Xa kusenziwa inkonzo entsha impompo yecala lokwahlulwa elithe tyaba iqhuba kakubi, inkqubo efanelekileyo yokusombulula ingxaki inokunceda ekupheliseni inani lamathuba anokwenzeka, kubandakanywa iingxaki ngempompo, ulwelo olumpontshwayo (ukumpompa ulwelo), okanye imibhobho, izifakelo, kunye nezikhongozeli (inkqubo) edityaniswe nempompo. Umchwephesha onamava kunye nokuqonda okusisiseko kwee-curves zepompo kunye neeparitha zokusebenza zinokunciphisa ngokukhawuleza amathuba, ngakumbi ezo zihambelana neepompo.

Horizontal Ityala lokwahlula Iipompo

Ukufumanisa ukuba ingxaki ikwimpompo, linganisa intloko yempompo epheleleyo (TDH), ukuhamba, kunye nokusebenza kakuhle kwaye uthelekise kunye negophe lempompo. I-TDH ngumahluko phakathi kokukhutshwa kwempompo kunye noxinzelelo lokufunxa, oluguqulelwe kwiinyawo okanye kwiimitha zentloko (Qaphela: Ukuba kukho intloko encinci okanye akukho nto okanye ukuhamba kwayo ekuqaleni, vala impompo ngokukhawuleza kwaye uqinisekise ukuba kukho ulwelo olwaneleyo kwimpompo; oko kukuthi, igumbi lokumpompa lizele lulwelo Ukomisa impompo kunokonakalisa amatywina. Ukuba indawo yokusebenza ikwigophe lempompo, impompo isebenza ngokufanelekileyo. Ngoko ke, ingxaki yinkqubo okanye ukupompa iimpawu zemidiya. Ukuba indawo yokusebenza ingaphantsi kwe-curve yepompo, ingxaki ingaba nempompo, inkqubo, okanye ukupompa (kubandakanywa neempawu zeendaba). Kuyo nakuphi na ukuhamba okuthe ngqo, kukho intloko ehambelanayo. Uyilo lwe-impeller lumisela ukuhamba okuthe ngqo apho umpompo usebenza kakhulu - eyona ndawo isebenzayo (BEP). Iingxaki ezininzi zempompo kunye nezinye iingxaki zenkqubo zibangela ukuba impompo isebenze kwindawo engaphantsi kwegophe layo eliqhelekileyo lepompo. Umchwephesha oqondayo olu budlelwane unokulinganisa iiparitha zokusebenza zempompo kwaye ahlukanise ingxaki kwimpompo, ukupompa, okanye inkqubo.

IiPropathi zeMedia eziPumped

Iimeko zokusingqongileyo ezifana nokutshintsha kweqondo lokushisa kwe-viscosity ye-media mediated, enokutshintsha intloko yempompo, ukuhamba kunye nokusebenza kakuhle. Ioyile yamaminerali ngumzekelo omhle wolwelo olutshintsha i-viscosity ngokuguquguquka kobushushu. Xa imidiya epompelweyo i-asidi eyomeleleyo okanye isiseko, i-dilution iguqula ubunzima bayo obuthile, obuchaphazela ijika lamandla. Ukugqiba ukuba ingxaki ifakwe kwi-media media, iipropati zayo kufuneka ziqinisekiswe. Ukuvavanya imidiya epompelweyo ye-viscosity, ubunzima obuthile, kunye nobushushu bukulungele kwaye akubizi. Iitheyibhile zokuguqulwa okusemgangathweni kunye neefomula ezibonelelwa nguMbutho we-Hydraulic kunye neminye imibutho ingasetyenziselwa ukugqiba ukuba i-media media pumped ichaphazela kakubi ukusebenza kompompo.

isixokelelwano

Emva kokuba iimpawu ze-fluid zikhutshwe njengempembelelo, ingxaki kukuhlukana okuthe tye impompo yetyala okanye inkqubo. Kwakhona, ukuba impompo isebenza kwigophe lempompo, isebenza ngokufanelekileyo. Kule meko, ingxaki kufuneka ibe nenkqubo ipompo exhunywe kuyo. Kukho izinto ezintathu ezinokwenzeka:

1. Ingaba ukuhamba kuphantsi kakhulu, ngoko intloko iphezulu kakhulu

2. Okanye intloko iphantsi kakhulu, ebonisa ukuba ukuhamba kuphezulu kakhulu

Xa uqwalasela intloko kunye nokuhamba, khumbula ukuba impompo isebenza ngokuchanekileyo kwijika layo. Ngoko ke, ukuba enye iphantsi kakhulu, enye kufuneka ibe phezulu kakhulu.

3. Enye into enokwenzeka kukuba ipompo engafanelekanga isetyenziswa kwisicelo. Nokuba ngoyilo olubi okanye ngofakelo olungachanekanga lwamacandelo, kuquka ukuyila/ukufaka i-impeller engalunganga.

Ukuhamba okuphantsi kakhulu (iNtloko ephezulu kakhulu) - Ukuhamba okuphantsi kakhulu ngokuqhelekileyo kubonisa isithintelo kumgca. Ukuba ukuthintela (ukuchasana) kumgca wokufunxa, i-cavitation ingenzeka. Ngaphandle koko, isithintelo sinokuba kumgca wokukhupha. Ezinye izinto ezinokwenzeka kukuba intloko emileyo yokufunxa iphantsi kakhulu okanye i-dicharge static intloko iphezulu kakhulu. Umzekelo, itanki yokufunxa / itanki inokuba neswitshi edadayo engakwaziyo ukuvala impompo xa inqanaba lehla ngaphantsi kwendawo ebekiweyo. Ngokufanayo, ukutshintshela kwinqanaba eliphezulu kwitanki yokukhupha / itanki ingaba nephutha.

Intloko ephantsi (ukuhamba kakhulu) - Intloko ephantsi ithetha ukuhamba kakhulu, kwaye mhlawumbi ingayi apho ifanele. Ukuvuza kwinkqubo kunokuba ngaphakathi okanye ngaphandle. I-valve ye-diverter evumela ukuhamba kakhulu ukuba idlule, okanye i-valve yokutshekisha engaphumelelanga eyenza ukuba ukuhamba kujikeleze umva ngepompo ehambelanayo, kunokubangela ukuhamba kakhulu kunye nentloko encinci. Kwinkqubo yamanzi kamasipala engcwatyiweyo, ukuvuza okukhulu okanye ukugqabhuka komgca kunokubangela ukuhamba kakhulu, okunokubangela intloko ephantsi (uxinzelelo lomgca ophantsi).

Inokuba yintoni ingxaki?

Xa impompo evulekileyo isilela ukusebenza kwigophe, kwaye ezinye izizathu zikhutshiwe, ezona zizathu zinokwenzeka zezi:

- Impeller eyonakeleyo

- impeller evaliweyo 

-Ivolonti evaliweyo

-Iringi yokunxiba ngokugqithisileyo okanye i-impeller clearance

Ezinye izizathu zinokunxulunyaniswa nesantya sempompo yecala lokuqhekeka okuthe tye - i-shaft spinning kwi-impeller okanye isantya somqhubi esingalunganga. Nangona isantya somqhubi sinokuqinisekiswa ngaphandle, ukuphanda ezinye izizathu kufuna ukuvula umpompo.
