Lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv hauv Slurry Pump Durability
Hauv kev lag luam abrasive xws li mining, mineral processing, thiab thee npaj, cov qauv tsim ntawm lub twj slurry tsuas yog ib nrab ntawm kev sib ntaus sib tua. Lwm qhov, sib npaug ib nrab tseem ceeb, yog cov khoom siv ntawm nws cov wetted qhov chaw. Kev xaiv cov khoom tsim nyog yog ib qho tseem ceeb tshaj plaws hauv kev txiav txim siab lub twj tso kua mis lub neej, lub sijhawm tu, thiab tag nrho cov nqi ntawm cov tswv cuab. Lub twj tso kua mis uas zoo kawg nkaus rau daim ntawv thov tseem tuaj yeem ua tsis tiav hauv ib lub lis piam yog tias nws cov ntaub ntawv tsis tuaj yeem tiv taus qhov tshwj xeeb ntawm slurry. Kev nkag siab txog qhov sib txawv ntawm cov khoom siv no yog qhov tseem ceeb rau txhua tus neeg ua lag luam loj lossis tus muag khoom.
Qhov kev xaiv ntau tshaj plaws rau kev tuav cov khoom ntxhib, ntse, thiab muaj zog abrasive yog siab -Chrome Alloy. Cov no yog cov hlau-raws li alloys uas muaj feem pua ntawm cov chromium (feem ntau 25-28%), uas tsim cov chromium carbides nyuaj heev hauv cov hlau microstructure. Qhov hardness no, feem ntau tshaj 650 ntawm Brinell nplai, tso cai rau cov khoom los tiv thaiv kev txiav thiab sib tsoo ntawm kev txhoj puab heev slurries. Qhov no yog vim li cas high-chrome alloy yog lub neej ntawd specification rau lub luag hauj lwm hnyav slurry twj siv nyob rau hauv thawj sib tsoo zeb paug los yog xuab zeb thiab gravel ua hauj lwm. Lub hardness muab superior tiv thaiv zawv zawg abrasion, ua rau nws zoo tagnrho armor rau slurry twj rau mining.
Txawm li cas los xij, hardness tsis yog ib qho kev daws teeb meem zoo tshaj plaws. Rau cov ntawv thov uas muaj cov khoom zoo, muaj kev cuam tshuam siab, lossis qee yam tshuaj muaj pes tsawg leeg, elastomeric liner zoo li ntuj Rubber feem ntau zoo dua. Tsis txhob tiv thaiv lub zog abrasive nrog hardness, roj hmab absorbs lub zog kinetic ntawm cov khoom cuam tshuam thiab tso tawm, txo qis hnav. Nws ua tau zoo thaum tuav slurries nrog cov khoom sib npaug mus txog qhov loj me. Tsis tas li ntawd, roj hmab muaj kev tiv thaiv zoo rau qee yam corrosive. Rau cov acidic lossis alkaline ib puag ncig uas cov hlau yuav nrawm nrawm, cov khoom siv zoo li Ceramics lossis tshwj xeeb macromolecule alloys muab kev tiv thaiv qhov kawg, muab kev tiv thaiv ob qho tib si rau tshuaj tua kab thiab puas, txawm tias tus nqi pib ntau dua.
Thaum kawg, xaiv cov khoom tsim nyog yog qhov kev txiav txim siab uas yuav tsum muaj kev nkag siab tob txog cov slurry cov khoom -xws li particle loj, cov duab, hardness, thiab tshuaj pleev ib ce. Kev koom tes nrog cov chaw tsim khoom paub txog uas tuaj yeem muab cov kws tshaj lij kev taw qhia yog qhov tseem ceeb. Qhov kev xaiv zoo ua kom ntseeg tau tias lub twj tso kua mis kab rov tav slurry yuav xa lub neej ua haujlwm ntev, ua kom lub sijhawm ua haujlwm ntev thiab muaj txiaj ntsig zoo.
