Kuti tipeze zotsatira zabwino kwambiri, makina opanga makina amafunikira zigawo zingapo kuti zizigwira ntchito limodzi mosalakwitsa. Masensa am'malo, chinthu chocheperako koma chofunikira pakupanga makina opanga mafakitale, ndi nkhani ya nkhaniyi. Masensa omwe ali m'mafakitale opanga ndi kukonza amaonetsetsa kuti ntchito zofunika zimakwaniritsidwa monga momwe anakonzera, zomwe zimathandiza kuyang'anira ndi kuyang'anira njira zopangira. kusapezeka. Mavavu a pneumatic ali ndi ntchito zosiyanasiyana chifukwa amatha kutumiza ma siginecha kumakina owauza kuti achite zomwe zidakonzedweratu pomwe chandamale chili mkati mwa mtunda wokhazikitsidwa ndi sensa yamalo.

Sensor yamalo imapereka chizindikiro chouza makinawo kuti asiye kuchita zomwe zidakonzedweratu kapena kusinthana ndi ntchito ina pomwe chandamale chichoka pa sensor yamalo. Ngakhale chandamale chikhoza kukhala chilichonse, nkhaniyi ingoyang'ana zitsulo zachitsulo ndi njira "zambiri" zopezera kuti zikhale zosavuta. Kusintha kwa malire a makina, masensa oyandikira olowera, masinthidwe a malire a masika, ndi masinthidwe oletsa ndi ena mwaukadaulo uwu. Kumvetsetsa chilankhulo chomwe chimagwiritsidwa ntchito ndi ambiri opanga masensa ndizothandiza musanayang'ane mitundu yambiri ya masensa amtundu.

• Zomverera zosiyanasiyana: kulekanitsa pakati pa nkhope yomvera ndi chandamale chotsegula

• Hysteresis: mtunda pakati pa malo otulutsira ndi malo osinthira kusintha

• Kubwerezanso: Kutha kwa moyo wa masinthidwe kuti azindikire chandamale chomwechi mumtundu womwewo.

• Nthawi yoyankhira: nthawi yapakati pa kuzindikira chandamale ndi kupanga ma siginecha.

malire kusintha kuti ndi makina

Zipangizo zamagetsi zomwe zimatchedwa mechanical limit switches zimagwiritsa ntchito kukhudzana mwachindunji ndi chandamale kuti zizindikire kumene chandamaleyo ali. Amatha kuthandizira katundu wamakono ndikugwira ntchito popanda gwero la mphamvu. Masiwichi amakina samasamala za polarity kapena mphamvu yamagetsi chifukwa amagwiritsa ntchito zolumikizira zouma, zomwe zimapangitsa kuti zisagwirizane ndi zolakwika zosiyanasiyana zamagetsi monga phokoso lamagetsi, kusokoneza mawayilesi, kutayikira, komanso kutsika kwamagetsi. Mkono wa lever, batani, thupi, maziko, mutu, zolumikizirana, ma terminals, ndi zinthu zina zosuntha za masiwichi awa nthawi zambiri zimafunikira kukonza. Zosintha zamakina a Votto zitha kukhala zosabwerezabwereza chifukwa zimalumikizana mwachindunji ndi chandamale. Cholinga chokhacho komanso mkono wa lever ukhoza kuvala pokhudzana ndi thupi. Palinso malo opanda chitetezo omwe amatha kuchita dzimbiri, fumbi, ndi chinyezi. Chifukwa cha vutoli, madera owopsa ovomerezeka ndi osindikizidwa osindikizidwa nthawi zambiri amabwera pamtengo wokwera.

