I-TWS Valve evela eTianjin, eChina

Amagama Abalulekile:Ukushintshwa komkhawulo wemishini;I-Proximity limit switch

1. Iswishi yomkhawulo wemishini

Ngokuvamile, lolu hlobo lokushintsha lusetshenziselwa ukukhawulela isikhundla noma ukushaywa kokunyakaza komshini, ukuze umshini ohambayo ukwazi ukuma ngokuzenzakalelayo, ukunyakaza okuhlehlayo, ukunyakaza kwesivinini esiguquguqukayo noma ukunyakaza okuzenzakalelayo okuphindaphindayo ngokusho kwesikhundla esithile noma ukushaywa.Iqukethe inhloko yokusebenza, isistimu yokuxhumana kanye nendlu.Ihlukaniswe ngesenzo esiqondile (inkinobho), ukugoqa (i-rotary), isenzo esincane kanye nenhlanganisela.

Iswishi yomkhawulo osebenza ngokuqondile: isimiso sesenzo sifana nesenkinobho, umehluko wukuthi eyodwa ibhalwe ngesandla, kanti enye ingqubuzana nebhampa yengxenye ehambayo.Lapho ibhulokhi yomthelela engxenyeni ehambayo yangaphandle icindezela inkinobho ukwenza ukuthintana kuhambe, lapho ingxenye ehambayo ihamba, othintana naye usetha kabusha ngokuzenzakalelayo ngaphansi kwesenzo sentwasahlobo.

I-Rolling limit switch: Uma i-stop iron (ibhulokhi yokushayisana) yomshini onyakazayo icindezelwa ku-roller ye-switch limit, induku yokudlulisela izungeza kanye ne-shaft ejikelezayo, ukuze ikhamera iphushe ibhulokhi yomthelela, nalapho ibhulokhi yomthelela. ishaya indawo ethile, iphusha ukunyakaza okuncane Iswishi isebenza ngokushesha.Lapho i-ayina yokumisa ku-roller isuswa, isiphethu sokubuya sisetha kabusha iswishi yokuhamba.Lena iswishi yomkhawulo wokutakula okuzenzakalelayo kwesondo elilodwa.Futhi inkinobho yokuhamba yohlobo lwe-rotary enamasondo amabili ayikwazi ukululama ngokuzenzakalelayo, futhi uma ithembela emshinini onyakazayo ukuthi ihambe iye kolunye uhlangothi, isivalo sensimbi sishayisana kwenye irola ukuze siyibuyisele.

I-micro switch iyi-snap switch eqhutshwa ukucindezela.Isimiso sayo sokusebenza siwukuthi amandla omshini wangaphandle asebenza emhlangeni wesenzo ngokusebenzisa isici sokudlulisa (iphinikhodi, inkinobho, i-lever, i-roller, njll.), futhi ngemva kokuba amandla eqoqwe endaweni ebalulekile, isenzo esisheshayo sikhiqizwa, ngakho-ke. ukuthi othintana naye onyakazayo ekugcineni kohlanga lwesenzo Iphuzu noxhumene naye ogxilile kuxhunywa ngokushesha noma kunqanyulwe.Lapho amandla esici sokudlulisela esuswa, umhlanga wesenzo ukhiqiza amandla esenzo ahlehlayo, futhi lapho ukuhlehla kwesici sokudlulisela sifinyelela iphuzu elibucayi lesenzo somhlanga, isenzo sokuhlehla siqedwa ngaso leso sikhathi.Ibanga lokuxhumana le-micro switch lincane, isenzo sifushane, amandla okucindezela mancane, futhi ukuvala kuyashesha.Isivinini sesenzo sothintana naye onyakazayo asihlangene nesivinini sesenzo sesici sokudlulisela.Uhlobo oluyisisekelo lwe-micro switch uhlobo lwephinikhodi, olungasuselwa kunkinobho yohlobo lwe-stroke olufushane, inkinobho yohlobo lwe-stroke enkulu, inkinobho yohlobo lwe-stroke olukhulu, uhlobo lwenkinobho ye-roller, uhlobo lwe-reed roller, uhlobo lwe-lever roller, uhlobo lwengalo emfushane, ingalo ende. uhlobo njll.

Umshini wokushintsha umkhawulo wevalvu ngokuvamile wamukela ukushintsha okuncane kokuthintana nokwenziwa, futhi ifomu lokushintsha lingahlukaniswa libe: I-SPDT yokuphonswa kabili kwepali eyodwa, i-SPST yokuphonsa okukodwa kwe-SPST, i-DPST yokuphonsa kabili kabili.

