Kodi kuonanso kusiyana matenthedwe wa pisitoni mphete: katswiri malangizo

Pa injini kukonza lalikulu zambiri ndi mafunso okhudza kusankha bwino matenthedwe kusiyana. Pisitoni mphete ndi lalikulu kwambiri kusiyana mu loko ndi axially ntchito molondola. Koma oipitsitsa, ngati kusiyana ndi chochepa watengedwa. Pankhaniyi, injini sizigwira ntchito kwa nthawi yaitali ndipo pambuyo makilomita masauzande ochepa kachiwiri anapempha pa wapogawanikira lapansi. Tiyeni tikambirane mmene kusankha bwino matenthedwe kusiyana pisitoni mphete ndi mmene Ndipotu, ayenera Choncho kukhala.

Mwachidule ndi mfundo

The pisitoni tichipeza mphete atatu, omwe amachita ntchito yeniyeni. Chapamwamba awiri ntchito kukhala psinjika mu injini. Ngati zidzachitika kapena kufika mlingo kukayikira zoti likuwonongeka, kusiya makhalidwe zazikulu olimbana mkati kuyaka, mafuta ukuwonjezeka ndi mavuto ena. M'munsi mphete amatchedwa "tsinde". Kuyambira mutu ndi bwino udindo wake pa ntchito ya unit mphamvu.

Ntchito ya injini kuyaka mkati zitsulo mbali kuwonjezera. Chifukwa imeneyi, kusiyana matenthedwe wa pisitoni mphete yafupika. Ngati unali anatola molakwika, kuti ndi zosakwana kololeka, ndiye kuti afikire ku opaleshoni kutentha olimbana pisitoni adzakhala zikande khoma yamphamvu.

ndi kusiyana matenthedwe wa pisitoni mphete Sandama chiyani?

Akuyendera mwachindunji manambalawo, tisaiwale kuti muyeso wa kusiyana ayenera anachita mbali unheated. Pamene mphete imeneyi chofunika adzaikidwa mu yamphamvu ya. probes wapadera kapena mbale ntchito kudziwa chizindikiro. Nthawi zambiri phindu kololeka wa lisaoneke zimasiyanasiyana 0,25 kuti 0,5 mm. Koma malingana ndi mtundu wa galimoto ndi kusinthidwa ake, deta izi zosiyanasiyana Komabe Ndi bwino kufunsa chisanadze Ice zolembedwa.

ndi kusiyana matenthedwe wa pisitoni mphete ayenera Vaz magalimoto chiyani? Pakuti mphete psinjika ayenera kukhala mu uthunthu 0.25-0.4 mm, ndi mafuta kulamulira mphete - 0.25-0.5 mm. Kachiwiri, Chiwerengerochi angakhale osiyana pang'ono, kotero muyenera kuganizira injini chitsanzo yeniyeni.

ntchito luso kayesedwe

Chinthu choyamba kuchita ndicho kubweretsa mphete ku mbali ya yamphamvu ya. Kenako anaika mu gawo lakunja la kagawo yoikidwayo. Kenako muyenera ya n'kupanga imene kusiyana ndi anatsimikiza. Ngati mphete aikidwa mwachindunji mkati yamphamvu, ndi miyeso ayenera ikuchitika payokha, kuyambira mtunda pakati pa malekezero a zingasiyane.

Chinthu choyamba kuchita ndicho kuika pisitoni mphete mafuta engine. Monga yomaliza tanthauzo lapadera apa si monga mwa ntchito ya udzayaka zonse. mphete Komanso amasuntha khoma yamphamvu. Ndipo zimenezi ziyenera kuchitidwa kokha yamphamvu, kumene mphete chingagwiritsidwe ntchito m'tsogolo. Makamaka yabwino kugwira mawerengedwe ili, ngati pisitoni kale kuchotsedwa. Pankhani ya kusuntha posachedwapa mokwanira ndigwire inabala mphete mwa 3-5 mm, pafupifupi pa malo pamene adzakhala mu injini kuyaka mkati pa ntchito. Tidamva ntchito ya probes (mipiringidzo) ndi kupeza mfundo chofunika. Gwiritsani ntchito "Buku" pamene kukatenga chilolezo cha pisitoni mphete. Dizilo "Ford kuperekezedwa '1.6 Mwachitsanzo, ayenera kukhala kusiyana kwa 0.3-0.5 mamilimita kwa chapamwamba psinjika mphete ndi 0.2-0.45 mamilimita kwa tsinde.

Zovuta kukonza CPG

Otchedwa "kapitalka" Engine Zovuta zikutanthauza zonse yamphamvu-pisitoni gulu, chifukwa ndi phunziro kwa katundu wapamwamba matenthedwe pa ntchito. Choncho, pistons, psinjika ndi tsinde mphete ali anaikanso chinawonjezeka avale. Nthawi zina, kumene mphete sanabadwe anafika yovuta kuvala adazilola. Pa zambiri zamakono Ice kusiyana 1 mamilimita kale ankaona zowawitsa ndipo mu nkhani iyi ndi zofunika m'malo mphete. Choncho, pamene injini kukonzanso bwino kusintha mphete onse pa pistons, ngakhale iwo akadali woyenera. Tiyenera izi makilomita 50 000 kachiwiri disassemble galimoto ndi.

Tiyeneranso kumvetsetsa kuti si nthawi zonse chilolezo kwa mphete yoyamba ndi yachiwiri psinjika ali yemweyo. A chitsanzo chapadera ndi zoweta katundu makina. Mwachitsanzo, kusiyana matenthedwe wa pisitoni mphete "Kamaz" Chioneke motero:

• choyamba psinjika mphete - 0.20-0.40 mm (yatsopano);
• chachiwiri - 0.30-0.50 (yatsopano);
• Tsinde 0.25-0.50 (yatsopano).

