Mazwi Akakosha:Mechanical muganhu chinja; Proximity limit switch

1. Mechanical limit switch

Kazhinji, rudzi urwu rwekuchinja runoshandiswa kudzikamisa chinzvimbo kana sitiroko yekufamba kwemuchina, kuitira kuti muchina unofamba unogona kumira otomatiki, kudzosera kumashure, kuchinjika kumhanya kwekufamba kana otomatiki kudzoreredza mafambiro zvinoenderana neimwe nzvimbo kana sitiroko. Inoumbwa nemusoro wekushanda, yekubatanidza system uye imba. Yakakamurwa kuita yakananga-chiito (bhatani), rolling (rotary), micro-action uye musanganiswa.

Direct-acting limit switch: danho rekuita rakafanana nerebhatani, mutsauko ndewekuti imwe ibhuku, uye imwe inopokana nebhampa yechikamu chinofamba. Kana iyo yekukanganisa block pane yekunze inofamba chikamu inodzvanya bhatani kuti iyo yekuonana ifambe, kana chikamu chinofamba chichibva, iyo yekubata inozvigadzirisa zvakare pasi pechiito chechirimo.

Kutenderedza muganho switch: Kana iyo yekumisa simbi (kudhumhana block) yemuchina unofamba ichitsikirirwa pane roller yeinogadzika switch, tsvimbo yekufambisa inotenderera pamwe chete neshaft inotenderera, kuitira kuti cam issundire chivharo chinokonzeresa, uye kana chivharo chinobata. inorova imwe nzvimbo, inosundira micro movement Iyo switch inoshanda nekukurumidza. Kana simbi yekumisa pa roller yabviswa, chitubu chekudzoka chinogadzirisa chinja chekufamba. Iyi ivhiri imwe otomatiki kudzoreredza muganho switch. Uye maviri-mavhiri anotenderera mhando yekufamba switch haigone kupora otomatiki, uye kana ichivimba nemuchina unofamba kuti ufambe wakanangana nedivi, chivharo chesimbi chinorovera mune imwe roller kuti idzorere.

A micro switch is snap switch inofambiswa nekumanikidza. Nheyo yekushanda kwayo ndeyekuti simba rekunze remagetsi rinoshanda parutsanga rwechiito kuburikidza nechinhu chekufambisa (pini yepini, bhatani, lever, roller, nezvimwewo), uye mushure mekunge simba raunganidzirwa kunzvimbo yakakosha, chiitiko chekare chinogadzirwa, saka. kuti iyo inofamba inosangana pamagumo emutsanga wekuita Pfungwa uye yakagadziriswa yakagadziriswa inokurumidza kubatanidzwa kana kubviswa. Kana simba riri pachinhu chekufambisa chikabviswa, tsanga yekuita inoburitsa reverse action force, uye kana reverse stroke yechinhu chekutapurirana ichisvika padanho rakakosha rekuita kwetsanga, reverse action inopedzwa ipapo ipapo. Iyo yekubata chinhambwe cheiyo micro switch idiki, chiito sitiroko ipfupi, simba rekutsikirira idiki, uye yeku-off inokurumidza. Kumhanya kwekuita kwekubata kwayo kunofamba hakunei nechekuita nekumhanya kwechinhu chekufambisa. Iyo yakakosha mhando ye micro switch is push pini mhando, iyo inogona kutorwa kubva bhatani pfupi sitiroko mhando, bhatani hombe sitiroko mhando, bhatani rakawedzera hombe sitiroko mhando, roller bhatani mhando, tsanga roller rudzi, lever roller rudzi, ruoko rupfupi rudzi, ruoko rurefu. mhando etc.

Iyo mechanical valve limit switch inowanzo tora micro switch ye passive contact, uye switch form inogona kukamurwa kuita: single pole kaviri kukanda SPDT, single pole single throw SPST, double pole kaviri kukanda DPDT.

