Piston ea koloi ke eng
Piston ea koloi ke karolo ea mantlha e tsamaeang ka har'a enjene ea ho chesa ka hare e fetolang matla a mocheso hore e be matla a mechini . E fetisetsa khatello ea ho chesa ho crankshaft ka motsamao o pheta-phetoang 'me e nka karolo ho thehoeng ha kamore ea ho chesa.
Youdaoplaceholder0 Litlhaloso tsa mantlha le mesebetsi
Piston ea koloi ke karolo e silindara e kentsoeng ka har'a silindara ea enjene. Mesebetsi ea eona ea mantlha e kenyelletsa:
Youdaoplaceholder0 Phetoho ea matla : Khatello ea khase e hlahisoang ke ho chesoa ha mafura e fetisetsoa ho crankshaft ka phini ea piston le molamu o hokahanyang, e e fetola matla a potolohang.
Youdaoplaceholder0 Sebopeho sa kamore ya ho tuka : Hammoho le hlooho ya silindara le lebota la silindara, e bopa sebaka se kwetsweng sa ho tuka.
Youdaoplaceholder0 Ho hokahanya motsamao : Potoloho ea li-stroke tse 'ne ea ho kenella, ho hatella, tlhahiso ea motlakase le ho ntša mosi e phethoa ka ho hokahanya motsamao o pheta-phetoang.
Youdaoplaceholder0 Sebopeho le thepa ea thepa
Piston e amohela moralo o arohaneng:
Youdaoplaceholder0 top : Lienjene tsa peterole li jara khatello ea ho tuka ka kotloloho, boholo ba tsona li sebelisa sebopeho se bataletseng sa holimo, ha lienjene tsa diesel hangata li entsoe ka likoti ho fihlela litlhoko tsa ho tuka.
Hlooho ea Youdaoplaceholder0 : Karolo ea bohlokoa bakeng sa ho kenya mehele ea piston, e nang le li-groove tsa mehele tse 3 ho isa ho tse 4 (mehele ea khase le mehele ea oli) ho fihlela ho koaloa le ho tlotsoa.
Sekoahelo sa Youdaoplaceholder0: Mosebetsi o tataisang, ho koahela bokaholimo ho fokotsa khohlano, moralo oa sejoale-joale o atisa ho ba "o mokhutšoanyane le o teteaneng" ho ntlafatsa ho tiea le ho qhalana ha mocheso.
Thepa e ka sehloohong ke motsoako oa aluminium, o kopanyang bobebe (ho fokotsa matla a inertial) le khanyetso ea mocheso o phahameng. Mefuta e meng ea ts'ebetso e phahameng e sebelisa nickel plating kapa ceramic coating
Youdaoplaceholder0 Tikoloho ea mosebetsi le liphephetso tsa tekheniki
Lipiston li sebetsa tlas'a maemo a feteletseng:
Youdaoplaceholder0 Mocheso o phahameng le khatello e phahameng : Mocheso o potlakileng oa kamore ea ho tuka o feta 2500K, 'me karolo e ka holimo e lula e na le khatello ea 3-9MPa.
Motsamao o lebelo le phahameng oa Youdaoplaceholder0 : Enjene ea peterole e ka fihla lebelo la ho potoloha la 6000rpm, le tsamaellanang le lebelo le otlolohileng le fetang 20m/s.
Youdaoplaceholder0 Matla a rarahaneng : a tobana le meroalo e amang nako le nako, khatello e ka thoko le phetoho ea khatello ea mocheso.
Lipiston tsa sejoale-joale li ntlafatsa sebopeho sa tsona ka tlhahlobo ea likarolo tse lekanyelitsoeng 'me li amohela boqapi ba theknoloji bo kang liteishene tsa oli tse pholileng le lipeipi tsa ho thibela mocheso ho rarolla mathata ana.
Piston eohle e ka aroloa haholo-holo likarolo tse tharo: karolo e ka holimo ea piston, hlooho ea piston le sekoti sa piston.
