Intshayelelo
Kwimimandla efana nolawulo lwemizi-mveliso, izixhobo ze-elektroniki zabathengi, kunye nezixhobo zonyango,i-micro iiswitshi, ngobukhulu bazo obuncinci, zidlala indima ebalulekileyo ekudlulisweni kwesignali kunye nokujonga imeko. Nangona kunjalo, phantsi kokusebenza komthwalo omninzi ixesha elide okanye impembelelo yeendawo ezinzima, i-micro Iiswitshi zinokudibana neengxaki ezahlukeneyo zokungaphumeleli. Ngokusebenzisa uHlalutyo lweMowudi yoKuhluleka (FMEA) kunye namanyathelo okuthintela ajolise kuko, ukuthembeka kwezixhobo kunokuphuculwa ngokufanelekileyo kwaye iimpazamo ezinokubakho zinokuncitshiswa.
Iindlela eziqhelekileyo zokungaphumeleli: Impembelelo enkulu emva kweziphene ezincinci
Ukusilela kwe-micro Iiswitshi zihlala ziqala "ngezinto ezingaqhelekanga". Umzekelo, ukunamathela koqhagamshelwano kufana neswitshi "ebambekileyo". Nje ukuba icinezelwe, ayinakuqhawulwa ngokuqhelekileyo, nto leyo enokukhokelela ekusebenzeni okuqhubekayo kwesixhobo okanye nokulahlekelwa lulawulo. Unxibelelwano olubi lubonakala njengemiqondiso engapheliyo, efana nokungaphenduli xa ucofa imawusi okanye ukuqalisa okungeyonyani kwee-alamu zesixhobo. Ukuqhekeka kokudinwa kweReed kudla ngokuvela kwiimeko eziqhelekileyo zokusebenza. Umzekelo, emva kokuba iswitshi yokufumanisa i-paper jam yeprinta isebenza ixesha elide, i-metal reed inokuqhekeka ngenxa yokuncipha kwe-elastic, okukhokelela ekusileleni kokufumanisa. Ukuqhekeka kwe-casing kunye nokuxinana kwesenzo kunxulumene kakhulu nokusingqongileyo. Kwimeko enomswakama, i-casing iyabola kwaye inciphe, okanye uthuli lungene ngaphakathi kwe-switch kwaye luvale isakhiwo soomatshini, zombini ezinokubangela ukuba iswitshi ingasebenzi kakuhle. Ezi ngxaki zinokubonakala zincinci, kodwa zinokubangela ukungasebenzi kwezixhobo, iingozi zokhuseleko okanye neengozi. Ke ngoko, kubalulekile ukuchonga iindlela zokungaphumeleli kwangaphambili.
Uhlalutyo lweZinto Ezibangela Ukusilela: "Ikhonkco Lempazamo" Elidityaniswe Nezinto Ezininzi
Ukusilela kudla ngokuba ngumphumo wokubekwa kwezinto ezininzi. Ukulayisha kakhulu yimbangela eqhelekileyo. Umzekelo, xa iswitshi enombane olinganisiweyo we-1A isoloko ivezwa kumbane we-1.5A, ukukhukuliseka kwe-arc kwiindawo zoqhagamshelwano kuyaqina, kwaye i-oxidation yomphezulu ikhokelela ekudibaneni okubi. Xa izixhobo ziqalwa kwaye zimiswa rhoqo, ubushushu obuphezulu obuveliswa yi-arc yombane bunokutshisa "ii-contacts", nto leyo ebangela imingxunya okanye ukunamathela. Izinto ezingqongileyo nazo akufuneki zithathwe lula. Ukuhlasela kweegesi ezirhabaxa kunye namasuntswana kwindawo yothuli kwiindawo zokusebenzela iikhemikhali kuya kukhawulezisa ukuguga kwegobolondo langaphandle kunye neendawo zangaphakathi. Ukothuka koomatshini kunye nokungcangcazela kunokubangela ukusasazwa kwamandla okungalinganiyo kwingcongolo, okwandisa umngcipheko wokuphuka kokudinwa. Ngaphezu koko, uyilo olungafanelekanga kunye nokukhetha "sisiphene esingokwemvelo". Ukuba inqanaba lokukhusela iswitshi alanelanga kodwa lisetyenziswa kwindawo enomswakama ophezulu, okanye ukuba iiparameter zomthwalo azihambelani neemeko zokusebenza zokwenyani, konke kuya kubeka ingozi efihlakeleyo yokusilela.
Amanyathelo okuthintela: Yakha "inethi yokukhusela" kulo lonke uthotho
Eli shishini liphuhlise inkqubo yokuthintela evuthiweyo yezizathu zokungaphumeleli. Ukusetyenziswa okuncitshisiweyo sisiseko. Umzekelo, xa ukhetha iswitshi enomlinganiselo wamandla oqhagamshelwano ophindwe ka-1.5 kunomthwalo wokwenyani, kufuneka kushiywe umda wokhuseleko owaneleyo. Uyilo lwesekethe yokhuseleko lunokunciphisa ingozi yee-arcs zombane. Isekethe ye-RC buffer iqhagamshelwe ngaxeshanye kuzo zombini iziphelo zeswitshi okanye i-relay iqhagamshelwe kuthotho ukuze kufunxwe umbane ohambayo kwaye kwandiswe ubomi benkonzo yabaqhagamshelana. Ukuvalwa kwendalo kubalulekile. Ibhokisi yokukhusela ekumgangatho we-IP67 kufuneka ikhethwe, kwaye iiringi zokuvala kufuneka zisetyenziswe ukuvimba uthuli kunye nokufuma. Kwiimeko ezifana nezixhobo zonyango, izixhobo ezingamelaniyo nokubulala iintsholongwane nazo kufuneka ziqwalaselwe. Ukuqinisa ulwakhiwo kunokunyusa ukumelana nempembelelo. Ngokwenza ngcono izinto zengcongolo (ezifana nokusebenzisa izinto zentsimbi engagqwaliyo okanye i-alloy) kunye nokongeza izixhobo zomda woomatshini, umonakalo woxinzelelo obangelwa kukungcangcazela ungancitshiswa. Ukugcinwa rhoqo "lukhathalelo olufunyenweyo". Kubandakanya ukwenza izicwangciso zokuhlola, ukucoca i-oxide kumphezulu woqhagamshelwano, ukuthambisa iindawo ezihambayo, kunye nokutshintsha ngokukhawuleza iiswitshi ezindala ukuze kususwe iimpazamo ebuntwaneni bazo.
Isiphelo
Ukususela kwimigca yemveliso ezenzekelayo yemizi-mveliso ukuya kwizixhobo ze-elektroniki zasekhaya, ukusebenza okuthembekileyo kwe-micro Iiswitshi zibalulekile ekuzinzeni kwenkqubo yonke. Ngokuqhuba uhlalutyo lwendlela yokusilela ukuchonga "amanqaku omngcipheko" uze wakhe "udonga olukhuselayo" ngeendlela ezifana nokunciphisa uyilo, ukhuseleko lokusingqongileyo, kunye nokugcinwa rhoqo, kungekuphela nje ukuba izinga lokusilela kwezixhobo linokuncipha, kodwa nobomi benkonzo bunokwandiswa. Ekulandeleni kwanamhlanje imveliso esebenzayo kunye nobomi obulula, ukunikel' ingqalelo "kwiinkcukacha ezincinci" ze-micro iiswitshi "bubulumko obukhulu" bokukhusela ukusebenza ngokukhuselekileyo kwezixhobo.
