Kunna wutar lantarki na akwatin sarrafawa na saitin janareta na Cummins. Lokacin da akwai sauri guda biyu, kintsattse da ƙananan sautuna, tsarin sarrafa saurin ya zama na al'ada; Idan babu sauti, yana iya zama cewa hukumar sarrafa saurin ba ta da fitarwa ko kuma mai kunnawa ya yi tsatsa ya makale.
(1) Gano kuskuren allon kulawa
Lokacin da wutar lantarki ke kunne, auna ƙarfin lantarki na DC na a23-a22 akan babban farantin gindi. Idan ƙarfin lantarki ya fi 12V, yana nuna cewa fitarwa na allon sarrafawa al'ada ce. Idan u = 0, auna ƙarfin lantarki a maki B da C na soket na allon sarrafa saurin. Idan u> 12V, allon sarrafawa al'ada ce. Duba ko da'irar da aka buga na babban farantin tushe a buɗe yake; In ba haka ba, idan hukumar sarrafa saurin ta gaza, maye gurbin allon sarrafawa.
(2) Gano kuskuren actuator
Juriya na na'urar kunnawa shine 7-loq kuma inductance shine 120mh. An keɓe shi daga ƙasa. Ana iya yin hukunci akan yanayin lantarki ta hanyar auna ma'auni daban-daban; Lokacin da yake da wuya a yanke hukunci game da yanayin inji na saitin aiki, ana iya haɗa wutar lantarki kai tsaye na 12V na waje, wanda za'a iya yanke hukunci ta yanayin sauti lokacin da yake kunne da kashewa. Lokacin da aka katange katin da tsatsa, ana iya cire mai kunnawa tare da kayan aiki na musamman don tsaftacewa da nika (ba a yarda da abrasive karfe) don gyarawa. Lokacin da ba za a iya gyara shi ba, sai a canza shi.
Lokacin da allon sarrafawa ba zai iya sarrafa abin da aka saba da shi ba daga sarrafawa ba, yana faruwa ne sakamakon ɗigon mai saboda lalacewa da ƙarin sharewar injin kunnawa. Lokacin da aka saita saurin aiki a n < 600r / min kuma saurin ya tashi zuwa 900-l700r / min, yawanci ana kiran shi ba gudu mara amfani ba. Lokacin da yanayin tafiyar da saitin ya kasance n = l500r / ruwan sama, ainihin gudun yana ƙasa da l700r / min kuma tsarin saurin ba shi da inganci, wanda ke haifar da dalilan da ke sama. Saboda saitin janareta na diesel yana aiki a kusan l500r / ruwan sama, saurin rashin aiki yana da ɗan tasiri, kuma ana iya ci gaba da amfani da mai kunnawa; Lokacin da ɗigon mai ya yi tsanani kuma saurin ya yi yawa, amma lokacin da ake ɗora Lo% - L5%, saurin gudu zai iya kaiwa yanayin sarrafawa na al'ada, kuma ana iya ci gaba da amfani da mai kunnawa; Idan saurin ya karu da yawa har sai ya tsaya saboda kariyar da ya wuce kima, maye gurbin mai kunnawa.
(3) Gano firikwensin saurin gudu
Lokacin da siginar firikwensin saurin ya yi ƙarfi sosai, saurin tsarin sarrafa saurin yana da ƙarfi. Lokacin da siginar ya yi rauni sosai kuma babu sigina, yana da sauƙi don sarrafa gazawar da haifar da wuce gona da iri. Juriya na na'urar firikwensin saurin kusan 300 Ω, kuma ƙarfin fitarwa shine 1.5-20vac yayin aiki. In ba haka ba, za a maye gurbin firikwensin idan akwai kuskure. Daidaita ƙarfin siginar sauri na firikwensin saurin: dunƙule firikwensin a ciki, ƙara ƙara ƙarshen gear ɗin tashi, sannan fita don 1 / 2-3 / 4 juya kuma kulle shi. A wannan lokacin, tazarar da ke tsakanin saman firikwensin da titin haƙoran haƙora ya kai kusan 0.7mm-1.1mm. Juyi a cikin ƙarfin fitarwa yana ƙaruwa kuma ƙarfin fitarwa yana raguwa.