2. Iswishi yomkhawulo wokusondela

I-Proximity switch, eyaziwa nangokuthi i-non-contact travel switch, ayikwazi nje ukufaka esikhundleni iswishi yokuhamba nokuxhumana ukuze iqedele ukulawula ukuhamba nokuvikela umkhawulo, kodwa futhi isetshenziselwe ukubala okuphezulu, ukulinganisa isivinini, ukulawula izinga loketshezi, ukutholwa kosayizi wengxenye, uxhumano oluzenzakalelayo lwe ukucubungula izinqubo linda.Ngoba inezici ze-trigger engathinteki, isivinini sesenzo esisheshayo, isenzo ngaphakathi kwamabanga ahlukene okutholwa, isignali ezinzile nengenawo ukushaya kwenhliziyo, umsebenzi ozinzile nothembekile, impilo ende, ukunemba kokuphindaphinda okuphezulu kanye nokuvumelana nezimo zokusebenza ezinokhahlo, njll., ngakho-ke Isetshenziswa kakhulu ekukhiqizweni kwezimboni njengamathuluzi omshini, izindwangu, ukuphrinta, namapulasitiki.

Ukushintsha kwe-Proximity kuhlukaniswe ngokwesimiso sokusebenza: ikakhulukazi uhlobo lwe-high-frequency oscillation, uhlobo lwehholo, uhlobo lwe-ultrasonic, uhlobo lwe-capacitive, uhlobo lwekhoyili ehlukile, uhlobo lukazibuthe oluhlala njalo, njll. shayela iswishi yomhlanga ukuze ukhiphe isignali.

Uhlobo lwekhoyili oluhlukile: Isebenzisa i-eddy current kanye noshintsho lwezibuthe ezikhiqizwa lapho into etholiwe isondela, futhi isebenza ngomehluko phakathi kwekhoyili yokutholwa nekhoyili yokuqhathanisa.I-Capacitive proximity switch: Ikakhulukazi yakhiwe i-capacitive oscillator kanye nesekethe ye-elekthronikhi.Amandla ayo atholakala kusixhumi esibonakalayo senzwa.Uma into isondela, izonyakazisa ngenxa yokushintsha inani layo lokuhlanganisa amandla, ngaleyo ndlela ikhiqize ukuzungeza noma imise ukuzungeza ukuze ikhiqize isignali yokuphumayo.ushintsho olwengeziwe.I-Hall proximity switch: Isebenza ngokuguqula amasignali kazibuthe abe okukhipha isignali kagesi, futhi okukhiphayo kunomsebenzi wokugcina inkumbulo.Idivayisi ezwelayo kazibuthe yangaphakathi izwela kuphela endaweni kazibuthe perpendicular to the end face of the sensor.Uma isigxobo sikazibuthe S sibheke iswishi yokusondela, okukhiphayo kweswishi eseduze kunokweqa okuhle, futhi okukhiphayo kuphezulu.Uma isigxobo sikazibuthe N sibheke iswishi yokusondelana, okukhiphayo kuphansi.izinga.

I-Ultrasonic proximity switch: Iqukethe ikakhulukazi izinzwa zobumba ze-piezoelectric, izinto zikagesi zokudlulisa amagagasi e-ultrasonic nokwamukela amagagasi abonisiwe, namaswishi ebhuloho alawulwa uhlelo ukuze kulungiswe ububanzi bokuthola.Ilungele ukuthola izinto ezingakwazi ukuthintwa noma ezingakwazi ukuthintwa.Umsebenzi wayo wokulawula awuphazanyiswa izici ezinjengomsindo, ugesi, nokukhanya.Ithagethi yokuthola ingaba into esesimweni esiqinile, esiwuketshezi noma esiyimpushana, inqobo nje uma ingabonisa amaza e-ultrasonic.

I-high-frequency oscillation proximity switch: Ibangelwa insimbi, ikakhulukazi eyakhiwe izingxenye ezintathu: i-oscillator ephakeme kakhulu, isifunda esihlanganisiwe noma i-transistor amplifier kanye nedivayisi yokukhipha.Umgomo wayo wokusebenza uthi: ikhoyili ye-oscillator ikhiqiza inkambu kazibuthe eshintshanayo endaweni esebenzayo yokushintsha, lapho into yensimbi isondela endaweni esebenzayo, i-eddy current ekhiqizwa ngaphakathi kwensimbi izomunca amandla e-oscillator, okwenza i-oscillator ukuyeka ukudlidliza.Izimpawu ezimbili ze-oscillation kanye nokuma kokudlidliza kwe-oscillator ziguqulwa zibe amasignali okushintsha kanambambili ngemva kokubunjwa nokukhuliswa, futhi amasignali okulawula ukushintsha ayaphuma.

Iswishi yomkhawulo wevalvu wokungenisa kazibuthe ngokuvamile yamukela iswishi ye-electromagnetic induction proximity switch of the passiv, futhi ifomu lokushintsha lingahlukaniswa libe: I-SPDT yesigxobo esisodwa sokujikijela okuphindwe kabili, i-SPSr yokuphonswa kwepali eyodwa, kodwa ayikho i-DPDT yokuphonswa kabili kwepali ephindwe kabili.Ukungeniswa kukazibuthe kuvame ukuhlukaniswa ngocingo olu-2 oluvamise ukuvuleka noma oluvamise ukuvaleka, futhi intambo engu-3 ifana ne-SPDT yokuphonswa kabili kwesigxobo esisodwa, ngaphandle kokuvula nokuvalwa ngokuvamile.
