Emagama Labalulekile:Inkinobho yemkhawulo wemshini; Inkinobho yemkhawulo wekusondzelana

1. Inkinobho yemkhawulo wemshini

Imvamisa, loluhlobo lwekushintja lusetjentiselwa kunciphisa indzawo noma kushaya kwekuhamba kwemshini, kwentela kutsi imishini lehambako ikhone kuma ngekuzenzakalela, kuhamba lokubuyela emuva, kuhamba ngesivinini lesigucukako noma kuhamba lokutentakalelako lokubuyela emuva ngekuya kwesikhundla lesitsite noma kushaya. Ihlanganisa inhloko lokusebenta, uhlelo lokutsintsana kanye nendlu. Ihlukaniswe yaba ngco-sento (inkinobho), kugicita (rotary), micro-sento kanye nenhlanganisela.

Direct-acting umkhawulo switch: isimiso sesenzo sifana naleso inkinobho, umehluko kutsi munye manual, bese lomunye ushayisana bumper ingxenye lehambako. Uma ibhulokhi yemtselela kulencenye lehambako yangaphandle icindezela inkinobho kwenta kutsintsana kuhambe, uma lencenye lehambako ihamba, lotsintsako uyatentela kabusha ngaphansi kwesento sentfwasanhlobo.

Rolling limit switch: Uma insimbi yekumisa (ibhulokhi yekushayisana) yemshini lohambako icindetelwa ku-roller ye-switch yemkhawulo, induku yekudlulisela ijikeleta kanye neshaft lejikeletako, kute i-cam iphushe ibhulokhi yemtselela, futsi uma ibhulokhi yemtselela ishaya indzawo letsite, iphusha kuhamba kwe-micro quick Le switch isebenta. Uma insimbi yekuma ku-roller isuswa, intfwasanhlobo yekubuya isetha kabusha switch yekuhamba. Lena yi-switch yemkhawulo wekuvuselela lokuzenzakalelayo kwelisondo linye. Futsi switch yekuhamba yeluhlobo lwemasondvo lamabili lejikeletako ayikhoni kululama ngekuzenzakalela, futsi uma ithembele emshinini lohambako kutsi uhambe ngendlela lephikisako, le-stopper yensimbi ishaya lenye i-roller kute iyibuyisele.

I-micro switch yi-snap switch lesebenta ngekucindzeteleka. Umtsetfo wayo wekusebenta kutsi emandla emshini langaphandle asebenta emhlanga wesento nge-elementi yekudlulisela (cindezela pin, inkinobho, lever, roller, njll), futsi ngemuva kwekutsi amandla abutselwe ephuzwini lelibucayi, sento lesisheshako siyakhicitwa, kute kutsintsana lokuhambako ekupheleni kwemhlanga wesento Liphuzu kanye ne-disc lecinile conne conne. Uma emandla kulentfo yekudlulisela asuswa, lomhlanga wesento ukhicita emandla ekusebenta labuyela emuva, futsi uma kushaya lokubuyela emuva kwentfo yekudlulisela kufika endzaweni lebalulekile yesento semhlanga, lesento lesibuyela emuva siyaphelelwa ngekushesha. Ibanga lekutsintsana le-micro switch lincane, stroke sesenzo sifishane, emandla ekucindzetela mancane, futsi ku-on-off kuyashesha. Ijubane lesento sekutsintsana kwayo lokuhambako akuhlangene nesivinini sesenzo se-elementi yekudlulisela. Luhlobo lolusisekelo lwe-micro switch luhlobo lwe-push pin, lolungatsatfwa kusuka enkinobheni emfushane stroke uhlobo, inkinobho enkulu stroke uhlobo, inkinobho extra enkulu stroke uhlobo, roller inkinobho uhlobo, umhlanga roller uhlobo, lever roller uhlobo, emfushane uhlobo umkhono, uhlobo umkhono eside njll.

Le switch yemkhawulo wevalve yemshini ivame kwemukela i-micro switch yekutsintsana lokungekho, futsi ifomu le-switch lingahlukaniswa libe: i-pole yinye lephindvwe kabili i-SPDT, i-SPST lephindvwe kabili i-pole yinye, i-DPDT lephindvwe kabili.

2. Inkinobho yemkhawulo wekusondzelana

Kusondzelana switch, futsi kwatiwa ngekutsi non-contact travel switch, angeke kuphela esikhundleni travel switch ngekutsintsana kucedza kulawula travel kanye umkhawulo ukuvikelwa, kodwa futhi kusetjentiswe kubala eliphezulu, ijubane ukukala, uketshezi lizinga ukuzipha, ingxenye usayizi ukuthola, uxhumano automatic tinchubo kucubungula ukulindza. Ngoba inetimphawu non-kutsintsana trigger, ijubane lesenzo lesisheshako, sento ngaphakatsi kwemabanga lehlukene ekutfola, luphawu loluzinzile nalolukhululekile lwe-pulse, umsebenti lozinzile nalowetsembekile, imphilo lendze, kuciniseka kwekuphindzaphindza lokusezingeni leliphakeme kanye nekuvumelana netindzawo tekusebenta letilukhuni tepulasitiki, njll., ngako-ke Isetjentiswa kakhulu ku-princh umbhalo we-industrial, njll.

