MAGNABEND MATSALAR JAGORANCI HARBI
Jagorar Harbin Matsala
Mai zuwa ya shafi injinan Magnabend wanda Magnetic Engineering Pty Ltd ya yi har zuwa shekara ta 2004.
Tun bayan kare haƙƙin mallaka (mallakar Magnetic Engineering) wasu masana'antun yanzu suna kera injinan Magnabend waɗanda ƙila ba daidai suke ba.Don haka bayanin da ke ƙasa bazai yi amfani da injin ku ba ko yana iya buƙatar daidaitawa.
Hanya mafi sauƙi don gyara matsalolin wutar lantarki ita ce yin odar maye gurbin na'urar lantarki daga masana'anta.Ana ba da wannan akan tsarin musayar don haka yana da tsada sosai.
Kafin aika neman tsarin musanya kuna iya son duba waɗannan abubuwan:
Idan injin ba ya aiki kwata-kwata:
a) Bincika cewa akwai wutar lantarki a injin ta hanyar lura da hasken matukin jirgi a cikin ON/KASHE.
b) Idan wutar lantarki ta kasance amma har yanzu injin ya mutu amma yana jin zafi sosai to yankewar zafin na iya yin rauni.A wannan yanayin jira har sai injin ya huce (kimanin ½ awa) sannan a sake gwadawa.
c) Makullin farawa mai hannu biyu yana buƙatar danna maɓallin START kafin a ja hannun.Idan aka fara jan hannun da farko to injin ba zai yi aiki ba.Hakanan yana iya faruwa cewa katako mai lanƙwasa yana motsawa (ko kuma ya bumped) isasshe don sarrafa "angle microswitch" kafin a danna maɓallin START.Idan wannan ya faru a tabbata an fara tura hannun gaba ɗaya gaba ɗaya.Idan wannan matsala ce mai tsayi to yana nuna cewa mai kunnawa microswitch yana buƙatar daidaitawa (duba ƙasa).
d) Wata yuwuwar ita ce maɓallin START na iya zama kuskure.Idan kana da Model 1250E ko ya fi girma to duba idan za'a iya fara na'urar da ɗaya daga cikin madadin maɓallan START ko maɓallan ƙafa.
e) Hakanan duba haɗin nailan wanda ke haɗa tsarin lantarki tare da na'urar maganadisu.
f) Idan clamping bai yi aiki ba amma clampbar ya faɗi akan sakin maɓallin START to wannan yana nuna cewa 15 microfarad (10 µF akan 650E) capacitor yayi kuskure kuma yana buƙatar maye gurbinsa.
Idan na'urar ta busa fis na waje ko kuma ta yi tafiyar da'ira:
Mafi kusantar dalilin wannan hali shine busa gada-gyara.Mai gyara hurawa yawanci zai sami aƙalla ɗaya daga cikin diodes na ciki 4 da aka gajarta.
Ana iya bincika wannan tare da multimeter.Tare da mita akan iyakar juriya mafi ƙasƙanci bincika tsakanin kowane tashoshi biyu.Ɗayan polarity na jagororin gwajin multimeter yakamata ya nuna rashin iyaka ohms kuma polarity na juyawa yakamata ya nuna ƙaramin karatu, amma ba sifili ba.Idan kowane karatun juriya bai zama sifili ba to ana busa mai gyara kuma dole ne a maye gurbinsa.
Tabbatar cewa an cire injin ɗin daga tashar wutar lantarki kafin yin ƙoƙarin gyara na ciki.
Mai gyara gyara mai dacewa:
Lambar ɓangaren RS: 227-8794
Max na yanzu: 35 amps ci gaba,
Matsakaicin ƙarfin juyi: 1000V,
Tasha: 1/4" mai sauri-haɗa ko 'Faston'
Kimanin farashi: $12.00
Wani dalili mai yuwuwa na tatsewa shi ne cewa ana iya gajarta ƙarfin maganadisu zuwa jikin maganadisu.
Don bincika wannan cire haɗin haɗin na'urar maganadisu kuma auna juriya, daga ko dai ja ko gubar baki, zuwa jikin maganadisu.Saita multimeter zuwa iyakar juriya mafi girma.Wannan ya kamata ya nuna infinity ohms.
