I-Los amasongo enjini noma izindandatho ngokuyisisekelo abanye izingxenye zensimbi ezifakwa Slots ezenziwe ku ipiston. Ngenxa yabo, izinjini zinokuqina okwanele emakamelweni avuthayo ukuze zisebenzise ukuqhuma okwenzeka kuzo futhi ngaleyo ndlela zikhiqize ukunyakaza.
Kumamodeli amanje kukhona okujwayelekile okungu-3: amabili awo angama izindandatho zokucindezela nelokugcina indandatho ye-oil scraper. Noma kukhona ukucupha okuhluke kakhulu kuye ngohlobo lwenjini. Isibonelo, ezinjinini ezine-stroke ezimbili kuvame ukuba nezindandatho ezimbili zokucindezela, ngenxa yohlobo lokugcotshwa abanalo.
Izinhlobo zamasongo e-piston nemisebenzi yawo
ingxenye yokucindezela
I-Los izindandatho zokucindezela, ebizwa nangokuthi amasongo omlilo, abaphethe vala amakamelo omlilo. Ngale ndlela, ingxube ye-air-fuel ayidluli ku-crankcase ngesikhathi isigaba sokucindezela somjikelezo wenjini, futhi namagesi avuthayo awenzi ngesikhathi sezigaba zokunwetshwa nokukhipha umoya.
Omunye wemisebenzi yakhe uku dlulisa ingxenye yokushisa kusukela ku-piston kuya ezindongeni ze-cylinder, ngesikhathi injini isebenza. Lokhu kusiza ukusabalalisa izinga lokushisa ngokulinganayo futhi kukhiphe ukushisa okuthile ekhanda lepiston. Futhi, futhi isebenza njenge-buffer Ngezinga elithile. Kumele zenziwe nge-carbon steel eqinile kakhulu kodwa enezimbotshana ngesikhathi esifanayo.
ingxenye ye-scraper
El indandatho ye-oil scraper, Ngokwesinye isandla, ivumela ukuthi amanye amafutha adlule phezulu kwesilinda futhi susa okweqile ngokushanela. Ngaso leso sikhathi, iphinde ikhuhle isithambisi esinamathela phansi kwesilinda kusukela ekuchaphazeni okudalwa ukunyakaza kwenjini.
Ezimweni eziningi, ingxenye ye-scraper yenziwe ngezingcezu eziningana. bangu ngezindandatho ezimbili: indandatho ephindwe kabili ene-groove phakathi lapho kuzofakwa khona indandatho yesibili emise okwe-helical. futhi zikhona ngezindandatho ezintathu: eyodwa ebizwa ngokuthi i-expander ring, enomumo wegagasi ukuze idale umphumela wasentwasahlobo, namasongo amabili ensimbi azacile, enye ngaphezu kwayo nenye ngaphansi kwayo.
indandatho ye-expander
Njengoba sesishilo ngaphambili, lolu hlobo lwezicucu igcwalisa ezinye izingxenye. Iyindandatho emise okwegagasi, efakwa emseleni ohambisana nawo kuqala. Ngemva amasongo okunwaya afakwa kuso ezihambisanayo, ezibekwe ngokumelene nodonga lwesilinda ngenxa yomphumela wasentwasahlobo we-expander.
I-Podemos hlukanisa zombili izinhlobo zamasongo ngokubukeka, ngoba ezicindezelayo zibushelelezi, ukugwema izimbobo lapho ingcindezi iphuma khona. Esikhundleni salokho, izindandatho ze-oil scraper zinezimbobo endaweni yazo ukuze kube lula ukusatshalaliswa okulinganayo kwe-lubricant (indandatho eyandisayo).
Inombolo kanye nendawo yamasongo e-piston
Amaringi e-Piston nokubekwa kwawo enjinini engu-2t
Izingxenye zenjini enama-stroke amabili (2t) ngokuvamile kukhona ezimbili kuphela ezinikezelwe cindezela. Lokhu kungenxa yokuthi okokugcoba kuxutshwe nomoya kanye nophethiloli futhi, ngaphambi kokufika egumbini elivuthayo, uhamba nge-crankcase, the i-camshaft, izinduku zokuxhuma… kanye namapiston avela ngezansi. Ngendlela yokuthi bahlale begcotshiwe ngaphandle kwesidingo sokudonsa izindandatho ezisakaza amafutha ezindongeni. Isibonelo, yile ndlela amasongo e-piston e-49 cc moped abukeka ngayo.
