Piston izindandatho - inhloso kanye nezindleko esikhundleni. Yiziphi izimpawu zamasongo ezilimele?

Izinhlobo zendandatho ye-piston

Ukuze uchaze ngokugcwele ukuthi yiziphi izindandatho ze-piston, kubalulekile ukusho izinhlobo zazo. Kunezinhlobo ezilandelayo zamasongo e-piston:

• ukubeka uphawu;
• i-scraper yokucindezela;
• umnwaya

Piston izindandatho - imisebenzi

Inhloso yamasongo e-piston ukuvala isikhala phakathi kwegumbi elivuthayo lenjini kanye ne-crankcase. Baphinde banikeze ukususwa okusebenzayo kowoyela wenjini oweqile ofakwa ezindongeni zesilinda ngesikhathi sokusebenza kwemoto.

Indandatho ye-piston isebenza njengesithwali se-thermodynamic esisusa ukushisa kumapiston. Lokhu kuphinde kuthinte nokulawulwa kokusetshenziswa kukawoyela ngohlelo lokushayela, ngakho-ke kufanele kuqikelelwe ukuthi usesimweni esihle. Kufanele bagcwalise ngokufanelekile indawo yokuvala ukuze igebe elincane ligcwaliswe yisihlungi samafutha. Kuyaphawuleka ukuthi ekukhiqizeni kwabo inqubo ebizwa ngokuthi i-ovalization isetshenziswa. Ikuvumela ukuthi unikeze isakhiwo isimo se-oval, ukwandisa ukuguquguquka kwayo ekwandiseni okushisayo.

Amaringi okuzisholo ngokumelene namaringi amakhulu

Iphutha elivamile ukufaka izindandatho zesitoko kuma-piston amakhulu. Ngisho nokungalungi okuncane ekufakeni kungaholela ekuhlulekeni okukhulu kweyunithi yokushayela kanye nesidingo sokulungiswa kwayo. Ngaso sonke isikhathi khumbula ukufaka izindandatho zesitoko kumapiston esitokisini namasongo amakhulu kunamaphiston anosayizi ofanayo.

Iyiphi indima edlalwa ama-piston rings emotweni?

Uma uzibuza ukuthi iyiphi indima edlalwa amasongo e-piston emotweni, khumbula ukuthi umsebenzi wawo oyinhloko ukuvala indawo phakathi kwegumbi elivuthayo nezindlu. induku yokuxhuma. Lezi zakhi zenziwe ngokunemba okukhulu nangokucophelela, ngakho noma yimuphi umonakalo kuzo kuthinta kabi ukusebenza kwenjini. Ezimotweni ezindala, ukulungiswa kungabiza kakhulu futhi kubangele ukuthi imoto ilahlwe.

Piston izindandatho - izimpawu ukwehluleka

Izimpawu zeringi ye-piston embi yilezi:

• i-flutter yezinto;
• ukulahlekelwa amandla okuphawulekayo;
• ukusetshenziswa kukawoyela ngokweqile. 

Ungabhekana nalezi zinkinga uma ubeka injini yakho kaphethiloli emithwalweni ephakathi nama-RPM aphezulu. Kungakhathalekile ukuthi ingakanani ibanga lemoto noma ubukhulu bokusetshenziswa kwayo, ukungasebenzi kahle kweringi ye-piston kufanele kukukhuthaze ukuthi uvakashele igaraji ngokushesha okukhulu.

Abanjwe amafutha scraper izindandatho - izimpawu

Amandla enjini anciphile awuphawu lokuqala lokunamathela izindandatho zokukhuhla amafutha. Khumbula ukuthi ukwehluleka kwalezi zakhi kuba nomthelela omubi empilweni yenjini. Kungase futhi kube ngenxa yokuguga okusheshayo kwamasilinda. Uma ungaboni noma yikuphi ukungahambi kahle ekusebenzeni kwedrayivu yemoto, kufanele nakanjani ulinganise ingcindezi yokucindezela ngezikhathi ezithile. Ukuxilongwa kwalolu hlobo kufanele kwenziwe njalo ngezinkulungwane ezimbalwa zamakhilomitha. Umehluko phakathi kwemiphumela elandelanayo akufanele udlule i-0,2 MPa.

Kuyini ukushintshwa nokufakwa kwamasongo e-piston?

Ukushintsha nokufaka amasongo e-piston enjinini kudinga ulwazi nolwazi, futhi lokhu kuhlotshaniswa nezindleko ezinkulu. Ukushintsha o-rings ngokuvamile kudinga ukulungiswa kabusha kwenjini. Kumele uqaphele ukuthi imoto yakho izobe ibekwe okungenani isonto lonke. Ububanzi benkonzo ngokuvamile akubandakanyi ukulungiswa kwama-pistons kuphela, kodwa futhi nokugaya izinduku zokuxhuma, ukugaya izihlalo zama-valve kanye nokuhlonishwa kwamasilinda. Ngokukhetha usizo lwabachwepheshe, uzogwema amaphutha, njengokufakwa kakade okukhulunywe ngakho kwamasongo avamile kuma-pistons angalungile. Kumuntu ovamile, lokhu kungase kungabonakali, futhi imiphumela ingaba mnandi. Uma uthintana nesevisi yemoto kusengaphambili, ungagwema ukulungiswa okumba eqolo.

Ungakwazi yini ukufaka ama-piston rings ngokwakho?

Uma uzibuza ukuthi ungazishintsha kanjani izindandatho ze-piston, yazi ukuthi kungenzeka. Kodwa-ke, lokhu kudinga ukufinyelela kuhlu lwamathuluzi namathuluzi wamandla ochwepheshe.. Ukuthenga kwabo akunanzuzo kumshayeli ojwayelekile. Umthamo wolwazi uzophinde ube usizo, uma kuphela ukuze ungenzi iphutha ngokufaka izindandatho ezivamile kuma-pistons amakhulu. Ngokombono wethu, abantu abanolwazi kumishini yezimoto bangase balingeke ukuba bazilungise ngokwabo. Uma kungenjalo, kungcono ukuthatha usizo lochwepheshe.

Kubiza malini ukulungisa iringi yepiston?

Izindleko kuye ngemodeli yemoto ukulungiswa piston izindandatho isukela 1-2 kuya 5-6 ayizinkulungwane zloty. Khumbula ukuthi ukufaka esikhundleni esisodwa kungase kungenele. Ukulungiswa kabusha kwenjini kuyinsizakalo eyaziswa izinkundla zokucobelelana ngolwazi ngemishini ngisho ngamashumi ezinkulungwane. i-zloty. Hlola izinga likawoyela wakho njalo ukuze ugweme ukunakekelwa okumba eqolo.
