Ivalvu yeTWS evela eTianjin, eTshayina

Amagama angundoqo:Iswitshi yomda yoomatshini; Iswitshi yomda wokusondela

1. Utshintsho lomlinganiselo woomatshini

Ngokwesiqhelo, olu hlobo lweswitshi lusetyenziselwa ukunciphisa indawo okanye ukujijeka kwentshukumo yoomatshini, ukuze oomatshini abahambayo bakwazi ukuma ngokuzenzekelayo, umva intshukumo, intshukumo yesantya esiguquguqukayo okanye intshukumo ejijekayo ezenzekelayo ngokwendawo ethile okanye ukujijeka. Iquka intloko yokusebenza, inkqubo yoqhagamshelwano kunye nendlu. Yahlulwe yaba yintshukumo ethe ngqo (iqhosha), ukuqengqeleka (ukujikelezisa), isenzo esincinci kunye nokudibanisa.

Utshintsho lomlinganiselo olusebenza ngqo: umgaqo wesenzo ufana noweqhosha, umahluko kukuba elinye lisebenza ngesandla, kwaye elinye lingqubana nebhampa yenxalenye ehambayo. Xa ibhloko yokuchaphazela kwinxalenye ehambayo yangaphandle icinezela iqhosha ukuze ishukume, xa inxalenye ehambayo ishiya, unxibelelwano luqala ngokutsha ngokuzenzekelayo phantsi kwesenzo sentwasahlobo.

Iswitshi yokumisela umda wokuqengqeleka: Xa i-stop iron (i-collision block) yomatshini oshukumayo icinezelwe kwi-roller yeswitshi yokumisela umda, intonga yokudlulisela ijikeleza kunye ne-rolling shaft, ukuze i-cam ityhale i-impact block, kwaye xa i-impact block ifika kwindawo ethile, ityhala intshukumo encinci. Iswitshi isebenza ngokukhawuleza. Xa i-stop iron kwi-roller isusiwe, i-return spring iphinda iqalise iswitshi yokuhamba. Le yi-single-wheel automatic recovery limit switch. Kwaye i-rotary type travel switch ejikelezayo yamavili amabini ayinakubuyela ngokuzenzekelayo, kwaye xa ixhomekeke kumatshini oshukumayo ukuba ihambe kwicala elichaseneyo, i-iron stopper ingqubana nenye i-roller ukuze iyibuyisele.

I-micro switch yi-snap switch eqhutywa luxinzelelo. Umgaqo wayo osebenzayo kukuba amandla angaphandle oomatshini asebenze kwi-action reed nge-transmission element (cofa i-pin, iqhosha, i-lever, i-roller, njl.njl.), kwaye emva kokuba amandla eqokelelwe kwindawo ebalulekileyo, kwenziwa isenzo esikhawulezileyo, ukuze i-moving contact ekupheleni kwe-action reed Ingongoma kunye ne-fixed contact ziqhagamshelwe okanye ziqhawulwe ngokukhawuleza. Xa amandla kwi-transmission element esusiwe, i-action reed ivelisa i-reverse action force, kwaye xa i-reverse stroke ye-transmission element ifikelela kwindawo ebalulekileyo ye-action ye-reed, isenzo esingasemva sigqitywa ngoko nangoko. Umgama woqhagamshelwano lwe-micro switch mncinci, i-action stroke imfutshane, amandla okucinezela mancinci, kwaye i-on-off ikhawuleza. Isantya sesenzo se-moving contact yayo asinanto yakwenza nesantya sesenzo se-transmission element. Uhlobo olusisiseko lwe-micro switch luhlobo lwe-push pin, olunokufumaneka kwi-button short stroke type, button large stroke type, button extra large stroke type, roller button type, lever roller type, short arm type, long arm type njl.njl.

Iswitshi yomda wevalvu yoomatshini idla ngokusebenzisa iswitshi encinci yoqhagamshelwano olungasebenziyo, kwaye ifom yeswitshi inokwahlulwa ibe: i-single pole double throw SPDT, i-single pole single throw SPST, i-double pole double throw DPDT.

2. Utshintsho lomda wokusondela

Iswitshi yokusondela, eyaziwa ngokuba yiswitshi yokuhamba engadibaniyo, ayinakuthatha indawo yeswitshi yokuhamba ngokudibanisa ukuze igqibezele ulawulo lokuhamba kunye nokukhusela umda, kodwa ikwasetyenziselwa ukubala okuphezulu, ukulinganisa isantya, ulawulo lwenqanaba lolwelo, ukufumanisa ubungakanani benxalenye, uqhagamshelo oluzenzekelayo lweenkqubo zokucubungula. Kuba ineempawu ze-trigger engadibaniyo, isantya sesenzo esikhawulezayo, isenzo ngaphakathi kwemigama eyahlukeneyo yokufumanisa, isignali ezinzileyo nengenamaza, umsebenzi ozinzileyo nothembekileyo, ubomi obude, ukuchaneka kokubeka okuphindaphindwayo okuphezulu kunye nokuzivumelanisa neemeko zokusebenza ezinzima, njl.njl., ngoko ke isetyenziswa kakhulu kwimveliso yemizi-mveliso efana nezixhobo zoomatshini, amalaphu, ushicilelo, kunye neeplastiki.

