Njengesixhobo esisetyenziswa ngokubanzi kwintsimi yonyango lwamanzi oshishino kunye noluntu, ukusebenza kwe impompo yokufunxa kabini ityala inxulumene ngokuthe ngqo nokusebenza kakuhle kunye noqoqosho lwenkqubo. Ngokutolika ngokunzulu le mijelo yokusebenza, abasebenzisi banokwenza ukhetho olufanelekileyo ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuthembeka kwempompo.

Igophe lokusebenza lompompo lihlala liqulethe iiparitha ezininzi eziphambili ukunceda abasebenzisi baqonde ukusebenza kwempompo kwaye bakhethe impompo efanelekileyo. Ngokusekwe kumzobo owunikileyo, sinokutolika ezinye zeeparamitha eziphambili kunye neentsingiselo zegophe:

1. I-X-axis (umlinganiselo wokuhamba Q)

Izinga lokuqukuqela (Q): I-axis ethe tye yegrafu imele ireyithi yokuhamba nge-m³/h. Ngokuqhelekileyo, okukhona umlinganiselo wokuqukuqela mkhulu, kokukhona umthamo wokukhupha umpompo mkhulu. Ngokuqhelekileyo le axis iyanda ukusuka ekhohlo ukuya ekunene.

2. Umgca ongu-Y (intloko H)

Intloko (H): I-axis ethe nkqo yegrafu imele intloko kwiimitha (m). Intloko ibonisa ukuphakama apho umpompo unokuphakamisa ulwelo, olu luphawu olubalulekileyo lokulinganisa umthamo wempompo.

3. Imigca elinganayo

Imigca eyi-equi-head lines: Imigca egobileyo kumfanekiso yimigca elinganayo-entloko, ngamnye ebonisa ixabiso lentloko ethile (njenge-20m, 50m, njl.). Le migca imele intloko enokuthi ipompo impompo ibonelele ngamazinga ahlukeneyo okuhamba.

4. Iigophe ezisebenzayo

Iigophe ezisebenzayo: Nangona i-curve nganye esebenzayo ingaboniswa ngokuthe ngqo kulo mzobo, kwigrafu ye-curve yokusebenza eqhelekileyo, ngokuqhelekileyo kukho i-curve (η) esetyenziselwa ukubonisa ukusebenza kwempompo. Ezi ngqungquthela zibonisa ukusebenza kakuhle kwempompo kwinqanaba lokuhamba elihambelanayo, ngokuqhelekileyo libonakaliswa njengepesenti. Ezinye iigrafu zisebenzisa imibala eyahlukeneyo okanye iindidi zemigca ukwahlula.

5. Uluhlu lokusebenza

Uluhlu olusebenzayo: Ngokujonga imigca yentloko elinganayo kwigrafu, uluhlu olusebenzayo lwe impompo yokufunxa kabini ityala inokumiselwa. Ngokufanelekileyo, indawo yokusebenza (i-intersection of flow and head) kufuneka ibe phakathi kwemigca yentloko kwaye isondele kwindawo ephezulu (BEP) yomgca osebenzayo ngokusemandleni.

6. Amandla ehashe namandla

Iimfuno zamandla: Nangona le grafu igxininisa ulwazi malunga nokuhamba kunye nentloko, kwizicelo zangempela, i-curve yamandla ingasetyenziselwa ukuqonda amandla okufakwayo afunekayo ukuze kusebenze ipompo kwizinga elithile lokuhamba.

7. Imizekelo yegophe

Iigophe zeemodeli ezahlukeneyo: Ngokuxhomekeke kwimodeli yempompo kunye noyilo, kuya kubakho iijika zentloko ezilinganayo ezahlukeneyo. Ezi ngqungquthela ziphawulwe ngokubanzi ngeentlobo ezahlukeneyo zomgca ukuququzelela ulwahlulo lokusebenza phantsi kweemodeli ezahlukeneyo okanye iimeko zoyilo ezahlukeneyo.

