1. Kuthamanga kwa Pampu

Kutulutsa kuthamanga kwa pampu yakuya yoyimirira ya turbine kutanthauza mphamvu yamphamvu yonse (gawo: MPa) yamadzimadzi omwe amatumizidwa pambuyo podutsa mpope wamadzi. Ndichizindikiro chofunikira chosonyeza ngati pampu imatha kumaliza ntchito yonyamula madzi. Kuthamanga kwa pampu yamadzi kumatha kukhudza ngati kupanga kwa wogwiritsa ntchito kumatha kuchitika moyenera. Choncho, kuthamanga kwa madzi a pampu yamadzi kumapangidwira ndikutsimikiziridwa malinga ndi zosowa za ndondomeko yeniyeni.

Malingana ndi zofunikira za ndondomeko yopangira zinthu komanso zofunikira za malo opangira zinthu, kupanikizika kwa kutulutsa makamaka kumakhala ndi njira zowonetsera zotsatirazi.

1.Kuthamanga kwanthawi zonse: Kuthamanga kwapampu komwe kumafunikira pamene bizinesi ikugwira ntchito mokhazikika.

2.Kuthamanga kwakukulu kumafunika kutulutsa: Pamene zochitika zamakampani zimasintha, ntchito zomwe zingachitike zimadalira mphamvu yotulutsa pampu yofunikira.

Kuthamanga kwa 3.Kuthamanga kwazitsulo: Kuthamanga kwazitsulo komwe kumatchulidwa ndikutsimikiziridwa kuti kukwaniritsidwa ndi wopanga mpope. Kuthamanga koyezera kotulutsa kuyenera kukhala kofanana kapena kukulirapo kuposa kuthamanga kwanthawi zonse. Kwa mapampu a vanene kuyenera kukhala kuthamanga kwambiri pakutulutsa.

4. Kuthamanga kwakukulu kololedwa kutulutsa: Kuthamanga kwakukulu kovomerezeka kwa mpope kumatsimikiziridwa ndi wopanga mpope potengera momwe mpope amagwirira ntchito, mphamvu zamapangidwe, mphamvu zoyendetsera mphamvu, ndi zina zotero. Kuthamanga kwakukulu komwe kumafunikira kutulutsa, koma kuyenera kukhala kotsika kuposa kukakamiza kovomerezeka kovomerezeka kwa zigawo zapampopi.

2. Pampu mutu H

Mutu wa mpope wamadzi umatanthawuza mphamvu yopezedwa ndi yuniti yamadzimadzi yomwe imadutsa pampu yakuya ya turbine yakuya bwino. Kufotokozedwa ndi H, unit ndi m, womwe ndi kutalika kwa mzere wamadzimadzi wamadzimadzi otulutsidwa.

Mphamvu yogwira mtima yomwe imapezeka pambuyo pa mphamvu ya unit yamadzimadzi imadutsa pampu, yomwe imadziwikanso kuti mutu wonse kapena mutu wonse. Titha kulankhulanso za kusiyana kwa mphamvu pakati pa madzi omwe amatuluka ndi polowera madzi. Koma ziyenera kuzindikirika: zimangogwirizana ndi magwiridwe antchito a mpope wokha ndipo alibe chochita ndi mapaipi olowera ndi kutulutsa. Malo okwera ndi N·m kapena m kutalika kwa mzere wamadzimadzi.

Kwa mapampu othamanga kwambiri, kusiyana kwapakati pakati pa mpope ndi polowera (p2-P1) nthawi zina kumayerekezedwa kuyimira kukula kwake. Panthawiyi, kukweza H kungafotokozedwe motere:

Mwachidule, P1——kuthamanga kwa mpope, Pa;

P2 ndiye kuthamanga kwa mpope, Pa;

p——kuchulukira kwamadzi, kg/m3;

g——kuthamanga kwa mphamvu yokoka, m/S2.

Kukweza ndi gawo lofunikira la pampu yamadzi, yomwe imachokera ku zosowa za mafuta ndi mankhwala ndi zofunikira za wopanga mpope.

1. Mutu wanthawi zonse: Mutu wapampu umatsimikiziridwa ndi kuthamanga kwa kutulutsa ndi kukakamiza kwa pampu pansi pamikhalidwe yabwinobwino yopanga bizinesi.

2. Kukweza kwakukulu komwe kumafunikira ndikukweza kwa mpope pamene kupanikizika kwakukulu komwe kumafunika kutulutsa (kuthamanga kwa suction kumakhalabe kosasintha) kumasintha pamene zochitika zamakampani zimasintha.

3. Mutu wovoteledwa Mutu wovoteledwa ndi mutu wa mpope wamadzi pansi pa chiwongolero chowongolera, kuthamanga kwake, kuvotera kuyamwa ndi kuthamanga kwamadzi. Ndi mutu womwe umatsimikiziridwa ndikutsimikiziridwa ndi wopanga mpope, ndipo mtengo wamutuwu uyenera kukhala wofanana kapena wokulirapo kuposa mutu wamba. Nthawi zambiri, mtengo wake ndi wofanana ndi kukweza kwakukulu komwe kumafunikira.

4. Kutseka mutu Mutu wotseka ndi mutu pamene kuthamanga kwa mpope wamadzi ndi ziro. Ndilo malire okweza pampu yamadzi. Nthawi zambiri, kupanikizika kotulutsa pansi pa kukweza kumeneku kumatsimikizira kukakamizidwa kovomerezeka kovomerezeka kwa zigawo zokakamiza monga pampu thupi.
