UMHLAHLANDLELA WOKUDUTSHULWA KWE-MAGNABEND
Umhlahlandlela Wokuthwebula Izinkinga
Lokhu okulandelayo kuyasebenza emishinini ye-Magnabend eyenziwe yi-Magnetic Engineering Pty Ltd kuze kube cishe unyaka ka-2004.
Kusukela ekuphelelweni kwesikhathi kwamalungelo obunikazi (aphethwe yiMagnetic Engineering) abanye abakhiqizi manje benza imishini yeMagnabend okungenzeka ingafani ncamashi.Ngakho-ke imininingwane engezansi ingase ingasebenzi emshinini wakho noma ingase idinge ukushintshwa.
Indlela elula yokulungisa izinkinga zikagesi uku-oda imojula kagesi eshintshwayo kumenzi.Lokhu kunikezwa ngokwesisekelo sokushintshana ngakho-ke kunentengo ephusile.
Ngaphambi kokuthumela imojuli yokushintshisana ungase uthande ukuhlola okulandelayo:
Uma umshini ungasebenzi nhlobo:
a) Hlola ukuthi amandla akhona emshinini ngokubheka ukukhanya komshayeli eswishini YOKUVAKA/CIMILE.
b) Uma amandla ekhona kodwa umshini usafile kodwa uzizwa ushisa kakhulu khona-ke i-thermal cut-out kungenzeka ukuthi ikhubekile.Kulokhu linda kuze kuphole umshini (cishe u-½ ihora) bese uzama futhi.
c) I-interlock yokuqala yezandla ezimbili idinga ukuthi inkinobho ethi START icindezelwe ngaphambi kokuthi isibambo sidonswe.Uma isibambo sidonswa kuqala umshini ngeke usebenze.Futhi kungase kwenzeke ukuthi i-beam egobayo inyakaze (noma ishaywe) ngokwanele ukusebenzisa "i-angle microswitch" ngaphambi kokuba inkinobho ethi START icindezelwe.Uma lokhu kwenzeka qiniseka ukuthi isibambo sidudulwa ngokugcwele kuqala.Uma lokhu kuyinkinga eqhubekayo kusho ukuthi i-microswitch actuator idinga ukulungiswa (bona ngezansi).
d) Okunye okungenzeka ukuthi inkinobho ethi START ingase ibe nephutha.Uma une-Model 1250E noma enkulu, bheka ukuthi umshini ungaqalwa yini ngenye yezinkinobho zokuthi START noma i-footswitch.
e) Futhi hlola isixhumi senayiloni esixhuma imojuli kagesi nekhoyili kazibuthe.
f) Uma i-clampbar ingasebenzi kodwa i-clampbar igqekeza ekukhishweni kwenkinobho ethi START lapho lokhu kukhombisa ukuthi i-15 microfarad (10 µF ku-650E) capacitor inephutha futhi izodinga ukushintshwa.
Uma umshini uphephetha ama-fuse angaphandle noma ama-circuit breaker:
Imbangela okungenzeka kakhulu yalokhu kuziphatha isilungisi sebhuloho esiphethiwe.Isilungisi esivuthelwe umoya ngokuvamile sizoba nesifinyezo sokungenani ngeyodwa yama-diode angu-4 angaphakathi.
Lokhu kungahlolwa nge-multimeter.Ngemitha kububanzi bayo obuphansi bokumelana hlola phakathi kwepheya ngalinye lamatheminali.I-polarity eyodwa yokuhlolwa kwe-multimeter kufanele ibonise i-infinity ohms futhi i-polarity ehlehlisiwe kufanele ibonise ukufundwa okuphansi, kodwa hhayi uziro.Uma noma yikuphi ukufundwa kokumelana kunguziro khona-ke isilungisisi siyashaywa futhi kufanele sishintshwe.
Qiniseka ukuthi umshini ukhishiwe esitokisini sikagesi ngaphambi kokuzama ukulungisa kwangaphakathi.
Isilungisisi esifanelekayo:
Inombolo yezingxenye ze-RS: 227-8794
Ubuningi bamanje: 35 amps okuqhubekayo,
I-Max reverse voltage: 1000 Volts,
Amatheminali: 1/4" xhuma ngokushesha noma 'Faston'
Intengo cishe: $12.00
Okunye okungaba imbangela yokukhubeka ukuthi ikhoyili kazibuthe ingase ibe mfushane kumzimba kazibuthe.
Ukuhlola lokhu kukhipha isixhumi sekhoyili kazibuthe futhi ulinganise ukumelana, ukusuka kumthofu obomvu noma omnyama, kuya emzimbeni kazibuthe.Setha i-multimeter ebangeni layo eliphakeme kakhulu lokuyeka.Lokhu kufanele kubonise i-infinity ohms.
Ngokufanelekile lesi silinganiso kufanele senziwe "ngemitha ye-Megger".Lolu hlobo lwemitha luhlola ukumelana ne-voltage ephezulu (imvamisa engu-1,000 volts) esetshenzisiwe.Lokhu kuzothola izinkinga ezicashile zokuqhekeka kwe-insulation kunezingatholakala nge-multimeter evamile.
Ukwehlukana kwe-insulation phakathi kwekhoyili nomzimba kazibuthe kuyinkinga enkulu futhi ngokuvamile kungadinga ukuthi ikhoyili ikhishwe emzimbeni kazibuthe ukuze ilungiswe noma kufakwe ikhoyili entsha.
Uma i-clamping yokukhanya isebenza kodwa i-clamping egcwele akwenzi:
Hlola ukuthi i-"Angle Microswitch" icushwe ngendlela efanele yini.
