Ukuze kuveliswe iziphumo ezikumgangatho ophezulu, iinkqubo zoshishino ezizenzekelayo zifuna amacandelo amaninzi ahlukeneyo ukuba asebenze ngokugqibeleleyo kunye. Abenzi boluvo besikhundla, into ethobekileyo kodwa ebalulekileyo kwimizi-mveliso ezenzekelayo, ingumxholo weli nqaku. Izikhundla zoluvo kwiindawo zokuvelisa kunye nokucubungula ziqinisekisa ukuba imisebenzi ebalulekileyo ifezekiswa njengoko kucwangcisiwe, enceda ekubekweni esweni nasekulawuleni iinkqubo zokuvelisa. Ukuchaneka ngakumbi, umsebenzi wabo oyintloko kukufumana "iithagethi" okanye ukuhambisa izinto kunye nokuxela ngobukho babo okanye ukungabikho. Iivalvu ze-pneumatic zineendlela ezahlukeneyo zokusetyenziswa kuba zinokuthumela imiqondiso kwisistim eyixelela ukuba yenze isenzo esicwangcisiweyo xa ithagethi ingaphakathi komgama obekiweyo wesivamvo sendawo.

Uluvo lwendawo lunikezela ngophawu oluxelela inkqubo ukuba iyeke ukwenza loo msebenzi ucwangciswe kwangaphambili okanye utshintshele komnye umsebenzi xa ithagethi isuka kude kwimo yoluvo. Nangona ithagethi inokuba yiyo nantoni na, eli nqaku liza kuvavanya kuphela iithagethi zentsimbi kunye neendlela "eziqhelekileyo" zokuzifumana ngenxa yokulula. Iiswitshi zomda womatshini, abenzi boluvo abasondeleleneyo, ukutshintshwa komda wentwasahlobo, kunye nokutshintsha umda zezinye zezi teknoloji. Ukuqonda ulwimi oluqhelekileyo olusetyenziswa luninzi lwabavelisi beenzwa luncedo ngaphambi kokuphonononga iindidi ezininzi ze-position sensors.

• Uluhlu lweemvakalelo: ukwahlukana phakathi kobuso obuvayo kunye nethagethi yokutshintsha-isebenze

• I-Hysteresis: umgama phakathi kwendawo yokukhulula kunye nendawo yokuqalisa yokutshintsha

• Ukuphinda-phinda: Umthamo wobomi botshintsho ukuze uchonge ngokuthe rhoqo into ekujoliswe kuyo ngaphakathi kuluhlu olufanayo.

• Ixesha lokuphendula: isithuba phakathi kokufunyaniswa okujoliswe kuko kunye nokuveliswa komqondiso wemveliso.

umda switch ukuba oomatshini

Izixhobo ze-electromechanical ezibizwa ngokuba zii-mechanical limit switch zisebenzisa ukudibana ngokuthe ngqo komzimba noko kujoliswe kuko ukuva indawo ekujoliswe kuyo. Banokuxhasa imithwalo ephezulu yangoku kwaye basebenze ngaphandle komthombo wamandla. Izitshixo zoomatshini azikhathali malunga nepolarity okanye amandla ombane kuba zisebenzisa unxibelelwano olomileyo, nto leyo ezenza zikwazi ukumelana neziphene zombane ezahlukeneyo njengengxolo yombane, uphazamiseko lwamaza kanomathotholo, ukuvuza kwangoku, kunye nokuhla kwamandla ombane. Ingalo ye-lever, iqhosha, umzimba, isiseko, intloko, abafowunelwa, ii-terminals, kunye nezinye izinto ezihambayo zolu tshintsho zifuna ukugcinwa rhoqo. Iiswitshi zomda womatshini weVotto zinokuba nokuphindaphinda okulambathayo kuba zidibana ngqo noko kujoliswe kuko. Ithagethi ngokwayo kunye nengalo ye-lever inokunxitywa ngokudibana ngokomzimba. Kukwakho nemingxuma engakhuselekanga esengozini yokubola, uthuli nokufuma. Ngenxa yale ngxaki, iindawo ezinobungozi eziqinisekisiweyo kunye noqhagamshelwano olutywiniweyo luhlala luza ngexabiso eliphezulu.

