Izindaba - Ukuhlaziywa Kwezinto Eziyinhloko Ezithinta Ukusebenza Kwamaphampu Ase-Centrifugal

Amaphampu we-Centrifugalzisetshenziswa kabanzi ezimbonini ezahlukene njengezinto ezibalulekile zokuthutha uketshezi. Ukusebenza kahle kwazo kuthinta ngqo kokubili ukusetshenziswa kwamandla kanye nokuthembeka kwemishini. Kodwa-ke, ekusebenzeni, amaphampu angama-centrifugal avame ukuhluleka ukufinyelela ukusebenza kahle kwawo okuphezulu kwethiyori. Lokhu kushoda kubangelwa inhlanganisela yemikhawulo yedizayini, ukuhluka kokusebenza, izindaba zokunakekelwa, kanye nezici zangaphandle zemvelo.

Ukuqonda I-Centrifugal Pump Efficiency

Ukuze uhlaziye ngempumelelo izinto ezithinta ukusebenza kahle kwephampu, kubalulekile ukuthi uqale uqonde ukwakheka kwayo. Ukusebenza kahle okuphelele kwe-aiphampu yomlilo ye-centrifugalngokuvamile kunqunywa izingxenye ezintathu ezibalulekile:

Ukusebenza Kwe-Hydraulic– Imele ukulahleka kwamandla ngenxa ye-fluid dynamics ngaphakathi kwepompo.

Ukuphumelela Kwemishini- Kubhekiselwa ekulahlekelweni okuvela ekungqubuzaneni nokunyakaza komshini.

Ukusebenza kahle kweVolumetric- I-akhawunti yokulahlekelwa okubangelwa ukuvuza kwangaphakathi koketshezi.

Ukusebenzisana phakathi kwalezi zingxenye kuchaza ukusebenza kahle okuphelele kwephampu.

Izinto Ezibalulekile Ezithonya Ukusebenza Kwephampu Ye-Centrifugal

1. I-Hydraulic Design Factors

Idizayini ye-hydraulic ithonya kakhulu indlela uketshezi oluhamba kahle ngayo epompo:

I-Impeller Design Njengengxenye eyinhloko, i-geometry ye-impeller-okuhlanganisa ububanzi, inombolo ye-blade, ama-engeli okungenisa/okuphumayo, kanye nokugoba—kuthinta ngokuqondile izici zokugeleza nokusebenza kahle kokuguqulwa kwamandla.

I-Volute Design I-volute iqoqa uketshezi oluphuma ku-impeller futhi iguqule amandla e-kinetic abe amandla okucindezela. Idizayini engalungile, ikakhulukazi ama-engeli okusabalalisa ngokweqile, ingabangela ama-eddies nokugeleza kwesibili, okwandisa ukulahlekelwa kwamanzi.

Ukucaciswa kwe-Seal Design Seal kunomthelela kukho kokubili ukuvuza nokulahlekelwa kokungqubuzana. Ukususwa ngokweqile kuholela ekuvuzeni, kuyilapho ukucaciswa okuncane kungakhuphula ukungqubuzana nokuguga.

2. Izimo zokusebenza

Ukuchezuka ezicacisweni zedizayini kungathinta kakhulu ukusebenza:

I-Off-Design Operation Pumps yakhelwe ukusebenza endaweni Engcono Kakhulu Efficiency Point (BEP). Ukusebenza kude kakhulu naleli phuzu kubangela ukulahleka kwe-hydraulic anda kanye nokusebenza kahle okuncishisiwe.

I-Cavitation Lapho ingcindezi ohlangothini lokumunca yehla ngaphansi komfutho womhwamuko woketshezi, amabhamuza omhwamuza akha futhi awele ngaphakathi kwe-impeller, izingxenye ezilimazayo futhi anciphise ukusebenza kahle.

3. I-Mechanical Loss Factors

Ukulahleka kwemishini kusuka ekungqubuzaneni kwangaphakathi nokuguga kwezingxenye:

I-Bearing and Seal Friction Friction at seal and bearings inegalelo elikhulu ekulahlekeni kwamandla. Ukusebenzisa izinto ezisebenza kahle kakhulu, ezingqubuzana kancane kunganciphisa lokhu.

