Vula iswishi yamandla yebhokisi lokulawula lesethi yejeneretha ye-Cummins. Uma kunemisindo emibili esheshayo, esheshayo nencane, isistimu yokulawula isivinini ijwayelekile; Uma kungekho msindo, kungenzeka ukuthi ibhodi lokulawula isivinini alinawo umphumela noma i-actuator igqwalile futhi ibambekile.
(1) Ukutholwa kwephutha kwebhodi lokulawula
Uma iswishi yamandla ivuliwe, kala i-voltage ye-DC ye-a23-a22 ku-base plate enkulu. Uma i-voltage iphakeme kune-12V, ibonisa ukuthi ukuphuma kwebhodi lokulawula kuyinto evamile. Uma u = 0, linganisa i-voltage kumaphoyinti B no-C wesokhethi yebhodi lokulawula isivinini. Uma u> 12V, ibhodi lokulawula livamile. Hlola ukuthi isifunda esiphrintiwe se-base plate sivuliwe yini; Uma kungenjalo, uma ibhodi lokulawula isivinini lihluleka, shintsha ibhodi lokulawula.
(2) Ukutholwa kwephutha kwe-actuator
Ukumelana nekhoyili ye-actuator kungu-7-loq futhi inductance ingu-120mh. Ivikelwe phansi. Isimo sikagesi singahlulelwa ngokulinganisa okumile kwemingcele ehlukahlukene; Uma kunzima ukwahlulela isimo semishini yesethi yokusebenza, ukunikezwa kwamandla okuqondile kwangaphandle kwe-12V kungaxhunywa, okungahlulelwa ngesimo somsindo lapho ivuliwe futhi ivaliwe. Uma ikhadi livinjiwe futhi ligqwalile, i-actuator ingasuswa ngamathuluzi akhethekile okuhlanza nokugaya (i-metal abrasive ayivunyelwe) ukulungisa. Uma ingenakulungiseka, izoshintshwa.
Lapho ibhodi lokulawula lingakwazi ukulawula ukuphuma okuvamile ngaphandle kokulawula, kubangelwa ukuvuza kwamafutha ngenxa yokuguga nokwanda kokuvunyelwa kwe-actuator. Uma ijubane lokungenzi lutho lisethwe ku-n <600r / min futhi ijubane likhuphukela ku-900-l700r / min, ngokuvamile libizwa ngokuthi akukho sivinini sokungenzi lutho. Uma isimo sokugijima esimisiwe singu-n = l500r / imvula, isivinini sangempela singaphansi kwe-l700r / min futhi ukulawulwa kwesivinini akuvumelekile, okubangelwa izizathu ezingenhla. Ngenxa yokuthi isethi yejeneretha ye-diesel isebenza cishe ku-l500r / imvula, isivinini sokungenzi lutho sinomthelela omncane, futhi i-actuator ingaqhubeka nokusetshenziswa; Uma ukuvuza kwamafutha kungathí sina futhi isivinini siphezulu kakhulu, kodwa uma ulayisha i-Lo% - L5%, ukwehla kwejubane kungafinyelela esimweni sokulawula esivamile, futhi i-actuator ingaqhubeka nokusetshenziswa; Uma ijubane likhuphuka kakhulu lize lime ngenxa yokuvikela isivinini, buyisela i-actuator.
(3) Ukutholwa kwenzwa yesivinini
Uma isignali yenzwa yesivinini iqine kakhulu, isivinini sesistimu yokulawula isivinini asizinzile. Uma isignali ibuthakathaka kakhulu futhi ingekho isignali, kulula ukulawula ukwehluleka futhi kubangele isivinini esikhulu. Ukumelana nekhoyili yenzwa yesivinini cishe ku-300 Ω, kanti i-voltage ephumayo ingu-1.5-20vac ngesikhathi sokusebenza. Uma kungenjalo, inzwa izoshintshwa uma kwenzeka iphutha. Ukulungiswa kwamandla esignali yesivinini senzwa yesivinini: faka inzwa phakathi, qinisa isiphetho segiya le-flywheel, bese uphuma ngokujika okungu-1 / 2-3 / 4 bese uyikhiya. Ngalesi sikhathi, igebe phakathi kwengaphezulu lenzwa kanye nethiphu yezinyo le-flywheel licishe libe ngu-0.7mm-1.1mm. I-spin ku-voltage ephumayo iyakhuphuka futhi i-spin out output voltage iyehla.
