ho hloleha ha turbine. Joang ho rarolla bothata?

mochine oa turbocharger, ho sa tsotellehe ho tšoarella (lilemo tse 10) le ho apara ho hanyetsa ho tšepisitsoeng ke moetsi, ho ntse ho hlōleha, ho senya le ho senya. Ka hona, nako le nako hoa hlokahala ho felisa ho robeha ha turbine ea lienjineri tse tukang tsa ka hare tsa dizeli le peterole. 'Me e le hore u bone matšoao a ho senyeha ka nako, u lokela ho ela hloko kamehla boitšoaro bo sa tloaelehang ba koloi.

The turbine ha e sebetse:

• ho na le maikutlo a hore tshusumetso e lahlehileng (matla a fokotsehileng);
• ha o potlakisa koloi ho tloha phala e ntshang metsi tsuba bolou, botsho, bosweu;
• ka enjene e sebetsang ho letsa molodi ho utloahala, lerata, ho sila;
• ka tšohanyetso tshebediso e eketsehileng kapa ke ho tsoa ha oli;
• hangata khatello e theoha moea le oli.

Haeba matšoao a joalo a hlaha, joale maemong ana ho hlokahala tlhahlobo e felletseng ea turbine enjene ea dizeli.

Matšoao le ho senyeha ha turbocharger

1. mosi o moputsoa - letšoao la ho chesa oli ka har'a li-cylinders tsa enjene, tse ileng tsa fihla moo ho tsoa ho turbocharger kapa enjene e tukang ka hare. Botšo bo bontša ho lutla ha moea, ha khase e tšoeu ea exhaust e bonts'a mokelikeli o koalehileng oa oli ea turbocharger.
2. Lebaka letsa molodi ke ho dutla ha moya mateanong a sehokelo sa konpressor le enjene, mme rattle e bonts'a likarolo tsa ho hohla tsa sistimi eohle ea turbocharging.
3. Hape ho bohlokoa ho hlahloba likarolo tsohle tsa turbine enjene e tukang e ka hare, haeba ho joalo li-discs kapa esita le a emisa ho sebetsa.

90% ea mathata a turbine ea enjine a amana le oli.

Bohareng ba bohle ho se sebetse hantle ha turbocharger - mabaka a mararo

Khaello le khatello e tlase ea oli

e hlaha ka lebaka la ho lutla kapa ho pinching ha li-hoses tsa oli, hammoho le ka lebaka la ho kenngoa ha tsona ho fosahetseng ho turbine. E lebisa ho eketseha ha mehele, molala oa shaft, lubrication e sa lekaneng le ho futhumala ho feteletseng ha li-radial bearings tsa turbine. Ba tla tlameha ho fetoloa.

Metsotsoana e 5 ea ts'ebetso ea turbine ea diesel ntle le oli e ka baka tšenyo e ke keng ea lokisoa yuniti eohle.

Tšilafalo ea oli

E etsahala ka lebaka la ho nkeloa sebaka ka nako e sa lekanyetsoang ha oli ea khale kapa filthara, ho kenella ha metsi kapa mafura ka har'a lubricant, tšebeliso ea oli ea boleng bo tlase. E lebisa ho roala, ho koala likanale tsa oli, ho senya axle. Likarolo tse nang le bothata li lokela ho nkeloa sebaka ke tse ncha. Oli e teteaneng e boetse e senya li-bearings, kaha e boloka le ho fokotsa ho tiea ha turbine.

Ntho e tsoang kantle ho naha e kenang ho turbocharger

E lebisa ho senyeha ha mahare a lebili la compressor (ka hona, khatello ea moea e theoha); mabili a turbine; rotor. Ka lehlakoreng la compressor, o hloka ho khutlisa filthara 'me u hlahlobe pampitšana ea ho kenya hore na e lutla. Ka lehlakoreng la turbine, ho bohlokoa ho nkela shaft sebaka le ho sheba mefuta e mengata ea ho kenya.

Sesebelisoa sa turbine ea mochine o tukang ka hare oa koloi: 1. lebili la compressor; 2. ho jara; 3. actuator; 4. phepelo ea oli; 5. rotor; 6. khatriji; 7. khofu e chesang; 8. khofu e batang.

Na hoa khoneha ho lokisa turbine ka bouena?

Sesebelisoa sa turbocharger se bonahala se le bonolo ebile se otlolohile. 'Me sohle se hlokahalang ho lokisa turbine ke ho tseba mohlala oa turbine, nomoro ea enjene, hammoho le moetsi le ho ba le likarolo tse ling kapa lisebelisoa tsa ho lokisa fektheri bakeng sa li-turbine tse teng.

U ka khona ho etsa tlhahlobo ea pono ea turbocharger ka boithaopo, ua e qhaqha, ua e qhaqha le ho nkela likarolo tse sa sebetseng tsa turbine sebaka, ebe u e kenya sebakeng sa eona. Lekola moea, mafura, pholileng le litsamaiso tsa oli tseo turbine e sebelisanang haufi-ufi le tsona, hlahloba ts'ebetso ea tsona.

Thibelo ea ho hloleha ha turbine

Ho eketsa bophelo ba turbocharger, latela melao ena e bonolo:

1. Fetola lihloela tsa moea khafetsa.
2. Tlatsa oli ea pele le mafura a boleng bo holimo.
3. Ka ho feletseng fetola oli tsamaisong ea turbocharging ka mor'a lik'hilomithara tse likete tse 7 sebaka.
4. Sheba khatello e ntseng e eketseha.
5. Etsa bonnete ba hore u futhumatsa koloi ka enjene ea diesel le turbocharger.
6. Ka mor'a ho khanna nako e telele, tlohela enjene e chesang hore e phomole ka ho emisa bonyane metsotso e 3 pele u e tima. Ho ke ke ha e-ba le li-deposit tsa carbon tse tla senya li-bearings.
7. Kamehla etsa diagnostics le ho hlokomela tlhokomelo ea litsebi.
