Pampu ya vacuum - kodi pampu ya vacuum imagwira ntchito bwanji mu injini za dizilo?

Kawirikawiri mapampu a vacuum amagwirizanitsidwa ndi injini za dizilo, koma nthawi zina amapezekanso mu injini za mafuta. Kodi pampu ya vacuum ndi chiyani? Mwa kuyankhula kwina, ndi pampu ya vacuum yomwe ntchito yake ndi kupanga mphamvu yolakwika. Kuti mugwiritse ntchito moyenera, ndikofunikira kwambiri:

• injini;
• dongosolo brake;
• turbocharger;
• HORN.

Onani zovuta zapampu ndikuwerenga momwe mungakonzere!

Vacuum - pampu iyi ndi ya chiyani ndipo ikufunika kuti?

Ndikofunikira kwambiri kumvetsetsa mfundo yogwiritsira ntchito injini yoyaka mkati mopanda ntchito. Mu mayunitsi ndi injini ya petulo nthawi zambiri palibe vacuum, chifukwa vacuum mu zobweza zambiri amatha kupanga zofunika zofunika kusunga rpm. Izi sizikugwira ntchito ku injini za dizilo zopanda throttleless. Kumeneko, kuyatsa kwachabechabe komanso kugwira ntchito kwa, mwachitsanzo, ma brake system ndizotheka chifukwa cha vacuum pump. 

N'chifukwa chiyani pampu vacuum ndi chinthu chofunika kwambiri pa dongosolo?

Kodi pampu ya vacuum imagwiritsidwa ntchito chiyani? Zimapereka zikhalidwe zoyambira kuti zisunge zinthu zomwe zikuyenda. Kuphatikiza apo, mu injini zokhala ndi ma jekeseni a unit, vacuum imapangitsanso kuwonjezereka kwamafuta. Chifukwa chake, m'mainjini awa, kupsinjika kwa pampu ya vacuum kumawonekera kwambiri pomwe chikhalidwe chantchito chikuwonongeka.

Pampu ya vacuum - imachita chiyani?

Kuphatikiza pa kukhalabe ndi vacuum yoyenera mu injini ya vacuum, imakhalanso ndi udindo woyendetsa ma brake system poyendetsa. M'ma injini a petulo, chiwongolero champhamvu chimatha kugwira ntchito bwino chifukwa cha vacuum yomwe imapangidwa ndi njira yolowera. Mu dizilo, izi sizokwanira. Chifukwa chake, chifukwa cha pampu ya vacuum, ndizotheka kukanikiza chopondapo popanda kuyesetsa kwakukulu, komwe, mothandizidwa ndi vacuum, kumawonjezera kupanikizika nthawi zambiri. Ngati sichoncho, mutha kuwona zomwe ndizizindikiro za pampu yovumbula yolakwika.

Vacuum mpope - zizindikiro za ntchito yake

Chizindikiro chodziwika bwino cha kuwonongeka kwa vacuum ndikuchepetsa mphamvu yamabuleki. The turbocharger mphamvu chizindikiro akhoza kupita misala ngati anaika m'galimoto. Pamapeto pake, kuwonongeka kungadziwike ndi kutayikira kwa nyumba yopopera yokha. Inde, muyenera kudziwa komwe mungayang'ane ngati ikutha. Nthawi zambiri, komabe, ndizovuta zowongolera ma brake ndi clutch pedal zomwe zimamveketsa bwino kuti vacuum ikuyembekezera kusinthidwa kapena kusinthidwanso. Ndiye kusankha chiyani?

Chotsani ndikuwongolera kukakamiza kolakwika

Kuwonongeka kungatsimikizidwe momveka bwino pofufuza kuchuluka kwa vacuum yomwe idapangidwa. Kodi pampu ya vacuum imapanga vacuum yamtundu wanji? M'mitundu yokhazikika yamagalimoto, iyenera kugwira ntchito kuyambira -0,7 mpaka -0,9 bar. Njira yosavuta ndiyo kuyang'ana ndi kupima kuthamanga ndipo potsiriza onetsetsani kuti chipangizocho chikugwira ntchito. Chomwe chimayambitsa izi ndikuvala kapena kutayikira kwa pampu ya vacuum.

Kusintha kwapampu ya vacuum - ndikoyenera?

Zambiri zimadalira mtundu wa zowonongeka. Ngati mukutsimikiza kuti pampu ya vacuum ikutha, ingosindikizani. Kwa izi, zida zapadera zokonzera zimagwiritsidwa ntchito, zomwe zitha kugulidwa m'masitolo apaintaneti ndi m'masitolo ogulitsa. Nthawi zambiri mudzalipira ma zloty makumi angapo ndikutha kugwira ntchitoyo nokha. Zimakhala zovuta kwambiri pamene chotsukira chotsuka sichipereka vacuum yomwe mukufuna ndipo mukuwona zizindikiro zowoneka bwino za kuwonongeka. Idzafunika kubwezeretsedwanso kumalo obwezeretsanso.

Njira yomaliza (yokwera mtengo kwambiri) ndiyo kugula chinthu chatsopano. Komabe, mitengo yazigawo zotere nthawi zambiri imakhala yokwera katatu kuposa yomwe idasinthidwanso.

Vacuum - zomwe zimakhudza moyo wa mpope injini?

Popanga vacuum, pampu ya vacuum imatulutsa kutentha, chifukwa chake iyenera kukhazikika ndi mafuta a injini. Ichi ndi chifukwa chachikulu cha kulephera kwake. Zonyansa zomwe zimayandama m'mafuta komanso kusakwanira kwake kungapangitse mpope kugwidwa. Ichi ndichifukwa chake ndikofunikira kuyang'ana mafuta amtundu wabwino kwambiri ndikusamalira kusinthidwa pafupipafupi pafupipafupi komwe kumalimbikitsa injini. Mkhalidwe wa ma diaphragms a solenoid mu EGR umakhudzanso mkhalidwe wa vacuum, chifukwa umatsogoleranso vacuum ku chinthu ichi. Zowonongeka zimalowa mu pampu ya vacuum ndipo zimatha kuiwononga.

Pampu ya vacuum ndiyofunikira mu injini za dizilo. Mudzamva kuti yawonongeka mukatha kuyendetsa unit, kutsika bwino, kapena kutayikira kwamafuta ndi mafuta. Chisindikizo nthawi zambiri chimakhala yankho, koma ngati zinthu zapampu zakanidwa, pampuyo ingafunikire kusinthidwa. Ndipo mtengo uwu ndi woposa ma euro 100, choncho ndi bwino kusamalira unit. Mukamasintha mafuta, muzitsogoleredwa ndi khalidwe la mankhwala. Mwanjira imeneyi, mudzasamaliranso mkhalidwe wa pampu ya vacuum, yomwe imayikidwa ndi mafuta awa. Ndikoyeneranso kuyang'ana zotheka chigawo chifunga ndi kuwona ngati pali kutayikira kulikonse mu makina.
