isingeniso
Njenge-"iziphetho zemizwa" zokulawula isifunda, ikhono lokuzivumelanisa nezimo lamanje lama-micro switch lithinta ngqo ukuphepha nokuthembeka kwemishini. Kusukela ekuqaliseni isignali encane yeuhlakaniphileNjengoba kunezimo eziningi zamandla kagesi ezimbonini, izinkinobho ezincane zezinhlobo ezahlukene zamandla kagesi ziqhuba ukuthuthukiswa okuhlakaniphile kwezimo ezahlukahlukene. Lesi sihloko sihlanganisa amazinga ezimboni kanye namacala ajwayelekile ukuhlaziya umqondo oyinhloko kanye nesiqondiso esisha sesicelo samanje.
Isimo sokuzivumelanisa nezimo
Ama-micro switch awafaneleki nje kuphela ohlotsheni olulodwa lwamandla kagesi, kodwa ukwakheka kwawo kungahlanganisa ububanzi obuvela ku-5mA kuya ku-25A. Izimo zokuzivumelanisa nezimo zifaka okulandelayo: okokuqala, kuma-currents amancane anomsinga ongaphansi kuka-1A, njengokuqalisa isignali yenzwa, ukulawulwa kwemishini yezokwelapha, njll., oxhumana nabo abafakwe igolide bayadingeka ukunciphisa ukumelana kokuxhumana nokuqinisekisa ukuqina kwesignali. Okulandelayo umbane ophakathi nendawo ophezulu (1-10A) onekhono lamandla kagesi kububanzi be-1-10A, njengokulawula amandla asekhaya kanye ne-electronics yezimoto (njengezingidi zeminyango) ezisebenzisa oxhumana nabo be-silver alloy ukumelana nokuguguleka kwe-arc. Okokugcina, kuma-currents aphezulu anomthamo wamandla kagesi ongu-10-25A, njengama-valve ephampu yezimboni kanye nezinqwaba zokushaja amandla amasha, kuyadingeka ukuqinisa isakhiwo sokucisha i-arc kanye nomklamo wokuxhumana we-break point kabili ukuze kwandiswe amandla okuphuka ngo-50%.
imikhiqizo ejwayelekile
Uchungechunge lwe-Omron D2F: lusekela imithwalo ye-DC engu-0.1A-3A, eyenzelwe ngqo ama-electronics abathengi, enokuphila okufika kumjikelezo wezigidi eziyi-10.Uchungechunge lwe-Honeywell V15: olukwazi ukumelana nemithwalo yezimboni engu-10A/250VAC, olunegumbi lokucisha i-arc ye-ceramic eyakhelwe ngaphakathi, olufanele ukulawula imoto. Konke kuyimikhiqizo yakudala.
Izinkomba ezibalulekile zokukhetha
Kubalulekile ukukhetha i-micro efanele shintsha kahle, futhi okulandelayo yizici eziyinhloko okufanele uzinake lapho ukhetha ama-micro afanele umthakathi. 1. Amapharamitha alinganisiwe: Ukuhlola ukuthi amapharamitha alinganisiwe ayahambisana yini ikakhulukazi kugxile ezicini ezimbili: i-voltage kanye ne-current. Ezimweni zokuxhumana, kuyadingeka ukuhambisana ne-grid standard (njenge-220VAC), kuyilapho ezimweni ze-DC, kufanele kunakwe i-voltage yesistimu (njenge-12VDC). Futhi kokubili i-steady-state current kanye ne-surge current kudingeka kucatshangelwe ngesikhathi esisodwa, nge-margin engu-20% egcinelwe ukushintsha kwe-valve ye-industrial pump valve.2.Izinto ezisetshenziswa yilaba ababili nazo ziyisici esibaluleke kakhulu: oxhumana nabo abafakwe igolide bavame ukusetshenziswa ezimweni ezisezingeni eliphansi lokunemba okuphezulu (njengemishini yezokwelapha), ezibiza kakhulu kodwa ezimelana nokushiswa kwe-oxidation okunamandla. Oxhumana nabo be-alloy yesiliva bayindlela engabizi kakhulu, efanelekile ezimweni zomthwalo ophakathi njengezinto zasekhaya, kodwa zidinga ukulungiswa njalo ukuze kuvinjelwe ukubola.3.Iphuzu lesithathu ukukwazi ukuzivumelanisa nezimo zemvelo: Ukuvikelwa kwe-IP67 noma ngaphezulu kuyadingeka ezindaweni ezinomswakama, kanye namamodeli angamelana nokushisa okungu-150℃noma ngaphezulu kufanele kukhethwe ezimweni zokushisa okuphezulu (njengezingxenye zenjini yemoto). Elinye iphuzu elibalulekile amazinga okuqinisekisa: isitifiketi se-UL siyimpoqo emakethe yaseNyakatho Melika, ukumaka i-CE kuyadingeka e-European Union, kanye nesitifiketi sokuphepha se-ISO 13849-1 siyanconywa emishinini yezimboni.
