Ucwaningo lokuhlola lwepompo ye-china slurry kanye nesiqondiso sesikhathi esizayo sokuthuthukiswa
Nge-PIV , ubuchwepheshe be-LDV kanye nobuchwepheshe be-ultrasonic buvuthwa, abantu bangasebenzisa ngokunenzuzo lobu buchwepheshe obuthuthukisiwe ekuhlolweni kwenkambu yokugeleza ngaphandle kwenkambu yokugeleza kokuphazamiseka yezilinganiso zokunemba okuphezulu.
Obunye balobu buchwepheshe obuthuthukisiwe buye bacwaningwa kusetshenziswa inkambu yokugeleza kwephampu ye-china e-slurry eCanada, singasebenzisa lolu daba i-PIV (i-particle image velocimetry) eyenziwa ucwaningo lokuhlola, okuqukethwe kwayo okuyinhloko ukusatshalaliswa kwepompo lapho ukunqunywa kwenkambu ehlukene yokugeleza. ukugeleza nokuqhathanisa lapho isigaba esixubile kanye nesigaba esisodwa sokugeleza kwesigaba se-china slurry pump ukufana nokwehluka.
Inqubo yokuhlola:
Ukusebenzisa ukuminyana kanye ne-viscosity kawoyela ongahluziwe wamafutha amhlophe emboni afanayo njengendawo yokuhlola , namafutha amhlophe anokuminyana eduze kwe-GDX501 yobuhlalu be-polystyrene njengezinhlayiya zokulandelela .Ishidi lokukhanya eliqinile lisebenzisa i-10W yejeneretha ye-laser ye-neon kanye nesistimu yokubona ehambisanayo njengomphumela wokukhanya kwekhamera ye-PIV , kanye nokusetshenziswa kwevidiyo noma izindlela zezithombe ukuqopha izithombe ze-PIV.Ezimweni ezihlukene, ngokulandelana, ngaphansi kwezimo zokugeleza kwesigaba esisodwa kanye nezigaba ezimbili okuphakathi kwe-china slurry pump pump tube, i-valve , i-piston nezinye izingxenye zokurekhoda kwesithombe se-PIV nokuthatha izithombe, ukulungiselela ukuhlaziya nokucubungula okwengeziwe.
Imiphumela yokuhlola nokuhlaziya:
Njengoba isifundo se-deep-well fixed valve parts flow field sinemiphumela yocwaningo ehambisanayo, kanye nohlelo lokucutshungulwa kwezithombe lwe-gas-liquid lwezigaba ezimbili ze-PIV aluphelele, ngakho-ke lapha kugxilwe ekuhlaziyweni kwe-flow medium china slurry pump uma uhamba. ivalvu kanye nekholomu yesigaba esisodwa soketshezi izingxenye zaseCyprus zenkundla yokugeleza .
Ukunyakaza kwepompo ye-china slurry
Ezivivinyweni, ukunyakaza kwe-valve nokuphila kwe-china slurry pump abantu bayazi ukuthi akufani ncamashi, ngaphezu kokunyakaza kwayo komugqa okuqondile kwezemidlalo, okuhambisana nokunyakaza okubili okujikelezayo.Lapho ijubane lepiston elincane, ibhola elizungeza i-eksisi evundlile yokuzungezisa ngaphansi;Uma isivinini se-piston sisikhudlwana, ukuzungezisa kwebhola eduze kwe-eksisi eqondile nezimbobo ezivundlile emakhoneni angaphakathi aleyo sihlalo sembobo se-axis ephakathi nendawo yokuguquguquka .Isivinini se-engular sesivinini sokuzungezisa sokunyakaza kwe-plunger , lapho isivinini sokunyakaza kwe-plunger sikhulu , siba sikhulu isivinini esizungezayo se-angular yebhola .Indlela ekhethekile yokuzivocavoca ihlobene kakhulu nomthelela webhola kanye nebhola le-valve eliwuketshezi, isakhiwo sesihlalo se-valve sihlobene.I-china slurry futha i-valve iyi-valve yebhola , lapho uketshezi lugeleza luyizungeza engxenyeni engemuva yento eyenzeka kusukela kungqimba lomngcele , kuyilapho ikhiqiza injabulo ehlangene .Ngenxa yokulinganisa kwebhola , le njabulo yangemuva ezungeza ibhola eduze komjikelezo “wenkabazwe ” ukuhambisa ibhola le-valve ayihlali ikumugqa we-axis wembobo yesihlalo, kodwa ichezukela kude futhi isondele esihlalweni esisekhoneni lesihlalo. ukuzungezisa, okuyinto "revolution ” phenomenon.
Ngaphezu kwalokho , ngenxa yokungaqini kokugeleza koketshezi kanye nokuphambuka kwebhola eliwuketshezi okubangelwa ukunyakaza okuhlobene kwe-valve yebhola i-asymmetry yebhola izoba nomnyakazo othize wokuklwebheka, ngakho lokhu akuwona amandla asemaceleni asebenza phakathi nendawo ye-sphere, kodwa indiza evundlile kanye nokugqama okuthile , kukhona i-valve yebhola ezungeza endizeni evundlile , okungukuthi, ” ukuzungezisa ” ukwenzeka.Lezi ziphetho zitholakala endabeni yoketshezi olumsulwa .Lapho ukugeleza kwesigaba esixutshwe negesi-uketshezi , ngenxa yobukhona bamabhamuza , insimu yokugeleza iphazamisa kakhulu, futhi i-bubble yebhola inomthelela othile, ngalesi sikhathi ukunyakaza kwebhola kuyinkimbinkimbi kakhulu , ngaphezu kokunyakaza okujikelezayo , kanye nokushaywa okunobudlova phansi naphezulu.
Kuphethe ngokuthi iphampu ye-china slurry yenziwe ukubhekana nalokhu okulandelayo:
( 1 ) ibhola lingenye yezingxenye eziyinhloko zephampu yephampu ye-china , futhi egqoke izingxenye , ezinquma ukusebenza kahle kwepompo kanye nomjikelezo wokuhlola iphampu.Izincomo zokugeleza kwesigaba esixubile i-china slurry futha futha i-eccentric spherical valve valve , umgijimi omncane we-china slurry futha esebenzisa ibhola elidonsayo lemithombo edonsayo yesihlabathi ehlanganiswe nephampu yase-china e-slurry ivalwa kusetshenziswa ibhola lerabha elicijile.
( 2 ) endaweni ukuze kuqinisekiswe izimo eziphezulu ze-overcurrent , ukugeleza kwe-cross-section shape ye-valve dome kufanele kwenziwe lula ngangokunokwenzeka ukuze kuncishiswe ukumelana nokugeleza ngokweqile.
( 3 ) ukwakheka komklamo we-plunger , idizayini eqondiwe kufanele icatshangelwe noma indawo engezansi yomlomo wensimbi yokumunca yohlobo lwe plunger ukunciphisa ukumelana nokumunca.Ukuphuma kwe-plunger kuqinisekisa ukugeleza okuphezulu kwe-cross-section , kuyilapho indlela yokuphuma kwe-plunger iklanyelwe ukuhleleka ukuze kuncishiswe ukumelana nokugeleza kwe-plunger phezu kokuphumayo.