Mu nkhani iyi, avale kololeka kwa mitundu yonse ya mphete sayenera upambana 1 mm. Ngakhale 0,9 mamilimita akhoza kale kuonedwa yovuta. Ngakhale kuti nthawi zambiri popanda disassembly CPG anamvetsa kuti mphete kufunsidwa m'malo.

Kuchuluka mafuta

Kwambiri galimoto opanga ano kuonjezera chilolezo cha pisitoni mphete injini zake. Ngati mitundu ina ya injini kuyaka mkati ndi ovuta 1 mm, koma injini yatsopano ku "BVM" kapena "Audi" 12 mm - kusiyana latsopano injini mphete opanda pake. Apa muyenera kumvetsa mfundo ina yofunika kwambiri.

chakuti kuyaka kwa kusakaniza mafuta mpweya anapanga mpweya umene kulowa poyambira wa pisitoni lapansi. Choncho iwo anayamba kulenga kuthamanga mkati mwa mphete, ndi kulola kuti achepetsa khoma yamphamvu.

N'chifukwa chake pamene mkati kuyaka injini pa zachabezo ndi otsika liwiro downforce si wamkulu monga pa katundu mkulu. Chifukwa chake n'chakuti kuchuluka kwa mafuta mu chipinda kuyaka n'chosiyana kwambiri. The chachiwiri psinjika mphete gawo amanyamula vuto kuchipala, kuchotsa filimu kuchokera yamphamvu ya. Ngati olema, ukuwonjezeka lubricant mowa pa nthawi, makamaka pa zachabezo ndi otsika liwiro engine.

Matenthedwe kusiyana pisitoni mphete Vaz-21083

M'banja galimoto 2108, amadziwika ngati "eyiti" kapena "chisel", akhoza kudzitama injini odalirika kwambiri. Ngakhale mosamala chifukwa ndi kuthamanga kwambiri. Komabe, ngati kukonza lalikulu muyenera kulipira mwapadera kuti kusiyana matenthedwe. Anthu ambiri ngofunika aliyense kuti izi ndi kusiya mphete akale. Koma kukonzanso izi Sindizakubweretsanso zotsatira kuyembekezera, makamaka ngati injini wapogawanikira anachita chifukwa mowa kuchuluka mafuta.

Pali zinthu zingapo wapadera. Makamaka, chilolezo pazipita mu mphete onse - 0,15 yekha mm. Choncho kwa mwadzina 1 psinjika a 0,04-0,075 mm, kwachiwiri - 0,03-0,065 mamilimita ndi tsinde - 0,02-0,055 mm. Ndi kofunika kwambiri kuti tikwaniritse mkulu mwatsatanetsatane. Njira - kunenera grooves ndi pisitoni mphete. Mukhoza kugwiritsa ntchito micrometer, komanso probes. Miyezo pa pisitoni ayenera kuchitika m'malo osiyanasiyana padziko circumference a.

mokoma zingapo zofunika

Mmene kukonza adzakhala anatola ndi kusiyana matenthedwe wa pisitoni mphete olimbana dizilo kapena mafuta zimatengera moyo wa gulu yamphamvu-pisitoni ndi zoona, mphete. Scuffing chifukwa mphete mikangano ya yamphamvu ndi kumabweretsa imfa osati psinjika komanso masamu. Sangalalani zazing'ono kuyambira kubwezeretsa chikhalidwe ntchito adzafunika resurfacing, ndi Zikavuta kwambiri - anaberekera yamphamvu.

Ngati zozungulira mphete avale, ndiye kwambiri sakuyenda mu kusindikiza chipinda kuyaka. Zimenezi zimabweretsa kuwonongeka kwa mphamvu injini ndi kuchuluka kumwa mafuta galimoto.

Chavuta ndi kusiyana pang'ono

Zingatanthauze kuti tikwaniritse psinjika wabwino amafunika kusiyana aang'ono ngati nkotheka. Pankhaniyi mafuta sadzawotchedwa. Zonsezi yekha mwina woona. mfundo ndi yakuti ngati kusiyana kuwonjezeka adzakhala zosakwana kololeka, padzakhala kuswa lamulo kuwombola kutentha. Izi mwina chifukwa kuchuluka mphete mikangano panalembedwa lapansi. Chifukwa, pali burrs, ndipo inapita patsogolo avale wa mphete yamphamvu. Mu chimaliziro, psinjika mphete sikulenga kuthamanga bwino ndipo tsinde kusiya mafuta zonenepa ndi. Patapita nthawi, injini mphamvu atayika, kumaonjezera otaya lubricant ndi chatsitsa kuyaka kukhazikika mkati.

kuti adzimvera

Monga mukuonera, n'kofunika kwambiri kudziwa zimene zikufunika kusiyana pisitoni mphete kwa mtundu winawake wa engine. Aliyense wopanga n'chakuti mwadzina ndi cholandirika phindu. Iwo akulimbikitsidwa kutsatira. Ngati kukonzanso kwa mphete ndi chobvalidwa, kuti 50%, ndiye ndi bwino m'malo ina.

Osati moyipa bwino kuposa utachepa chilolezo. Chifukwa cha yotsirizira kumawonjezera kutentha mu chipinda kuyaka, yamphamvu ndi ntchito kuwonongeka makina. Zonsezi zimachititsa zina ndalama kwambiri. Kuti sizinachitike, m'pofunika bwino kusankha chilolezo cha pisitoni mphete ndipo anatsogolera yekha ndi gwero wokhulupirika. The malangizo ntchito ndi kusamalira wina ndi galimoto zalembedwa deta muyenera ndipo iyenera kugwiritsidwa ntchito mu ntchito.
