MAGNABEND TROUBLE SHOOTING GUIDE
Vuto Kuwombera Guide
Zotsatirazi zikugwira ntchito ku makina a Magnabend opangidwa ndi Magnetic Engineering Pty Ltd mpaka pafupifupi chaka cha 2004.
Popeza kutha kwa ma patent (a Magnetic Engineering) opanga ena tsopano akupanga makina a Magnabend omwe sangakhale ofanana ndendende.Chifukwa chake zomwe zili pansipa sizingagwire ntchito pamakina anu kapena zingafunikire kusinthidwa.
Njira yosavuta yothetsera mavuto amagetsi ndikuyitanitsa gawo lamagetsi lolowa m'malo kuchokera kwa wopanga.Izi zimaperekedwa posinthanitsa ndi chifukwa chake ndi zamtengo wokwanira.
Musanatumize gawo losinthira mungakonde kuwona zotsatirazi:
Ngati makina sagwira ntchito konse:
a) Onetsetsani kuti mphamvu ilipo pamakina poyang'ana kuwala kwa woyendetsa mu ON/OFF switch.
b) Ngati mphamvu ilipo koma makinawo akadafa koma akumva kutentha kwambiri ndiye kuti chodulidwacho chikhoza kugwa.Apa dikirani mpaka makinawo atazizira (pafupifupi hafu ya ola) ndikuyesanso.
c) Kulumikizana koyambira ndi manja awiri kumafuna kuti batani la START likanikizidwe chisindikizo chisanakokedwe.Ngati chogwiriracho chikoka kaye ndiye kuti makinawo sagwira ntchito.Komanso zitha kuchitika kuti chipika chopindika chimayenda (kapena kugwedezeka) mokwanira kuti igwiritse ntchito "angle microswitch" batani la START lisanayambe kukanikiza.Izi zikachitika, onetsetsani kuti chogwiriracho chikukankhidwira m'mbuyo poyamba.Ngati ili ndi vuto losalekeza ndiye zikuwonetsa kuti chowongolera cha microswitch chikufunika kusintha (onani pansipa).
d) Kuthekera kwina ndikuti batani la START likhoza kukhala lolakwika.Ngati muli ndi Model 1250E kapena yokulirapo ndiye muwone ngati makinawo atha kuyambitsidwa ndi mabatani ena a START kapena footswitch.
e) Onaninso cholumikizira cha nayiloni chomwe chimalumikiza gawo lamagetsi ndi koyilo yamagetsi.
f) Ngati clamping sikugwira ntchito koma clampbar idumpha pakatulutsidwa batani la START ndiye izi zikuwonetsa kuti 15 microfarad (10 µF pa 650E) capacitor ndi yolakwika ndipo ifunika kusinthidwa.
Ngati makinawo akuwomba ma fuse akunja kapena maulendo othamanga:
Chomwe chimapangitsa kuti izi zitheke ndikuwombedwa mlatho wowongolera.Chowombetsanso chowomberedwa nthawi zambiri chimakhala ndi diode imodzi yamkati mwake yofupikitsidwa.
Izi zitha kuwonedwa ndi multimeter.Ndi mita yomwe ili pamtunda wake wotsika kwambiri, fufuzani pakati pa ma terminals.Polarity imodzi ya ma multimeter test lead ikuyenera kuwonetsa ma infinity ohms ndipo polarity yotembenuzidwa iyenera kuwonetsa kuwerenga kochepa, koma osati ziro.Ngati kukana kulikonse kuli zero ndiye kuti chowongoleracho chimawomberedwa ndipo chiyenera kusinthidwa.
Onetsetsani kuti makinawo achotsedwa pamagetsi musanayese kukonzanso mkati.
Chotsitsimutsa choyenerera:
Nambala ya zigawo za RS: 227-8794
Max yamakono: 35 amps mosalekeza,
Magetsi obwereranso kwambiri: 1000 Volts,
Ma terminal: 1/4 "kulumikiza mwachangu kapena 'Faston'
Pafupifupi mtengo: $12.00
China chomwe chingapangitse kuti apunthwe ndikuti koyilo ya maginito imatha kufupikitsidwa kupita ku thupi la maginito.
Kuti muwone ngati pali cholumikizira cholumikizira cha maginito ndikuyesa kukana, kuchokera ku lead kapena kutsogolo kwakuda, kupita ku thupi la maginito.Khazikitsani ma multimeter pamlingo wake wapamwamba kwambiri wokana.Izi ziyenera kuwonetsa ma infinity ohms.
Moyenera muyeso uwu uyenera kupangidwa ndi "Megger mita".Mamita amtunduwu amayang'ana kukana ndi mphamvu yayikulu (nthawi zambiri 1,000 volts) yogwiritsidwa ntchito.Izi zipeza zovuta zowonongeka zowonongeka kuposa zomwe zimapezeka ndi multimeter wamba.
Kuwonongeka kwa mpweya pakati pa koyilo ndi thupi la maginito ndi vuto lalikulu ndipo nthawi zambiri zimafuna kuti koyiloyo ichotsedwe pamagetsi kuti ikonzedwe kapena kusinthidwa ndi koyilo yatsopano.
