Qhov tseem ceeb tshaj plaws uas txiav txim siab li cas amechanical foobua hauj lwm nyob ntawm seb lub rotating thiab nyob ruaj ruaj lub ntsej muag.Ntsej muag ntsej muags yog lapped li tiaj nws yog tsis yooj yim sua rau ib tug kua los yog gas ntws los ntawm lawv. Qhov no tso cai rau tus ncej tig, thaum lub foob raug tswj xyuas mechanically. Dab tsi txiav txim siab lub sijhawm lub foob yuav kav ntev li cas yog xaiv cov khoom foob raug cai ua ke rau daim ntawv thov. Lub ntsej muag tawv tawv rau kev pabcuam abrasive, Carbon Vs. Ceramic rau dej yooj yim (los yog tiv thaiv khov rau hauv cov ntaub ntawv siv tsheb). Cov pa roj carbon Vs. Silicon Carbide rau feem ntau daim ntawv thov kom txo tau lub zog noj thiab muab lub neej ntev. Rau cov ntawv thov tseem ceeb muab ob npaug rau cov tshuab foob feem ntau pom zoo.
Txhua lwm txoj hauv kev tawm hauv lub tshuab foob raug thaiv nrog kev siv tawm lub gasket, o-ring, wedge (Rubber, PTFE lossis Flexible Graphite). Lwm qhov tseem ceeb ntawm lub tshuab twj tso kua mis foob yog yuav ua li cas tuav lub foob. Springs (ib zaug los yog ntau), ib lub tshuab nqus hlau los yog cov elastomers tsuas yog siv los muab lub zog xav tau kom nias lub foob ntsej muag ua ke. Lub load lub foob ntsej muag tau txais yog engineered rau hauv tus tsim ntawm lub foob. Qhov kev xaiv ntawm dab tsi yog qhov zoo tshaj plaws nyob ntawm qhov kub thiab txias, thiab qhov xwm txheej ntawm qhov raug kaw (viscosity, abrasiveness, hnyav (nws puas yog slurry?)).
Mechanical seals yog engineered rau feem ntau cov twj tso kua mis, tov khoom thiab agitator daim ntaub ntawv hauv kev saib xyuas. Feem ntau cov qauv tsim tau raug pov thawj tias yog cov neeg ua haujlwm ntau xyoo ntawm kev siv. Hauv lwm cov ntsaws ruaj ruaj yuav tsum tau tsim los hloov kho cov kev xav tau ntawm kev lag luam. Qhov yooj yim rotating ntsej muag mechanical seal tsim yog hloov tau los ua haujlwm rau ntau hom kev sib khi nrog rau compressors. Standard mechanical seals tuaj yeem ua tau raws li qhov yuav tsum tau ua rau qhov kub ntawm 500 degrees F thiab ncej ceev mus rau 3600 RPM. Kev xaiv hom kev foob thib ob feem ntau txiav txim siab qhov ntsuas kub thiab tshuaj muaj peev xwm ntawm lub foob. Kev sib xyaw ntawm cov ntaub ntawv siv nyob rau hauv lub rotating thiab nyob ruaj ruaj lub ntsej muag txhais cov abrasive kuj, thiab tshuaj tsis kam. Kev sib txuas ntawm lub ntsej muag tseem yuav txiav txim siab seb lub zog siv los ntawm lub twj tso kua mis, tov khoom, agitator lossis compressor. Lub ntsej muag foob tuaj yeem sib npaug kom tso cai siab dua sealing. Cov ntsaws ruaj ruaj tuaj yeem kaw qhov siab tshaj 200 psi, los yog siv ntau theem rau kev kub siab dua lossis tshwj xeeb tshaj yog cov kev pabcuam dej hnyav.OEM mechanical sealstuaj yeem muab kho kom tau raws li qhov xav tau tshaj plaws ntawm cov ntawv thov kev lag luam xav txog siab, kub, ceev lossis kua dej.
