Rau qhov xav txog thaum xaiv cov ntxhua khaub ncaws

Cov tshuab ntxhua khaub ncaws yog cov khoom siv dav siv. Vim lawv cov nqi tsim khoom tsawg thiab ntau yam kev siv, muaj ntau yam khoom siv gasket nyob rau hauv kev ua lag luam, thiab yuav ua li cas xaiv lawv tau dhau los ua kev sib tw. Hauv qab no, Yuantian tau sau rau 6 yam los xav txog thaum xaiv cov ntxhua khaub ncaws, raws li hauv qab no:
1. Pre nruj npaum li cas
Feem ntau, cov ntsaws ruaj ruaj yog ntsia hauv grooves. Txhawm rau kom ntseeg tau tias cov nyhuv sealing yuav tsum tau khaws cia thawj zaug. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias tus nqi ua ntej nruj nws txawv nyob ntawm qhov chaw siv.
2. Stretching thiab zawm
Lub stretching thiab zawm qhov tseem ceeb yuav tsum tsim nyog, tsis loj los yog me me. Yog hais tias qhov stretching thiab zawm qhov tseem ceeb yog loj heev, nws yuav ua rau tus ntoo khaub lig-section ntawm sealing lub ntsiab kom dhau los yog txo. Ib zaug ncab los ntawm 1 feem pua, txoj kab uas hla hla yuav txo los ntawm 0.5 feem pua ​​.
3. Kev tshaj tawm txoj haujlwm thiab kev ua haujlwm
Nws yog ib qho tsim nyog yuav tsum xav txog qhov sib xws ntawm qhov nruab nrab ua haujlwm, nrog rau qhov siab, qhov kub thiab txias, kev sib txuas lub sijhawm ua haujlwm, lub voj voog ua haujlwm, thiab lwm yam kev mob ntawm qhov chaw sib khi. Yog tias cov khoom sib khi yog siv nyob rau hauv cov xwm txheej rotating, nws tseem yuav tsum tau xav txog qhov kub thiab txias tshwm sim los ntawm kev sib txhuam kub.
4. Txoj kev sib khi
Raws li qhov teeb meem ntawm kev thauj khoom, nws tuaj yeem muab faib ua static sealing thiab dynamic sealing. Raws li lub hom phiaj ntawm kev sib khi, nws tuaj yeem muab faib ua rotary sealing, qhov sealing, thiab ncej sealing. Raws li hom ntaus ntawv, nws tuaj yeem muab faib ua axial thiab radial li.
5. Hardness
Lub hardness txiav txim siab npaum li cas nruj thiab groove extrusion sib txawv, uas yog lub ntsiab yam tseem ceeb cuam tshuam rau sealing.
6. Tight thiab pheej deformation
Nyob rau hauv lub zog ntawm lub siab, lub sealing lub sij hawm kuj undergo elastic deformation. Txhawm rau kom tsis txhob deformation tsis tu ncua, qhov nruj ntawm lub gasket yuav tsum tau tswj ntawm 30 feem pua ​​​​rau 20 feem pua.