Ukulinganisa Ukulahleka Kwedivayisi Amaphampu e-multistage ngokuvamile asebenzisa amadivaysi okulinganisa ukuze alwe ne-axial thrust. Idizayini engafanele noma ukugqokwa kungangenisa ukulahleka kwamandla okwengeziwe.

Ukuvuza Kwezimpawu Ngokuhamba kwesikhathi, izimpawu zingase zonakale, okuholela ekuvuzeni koketshezi kanye nokuncipha kokusebenza kahle kwevolumu.

4. Izinkinga Ezihlobene Nesondlo

Ukunakekelwa okuqhubekayo kubalulekile ekuqhubekiseni ukusebenza:

I-Impeller ne-Volute Wear Ukusebenza okuqhubekayo kuholela ekugubheni nasekugugulekeni kwendawo yangaphakathi, okwandisa ukumelana nokusetshenziswa kwamanzi kanye nokulahlekelwa.

Ukwenyuka Kokumelana Nesistimu Ukungaguquguquki noma ukuvala ngaphakathi kwamapayipi kwandisa ukumelana nokugeleza, kunciphisa ukusebenza kahle kwepompo jikelele.

Ukungalungi kahle kwe-Shaft Ukuqondanisa okungalungile phakathi kwe-pump shaft nomshayeli kungabangela ukudlidliza, kuphakamise ukulahlekelwa kwemishini, futhi kunciphise impilo yesevisi.

5. Izici Zemvelo

Izimo zangaphandle ziphinde zibe nomthelela ekusebenzeni kwephampu:

I-Fluid Viscosity I-viscosity ephezulu inyusa ukumelana nokugeleza, inciphisa ukusebenza kahle.

I-Solids Content Fluids enama-solids amisiwe abangela ukuguga nokugeleza okukhulayo, okuholela ekwehleni kokusebenza kahle.

I-Ambient Temperature Temperature ithinta kokubili izakhiwo zoketshezi kanye nokusebenza kwamasistimu okugcoba, okunomthelela ekusebenzeni kahle kukonke.

Amasu Okuthuthukisa I-Centrifugal Pump Efficiency

Ukuze uthuthukise ukusebenza kahle nokuthembeka kwamaphampu amaphakathi, cabanga ngalezi zindlela ezilandelayo:

Idizayini Ethuthukisiwe Sebenzisa i-computational fluid dynamics (CFD) ukuze ulingise amaphethini okugeleza kwangaphakathi futhi uthuthukise i-impeller futhi uvotele ukulahlekelwa okuncane kwe-hydraulic.

Ukukhethwa Nokulawula Okufanelekile Kwephampu Qinisekisa ukuthi amaphampu asebenza eduze kwendawo yawo yokuklama. Sebenzisa amadrayivu okuguquguqukayo (ama-VFD) ukuze ulungise isivinini ngokususelwe esidingweni, futhi ucabange ukusebenzisa amaphampu amaningi ngokuhambisana ukuze ufanise ukuguquguquka komthwalo ngendlela efanele.

Ukunakekela Okuvamile Sebenzisa uhlelo lokulungisa olusebenzayo. Hlanza indawo yangaphakathi, shintsha izingxenye ezigugile, futhi uqaphe izimo usebenzisa amasu anjengokuhlaziya ukudlidliza nokulandelela izinga lokushisa.

Zivumelanisa Nezimo Zendawo Khetha izinhlobo zephampu ezihambisana nezakhiwo zoketshezi oluphathwayo. Lapho kungenzeka khona, phatha izimo ze-ambient ukuze unciphise umthelela wazo ekusebenzeni.

Isiphetho

Ukusebenza kahle kwamaphampu e-centrifugal kuthonywa uhla olubanzi lwezinto ezixhumene. Ngokubhekana nomklamo we-hydraulic, ukuqondanisa imingcele yokusebenza, ukugcina izingxenye zemishini, nokuphatha imithelela yemvelo, ukuthuthuka okukhulu ekusebenzeni kwepompo nokongiwa kwamandla kungafinyelelwa. Indlela ebanzi, esebenzayo ibalulekile ekwandiseni ukusebenza kahle kwesikhathi eside nokuthembeka kwezinhlelo zamaphampu ezimaphakathi.
