Isebenza kanjani iphampu ye-vacuum yemoto?

Indima yephampu ye-automotive vacuum: isingeniso

Uhlelo lokubhuleka ezimotweni zabagibeli kanye nezimoto ezincane ezihwebayo ikakhulukazi zisebenzisa i-hydraulic pressure njengendlela yokudlulisa.Uma iqhathaniswa ne-pneumatic braking system ekwazi ukunikeza umthombo wamandla, idinga i-booster system ukusiza umshayeli ekubhulekeni.I-vacuum brake booster system yaziwa nangokuthi i-vacuum servo brake system, i-servo brake system isekelwe ku-human hydraulic braking kanye nesethi yeminye imithombo yamandla ukuhlinzeka ngedivayisi yokuqinisa amandla okubhuleka, ukuze kusetshenziswe umuntu namandla, okungukuthi. , kokubili amandla omuntu nawenjini njengesistimu yokubhuleka yamandla ebhuleki.Ngaphansi kwezimo ezijwayelekile, ingcindezi yokuphuma kwayo ikhiqizwa ikakhulukazi isistimu ye-servo yamandla, ngakho-ke lapho isistimu ye-servo yamandla ihluleka, isengaqhutshwa uhlelo lwe-hydraulic yomuntu ukukhiqiza izinga elithile lamandla okubhuleka.

Indima yephampu ye-automotive vacuum: isimiso sokusebenza

Ngomthombo we-vacuum booster system, izimoto ezinezinjini zikaphethiloli zingakwazi ukukhiqiza umfutho we-vacuum ophezulu endaweni eningi yokufaka ngenxa yohlobo lokuthungela lwenjini, olunganikeza umthombo we-vacuum owanele wesistimu ye-vacuum booster, kuyilapho izimoto ezishayelwa. ngezinjini zikadizili, injini isebenzisa i-compression ignition CI (umjikelezo wokucindezelwa kwe-Ignition), ngakho-ke Ngaphezu kwalokho, ezinjini zokujova eziqondile zikaphethiloli (GDI), eziklanyelwe ukuhlangabezana nezidingo eziphakeme zokukhishwa, izinga elifanayo lokucindezela kwe-vacuum alikwazi ukuhlinzekwa lapho kuthathwa. maningi ukuze kuhlangatshezwane nezidingo zesistimu ye-vacuum brake booster, ngakho-ke ipompo ye-vacuum nayo iyadingeka ukuze inikeze umthombo we-vacuum.Ngakho-ke ipompo ye-vacuum nayo iyadingeka ukunikeza umthombo we-vacuum.

Nokho, mayelana nesimiso sokusebenza sephampu ye-vacuum yemoto ngizokusho lokhu, angazi ukuthi uyiqonda kangakanani, kahle ngizokunikeza lokhu namuhla ngiyabonga ngokubuka sizokubona ngokuzayo.
