Vim li cas cavitation tshwm sim hauv ntau theem centrifugal twj?

Thaum siv ntau theem centrifugal twj, cavitation ib txwm tshwm sim. Qhov no yog vim li cas? Cov chaw tsim khoom ntawm ntau theem centrifugal twj nyob ntawm no los tham txog qhov teeb meem no.
Kev tshawb fawb txog qhov cuam tshuam ntawm gasification siab qhia tau hais tias thaum gasification siab nce, cavitation puas thawj zaug nce thiab tom qab ntawd txo. Raws li gasification siab nce, tus naj npawb ntawm tsis ruaj tsis khov npuas nuclei tsim nyob rau hauv cov kua kuj nce, ua rau ib tug ntau ntawm cov npuas ruptures, ib qho kev nce nyob rau hauv shock yoj siv, thiab ib tug nce nyob rau hauv cavitation tus nqi. Tab sis yog hais tias lub gasification siab tseem nce ntxiv, ua rau cov npuas kom ncav cuag ib qho kev txwv tshwj xeeb, pawg npuas tsim ib qho "txheej sib nrug" cov nyhuv, tiv thaiv kev poob siab los ntawm kev mus ncig thiab ua rau nws lub zog tsis muaj zog, thiab qhov kev puas tsuaj ntawm cavitation yuav maj mam. txo.
Thaum lwm yam tseem ceeb tsis hloov pauv, txo qhov nro ntawm cov kua dej tuaj yeem txo cov cavitation puas, vim hais tias raws li qhov nro ntawm cov kua dej txo, qhov kev siv ntawm qhov kev poob siab yoj tsim los ntawm npuas vau tsis muaj zog, thiab tus nqi cavitation txo.
Kev cuam tshuam ntawm qhov kub thiab txias ntawm lub cev ntawm cov roj erosion, xws li gasification siab, roj solubility, nto nro, thiab lwm yam, yuav cuam tshuam loj heev los ntawm kev hloov pauv kub hauv cov kua. Los ntawm qhov no, nws tuaj yeem pom tau tias cov txheej txheem ntawm qhov ntsuas kub ntawm qhov cavitation yog qhov nyuaj thiab yuav tsum tau txiav txim raws li qhov xwm txheej tiag tiag.
Noj AISI304 cov khoom impeller ua piv txwv, cavitation tuaj yeem ua rau kev ua haujlwm tawv thiab hloov pauv ntawm cov khoom siv impeller, inducing martensitic steel. Qhov kev hloov no yuav nyob rau hauv lem tiv thaiv ntxiv cavitation ntawm cov khoom. Lub zog ntawm kev ua hauj lwm hardening thiab theem transformation induced martensitic steel rau cavitation mas yog nyob ntawm hardness ntawm impeller khoom.
Nyob rau hauv qhov tseeb siv ntau theem centrifugal twj, vim tsis tshua muaj kev khiav hauj lwm tej yam kev mob, lub inlet txaus tus nqi thiab siab ntawm lub twj tso kua mis hloov tas li. Yog li ntawd, feem ntau muaj qhov sib txawv tseem ceeb ntawm qhov kev ua haujlwm tiag tiag ntawm lub twj tso kua mis centrifugal thiab cov kev sim thiab tsim kev ua haujlwm, thiab qhov ua tau ntawm cavitation yuav ntau dua li qhov kev xav tau ntawm kev sim.
