Kev nkag siab ntawm lub hauv paus ntawm slurry twj tso kua mis

I. Lub twj tso kua mis slurry yog dab tsi? Nws yog tsim tshwj xeeb los thauj cov slurry uas muaj cov khoom siv: xws li ntxhia slurry, tailings, av nkos, tshauv residue, thee sludge, xuab zeb thiab gravel, roj av drilling av, thiab lwm yam. Cov yam ntxwv tseem ceeb: hnav- tiv taus, tiv thaiv- thaiv, muaj peev xwm tshem tawm impurities, thiab lub twj tso kua mis dej tsis tuaj yeem ua qhov no.
II. Cov qauv yooj yim (nco txog 6 cov ntsiab lus no txaus): Impeller: cov khoom tseem ceeb ua haujlwm, feem ntau yog hnav; Npog / Turbine vaj tse: sab hauv hauv ob sab phlu ntawm lub twj tso kua mis chamber, tiv thaiv lub hauv ntej thiab nram qab daim hlau; Guard phaj: tiv thaiv ob sab ntawm lub impeller, hnav- ib feem; Twj lub cev / Lub twj tso kua mis npog: lub plhaub sab nraud, lub taub hau, cov kabmob sib dhos: qhov kis tau tus mob; Sealing: tiv thaiv slurry to (packing seal / auxiliary impeller / mechanical seal).
III. Qhov tseem ceeb tshaj plaws: Cov khoom siv (cov neeg siv khoom nyiam tshaj plaws) Siab -chromium alloy (Cr26 / Cr27 / Cr28) yog qhov hnav tshaj plaws - tiv taus, tuaj yeem tiv taus cov khoom loj thiab muaj zog yaig: haum rau cov mining tailings, xuab zeb thiab gravel, roj av xuab zeb twj, tshauv residue; Roj hmab hauv ob sab phlu (natural rubber / neoprene): resistant rau cov khoom zoo, corrosion-resistant, pheej yig thiab siv tau: nplua slurry, desulfurization slurry, tsis muaj zog acid nruab nrab; Stainless hlau / duplex steel yog corrosion-resistant, siv nyob rau hauv chemical kev lag luam, acidic slurry.
IV. Cov kev ua haujlwm tseem ceeb (yuav tsum nkag siab): Tus nqi ntws Q: pes tsawg cubic meters ib teev (m³ / h) tuaj yeem nqus tau; Lub taub hau H: siab npaum li cas thiab deb npaum li cas nws tuaj yeem nqus tau; Ceev: qhov siab dua qhov ceev, qhov ntau dua qhov ntws thiab lub taub hau, tab sis qhov hnav sai dua; Fais fab: qhov loj ntawm lub cev muaj zog; Kev ua tau zoo: tib qhov ntws thiab lub taub hau, lub zog ntau dua -kev ua tau zoo dua; Cavitation margin: txiav txim siab seb nws puas tuaj yeem nqus dej thiab seb nws puas yuav khoob.
V. Hom hom: Kab rov tav slurry twj (ZJ, AH hom) yog siv ntau tshaj; Vertical submersible twj rau tailings (SP, ZJL) yog siv nyob rau hauv cov pas dej ua ke, tsis muaj hauv qab li qub, tsis ntshai dej nyab; Submersible slurry twj rau dej dredging, xuab zeb twj, ntses pas dej sludge thiab xuab zeb gravel; Slurry twj tso kua mis loj pebbles, coarse xuab zeb, hiav txwv xuab zeb, roj av xuab zeb twj, siv rau drilling khoom tswj systems, thauj slurry thiab tshem cov xuab zeb.
VI. Ua hauj lwm hauv paus ntsiab lus (ib kab lus): Lub cev muaj zog tsav lub impeller kom tig ntawm kev kub ceev → generates centrifugal quab yuam → pov lub slurry tawm → cov ntaub ntawv suction quab yuam kom tsis tu ncua twj slurry.
VII. Kev lag luam muaj feem xyuam (nco lawv thiab koj tuaj yeem tau txais cov xaj): Mining: mining processing, tailings thauj; Hwj chim: fais fab nroj tsuag tshauv tshem tawm, desulfurization slurry; Coal: thee ntxuav cog, thee sludge, hnyav nruab nrab metallurgy: steel slag, liab av nkos, sludge; Dredging: dej dredging, xuab zeb siv, puam puv; Petroleum: drilling slurry, khoom tswj system; Municipal: pawg tsav slurry, ntaub thaiv npog tunneling tawm.
VIII. Feem ntau ua txhaum (cov neeg siv khoom yuav tsum nug): Tsis txaus txaus, tsis muaj siab: cua nkag, hauv qab valve leaks, impeller thaiv; Slurry to: foob tawg, siab npog xoob, hnav yog ceev; Cov khoom tsis sib xws, cov ntsiab lus khoom siab dhau lawm; Kev co yog qhov loj: kev sib dhos yog qhov tsis zoo, cov kabmob tawg, impeller tsis sib npaug; Bearing overheats: tsis muaj roj, kev teeb tsa tawm -center, overload.
IX. Qhov sib txawv ntawm cov twj tso kua dej: cov twj tso kua dej: ntshai ntawm cov khoom, ib qho kev sib tsoo yuav tawg; Slurry twj: tshwj xeeb resistant rau hnav, dav ntws channel, ruaj, tsis ntshai sludge.
X. Kev txwv kev siv (tseem ceeb heev): Tsis txhob tso cai rau kev sib hloov → foob thiab impeller tsis tuaj yeem raug hlawv ncaj qha; Ntshuam tsis tuaj yeem thaiv; Tsis txhob tso cua nkag → tsis txaus txaus tsis tuaj yeem ua tiav; Tsis txhob khiav qis qis rau lub sijhawm ntev → overheating, vibration; Cov khoom loj dhau lawm, tsis txhob thawb lub zog → thaiv lub twj tso kua mis, ua rau lub impeller puas.
