I-AVT3172B - Isilawuli sokususa intuthu
Noma ubani owenza i-soldering njengendlela yokuzilibazisa ekhaya uyazi ukuthi kuyingozi kangakanani futhi ngesikhathi esifanayo kuyingozi ukukhipha imfucumfucu ye-solder. Kuyiqiniso ukuthi kunezixazululo eziningi ezenziwe ngomumo zokudonsa intuthu emakethe, kodwa ukusetshenziswa kwazo kuvame ukuba nzima. Isixazululo esiveziwe sikuvumela ukuthi ulungise kahle isivinini se-fan ngokuvumelana nezidingo zakho, ezinganciphisa kakhulu umsindo okhishwa umlandeli osebenzayo.
Yiqiniso, umqondo onjalo ngeke ubeke esikhundleni se-hood enhle yokukhipha, futhi isisombululo esihle kunazo zonke futhi esiphumelelayo kungaba ukuhlanganisa isiphepheli nge-ventilation duct. Kodwa-ke, ukusetshenziswa ngokuhambisana nokusetshenziswa kwe-cartridge yokuhlunga i-carbon kanye nokungena komoya okuvamile kwekamelo, kuzonciphisa kakhulu ingozi yokuhogela ngokuqondile kwe-solder. Ngaphezu kwalokho, uhlelo olwethulwe lungasetshenziswa kaningi - isibonelo, ngezinsuku ezishisayo luphelele njengomlandeli wetafula lomuntu siqu.
Incazelo yesakhiwo
Umdwebo we-schematic wesekethe uboniswa ku-Fig. 1. Lolu uhlelo lokusebenza lwakudala lwe-LM317 voltage stabilizer. Imojula kufanele inikwe amandla kusuka kupulaki evamile engu-12V exhunywe kusixhumi se-IN. I-Diode D1 ivikela isistimu kusuka ku-polarity ehlehlayo ye-voltage yokufaka, futhi ama-capacitor C1-C4 ahlunga le voltage. Ngamanani wezinto eziboniswe kumdwebo, ububanzi bokulungisa bukuvumela ukuthi usethe noma iyiphi i-voltage ebangeni ukusuka cishe ku-2 ukuya cishe ku-11 V ekuphumeni, okunikeza ukulawula okubushelelezi kwejubane le-fan exhunywe ku-OUT. Phuma.
Ukufakwa nokulungiswa
Umhlangano wesistimu ungowakudala futhi akufanele ubangele izinkinga. Ake siqale ngokuhlanganisa izinto ezincane ebhodini, bese siqeda ngokufaka irediyetha ngesistimu ye-U1 kanye ne-potentiometer. Faka ifeni ekugcineni usebenzisa izingcezu ezimfushane zezintambo ezicwebezelayo ezisiliva. Uchungechunge lwezimbobo ezifakwayo ezinensimu yethusi eveziwe zisetshenziselwa le njongo. Indlela yokuhlanganisa abalandeli iboniswa ezithombeni. Ipuleti lakhelwe ukumumatha abalandeli abangu-120mm kanye nogqinsi olungu-38mm. Indlela yokufaka ifeni ingokuzithandela, kuye ngezidingo kanye nokusetshenziswa okuhlosiwe kocingo.
