Iimpompo ethe nkqoInjini yatshintsha ishishini lokupompa ekuqaleni kweminyaka yoo-1920 ngokuvumela ukuba iimoto zombane zinamathele phezulu kwipompo, nto leyo eyabangela iimpembelelo ezinkulu. Oku kwenza lula inkqubo yokufakela kwaye kwanciphisa iindleko ngenxa yemfuneko yeendawo ezimbalwa. Ukusebenza kakuhle kweemoto zepompo kwanda nge-30%, kwaye uhlobo oluthile lwenjongo yeemoto zepompo ezithe nkqo zazenza zahlala ixesha elide kwaye zithembeke ngakumbi xa kuthelekiswa nezinye zazo ezithe tye.
Iimoto zepompo ezithe nkqo zihlala zihlelwa ngokweentlobo zazo zeshaft, nokuba zingenanto okanye ziqinile.
Impompo ye-vertical hollow shaft (VHS)Iimoto kunye neemoto zepompo ze-vertical solid shaft (VSS) zinomahluko amaninzi kuyilo lwazo kunye nokusetyenziswa kwazo. Nazi ezinye zeendlela ezingundoqo zomahluko:
1. Uyilo lweShaft:
-Iimoto zepompo zeVHSine-shaft engenanto, evumela i-shaft yepompo ukuba idlule kwi-motor ukuze iqhagamshele ngqo kwi-impeller. Olu yilo lususa isidingo sokudibanisa okwahlukileyo kwaye lunciphisa ubude bendibano ye-pump-motor.
-Iimoto zempompo zeVSSine-shaft eqinileyo esuka kwi-motor ukuya kwi-impeller. Ulwandiso lwe-shaft ludla ngokuba ne-keyway ejikelezayo yokudlulisa i-pump thrust kunye ne-radial keyway yokudlulisa i-torque. Ukudibana kwesiphelo esisezantsi phakathi kwe-pump motor kunye ne-pump shaft kudla ngokubonwa kwiitanki nakwii-shallow pumps, ngokungafaniyo nemisebenzi ye-deep-well.
2. Isicelo:
- Iimoto zempompo zeVHS zisetyenziswa rhoqo kwimithombo enzulu kunye nokusetyenziswa kwempompo engaphantsi komhlaba apho umngxuma wempompo udlulela emfuleni okanye kwisump.
- Iimoto zempompo zeVSS zihlala zisetyenziswa kwiindawo apho umngxuma wempompo ungadingi kudlulela equleni okanye esump, njengeempompo ezikwimigca okanye kwiindawo apho impompo ingaphezulu kwamanzi.
3. Ulondolozo:
- Iimoto zempompo zeVHS zinokuba lula ukuzigcina nokuzilungiselela ngenxa yonxibelelwano oluthe ngqo phakathi kwemoto kunye nomngxuma wempompo. Nangona kunjalo, ukufikelela kwimoto ukuze ilungiswe kunokuba nzima ngakumbi ngenxa yendawo ekuyo equleni okanye esump.
- Iimoto zempompo zeVSS zinokufuna ukugcinwa rhoqo kwekhonkco phakathi kwemoto kunye nomngxuma wempompo, kodwa imoto ngokwayo inokufikeleleka lula ukuze ilungiswe.
Malunga neeMoto zeHollow Shaft ezime nkqo: Zenzelwe ntoni iiMoto zeHollow?
Iimoto ze-vertical hollow shaft (VHS) zenzelwe ukusetyenziswa okuthile apho i-pump shaft ifikelela equleni okanye e-sump.
Ekuqaleni, iimpompo ezingaphezulu komhlaba zazisetyenziselwa ukunkcenkceshela kwiindawo ezomileyo kodwa ezilungele ezolimo, njengeCalifornia. Ezi mpompo zazinezixhobo zegiya esekunene kwaye zazisebenza ngeenjini zokutsha zangaphakathi. Ukungeniswa kweemoto zombane phezu kweempompo kwasusa imfuneko yebhokisi yegiya yoomatshini yokubonelela ngee-torque kunye neebheringi zangaphandle zokutyhala ipompo eyongezelelweyo. Oku kuncipha kwezixhobo kwabangela iindleko eziphantsi, ubungakanani obuncinci, ukufakwa lula, kunye neenxalenye ezimbalwa. Iimoto zepompo ezithe nkqo zikwasebenza malunga nama-30% ngokufanelekileyo kuneemoto ezithe tye kwaye zenzelwe ngokukodwa umsebenzi, zibonelela ngokuqina okuphezulu kunye nokuthembeka kwezicelo zepompo. Ngaphezu koko, zenzelwe ukumelana neemeko ezahlukeneyo zendalo. Ngenxa yoko, ukulima eCalifornia kwakwazi ukuchuma phantsi kwezi meko.
Ngaba Ndingakhetha iSolid Shaft Motor okanye iHollow Shaft Motor ukuze Ndenze Lo Msebenzi?
Ukukhetha imoto yomatshini oqinileyo okanye imoto yomatshini ongenanto efanelekileyo kumsebenzi othile kuxhomekeke kwiimfuno zokusetyenziswa kunye neemeko zokusingqongileyo. Iimoto zomatshini oqinileyo zihlala zisetyenziswa kwiindawo apho i-pump shaft ingadingi kudlulela equleni okanye kwi-sump, njengeempompo ezikwi-line okanye ukufakelwa okungaphezulu komhlaba. Kwelinye icala, iimoto zomatshini ongenanto zifanelekile kwiindawo ezinzulu kunye neendawo ezingaphantsi komhlaba, apho i-pump shaft idlulela equleni okanye kwi-sump.
