Lapho isevisi entsha iphampu yecala lokuhlukanisa elivundlile isebenza kabi, inqubo enhle yokuxazulula inkinga ingasiza ekuqedeni amathuba amaningi, okuhlanganisa izinkinga ngepompo, uketshezi olumpontshwa (ukumpompa uketshezi), noma amapayipi, okokufakwayo, neziqukathi (uhlelo) oluxhunywe kwiphampu. Uchwepheshe onolwazi onokuqonda okuyisisekelo kwamajika epompo nemingcele yokusebenza anganciphisa ngokushesha amathuba, ikakhulukazi lawo ahlobene namaphampu.

Evundlile Hlukanisa Ikesi Pumps

Ukuze unqume ukuthi ingabe inkinga ikupompo, kala inani lekhanda lephampu eliguqukayo (i-TDH), ukugeleza, nokusebenza kahle futhi ukuqhathanise nejika lephampu. I-TDH ingumehluko phakathi kokuphuma kwephampu nezingcindezi zokumunca, eziguqulelwa ezinyaweni noma amamitha ekhanda (Qaphela: Uma kunekhanda elincane noma lingekho noma ukugeleza ekuqaleni, vala iphampu ngokushesha futhi uqinisekise ukuthi kunoketshezi olwanele epompo, okungukuthi, igumbi lepompo ligcwele uketshezi. Uma indawo yokusebenza ikujika lepompo, iphampu isebenza kahle. Ngakho-ke, inkinga ikusistimu noma izici zemidiya zokumpompa. Uma indawo yokusebenza ingaphansi kwejika lepompo, inkinga ingase ibe ngepompo, isistimu, noma ukumpompa (okuhlanganisa izici zemidiya). Kunoma yikuphi ukugeleza okuqondile, kunekhanda elihambisanayo. Idizayini ye-impeller inquma ukugeleza okuqondile lapho iphampu isebenza kahle kakhulu - indawo engcono kakhulu yokusebenza kahle (BEP). Izinkinga eziningi zephampu nezinye izinkinga zesistimu zibangela ukuthi iphampu isebenze endaweni engaphansi kwejika layo elivamile lepompo. Uchwepheshe oqonda lobu budlelwano angakala amapharamitha wokusebenza kwephampu futhi ahlukanise inkinga empompini, ekupompeni, noma kusistimu.

I-Pumped Media Properties

Izimo zemvelo ezifana nezinga lokushisa zishintsha i-viscosity yemidiya empontshiwe, engashintsha ikhanda lepompo, ukugeleza, nokusebenza kahle. Amafutha amaminerali ayisibonelo esihle soketshezi olushintsha i-viscosity ngokushintshashintsha kwezinga lokushisa. Uma imidiya epompowe iyi-asidi eqinile noma isisekelo, ukuhlanjululwa kushintsha amandla adonsela phansi athile, okuthinta ijika lamandla. Ukuze unqume ukuthi ingabe inkinga ikwimidiya emponliwe, izici zayo zidinga ukuqinisekiswa. Ukuhlola imidiya empontshelwe ukubona i-viscosity, amandla adonsela phansi athile, nezinga lokushisa kulula futhi akubizi. Amathebula okuguqulwa ajwayelekile namafomula ahlinzekwe yi-Hydraulic Society nezinye izinhlangano angasetshenziswa ukuze kutholwe ukuthi ingabe imidiya emponliwe inomthelela omubi ekusebenzeni kwephampu.

System

Uma izakhiwo eziwuketshezi sezikhishiwe njengethonya, inkinga ingokwehlukana okuvundlile iphampu yecala noma uhlelo. Futhi, uma iphampu isebenza ejikeni lepompo, isebenza kahle. Kulokhu, inkinga kufanele ibe nohlelo iphampu exhunywe kulo. Kunamathuba amathathu:

1. Kungakhathaliseki ukuthi ukugeleza kuphansi kakhulu, ngakho-ke ikhanda liphakeme kakhulu

2. Kungakhathaliseki ukuthi ikhanda liphansi kakhulu, okubonisa ukuthi ukugeleza kuphezulu kakhulu

Uma ucabangela ikhanda nokugeleza, khumbula ukuthi iphampu isebenza kahle ejikeni layo. Ngakho-ke, uma enye iphansi kakhulu, enye kufanele ibe phezulu kakhulu.

3. Okunye okungenzeka ukuthi ipompo engalungile isetshenziswa ohlelweni. Ngokuklama okungalungile noma ngokufaka okungalungile kwezingxenye, okuhlanganisa ukuklama/ukufaka i-impeller engalungile.

Ukugeleza Okuphansi Kakhulu (Ikhanda Eliphakeme Kakhulu) - Ukugeleza okuphansi kakhulu ngokuvamile kubonisa ukuvinjelwa emugqeni. Uma ukuvinjelwa (ukumelana) kukumugqa wokuncela, i-cavitation kungenzeka. Uma kungenjalo, ukuvinjelwa kungase kube kulayini wokukhipha. Okunye okungenzeka ukuthi ikhanda elimile lokumunca liphansi kakhulu noma ikhanda elimile lokukhipha liphezulu kakhulu. Isibonelo, ithange lokudonsa/ithangi lingase libe neswishi yokuntanta ehlulekayo ukuvala iphampu lapho izinga lehla ngaphansi kwephoyinti elimisiwe. Ngokufanayo, ukushintshwa kwezinga eliphezulu ethangini lokukhipha amanzi kungase kube nephutha.

Ikhanda eliphansi (ukugeleza okuningi) - Ikhanda eliphansi lisho ukugeleza okuningi, futhi cishe aliyi lapho kufanele. Ukuvuza ohlelweni kungaba ngaphakathi noma ngaphandle. I-diverter valve evumela ukugeleza okuningi ukuthi idlule, noma i-valve yokuhlola ehlulekile ebangela ukugeleza ukuze ijikeleze emuva ngepompo ehambisanayo, ingabangela ukugeleza okukhulu kanye nekhanda elincane kakhulu. Ohlelweni lwamanzi kamasipala agqitshiwe, ukuvuza okukhulu noma ukuphuka kwentambo kungabangela ukugeleza okukhulu, okungabangela ikhanda eliphansi (ukucindezela komugqa ophansi).

Yini engaba iphutha?

Lapho iphampu evulekile yehluleka ukusebenza ejikeni, futhi ezinye izimbangela zikhishwe ngaphandle, izimbangela ezingenzeka kakhulu yilezi:

- I-impeller eyonakele

- I-impeller evaliwe 

- Ivolumu evaliwe

- Indandatho yokugqoka ngokweqile noma imvume ye-impeller

Ezinye izimbangela zingase zihlotshaniswe nesivinini sepompo yokuhlukanisa icala elivundlile - i-shaft spinning ku-impeller noma isivinini somshayeli esingalungile. Nakuba isivinini somshayeli singaqinisekiswa ngaphandle, ukuphenya ezinye izimbangela kudinga ukuvula iphampu.
