MAGNABEND ISIKHOKELO sokudutyulwa kwenkathazo
Isikhokelo sokuJonga iNgxaki
Oku kulandelayo kusebenza koomatshini baseMagnabend abenziwe yiMagnetic Engineering Pty Ltd ukuya kutsho malunga nonyaka ka-2004.
Ukusukela ekuphelelweni kwamalungelo awodwa omenzi wechiza (obuNjineli beMagnetic) abanye abavelisi ngoku benza oomatshini beMagnabend abasenokungafani ncam.Ke ngoko olu lwazi lungezantsi lusenokungasebenzi kumatshini wakho okanye lunokufuneka luhlengahlengiswe.
Indlela elula yokulungisa iingxaki zombane kuku-odola imodyuli yombane etshintshileyo kumenzi.Oku kubonelelwa ngesiseko sotshintshiselwano kwaye ke ngoko kuxabisa kakhulu.
Ngaphambi kokuba uthumele imodyuli yotshintshiselwano unokuthanda ukujonga oku kulandelayo:
Ukuba umatshini awusebenzi kwaphela:
a) Khangela ukuba umbane ukhona na kumatshini ngokujonga isibane somqhubi wenqwelomoya kwi-ON/OFF switch.
b) Ukuba umbane ukhona kodwa umatshini usafile kodwa uziva ushushu kakhulu ngoko ke ukunqunyulwa kwe-thermal kusenokuba kukhubekile.Kule meko linda de umatshini uphole (malunga nesiqingatha seyure) uze uzame kwakhona.
c) I-interlock yokuqala yezandla ezibini ifuna ukuba iqhosha le-START licinezelwe phambi kokuba umqheba utsalwe.Ukuba isiphatho sitsalwe kuqala ngoko ke umatshini awuyi kusebenza.Kwakhona kunokwenzeka ukuba i-beam egobayo ihambe (okanye ingqutywe) ngokwaneleyo ukusebenzisa "i-angle microswitch" phambi kokuba iqhosha le-START licinezelwe.Ukuba oku kuyenzeka qinisekisa ukuba isiphatho sityhalelwe umva ngokupheleleyo kuqala.Ukuba le yingxaki eqhubekayo ke ibonisa ukuba i-microswitch actuator ifuna ukulungiswa (jonga ngezantsi).
d) Enye into enokwenzeka kukuba iqhosha lokuQALA linokuba nempazamo.Ukuba uneModeli 1250E okanye enkulu jonga ukuba umatshini unokuqalwa ngelinye lamaqhosha e-START okanye i-footswitch.
e) Khangela kwakhona isinxibelelanisi senayiloni esidibanisa imodyuli yombane kunye nekhoyili yemagnethi.
f) Ukuba i-clampbar ayisebenzi kodwa i-clampbar ihlebekile ekukhutshweni kweqhosha loku-START oku kubonisa ukuba i-15 microfarad (10 µF kwi-650E) capacitor ayilungile kwaye kuyakufuneka itshintshwe.
Ukuba umatshini uvuthela iifusi zangaphandle okanye ii-breaker circuit breakers:
Oyena nobangela wokuziphatha kukuvuthelwa kwebhulorho-yokulungisa.Isilungisi esivuthelweyo sikholisa ukuba nesinye kwii-4 diode zangaphakathi ezimfutshane.
Oku kunokujongwa nge-multimeter.Ngemitha kuluhlu lwayo oluphantsi lokumelana jonga phakathi kwepere nganye yeetheminali.I-polarity enye ye-multimeter test lead kufuneka ibonise i-ohms engapheliyo kwaye i-polarity ebuyiselweyo kufuneka ibonise ufundo oluphantsi, kodwa ingabiziro.Ukuba nakuphi na ukuchasa ukufunda nguziro ngoko isilungisi sivuthelwe kwaye kufuneka sitshintshwe.
Qinisekisa ukuba umatshini ukhutshiwe kwisixhobo sombane phambi kokuba uzame ukulungisa kwangaphakathi.
Isilungisi endaweni efanelekileyo :
RS Components inombolo yenxalenye: 227-8794
Ubuninzi bangoku: 35 amps ngokuqhubekayo,
Ubukhulu bombane obuya umva: 1000 Volts,
Izikhululo: 1/4" qhagamshela ngokukhawuleza okanye 'Faston'
ixabiso malunga: $12.00
Omnye unobangela wokukhubeka kukuba ikhoyili yemagnethi inokuba mfutshane kumzimba wemagnethi.
Ukujonga oku kukhupha ikhonkco lekhoyili yemagnethi kwaye ulinganise ukuxhathisa, ukusuka kumbala obomvu okanye omnyama, ukuya kumzimba wemagnethi.Seta i-multimeter kuluhlu lwayo oluphezulu lokuxhathisa.Oku kufuneka kubonise infinity ohms.
Ngokufanelekileyo lo mlinganiselo kufuneka wenziwe nge "Megger meter".Olu hlobo lwemitha lujonga ukuchasana nombane ophezulu (ngokuqhelekileyo i-1,000 volts) isetyenzisiweyo.Oku kuya kufumana iingxaki ezifihlakeleyo zokuqhekeka kwe-insulation kunokuba zifumaneka nge-multimeter eqhelekileyo.
Ukonakaliswa kwe-insulation phakathi kwekhoyili kunye nomzimba wemagnethi yingxaki enkulu kwaye ngokuqhelekileyo kuya kufuna ukuba icoil isuswe kumzimba wemagnethi ukuze ilungiswe okanye ifakwe endaweni yekhoyili entsha.
Ukuba i-clamping yokukhanya iyasebenza kodwa i-clamping epheleleyo ayenzi:
Khangela ukuba "i-Angle Microswitch" iqhutywe ngokuchanekileyo.
