Hauv kev tsim cov khoom siv hluav taws xob, qhov tseeb ntawm cov ntawv luam tawm Circuit Board (PCBS) yog qhov tseem ceeb, vim nws cuam tshuam ncaj qha rau kev teeb tsa ntawm cov khoom siv hluav taws xob tom ntej thiab kev ua haujlwm ntawm circuits. Thaum lub sij hawm siv cov tsoos cam khwb cia hlau puag, qhov teeb meem kev co feem ntau ua rau lub PCB qhov hloov, uas tau dhau los ua ib qho teeb meem loj txwv kev txhim kho ntawm qhov raug drilling. Lub hauv paus granite, nrog nws cov khoom tshwj xeeb lub cev thiab cov qauv zoo, muab kev daws teeb meem zoo rau qhov teeb meem no.
Lub hauv paus ua rau borehole sib txawv los ntawm cam khwb cia hlau vibration
Lub ntuj zaus ntawm cov khoom siv cam khwb cia hlau yog qhov tsawg. Thaum lub sijhawm ua haujlwm ntawm cov khoom siv drilling, tshwj xeeb tshaj yog thaum lub tshuab ua haujlwm siab ceev tig los rau hauv kev sib cuag nrog cov ntawv hlau, resonance yog qhov tshwm sim. Qhov no resonance yuav ua rau lub hauv paus hlau cam khwb cia ua kom muaj kev vibrations uas tsis tuaj yeem tsis quav ntsej. Txawm tias qhov me me kev vibration amplitude yuav tsis tu ncua thiab nthuav dav thaum lub sijhawm ua haujlwm zoo drilling, nws thiaj li ua rau lub laum me ntsis deviating los ntawm qhov pib qhov chaw drilling. Tsis tas li ntawd, damping kev ua tau zoo ntawm cov cam khwb cia hlau puag yog txwv, ua rau nws nyuaj rau ceev ceev attenuate lub zog vibration, ua rau lub sij hawm ntev kev co thiab ntxiv intensifying lub degree ntawm borehole offset.
Cov yam ntxwv zoo heev los tiv thaiv kev vibration ntawm granite puag
Granite muaj zoo damping zog. Nws sab hauv pob zeb siv lead ua qauv yog compact thiab tuaj yeem nqus tau zoo thiab siv lub zog vibration. Thaum cov khoom siv drilling ua haujlwm thiab tsim kev co, lub hauv paus granite tuaj yeem txo qhov amplitude ntawm kev vibration hauv lub sijhawm luv luv. Kev tshawb fawb qhia tau hais tias qhov damping piv ntawm granite yog ob peb zaug ntawm cam khwb cia hlau. Qhov no txhais tau hais tias nws tuaj yeem hloov pauv feem ntau ntawm lub zog vibration mus rau hauv lub zog hluav taws xob thiab lwm yam kev siv hluav taws xob hauv ib qho tam sim thiab dissipate lawv, yog li txo qhov cuam tshuam ntawm kev vibration ntawm kev ua haujlwm drilling, kom ntseeg tau tias cov laum me ntsis tuaj yeem ua haujlwm ruaj khov raws li qhov kev npaj ua ntej, thiab txo qhov tshwm sim ntawm offset phenomena.
Guarantee ntawm siab rigidity thiab stability
Lub hauv paus granite kuj muaj qhov tsis tshua muaj siab rigidity thiab stability. Nws qhov ceev yog qhov siab thiab nws lub zog compressive ntau dua li cov hlau cam khwb cia. Thaum lub sij hawm cov txheej txheem drilling, nws tuaj yeem tiv taus qhov kev siv ntau heev los ntawm kev xyaum me ntsis thiab ntau yam kev ntxhov siab uas tau tsim los ntawm kev ua haujlwm ntawm cov cuab yeej siv, thiab tsis ua rau deformation. Txawm tias nyob rau hauv lub sij hawm ntev kev lag luam los yog kev cuam tshuam me me, lub hauv paus granite tuaj yeem tswj kev ruaj ntseg ntawm nws cov qauv thiab muab cov khoom siv thiab txhim khu kev qha rau cov khoom siv drilling. Qhov kev txhawb nqa ruaj khov no ua kom ntseeg tau tias cov haujlwm txheeb ze ntawm txhua feem ntawm cov khoom siv drilling nyob twj ywm txhua lub sijhawm, yog li lav qhov siab ntawm qhov drilling.
Qhov zoo ntawm thermal stability zam kev co ntxiv
Ntxiv nrog rau nws cov kev vibration tsis kam, thermal stability ntawm granite kuj zoo heev. Thaum lub sij hawm drilling txheej txheem, kev sib txhuam ntawm lub laum me ntsis thiab cov ntawv hlau ua kom muaj cua sov, thiab kev ua haujlwm ntawm cov khoom siv kuj tuaj yeem ua rau qhov kub thiab txias. Lub hauv paus cam khwb cia hlau cuam tshuam zoo heev los ntawm kev hloov pauv kub. Thermal expansion thiab contraction tau yooj yim ua rau ntxiv deformation thiab vibration, uas cuam tshuam nrog qhov tseeb drilling. Lub coefficient ntawm thermal expansion ntawm granite yog tsawg heev. Thaum qhov kub thiab txias hloov pauv, nws qhov kev hloov pauv yuav luag tsis quav ntsej. Qhov no zam qhov kev vibration ntxiv los ntawm thermal deformation, tsim kom muaj qhov chaw ua haujlwm ruaj khov dua rau kev ua haujlwm drilling, thiab ntxiv txo qhov muaj peev xwm ntawm drilling offset.
Nyob rau hauv kev nrhiav cov high-precision PCB drilling ua hauj lwm, lub granite puag, nrog nws zoo heev kev co kuj, siab rigidity, siab stability thiab zoo heev thermal stability, zoo daws qhov drilling offset teeb meem tshwm sim los ntawm cam khwb cia hlau vibration los ntawm ntau yam. Nws muab kev txhawb nqa zoo dua rau cov khoom siv PCB drilling, pab cov khoom siv hluav taws xob tsim hluav taws xob tsim cov khoom siv hluav taws xob zoo dua qub, thiab txhawb nqa tag nrho kev lag luam los txhim kho cov kev taw qhia meej dua thiab qib siab.