Ngati clamping yopepuka ikugwira ntchito koma kupukuta kwathunthu sichita:
Onetsetsani kuti "Angle Microswitch" ikuyenda bwino.
[Sinthani iyi imayendetsedwa ndi sikweya (kapena yozungulira) chidutswa chamkuwa chomwe chimamangiriridwa pakona yowonetsa makina.Pamene chogwiriracho chimakoka mtengo wopindika umazungulira womwe umapereka kasinthasintha kwa actuator yamkuwa.The actuator imagwiritsa ntchito microswitch mkati mwa magetsi.]
Microswitch actuator pa Model 1000E
(Zitsanzo zina zimagwiritsa ntchito mfundo yomweyi)
Actuator monga momwe amawonera mkati mwamagetsi
msonkhano.
Kokani chogwiriracho ndikulowetsamo. Muyenera kumva microswitch ikudina ON ndi KUZIMA (ngati kulibe phokoso lambiri lakumbuyo).
Ngati chosinthira sichikudina ON ndi KUZIMU ndiye pindani mtengo wopindika m'mwamba kuti cholumikizira chamkuwa chiwoneke.Tembenuzani mtengo wopindika m'mwamba ndi pansi.The actuator iyenera kuzungulira potengera mtengo wopindika (mpaka itagwira poyima).Ngati sichoncho, ndiye kuti pangafunike mphamvu yogwira:
- Pa 650E ndi 1000E mphamvu clutching akhoza ziwonjezeke pochotsa mkuwa actuator ndi kufinya anatumbula anatseka (mwachitsanzo ndi vice) pamaso reinstalling izo.
- Pa 1250E kusowa kwa mphamvu yogwirizira nthawi zambiri kumakhudzana ndi zomangira ziwiri za M8 cap-head kumapeto konse kwa shaft ya actuator osalimba.
Ngati actuator imazungulira ndikugwira Chabwino koma osadinanso microswitch ndiye kuti ingafunike kusintha.Kuti muchite izi choyamba chotsani makina opangira magetsi ndikuchotsani gulu lamagetsi.
a) Pa Model 1250E nsonga yotembenukira imatha kusinthidwa ndikutembenuza screw yomwe imadutsa pa actuator.Chomangiracho chiyenera kusinthidwa kotero kuti chosinthiracho chimadina pamene m'mphepete mwachitsulo chopindika chasuntha pafupifupi 4 mm.(Pa 650E ndi 1000E kusintha komweko kumatheka popinda mkono wa microswitch.)
b) Ngati microswitch sichikudina ON ndi OFF ngakhale kuti actuator ikugwira ntchito bwino ndiye kuti chosinthiracho chikhoza kusakanikirana mkati ndipo chiyenera kusinthidwa.
Onetsetsani kuti makinawo achotsedwa pamagetsi musanayese kukonzanso mkati.
Kusintha koyenera kwa V3:
Nambala ya RS gawo: 472-8235
Mlingo wapano: 16 amps
Chigawo cha V3
C= 'Common'
NC = 'Nthawi zambiri Kutsekedwa'
NO= 'Nthawi zambiri Otsegula'
c) Ngati makina anu ali ndi cholumikizira chothandizira, onetsetsani kuti chasinthidwa kukhala "NORMAL".(Kuthirira kopepuka kokha kudzapezeka ngati chosinthira chili pa "AUX CLAMP".)
Ngati clamping ili bwino koma ma Clampbars samamasula makina akazima:
Izi zikuwonetsa kulephera kwa reverse pulse demagnetising circuit.Choyambitsa chachikulu chingakhale chowomberedwa champhamvu cha 6.8 ohm.Yang'ananinso ma diode onse komanso kuthekera kokakamira zolumikizirana.
Njira yabwino yosinthira resistor:
Element14 gawo No. 145 7941
6.8 ohm, 10 watt mphamvu mphamvu.
Mtengo wokhazikika $1.00
Ngati makina sangapindike pepala lozama kwambiri:
a) Onetsetsani kuti ntchitoyo ili mkati mwa makina.Makamaka zindikirani kuti pa 1.6 mm (16 gauge) yopindika cholumikizira chiyenera kuyikidwa pamtengo wopindika komanso kuti m'lifupi mwake milomo ndi 30 mm.Izi zikutanthauza kuti zinthu zosachepera 30 mm ziyenera kutuluka m'mphepete mwa clampbar.(Izi zimagwira ntchito pa aluminiyamu ndi chitsulo.)
Milomo yopapatiza imatheka ngati kupindika sikuli kutalika kwa makina.
b) Komanso ngati chogwiriracho sichidzaza malo pansi pa clampbar ndiye kuti magwiridwe antchito angakhudzidwe.Kuti mupeze zotsatira zabwino nthawi zonse lembani danga pansi pa clampbar ndi zidutswa zachitsulo zofanana ndi zogwirira ntchito.(Pakuti maginito agwire bwino, chodzazacho chiyenera kukhala chitsulo ngakhale chogwiriracho sichikhala chitsulo.)
Iyi ndi njira yabwino kwambiri yogwiritsira ntchito ngati ikufunika kupanga milomo yopapatiza kwambiri pa workpiece.
