Hlau Detector nta thiab tswv yim
Kev nyab xeeb thiab kev ntseeg siab ntawm cov hlau ntes yog nyob ntawm qhov kev ruaj ntseg ntawm qhov zaus ntawm lub tshuab hluav taws xob electromagnetic, feem ntau siv cov zaus ua haujlwm ntawm 80 txog 800kHz. Qhov qis dua qhov ua haujlwm zaus, qhov zoo dua qhov kev kuaj pom ntawm hlau; qhov siab dua qhov ua haujlwm zaus, qhov zoo dua qhov kev kuaj pom ntawm cov pa roj carbon siab. Qhov rhiab heev ntawm tus ntes tau txo qis nrog qhov nce ntawm qhov kev tshawb pom, thiab qhov loj ntawm lub teeb liab induction nyob ntawm qhov loj thiab conductivity ntawm cov hlau hais.
Vim tam sim no pulsation thiab tam sim no filtering, hlau detectors muaj tej yam kev txwv ntawm conveying ceev ntawm cov khoom kuaj. Yog tias qhov kev xa khoom ceev tshaj qhov tsim nyog, qhov rhiab heev ntawm tus ntes yuav poob.
Txhawm rau kom ntseeg tau tias qhov rhiab heev tsis poob, lub ntsuas hlau tsim nyog yuav tsum raug xaiv los hloov kho rau cov khoom kuaj pom. Feem ntau hais lus, qhov kev tshawb nrhiav ntau yuav tsum tau tswj kom muaj tus nqi tsawg kawg nkaus kom ntau li ntau tau. Rau cov khoom lag luam uas muaj qhov zoo ntawm qhov kev xav tau zoo, qhov loj ntawm lub tshuab ntes channel yuav tsum phim cov khoom loj. Kev hloov kho ntawm qhov kev tshawb pom rhiab heev yuav tsum tau txiav txim siab nrog kev siv rau qhov chaw nruab nrab ntawm qhov ntsuas qhov ntsuas, uas muaj qhov qis tshaj induction. Kev kuaj xyuas tus nqi ntawm cov khoom yuav hloov nrog kev hloov pauv ntawm cov khoom siv, xws li kev hloov pauv ntawm qhov kub thiab txias, cov khoom loj, av noo, thiab lwm yam, uas tuaj yeem hloov kho thiab them nyiaj los ntawm kev tswj hwm kev ua haujlwm.
Cov pob yog rov ua dua, muaj qhov tsawg tshaj plaws ntawm qhov chaw, thiab yog qhov nyuaj tshaj plaws rau cov hlau ntes kom ntes tau. Yog li ntawd, spheroid tuaj yeem siv los ua tus qauv siv rau kev tshawb pom rhiab heev. Rau cov hlau tsis yog kheej kheej, qhov kev tshawb pom rhiab heev nyob ntawm qhov chaw ntawm cov hlau. Cov haujlwm sib txawv muaj qhov sib txawv ntawm qhov sib txawv, thiab cov txiaj ntsig kev tshawb pom kuj txawv. Piv txwv li, thaum dhau longitudinally, hlau yog rhiab dua; thaum siab carbon steel thiab non-ferrous yog tsawg rhiab heev. Thaum hla kab rov tav, hlau tsis tshua muaj rhiab heev, thaum siab carbon steel thiab non-ferrous yog rhiab dua.
Hauv kev lag luam khoom noj khoom haus, tshuab feem ntau siv ntau zaus ua haujlwm. Rau cov khoom noj xws li cheese, vim nws qhov kev ua tau zoo ntawm kev ua haujlwm siab induction, nws yuav ua rau kom cov lus teb ntawm cov teeb liab ntau zaus proportionally. Moist fatty los yog ntsev, xws li qhob cij, cheese, hnyuv ntxwm, thiab lwm yam muaj tib yam conductivity li hlau. Hauv qhov no, txhawm rau tiv thaiv lub kaw lus los ntawm kev muab cov cim tsis tseeb, cov teeb liab them nyiaj yuav tsum tau hloov kho kom txo tau qhov kev xav tau.
Hlau detector muaj nuj nqi los faib:
1) Tag nrho cov hlau ntes: Nws tuaj yeem ntes tag nrho cov hlau xws li hlau, stainless hlau, tooj liab, txhuas, thiab lwm yam. Qhov kev kuaj xyuas qhov tseeb thiab rhiab heev yog qhov siab, ruaj khov thiab txhim khu kev qha.