2. Proximity limit switch

Proximity switch, inozivikanwawo se-isina-contact yekufamba switch, haingogone kutsiva yekufamba switch nekubata kuti ipedze kudzora kufamba uye kudzivirira muganhu, asi zvakare inoshandiswa pakuverenga kwakakwira, kuyerwa kwekumhanya, kudzora nhanho yemvura, kuona saizi yechikamu, otomatiki kubatana kwe. kugadzirisa maitiro kumirira. Nekuti ine hunhu hweasina-contact trigger, kukurumidza kuita kukurumidza, chiito mukati mekuona kwakasiyana madaro, yakagadzikana uye pulse-isina chiratidzo, yakagadzikana uye yakavimbika basa, hupenyu hurefu, yakakwirira kudzokorora chinzvimbo uye kuchinjika kune dzakaoma nharaunda dzekushanda, nezvimwe. saka Inoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri senge maturusi emuchina, machira, kudhinda, uye mapurasitiki.

Proximity switches yakakamurwa zvinoenderana nemusimboti wekushanda: kunyanya yakakwira-frequency oscillation mhando, Horo mhando, ultrasonic mhando, capacitive mhando, musiyano coil mhando, yekusingaperi magineti mhando, nezvimwe. tyaira chinja rutsanga kuti ubudise chiratidzo.

Differential coil type: Inoshandisa eddy ikozvino uye shanduko yemagnetic field inogadzirwa kana chinhu chaonekwa chinosvika, uye inoshanda kuburikidza nemusiyano pakati peiyo coil yekuona uye coil yekuenzanisa. Capacitive proximity switch: Inonyanya kuumbwa ne capacitive oscillator uye yemagetsi dunhu. Iyo capacitance inowanikwa pane yekunzwa interface. Kana chinhu chasvika, chinozunguzika nekuda kwekuchinja kukosha kwayo kwekubatanidza capacitance, nekudaro ichigadzira oscillation kana kumisa oscillation kuti ibudise chiratidzo chinobuda. kuwedzera kuchinja. Horo yepedyo switch: Inoshanda nekushandura magineti masaini kuita magetsi emagetsi kubuda, uye kubuda kwayo kune basa rekuchengetedza ndangariro. Iyo yemukati magineti inonzwa mudziyo inongonzwa kune iyo magnetic field perpendicular kusvika kumagumo chiso che sensor. Kana iyo magineti danda S yakatarisana neiyo yepedyo switch, iyo inobuda yepedyo switch ine kusvetuka kwakanaka, uye kubuda kwacho kwakakwira. Kana iyo magineti danda N yakatarisana neiyo yepedyo switch, iyo inobuda yakaderera. level.

Ultrasonic proximity switch: Inonyanya kuumbwa nepiezoelectric ceramic sensors, midziyo yemagetsi yekuparadzira masaisai e ultrasonic uye kugamuchira mafungu anoratidzwa, uye inodzorwa-inodzorwa bhiriji switch yekugadzirisa iyo yekuona huwandu. Inokodzera kuona zvinhu zvisingagoni kana kubatwa. Basa rayo rekutonga harivhiringidziki nezvinhu zvakadai senzwi, magetsi, uye chiedza. Iyo yekuona tarisiro inogona kunge iri chinhu chakasimba, mvura kana hupfu mamiriro, chero bedzi ichigona kuratidza ultrasonic mafungu.

High-frequency oscillation proximity switch: Inokonzerwa nesimbi, inonyanya kuumbwa nezvikamu zvitatu: high-frequency oscillator, integrated circuit kana transistor amplifier uye chigadzirwa chekubuda. Nheyo yayo yekushanda ndeye: iyo coil ye oscillator inogadzira inochinjika magineti pane inoshanda pamusoro peiyo switch, kana chinhu chesimbi chinosvika panzvimbo inoshanda, iyo eddy ikozvino inogadzirwa mukati mechinhu chesimbi inotora simba reiyo oscillator, zvichiita kuti oscillator kumisa kuzunguza. Iwo maviri masaini e oscillation uye vibration kumira kweiyo oscillator inoshandurwa kuita mabhinari ekuchinja masaini mushure mekuumbwa uye kukwidziridzwa, uye masaini ekudzora ekuchinja anobuda.

Iyo magnetic induction valve limit switch inowanzo tora iyo electromagnetic induction proximity switch ye passive contact, uye switch form inogona kukamurwa kuita: single pole kaviri kukanda SPDT, single pole single kanda SPSr, asi hapana kaviri danda kukanda DPDT. Iyo magineti induction inowanzo patsanurwa kuita 2-waya inowanzo kuvhurika kana kuvharika, uye iyo 3-waya yakafanana ne-single-pole kaviri-kanda SPDT, isina kuvhurika uye kazhinji yakavharwa.
