Tusv/ Sarodil36 /Feni36Hlau rau Sealing Iav
Kev faib tawm: Tsawg coefficient ntawm thermal expansion alloy
Daim Ntawv Thov:Tusvyog siv qhov chaw siab ruaj khov yog qhov yuav tsum tau ua, cov moos Seismic, cov ntsej muag paj nruag cheats Hauv av kev soj ntsuam, thaum ua ntej-kev txiav txim (theem siab-precision theem yog yuav tsum tau ua, es tsis txhob ntoo, fiberglass, lossis lwm yam hlau. Invar struts tau siv nyob rau hauv qee lub pistons kom txwv lawv cov cua sov nthuav dav hauv lawv cov thooj voos kheej kheej.