Da kyau wannan ma'aunin ya kamata a yi shi da "Megger meter".Irin wannan mita yana duba juriya tare da babban ƙarfin lantarki (yawanci 1,000 volts).Wannan zai sami ƙarin matsalolin rushewar rufin da dabara fiye da yadda ake iya samu tare da multimeter na yau da kullun.
Rushewar rufi tsakanin nada da jikin maganadisu babbar matsala ce kuma yawanci tana buƙatar cire coil ɗin daga jikin maganadisu don gyara ko musanyawa da sabon nada.
Idan manne haske yana aiki amma cikakken manne baya:
Duba cewa "Angle Microswitch" ana kunna shi daidai.
[Wannan maɓalli ana sarrafa shi ta wani yanki mai murabba'i (ko zagaye) na tagulla wanda ke manne da kusurwar da ke nuna hanyar.Lokacin da aka ja riƙon katakon lanƙwasa yana juyawa wanda ke ba da juyi ga mai kunna tagulla.Mai kunnawa kuma yana aiki da microswitch a cikin taron lantarki.]
Mai kunnawa Microswitch akan Model 1000E
(Sauran samfuran suna amfani da ƙa'ida ɗaya)
Mai kunnawa kamar yadda aka gani daga cikin wutar lantarki
taro.
Cire hannun waje sannan ku shiga. Ya kamata ku iya jin microswitch yana danna ON da KASHE (idan babu hayaniyar baya da yawa).
Idan mai kunnawa bai danna ON da KASHE ba to sai a lankwasa katakon lankwasa daidai sama domin a iya ganin mai kunna tagulla.Juyawa katakon lanƙwasawa sama da ƙasa.Mai kunnawa ya kamata ya juya don mayar da martani ga katako mai lanƙwasa (har sai ya kama a tsayawarsa).Idan bai yi ba to yana iya buƙatar ƙarin ƙarfi:
- A kan 650E da 1000E za a iya ƙara ƙarfin kamawa ta hanyar cire kayan aikin tagulla da matse tsaga rufaffiyar (misali tare da mataimakin) kafin sake shigar da shi.
- A kan rashin ƙarfi na 1250E yawanci yana da alaƙa da sukurori guda biyu na M8 cap-head sukurori a kowane ƙarshen mashin mai kunnawa.
Idan actuator ya juya ya kama Ok amma har yanzu bai danna microswitch ba to yana iya buƙatar daidaitawa.Don yin wannan da farko cire na'urar daga tashar wutar lantarki sannan cire panel access panel.
a) A kan Model 1250E za'a iya daidaita ma'anar kunnawa ta hanyar kunna dunƙule wanda ke wucewa ta cikin mai kunnawa.Ya kamata a gyara dunƙule kamar yadda maɓallin ke dannawa lokacin da gefen ƙasa na katako mai lanƙwasa ya motsa kusan 4 mm.(A kan 650E da 1000E ana samun daidaitattun daidaitattun ta hanyar lanƙwasa hannun microswitch.)
b) Idan microswitch bai danna ON da KASHE ba ko da yake mai kunnawa yana aiki da kyau to ana iya haɗa shi da kansa a ciki kuma yana buƙatar sauyawa.
Tabbatar cewa an cire injin ɗin daga tashar wutar lantarki kafin yin ƙoƙarin gyara na ciki.

Idan inji ba zai lanƙwasa ma'auni mai nauyi ba:
a) Duba cewa aikin yana cikin ƙayyadaddun na'ura.Musamman lura cewa don 1.6 mm (ma'auni 16) lankwasawa dole ne a sanya sandar tsawo zuwa katakon lanƙwasa kuma mafi ƙarancin faɗin leɓe shine 30 mm.Wannan yana nufin cewa aƙalla 30 mm na abu dole ne a fito da shi daga gefen lanƙwasawa na clampbar.(Wannan ya shafi duka aluminum da karfe.)
kunkuntar lebe yana yiwuwa idan lanƙwasawa ba cikakken tsayin injin ɗin ba ne.
b) Hakanan idan aikin aikin bai cika sararin samaniya a ƙarƙashin maƙalar ba to ana iya shafar aikin.Don sakamako mafi kyau koyaushe cika sararin da ke ƙarƙashin clampbar tare da guntun karfe mai kauri iri ɗaya da kayan aikin.(Don mafi kyawun clamping Magnetic yanki ya kamata ya zama karfe koda kuwa aikin ba karfe bane.)