Iiswitshi zokusondela zahlulwe ngokomgaqo wokusebenza: ikakhulu uhlobo lwe-oscillation olusebenzisa i-frequency ephezulu, uhlobo lwe-Hall, uhlobo lwe-ultrasonic, uhlobo lwe-capacitive, uhlobo lwe-differential coil, uhlobo lwe-magnet oluhlala luhleli, njl. Uhlobo lwe-magnet oluhlala luhleli: Lusebenzisa amandla okufunxa e-magnet ehlala luhleli ukuqhuba i-reed switch ukuze ikhuphe isignali.

Uhlobo lwekhoyili eyahlukileyo: Isebenzisa i-eddy current kunye notshintsho lwentsimi yemagnethi eveliswayo xa into efunyenweyo isondela, kwaye isebenza ngokwahlukana phakathi kwekhoyili yokufumanisa kunye nekhoyili yokuthelekisa. Iswitshi yokusondelana kwe-Capacitive: Yenziwe ikakhulu yi-oscillator ye-capacitive kunye nesekethe ye-elektroniki. I-capacitance yayo ikwi-interface yokubona. Xa into isondela, iya kushukuma ngenxa yokutshintsha ixabiso layo le-coupling capacitance, ngaloo ndlela ivelisa i-oscillation okanye imise i-oscillation ukuvelisa isignali yokuphuma. utshintsho oluninzi nangakumbi. Iswitshi yokusondelana kwe-Hall: Isebenza ngokuguqula imiqondiso yemagnethi ibe yimveliso yesignali yombane, kwaye imveliso yayo inomsebenzi wokugcina imemori. Isixhobo sangaphakathi se-magnetic sensitive sivakalelwa kuphela yintsimi yemagnethi ethe nkqo kubuso bokugqibela be-sensor. Xa i-magnetic pole S ijongene neswitshi yokusondelana, imveliso yeswitshi yokusondelana inomtsintsi olungileyo, kwaye imveliso iphezulu. Ukuba i-magnetic pole N ijongene neswitshi yokusondelana, imveliso iphantsi.

Iswitshi yokusondela kwe-Ultrasonic: Iquka ikakhulu izinzwa ze-ceramic ze-piezoelectric, izixhobo ze-elektroniki zokudlulisa amaza e-ultrasonic kunye nokwamkela amaza abonakalisiweyo, kunye neeswitshi ze-bridge ezilawulwa yinkqubo zokulungisa uluhlu lokufumanisa. Ifanelekile ukufumanisa izinto ezingenakuchukunyiswa okanye ezingenakuchukunyiswa. Umsebenzi wayo wolawulo awuphazanyiswa zizinto ezifana nesandi, umbane, kunye nokukhanya. Ithagethi yokufumanisa inokuba yinto ekwimeko eqinileyo, engamanzi okanye engumgubo, lo gama nje inokubonakalisa amaza e-ultrasonic.

Iswitshi yokusondela kwe-oscillation ephindaphindayo: Iqaliswa yintsimbi, equlunqwe ikakhulu ngamacandelo amathathu: i-oscillator ephindaphindayo, isekethe edibeneyo okanye i-transistor amplifier kunye nesixhobo sokuphuma. Umgaqo wayo osebenzayo ngulo: i-coil ye-oscillator ivelisa intsimi yemagnethi etshintshanayo kumphezulu osebenzayo weswitshi, xa into yesinyithi isondela kumphezulu osebenzayo, umsinga we-eddy owenziwe ngaphakathi kwento yesinyithi uya kutsala amandla e-oscillator, nto leyo ebangela ukuba i-oscillator iyeke ukungcangcazela. Imiqondiso emibini ye-oscillation kunye ne-vibration stop ye-oscillator iguqulwa ibe yimiqondiso ye-binary switching emva kokuba ibunjwe kwaye yandiswa, kwaye imiqondiso yokulawula i-switching iyaphuma.

Iswitshi yevalvu yokungenisa imagnethi ngokubanzi isebenzisa iswitshi yokusondela kwe-electromagnetic induction ye-passive contact, kwaye ifom yeswitshi inokwahlulwa ibe: i-single pole double throw SPDT, i-single pole single throw SPSr, kodwa akukho double pole double throw DPDT. I-magnetic induction ngokubanzi yahlulwe yaba ziintambo ezi-2 ezivulwa okanye ezivaliweyo, kwaye intambo ezi-3 zifana ne-single-pole double-throw SPDT, ngaphandle kwesiqhelo evulwa kwaye ivaliwe.