Amaringi e-Piston nokubekwa kwawo enjinini engu-4t
Ezinjinini ezine-stroke (4t) okuvame kakhulu ukuthola izingxenye ezimbili zokucindezela ukuthi hamba phezulu futhi ukuklwebheka okukodwa ngezansi. Njengoba sike sabonisa ngaphambili, lokhu kokugcina kuvame ukwakhiwa ngendandatho ye-expander nama-scrapers amabili ensimbi.
emakhithi of piston izindandatho ukuhleleka okuqondile kuvame ukukhonjiswa lapho okufanele zibekwe khona. Kumele landela imiyalelo yemodeli yakho ngokucophelela. Nokho, ukuqoqwa okujwayelekile kungokulandelayo:
- indandatho ephezulu: a indandatho ye-chrome esebenza njengophawu ngokumelene nokucindezela okukhulu okukhiqizwa kusilinda. Ukufakwa kwe-chrome kusebenza ukumelana namazinga okushisa aphezulu.
- Indandatho emaphakathi: a indandatho emnyama ngenxa yokwembozwa kwe-zinc phosphate. Isebenza ukulawula uwoyela nokusiza i-chrome ukuthi ivale isilinda.
- indandatho yaphansi: izindandatho zokugcina ukuthambisa okwanele kwepiston.
Siphinde sikubonise ividiyo lapho ungabona khona ukuthi lezi zingxenye zinjani, ukuthi ukusatshalaliswa kwazo kuyini ku-piston futhi kulula kangakanani ukuzifaka. Ngayinye inendlela yayo yokuyifaka kanye nokuma kwayo ukuze ifeze umsebenzi wayo:
Ungazi kanjani ukuthi iringi yonakele
Inqubo evamile ukubeka ingxenye esizoyihlola ngaphakathi kwesilinda. Kufanele ibe evundlile ngokuphelele, ngakho-ke ibe ngcono zisize nge-caliber ukuze ibekwe ngokuphelele. Khona-ke kufanele nje ubone ukuthi iziphetho zesigaba zikude kangakanani komunye nomunye. Ukuze wenze lokhu ungasebenzisa ama-gauge wokulinganisa, njengalawo we Ubuchwepheshe be-BGS noma lezo ze ama-kinstecks, nakuba noma yini efanayo izokwenza.
Kulokhu ividiyo uyabona ukuthi zenziwa kanjani amasheke ahambisanayo enziwe lula, ukwazi ukuthi ungashintsha nini izingxenye. Umsebenzi osaqhubeka wenziwe ezithuthuthwini noma emishinini, kodwa ongakaze wenziwa ezinjinini zezimoto amashumi eminyaka.
U-Mariano:
Mhlawumbe lokhu kuyimpikiswano, kodwa okubalulekile ukufinyelela esiphethweni ngokucabanga kobuchwepheshe.
Indandatho yokuqala, njengoba ushilo, yaziwa ngokuthi yindandatho yomlilo futhi iyindandatho yokucindezela futhi ezimweni eziningi inongqimba lwe-chrome eqinile noma efanayo emaphethelweni ayo (indawo yokungqubuzana ne-cylinder).
Indandatho eshanela ingxenye enkulu yamafutha afakwa kumasilinda iyindandatho yesibili, nayo enomthelela ekuvaleni.
Iringi yesithathu, ngokuvamile eyakhiwe ngeziqephu ezingaphezu kwesisodwa, iyindandatho yokugcoba, ephethe ukufakwa kwamafutha agcobisa amasilinda.
Ngiphinde ngakutshela ukuthi nakuba zikhona izindandatho zensimbi, kukhona ne-centrifugal ne-nodular cast iron.
Sawubona!
Umuntu angangitshela ukuthi, ezinjinini ezi-2-stroke lapho ngokuyisisekelo kunezinhlobo ezi-2 zamalayini: insimbi empunga ne-chrome (noma i-nikasil), izindandatho zihlala zihlukile, okungukuthi, ama-cast iron liners angaba namasongo ensimbi , noma izindandatho ezi-chromed kuphela?, namahembe e-nikasil, yiziphi izinhlobo zamasongo?, i-chromed noma i-cast iron...
