Kodi ntchito ndi kapangidwe ka mphete za pistoni ndi chiyani?
Mphete za pistoni ndi mphete zachitsulo zomwe zimayikidwa pa ma pistoni. Ntchito zawo ndi mawonekedwe ake ndi awa:
Ntchito ya mphete za pisitoni:
Kutseka: Onetsetsani kuti mpweya uli bwino pakati pa chipinda choyaka injini ndi pistoni kuti mpweya usatuluke.
Kupaka mafuta: Pakayenda pisitoni, filimu yamafuta pakhoma la silinda imachotsedwa ndikubweretsedwa pamwamba pa pisitoni, ndikupanga mafuta.
Kutaya kutentha: Samutsani gawo la kutentha kwa mpweya ku khoma la silinda kenako muutaye mumlengalenga kuti muchepetse kutentha kwa injini.
Lamulirani mpweya wotulutsa utsi: Pakayenda pisitoni, mpweya wotulutsa utsi umadulidwa kuti utuluke mosavuta.
Kapangidwe ka mphete za pistoni:
Mphete zophatikizana za pistoni: Zopangidwa ndi chinthu chimodzi, zimakhala ndi kapangidwe kosavuta koma zolimba pang'ono ndipo zimatha kusinthika mosavuta.
Mphete za pistoni zolumikizidwa: Zopangidwa ndi zinthu ziwiri kapena zingapo zolumikizidwa pamodzi, zimakhala ndi mphamvu zambiri ndipo ndizoyenera kugwiritsa ntchito injini zothamanga kwambiri komanso zonyamula katundu wambiri.
Mphete zophatikizana za pistoni: Zopangidwa ndi mbale zozungulira zamitundu yosiyanasiyana ndi zipangizo, zimatha kusinthidwa ngati pakufunika kutero kuti ziwongolere magwiridwe antchito.
Mapangidwe ndi magwiridwe antchito amenewa amathandiza kuti mphete za pistoni zigwire ntchito yofunika kwambiri mu injini, zomwe zimathandiza kuti injiniyo igwire bwino ntchito komanso igwire bwino ntchito.
Mphete za pistoni zimapangidwa makamaka ndi chitsulo chosungunuka, ndipo palinso mitundu yowonjezera monga chitsulo chosungunuka, chitsulo ndi zipangizo zapadera zophatikizika.
Mitundu yayikulu ya zinthu za pistoni ndi
Zinthu zachitsulo zotayidwa
Youdaoplaceholder0 Chitsulo chopangidwa ndi imvi chokhazikika : Ku China, mitundu ya chitsulo chopangidwa ndi imvi monga HT250 ndi HT300 imagwiritsidwa ntchito kwambiri. Kapangidwe kake ka metallographic kayenera kukwaniritsa zofunikira za matrix yabwino ya lamellar pearlite ndi kugawa kwa graphite kofanana kuti zitsimikizire kuti sizingawonongeke.
Chitsulo chopangidwa ndi Youdaoplaceholder0: Mwa kuwonjezera zinthu monga Cr, Mo, ndi Cu kuti ziwonjezere magwiridwe antchito, chitsulo chopangidwa ndi cr-mo ndi cr-mo-cu chimapangidwa, zomwe zimalimbitsa kukana kukalamba komanso kukana kutentha kwambiri.
Zipangizo zapadera zogwiritsira ntchito
Youdaoplaceholder0 Zipangizo zachitsulo : Mphete za pisitoni zachitsulo zimagwiritsidwa ntchito mu injini zamphamvu kwambiri, ndipo mawonekedwe awo pamwamba amakulitsidwa kudzera mu njira monga kupopera kutentha ndi electroplating.
Zipangizo zophatikizika za Youdaoplaceholder0 : monga mphete za piston zopangidwa ndi MC nylon 6 ndi molybdenum disulfide filler, zomwe ndizoyenera pazinthu zinazake monga ma compressor ndipo zili ndi ubwino wochepa wa kukangana komanso kupepuka.
Youdaoplaceholder0 kukonza ndi kulimbitsa zinthu
Youdaoplaceholder0 Kuchiza pamwamba: kuphatikizapo njira monga chromium plating, nitriding, phosphating, ndi physical deposition, zitha kukulitsa kwambiri kukana kuwonongeka ndi kukana dzimbiri.
Youdaoplaceholder0 Kuwongolera kwa Microscopic : Mwa kukonza mawonekedwe a graphite (monga kugawa kowongoka bwino kapena vortex) ndikusintha kapangidwe ka phosphorous, mawonekedwe a makina a zinthuzo amawongoleredwa.
Zolakwika za mphete ya pistoni zimaonekera makamaka ngati kugwiritsa ntchito mafuta molakwika, kuchepa kwa mphamvu, komanso phokoso loipa kwambiri, zomwe zimachitika makamaka chifukwa cha zinthu monga kutsekeka kwa kaboni, zolakwika pazinthu, kapena kuyika kosayenera. Youdaoplaceholder0 Mayankho wamba amaphatikizapo mapulani ochizira omwe cholinga chake ndi kukonza zinthu zosasokoneza, kusintha zigawo ndi kusintha momwe ntchito ikuyendera.
