Izixhobo kunye siseko amanyathelo kweempompo centrifugal. Classification, iimpawu

Ukuba sicinga izixhobo ezisetyenziswa zokumpompa ulwelo, elula kakhulu nempompo centrifugal. Le mishini yokusebenza eliphezulu kwaye sibonelela ingcinezelo enamandla, kodwa design kuzo zonke iimpawu ezintle elula kakhulu. iindawo zokumpompa kunye iimpompo indlu asetyenziswa lombutho yonikezelo lwamanzi elizenzekelayo ukwenzela unkcenkceshelo okanye ipoma iindawo, ningabaleli hlobo.

izixhobo pump

Uyilo kunye nokusebenza iimpompo centrifugal ziza kuchazwa kwinqaku. Ukuba sicinga inxalenye yokuqala umbuzo, kunokwenzeka ukugxininisa ukuba isiqalelo yokusebenza uyilo elula iquka omzimba elijongeka njengenkumba okanye saya. Ngaphakathi kukho umngxuma kunye impeller, owokugqibela apho Iqinisekile kanye kwizikhondo. Key edlulisela njengokujikeleza nomphini ukuya ivili. Le impeller ubunjwe IiCD amabini kunye iincakuba, leyo ayinakutshintshwa phakathi kwabo.

Yabe babe imilo egosogoso kwaye eveleleyo kwicala ubuso kwicala ejikelezayo. Ukuba unomdla iimpawu iimpompo centrifugal, ufanele wazi ukuba umzimba wenziwe elingqukuva ngentsimbi okanye intsimbi, kodwa impellers ukuba yakhiwe neeplastikhi. impeller shaft ngokweendlela ezahlukeneyo evaliweyo okanye isibili. Kwimeko yokugqibela wayo zincediswe iibheringi. Ukuya ngaphaya izindlu kunye nokuthetha kunye plane oluthi ngogesi cranked okanye nge kokubonisa izenzo shank njengoko actuator.

Ukuze kuthintelwe ukuvuza umbandela ampontshwe Ekungeneni kwi izindlu, isakhiwo itywina sinikezwe.

yobunzima oluthembekileyo

Ukuba unomdla isixhobo kunye nokusebenza kweempompo centrifugal, kungcono ngexesha lokuthenga ukuba zincede zikhethe enye into eye umngxuma ngetywina ngoomatshini. Olu khetho ukuba ukuthembeka ngaphezu le bhokisi Akunakuba, ngelo xesha sele ingqalelo lixesha. uphawu Mechanical iqinisekisa yengxinano olupheleleyo izindlu nkqu kwimeko apho shaft impeller ishenxiselwe. ukuthembeka High liqinisekisiwe kwaye intlokoma, leyo ukuthintelwa ngexesha nokusebenza impompo.

isimiso ukusebenza

Emva kokuba isixhobo kunye yokusebenza siseko iimpompo centrifugal ziya makwazeke kuwe, unako ukuthenga izixhobo ze uqale ukuyifaka. Kodwa ke, ngaphambi koko, kufuneka baqhelane noko siseko yokusetyenziswa oluchazwe. Ngoko ke, emva kokuba injini iqale, oluthi pump iqalisa ukuba uphendule. Iincakuba isondo actuated kweziyobisi egumbini ukusebenza. Ulwelo iqala ukuya kwisangqa, yokuxhayelwa kwabo amandla centrifugal. Imodyuli ye la mandla uya kuba mkhulu phezu molekyuli eliphakathi ampontshwa iza kuba kwiziko ujikelezo. Ekugqibeleni, lo amanzi betekisi kwi kwimida impeller, ngoko ke uya iplagi. Oku kuqinisekisa ukuba uxinzelelo ngenxa amandla centrifugal.

Classification ngokwenani izigaba

Ukuze senze ukhetho olufanelekileyo izixhobo, kufuneka ukwazi isixhobo nangemigaqo kweempompo centrifugal. Oku kusebenza kwi yokuhlela. Yahlula iiyunithi kuba ngezizathu eziliqela, kuquka kwinani izigaba. Izicwangciso kuba omnye eqongeni kunye multi-eqongeni. Kwimeko yokuqala isakhiwo ifakiwe impeller omnye kuphela, le nkqubo yamandulo. Ukuba kukho imfuneko yokuphuhlisa koxinzelelo olukhulu, ukuba usebenzisa iimpompo multistage, apho impellers eziliqela ezinyuselwe shaft enye. Umgaqo ukusebenza kwalo sixhobo kuxhomekeke kwinto yokuba yevili ngalinye kwigumbi esebenza esakha nyathelo. Izindlu ihleliwe ukuze kulwelo sidluliselwa ibakala omnye komnye yonke imihla xa lufikelela iplagi.