[Olu tshintsho lusetyenziswa sisikwere (okanye esingqukuva) isiqwenga sobhedu esincanyatheliswe kwi-engile ebonisa indlela.Xa isiphatho sitsalwa umqadi wokugoba uyajikeleza ohambisa ukujikeleza kwi-actuator yobhedu.I actuator yona isebenzisa imicroswitch ngaphakathi kwindibano yombane.]
I-Microswitch actuator kwiModeli 1000E
(Ezinye iimodeli zisebenzisa umgaqo ofanayo)
I-Actuator njengoko ibonwa ngaphakathi kombane
indibano.
Tsala isiphatho ngaphandle kwaye ungene. Kuya kufuneka ukwazi ukuva i-microswitch icofa ON kunye ne-OFF (ukuba akukho ngxolo ingasemva engasemva).
Ukuba iswitshi ayicofa i-ON kunye ne-OFF ngoko ujiwule umqadi wokugoba phezulu ukuze i-actuator yobhedu ibonwe.Jikelezisa umqadi wokugoba phezulu naphantsi.I-actuator kufuneka ijikeleze ngokuphendula kwi-beam yokugoba (ide ibambe kwiindawo zayo zokumisa).Ukuba ayenzi njalo, inokufuna amandla okubambelela ngakumbi:
- Kwi-650E kunye ne-1000E amandla okubamba anganyuswa ngokususa i-actuator yobhedu kunye nokucudisa i-slit ivalwe (umz. nge-vice) ngaphambi kokuyibuyisela kwakhona.
- Kwi-1250E ukunqongophala kwamandla okubambisa ngokuqhelekileyo kuhambelana nezikrufu ezimbini ze-M8 zentloko ye-cap-head nakweyiphi na isiphelo se-actuator shaft engaqini.
Ukuba i-actuator iyajikeleza kwaye ibambe u-Kulungile kodwa ayicofa i-microswitch ngoko inokufuna ukulungiswa.Ukwenza oku qala ukhuphe iplagi yomatshini kwindawo yokukhupha umbane uze ususe ipaneli yokufikelela yombane.
a) KwiModeli 1250E indawo yokuvula iyakwazi ukulungiswa ngokujika isikrufu esidlula kwi-actuator.I-screw kufuneka ilungiswe ngendlela yokuba i-switch icofa xa umgca ophantsi we-beam egobayo uhambe malunga ne-4 mm.(Kwi-650E kunye ne-1000E uhlengahlengiso olufanayo luphunyezwa ngokugoba ingalo ye-microswitch.)
b) Ukuba i-microswitch ayicofa i-ON kunye ne-OFF nangona i-actuator isebenza ngokufanelekileyo ngoko ke iswitshi ngokwayo inokudityaniswa ngaphakathi kwaye iya kufuna ukutshintshwa.
Qinisekisa ukuba umatshini ukhutshiwe kwisixhobo sombane phambi kokuba uzame ukulungisa kwangaphakathi.
Ukutshintsha okufanelekileyo kweV3:
RS inombolo inxalenye: 472-8235
Umlinganiselo wangoku: 16 amps
V3 Isekethe
C= 'Eqhelekileyo'
NC= 'Ivalwe ngokuqhelekileyo'
HAYI= 'Ngesiqhelo ivuliwe'
c) Ukuba umatshini wakho ufakelwe iswitshi encedisayo ke qiniseka ukuba utshintshelwe kwindawo ethi "NORMAL".(Kuya kubakho ukucinezela ukukhanya kuphela ukuba iswitshi ikwindawo ethi "AUX CLAMP".)
Ukuba ukucinezela KULUNGILE kodwa iiClampbars azikhuphi xa umatshini Ecimile:
Oku kubonisa ukusilela kwe-reverse pulse demagnetising circuit.Esona sizathu sinokuthi sibe sisixhathisi samandla esingu-6.8 ohm esivuthelweyo.Khangela kwakhona zonke iidiode kunye nokubanakho ukuncamathela abafowunelwa kwi-relay.
Isixhasi esifanelekileyo sokubuyisela:
Element14 inxalenye No. 145 7941
6.8 ohm, 10 watt amandla okukala.
Iindleko eziqhelekileyo $1.00
Ukuba umatshini awuyi kugoba iphepha lokulinganisa elinzima:
a) Khangela ukuba umsebenzi ungaphakathi kwemigaqo yomatshini.Ngokukodwa qaphela ukuba kwi-1.6 mm (i-16 gauge) ukugoba ibha yokwandisa kufuneka ifakwe kwi-beam egobayo kwaye ubuncinane bobubanzi bomlomo buyi-30 mm.Oku kuthetha ukuba ubuncinci i-30 mm yemathiriyeli kufuneka iphume kumda wokugoba we-clampbar.(Oku kusebenza kuzo zombini i-aluminiyam kunye nentsimbi.)
Imilebe emincinci inokwenzeka ukuba ukugoba abukho ubude obupheleleyo bomatshini.
b) Kwakhona ukuba i-workpiece ayigcwalisi indawo phantsi kwe-clampbar ngoko ukusebenza kunokuchaphazeleka.Ukufumana iziphumo ezingcono hlala ugcwalisa isithuba phantsi kwe-clampbar ngeqhekeza lentsimbi elilingana nobukhulu obufanayo nomsebenzi.(Kweyona nto ibamba imagnethi ibambeneyo, isiqwenga sokugcwalisa kufuneka sibe yintsimbi nokuba isicwecwe asiyontsimbi.)
Le ikwayeyona ndlela ilungileyo yokusebenzisa ukuba kuyafuneka ukwenza umlebe omxinwa kakhulu kwindawo yokusebenza.