Emaswitshi ekusondzelana ahlukaniswe ngekuya kwesimiso sekusebenta: ikakhulukati luhlobo lwe-oscillation lesetulu, luhlobo lweHholo, luhlobo lwe-ultrasonic, luhlobo lwe-capacitive, luhlobo lwekhoyili leyehlukile, luhlobo lwemaginethi lohlala njalo, njll.

Luhlobo lwekhoyili lehlukile: Isebentisa i-eddy current kanye nekushintja kwensimu yamagnetic leyakhiwa uma intfo letfolakele isondzela, futsi isebenta ngemehluko emkhatsini wekhoyili yekutfola kanye nekhoyili yekucatsanisa. Inkinobho yekusondzelana lokunemandla: Ikakhulukati yakhiwe yi-oscillator lenemandla kanye nesiyingi se-elekthronikhi. I-capacitance yayo isendaweni yesikhombisi sekuzwa. Uma intfo isondzela, itawunyakata ngenca yekushintja linani layo le-coupling capacitance, ngaleyondlela ikhicite kunyakata noma kumisa kunyakata kwentela kukhicita luphawu lwekuphuma. lushintjo lolunyenti kakhulu. Hall proximity switch: Isebenta ngekugucula timphawu temagnetic tibe ngumphumela wesiginali kagesi, futsi umphumela wayo unemsebenti wekugcina inkumbulo. Ledivayisi lengekhatsi lebucayi yemagnetic ibucayi kuphela enkhundleni yamagnetic lecondzile ebusweni bekugcina be-sensor. Uma i-magnetic pole S ibhekene ne-switch yekusondzelana, lokukhishwa kwe-switch yekusondzelana kunekugcuma lokuhle, futsi lokukhishwako kusetulu. Uma i-magnetic pole N ibhekene ne-switch yekusondzelana, lokukhiphako kuphansi. lingeneko.

Ultrasonic edvute switch: It ikakhulukati yakhiwe piezoelectric tinzwa ceramic, tintfo te-elekthronikhi tekudlulisela emagagasi ultrasonic kanye nekutfola emagagasi labonakalako, kanye luhlelo-lawulwa luhlelo ibhuloho switch ukulungisa uhla ukutfola. Ilungele kutfola tintfo letingeke titsintwe noma letingatsintfwa. Umsebenti wayo wekulawula awuphazanyiswa tintfo letinjengemsindvo, gezi, kanye nekukhanya. Lihloso lekutfola lingaba yintfo lesesimeni lesicinile, lesiketshezi noma sempuphu, uma nje ingakhombisa emagagasi e-ultrasonic.

Inkinobho yekusondzelana kwemvamisa lesetulu: Kubangelwa yinsimbi, ikakhulukati yakhiwe tincenye letintsatfu: i-oscillator lesetulu yemvamisa, isekethe lehlanganisiwe noma i-transistor amplifier kanye nedivayisi yekukhipha. Umtsetfo wayo wekusebenta kutsi: ikhoyili ye-oscillator ikhicita insimu yemagnetic leshintjashintjako endzaweni lesebentako ye-switch , uma intfo yensimbi isondzela endzaweni lesebentako, i-eddy current lekhicitwa ngekhatsi kwentfo yensimbi itawutsatsa emandla e-oscillator, kwenta kutsi i-oscillator iyekele kudvudvuta. Letimphawu letimbili tekunyakata kanye nekuma kwekudvudvuta kwe oscillator tiguculwa tibe timphawu tekushintja letimbili ngemuva kwekubunjwa kanye nekukhuliswa, bese timphawu tekulawula kushintja tiyaphuma.

Le switch yemkhawulo wevalve ye-magnetic induction ivame kwemukela i-electromagnetic induction yekusondzelana yekutsintsana lokungekho, futsi ifomu lekushintja lingahlukaniswa libe: i-SPDT lephosa kabili i-pole yinye, i-SPSr lephosa i-pole yinye, kepha kute i-DPDT lephindvwe kabili. Le induction yamagnetic ivame kuhlukaniswa ibe yi 2-wire levame kuvuleka noma levame kuvalwa, bese le 3-wire ifana ne single-pole double-throw SPDT, ngaphandle kwekuvuleka lokujwayelekile futsi kuvalwe ngalokuvamile.

Tianjin Tanggu Ivalvu Yekuvala Emanti Inkampanilokukhetsekile kuivalvu yevivane, Ivalvu yesango, Hlola ivalvu, Y sisefo, Ivalvu yekulinganisa, njll.
