Munayamba Kudzifunsa Kuti Zisindikizo Zing'onozing'ono Za Mafuta Zimasunga Bwanji Makina Aakulu Akuluakulu Osatayikira?

Chiyambi: Kagawo kakang'ono, Udindo Waukulu
Injini yagalimoto yanu ikadontha mafuta kapena pampu yamagetsi yamagetsi ikutha, wosewera wofunikira koma wosazindikirika nthawi zambiri amakhala kumbuyo kwake - chisindikizo chamafuta. Chigawo chooneka ngati mphetechi, chomwe nthawi zambiri chimakhala masentimita angapo m'mimba mwake, chimakhala ndi cholinga cha "zero leakage" mu ufumu wamakina. Masiku ano, timayang'ana mwatsatanetsatane kapangidwe kake komanso mitundu yodziwika bwino yamafuta osindikizira.

Gawo 1: Mapangidwe Olondola - Chitetezo cha Zigawo Zinayi, Umboni Wotulutsa
Ngakhale chaching'ono, chosindikizira chamafuta chimakhala ndi mawonekedwe olondola modabwitsa. Chisindikizo chamafuta am'mafupa (mtundu wodziwika kwambiri) chimadalira ntchito yolumikizidwa yazigawo zazikuluzikuluzi:

1. The Steel Backbone: Metal Skeleton (Mlandu/Nyumba)

   • Zofunika & Fomu:Nthawi zambiri amapangidwa kuchokera kuzitsulo zapamwamba kwambiri, zomwe zimapanga "mafupa" a seal.

   • Ntchito Yaikulu:Amapereka structural rigidity ndi mphamvu. Imawonetsetsa kuti chisindikizocho chimasunga mawonekedwe ake pansi pa kupsinjika kapena kusintha kwa kutentha ndipo chimakhazikika bwino m'nyumba ya zida.

   • Chithandizo cha Pamwamba:Nthawi zambiri amakutidwa (mwachitsanzo, zinki) kapena phosphated kuti apititse patsogolo dzimbiri ndikuonetsetsa kuti pamakhala cholimba mkati mwabowo.

2. Mphamvu Yoyendetsa: Garter Spring

   • Malo & Fomu:Nthawi zambiri kasupe wopindika bwino wa garter, wokhala bwino paphoko pamizu ya milomo yotseka.

   • Ntchito Yaikulu:Amapereka mosalekeza, yunifolomu ma radial mavuto. Ili ndiye fungulo la ntchito ya chisindikizo! Mphamvu ya masika imalipira kuvala kwa milomo yachilengedwe, kutsekeka pang'ono kwa shaft, kapena kutha, kuwonetsetsa kuti milomo yoyambira imalumikizana pafupipafupi ndi shaft yozungulira, ndikupanga bandi yokhazikika yosindikiza. Lingalirani ngati "lamba wokhazikika" wokhazikika.

3. The Leak-Proof Core: Pulayimale Yosindikiza Milomo (Milomo Yaikulu)

   • Zofunika & Fomu:Opangidwa kuchokera ku ma elastomers ochita bwino kwambiri (monga, Nitrile Rubber NBR, Fluoroelastomer FKM, Acrylate Rubber ACM), opangidwa kukhala mlomo wosinthika wokhala ndi m'mphepete lakuthwa lomata.

   • Ntchito Yaikulu:Ichi ndi "chotchinga chachikulu," kukhudzana mwachindunji ndi shaft yozungulira. Ntchito yake yayikulu ndikusindikiza mafuta opaka / mafuta, kuteteza kutuluka kwakunja.

   • Chida Chachinsinsi:Kapangidwe kake kapadera kamagwiritsa ntchito mfundo za hydrodynamic panthawi yozungulira shaft kupanga filimu yamafuta owonda kwambiri pakati pa milomo ndi shaft.Filimuyi ndiyofunika:imatulutsa malo olumikizana, imachepetsa kutentha kwapang'onopang'ono ndi kuvala, pomwe imagwira ngati "damu yaying'ono," pogwiritsa ntchito kuthamanga kwapamtunda kuti mafuta asatayike. Mlomo nthawi zambiri umakhala ndi tinthu tating'onoting'ono tobwezera mafuta (kapena kapangidwe ka "kupopera") komwe "kupopa" madzi aliwonse omwe akuthawa kubwerera kumbali yosindikizidwa.

4. The Dust Shield: Milomo Yotseka Yachiwiri (Fumbi Lip/Milomo Yothandizira)

   • Zofunika & Fomu:Amapangidwanso ndi elastomer, yomwe ili pamtundaakunjambali (mbali yamlengalenga) ya mlomo woyamba.

   • Ntchito Yaikulu:Imagwira ntchito ngati "chishango," kutsekereza zowononga zakunja monga fumbi, dothi, ndi chinyezi kulowa m'bowo lotsekedwa. Kulowetsedwa kwa zonyansa kumatha kuipitsa mafuta, kufulumizitsa kuwonongeka kwa mafuta, ndikuchita ngati "sandpaper," kuthamangitsa kuvala pamilomo yoyamba ndi shaft pamwamba, zomwe zimapangitsa kulephera kusindikiza. Mlomo wachiwiri umakulitsa kwambiri moyo wa chisindikizo chonse.

