Noise injodzi yakajairika pabasa mumafekitari ekugadzira chikafu.Kubva pamapaneru anozunguza kusvika kumakanika rotor, stator, mafeni, maconveyor, pombi, compressors, palletitisers uye forogo inosimudza.Pamusoro pezvo, kumwe kuvhiringika kuri pachena kusinga nyatso kuoneka kunogona kukanganisa mashandiro ekuona simbi kwakanyanya uye cheki yekuyera michina.Iyo inonyanya kufuratirwa kuve pasi / pasi zvishwe uye magetsi emagetsi madhiraivha.
Jason Lu, Technical Applications Support paFanchi Technology, anoongorora chikonzero uye mhedzisiro yekuvhiringidza uku uye matanho anogona kuitwa kuderedza kukanganiswa kweruzha.
Zvinhu zvakawanda zvinotarisa kunzwisiswa kwetioreti kweametal detector.Pakati pavo pane aperture saizi (iyo diki iyo aperture, diki chidimbu chesimbi chinogona kuwonekwa), rudzi rwesimbi, chigadzirwa mhedzisiro, uye kutaridzika kwechigadzirwa uye kusvibiswa sezvainopfuura nemu detector.Nekudaro, mamiriro ezvakatipoteredza, akadai sekuvhiringidzwa kwemagetsi emhepo - static, redhiyo kana pasi zvishwe - vibration, semuenzaniso kufamba simbi, uye tembiricha kushanduka, senge ovheni kana kutonhora tunnel, zvinogona kukanganisa kushanda.
Akasarudzika maficha akaita seNoise Immunity Structure uye mafirita edhijitari ayo anowanikwa pamakambani edhijitari simbi madhijitari anogona kudzvanyirira imwe yeiyi ruzha rwekukanganisa, izvo zvingangoda kudzikisira mazinga ekunzwa.
Iwo makuru masosi ekukanganiswa kwemagetsi uye kukanganiswa kweredhiyo kunosanganisira madhiraivha emagetsi - semuenzaniso madhiraivha madhiraivha uye servo mota, tambo dzemotor dzisina kuchengetedzwa nemazvo, maredhiyo maviri, anosanganisira walkie talkies, pasi zvishwe, magetsi madhiraivha uye static discharge.
Ground loop mhinduro
Dambudziko rakanyanya kupararira neFanchi mainjiniya vanosangana naro rinozova nyaya yakajairika mumafekitori ezvekudya.Kunyanya pamagumo-kusvika-kumagumo ekugadzirisa mitsara anosanganisira marobhoti, mabhegi, kuyerera kwekuputira uye maconveyors.Mhedzisiro yekukanganiswa kwemagetsi inogona kukanganisa mashandiro ematare edhijitari zvichikonzera kuwonekwa kwenhema, kurambwa kwenhema, uye nekudaro kuwedzera njodzi yekuchengetedza chikafu.
"Michina yekurongedza yakadai seyekuyerera wrappers uye conveyor mabhandi inowanzova iyo honzeri huru yepasi loop nyaya nekuda kwekusakara kana kusununguka kwekugadzirisa uye rollers" anodaro Jason.
Ground loop mhinduro inoitika kana chero nhengo dzesimbi dziri padyo ne detector dzichibatana kuti dziite conductive loop, semuenzaniso roller isingaite iyo isina kuvharirwa zvakanaka kune rimwe divi refuremu inonyora Jason.Anotsanangura kuti: “Mafomu e loop anoita kuti magetsi anyandurwa afambe.Izvi zvinogona kukonzera ruzha rwunokanganisa chiratidzo chesimbi uye zvinogona kukonzera nyaya dzekugadzirisa, sekuramba kwechigadzirwa chenhema ”.
Mafungu eredhiyo
Kubatwa kwe ametal detectorkukanganiswa kwemagineti kana kwemagetsi kunoenderana zvakanyanya nekunzwa kwayo uye yekuona bandwidth.Kana imwe detector yesimbi ichitumira frequency yakafanana kune imwe munzvimbo yefekitari yakabatikana, inokwanisa kuyambuka kurukurirano kana yaiswa padhuze.Kudzivirira kuti izvi zvisaitike, Fanchi inokurudzira kuti zvionere simbi zvipatsanurwe zvingangoita mamita mana kubva padivi, kana kudzedzeresa simbi inoongorora mafambiro kuitira kuti isanyatsoenderana.
