Ukulinganisa amandla e-axial kwiimpompo ezininzi ze-centrifugal yiteknoloji ebalulekileyo yokuqinisekisa ukusebenza okuzinzileyo. Ngenxa yochungechunge lwe-impellers, i-axial forces iqokelela kakhulu (ukuya kwiitoni ezininzi). Ukuba ayilungelelaniswanga kakuhle, oku kunokukhokelela ekuthwaleni umthwalo omninzi, umonakalo wetywina, okanye ukusilela kwesixhobo. Apha ngezantsi kukho iindlela eziqhelekileyo zokulinganisa amandla e-axial, kunye nemigaqo yazo, izinto eziluncedo, kunye nezingeloncedo.
1.ULungiselelo lwe-Symmetrical Impeller (Umva-umva / uBuso ngobuso)
Kuyilo lwesixhobo se-axial yokulinganisa amandla wempompo ye-centrifugal yanamhlanje, inqanaba le-impeller likhethwa ngokubanzi njengenani elilinganayo, kuba xa inqanaba le-impeller linani elilinganayo, indlela yokusabalalisa i-impeller symmetrical ingasetyenziselwa ukulungelelanisa amandla e-axial yesixhobo, kunye namandla axial aveliswa yi-symmetrically i-impeller esasazwa ngokulinganayo kwi-impeller echaseneyo kunye ne-impeller echaseneyo kwindlela yokusebenza kunye ne-magtu isimo sokulingana kwinqanaba le-macroscopic. Kwinkqubo yoyilo, kufuneka kuqatshelwe ukuba ubukhulu be-throttling yokutywina phambi kokungena kwe-impeller ejikelezayo ihambelana nobubanzi be-impeller ukuqinisekisa ukutywinwa okulungileyo.
●Umgaqo: Ii-impellers ezimeleneyo zicwangciswe kumacala achaseneyo ukuze amandla azo axial arhoxise enye kwenye.
●Umva nomva: Iiseti ezimbini ze-impellers zifakwe ngokulinganayo malunga ne-midpoint shaft yepompo.
●Ubuso ngobuso: I-Impellers zicwangciswe zijonge ngaphakathi okanye ngaphandle kwi-mirrored configuration.
●Iingenelo: Akukho zixhobo zongezelelweyo ezifunekayo; isakhiwo esilula; ukusebenza kakuhle kokulinganisa (ngaphezulu kwama-90%).
●Iingxaki: Uyilo lwezindlu lwempompo olunzima; ukulungelelaniswa kwendlela yokuhamba; isebenza kuphela kwiimpompo ezinenani elilinganayo lezigaba.
●Usetyenziso: Iimpompo zebhoyila zoxinzelelo oluphezulu, iimpompo ze-petrochemical multistage.
2. Igubu lokulinganisa
I-balanced drum structure (eyaziwa ngokuba yi-balance piston) ayinayo i-axial running clearance, enokuthi ihlawule ininzi ye-axial thrust, kodwa kungekhona yonke i-axial thrust, kwaye akukho mbuyekezo eyongezelelweyo xa uhamba kwindawo ye-axial, kunye neebheringi zokubethelwa zifunwa ngokubanzi. Olu yilo luya kuba nokujikeleza okuphezulu kwangaphakathi (ukuvuza kwangaphakathi) kodwa kunokunyamezela ukuqalisa, ukuvalwa, kunye nezinye iimeko ezidlulayo.
●Umgaqo: I-drum ye-cylindrical ifakwe emva kwe-impeller yenqanaba lokugqibela. Ulwelo olunoxinzelelo oluphezulu luvuza ngomsantsa phakathi kwegubu kunye necasing kwigumbi elinoxinzelelo oluphantsi, ukuvelisa amandla okuchasa.
● Aizinto eziluncedo: Ukukwazi ukulinganisa okunamandla, okufanelekileyo kwi-high-pressure, iimpompo ze-multistage (umzekelo, i-10+ izigaba).
●Iingxaki: Ukulahleka kokuvuza (~ 3-5% yezinga lokuhamba), ukunciphisa ukusebenza kakuhle. Ifuna imibhobho yokulinganisa eyongezelelweyo okanye iinkqubo zokujikeleza kwakhona, ukwandisa ubunzima bokulondoloza.
●Usetyenziso: Iimpompo ezinkulu ze-multistage centrifugal (umzekelo, iimpompo zemibhobho yomgama omde).
3.Idisk yokulinganisa
Njengendlela yoyilo eqhelekileyo kwinkqubo yoyilo lwesixhobo se-axial force balance yempompo ye-multistage ye-centrifugal yanamhlanje, indlela ye-disc ye-balance inokulungelelaniswa ngokulinganayo ngokwemfuno yemveliso, kwaye amandla okulinganisela aveliswa yi-cross-section phakathi kwe-radial clearance kunye ne-axial clearance ye-disk, kunye nenye inxalenye yenziwe ngokuyinhloko yi-axial balance disc discs kunye necandelo le-disc ye-balance kunye necandelo le-balance ye-disk kunye necandelo le-balance ye-disk kunye nendima yokudlala indima. ukulinganisa amandla e-axial. Xa kuthelekiswa nezinye iindlela, i-advanteji yendlela yeplate yokulinganisela kukuba ububanzi bepleyiti yebhalansi inkulu kwaye uvakalelo luphezulu, oluphucula ngokufanelekileyo uzinzo lokusebenza kwesixhobo sesixhobo. Nangona kunjalo, ngenxa yokukhutshwa kwe-axial encinci, olu yilo luyakwazi ukunxiba kunye nokulimala phantsi kweemeko ezidlulayo.