   • Contact & Mafuta:Mlomo wachiwiri umakhalanso ndi kusokoneza komwe kumayenderana ndi shaft, koma kukhudzana kwake kumakhala kochepa kwambiri kusiyana ndi mlomo woyambirira. Nthawi zambiri sizimafuna mafuta opaka filimu ndipo nthawi zambiri amapangidwa kuti aziuma.

Gawo 2: Kufotokozera Nambala Zachitsanzo: SB/TB/VB/SC/TC/VC Yofotokozedwa
Nambala zachisindikizo zamafuta nthawi zambiri zimatsata miyezo monga JIS (Japanese Industrial Standard), pogwiritsa ntchito kuphatikiza zilembo kutanthauza mawonekedwe. Kumvetsetsa ma code awa ndikofunikira pakusankha chisindikizo choyenera:

• Kalata Yoyamba: Imawonetsa Kuwerengera kwa Milomo & Mtundu Woyambira

  • S (Mlomo Umodzi): Mtundu wa Milomo Umodzi

    • Kapangidwe:Mlomo wosindikiza wokhawokha (mbali yamafuta).

    • Makhalidwe:Kapangidwe kophweka, kukangana kochepa kwambiri.

    • Ntchito:Oyenera m'nyumba zaukhondo, zopanda fumbi momwe chitetezo cha fumbi sichifunikira, mwachitsanzo, mkati mwa ma gearbox otsekedwa bwino.

    • Zitsanzo Zodziwika:SB, SC

  • T (Double Lip with Spring): Mitundu Ya Milomo Yawiri (yokhala ndi Spring)

    • Kapangidwe kake: Muli ndi milomo yotseka yoyambirira (ndi kasupe) + milomo yotseka yachiwiri (milomo yafumbi).

    • Makhalidwe: Amapereka ntchito ziwiri: madzimadzi osindikizira + osaphatikiza fumbi. Chisindikizo chogwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito pagulu.

    • Mitundu Yodziwika: TB, TC

  • V (Double Lip, Spring Exposed / Dust Lip Prominent): Milomo Yawiri yokhala ndi Milomo Yodziwika Kwambiri (yokhala ndi Spring)

    • Kapangidwe:Lili ndi milomo yosindikiza yoyambirira (yokhala ndi kasupe) + milomo yotseka yachiwiri (milomo yafumbi), pomwe milomo yafumbi imatuluka kwambiri kupyola m'mphepete mwakunja kwa chitsulo.

    • Makhalidwe:Mlomo wafumbi ndi wokulirapo komanso wowoneka bwino, womwe umapereka mwayi wapamwamba wopatula fumbi. Kusinthasintha kwake kumapangitsa kuti ichotse bwino zowononga pamtunda.

    • Ntchito:Zopangidwira makamaka m'malo ovuta, auve okhala ndi fumbi lambiri, matope, kapena kukhudzidwa ndi madzi, mwachitsanzo, makina omanga (zofukula, zonyamula katundu), makina aulimi, zida zamigodi, malo opangira magudumu.

    • Zitsanzo Zodziwika:VB, VC

• Kalata Yachiwiri: Imasonyeza Malo a Spring (Ogwirizana ndi Mlandu Wachitsulo)

  • B (Spring Inside / Bore Side): Mtundu Wamkati Wamkati

    • Kapangidwe:Masimpe aakubikkwamkatimlomo woyamba wosindikiza, kutanthauza kuti uli kumbali yomata (mafuta). Mphepete mwa kunja kwazitsulo zachitsulo nthawi zambiri zimakhala zophimbidwa ndi mphira (kupatulapo zojambula zowonekera).

    • Makhalidwe:Izi ndizomwe zimachitika kwambiri masika. Kasupe amatetezedwa ndi mphira ku dzimbiri zakunja zapa media kapena kupanikizana. Pakuyika, mlomo umayang'ana mbali yamafuta.

    • Zitsanzo Zodziwika:SB, TB, VB

  • C (Spring Outside / Case Side): Mtundu Wakunja Kwakasupe

    • Kapangidwe:Spring ili paakunjambali (mbali yamlengalenga) ya milomo yosindikizira yoyamba. Labala yoyambirira ya milomo nthawi zambiri imatsekereza mafupa achitsulo (opangidwa mokwanira).

    • Makhalidwe:Masimpe alajanika mujulu. Ubwino waukulu ndikuwunika kosavuta komanso kusinthika kwa kasupe (ngakhale kumafunikira kawirikawiri). Itha kukhala yabwino kwambiri m'nyumba zina zokhala ndi malo ochepera kapena zofunikira zapangidwe.

    • Chidziwitso chofunikira:Kuyika kolowera ndikofunikira - milomopaamayang'ana mbali ya mafuta, ndi kasupe kumbali ya mpweya.

    • Zitsanzo Zodziwika:SC, TC, VC