2) ferrous hlau ntes: Nws tsuas tuaj yeem ntes ferrous hlau, feem ntau hu ua rab koob ntes. Kev txheeb xyuas qhov tseeb thiab rhiab heev yog qhov tsawg, thiab nws yooj yim los cuam tshuam.
3) Aluminium foil hlau ntes: Nws tsuas tuaj yeem ntes cov hlau ferrous, tab sis thaum kuaj xyuas cov khoom nrog aluminium foil ntim, nws qhov kev tshawb pom qhov tseeb thiab rhiab heev yog tseem siab.
Nws yog tsim los ntawm cov cuab yeej siv siab heev, thiab nws muaj cov yam ntxwv ntawm kev tshawb pom dav, qhov tseeb qhov chaw, muaj zog daws teeb meem thiab ua haujlwm yooj yim. Cov khoom siv hlau feem ntau yog siv los kuaj xyuas thiab txheeb xyuas cov khoom hlau faus hauv av. Ntxiv rau nws daim ntawv thov hauv Is Taws Nem, nws kuj tau siv dav hauv: kev tshuaj xyuas kev ruaj ntseg, archaeology, prospecting, nrhiav cov khoom seem. Thiab
Hais tias "hlau detector" yog tus pab zoo rau kev rov ua dua tshiab.
Underground hlau ntes siv lub suab tswb thiab ntsuas ntsuas. Qhov kev tshawb pom qhov tob muaj kev sib raug zoo nrog thaj tsam, cov duab thiab qhov hnyav ntawm cov hlau yuav raug kuaj pom. Feem ntau hais lus, thaj tsam loj dua, tus lej ntau dua, thiab ntau dua qhov sib txuas kom pom qhov tob; Hloov pauv, qhov me me ntawm thaj chaw, tus lej tsawg dua, thiab qhov me dua qhov sib thooj qhov tob. Qhov siab tshaj plaws nrhiav kom pom qhov tob uas teev nyob rau hauv cov lus hauv qab no yog qhov tshwm sim ntawm qhov tseeb ntsuas los ntawm kev kos ib 60cm * 60cm * 0.5cm txhuas phaj hauv cov av qhuav raws li kev lag luam tus qauv ntawm cov khoom
Lub luag haujlwm tseem ceeb
Nruab nrog cov kab sib npaug hauv av, uas tuaj yeem tshem tawm qhov cuam tshuam ntawm "mineralization cov tshuaj tiv thaiv", zoo heev txhim kho qhov tob thiab qhov tseeb ntawm kev tshawb pom zoo;
Nws muaj cov haujlwm ntawm kev paub qhov txawv ntawm cov hlau ferrous thiab cov hlau tsis muaj hlau;
Siv cov kev ua haujlwm ntse;
Ntim nrog cov khoom muaj zog ABC, lub teeb hauv qhov hnyav thiab ntev hauv lub neej;
Cov suab hlau tuaj yeem txheeb xyuas los ntawm lub mloog pob ntseg.
Cov hlau yog faus rau hauv av thiab pom los ntawm cov av tuab, uas yuav tsum raug cuam tshuam los ntawm cov qauv geological. Muaj ntau yam minerals nyob rau hauv lub strata, thiab lawv kuj yuav tsim cov teeb liab rau kev kuaj hlau. Cov cim qhia ntawm cov zaub mov txaus yuav npog cov cim ntawm cov hlau thiab ua rau pom tsis tseeb. Cov neeg uas tau siv cov cuab yeej siv hlau qub qub muaj qhov kev paub no. Raws li qhov kev sojntsuam mus txog mounds, pob zeb, thiab cib, lub tswb yuav nrov. Qhov tshwm sim no hu ua "mineralization cov tshuaj tiv thaiv." Vim li no, cov cuab yeej siv hlau qub qub tuaj yeem ntes cov hlau hauv cov av ntiav, thiab tsis muaj zog rau cov hom phiaj hlau faus tob hauv av. Inugami underground hlau ntes tau nruab nrog cov txheej txheem hauv av siab, uas tuaj yeem tshem tawm qhov cuam tshuam ntawm "mineralization cov tshuaj tiv thaiv", zoo heev txhim kho qhov kev tshawb pom qhov tob thiab cov txiaj ntsig ntawm qhov ntsuas.