Youdaoplaceholder0 Chochitika chachikulu cha cholakwika
Youdaoplaceholder0 Kugwiritsa ntchito mafuta molakwika : Kuwonongeka kapena kutsekeka kwa mphete za pistoni kumapangitsa kuti mafuta alowe m'chipinda choyaka moto, ndipo utsi wabuluu umatuluka mu chitoliro chotulutsa utsi, zomwe zimafuna kuti mafuta awonjezeredwe nthawi zambiri.
Youdaoplaceholder0 Kuchepa kwa mphamvu: Kulephera kwa chisindikizo kumabweretsa kupanikizika kosakwanira kwa silinda, komwe kumawonetsedwa ngati kufooka kwa liwiro komanso kuchuluka kwa kugwiritsa ntchito mafuta.
Youdaoplaceholder0 Phokoso losazolowereka ndi kutentha kwambiri : Pamene mphete yasweka kapena mafuta akulephera kukanda, injini imapanga phokoso logundana, limodzi ndi kukwera kosazolowereka kwa kutentha kwa madzi.
Njira yodziwika bwino yogwiritsira ntchito ma compressor a mphete ya piston ingagawidwe m'magawo asanu ofunikira: kukonzekera mafuta, kuteteza zigawo, kukhazikitsa ma compressor, kuika ma piston pamalo ake ndi kulekanitsa zida. Chisamaliro chapadera chiyenera kuperekedwa pa chithandizo cha mafuta, kulinganiza zigawo, ndi zoletsa kugwiritsa ntchito.
Youdaoplaceholder0 Njira zazikulu zogwirira ntchito
Chithandizo cha mafuta a Youdaoplaceholder0 .
Ikani mafuta a injini mofanana ku ma grooves a piston ring ndi makoma amkati mwa masilinda kuti muchepetse kukwerana.
Pukutani ndi nsalu yopanda ulusi kuti mupewe zotsalira za zinthu zakunja zomwe zingakhudze magwiridwe antchito otsekera.
Chitetezo cha Youdaoplaceholder0 cha zigawo .
Mukachotsa chivundikiro cha ndodo yolumikizira, ikani payipi ya rabara pamwamba pa ulusi wa boluti ya ndodo yolumikizira kuti khoma la silinda lisakandane panthawi yoyika.
Chongani chizindikiro cha njira pamwamba pa pistoni (monga muvi) kuti muwonetsetse kuti ikugwirizana ndi mtundu wa injini.
Kukhazikitsa kwa compressor ya Youdaoplaceholder0 .
Sankhani chitsanzo cha compressor chomwe chikugwirizana ndi kukula kwa pistoni ndikuwonetsetsa kuti kulimba ndi mphamvu ya pepala lachitsulo zikukwaniritsa miyezo.
Kanikizani chikhadabo chotulutsa motsatira malangizo a m'buku, ndikuzungulira chipangizo cha ratchet mozungulira wotchi kuti mutsegule mphete yokakamiza ndikuzungulira pisitoni.
Mangani compressor mozungulira wotchi kuti mulowetse mokwanira mphete za pistoni mu mizere ya mphete.
Youdaoplaceholder0 malo oimika pisitoni .
Ikani gawo la pansi la pistoni mu silinda pa ngodya ndipo pang'onopang'ono gwirani pamwamba ndi chogwirira cha nyundo chamatabwa mpaka mphete yokakamiza itakhudza ndege ya silinda.
Yang'anirani mtunda pakati pa ndodo yolumikizira ndi malo osungiramo zinthu kuti mupewe ngozi zogundana.
Kulekanitsa zida za Youdaoplaceholder0 .
Mukatsimikizira kuti mphete yoyamba ya pistoni yalowa mu silinda, siyani kumenya. Ndikoletsedwa mwamphamvu kuikakamiza patsogolo ndi zida zachitsulo.
Tembenuzani chikhadabo chotulutsa ratchet motsatira wotchi, pang'onopang'ono muchepetse kupanikizika kwa compressor, kenako chotsani chidacho.
Youdaoplaceholder0 Mfundo zazikulu zoti muzindikire
Youdaoplaceholder0 Kufotokozera za mafuta: Musagwiritse ntchito mafuta a injini omwe ali ndi kukhuthala kosakwaniritsa muyezo wa SAE 30, apo ayi angayambitse kuyika kwa kaboni mu ring groove.
Kutsimikizira malo a Youdaoplaceholder0 : Pambuyo poti pistoni ikakankhira mkati, ndikofunikira kuyang'ana momwe zilembo/manambala a zilembo pa ndodo yolumikizira ndi buku la ndodo yolumikizira zilili.
Youdaoplaceholder0 Zotsutsana ndi zida : Ngati compressor yaima panthawi yopatukana, pisitoni iyenera kubwezedwa kuti isinthe malo a mphete yokakamira. Kugwiritsa ntchito mwankhanza ndikoletsedwa kotheratu.
Youdaoplaceholder0 Malangizo osankha zida
Ma compressor achitsulo chopangidwa ndi cast iron ndi oyenera ma pistoni okhala ndi mainchesi osapitirira 100mm, pomwe achitsulo chopangidwa ndi cast iron ndi oyenera ma injini akuluakulu othamangitsidwa.
Ma compressor okhala ndi zida zotsekera ma ratchet a mbali ziwiri amatha kulimbitsa kukhazikika kwa ntchito ndikuchepetsa chiopsezo chomasuka panthawi yogwira ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