Chepetsani kusintha kwa masika

Kusintha kwa malire a kasupe ndi chida cha electromechanical chomwe chimagwiritsa ntchito maginito kukopa kuti mudziwe malo omwe maginito akupita. Tizitsulo tating'ono tating'ono tiwiri totsekeredwa mu chubu lagalasi tili mkati mwa switch. "Chinthu cha bango" ndi chomwe ichi chiri. Chifukwa cha mphamvu ya maginito, chinthu cha bango chimayankha ku zolinga za maginito poyambitsa. Popeza safuna kulumikizana mwachindunji ndi chandamale kuti agwire ntchito, masinthidwe amakasupe amapereka zabwino zonse zamakina osinthira ndikupewa zovuta zovala.

Zolinga zabwinobwino za ferrous sizingagwiritsidwe ntchito posintha malire a masika; Zolinga za maginito ndizofunikira. Kusintha kwa bango ndi kosadalirika chifukwa bango, chubu lagalasi, ndi tizitsulo tating'ono tachitsulo timatopa ndi kupindika. Kuthamanga kwapang'onopang'ono kungayambitse kulankhulana kwa zolumikizana ndi ma siginecha olakwika kuchokera ku bango pakagwedezeka kwambiri.

Masensa a Inductive Proximity

Chida cholimba chamagetsi chotchedwa inductive proximity sensor chimagwiritsa ntchito kusintha kwa mphamvu ya chinthu chachitsulo kuti chidziwe komwe chiri. Kukhudza thupi sikofunikira, ndipo palibe magawo osuntha kuti apanikizidwe, kutha, kapena kuwonongeka, zomwe zimachepetsa kukonza. Komanso imalimbana ndi fumbi ndi zonyansa chifukwa ilibe ziwalo zoyenda. Ma inductive proximity sensors amatha kusinthika pamagwiritsidwe osiyanasiyana ndipo amapezeka m'miyeso ndi mapangidwe angapo. Masensa oyandikira ochititsa chidwi sangathe kupirira katundu wamakono ndipo amafunikira gwero lamphamvu lakunja (magetsi) kuti agwire ntchito. Athanso kukhala pachiwopsezo cha kutsika kwamagetsi, mafunde akutayikira, kusokoneza ma radio frequency, ndi phokoso lamagetsi. Kusinthasintha kwa kutentha kwambiri ndi kulowa kwa chinyezi nthawi zina kumakhala koyipa kwa masensa am'mimba olowera.

malire malire kusintha

Pogwiritsa ntchito ukadaulo wapadera wosakanizidwa, zosintha zochepetsera zimatha kupeza zigoli zachitsulo kudzera m'magawo amagetsi. Leverless limit switches ndi yodalirika kwambiri pazovuta komanso kugwiritsidwa ntchito kwanthawi yayitali. Popeza palibe chifukwa chokhudza thupi kapena mphamvu yakunja, katundu wamkulu wamakono ndi zotheka ndipo palibe chomwe chingatseke, kupindika, kuphwanya, kapena kugaya. Mofanana ndi masiwichi amakina, samatha kumva phokoso lamagetsi, kusokoneza ma frequency a wailesi, mafunde otuluka, ndi kutsika kwamagetsi. Iwo salinso polarity- kapena voltage-sensitive. Fumbi, chinyontho, chinyontho, kukhudza thupi, ndi zowononga zambiri kapena mankhwala alibe mphamvu pakusintha malire. Mitundu yambiri imakhala ndi kutentha kwakukulu kogwira ntchito ndipo ndi yotetezeka. Kusintha kwa malire kwa leverless ndikwabwino kwa mapulogalamu omwe amafunikira kutsekeka kwamadzi ndi kuphulika chifukwa cha kulumikizana kwake kosindikizidwa ndi mpanda wolimba wachitsulo.

Masensa am'maudindo ndi ofunikira kwambiri pakupanga makina amakampani. Pali matekinoloje angapo amsika pamsika, iliyonse ili ndi mawonekedwe ake. Kuti mupeze magwiridwe antchito ofunikira komanso kudalirika, chisamaliro chiyenera kupangidwa posankha mtundu woyenera wa sensa kuti mugwiritse ntchito.
