Lub geophone yog ib qho khoom siv hluav taws xob hloov pauv hluav taws xob uas hloov cov seismic nthwv dej xa mus rau hauv av lossis dej rau hauv cov teeb liab hluav taws xob.Nws yog ib qho tseem ceeb ntawm cov ntaub ntawv nrhiav tau ntawm seismographs.Hluav taws xob geophones feem ntau yog siv rau hauv av seismic kev tshawb nrhiav, thiab piezoelectric geophones feem ntau yog siv nyob rau hauv offshore seismic tshawb nrhiav.
Lub geophone yog tsim los ntawm cov hlau nplaum ruaj khov, coil thiab daim ntawv caij nplooj ntoos hlav.Cov hlau nplaum muaj zog hlau nplaum thiab yog qhov tseem ceeb ntawm geophone;lub coil yog ua los ntawm tooj liab enameled hlau qhov txhab ntawm tus ncej thiab muaj ob qhov tso zis terminals.Nws kuj yog geophone Qhov tseem ceeb ntawm lub cuab yeej;lub caij nplooj ntoos hlav daim yog ua los ntawm tshwj xeeb phosphor bronze rau hauv ib tug tej yam duab thiab muaj ib tug linear elastic coefficient.Nws txuas lub kauj thiab lub hau yas ua ke, kom lub kauj thiab cov hlau nplaum tsim ib qho kev txav ntawm lub cev (inertial lub cev).Thaum muaj cov neeg kho tshuab kev co hauv av, lub coil txav mus rau cov hlau nplaum los txiav cov kab sib nqus.Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, induced electromotive quab yuam yog generated nyob rau hauv lub kauj, thiab qhov loj ntawm induced electromotive quab yuam yog proportional rau tus txheeb ze zog ceev ntawm lub kauj thiab cov hlau nplaum.Qhov kev simulation ntawm cov coil tso zis Cov teeb liab hluav taws xob yog ua raws li txoj cai hloov ceev ntawm av txhua yam kev co.
Lub EG-4.5-II geophone 4.5Hz yog ib tug tsawg-frequency geophone, thiab lub coil system yog ib tug rotating coil qauv, uas yuav zoo tshem tawm cov lateral kev quab yuam.
Lub geophone tsim nyog rau ntau yam kev ntsuas kev vibration xws li geophysical prospecting thiab engineering vibration ntsuas.
Nws tuaj yeem siv los ua ib qho taw tes geophone thiab peb feem geophone.
Nws muaj ob hom ntsug yoj thiab kab rov tav yoj, uas tuaj yeem siv tau yooj yim.
Nws yog sib npaug rau SM-6 B coil 4.5hz geophone.
Dav siv nyob rau hauv industrial vibration-saib tshuab.
Qhov zoo tshaj plaws xaiv rau shear-yoj kab rov tav hais.
