Mokhoa oa ho Thibela Cylinder Gasket Wear ea Diesel Engine

Nakong ea ts'ebeliso ea sete ea jenereithara ea diesel, gasket ea silinda ea enjene ea diesel e bonolo ho tlosoa, e bakang ho lutla ha moea le metsi a enjene ea diesel, e amang ts'ebetso ea diesel genset ka botebo.Ka hona, re lokela ho etsa mosebetsi o motle mosebetsing oa thibelo ho thibela tšenyo.Sehlooho sena se tšohla mokhoa oa ho thibela tšenyo ea silinda gasket ha u sebelisa sete ea jenereithara ea diesel .

A. Mehato e thibelang

1. Harola ka nepo le ho kopanya cylinder block le cylinder head ea enjene ea disele.

2. Kopano e nepahetseng ea li-cylinder liner.Pele cylinder liner e bokelloa ka har'a silindara, litšila le mafome holim'a metsi, likarolo tse ka holimo le tse ka tlaase tsa lesoba la setulo sa cylinder block ho ea lehetleng li lokela ho tlosoa ka botlalo.Phapang pakeng tsa sefofane se ka holimo sa li-cylinder liner le sefofane se ka holimo sa li-cylinder block, le phapang ea bophahamo pakeng tsa li-cylinder liners tlas'a hlooho e tšoanang ea silinda e tlameha ho finyella litlhoko tse boletsoeng.Nakong ea ho kenya mochine oa khatiso oa li-cylinder liner, lisebelisoa tse khethehileng li tla sebelisoa ho hatella lesela la cylinder ka matla a lekanang.Ho thibetsoe ka thata ho otla bokaholimo ba cylinder liner ho qoba deformation ea lehae ea boema-kepe ba cylinder.

3. Matlafatsa tlhahlobo ea sebaka se tiisitsoeng sa hlooho ea cylinder le cylinder block ho bona hore na e holofetse kapa che.Sebelisa rula le seea-le-moea ho hlahloba sebaka se tiisitsoeng ho latela litsela tsa longitudinal le tse tšekaletseng.Ka kakaretso, ho se lekane ha sebaka sa ho tiisa pakeng tsa cylinder block le hlooho ea cylinder ha ea lokela ho feta 0.10 mm.Ho se leka-lekane ha ho fete 0.03 mm ka bolelele leha e le bofe ba 100 mm.Ha hoa lokela ho ba le likarolo tsa convex kapa concave holim'a ho tiisa.

4. Tlosa liboutu tsa hlooho ea silinda ka nepo.Tiisa liboutu tsa hlooho ea cylinder ho latela tatellano e boletsoeng, linako le torque.

5. Khetho e nepahetseng ea cylinder gasket.The cylinder head gasket e khethiloeng e tlameha ho finyella litlhoko tsa lisebelisoa tsa pele tse nang le boleng bo ka tšeptjoang.Tataiso ea ho kenya e lokela ho lefshoa ha u kenya.Molao-motheo oa motheo ke hore moeli oa curling o lokela ho tobana le sebaka sa ho kopana kapa sefofane se thata seo ho leng bonolo ho se lokisa.Lintlha ke tse latelang: haeba cylinder head gasket ka boeona e na le letšoao la ho kenya, e kenye ho latela letšoao la ho kenya;haeba ho se na letšoao, hlooho ea cylinder e entsoe ka tšepe e entsoeng ka tšepe, 'me mokokotlo o tla tobana le hlooho ea silinda.Ha hlooho ea silinda e entsoe ka aluminium e entsoeng, crimping e lokela ho tobana le block cylinder.Ha hlooho ea cylinder le cylinder block kaofela li entsoe ka aluminiamo e entsoeng, crimping e lokela ho shebana le moeli oa convex oa liner ea silinda e metsi.

6. Tiisa liboutu tsa hlooho ea silinda ka nepo.Ho tiisoa ha li-cylinder head bolts ke karolo ea bohlokoa ka ho fetisisa ho netefatsa boleng ba tiiso ea cylinder head gasket.Ho sa tsotellehe hore na ts'ebetso ena e tsitsitse kapa e sa ama ka ho toba boleng ba tiiso ea cylinder head gasket, kahoo e tlameha ho sebetsoa ka mokhoa o tiileng le litekanyetso tsa tekheniki.

B. Tšebeliso e nepahetseng le tlhokomelo

1. Nakong ea ho matha ka nako (30-50h) le ka linako tse ka bang 200h, liboutu tsa cylinder tse ncha kapa tse nchafalitsoeng. ho hlahisa lihlopha Lienjine tsa diesel li hloka ho hlahlojoa le ho tiisoa hang ho latela torque e boletsoeng.Ka nako e ts'oanang, re tlameha ho ela hloko lintlha tse ling: sludge, carbon deposit, coolant, oli ea enjene le litšila tse ling le mokelikeli o ka mokoting oa bolt o tla hloekisoa ka ho feletseng.Haeba ho hlokahala, khoele ea screw e tla hloekisoa ka pompo, 'me moea o hatelitsoeng o tla sebelisoa ho butsoela hantle; hloekisa liboutu tsa cylinder hantle 'me u li hlahlobe ka hloko.Haeba ho na le mapetsong, likoti le melala, li lokela ho hlajoa 'me li ke ke tsa hlola li sebelisoa; pele ho kenngoa liboutu tsa li-cylinder, ho lokela ho tšeloa oli e nyenyane karolong ea khoele le holim'a setšehetso sa flange ho fokotsa khohlano e omileng ea khoele. .

2. Sheba le ho lokisa nako ea ente ka nako.Khatello ea ente ea ente e tlameha ho finyella litlhoko tse boletsoeng, 'me phoso ea khatello ea ente ea silinda e' ngoe le e 'ngoe ha e fete 2%.Leka ho qoba malakabe khafetsa tlas'a mojaro o boima, mocheso o phahameng le lebelo le phahameng, 'me u thibele ho potlakisa ka potlako tlas'a mojaro.

3. Pele o nkela sebaka se secha sa silinda gasket, qala ka ho hlahloba hore na bokaholimo ba moqomo oa gasket ke concave, convex, senyehile, joalo-joalo, hore na boleng bo ka tšeptjoa, le hore na ho bata ha hlooho ea silinda le cylinder block ho fihlela litlhoko, joale hloekisa gasket ea cylinder, hlooho ea cylinder le cylinder block, 'me u li omise ka moea o hatelitsoeng, e le ho qoba tšusumetso ea litšila holim'a tiiso.

4. The cylinder head gasket e khethiloeng e lokela ho ba lisebelisoa tsa pele tse finyellang litlhoko (litlhaloso, mohlala) le ho ba le boleng bo ka tšeptjoang.Ela hloko matšoao a holimo le a tlase ha u kenya, e le ho thibela ho kenngoa ho tloha morao le ho baka ho hlōleha ha motho.
