Isigaba sesine Ukusebenza kobubanzi obuguquguqukayo bephampu ye-vane
Ukusebenza kobubanzi obuguquguqukayo kusho ukusika ingxenye yesigxivizo sokuqala sepompo ye-vane ku-lathe ngobubanzi obungaphandle.Ngemva kokusikwa kwe-impeller, ukusebenza kwepompo kuzoshintsha ngokuvumelana nemithetho ethile, ngaleyo ndlela kushintshe indawo yokusebenza yepompo.
Umthetho wokusika
Phakathi kwenani elithile lokusika, ukusebenza kahle kwepompo yamanzi ngaphambi nangemuva kokusika kungathathwa njengokungaguquki.
Izinkinga ezidinga ukunakwa ekusikeni i-impeller
Kukhona umkhawulo othize enanini lokusika le-impeller, ngaphandle kwalokho isakhiwo se-impeller sizobhujiswa, futhi ukuphela kwamanzi okukhipha amanzi kuzoba mkhulu, futhi ukuvunyelwa phakathi kwe-impeller kanye ne-pump casing kuzokwanda, okuzokwenza bangela ukusebenza kahle kwepompo kwehle kakhulu.Inani eliphakeme lokusika le-impeller lihlobene nesivinini esithile.
Ukusika i-impeller yepompo yamanzi kuyindlela yokuxazulula ukungqubuzana phakathi komkhawulo wohlobo lwepompo kanye nokucaciswa kanye nokuhlukahluka kwezinto zokuhlinzeka ngamanzi, okwandisa ububanzi bokusetshenziswa kwepompo yamanzi.Ibanga elisebenzayo lepompo ngokuvamile liyingxenye yejika lapho ukusebenza kahle okuphezulu kwepompo kuncipha ngokungekho ngaphezu kuka-5% ~8% .
Isibonelo:
Imodeli: SLW50-200B
I-impeller yangaphandle ububanzi: 165 mm, ikhanda: 36m.
Uma siphendulela ububanzi obungaphandle be-impeller ku-: 155 mm
H155/H165= (155/165)2 = 0.852 = 0.88
H(155) = 36x 0.88m = 31.68m
Ukufingqa, lapho i-diameter ye-impeller yalolu hlobo lwepompo isikwa ibe ngu-155mm, ikhanda lingafinyelela ku-31 m.
Amanothi:
Ngokwenza, lapho inani lama-blades lincane, ikhanda elishintshiwe likhulu kunelo elibaliwe.
