Siv cov khoom siv elastic sealing thiab me me actuator thrust kom tau cua npuas nruj foob, compress lub valve lub rooj sealing kev ntxhov siab kom elastically deform cov ntaub ntawv thiab nyem rau hauv qhov ntxhib nto ntawm qhov sib txuam hlau los thaiv txhua txoj hauv kev. Lub permeability ntawm cov khoom yog lub hauv paus rau me me to ntawm cov kua.
Cov ntaub ntawv uas yog mos heev, los yog nthuav tawm qhov txias deformation (creep) nyob rau hauv load, tuaj yeem stiffened nrog fillers xws li fiberglass. Yog tias nws yog siv los ua cov ntawv nyias, nws tseem tuaj yeem ua tau raws li qhov yuav tsum tau siv, thiab tuaj yeem tshem tawm qhov txias deformation lossis deformation mus tas li.
Lub foob yuav tsum tau ua tib zoo xyuas kom tsis txhob muaj qhov sib tsoo thiab cov pa tawm vim qhov sib txawv ntawm qhov sib txawv. Kev sib khi cov rooj zaum rau cov hlau yog ib qho kev daws teeb meem, tab sis tsis yog kev daws teeb meem, vim tias daim ntawv cog lus tuaj yeem tawg thiab ua tsis tau thaum raug thermal shock. Ib tug loj txaus siab poob yuav rhuav tshem cov khoom sib txuas.