Izingozi zokusebenzisa kabi kanye nezixazululo
Kunezinye izimo ezivamile zengozi: Imithwalo ye-AC isebenzisa kabi amaswishi e-DC, okubangela ukuguguleka kokuthintana (njengokwehluleka komkhiqizi othile wemishini yasekhaya ukukhetha amaswishi anikezelwe yi-AC, okuholela ekwehlulekeni kokulawula umnyango we-microwave).Ukukhethwa okunganele kwezimo zamandla aphezulu kuholele ekushiseni ngokweqile nasekuncibilikeni kwamaswishi (ingozi yokuphepha yenzeke enkampanini yesiteshi sokushaja ngenxa yokuntuleka kwemingcele yamandla agciniwe).
Isixazululo
Ukubalwa kwepharamitha okunembile: Hlola izici zomthwalo kusengaphambili ngesofthiwe yokulingisa ukuze ugweme umbono ongalungile "wokukhetha okusekelwe kokuhlangenwe nakho".Ukuhlolwa nokuqinisekiswa komuntu wesithathu: Nika ilabhorethri igunya lokwenza ukuhlolwa kokushisa okuphezulu nokuphansi, ukudlidliza, kanye nokuphila (njenge-IEC 61058 standard).
Izitayela Zemboni
Kunezindlela ezintathu eziyinhloko embonini yamanjeUkuhlanganiswa okuhlakaniphile: ama-chip okuzwa ingcindezi ahlanganiswe nama-micro switch ukuze kufezwe impendulo yamandla elinganisiwe (njengezinhlelo zokuthinta zamarobhothi).Ukukhiqizwa Okuluhlaza: I-EU RoHS 3.0 ivimbela izinto eziyingozi futhi ikhuthaza ukuthandwa kwezinto zokuthinta ezingenayo i-cadmium.Ukushintshaniswa kwemikhiqizo yasekhaya: Imikhiqizo yaseShayina efana neKaihua Technology inyuse isikhathi sokuphila komkhiqizo safinyelela izikhathi eziyizigidi ezingu-8 futhi yehlise izindleko ngo-40% ngokusebenzisa i-nano- ubuchwepheshe bokumboza.
isiphetho
Kusukela kuzimpawu zezinga le-milliampere kuya kumashumi ama-ampere okulawula amandla, ikhono lamanje lokuzivumelanisa nezimo lama-micro switch lihlala lidlula imingcele. Ngokungena kwezinto ezintsha nobuchwepheshe obuhlakaniphile, le "ngxenye encane" izoqhubeka nokunika amandla igagasi lokuthuthukisa le-Industry 4.0 kanye ne-consumer electronics. Isikhethi sidinga ukusebenzisa amapharamitha esayensi njengamaphuzu okubambelela kanye nezidingo zesimo njengesiqondiso ukuze kwandiswe ukukhishwa kwenani laso lobuchwepheshe.