Ngiyabonga:
Sanibonani, ngabe kukhona owaziyo ukuthi indandatho inamuphi umuthi wokushisisa ngemuva kokwenziwa ngomshini, nginezintambo ezimbalwa engizenzile izindandatho kodwa angazi ukuthi inayiphi indlela yokushisa, into engiyisebenzisayo i-pearlite grey cast iron.
umlilo owodwa ubekwe ngaphansi kwawo wonke kanti amanye amabili abekwe ngaphezulu
sawubona samir ngine r1 engahlomile enehembe likasil eliqhekekile, futhi ayingeni as a spare part e arg, utshela wonke umuntu, ngicela ukubuza uma ngifaka amahembe ensimbi anamahuphu enikasil, kwenzekani? Ngiyabonga
USamir uyihlaya, akunjalo?
Umqhele we-piston ukhala ngohlelo olwehlayo, okungukuthi ukusuka phezulu kuye phansi:
1- Of Fire noma Compression.
I-2- Scraper (Leyo eyenza amafutha adlule abheke engxenyeni engenhla noma engezansi).
3- Ukuthambisa. (Susa uwoyela ongadingekile futhi.)
Ngiyethemba ngisize. Zama ukuzibeka ngokuhlelekile noma uzogcina usushisa "i-cylinder cover gasket" (Ingxenye Yomlilo engewona umlilo futhi yingakho ivutha) ye-renault cangoo.
A ukubingelela.
Imithombo: I-Stark Industries 😀
Hlola ukuthi izindandatho zibekwe ngendlela efanele yini, indandatho yokuqala evamile yokucindezela okubushelelezi ingaba chrome noma emnyama, indandatho yesibili ebushelelezi ye-oil-scraper eshanela izindonga ze-cylinder ebangela ukuba uwoyela wehle, indandatho yesithathu neyokugcina iyisiphethu esingena umoya noma i-barflex. , okungamashidi amabili kanye nesibungu ... kungenzeka ukuthi unendandatho yokuqala emgodini wesibili kanye nendandatho yesibili emseleni wokuqala, futhi ubangela ukushisa okukhulu kanye nokuqhuma kwamalunga, kungenjalo kungase kube. inkinga ngejoyinti...
kulungile ngokukhathazeka, amasegimenti noma izindandatho zama-pistons (ama) pistons zihamba ngokulandelana ukusuka phezulu kuye phansi 1st 2st of fire (compression), 3nd scraper (i-oil scraper) lapha ngifuna ukubuza umbuzo lendandatho ivumela inani elincane amafutha ukuze ashise ngokuvutha phezulu kwesilinda kunoma yiziphi izigaba zawo noma izigaba ezithile (ukucindezela, ukuphuma) noma kuzo zonke, ngiyaqonda ukuthi amafutha avela ku-crankcase phezulu noma angaphezulu kwekamelo lapho ama-valve ahamba, icamshaft kunezimbobo zokuthi inani elithile likawoyela lingene kusilinda (ngiyazi ukuthi ukuze umsebenzi ube khona kusilinda kumele kube nomoya, uphethiloli kanye nenhlansi, KODWA AKUKHO MAFUTHA noma inani elincane lamafutha. ) kanye neringi yesi-XNUMX esesimweni sesibungu noma engaqondile iyona ehlanza ngempela uwoyela lapho ipiston isesigabeni sokwamukelwa …….. ngiyabonga kakhulu futhi ngiyaxolisa ngesigaba
kulungile ngenxa yokukhathazeka, amasegimenti noma izindandatho zama-pistons zihamba ngokulandelana ukusuka phezulu kuye phansi kwendandatho yoku-1 yomlilo (ukucindezela), indandatho yesi-2 (i-oil scraper) lapha ngifuna ukubuza umbuzo lendandatho ivumela inani elincane amafutha ukuze ashise ngokuvutha phezulu kwe-cylinder kunoma yiziphi izigaba zayo noma izigaba ezithile (ukucindezela, ukuphuma) noma kuzo zonke, ngiyaqonda ukuthi amafutha avela ku-crankcase phezulu noma angaphezulu kwekamelo lapho ama-valve ahamba, icamshaft kunezimbobo zokuthi inani elithile lamafutha lingene ku-cylinder (ngiyazi ukuthi ukuze umsebenzi ube khona kusilinda kufanele kube nomoya, uphethiloli kanye nenhlansi, KODWA HHAYI MAFUTHA noma inani elincane lamafutha. ) kanye neringi yesi-3 esesimweni sesibungu noma engaqondile iyona ehlanza ngempela uwoyela lapho ipiston isesigabeni sokwamukelwa …….. ngiyabonga kakhulu futhi ngiyaxolisa ngesigaba
Ungangitshela amakilasi ama-hoops noma amaringi
Futhi yiziphi izinhlobo ze-hoops noma izindandatho
