Cov qauv ntawm cov seismic kev rho tawm rau cov choj tsis yog suav nrog cov seismic roj hmab bearings, thiab nws cov qauv tshwj xeeb yog raws li hauv qab no:
Cov Txheej Txheem Yooj Yim: cov seismic cable roj hmab bearings yog tsim ntawm ntau txheej ntawm roj hmab thiab ntau txheej txheej ntawm cov phiaj hlau stacked hloov lwm yam. Feem ntau suav nrog ntau ntu xws li daim npog sab saud, cov kab mob qis dua, cov roj hmab rho cov nplaim thiab bolts. Daim npog sab saud yog siv los txhawb lub tsev sab saud lossis tus choj, thiab cov kab mob qis dua txuas nrog lub hauv paus los ntawm cov kabmob los hloov phaus thiab thauj khoom. Seismic rho roj hmab yog ib qho tseem ceeb, feem ntau ua los ntawm high-nruj thiab nro muaj peev xwm txo cov av qeeg ntawm tsev qauv.
Hom: cov seismic kev rho tawm roj hmab bearings tuaj yeem faib ua se seismic cais bearings thiab choj seismic sib cais bearings raws li lawv siv. Raws li kev tsim khoom lag luam, lawv tuaj yeem muab faib ua peb hom: Lead-dawb hom roj hmab bearings (coj hom lrb / gzy), thiab siab damping roj hmab bearings (HDR). Cov roj hmab muaj kev cuam tshuam cov khoom siv ntuj ua cov roj hmab nyoos, ua rau cov roj hmab ua kom ntub dej muaj lwm cov roj hmab txhawm rau txhim kho cov khoom siv damping.
