Me pehea te whiriwhiri i te papu pai rawa atu

2BAR PAPU

Puma wai makariri:

He taputapu e turaki ana i te wai ki te huri haere i roto i te kohanga wai makariri.E mohio ana tatou, ko te mutunga o te rūma whakamahana hau (penei i te powhiri powhiri, te waahanga maimoatanga hau, me etahi atu) e hiahia ana ki te wai matao e whakaratohia ana e te kaitao, engari kaore te wai makariri e rere noa na te aukati o te aukati, e hiahia ana. te papu ki te pei i te wai makariri ki te huri haere ki te whakatutuki i te kaupapa o te whakawhiti wera.

 

papu wai whakamatao:

He taputapu e turaki ana i te wai ki te huri haere i roto i te kohanga wai whakamatao.E mohio ana tatou, ka tangohia e te wai whakamatao etahi wera mai i te pouaka whakamatao i muri i te urunga ki roto i te whakamatao, katahi ka rere ki te pourewa whakamatao ki te tuku i tenei wera.Ko te papu wai whakamahana te kawenga mo te taraiwa i te wai whakamatao kia huri haere i roto i te katinga kati i waenga i te waahanga me te pourewa whakamatao.He rite te ahua ki te papu wai makariri.

Hoahoa ara wai

Puma tuku wai:

Ko te taputapu whakakii wai whakaahuru, he kawenga mo te maimoatanga o te wai ngawari ki roto i te punaha.He rite te ahua ki te papu wai o runga.Ko nga papua e whakamahia nuitia ana ko te papu centrifugal whakapae me te papu centrifugal poutū, ka taea te whakamahi i roto i te punaha wai makariri, te punaha wai whakamatao me te punaha whakakii wai.Ka taea te whakamahi i te papu centrifugal whakapae mo te waahi ruuma nui, ka taea te whakaaro te papu centrifugal poutū mo te waahi ruma iti.

 

Whakataki ki te tauira papu wai, hei tauira, 250RK480-30-W2

250: te diameter kokoru 250 (mm);

RK: te whakamahana me te whakamahana hau e rere ana te papu;

480: tohu rerenga hoahoa 480m3/h;

30: tohu pane hoahoa 30m;

W2: Momo whakapuru papu.

Ka kitea mai i te ripanga i runga ake nei: ka rere whakarara te papu wai, ka iti haere te rere o te rere;Ina neke ake te maha o nga teihana whakarara i te 3, ka tino kaha te whakaheke.

 

E whakaarohia ana kia:

1, te kōwhiringa o papua maha, ki te whakaaro i te attenuation o te rere, te tikanga atu 5% ~ 10% tawhē.

2. Ko te papu wai kia kaua e neke ake i te 3 huinga i roto i te whakarara, ara, kaua e neke ake i te 3 huinga ina kowhiria te ope whakamatao.

3, me whakatu nga kaupapa nui me te reo-rahi, nga papu tohanga wai makariri me te wera

 

I te nuinga o te waa, ko te maha o nga papu wai makariri me nga papu wai whakamatao kia rite ki te maha o nga kaihautu whakamatao, a me whakamahi tetahi hei taapiri.I te nuinga o te waa ka tohua te papu wai i runga i te kaupapa o te whakamahi kotahi me te taapiri kotahi hei whakarite i te tuku wai pono o te punaha.

Ko nga papa ingoa papu e tohuhia ana ki nga tawhā penei i te rere whakatau me te upoko (tirohia te papa ingoa papu).A, no te whiriwhiri tatou i te papu, e ti'a ia tatou ki te tuatahi te whakatau i te rere me te upoko o te papu, a ka whakatau i te papu hāngai rite ki te whakaritenga tāutanga me te āhuatanga pae.

 

(1) tātai tātai rere o te papu wai mātao me te papu wai whakamatao:

L (m3/h) =Q(Kw)×(1.15~1.2)/(5℃×1.163)

Q- Te kaha whakamahana o te kaihautu, Kw;

L- Te rere o te papu wai whakamatao, m3/h.

 

(2) Te rere o te papu tuku:

Ko te 1% ~ 2% o te rōrahi wai huri noa o te punaha.Heoi, i te wa e whiriwhiri ana i te papu tuku, kia kore e tutuki noa te rere o te papu tuku ki te rahinga o te wai whakangao noa o te punaha wai o runga ake nei, engari me whakaaro ano hoki ki te pikinga o te wai recharge i te wa ka pa he aitua.Na reira, ko te rere o te papu tuku ko te nuinga o te waa kaua e iti iho i te 4 nga wa o te nui o te wai recharge.

Ka taea te whakaaro te rōrahi whai hua o te tank supply wai rite ki te supply wai noa o 1 ~ 1.5h.

 

(3) Te hanganga o te upoko papu wai makariri:

Atete wai whakaeo o te wae whakamatao: te tikanga 5~7mH2O;(Tirohia te tauira hua mo nga taipitopito)

Taputapu Whakamutunga (wae whakahaere hau, poroporo powhiri, me etahi atu) whakamatao teepu, whakaeto wai ranei: te tikanga 5~7mH2O;(Tena koa tirohia te tauira hua mo nga uara motuhake)

 

Ko te ātete o te tātari wai tuara, e rua-ara whakahaere takirere, me etahi atu, ko te tikanga 3~5mH2O;

He whakawehe wai, he kaikohi wai te parenga wai: te tikanga he 3mH2O;

putorino wai pūnaha mātao haere te ātete me te mate ātete rohe: te tikanga 7~10mH2O;

Hei whakarāpopoto, ko te upoko o te papu wai mātao ko 26~35mH2O, te tikanga 32~36mH2O.

Kia mahara: ko te tatauranga o te upoko me noho ki runga i te ahuatanga motuhake o te punaha whakamatao, kaore e taea te kape i te uara wheako!

 

(4) Te tito o te upoko papu whakamahana:

Atete wai condenser o te wae whakamatao: te tikanga 5~7mH2O;(Tena koa tirohia te tauira hua mo nga uara motuhake)

Te pehanga rehu: te tikanga 2~3mH2O;

Te rerekētanga teitei i waenganui i te paepae wai me te pupuha o te pourewa meangiti (tuwhera te meangiti pourewa): te tikanga 2~3mH2O;

 

Ko te ātete o te tātari wai tuara, e rua-ara whakahaere takirere, me etahi atu, ko te tikanga 3~5mH2O;

Pūnaha whakamahana paipa wai i te taha o te parenga me te mate ātete rohe: te tikanga 5~8mH2O;

Hei whakarāpopoto, ko te upoko papu whakamahana ko 17~26mH2O, te tikanga 21~25mH2O.

 

(5) upoko papu whangai:

Ko te upoko te upoko taonga o te tawhiti i waenga i te ira pehanga tonu me te tohu teitei + te parenga o te pito momi me te pito putanga o te papu +3 ~ 5mH2O.