●Umgaqo: Idisk eshukumayo ifakwe emva kwe-impeller yenqanaba lokugqibela. Umahluko woxinzelelo kuyo yonke idiski ulungelelanisa indawo yayo ukuchasana ne-axial force.
●Iingenelo: Iziqhelanisa ngokuzenzekelayo kwiiyantlukwano zamandla e-axial; ukuchaneka okuphezulu kokulinganisa.
●Iingxaki: Ukukhuhlana kubangela ukuguga, kufuna ukutshintshwa ngamaxesha athile. I-Sensitive kucoceko lolwelo (amasuntswana angenza i-disk).
●Usetyenziso: Iimpompo zamanzi acocekileyo zakwinqanaba lokuqala (ezithe ngcembe zitshintshwa ngamagubu okulinganisa).
4.Ukulinganisa iDrum + iDisk Combination
Xa kuthelekiswa nendlela ipleyiti balance, ipleyiti ibhalansi igubu indlela yahlukile ukuba ubungakanani throttle bushing inxalenye yayo mkhulu kunobukhulu hub impeller, lo gama idisc ibhalansi ifuna ubukhulu bushing throttle ukuhambelana ubungakanani hub impeller. Ngokubanzi, kwindlela yoyilo lwegubu lepleyiti yebhalansi, amandla olungelelwaniso aveliswa yi-akhawunti yeplate yebhalansi ngaphezulu kwesiqingatha samandla e-axial iyonke, kwaye ubuninzi bunokufikelela kwi-90% ye-axial force iyonke, kwaye ezinye iinxalenye zibonelelwa ikakhulu yi-balance drum. Kwangaxeshanye, ngokulinganisela ukwandisa amandla ibhalansi igubu ibhalansi uya ngokuhambelanayo ukunciphisa amandla ibhalansi ipleyiti balance, kwaye ngokuhambelanayo ukunciphisa ubungakanani ipleyiti balance, ngaloo ndlela kuncitshiswe iqondo lokunxiba ipleyiti ibhalansi, ukuphucula ubomi benkonzo amacandelo izixhobo, kunye nokuqinisekisa ukusebenza eqhelekileyo impompo centrifugal multistage.
●Umgaqo: Igubu libamba uninzi lwamandla e-axial, ngelixa idisk ilungisa amandla ashiyekileyo.
●Iingenelo: Udibanisa ukuzinza kunye nokulungelelanisa, okufanelekileyo kwiimeko zokusebenza eziguquguqukayo.
●Iingxaki: Ubume obuntsonkothileyo; ixabiso eliphezulu.
●Usetyenziso: Iimpompo zemizi-mveliso ezisebenza kakhulu (umzekelo, iimpompo zokupholisa zereactor yenyukliya).
5. I-Thrust Bearings (uNcediso loBalance)
●Umgaqo: Iibheringi zebhola e-angular okanye iibheringi ze-Kingsbury zifunxa amandla ashiyekileyo e-axial.
●Iingenelo: I-backup ethembekileyo yezinye iindlela zokulinganisa.
●Iingxaki: Ifuna ukuthanjiswa rhoqo; ubomi obufutshane phantsi kwemithwalo ephezulu ye-axial.
●Usetyenziso: Iimpompo ze-multistage ezincinci ukuya kweziphakathi okanye iimpompo zesantya esiphezulu.
6. Uyilo lwe-Impeller ephindwe kabini
●Umgaqo: I-impeller yokufunxa kabini isetyenziswe kwinqanaba lokuqala okanye eliphakathi, ukulinganisa amandla e-axial ngokusebenzisa ukungena kwamacala amabini.
●Iingenelo: Ukulinganisa okusebenzayo ngelixa uphucula ukusebenza kwe-cavitation.
●Iingxaki: Kuphela ibhalansi yenqanaba elinye amandla axial; ezinye iindlela ziyafuneka kwiimpompo zamanqanaba amaninzi.
7. Imingxunya ye-Hydraulic Balance (Imingxuma ye-Impeller Backplate)
●Umgaqo: Imingxuma igrunjwe kwi-backplate ye-impeller, evumela ukuba i-high-pressure fluid ibuyele kwindawo yoxinzelelo oluphantsi, ukunciphisa amandla e-axial.
●Iingenelo: Ilula kwaye inexabiso eliphantsi.
●Iingxaki: Ukunciphisa ukusebenza kwempompo (~ 2-4%).Ifanele kuphela izicelo eziphantsi ze-axial force; ihlala ifuna ii-thrust bearings ezongezelelweyo.