Ukongeza kwiinkcukacha ezisemgangathweni ezifana namandla ehashe, isantya, indawo ebiyelweyo, amandla okufaka, kunye nobukhulu besakhelo obunxulunyaniswa nazo zonke iimoto zokungenisa, iimoto ze-vertical hollow shaft (VHS) nazo zinemfuno ezithile zokutyhala. Umthamo wokutyhala wemoto kufuneka udlule amandla e-axial apheleleyo eya kudibana nawo, kubandakanya ubunzima be-rotor, i-pump line shaft kunye ne-impeller, kunye namandla aguqukayo afunekayo ukuphakamisa ulwelo kumphezulu.
Kukho iindlela ezintathu okanye i-thrust: ii-normal thrust motors, ii-medium thrust motors, kunye nee-high thrust motors. I-horizontal motor ithathwa njenge-thrust motor eqhelekileyo kwaye ifanelekile ukusetyenziswa ngokubanzi apho kusetyenziswa i-thrust yangaphandle encinci kwi-motor bearing.
Imoto eqhubayo ephakathi, eyaziwa ngokuba yimoto eqhubayo emgceni, yenzelwe imisebenzi ethile kwaye ithathwa njengemoto enenjongo ethile. Ii-impellers zifakelwa ngqo kwi-motor shaft, kwaye i-thrust bearing ihlala ibekwe ezantsi ukuthintela ukukhula kobushushu be-rotor ekuchaphazeleni iindawo ezivulekileyo ze-impeller. Kufuneka ukunyamezelana kokuphuma kwe-motor shaft kunye ne-flange, njengoko ukusebenza kwe-impeller kuxhomekeke ekunyamezeleni okusondeleyo kwe-pump housing.
Injini eqhuba ngamandla inokwenziwa ngokwezifiso ngumvelisi kwaye idla ngokunika amandla okuqhuba angama-100%, 175%, okanye 300%, apho i-thrust bearing idla ngokuba kufutshane nephezulu.
Ukuba ufuna uncedo ekukhetheni injini efanelekileyo yomsebenzi wakho, ungathandabuzi ukuqhagamshelana neengcali eTkflo. Siyavuya ukuphendula nayiphi na imibuzo onokuba nayo malunga nokukhetha injini ethe nkqo engenanto ngokweemfuno zakho ezithile.
Zithini Izicelo ZaloIimpompo zeTurbine ezithe nkqo?
Izicelo zeeMpompo zeTurbine eziMileyo ziquka ukusetyenziswa okuhlukeneyo kubonelelo lwamanzi, ukunkcenkceshela, iinkqubo zoshishino, kunye neenkqubo zamanzi zikamasipala. Zisetyenziselwa ukunkcenkceshela kwezolimo, ukudluliselwa kwamanzi kwiinkqubo zobonelelo lwamanzi zikamasipala, kunye neenkqubo zoshishino ezifana nokujikeleza kwamanzi okupholisa kunye nonyango lwamanzi amdaka.
Impompo ye-turbine ethe nkqo (VTP) luhlobo lwempompo yamandla ejikelezayo ene-radial okanye i-radial flow impeller ephuculweyo. Ezi mpompo zihlala zinezigaba ezininzi, zifaka amanqanaba amaninzi e-impeller ngaphakathi kwendibano yesitya, kwaye zinokuhlulwahlulwa njengeempompo zemithombo enzulu okanye iimpompo ezimfutshane.
I-turbine yomthombo onzulu idla ngokufakelwa kwiqula eligrunjiweyo, apho i-impeller yesigaba sokuqala ibekwe ngaphantsi komgangatho wamanzi wepompo. Ezi pumps ziyazilungiselela ngokwazo, zihlala zidibanisa izigaba ezininzi, kwaye zisetyenziselwa kakhulu ukuhambisa amanzi. Ukusetyenziswa kwazo okuphambili kubandakanya ukuthutha amanzi ukusuka kwiqula elinzulu ukuya kumphezulu.
Ezi pump zithutha amanzi kwiindawo zokunyanga, kwiinkqubo zokunkcenkceshela, nakwiimpompo zasekhaya. Iipump ezimfutshane zisebenza ngendlela efanayo neepump ezinzulu, zisebenza kwimithombo yamanzi angaphantsi kakhulu enobunzulu obuphezulu obumalunga ne-40 ft.
Ipompo ye-VTP ingafakwa kwibhareli yokufunxa okanye ngaphantsi komhlaba ukuze kwandiswe iintloko zokufunxa kwi-impeller yesigaba sokuqala. Ezi pump zihlala zisetyenziswa njengeempompo zokunyusa okanye kwezinye iindawo apho i-low net positive suction head (NPSH) ifikeleleka khona.
Ukukwazi kwabo ukusingatha amazinga aphezulu okuhamba kwamanzi nokusebenza ngokufanelekileyo kwiindawo ezinzima kubenza bafaneleke kwiintlobo ngeentlobo zezicelo, kuquka nezo zifuna ukuhanjiswa kwamanzi ngoxinzelelo oluphezulu.
