Kwiisekethe zeemoto, ukuhanjiswa kweemoto zizinto ezibalulekileyo zokulawula, ziqinisekisa ukusebenza okuqhelekileyo kunye nokhuseleko lwesithuthi. Abagcini nje ngokulawula imisebenzi eyahlukeneyo yezithuthi kodwa bakwalikhonkco eliphambili ekuqinisekiseni ukuqhuba ngokukhuselekileyo. Ukukhetha ireyiji yemoto eyiyo ayinako ukukhulisa inkangeleko yemoto yakho kuphela kodwa ikwadlala indima ebalulekileyo kumaxesha anzima.
Iimoto zangaphakathi zikwaxhotyiswe ngezixhobo ezifana neeswitshi-iireyiyi.
Okulandelayo, xa ukhetha i-automotive relay, i-input and output parameters, kunye nezinto ezisingqongileyo kunye nokhuseleko, kufuneka ziqwalaselwe ukuhlangabezana neemfuno zokusetyenziswa kwesithuthi. Ngexesha lenkqubo yokukhetha, kufuneka siqwalasele ngokubanzi iinkalo ezininzi ezifana neeparitha zokufaka, iiparitha zemveliso, iiparitha zexesha, iimeko zokusingqongileyo, kunye nemimiselo yokhuseleko ukuqinisekisa ukuba i-relay ekhethiweyo ihambelana ngokugqibeleleyo kwaye yenza umsebenzi ojoliswe kuyo.
Xa sikhetha i-automotive relay, kufuneka siqwalasele izinto ezininzi ezibalulekileyo ukuqinisekisa ukusebenza okuqhelekileyo kunye nokhuseleko lwesithuthi.
Input Parameter Selection Principles
► Ugqaliselo lweParameter esisiseko
Xa sikhetha i-relay ye-automotive, kufuneka sigxininise kwiiparameters zokufakelwa ezifana ne-coil rated voltage, i-voltage esebenzayo, i-voltage yokukhulula, ukusetyenziswa kwamandla ekhoyili, ubuninzi obuqhubekayo bangoku, kunye nokumelana neekhoyili. Ngethuba lenkqubo yokukhetha, kufuneka siqinisekise ukuba ezi parameters zihambelana neemfuno zangempela zokuqinisekisa ukusebenza okuqhelekileyo kwe-relay.
► Impembelelo yoBubushushu obukwi-Ambient
Iiparameters zokusebenza ze-relays ziyahluka phantsi kweendawo ezahlukeneyo zokushisa, ezifuna ingqalelo ngokucophelela. Ukuhanjiswa kweemoto ngokuqhelekileyo kusebenza kwindawo ye-injini kunye neendawo zokuhlala zabagibeli, ezinomlinganiselo ophezulu wokushisa we-125 kunye ne-85℃ngokulandelelanayo. Kubalulekile ukuqaphela ukuba ukuxhathisa kwekhoyili kuyatshintsha ngobushushu be-ambient, echaphazela ukutsalwa kwerelay-ngaphakathi kunye nokukhulula i-voltages.
►IiNgqwalasela zoMbane kunye nokuSetyenziswa koMbane
Uyilo oluphezulu lwamandla ombane kufuneka luqwalasele impembelelo yokunyuka kobushushu kwikhoyili. Ukuhlangabezana neemfuno zombane ophantsi wokusebenza, iireyilayi zeemoto zihlala ziyilwe ngokusetyenziswa kwamandla aphezulu. Nangona kunjalo, umbane osetyenziswa kwikhoyili ixesha elide kufuneka ulawulwe ngaphakathi kwe-120% yombane olinganisiweyo. Ingakumbi kwindawo-zobushushu obuphezulu, iqondo lobushushu lekhoyili liyenyuka ngokukhawuleza, linyusa isantya sokuguga.
► Khupha Useto lweVolthage
Umbane wokukhulula we-DC kunye ne-AC relays kufuneka ube phakathi koluhlu olumiselweyo. Ukuba i-voltage eseleyo kwisekethe idlula olu luhlu, i-relay iya kusilela ukukhulula ngokufanelekileyo.