8. Iimeko ezikhethekileyo

Amanqaku okusebenza akhethekileyo angaboniswa kwigrafu ukubonisa iimpawu zokusebenza phantsi komthwalo othile okanye iimeko zenkqubo, ebaluleke kakhulu ekukhethweni kwizicelo zobunjineli zangempela.

Ubungakanani bomsebenzi wegophe ityala lokwahlula impompo yokufunxa kabini inemisebenzi ephambili ilandelayo:

1. Uvandlakanyo lwentsebenzo

Isantya sokuhamba kunye nobudlelwane bentloko: I-curve ingabonisa intuitively ubudlelwane phakathi kwezinga lokuhamba kunye nentloko, ukunceda abasebenzisi baqonde amandla okusebenza kompompo phantsi kweemeko ezahlukeneyo zomthwalo.

2. Uhlalutyo olusebenzayo

Ukuchongwa kweyona ndawo isebenzayo (BEP): Eyona ndawo isebenzayo idla ngokuphawulwa kwigrafu, kwaye abasebenzisi banokusebenzisa eli nqaku ukukhetha uluhlu olusebenzayo lwempompo ukufezekisa amandla afanelekileyo kunye noqoqosho.

3. Ukutshatisa inkqubo

Ukuhambelana komthwalo: Ngokudityaniswa neemfuno zenkqubo, ivumela abasebenzisi ukuba bafumane uhlobo lwempompo olufanelekileyo kwisicelo sabo esithile (njengokubonelela ngamanzi, ukunkcenkceshela, inkqubo yoshishino, njl.).

4. Ukukhetha impompo

Ukuthelekisa kunye nokukhetha: Abasebenzisi banokuthelekisa iintlobo ezahlukeneyo zeempompo ngokusebenzisa i-curves yokusebenza ukukhetha ipompo kunye nokusebenza kakuhle.

5. Ukhuseleko lokusebenza

Gwema i-cavitation: I-curve inokunceda ekuvavanyeni ukuphakama kwe-suction positive inet (NPSH), inceda ukukhusela i-cavitation kunye nezinye iingxaki, kunye nokuphucula ukusebenza okukhuselekileyo kwempompo.

6. Iimfuno zamandla

Ukubala kwamandla: Ibonisa amandla okufakwayo afunekayo kumazinga ahlukeneyo okuhamba, okuvumela abasebenzisi ukuba benze uhlahlo lwabiwo-mali lwamandla kunye noyilo lwenkqubo.

7. Isikhokelo sokugunyazisa kunye nokugcinwa

Ukuxazulula iingxaki: Ngokuthelekisa kunye nesigxina sokusebenza, abasebenzi kunye nokugcinwa kwabasebenzi banokukhawuleza ukugqiba ukuba ipompo isebenza ngokuqhelekileyo, nokuba kukho naziphi na iimpazamo okanye iingxaki zokunciphisa ukusebenza kakuhle.

8. Ukulungiswa kwenkqubo

Ulawulo oluchanekileyo: Ngokusebenzisa i-curve yokusebenza, abasebenzisi banokwandisa uyilo lwenkqubo ukuqinisekisa ukuba impompo isesona simo sokusebenza.

isiphelo

I-spectrum ye-curve spectrum sisixhobo esiyimfuneko esenzela abasebenzisi ukuba baqonde ngokucacileyo iimpawu zokusebenza ze-split case impompo yokufunxa kabini, kodwa inika isiseko esibalulekileyo soyilo lwenkqubo kunye nokusebenza kakuhle. Ngokuhlalutya ngokwesayensi kunye nengqiqo kunye nokusebenzisa ezi ngqungquthela, abasebenzisi abakwazi ukukhetha kuphela uhlobo lwempompo olungcono, kodwa bakhulise amandla okusebenza kakuhle, ukunciphisa iindleko zokugcinwa, kunye nokwandisa ubomi benkonzo yezixhobo ngexesha lokusebenza.
