Ngokubanzi, qala iimpompo ye-centrifugal, ngokweenkcukacha kufuneka, igumbi lokuqala lokumpompa lizaliswe ngophakathi, vala ivalve yokuphuma, emva koko uvuleimpompo, injongo kukuba: kwelinye icala ukukhusela ukuqala kwangoku kumonakalo omkhulu kakhulu kwi-motor;Kwelinye icala, kuthintele ilahleko ngoko nangoko yoxinzelelo emva kokuqalaimpompo, iphumela kwiimpompoi-cavitation.Kodwa iingxaki ezininzi azinakwenziwa ngokubanzi!
Ukuhamba okuphantsi kunye nentloko ephantsiiimpompo, ukuvala okanye ukuvala ivalve yokuphuma akuyona ingxaki.
Ngokuba enkuluiimpompo, i-outlet ivame ukuvulwa kancinci ukukhusela ukuhlukana koxinzelelo phakathi kwangaphambili nasemva kwevalve emva kokuqala, kwaye i-valve yokuphuma ayilula ukuyivula, ngoko ke ukuvulwa kwe-valve yokuphuma kuvulwa kancane.
Abanyeiimpompo ze-centrifugaliya kuvula kancinane ivalve yokuphuma ngenxa yokufudumeza kwangaphambili kunye nezinye iimfuno.
Ukuba ikunye nokufunxa, ukuvala ngokupheleleyo ivalve yokuphuma, kwaye uvule ivalve (hayi self-priming pump), kodwa uvule nevalve yokukhupha impompo.
Kwezinye iimeko ezikhethekileyo, ivalve yokuphuma ayinakuvulwa, umzekelo, ipropylene yolwelo, ukuba ivalve yokuphuma ivula kuqala, ipropylene iyaphuphuma, impompo ayiyi kukwazi ukunyanzeliswa, ngoko kufuneka ivalwe kuqala, impompe kwaye uze uvule ngokukhawuleza ivalve yokuphuma.
Ezi zingasentla ziimpompo ze-centrifugal.Kwezinye iintlobo zeempompo, imeko ilandelayo:
1. Iimpawu ezinkulu zokuqalisa ukuqukuqela kwempompo ye-axial-ivalve evuleke ngokupheleleyo
Amandla e-shaft ye-axial flowimpompolelona likhulu kwimo ye-zero flow, eyi-140 % ~ 200 % yamandla alinganisiweyo eshaft, kwaye amandla ngawona mancinci kwinqanaba lokuhamba okuphezulu.Ngoko ke, ukuze kuncitshiswe ukuqala kwangoku, iimpawu zokuqala zamandla e-shaft kufuneka zibe yisiqalo esikhulu sokuhamba (oko kukuthi, ukuqala kwevalve evulekile ngokupheleleyo).
2. Iimpawu zokuqalisa zompompo oxutyiweyo-i-valve evule ngokupheleleyo ukuqalisa
Amandla e-shaft ye-mix-flowimpompokwimeko yokuhamba kuka-zero iphakathi kwezi zimbini zingasentlaiimpompo, eyi-100 % ~ 130 % yamandla alinganisiweyo.Ngoko ke, iimpawu zokuqala zempompo edibeneyo kufuneka ibe phakathi kwezi zimbini zingentlaiimpompo, kwaye kungcono ukuqala ngokuvula ivalve epheleleyo.
3. Iimpawu zokuqalisa zempompo ye-vortex-i-valve evule ngokupheleleyo ukuqalisa
Amandla e-shaft ye-vorteximpompolelona likhulu kwimo ye-zero flow, eyi-130 % ~ 190 % yamandla alinganisiweyo eshaft.Ngoko ke, kufana nokuhamba kwe-axialimpompo, iimpawu zokuqalisa zempompo ye-vortex kufuneka ibe yisiqalo esikhulu sokuhamba ( oko kukuthi, ukuqala kwevalve epheleleyo).
