Cov kev ua haujlwm ntawm cov xuab zeb-blasting dav hlau muaj feem cuam tshuam rau kev ua haujlwm ntawm lub dav hlau, yog li kev tshawb fawb tam sim no ntawm kev txo qis hnav thiab txhim kho lub neej kev pab cuam feem ntau tsom rau kev xaiv cov khoom siv thiab cov yam ntxwv ntawm lub nozzle.

Rau txoj kev kawm ntawm sandblasting dav hlau nozzle cov ntaub ntawv, ib txwm txoj kev yog los txhim kho lub hardness ntawm cov khoom, xws li nto ntxiv dag zog rau technology, los yog txheej txheej ntawm hnav-resistant khoom nyob rau saum npoo los txhim kho nws hnav tsis kam; los yog txhim kho qhov ua tiav ntawm cov phab ntsa sab hauv thaum ua thiab tsim khoom kom ua tiav cov txiaj ntsig ntawm kev txo qis hnav. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv tshiab kuj tseem siv tas li hauv kev tsim cov nozzle, xws li kev siv cov khoom siv carbide siab heev los ua cov nozzles, tab sis cov ntaub ntawv ntom ntom tsis txawv ntau ntawm cov cemented carbide, thiab lub neej yog kaum ob zaug. siab dua.

Nyob rau hauv kev pom ntawm lub xeev siab ntawm lub ceramic nozzle ntawm qhov tawm thiab nkag, lub symmetrical laminated ceramic nozzle tau tsim. Vim tias muaj qhov seem ntawm cov kev ntxhov siab nyob hauv cov khoom, cov nplej tau ua kom zoo dua qub, qhov hardness thiab tawg toughness ntawm cov khoom saum npoo tau txhim kho, thiab kev yaig-hnav tsis kam ntawm laminated ceramic nozzle tau zoo heev. Los ntawm kev tswj cov kev faib tawm ntawm cov khoom kom ua tiav qhov tsim nyog gradient hloov ntawm nws cov khoom siv kho tshuab, qhov seem compressive stress generated thaum lub sij hawm npaj cov khoom yog nkag mus rau hauv lub nozzle inlet los txhim kho lub mechanical zog ntawm lub nozzle inlet. Vim tias kev txhim kho ntawm lub xeev kev ntxhov siab thiab cov khoom siv ntawm cov gradient ceramic nozzle, qhov kev yaig tsis kam ntawm cov gradient ceramic nozzle tau zoo dua qub dua li ntawm cov tsis-gradient ceramic nozzle.

Cov duab thiab geometric tsis ntawm lub nozzle ntws channel yog lub ntsiab yam tseem ceeb uas cuam tshuam rau lub dav hlau qauv thiab dynamic yam ntxwv. Thaum lub siab ua hauj lwm, ntws tus nqi thiab lwm yam tsis tau tsau, hloov lub puab puab thiab geometric tsis nyob rau hauv lub nozzle yog lub ntsiab txhais tau tias kom optimize lub nozzle qauv, nce cov xuab zeb ceev thiab txhim kho lub dav hlau nyhuv.

Kev xaus thiab kev nkag siab

Cov khoom siv nozzle, cov qauv tsim, sab hauv phab ntsa roughness, dav hlau siab, xuab zeb concentration, hardness, particle loj thiab cov duab tag nrho muaj cov nyhuv ntawm nozzle hnav. Txhim kho cov khoom hardness ntawm lub nozzle, kev txhim kho cov qauv qauv tsim ntawm lub puab ntws channel, kev txhim kho qhov tiav ntawm lub puab nto, thiab xaiv qhov tsim nyog ua hauj lwm tsis ntawm lub dav hlau thiab xuab zeb particle nyob rau hauv tej yam kev mob ntawm ua tau raws li qhov yuav tsum tau ua hauj lwm yuav txo tau. nozzle hnav thiab txuas nws lub neej kev pab cuam.

Kev txhim kho thiab xaiv cov khoom siv tshiab hnav-tiv taus, kev ua kom zoo thiab tsim ntawm nozzle sab hauv ntws channel qauv duab los ntawm kev sim thiab lub computer simulation, thiab kev tsim kho tshiab nozzle sab hauv qhov txheej txheem thev naus laus zis los txhim kho qhov ua tiav ntawm nws cov phab ntsa sab hauv yog lub hom phiaj ntawm yav tom ntej kev tshawb fawb ntawm hydraulic sandblasting dav hlau nozzles.