►Emva kwe-EMF kunye naManyathelo oKhuseleko
Ukukhetha amacandelo afanelekileyo afana ne-resistors okanye i-freewheeling diode inokunciphisa impembelelo ye-EMF yangasemva. Ukuze ugweme umonakalo kwiisekethe ze-elektroniki ukusuka kwi-EMF yangasemva, ii-relays ezixhotyiswe nge-resistors okanye i-freewheeling diode zingakhethwa, kodwa ukulungiswa kwe-polarity okuchanekileyo kufuneka kuqinisekiswe.
ImiGaqo yokuKhetha iParameter yePhulo
► Uhlobo lomfowunelwa kunye noLayisho
Xa ukhetha ukuhanjiswa kweemoto, iiparamitha zemveliso ezininzi kufuneka ziqwalaselwe ngokubanzi, kubandakanya nenani lamaqela oqhagamshelwano, uhlobo loqhagamshelwano, umthwalo woqhagamshelwano, izinto zoqhagamshelwano, ubomi bombane, kunye nobomi bomatshini. Ezi parameters zichaphazela ngqo ukusebenza kunye nokusebenza kwe-relay. Uhlobo loqhagamshelwano lukhethwe ngokusekelwe kwisicelo esithile, esichaphazela umphumo wokulawula isiphaluka.
► Iindidi ezahlukeneyo zemithwalo
I-Relays kufuneka ibe nemilinganiselo ethile yokuphatha imithwalo eyahlukeneyo ukuphepha umonakalo woqhagamshelwano. Iindidi ezahlukeneyo zemithwalo ziya kuba nemiphumo eyahlukileyo kubafowunelwa. Umzekelo, izibane ziya kuvelisa i-inrush current; imithwalo yeemoto iya kuvelisa umva i-EMF; Imithwalo ye-inductive iya kuvelisa i-electromagnetic induction surges, njl njl. Kwizicelo ezisebenzayo, ingqwalasela eyodwa kufuneka ihlawulwe kwiimpawu zohlobo lomthwalo, kwaye amanyathelo ahambelanayo kufuneka athathwe ukukhusela abafowunelwa.
► IiMathiriyeli zoQhagamshelwano kunye noKhuselo
Izinto zoqhagamshelwano kufuneka zibe neempawu ezifana nokuchasana okuncinci kunye nokuxhathisa ukubola. Xa ukhetha imathiriyeli yokunxibelelana nonxibelelwano, qinisekisa ukuba ukuxhathisa koqhagamshelwano kuhlala kuphantsi kwaye kuzinzile, kwaye zinokumelana ne-corrosion elungileyo kunye -neempawu zokuncamathelisa.
Ixesha kunye nokuKhethwa kweMeko yokusiNgqongileyo
► Iiparamitha zexesha elingundoqo
Xa ukhetha ii-relays, iiparameters zexesha ezifana nexesha lokusebenza zinempembelelo encinci kwii-auto relays, kodwa kwii-relays ezidibeneyo, i-frequency flashing kufuneka ithathelwe ingqalelo. Ngelixa ixesha lokusebenza ngokuqhelekileyo ingeyiyo eyona nkxalabo iphambili yokuhanjiswa kweemoto, ukuphindaphindeka okudanyazayo kunye nexesha lokulibaziseka liba yingqwalasela enkulu yokuhanjiswa okudibeneyo.
►ukuphatha iMeko yokusiNgqongileyo
Ukuhanjiswa kufuneka kumelane namaqondo obushushu aphezulu kunye neemeko ezifumileyo, ezifuna uyilo olutywiniweyo. Xa sikhetha iireyidi, kufuneka siqwalasele ngokupheleleyo iimeko ezahlukeneyo zokusingqongileyo abaya kujongana nazo, ezifana nobushushu obuphezulu, ubushushu obuphantsi, kunye neemeko zokufuma. Ubushushu obuphezulu kunye neendawo ezifumileyo, ngakumbi, zinokukhawulezisa ukuguga kwe-relay; ukukhetha uyilo olutywiniweyo kunokukhusela ngokufanelekileyo ukuzinza kwayo kokusebenza.
