Mfundo yaikulu ya vacuum booster.
Chowonjezera mpweya chimagwiritsa ntchito vacuum (kupanikizika koipa) kuti chiwonjezere mphamvu yomwe dalaivala amagwiritsa ntchito pa pedal, motero chimawonjezera mphamvu ya breki. Mfundo yeniyeni yogwirira ntchito ndi iyi:
Injini ikagwira ntchito, brake booster pump imapanga vacuum mbali imodzi ya booster poyamwa mpweya, zomwe zimapangitsa kusiyana kwa kuthamanga ndi kuthamanga kwa mpweya wabwinobwino kumbali inayo. Kusiyana kwa kuthamanga kumeneku kumalola diaphragm kupita kumapeto kwa kuthamanga kochepa, motero kukankhira ndodo yokakamiza ya brake master pump.
Pakugwira ntchito, kasupe wobwezeretsa ndodo yopondereza amasunga pedal ya brake pamalo ake oyamba. Panthawiyi, valavu yoyang'anira pamalo olumikizira chubu cha vacuum ndi cholimbikitsira vacuum imatsegulidwa. Diaphragm mkati mwa cholimbikitsira imagawa chipinda chenicheni cha mpweya ndi chipinda cha mpweya chogwiritsidwa ntchito, zomwe nthawi zambiri zimasiyana ndi dziko lakunja koma zimatha kulumikizidwa kumlengalenga ndi zida ziwiri za valavu.
Woyendetsa galimoto akakanikiza pansi brake pedal, push rod action imatseka vacuum valve, pomwe air valve yomwe ili kumapeto ena imatseguka, zomwe zimathandiza kuti mpweya ulowe. Pogwiritsa ntchito mphamvu yoipa, diaphragm imakokedwa kumapeto kwa brake master pump, yomwe imayendetsa push rod ndikuwonjezera mphamvu ya mwendo.
Kapangidwe kameneka kamalola dalaivala kuwongolera kutsika kwa liwiro la galimoto mosavuta akakanikiza brake pedal, zomwe zimapangitsa kuti chitetezo cha galimoto chikhale bwino.
Kodi chowonjezera cha vacuum chosavuta kuswa?
Chothandizira cha vacuum sichosavuta kuchiwononga, bola ngati chayikidwa bwino ndikugwiritsidwa ntchito, chingagwire ntchito bwino kwa nthawi yayitali. Komabe, momwe pampu yolimbikitsira vacuum imagwirira ntchito ingakhudzidwe ndi zinthu zingapo, kuphatikizapo momwe galimotoyo imagwiritsidwira ntchito, zinthu zachilengedwe, komanso ngati kukonza ndi kukonza kumachitika nthawi zonse.
Kugwiritsa ntchito bwino ndi kukonza galimoto: Bola galimoto nthawi zambiri imakhala pamalo ovuta kwambiri (monga kutentha kwambiri, chinyezi chambiri kapena kugunda kwambiri), kapena galimotoyo siisamalidwa nthawi zonse, mapampu owonjezera mphamvu amatha kukhala ndi mavuto. Chifukwa chake, kuyika bwino, kugwiritsa ntchito bwino komanso kusamalira nthawi zonse ndikofunikira kwambiri kuti chowonjezera mphamvu chigwire ntchito bwino.
Zinthu Zachilengedwe: Mphamvu ya chowonjezera mpweya woipa imakhudzidwa kwambiri ndi zinthu zachilengedwe, monga kusowa kwa mpweya woipa chifukwa choyendetsa galimoto pamalo okwera, komanso kusowa kwa mpweya woipa chifukwa cha nyengo yozizira. Zinthu zachilengedwe izi ziyenera kuganiziridwa popanga ndi kupanga galimoto, ndipo pakugwiritsa ntchito galimoto tsiku ndi tsiku, mwiniwakeyo ayeneranso kukhala ndi chidziwitso chodziyesa kuti athetse mavutowa.
Zolakwika Zofala: Zolakwika zofala zimaphatikizapo kuwonongeka kwa vacuum booster check valve, zomwe zingayambitse kutsekedwa kosamasuka, mabuleki olimba, komanso liwiro losakhazikika lopanda ntchito potseka mabuleki. Kuphatikiza apo, vuto la kutayikira kwa mafuta ndi vuto lofala, pamene kutayikira kwa mafuta a brake master pump, kudzera kumapeto kwa chisindikizo cha mafuta kulowa mkati mwa chisindikizo, zomwe zimapangitsa kuti diaphragm isinthe, chisindikizocho sichili chokhwima, mphamvu imatsika.
Pofuna kusunga bwino ntchito ya cholimbikitsira mpweya chopanda mpweya, akulangizidwa kuti mwiniwake aziyang'ana ndikusunga makina a mabuleki panthawi yake akamagwiritsa ntchito galimotoyo nthawi zonse. Kuphatikiza apo, cholimbikitsira mpweya chopanda mpweya ndi mtundu wa cholimbikitsira mpweya cholondola kwambiri komanso chosavuta kugwiritsa ntchito, chomwe chiyenera kutsatiridwa mosamala ndi malamulo a mafuta opaka, kuwona ngati ntchito ndi mafuta opaka mpweya ndi abwinobwino, ndikuwona ngati chotenthetsera mpweya chili ndi vuto lotayikira. Ngati cholimbikitsira mpweya chopanda mpweya sichinagwiritsidwe ntchito kwa nthawi yayitali, sichiyenera kugwira ntchito mokwanira nthawi yomweyo chikagwiritsidwanso ntchito.
Chowonjezera cha vacuum chasweka
Kagwiridwe ka ntchito ka vacuum booster kosweka makamaka kumaphatikizapo kusagwira bwino ntchito kwa mabuleki kapena kusagwira bwino ntchito kwa mabuleki, kubwerera pang'onopang'ono kapena kusagwira bwino ntchito kwa mabuleki, phokoso losazolowereka limamveka mutaponda mabuleki, komwe mabuleki amatembenukira kapena kugwedezeka, komanso mabuleki amamva ngati ofewa. Zizindikiro izi zikusonyeza kuti vacuum booster ikhoza kukhala ndi vuto, monga kutuluka kwa mpweya kapena kuwonongeka, ndipo iyenera kuyang'aniridwa ndikukonzedwa nthawi yake kuti zitsimikizire kuti kuyendetsa bwino.
Kufunika kwa chowonjezera mpweya chopanda mpweya ndikuti chimathandiza dalaivala kulimbitsa mphamvu ya brake ndikuchepetsa mphamvu ya ntchito ya brake ya dalaivala, motero kumawonjezera magwiridwe antchito ndi chitetezo cha brake. Chowonjezera mpweya chopanda mpweya chikalephera, monga kutulutsa mpweya, chingayambitse kuchepa kwakukulu kwa magwiridwe antchito a brake, kapena kutayika kwathunthu kwa mphamvu ya brake, zomwe zimawonjezera kwambiri chiopsezo choyendetsa.
Kutuluka kwa mpweya wowonjezera mpweya wa vacuum booster kungaphatikizepo kusagwira bwino ntchito kwa mabuleki, kubwerera pang'onopang'ono kapena kusabwerera konse kwa mabuleki, komanso phokoso losazolowereka lingamveke pambuyo poti mabuleki akanikiza. Ngati zizindikirozi zapezeka, tikukulimbikitsani kuti muyang'ane ndikukonza vacuum booster nthawi yomweyo.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
