O-ntuag puas yog Simply Impossible

Tsis ua rau tuaj yeem ua rau lub tshuab xiam oob qhab thiab khoom siv, tab sis thaum muaj ib qho tshiab tsis ua hauj lwm hom, qhov xav tau qee cov kev tshawb fawb ntxiv. Nyob rau hauv rooj plaub no, ib qho kev sib txuam ntawm ntau yam yuav tsim tau lub tswv yim tshiab rau kev tsis ua O-Ring.

Nyob hauv daim ntawv sau npe, aircraft roj twj manufacturers tau hu rau Parker Hannifin kom pab daws teebmeem O-gasket tsis ua hauj lwm uas ua rau muaj teeb meem dim pa. Lub Rau Hli Ntuj 2008 thiab Lub Xya Hli, peb nyias aircraft roj twj yog nqa tawm txhua hnub. Hauv tag nrho peb qho piv txwv, cov roj gas O cov khoom siv los ntawm cov khoom siv ua lag luam thiab cov roj twj tau muab sib dhos ua ntej qhov kev pabcuam hauv lub nkoj, huas dhau kev kuaj cov kabmob. Li hauv ob lub hlis, txhua yam kho cov twj muaj cov cim qhia roj ntub. Tom qab disassembly, tag nrho peb O-ring yog tawg ntawm lub zawj, thiab txhua so ua ib qho 90 ° khoov

Ib kauj ruam tseemceeb hauv kev ntsuam xyuas uas tsis ua haujlwm no yog kev ntsuam xyuas txhua yam ntawm kev ua haujlwm rau O-Ring. Obviously, tag nrho peb O-nplhaib tau puas lawm, uas yuav ua rau kom to taub. Kuj ceeb tias, tag nrho peb O-nplhaib tau ruptured nyob rau hauv cov kev coj ntawm lub siab qhov chaw, es tsis deviating los ntawm nws. Txawm li cas los, ignoring lwm yam ua rau tej zaum yuav ua rau kev tsis ua hauj lwm yuav ua rau cov tsis saib xyuas ntawm ntau yam tseem ceeb heev uas yuav ua rau qhov zoo tshaj plaws precautionary mus kom ze. Hauv qhov piv txwv ntawm qhov xwm txheej no, O-washers tsis tsim lwm yam khoom kho kev puas tsuaj. Piv txwv li, qhov O-ring no tsis muaj pov thawj ntawm kev tha plab tsis thwj tawm, thaum lub siab ceev tshaj lub zog ntawm cov khoom, rubber yuav muab tso rau qhov sib txawv ntawm cov khoom siv, tawm hauv qhov "kev puas tsuaj" Rubber thaj tsam. Qhov no tsis yog nyob ntawm no O-ring. Thiab yog tsis muaj qhov qhia tias O-washers tau tsim txhua txoj kev ntawm compression nruab nrab ntawm assembled qhov chaw.

Tsis tas li ntawd, cov khoom siv roj hmab tsis muaj cov cim qhia txog kev siv tshuaj lom neeg los yog thermal degradation. Tsis zoo li lwm yam kev puas tsuaj, O-Ring muaj qhov tsis tseem ceeb, qhov muag, qhov muag, nplaum, kev ywj siab deformation, kev qaug zog lossis qhov poob ntawm lub zog tensile. Yooj yim heev, tsis muaj kev puas tsuaj rau lwm yam kev puas tsuaj. Rau cov laj thawj no, cov tshuaj thiab cov thermal incompatibility ntawm cov ntaub ntawv sib khi no yuav raug pov thawj los ua ib qho muaj feem cuam tshuam ntawm qhov ua rau tsis ua hauj lwm.

O-type gasket tsis ua hauj lwm yog feem ntau pom tau zoo kom tau raws li daim ntawv thov, O-washers yog ncav lub sijhawm thaum sib sau ua ke. Hauv qhov no, txawm tias cov O-ntxuav tau dhau los kuaj thawj zaug thiab tau siv ntau lub lis piam. Rau qhov puas O-washers nws tseem tsis tau. Yog li, cov roj gas O-type yuav tsum tsis muaj kev puas tsuaj thaum kev teeb tsa thiab thawj zaug kev sim siab. Qhov no txhais tau hais tias qhov O-ring yog puas thaum lub sij hawm siv, uas yog, nws tsis tshua muaj nyob hauv O-lub nplhaib thaum nws muab tso rau hauv lub tank. Kev rhuav tshem ntawm hom kev siv no feem ntau yog taug qab mus rau ib los yog ob qho laj thawj.

Feem ntau ntawm kev siv O-washers yog torn, uas yog kis los ntawm qhov pib twist point. Nyob rau hauv rooj plaub no, ib feem ntawm O-nplhaib yog crushed nyob rau hauv lub fitted hlau feem, feem ntau yog thaum zawj yog accidentally thaum lub installation. O-ntiv nplhaib uas raug puas tsuaj li no yuav ua rau pom kev puas tsuaj, xws li ib nrab crushing, ib nrab ntawm O-ring, thiab cov phiajcim ib nrab ntawm cov ntoo. Qee zaum, ib qho zis O-nplhaib yuav kis tau los ntawm kev kuaj thawj zaug thiab nws puas thaum siv, vim yog thawj zaug ntawm qhov O-Ring. Txawm li cas los xij, tsis muaj ib qho pov thawj ntawm qhov kev puas tsuaj ntawm cov kev ua tsis tau zoo O-nplhaib.

Cov kev siv O-Ring tsawg dua qub vim qhov teeb meem vim yog qhov tawg tsis nyob hauv O-ring. Yog hais tias cov roj hmab cov hluav taws xob ntws tawm thiab cov hlua thaum lub txheej txheem molding, tus kho dua tshiab yog nyob hauv O-cov nplhaib, uas yog yooj yim tuaj yeem ua rau siab. Cov no feem ntau tuaj yeem kuaj tau los ntawm kev tshawb xyuas cov kev kuaj puas lawm. Yog tias cov khoom tsis ua tiav zoo, qhov uas ua rau lub cev yuav ua rau daim ntawv "spherical - and - groove" puas raug, nrog rau qhov sib xyaw ua ke thiab cov duab kos duab. O-shaped gasket hauv cov npuas kom cov khaub hlab zoo li sib txawv, tuaj yeem ua rau lub ntsej muag, ncig thiab xau npo. Thiab nyob rau hauv cov ntaub ntawv no puas cuam tshuam O-ntiv nplhaib muaj qhov sib txawv heev thiab huv sib txawv, zoo li yog ntse los ntawm ib tug ntse riam txiav tib yam. O-ring manufacturing defects txhawm rau ua rau hom kev puas tsuaj no tsuas ua tsis tau. Qhov ntse ntse, tus txha nqaj nti ua pob txha tawg yog zoo ib yaam le lub elongation limit tshaj qhov khoom.
