1. Uxinzelelo lwePump Discharge

Uxinzelelo lokukhupha lwe impompo yeinjini yomoya ethe nkqo ibhekisa kumandla oxinzelelo lulonke (iyunithi: MPa) yolwelo oluthunyelwa emva kokudlula kwimpompo yamanzi. Luphawu olubalulekileyo lokuba ipompo inokugqiba umsebenzi wokuthutha ulwelo. Uxinzelelo lokukhupha lwempompo yamanzi lunokuchaphazela ukuba imveliso yomsebenzisi inokuqhubeka ngokuqhelekileyo. Ngoko ke, uxinzelelo lokukhutshwa kompompo wamanzi luyilwe kwaye lunqunywe ngokusekelwe kwiimfuno zenkqubo yangempela.

Ngokusekelwe kwiimfuno zenkqubo yokuvelisa kunye neemfuno zesityalo sokuvelisa, uxinzelelo lokukhutshwa luneendlela zokubonisa ezilandelayo.

I-1.Uxinzelelo oluqhelekileyo lokusebenza: Uxinzelelo olufunekayo lwepompo lokukhupha xa ishishini lisebenza phantsi kweemeko eziqhelekileyo zokusebenza.

I-2.Uxinzelelo oluphezulu olufunekayo lokukhupha: Xa iimeko zokuvelisa ishishini zitshintsha, iimeko zokusebenza ezinokuthi zenzeke zixhomekeke kuxinzelelo olufunekayo lokukhupha impompo.

I-3.Uxinzelelo lokukhupha olulinganisiweyo: Uxinzelelo lokukhupha oluchazwe kwaye luqinisekisiwe ukuba lufezekiswe ngumenzi wempompo. Uxinzelelo lokukhupha olulinganisiweyo kufuneka lulingane okanye lube lukhulu kunoxinzelelo oluqhelekileyo lokusebenza. Kwiimpompo ze-vane kufuneka ibe luxinzelelo lokukhupha ukuhamba okuphezulu.

4. Ubuninzi obuvumelekileyo bokukhutshwa koxinzelelo: Ubuninzi obuvumelekileyo bexabiso loxinzelelo lwempompo lumiselwa ngumenzi wempompo ngokusekelwe ekusebenzeni kwempompo, amandla okwakhiwa, amandla ahamba phambili, njl njl. Uxinzelelo oluphezulu olufunekayo lokukhupha, kodwa kufuneka lube ngaphantsi koxinzelelo oluvumelekileyo oluvumelekileyo lwamacandelo oxinzelelo lwempompo.

2. Intloko yempompo H

Intloko yempompo yamanzi ibhekisa kumandla azuzwe ngobunzima beyunithi yolwelo oludlula kwi impompo yeinjini yomoya enzulu kakuhle. Ivakaliswe ngu-H, iyunithi ngu-m, obubude boluhlu lolwelo olukhutshiweyo.

Amandla asebenzayo afunyenwe emva koxinzelelo lweyunithi yolwelo ludlula kwimpompo, eyaziwa ngokuba yintloko epheleleyo okanye intloko epheleleyo. Sisenokuthetha kwakhona ngomahluko wamandla phakathi kolwelo kwindawo yokuphuma kunye nendawo yokungena yempompo yamanzi. Kodwa kufuneka kuqatshelwe: ihambelana kuphela nokusebenza kwempompo ngokwayo kwaye ayinanto yokwenza nemibhobho yokungena kunye nokuphuma. Iyunithi yokuphakamisa yi-N·m okanye m ubude bekholamu yolwelo.

Kwiimpompo zoxinzelelo oluphezulu, ukuhlukana koxinzelelo phakathi kwepompo kunye ne-inlet (p2-P1) ngamanye amaxesha kuqikelelwa ukumela ubungakanani bokunyusa. Ngeli xesha, ukuphakama H kunokubonakaliswa ngolu hlobo:

Kwifomula, i-P1--uxinzelelo lokuphuma kwempompo, i-Pa;

I-P2 yingcinezelo yokungena kwempompo, i-Pa;

p——ukuxinana kolwelo, kg/m3;

g——isantya somxhuzulane, m/S2.

Ukuphakamisa iparameter yokusebenza ephambili yepompo yamanzi, esekelwe kwiimfuno zepetroleum kunye neenkqubo zemichiza kunye neemfuno zomenzi wempompo.

1. Intloko yokusebenza eqhelekileyo: Intloko yempompo inqunywe ngoxinzelelo lokukhutshwa kunye noxinzelelo lokufunxa lwempompo phantsi kweemeko eziqhelekileyo zokuvelisa zeshishini.

2. Ukuphakama okuphezulu okufunekayo kukuphakanyiswa kwempompo xa ubuninzi obufunekayo uxinzelelo lokukhupha (uxinzelelo lokufunxa luhlala lungatshintshi) lutshintsha xa iimeko zokuvelisa ishishini zitshintsha.

3. Intloko elinganisiweyo Intloko yempompo yamanzi phantsi kwedayamitha ye-impeller elinganisiweyo, isantya esilinganiselweyo, isantya sokufunxa kunye noxinzelelo lokukhupha. Iyintloko enqunywe kwaye iqinisekiswe ngumenzi wempompo, kwaye eli xabiso lentloko kufuneka lilingane okanye likhulu kunentloko yokusebenza eqhelekileyo. Ngokuqhelekileyo, ixabiso layo lilingana nokuphakama okuphezulu okufunekayo.

4. Intloko yokuvala Intloko yokuvala yintloko xa isantya sokuhamba kwempompo yamanzi ingu-zero. Yeyona nto iphakamileyo yokunyuswa kwempompo yamanzi. Ngokuqhelekileyo, ukunyanzeliswa kokukhutshwa phantsi kwesi siphakamiso sinquma ubuninzi obuvumelekileyo bokusebenza uxinzelelo lwamacandelo oxinzelelo njengomzimba wempompo.
