1. I-Pump Discharge Pressure

Ingcindezi yokukhishwa kwe iphampu yeturbine ejulile eqondile ibhekisela kumandla okucindezela okuphelele (iyunithi: i-MPa) yoketshezi oluthunyelwa ngemva kokudlula empompini yamanzi. Kuyinkomba ebalulekile yokuthi ipompo ingawuqeda yini umsebenzi wokuthutha uketshezi. Ukucindezela kokukhipha kwephampu yamanzi kungase kuthinte ukuthi ukukhiqizwa komsebenzisi kungaqhubeka ngokujwayelekile yini. Ngakho-ke, ukucindezela kokukhishwa kwepompo yamanzi kuklanyelwe futhi kunqunywa ngokusekelwe ezidingweni zenqubo yangempela.

Ngokusekelwe ezidingweni zenqubo yokukhiqiza kanye nezidingo zemboni yokukhiqiza, ukucindezela kokukhipha ikakhulukazi kunezindlela zokubonisa ezilandelayo.

I-1.Ingcindezi yokusebenza evamile: Ingcindezi yokukhishwa kwepompo edingekayo lapho ibhizinisi lisebenza ngaphansi kwezimo ezijwayelekile zokusebenza.

2.Ingcindezi yokukhishwa ephezulu edingekayo: Uma izimo zokukhiqiza zebhizinisi zishintsha, izimo zokusebenza ezingase zenzeke zincike ekucindezelweni kokukhipha iphampu edingekayo.

I-3.Isilinganiso sokucindezela kokukhipha: Ingcindezi yokukhipha ecacisiwe futhi iqinisekisiwe ukuthi izozuzwa ngumkhiqizi wepompo. Ingcindezi elinganiselwe yokukhipha kufanele ilingane noma ibe mkhulu kunomfutho ojwayelekile wokusebenza. Kumaphampu ane-vane kufanele kube ingcindezi yokukhipha ekugelezeni okukhulu.

4. Ingcindezi enkulu evunyelwe yokukhipha: Inani eliphakeme elivumelekile lokucindezela kwephampu linqunywa umkhiqizi wephampu ngokusekelwe ekusebenzeni kwephampu, amandla esakhiwo, amandla ashukumisayo ayinhloko, njll. Inani eliphakeme elivumelekile lokucindezela kokukhipha kufanele libe likhulu noma lilingane ingcindezi yokukhishwa ephezulu edingekayo, kodwa kufanele ibe ngaphansi kunokucindezela okuphezulu okuvumelekile okuvumelekile kwezingxenye zokucindezela zephampu.

2. Ikhanda lephampu H

Inhloko yephampu yamanzi isho amandla atholwe ngeyunithi yesisindo soketshezi oludlulayo iphampu ye-turbine ejulile kahle. Ivezwe ngo-H, iyunithi ingu-m, okuwubude bekholomu ewuketshezi yoketshezi olukhishiwe.

Amandla asebenzayo atholakala ngemva kokucindezela kweyunithi yoketshezi edlula iphampu, eyaziwa nangokuthi ikhanda eliphelele noma ikhanda eligcwele. Singaphinde sikhulume ngomehluko wamandla phakathi koketshezi lapho kuphuma khona kanye nendawo yokungena yepompo yamanzi. Kodwa kufanele kuqashelwe: ihlobene kuphela nokusebenza kwepompo ngokwayo futhi ayihlangene nhlobo namapayipi okungena nokuphuma. Iyunithi yokuphakamisa ingubude bekholomu engu-N·m noma m.

Kumaphampu anomfutho ophezulu, umehluko wengcindezi phakathi kwepompo ne-inlet (p2-P1) kwesinye isikhathi uyalinganiselwa ukuze umele usayizi wokuphakanyiswa. Ngalesi sikhathi, i-lift H ingavezwa ngokuthi:

Kufomula, P1——ukucindezela kokuphuma kwephampu, Pa;

I-P2 ingcindezi yokungena yepompo, i-Pa;

p——ukuminyana kwamanzi, kg/m3;

g——ukusheshisa amandla adonsela phansi, m/S2.

I-Lift iyipharamitha yokusebenza eyinhloko yephampu yamanzi, esekelwe ezidingweni ze-petroleum nezinqubo zamakhemikhali kanye nezidingo zomkhiqizi wepompo.

1. Inhloko evamile yokusebenza: Ikhanda lepompo elinqunywa ukucindezela kokukhipha kanye nokucindezela kokumunca kwepompo ngaphansi kwezimo ezivamile zokukhiqiza zebhizinisi.

2. Ukuphakama okuphezulu okudingekayo ukuphakanyiswa kwepompo lapho ingcindezi enkulu yokukhipha edingekayo (ingcindezi yokudonsa ihlala ingashintshile) ishintsha lapho izimo zokukhiqiza zebhizinisi zishintsha.

3. Ikhanda elilinganiselwe Ikhanda elilinganiselwe liyinhloko yepompo yamanzi ngaphansi kobubanzi obulinganiselwe be-impeller, isivinini esilinganiselwe, ukumunca okulinganiselwe nokucindezela kokukhipha. Yikhanda elinqunywe futhi liqinisekiswe umenzi wepompo, futhi leli nani lekhanda kufanele lilingane noma libe likhulu kunekhanda elivamile elisebenzayo. Ngokuvamile, inani layo lilingana nokuphakama okuphezulu okudingekayo.

4. Ikhanda elivalayo Ikhanda elivalayo liyinhloko lapho izinga lokugeleza kwepompo yamanzi linguziro. Iwumkhawulo omkhulu wokuphakamisa iphampu yamanzi. Ngokuvamile, ingcindezi yokukhipha ngaphansi kwalokhu kuphakamisa inquma ukucindezela okuphezulu okuvunyelwe okusebenzayo kwezingxenye zokucindezela ezifana nomzimba wepompo.