Classification ngokuqondisa esqwini ujikelezo

Ukuba unomdla iimpawu iimpompo centrifugal, kufuneka kuqala ukhethe izinto okanye ezinye izixhobo apho eklasini. Zingaba kwabiwa kwakhona kwicala esqwini ujikelezo. Oku kubonisa ukuba shaft banokuba ngokuxwesileyo okanye nkqo.

Nemeko yokuqala yeyona ixhaphakileyo, ngenxa lula yesondlo. Uhlobo lwesibini lubandakanya isithuba ngaphantsi ukuze ukufakwa, kususela injini ibekwe phantsi wenqanawa. Olu hlobo ekunokuthiwa ezininzi iimpompo ngwenya, leyo luyilwe ukusebenza kwiimeko emxinwa. Ezinjalo centrifugal pump ukwenzela amaqula babe ethile omnye, nto leyo ichazwe kwi kukuba kugcinwe okanye ukulungiswa kwezindlu kuya kufuneka ukususa injini.

Ulwahlulo indlela kweempompo lokufaka kunye neempawu zazo

On sale centrifugal kwimizi iimpompo kuluhlu olubanzi, nokuba bohluka enye kwenye indlela yofakelo. Kuxhomekeka neenjongo ezimiselwe ukuba izixhobo kunye nemiqathango yokusetyenziswa, khetha umphezulu, semi-ngwenya okanye ngwenya pump. umthombo Surface ibekwe ngqo ecaleni okanye umgama ukusuka kulo. Hlawula for eso sixhobo iza kuba ngaphantsi. Ifowuni iza kuhlala ebonakalayo, ebonisa ukuba ukufikelela lula ulondolozo kunye nokuhlola. A nokubi iphumele imeko phantsi apho inqanaba amanzi kumthombo kufuneka abe okanye ngaphezulu kwiimitha 8 kwinqanaba isalamane unit setting. Ngako oko ke kunye equleni kunye nemithombo, loo nezezixhobo zokusebenza aziyi kusebenza.

Iimpawu kunye iimpompo ngwenya semisubmersible

Ucinga iimpompo industrial, uqinisekile ukuba anikele ingqalelo imodeli ngwenya, apho shaft nkqo. Ezinye ilungu lomzimba egxile kuloo mthombo, amaxesha amaninzi izixhobo ezisetyenziswa sokumpompa ulwelo evela kuloo mihadi. Xa kukho imfuneko yokumpompa amanzi equleni kunye nemithombo, iimpompo ngwenya asetyenziswa, leyo ngexesha umsebenzi ebhatalwa kwi-chain okanye ucingo.

Isixhobo ukuba ukuntywiliselwa ngokupheleleyo emanzini. Ngenxa yokuba ukusebenza kwezi mpompo centrifugal i ngwenya udidi lukhatshwa kukungakhuseleki kumzimba bume ndlongondlongo, kufuneka babe neempawu ezithile, phakathi leyo - le nokumelana langaphandle isakhiwo, ngokulitywina ityala kunye namalungu zombane, kunye nokuthintela amathuba ukuvuza yeoli injini kulwakhiwo pump. Imfuneko yokugqibela ibaluleke kakhulu, kuba xa engena iqula okanye oyile isitsala injini, susa bekuya kuba nzima kakhulu kwaye iyabiza.

iimpompo Classification for indlela yokutsala amanzi, kunye neempawu kwezixhobo

centrifugal Performance yokumpompa iya kuxhomekeka umthamo injini, lo msebenzi osemqoka unokuba zifumaneka kwiphepha data isixhobo. Kufuneka ukugcina imali ngokuthenga iyunithi kunye ubuncinane sikhundla, njengoko kulo mzekelo, phantsi izixhobo umthwalo onzima ziya kusebenza ukunxiba. Nangona kunjalo, olu khetho yenye yezinto ezibalulekileyo xa ukhetha. Kufuneka uhlawule phambi lithenga kwaye ngoko ukusebenzisa amanzi ngendlela wasebenzisa indlela ethile. scheme yokumpompa centrifugal iya kuvumela ukuba uyakuqonda oko maqela design, oku kubaluleke ngakumbi xa umsebenzi wofakelo eniyivelisayo ngokwakho. Kufuneka ukuba siyiqonde ngakumbi yaye ke yintoni na Izixhobo: pump sokufunxa eqhelekileyo okanye isixhobo self-priming.

Kwimeko yokuqala, amanzi ahamba nge womxhuzulane, lo gama imodeli self-priming ziya kuba nako phakamisa amanzi ukuya kubunzulu ethile. Njengoko practice ibonisa, lo parameter ngaphantsi kweemitha-8.