Ukunciphisa ukutshintshwa kwentwasahlobo

Ukutshintsha umda wasentwasahlobo sisixhobo se-electromechanical esisebenzisa umtsalane wamagnetic ukujonga indawo ekujoliswe kuyo ngumagnetic. Iiprong ezimbini ezincinci zetsimbi ezifakwe kwityhubhu yeglasi zibekwe ngaphakathi kwesitshixo. "Ingcongolo" yintoni le. Ngenxa yobuntununtunu bemagnethi, into yengcongolo iphendula kwiithagethi zemagnethi ngokusebenza. Kuba ayifuni unxibelelwano oluthe ngqo kunye nethagethi ukuze isebenze, izitshixo zomda wentwasahlobo zibonelela ngazo zonke izibonelelo zokutshintsha koomatshini ngelixa uphepha ubunzima bokunxiba.

Iithagethi eziqhelekileyo ze-ferrous azinakusetyenziswa ngokutshintsha umda wasentwasahlobo; iithagethi zemagneti ziyimfuneko. Umtshini wengcongolo awuthembekanga ngenxa yokuba i-elementi yengcongolo, ityhubhu yeglasi, kunye ne-prongs encinci yesinyithi iyadinwa kukugoba. Uxinzelelo loqhagamshelwano olusezantsi lunokukhokelela ekuncokoleni kwabafowunelwa kunye nemiqondiso eyimpazamo evela kwingcongolo kwiimeko zokungcangcazela okuphezulu.

IiSensors for Inductive Proximity

Isixhobo sombane esikwimeko eqinileyo esibizwa ngokuba sisivamvo sokusondelelana sisebenzisa utshintsho kumhlaba wamandla wento eyintsimbi ukumisela ukuba iphi na. Ukuchukumisa umzimba akufuneki, kwaye akukho zixhobo ezihambayo kwi-jam, ukuguga, okanye umonakalo, othoba ukugcinwa. Iyakwazi ukumelana nothuli nokungcola kuba ayinazo iindawo ezihambayo. I-inductive proximity sensors zilungelelaniswa kakhulu kuluhlu lwezicelo kwaye ziyafumaneka kwinani lobungakanani kunye noyilo. I-inductive proximity sensors ayikwazi ukunyamezela imithwalo yangoku ephezulu kwaye idinga umthombo wamandla wangaphandle (umbane) ukuze usebenze. Basenokuba sesichengeni sokuhla kwamandla ombane, imisinga yokuvuza, uphazamiseko lwamaza kanomathotholo, kunye nengxolo yombane. Ukutshintsha kobushushu obugqithisileyo kunye nokungena kokufuma ngamanye amaxesha kunokuba kubi kwi-inductive proximity sensors.

umda umda switch

Ngokusebenzisa itekhnoloji ekhethekileyo ye-hybrid, umda wokutshintshela umda unokukhangela iithagethi ze-ferrous ngokusebenzisa imimandla ye-electromagnetic. I-Leverless limit switchs ixhomekeke ngokumangalisayo kwiimeko ezinzima kunye nokusetyenziswa kwexesha elide. Ekubeni kungekho mfuneko yokubamba ngokoqobo okanye amandla angaphandle, imithwalo emikhulu yangoku inokwenzeka kwaye akukho nto inokujongisa, ukugoba, ukuqhekeza, okanye ukucola. Ngokufana nokutshintsha koomatshini, abakwazi ukumelana nengxolo yombane, ukuphazamiseka kwamaza kanomathotholo, imisinga yokuvuza, kunye nokuhla kwamandla ombane. Kananjalo azikho polarity- okanye i-voltage-sensitive. Uthuli, ubumdaka, ukufuma, ukubanjwa komzimba, kunye noninzi lwezinto ezityiwayo okanye iikhemikhali azinampembelelo ekutshintsheni umda womda. Uninzi lweentlobo lunoluhlu olubanzi lobushushu obusebenzayo kwaye zikhuselekile ngaphakathi. Umda wokutshintshwa kwe-leverless uphelele kwizicelo ezifuna ukungangeni kwamanzi kunye nobungqina bokuqhuma ngenxa yokudibanisa okuvaliweyo kunye nentsimbi eqinile.

Abenzi boluvo besikhundla babalulekile kumatshini weenkqubo ezizenzekelayo. Kukho ubuninzi betekhnoloji yesivamvo kwimarike, nganye ineseti eyahlukileyo yeempawu zokusebenza. Ukuze kuzuzwe ukusebenza okufunekayo kunye nokuthembeka, kufuneka kunyamekelwe ukukhetha uhlobo olufanelekileyo lwenzwa kwisicelo.
