Vim li cas PTFE Cov Phaj Kub Kub Kub Tshiab Ua Tsis Tau Ua Ntej Ua Ntej Yuav Tshawb Nrhiav Cov Hauv Paus?

Lub hom phiaj - tshiab PTFE cua sov phaj uas tuaj nrog ua tiav daim ntawv pov thawj thiab yuav tsum nyob rau xyoo tsis ua hauj lwm tom qab ob peb lub hlis xwb. Kev tiv thaiv hauv av ua rau tsis muaj zog, cov khoom siv hluav taws xob poob qis, lossis muaj kev puas tsuaj rau saum npoo. Cov lus teb ceev ceev qhia tias muaj qhov tsis zoo hauv cov txheej txheem tsim khoom, thiab tus neeg muag khoom ua txhaum. Tab sis kev tshawb fawb zoo feem ntau pom tias qhov laj thawj tiag tiag yog qhov yuam kev ntawm kev teeb tsa, kev ntxhov siab, cov ntawv thov tsis sib xws, teeb meem hluav taws xob, lossis txawm tias muaj kev cuam tshuam me me. Txhawm rau mus dhau qhov kev kwv yees, cov neeg saib xyuas kev saib xyuas thiab cov kws tsim kho kev ntseeg siab xav tau ib lub hauv paus rau kev tshawb nrhiav qhov ua tsis tiav. Qhov no yuav pab lawv nrhiav qhov tseeb ntawm qhov teeb meem thiab muab tso rau hauv qhov chaw kom cov phaj tom ntej kom tsis txhob muaj teeb meem tib yam.

Kev tshuaj xyuas cov ntaub ntawv

Ua ntej kov lub cuab yeej tawg, xyuas kom koj muaj tag nrho cov ntaub ntawv tsim nyog. Tau txais cov ntaub ntawv teev npe rau lub phaj, qhov yuav tsum tau ua, hnub teeb tsa, daim ntawv teev npe ua haujlwm, thiab cov ntaub ntawv ntxaws txog kev ua haujlwm. Sau cov txheej txheem qub, suav nrog qhov ntsuas kub, hom kev thauj khoom, ib puag ncig, thiab tshuaj lom neeg raug. Tsis tas li sau cov kev hloov pauv uas tshwm sim tom qab ntawd, xws li lub voj voog ua haujlwm ntev dua, cov txheej txheem tshiab, lossis hloov cov qauv ntws. Txheeb xyuas qhov ntsuas qhov ntsuas hluav taws xob tiv thaiv qhov ntsuas lub npe. Kev txo qis txawm tias 10% txiav tawm hluav taws xob ntau dua 20%. Saib rau hauv keeb kwm ntawm kev saib xyuas rau cov khoom tu, mounting torque qhov tseem ceeb, thiab kev soj ntsuam yav dhau los. Cov hauv paus ntsiab lus no txo ​​qis cov kev xav thiab ua kom paub tseeb tias cov dej ntws los yog cov haujlwm ua haujlwm tsis nco qab.

Kev tshuaj xyuas los ntawm kev pom thiab pom cov qauv ntawm kev puas tsuaj

Tsis txhob ntxuav lossis ncaj lub phaj; cia li khaws cia ib yam li thaum koj muab nws tawm. Siv tsawg- lub zog magnification thiab ci, slanted illumination los xyuas kom meej. Daim ntawv qhia qhov kev puas tsuaj nyob rau hauv kev sib raug zoo rau cov ntsiab lus mounting, npoo, ces kaum, thiab cheeb tsam uas nquag cua sov. Ua tib zoo sau ntawv txog qhov zoo li cas:

Yog hais tias qhov saum npoo yog uniformly dawb, tsis yooj yim, los yog muaj nplua crazing nyob rau hauv cov cheeb tsam raug, nws yuav yog ib tug kos npe rau ntawm cov tshuaj puas.

Localized blistering, charring, los yog melting txhais tau hais tias lub kaw lus kub dhau los yog tau qhuav.

Ntxuav, nkig tawg nyob ze ntawm lub qhov los yog cov ces kaum yog cov cim qhia ntawm thermal stress los yog kev co qaug zog.

Dents nrog cov kab nrib pleb uas nthuav tawm qhia tias qee yam tsoo lawv.

Hauv qhov tseeb, txoj haujlwm ntawm qhov tsis ua haujlwm feem ntau nthuav tawm cov lus piav qhia. Piv txwv li, cov kab nrib pleb ze ntawm cov npoo tuaj yeem txhais tau tias kev puas tsuaj thermal, cov kab nrib pleb ze ntawm qhov kub tuaj yeem txhais tau tias muaj teeb meem hluav taws xob, thiab kev hloov pauv ntawm qhov chaw yuav txhais tau tias muaj tshuaj tua kab mob. Cov qauv no tsim cov kev xav tshwj xeeb thiab txiav tawm cov lus piav qhia tsis sib xws thaum ntxov.

