1.Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau?
Qhov ncaj qha ua rau wrinkling yog cov khoom siv ntau dhau.
Kev Ua Haujlwm: Ua kom lub zog ntawm lub cev tsis muaj zog los ntawm 10% -20% thiab saib seb cov wrinkles puas ploj mus.
Kev Tshawb Fawb: Yog tias wrinkling tsawg dua tab sis cov phab ntsa pib whiten (thinning), nws qhia tau hais tias qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm mus txog nws qhov tseem ceeb thiab yuav tsum tau kho nrog lubrication.
Tswv yim: Rau cov tuag nrog cov hlaws dai, ua kom lub zog ntawm lub cev muaj zog tuaj yeem sib npaug los ua kom cov hlaws dai los ntawm kev sib tsoo cov hlaws zawj.
2.Yuav ua li cas kho lub lubrication zoo?
Txo lubrication nyob rau hauv lub flange cheeb tsam: Wrinkling qhia tias cov khoom yog ntws sai heev. So tawm cov roj nplua nyeem nyob rau hauv qhov chaw flange nrog ib daim ntaub qhuav, los yog hloov mus rau cov roj viscosity qis kom muaj kev sib txhuam.
Daim ntawv thov Spot: Lubricate tsuas yog cov chaw uas tsis wrinkle, thiab qhuav - so cov chaw wrinkled.
3.Yuav ua li cas polish lub vojvoog (R) ntawm cov kab noj hniav tuag?
Cov tsos mob: Flange wrinkling, nrog rau kev pheej hmoo ntawm sab phab ntsa tearing.
Kev daws: Txo lub vojvoog (R) ntawm qhov tuag inlet-R lub kaum sab xis me me ua rau muaj kev tawm tsam thiab txo qis wrinking. Txawm li cas los xij, nco ntsoov tias R lub kaum sab xis me me heev tuaj yeem ua rau tawg; yuav tsum nrhiav tau ib tug tshuav nyiaj li cas.
Pom zoo tus nqi: Feem ntau 4 ~ 6 npaug ntawm phaj thickness; Nyob rau hauv cov xwm txheej hnyav ntawm wrinkling, nws tuaj yeem txo mus rau 3 npaug ntawm lub phaj thickness.
4.Dab tsi yog qhov cuam tshuam ntawm qhov muaj zog tawm los tsawg dhau?
Cov khoom yog mos heev thiab tsis rigidity, ua rau wrinkling txawm me ntsis kuj.
Qhov pib: Thaum lub zog tawm los ntawm qhov sib sib zog nqus - cov khoom kos duab yog<140MPa, the tendency to wrinkle increases significantly.
Kev daws: Siv ib pawg ntawm tib qib tab sis nrog lub zog tawm los ze dua rau qhov txwv siab (piv txwv li, rau SPCC, xaiv ntau dua lossis sib npaug rau 180MPa).
5.Dab tsi yog qhov cuam tshuam ntawm thickness sib txawv (tsis zoo kam rau ua)?
Cov tsos mob: Tsis ruaj khov wrinkling thoob plaws hauv yob, qee zaum zoo, qee zaum tsis zoo.
Mechanism: Cov ntawv nyias nyias → qhov sib txawv loj ntawm lub nplhaib siab → tsis tuaj yeem tuav daim ntawv nyob rau hauv qhov chaw.
Solution: Measure the actual thickness. If the negative tolerance is >5% thiab wrinkling persists, rov qab los yog downgrade yog pom zoo.
