Taw qhia
Kev hnav tsis kam ntawm sealing rings yog qhov tseem ceeb rau kev tswj xyuas kev ua haujlwm tsis tu ncua thiab nce kev pabcuam lub neej hauv cov cuab yeej siv tshuab thiab tsheb. Cov ntawv tshaj tawm no yuav muab ob peb txoj kev siv dav thiab kev ntsuas los ntsuas kev sib khi rings 'tsis kam hnav.
Kev xaiv khoom
Ib qho ntawm cov ntsiab lus tseem ceeb cuam tshuam rau kev hnav tsis kam yog lub nplhaib sealing cov khoom xaiv. Polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), fluororubber (FKM), thiab lwm cov tshuaj nquag siv los tiv thaiv hnav. Cov ntaub ntawv no yog siv tau ntev thiab hnav-tiv taus, thiab lawv tuaj yeem ua haujlwm tsis tu ncua hauv cov xwm txheej uas muaj kev sib txhuam rau lub sijhawm ntev.
Kev sib txhuam coefficient
Ib qho kev ntsuas tseem ceeb rau kev ntsuam xyuas lub nplhaib sealing 'tsis kam hnav yog lawv cov kev sib txhuam coefficient. Kev sib txhuam tester lossis cov cuab yeej ntsuas kev sib txhuam tuaj yeem siv los ua kev sib txhuam coefficient. Ib qho nyiaj ntawm qhov siab thiab ceev yog siv thaum lub nplhaib sealing nyob rau hauv kev sib cuag nrog cov khoom sib txhuam, uas feem ntau yog ib qho kev txav ntawm cov hlau, thoob plaws hauv qhov kev xeem. Qhov piv ntawm kev siv dag zog rau kev sib txhuam yog ntsuas los txiav txim siab coefficient ntawm kev sib txhuam. Lub nplhaib sealing nrog qis kev sib txhuam coefficient zoo dua hnav.
Hnav kuaj
Ib qho txheej txheem nrov rau kev ntsuas kev sib khi rings 'tiv taus hnav yog kuaj hnav. Sliding wear testing thiab reciprocating wear testing yog ob txoj kev sim hnav nrov. Kev xeem zawv zawg hnav yuav txav cov khoom sib txhuam thiab lub nplhaib foob nyob rau hauv kev sib raug zoo. Qhov loj poob lossis qhov hloov pauv ua ntej thiab tom qab hnav yog siv los txiav txim siab qhov hnav. Nyob rau hauv lub reciprocating hnav xeem, qhov reciprocating kev sib txhuam kev ua nyob rau hauv lub ntiaj teb no kev ua hauj lwm tshwm sim yog simulated nyob rau hauv thiaj li yuav ntsuam xyuas lub sealing nplhaib lub hnav tsis kam.
Kev sim ua haujlwm tiag tiag
Kev sim ua nyob rau hauv lub ntiaj teb ua haujlwm ib puag ncig tuaj yeem pab txiav txim siab lub nplhaib sealing qhov hnav tsis kam ntau dua. Nruab lub nplhaib sealing ntawm lub tshuab tiag tiag lossis tshuab thiab ua haujlwm raws li qee qhov kev ua haujlwm rau lub sijhawm ntev. Ntsuas lub nplhaib sealing lub neej thiab hnav tsis kam los ntawm kev saib xyuas thiab sau cov ntaub ntawv hnav thaum siv.
Hauv kev xaus
Kev ntsuas qhov hnav tsis kam ntawm sealing rings yog ib qho kev ntsuas tseem ceeb hauv kev lav qhov tsim nyog ua haujlwm thiab ua kom lub neej ntev ntawm cov cuab yeej. Lub nplhaib sealing kev ua tau zoo ntawm kev hnav-tiv taus tuaj yeem raug soj ntsuam zoo los ntawm kev xaiv cov khoom siv tiv thaiv kev hnav, kev sib txhuam coefficient, kev kuaj hnav, thiab kev sim hauv kev ua haujlwm tiag tiag. Qhov no yuav pab xaiv cov khoom siv foob thiab tsim kom zoo, txhim kho lub neej thiab kev cia siab ntawm cov khoom siv.