[Le swishi isetshenziswa ucezu lwethusi oluyisikwele (noma oluyindilinga) olunamathiselwe kwi-engeli ekhombisa indlela.Uma isibambo sidonswa ugongolo olugobile luyazungeza okunikeza ukuzungezisa ku-actuator yethusi.I-actuator yona isebenzisa i-microswitch ngaphakathi kwendawo kagesi.]
I-Actuator ye-Microswitch ku-Model 1000E
(Amanye amamodeli asebenzisa isimiso esifanayo)
I-Actuator njengoba ibonakala ngaphakathi kugesi
umhlangano.
Donsela isibambo usikhiphe bese usifaka. Kufanele ukwazi ukuzwa i-microswitch ichofoza VULA futhi IVALIWE (inqobo nje uma kungekho msindo omningi wangemuva).
Uma iswishi ingachofozi okuthi VULA futhi IVALIWE shwiba i-beam egobayo phezulu ukuze i-actuator yethusi ibonakale.Zungezisa i-beam yokugoba phezulu naphansi.I-actuator kufanele ijikelezise ekuphenduleni i-beam egobayo (ize ibambe ezitobhini zayo).Uma ingakwenzi lokho kungase kudinge amandla amaningi okubamba:
- Ku-650E kanye no-1000E amandla okubamba angandiswa ngokukhipha i-actuator yethusi futhi ucindezele umkeke uvaleke (isb nge-vice) ngaphambi kokuwufaka kabusha.
- Ku-1250E ukuntuleka kwamandla okubamba ngokuvamile kuhlobene nezikulufu ezimbili ze-cap-head M8 kunoma imuphi umkhawulo we-actuator shaft engaqinile.
Uma i-actuator iphenduka futhi ibambe okuthi KULUNGILE kodwa ingachofozi i-microswitch khona-ke ingase idinge ukulungiswa.Ukwenza lokhu qala ukhiphe umshini endaweni yokukhipha amandla bese ukhipha iphaneli yokufinyelela kagesi.
a) Kumodeli 1250E indawo yokuvula ingalungiswa ngokuphendula isikulufu esidlula ku-actuator.Isikulufu kufanele silungiswe ngendlela yokuthi iswishi ichofoze lapho unqenqema olungezansi lwe-beam egobayo lunyakaze cishe ngo-4 mm.(Ku-650E naku-1000E ukulungiswa okufanayo kufinyelelwa ngokugoba ingalo ye-microswitch.)
b) Uma i-microswitch ingachofozi VULA futhi IVALIWE nakuba i-actuator isebenza kahle khona-ke iswishi ngokwayo ingase ihlanganiswe ngaphakathi futhi izodinga ukushintshwa.
Qiniseka ukuthi umshini ukhishiwe esitokisini sikagesi ngaphambi kokuzama ukulungisa kwangaphakathi.
Ukushintshwa okufanelekile kwe-V3:
Inombolo yengxenye ye-RS: 472-8235
Isilinganiso samanje: 16 amps
V3 Isekhethi
C= 'Common'
NC= 'Kuvalwe Ngokujwayelekile'
NO= 'Ngokujwayelekile Kuvulwa'
c) Uma umshini wakho ufakelwe iswishi eyi-axiliary qiniseka ukuthi ishintshelwe endaweni ethi "NORMAL".(Ukubamba ukukhanya kuphela okuzotholakala uma iswishi isendaweni ethi "AUX CLAMP".)
Uma i-clamping Kulungile kodwa ama-Clampbars awakhululi lapho umshini UVALA:
Lokhu kubonisa ukwehluleka kwesekethe ye-reverse pulse demagnetising.Isizathu esingenzeka kakhulu kungaba isithako samandla esingu-6.8 ohm esiphethiwe.Futhi hlola wonke ama-diode kanye nethuba lokunamathisela oxhumana nabo ku-relay.
I-resistor efanelekile yokubuyisela:
Element14 ingxenye No. 145 7941
6.8 ohm, 10 watt amandla amandla.
Izindleko ezijwayelekile $1.00
Uma umshini ungeke ugobe ishidi lokulinganisa elisindayo:
a) Hlola ukuthi umsebenzi ungaphakathi kwemininingwane yomshini.Ikakhulukazi, yazi ukuthi ku-1.6 mm (igeji engu-16) yokugoba ibha yokwelulwa kufanele ifakwe ku-beam egobayo nokuthi ububanzi bezindebe obuncane bungama-30 mm.Lokhu kusho ukuthi okungenani u-30 mm wezinto kufanele ziphume onqenqemeni olugobile lwe-clampbar.(Lokhu kusebenza kukho kokubili i-aluminium nensimbi.)
Izindebe ezincanyana zingenzeka uma ukugoba kungebona ubude obugcwele bomshini.
b) Futhi uma i-workpiece ingasigcwalisi isikhala ngaphansi kwe-clampbar ukusebenza kungase kuphazamiseke.Ukuze uthole imiphumela engcono kakhulu hlala ugcwalisa isikhala ngaphansi kwe-clampbar ngocezu lwensimbi olulahliwe oluwugqinsi olufanayo nocezu lokusebenza.(Ukuze uthole i-clamping kazibuthe engcono kakhulu ucezu lokugcwalisa kufanele lube yinsimbi noma ngabe ucezu lokusebenza kungeyona insimbi.)
Lena futhi indlela engcono kakhulu ongayisebenzisa uma kudingekile ukwenza udebe oluncane kakhulu endaweni yokusebenza.