Mosebetsi o ka sehloohong oa piston ke ho jara khatello ea ho tuka ka har'a silindara le ho fetisetsa matla ana ho crankshaft ka phini ea piston le molamu o hokahanyang. Ho phaella moo, piston, hammoho le hlooho ea silindara le lebota la silindara, li etsa kamore ea ho tuka.
Karolo e ka hodimo ya piston ke karolo ya kamore ya ho tuka mme hangata e etswa ka dibopeho tse fapaneng. Dienjeneng tsa peterole, karolo e ka hodimo ya piston hangata e nka karolo e bataletseng kapa karolo e ka hodimo e kobehileng ho etsa hore sebopeho sa kamore ya ho tuka se be nyane, sebaka sa ho qhala mocheso se be se senyenyane, mme tshebetso ya tlhahiso e be bonolo. Dipiston tse ka hodimo tse kobehileng hangata di sebediswa dienjeneng tsa peterole tse nang le distroke tse pedi. Karolo e ka hodimo ya piston ya enjene ya diesel hangata e etswa dikoti tse fapaneng.
Hlooho ea piston ke karolo e kaholimo ho setulo sa piston pin. Mehele ea piston e kenngoa hloohong ea piston ho thibela khase e mocheso o phahameng le e nang le khatello e phahameng ho kena ka har'a crankcase le ho thibela oli ea enjene ho kena ka phapusing ea ho tuka. Bongata ba mocheso o monngoang ke karolo e ka holimo ea piston le bona bo fetisetsoa silindareng ka hlooho ea piston ebe bo nkoa ke setsi sa ho pholisa.
Hlooho ea piston e entsoe ka mehele e 'maloa ea lesale bakeng sa ho kenya mehele ea piston. Palo ea mehele ea piston e itšetlehile ka litlhoko tsa ho koala 'me e amana le lebelo la enjene le khatello ea silindara. Palo ea mehele enjeneng e lebelo le phahameng e ka tlase ho ea enjeneng e lebelo le tlase, 'me palo ea mehele enjeneng ea peterole e ka tlase ho ea enjeneng ea diesel. Enjene ea peterole e akaretsang e sebelisa mehele e 'meli ea khase le lesale le le leng la oli. Enjene ea diesel e na le mehele e meraro ea khase le lesale le le leng la oli. Lienjene tsa diesel tse lebelo le tlase li sebelisa mehele ea khase e 3 ho isa ho e 4. Ho fokotsa tahlehelo ea khohlano, bophahamo ba karolo ea annular bo lokela ho theoloa ka hohle kamoo ho ka khonehang. Tlas'a boemo ba ho netefatsa ho koaloa, boiteko bo lokela ho etsoa ho fokotsa palo ea mehele.
Likarolo tsohle tse ka tlase ho mokoti oa lesale la piston li bitsoa li-skirt tsa piston. Mosebetsi oa tsona ke ho tataisa piston ho etsa motsamao o pheta-phetoang ka har'a silindara le ho jara khatello e ka thoko. Ha enjene e ntse e sebetsa, ka lebaka la tšusumetso ea khatello ea khase ka har'a silindara, piston e tla kobeha le ho senyeha. Kamora hore piston e futhumatsoe, hobane ho na le tšepe e ngata piston pin, katoloso ea eona e kholo ho feta ea likarolong tse ling. Ho phaella moo, piston e tla boela e be le phetoho e hatellang tlas'a ketso ea khatello e ka thoko. Sephetho se kopaneng sa liphetoho tse ka holimo se etsa hore karolo e tšelang ea skirt ea piston e be ellipse e nang le axis e telele e otlolohileng ho ea ka lehlakoreng la piston pin. Ho phaella moo, ka lebaka la kabo e sa lekanang ea mocheso le boima ho potoloha axis ea piston, katoloso ea mocheso ea karolo e 'ngoe le e 'ngoe e tšelang e kholo holimo 'me e nyane tlase.
Haeba o batla ho tseba ho eketsehileng, tsoela pele ho bala lihlooho tse ling sebakeng sena sa marang-rang!
Ka kopo re letsetse haeba o hloka dihlahiswa tse jwalo.
