ukongezelela, ikhonkco elikhethekileyo lokuvala uxhulumaniso phakathi kwesiseko sempompo kunye nombhobho wokuhambisa ukhusela ukuchithwa ngengozi.
3.Wellhead iCandelo
Icandelo le-wellhead linesiseko sempompo, i-motor yombane enikezelweyo, i-motor shaft, kunye ne-couplings. Izixhobo ezikhethiweyo ziquka ibhokisi yokulawula umbane, umbhobho omfutshane ophumayo, i-valve yokungena kunye ne-exhaust valves, ii-gauges zoxinzelelo, ii-valve zokujonga, ii-valve zesango, kunye neengqungquthela eziguquguqukayo ezenziwe kwi-rubber okanye insimbi engenasici. La macandelo aphucula ukuguquguquka kwempompo kunye nokulula kokusetyenziswa kwiimeko ezahlukeneyo zokucima umlilo.
Izicelo kunye neeNzuzo
Iimpompo ze-Fire hydrant ziqeshwe ngokukodwa kwiinkqubo ezisisigxina zokucima umlilo kumashishini amashishini, iiprojekthi zokwakha, kunye nezakhiwo eziphakamileyo. Ziyakwazi ukuhambisa amanzi acacileyo kunye nolwelo kunye neempawu zeekhemikhali ezifanayo, okwenza ukuba zilungele uluhlu olubanzi lwezicelo. Ezi mpompo zikwasetyenziswa ekuhlaleniiinkqubo zokubonelela ngamanzi, unikezelo lwamanzi nokuhanjiswa kwamanzi kamasipala, kunye nezinye iinkonzo ezibalulekileyo.
Iimpompo ze-Fire Hydrant: Imiqathango yokusetyenziswa ebalulekileyo
Ukuqinisekisa ukusebenza ngokugqibeleleyo kunye nobomi obude beempompo zomlilo ezinzulu kubandakanya ukuthobela imiqathango ethile yokusetyenziswa, ngakumbi malunga nobonelelo lwamandla kunye nomgangatho wamanzi. Nazi iimfuno ezineenkcukacha:
1.Ireyithingi yeFrequency kunye neVoltage:Iinkqubo yomliloifuna i-frequency elinganisiweyo ye-50 Hz, kwaye i-voltage elinganisiweyo yemoto kufuneka igcinwe kwi-380±5% ye-volts kwisigaba sesithathu sombane we-AC.
2.Umthwalo weTransformer:Amandla omthwalo we-transformer akufanele adlule i-75% yomthamo wayo.
3.Umgama ukusuka kwiTransformer ukuya eWellhead:Xa i-transformer ikude ne-wellhead, i-voltage drop in the line transmission kufuneka ithathelwe ingqalelo. Kwiimoto ezinomlinganiselo wamandla angaphezu kwe-45 KW, umgama phakathi kwe-transformer kunye ne-wellhead akufanele idlule i-20 yeemitha. Ukuba umgama ungaphezu kweemitha ezingama-20, iinkcukacha zomgca wothumelo kufuneka zibe ngamanqanaba amabini aphezulu kuneenkcazo zekhebula zokusasaza ukujongana nokuhla kwamandla ombane.
Iimfuno zoMgangatho waManzi
1.Amanzi angaNdleliyo:Amanzi asetyenzisiweyo kufuneka angonakali.
2.Umxholo oSolid:Umxholo oqinileyo emanzini (ngobunzima) akufanele udlule i-0.01%.
3.Ixabiso le-pH:Ixabiso le-pH yamanzi kufuneka libe phakathi koluhlu lwe-6.5 ukuya kwi-8.5.
4.Umxholo weHydrogen sulfide:Umxholo we-hydrogen sulfide akufanele udlule i-1.5 mg / L.
5.Ubushushu baManzi:Ubushushu bamanzi akufunekanga bube ngaphezulu kwama-40°C.
Ukubambelela kule miqathango kubalulekile ekugcineni ukusebenza kakuhle kunye nokuqina kweempompo zombhobho womlilo. Ngokuqinisekisa ukunikezelwa kwamandla okufanelekileyo kunye nomgangatho wamanzi, abasebenzisi banokwandisa ukusebenza kunye nokwandisa ixesha lokuphila kweenkqubo zabo zempompo zomlilo, ngaloo ndlela baphucula ukuthembeka kunye nokukhuseleka kweziseko zabo zokukhusela umlilo.
Isebenza njani inkqubo yempompo yombhobho womlilo?
Impompo yombhobho wokucima umlilo yonyusa uxinzelelo kwisixokelelwano sombhobho-manzi xa uxinzelelo lukamasipala lungonelanga okanye ii-hydrants zondliwa ngetanki.Ngoko ke kwandisa isakhono sokucima umlilo kwisakhiwo. Ngokuqhelekileyo, amanzi akwinkqubo yokuhambisa amanzi acinezelekile kwaye alungele ukusetyenziswa ngokungxamisekileyo. Xa abacimi bomlilo bevula ipompo ye-hydrant, uxinzelelo lwamanzi luyehla, olubangela ukutshintshwa koxinzelelo ukuze kusebenze impompo ye-booster.
Ipompo yombhobho womlilo ibalulekile xa unikezelo lwamanzi lungonelanga ukuhlangabezana nokuhamba kunye neemfuno zoxinzelelo lwenkqubo yokucima umlilo. Nangona kunjalo, ukuba unikezelo lwamanzi sele ludibana noxinzelelo olufunekayo kunye nokuhamba, ipompo yokucima umlilo ayifuni.
Isishwankathelo, ipompo ye-fire hydrant iyimfuneko kuphela xa kukho ukunqongophala kwamanzi kunye noxinzelelo.
