Metric O-rings ua haujlwm tib yam li imperial ntsuas qhov system O-rings tab sis yog tsim los siv metric ntsuas rau OD, ID, thiab hla ntu profile. Lawv tau tsim los siv rau hauv cov teb chaws uas siv cov metric system rau kev tsim cov tshuab thiab khoom siv. Cov tuam txhab lag luam feem ntau muab O-rings hauv ob qho tib si imperial thiab metric ntsuas thiab muaj nyob rau hauv tib cov ntaub ntawv raws li cov tsim siv lub imperial ntsuas system.
Kev tu kom zoo ntawm O-Rings
Kev teeb tsa
Thawj kauj ruam hauv kev saib xyuas O-ring yog thaum lub sijhawm teeb tsa. Thaum lub sij hawm kev teeb tsa, kev saib xyuas yuav tsum tau saib xyuas kom ntseeg tau tias qhov zawj lossis caj pas tsis muaj ib qho hlau uas yuav txiav los yog tho lub O-ring. Lub O-ring yuav tsum tau muab tso rau kom zoo yam tsis muaj kev sib tw lossis torquing nws, uas tuaj yeem ua rau lub foob tsis sib xws. Kev lubrication kom raug thiab qhov sib ntxiv ntawm daim kab xev npog yuav muab kev tiv thaiv ntxiv thiab txuas ntxiv qhov txiaj ntsig ntawm O-ring.
Lubrication
Qhov chaw ntawm O-rings yuav tsum muaj txheej nyias ntawm cov roj nplua nyeem, uas yuav ua rau lawv lub neej ntev. Qhov loj tshaj ntawm kev puas tsuaj rau O-ring los tiv thaiv nws los ntawm kev muab lub foob txaus yog thaum nws qhuav tawm.
Ntxuav
O-rings yuav tsum tau ntxuav tsis tu ncua nrog xab npum thiab dej. Cov kuab tshuaj xws li trichlorethylene thiab carbon tetrachloride tuaj yeem ua rau lub nplhaib O-ring puas tsuaj. Cov xab npum thiab dej nrog rau cov methylated ntsuj plig yog qhov teeb meem tsawg tshaj plaws thiab pab tiv thaiv O-ring. Rau qhov laj thawj pom tseeb, txhua yam cuab yeej ntse, txawm tias txhuam hniav yuav tsum zam thaum ntxuav O-ring.
Kev puas tsuaj tshuaj
Thaum lub sij hawm soj ntsuam, O-ring yuav qhia tau tias blistering, tawg, los yog discoloration. Qhov no tuaj yeem tshwm sim los ntawm kev raug tshuaj lom neeg, uas tuaj yeem zam tau los ntawm kev siv cov roj nplua nyeem thiab cov khoom siv O-ring.
Hloov
Ib txoj cai yooj yim rau txhua yam khoom siv tshuab yog kom muaj kev hloov ntawm tes. Nyob rau hauv cov ntaub ntawv ntawm O-rings, lawv yuav tsum tau ua tib zoo khaws cia nyob rau hauv chav tsev kub thiab deb ntawm ultraviolet los yog lub hnub ci teeb, uas yuav ua rau puas O-ring txheej txheej.
o
Kev o tuaj yeem pom tau thaum O-ring tsis tshua muaj thiab flattened. Nyob rau hauv cov ntaub ntawv no, lub O-ring tau coj ib tug mus tas li teeb thiab tsis rov qab los ntawm compressed ua rau ib tug feem pua poob nyob rau hauv compressive muaj peev xwm. Qhov no tuaj yeem zam tau los ntawm kev ua kom ntseeg tau tias O-ring tsis dhau compressed.
Thermal Degradation
Thermal degradation tuaj yeem zam tau nrog kev xaiv ntawm cov khoom siv O-ring kom raug thiab tsis muab tso rau hauv cov xwm txheej uas dhau qhov ntsuas kub. Qhov kub thiab txias tuaj yeem ua rau qhov elasticity ntawm O-ring thiab ua kom nws cov tawv tawv.
Extrusion
Extrusion yooj yim pom. O-rings muab tso rau nruab nrab ntawm ob qhov chaw ua lub sealant. Thaum qhov chaw sib ntsib, ib feem ntawm O-ring tuaj yeem ntes tau nyob nruab nrab, uas yog hu ua extrusion. Yog tias nws mus tsis tau kho, seepage thiab xau tuaj yeem tshwm sim. Nws yog ib qho tseem ceeb kom hloov O-ring tam sim ntawd.
Kev puas tsuaj
Txhua daim ntawv ntawm lub teeb lub zog siab tuaj yeem ua rau O-ring puas tsuaj. Qhov no tshwm sim vim muaj kev sib cuam tshuam ntawm cov khoom siv hauv O-ring thiab wavelengths ntawm lub teeb uas ua rau tawg ntawm O-ring thiab to.
Kev puas tsuaj
Ib qho kev puas tsuaj ntau tshaj plaws rau O-ring foob qhov chaw yog kev puas tsuaj uas ua rau lub foob ntawm daim ntawv thov. Kev sib txhuam ntawm lub nplhaib thiab vaj tse heats O-ring nto, uas ua rau kom muaj kev sib txhuam thiab hloov cov yam ntxwv ntawm O-ring muaj pes tsawg leeg. Qhov tshwm sim ntawm qhov nce hauv kev sib txhuam los ntawm kev puas tsuaj ua rau hnav thiab tsim kua muag ntawm O-ring nrog rau kev tsim ntawm lacerations ntawm nws qhov chaw.
