Ukuhlaziywa kwamaphutha okuvamile

1, Ngemuva kokuthi kuvulwe ukunikezwa kwamandla, iphaneli yokulawula ikhombisa ngokujwayelekile, isiphephetha-moya sokupholisa sisebenza ngokujwayelekile, futhi i-relay emaphakathi isebenza ngenkathii-centrifugeayisebenzi uma inkinobho yokuqala icindezelwa.Ngokusho kokuhlaziywa kwe-fault phenomenon, ingxenye yokuphakelwa kwamandla kanye nengxenye yokulawula kufanele ibe yinto evamile, futhi iphutha kufanele libe emgqeni osuka ebhodini lokulawula ukuya emotweni, ibhulashi le-carbon kanye ne-motor.Vula i-centrifuge, sebenzisa i-multimeter ukukala ukuqhutshwa komugqa kusuka ebhodini lokulawula kuya kubhulashi le-carbon, bese ukala ibhulashi le-carbon ku-motor rotor ayiqhubeki, qaphela ngokucophelela ukuthintana okungalungile phakathi kwe-carbon brush kanye ne-rotor motor, susa. ibhulashi le-carbon futhi uthole ukuthi isikhathi sokusebenzisa side kakhulu, sifushane kakhulu sibangelwa.Faka esikhundleni ibhulashi lekhabhoni elisha, ukuxazulula inkinga.Lokhu kwehluleka kuwukwehluleka okuvamile kwe-centrifuge, futhi ibhulashi lekhabhoni kufanele lishintshwe njalo ukuze kugwenywe ukwehluleka okungenhla.

2, Ngemuva kokuthi kuvulwe ukunikezwa kwamandla, iphaneli yokulawula ikhombisa ngokujwayelekile, isiphephetha-moya sokupholisa sisebenza ngokujwayelekile, futhi i-relay emaphakathi ayisebenzi futhii-centrifugeayisebenzi uma inkinobho yokuqala icindezelwa.Ngokusho kokuhlaziywa kwe-fault phenomenon, ingxenye yokuhlinzeka amandla kufanele ibe yinto evamile, futhi iphutha kufanele libe ebhodini lokulawula kanye nomugqa oya kumotho, ibhulashi le-carbon kanye ne-motor.Vula i-centrifuge, sebenzisa i-multimeter ukukala ukuqhutshwa komugqa ukusuka ebhodini lokulawula ukuya kubhulashi lekhabhoni, bese ukala ibhulashi lekhabhoni ku-rotor ye-motor nakho kuyasebenza, futhi ukukala ikhoyili yemoto kuyinto evamile.Ngemuva kokuqala, sebenzisa i-multimeter ukukala ukuphuma kwe-non-voltage yocingo kusuka ebhodini lokulawula kuya ku-motor, ungahlulela ukuthi iphutha kufanele libe ebhodini lokulawula, lapho i-relay ephakathi ingasebenzi, iphutha kufanele libe. kumjikelezo wokulawula we-control intermediate relay, futhi uyisuse ngayinye ngayinye, futhi uthole ukuthi ukuhlukana kwe-C9013 triode ebhodini lokulawula, kanye ne-C9013 triode entsha kubi kakhulu.

3, Ngemuva kokuthi amandla evuliwe, iphaneli yokulawula iboniswa ngokujwayelekile, futhii-centrifugeisebenza ngokujwayelekile uma inkinobho yokuqala icindezelwa.Nokho, lapho iswishi yokumisa icindezelwa, i-centrifuge ayinakho ukusabela futhi ayikwazi ukuyeka ukusebenza.Ngokusho kokuhlaziywa kwezenzakalo zephutha, iphutha kufanele libe sengxenyeni yokulawula ukumisa yesifunda sokulawula, okuhlanganisa ukushintshwa kokumisa, ibhodi lokulawula amandla kanye nebhodi lokulawula isikhathi.Vula i-centrifuge, sebenzisa i-multimeter ukuhlola ukushintshwa kokumisa, futhi kuvamile;Ngemuva kokuqala, ukuphuma kwesignali kusuka ebhodini lokulawula amandla okulinganisa kuya ebhodini lokulawula isikhathi kuyi-AC 16V evamile, iphutha kufanele libe ebhodini lokulawula isikhathi, futhi ibhodi lokulawula isikhathi alikwazi ukwenza umsebenzi wokumisa ngemva kokuthola isignali yokumisa.Khipha ngayinye ngayinye, etholakala ebhodini lokulawula i-timer C9013 triode kanye nemodeli engu-16V, ukuhlukana kwe-capacitor engu-470μF, i-triode entsha embi kakhulu ne-capacitor, ukuxazulula inkinga.

I-4, Ngemuva kokuthi amandla evuliwe, iphaneli yokulawula ibonakala ngokujwayelekile, futhii-centrifugeisebenza ngokujwayelekile uma inkinobho yokuqala icindezelwa.Kodwa lapho iswishi yokumisa icindezelwa, i-centrifuge ayiyeki ukusebenza ngokushesha, kodwa ijikeleza isikhathi eside ngaphambi kokuma kancane.Ngokusho kokuhlaziywa kwe-fault phenomenon, iphutha kufanele libe engxenyeni yokulawula yengxenye yokulawula ibhuleki, ingxenye yokulawula ibhuleki ifaka imodeli: i-WJ176-12V edluliselwe phakathi, ukumelana namabhuleki R: 20-30Ω, imodeli: i-silicon ye-KBPC50A10M inqwaba nocingo.Vula i-centrifuge futhi usebenzise i-multimeter ukukala ukumelana namabhuleki, ukudluliselwa okuphakathi nendawo kanye nocingo.Ngemva kokuqala i-centrifuge, cindezela inkinobho yokumisa futhi usebenzise i-multimeter ukukala amakhona angu-4 enqwaba ye-silicon ngokufaka kwe-AC 12V futhi akukho okuphumayo kwe-DC 12V.Yahlulela ukuthi inqwaba ye-silicon yimbi bese uyishintsha ufake entsha.
