Urhuluneli we-elektronikiSisixhobo sokulawula isantya sejenereyitha, esisetyenziswa kakhulu ekupakisheni, ekuprinteni, kwi-elektroniki, kwizixhobo, kwizixhobo zonyango nakwezinye iimboni njengesixhobo sokulawula isantya, ngokomqondiso wombane owamkelekileyo, ngokusebenzisa isilawuli kunye ne-actuator ukutshintsha ubungakanani bepompo yokufaka ipetroli, ukuze injini yedizili isebenze ngesantya esizinzileyo. Oku kulandelayo kukukhokelela ekufundeni ulwakhiwo kunye nomgaqo wokusebenza we-governor ye-elektroniki.
I-electronic governor kwisakhiwo kunye nomgaqo wolawulo yahluke kakhulu kwi-mechanical governor, yisantya kunye (okanye) utshintsho lomthwalo ngendlela yezibonakaliso ze-elektroniki ezidluliselwa kwiyunithi yokulawula, kwaye isignali ye-voltage (yangoku) ebekweyo ithelekiswa nemveliso yesignali ye-elektroniki kwi-actuator, isenzo se-actuator sitsala i-oyile supply rack ukuze igcwalise okanye inciphise ioyile, Ukufezekisa injongo yokulungisa ngokukhawuleza isantya senjini. I-electronic governor ithatha indawo ye-flyweight ejikelezayo kunye nezinye izakhiwo kwi-mechanical governor ngolawulo lwesignali yombane, ngaphandle kokusebenzisa indlela ye-mechanical, isenzo sinovakalelo, isantya sempendulo siyakhawuleza, kwaye iiparameter eziguqukayo nezizinzileyo zichanekile kakhulu; I-electronic governor akukho ndlela ye-governor drive, incinci ngobukhulu, kulula ukuyifaka, kulula ukuyifezekisa ulawulo oluzenzekelayo.
Kukho ii-electronic governors ezimbini eziqhelekileyo: i-single pulse electronic governor kunye ne-double pulse electronic governor. I-monopulse electronic governor isebenzisa isignali ye-speed pulse ukulungisa umbane. I-double pulse electronic governor sisantya kunye nomthwalo wesignali ezimbini ze-monopulse ezibekwe phezulu ukulungisa umbane. I-double pulse electronic governor inokulungisa umbane ngaphambi kokuba umthwalo utshintshe kwaye isantya asitshintshanga, kwaye ukuchaneka kokulungiswa kwayo kuphezulu kune-single pulse electronic governor, kwaye inokuqinisekisa uzinzo lwefrikhwensi yombane.
1- I-Actuator 2- Injini yedizili, isenzi sesantya esi-3, 4- umthwalo wedizili, isenzi semithwalo esi-5, 6- Iyunithi yokulawula isantya, i-potentiometer yokuseta isantya esi-7
Ulwakhiwo olusisiseko lwe-double pulse electronic governor luboniswe kumfanekiso. Ngokuyintloko yenziwe yi-actuator, i-speed sensor, i-load sensor kunye neyunithi yokulawula isantya. I-Magnetoelectric speed sensor isetyenziselwa ukujonga utshintsho lwesantya senjini yedizili kunye nokuvelisa i-AC voltage output ngokulinganayo. I-load sensor isetyenziselwa ukubona utshintsho lweinjini yediziliukulayisha kwaye uyiguqule ibe yi-DC voltage output ngokulinganayo. Iyunithi yokulawula isantya yintloko ye-electronic governor, eyamkela isignali ye-output voltage evela kwi-speed sensor kunye ne-load sensor, iyiguqule ibe yi-DC voltage elinganayo kwaye iyithelekise ne-speed setting voltage, kwaye ithumela umahluko emva kokuthelekiswa ne-actuator njengomqondiso wolawulo. Ngokwesignali yokulawula ye-actuator, indlela yokulawula ioyile yenjini yedizili itsalwa ngombane (hydraulic, pneumatic) ukuze igcwalise okanye inciphise ioyile.
Ukuba umthwalo wenjini yedizili unyuka ngequbuliso, i-output voltage ye-load sensor iyatshintsha kuqala, kwaye i-output voltage ye-speed sensor nayo iyatshintsha ngokufanelekileyo (amaxabiso onke ayancipha). Ezi signali zimbini ze-pulse ezincitshisiweyo zithelekiswa ne-set speed voltage kwiyunithi yokulawula isantya (ixabiso lesignali elibi le-sensor lingaphantsi kwexabiso lesignali elilungileyo le-set speed voltage), kwaye isignali ye-positive voltage yi-output, kwaye i-output axial refueling direction ijikeleziswa kwi-actuator ukwandisa umbane we-cycle fuel we-injini yedizili.
Ngokwahlukileyo koko, ukuba umthwalo wenjini yedizili uyancipha ngequbuliso, i-output voltage ye-load sensor iyatshintsha kuqala, kwaye i-output voltage ye-speed sensor nayo iyatshintsha ngokufanelekileyo (amaxabiso ayanyuka). Izibonakaliso ezimbini eziphezulu ze-pulse zithelekiswa ne-set speed voltage kwiyunithi yokulawula isantya. Ngeli xesha, ixabiso le-negative signal ye-sensor likhulu kunexabiso le-positive signal ye-set speed voltage. I-negative voltage signal yeyunithi yokulawula isantya yi-output, kwaye i-output axial oil reduction direction ijikeleziswa kwi-actuator ukunciphisa ukunikezelwa kweoyile yomjikelo we-injini yedizili.
Oku kungasentla ngumgaqo wokusebenza werhuluneli ye-elektroniki yeiseti yejenereyitha yedizili.