Kev txheeb xyuas cov ntaub ntawv ua haujlwm

Tau txais cov ntaub ntawv keeb kwm yav dhau los ntawm lub ntsuas kub, lub zog saib xyuas, thiab lwm yam sensors uas siv tau. Tshawb xyuas qhov kub hnyiab dhau ntawm lub phaj qhov ntsuas qhov txwv, lub sij hawm ntev ntawm tag nrho - lub zog ua haujlwm thaum pib, qhov hloov pauv hluav taws xob, lossis qis - qhov xwm txheej uas tuaj yeem ua rau kub dhau. Saib rau lub sijhawm thaum kev ua haujlwm poob qis thiab muaj kev nchuav, txaws, lossis tsim cov khoom seem. Txhawm rau txuas cov kev ua tsis tiav rau qee cov khoom siv, kev tu lub voj voog, lossis cov txheej txheem hloov pauv, piv cov ntawv teev sijhawm nrog cov ntawv teev ntau lawm. Cov ntaub ntawv ntau feem ntau qhia cov xwm txheej ib ntus uas tsis tuaj yeem pom ntawm qhov muag liab qab.

Kev tsom xam ntawm ib puag ncig thiab raug

Ua kom pom qhov profile tag nrho. Ua ib daim ntawv teev tag nrho cov tshuaj, vapors, fumes, los yog mechanical stress uas lub phaj tau kov nrog, xws li txheej txheem xov xwm, ntxuav cov kev daws teeb meem, pa paug paug, qhov chaw vibration, los yog mechanical contact. suav nrog ntau yam ntawm cov concentration, qhov kub thiab txias, thiab kev hloov pauv hauv pH. Txawm tias siv sijhawm luv luv nrog cov neeg ua haujlwm tsis sib xws (muaj zog oxidisers, fluorinating chemicals, lossis kab peroxides) tuaj yeem pib deterioration uas txuas ntxiv nyob rau hauv ib txwm muaj. Tshawb xyuas cov cuab yeej nyob ib puag ncig koj rau qhov chaw ntawm kev co lossis cua sov uas tuaj yeem ua rau muaj kev ntxhov siab hauv cheeb tsam.

Khaws pov thawj thiab txav mus tom ntej

Ua ntej koj kov lub phaj, thaij duab ntawm ntau lub ces kaum, suav nrog ze -ups ntawm thaj chaw puas. Khaws cov ntaub ntawv ntawm cov saw ntawm kev saib xyuas rau cov qauv xa mus rau cov chaw kuaj mob. Cov neeg feem ntau pov tseg cov phaj tsis zoo yam tsis tau saib rau hauv lawv, txawm li cas los xij lub tsev ua tsis tau zoo yog qhov zoo tshaj plaws ntawm cov ntaub ntawv hais txog qhov tsis raug. Thaum pom cov pov thawj thiab keeb kwm tseem tsis tau meej meej, ua qee qhov kev sim tsis zoo -kev puas tsuaj: ntsuas kev tiv thaiv hluav taws xob (nws yuav tsum ntau dua 100 MΩ ntawm 500 V DC), ntsuas qhov hnyav hloov, thiab ntsuas qhov tawv. Txhawm rau nrhiav qhov laj thawj ntawm qhov teeb meem, koj yuav tsum tau hu rau lub chaw tsim khoom lossis ib lub chaw kuaj mob ywj pheej los ua qhov kev soj ntsuam zoo, xws li scanning electron microscopy, Fourier-hloov infrared spectroscopy, lossis elemental mapping. Cov txheej txheem no tuaj yeem pom cov txheej txheem degradation me me.

Kev ntsuam xyuas zoo hloov pauv qhov kev ntxhov siab mus rau hauv txoj hauv kev los kawm uas txwv kev ua tsis tiav yav tom ntej. Es tsis txhob tos rau ib yam dab tsi tawg thiab tom qab ntawd hloov nws, kev tiv thaiv cov cuab yeej cuab tam muaj xws li hauv paus ua rau kev soj ntsuam, kev tshawb nrhiav tsis ua hauj lwm, kev kuaj xyuas tus qauv puas, pov thawj pov thawj, thiab kev kuaj mob. Rau qhov nyuaj lossis rov ua tsis tiav, ntiav ib lub chaw soj ntsuam tsis ua haujlwm sab nraud tuaj yeem muab cov lus teb rau koj tias koj tus kheej lub chaw kuaj tsis tuaj yeem ua tsis tau. Cov txheej txheem tshwj xeeb feem ntau pom muaj kev sib koom ua ke, cov khoom tsis zoo uas tsis tau sau tseg, lossis kev teeb tsa yuam kev uas cov kev ntsuam xyuas sab hauv tsis pom. Qhov no tso cai rau kev txhim kho tas mus li thiab ua kom paub tseeb tias yav tom ntej PTFE cua sov daim hlau kav lawv lub neej tsim tag nrho hauv cov chaw tsim khoom tawv.