Marefu uye epakati wave transmitters - akadai sewalkie talkies - haawanzo kukonzera matambudziko.Kupa ivo vasina kukwizwa zvakanyanya kana kushandiswa padyo nepedyo nesimbi detector coil inogamuchira.Kuti uchengetedze, chengeta walkie talkies ichishanda pawatts matatu kana pasi.
Digital kutaurirana zvishandiso, semuenzaniso mafoni akangwara, anoburitsa kunyange kushoma kwekukanganisa kweruzha, anodaro Jason."Zvinoenderana nekunzwa kwecoil unit uye zvakare padyo nemudziyo kune simbi detector.Asi nharembozha hadziwanzo pane imwechete bandwidth semidziyo yekugadzirisa.Saka inyaya shoma."
Static troubleshooting
Mhedzisiro EMI inogona kukanganisa kuita kwemichina yesimbi
Chero kufamba kudiki mukugadzirwa kwemichina yesimbi inocherekedza izvo zvinokonzeresa kuzunguzika kudiki kunogonawo kukonzeresa kurambwa kwenhema.Kuvakwa kwemagetsi akasimba kunowanzoitika pane giravhiti uye vertical metal yekuona maapplication kana pombi isina kuiswa ivhu nemazvo, anodaro Jason.
Kuwana dhizaini yesimbi pane mezzanine pasi kunogona kugadzira zvinogona kuitika.Zvinotonyanya kuwedzera mechanic ruzha infractions, kunyanya kubva kune chutes, hoppers uye conveyors."Metal detectors ayo akaiswa kune zvigadzirwa zvakanyorova kazhinji anotonyanya kutarisisa kurudzi urwu rwekudedera uye ruzha," anodaro Jason.
Kuti ive nechokwadi chekushanda kwakavimbika uye kudzivirira kudedera, zvese zvimiro zvekutsigira uye zvigadziriso zvekuramba zvinofanirwa kusungirirwa.Fanchi zvakare inodzivirira kushandisa anti-static bhandi zvinhu, sezvo izvi zvakare zvinogona kuderedza simbi detector kuita.
Kutsvaga kunobva dambudziko nekukurumidza uye nenzira kwayo kwakakosha, sezvo kupindira kunoramba kuripo pamatanho ekugadzirisa otomatiki kunogona kukonzera kukanganisa kwesevhisi.Fanchi inogona kuendesa sniffer unit kuti ikurumidze kuteedzera kwaibva EMI neRFI iri padyo.Senge antenna, iyo chena disc inoyera wavelengths uye inogona nekukasira kutsvaga kwainobva makwikwi emakwikwi.Neruzivo urwu, mainjiniya anogona kudzivirira, kudzvanya kana kushandura nzira yekubuda.
Fanchi inopawo sarudzo yekusimudzira kune yakakwira voltage oscillator.Kune zvigadziriso zvekugadzira zvine ruzha, zvinosanganisira zvidyarwa zvine otomatiki, iyi mhinduro inoita iyo Fanchi simbi detector ndiyo ine ruzha sosi.
Mushandisi-ane hushamwari
Fanchi maficha senge otomatiki imwe pass kudzidza uye calibration inogona kuunza chaiyo sisitimu yekumisikidza mukati memasekondi uye kubvisa zvikanganiso zvevanhu.Pamusoro pezvo, yakavakirwa-mukati ruzha yekudzivirira chimiro - inosanganisirwa seyakajairwa pane ese eFanchi dijitari simbi inoongorora, inogona kudzikisa zvakanyanya mhedzisiro yekunze ruzha rwemagetsi, zvakare zvichikonzera kushomeka kwechigadzirwa chenhema.
Jason anogumisa kuti: “Hazvibviri kubvisa zvachose kukanganiswa kweruzha munzvimbo dzekugadzira.Asi, nekutora chenjedzo idzi uye kutsvaga hutungamiriri hwenyanzvi, mainjiniya edu anogona kuderedza zvakanyanya mhinduro yeEMI uye kuona kuti simbi yekuona uye kunzwa haina kukanganisa. "
