Umsesane wepiston.
I-Piston Ring (Piston Ring) isetyenziselwa ukushumeka i-piston groove ngaphakathi kwentsimbi yentsimbi, iringi yepiston yahlulwe ibe ziindidi ezimbini: iringi yokucinezela kunye neringi yeoli. Iringi yoxinzelelo ingasetyenziselwa ukutywina igesi yomxube ovuthayo kwigumbi lokutsha; Iringi yeoli isetyenziselwa ukukhuhla ioyile engaphezulu kwicylinder. Umsesane wepiston luhlobo lweringi yentsimbi eneelastiki ene-deformation enkulu yangaphandle, ehlanganiswe kwiprofayili kunye ne-groove ehambelana nayo. Amakhonkco episton abuyelayo kunye ajikelezayo axhomekeke kumahluko woxinzelelo lwerhasi okanye ulwelo ukwenza itywina phakathi kwesangqa sangaphandle sesangqa kunye nesilinda kunye necala elinye lomsesane kunye negroove yeringi.
Umsebenzi we-piston ring uquka ukutywinwa, ukulawula ioli (ulawulo lweoli), ukuqhuba ukushisa (ukudluliselwa kobushushu), isikhokelo (inkxaso) iindima ezine. Ukutywinwa: kubhekiselele kwigesi yokutywina, musa ukuvumela igumbi lokutshisa igesi evuzayo kwi-crankcase, ukuvuza kwegesi kulawulwa ubuncinane, kuphucula ukusebenza kakuhle kwe-thermal. Ukuvuza komoya akuyi kunciphisa kuphela amandla e-injini, kodwa kwakhona kwenza ukuwohloka kweoli, owona msebenzi oyintloko wendandatho yegesi; Lungisa ioyile (ulawulo lweoyile) : Ioyile yokuthambisa egqithileyo eludongeni lwesilinda ichithwe, kwaye udonga lwesilinda lugqunywe ngefilimu yeoli encinci ukuqinisekisa ukuthambisa okuqhelekileyo kwecylinder kunye nepiston kunye neringi, owona msebenzi uphambili iringi yeoli. Kwiinjini zanamhlanje zesantya esiphezulu, ingqwalasela ekhethekileyo ihlawulwa kwindima yefilimu ye-oyile yokulawula i-piston; Ukuqhutyelwa kokushisa: ukushisa kwepiston kudluliselwa kwi-cylinder liner ngokusebenzisa i-piston ring, oko kukuthi, umphumo wokupholisa. Ngokutsho kwedatha ethembekileyo, i-70 ~ 80% yobushushu obufunyenwe yi-piston top of the piston engapholiswanga ihlakazwa ngendandatho yepiston kudonga lwesilinda, kwaye i-30 ~ 40% yepiston yokupholisa ihlakazwe ngeringi yepiston ukuya kwi-cylinder. udonga; Inkxaso: Iringi yepiston igcina ipiston kwi-cylinder, inqanda ukudibana ngokuthe ngqo phakathi kwepiston kunye nodonga lwesilinda, iqinisekisa ukuhamba kakuhle kwepiston, inciphisa ukuxhathisa ukukhuhlana, kwaye inqanda ipiston ekubetheni i-cylinder. Ngokubanzi, ipiston ye-injini yepetroli isebenzisa amakhonkco amabini erhasi kunye neringi yeoli enye, ngelixa injini yedizili ihlala isebenzisa amakhonkco e-oyile amabini kunye neringi yerhasi enye.
Indlela yofakelo echanekileyo yeringi yepiston yile ilandelayo:
1. Okokuqala kufuneka ufake i-oil ring, ngoko i-gas ring, umyalelo uphantsi-phezulu;
2. Xa ikhonkco ngalinye lifakwe, ukuvulwa kwentsimbi yepiston akufanele kwandiswe kakhulu, ngokwaneleyo ukuba ingene kwipiston;
3. Faka iringi yeoli edibeneyo:
Faka i-liner ring kwi-piston oil ring groove, nikela ingqalelo ekuvuleni umsesane we-liner awukwazi ukugqithelana; Faka iipleyiti zentsimbi ezisezantsi nangaphezulu ngaphandle kokusebenzisa izixhobo zokuvula izivulo. Xa ufaka, qala ubambe isiphelo sepleyiti yentsimbi esezantsi kwindawo yokubeka intsimbi, cofa indawo yokuvula ipleyiti yentsimbi ngobhontsi wakho, tyibilikisa ubhontsi wesinye isandla kwintsimbi yeringi ecaleni kwepleyiti yentsimbi, emva koko ulayishe ipleyiti yentsimbi ephezulu ngendlela efanayo. Musa ukufaka iiplati zetsimbi eziphezulu kunye nezantsi kwelinye icala lomsesane welinen; Ukunqanda ukuhlangana okunokwenzeka kwekhonkco le-liner xa i-piston ityhilwa kwi-cylinder, gxadaza iindawo ezivulekayo eziphezulu kunye nezisezantsi kunye nezihlanganisi zeringi ngama-90 ukuya kwi-120 degrees. Emva kokufakela, ujikeleze ngobumnene i-oyile edibeneyo ngesandla, kwaye kufuneka ihambe kakuhle ngaphandle kokubambelela.
4. Ufakelo lweringi yerhasi:
Sebenzisa izixhobo ezikhethekileyo zokufakela amakhonkco amabini egesi kunye nentsimbi yegesi enye, musa ukuguqula intsimbi yokuqala kunye neyesibini; Xa ifakwe, icala liphawulwe (HYR, HY, CSR, TLK, ALS, H, R, njl.). Kufuneka ujonge phezulu (i-piston head direction); Ukugxadazela ukuvuleka komsesane werhasi ngee-degrees ezingama-180, ungajiki uvula kwicala lepiston.
5. Ngaphambi kokudibanisa i-piston ring kwi-cylinder, kuyimfuneko ukulungelelanisa indawo yokuvula ikhonkco nganye yepiston.
Umsebenzi weringi wepiston:
1. Isiphumo sokutywinwa
Umsesane wepiston unokugcina itywina phakathi kwepiston kunye nodonga lwe-cylinder, kwaye ukuvuza kulawulwa ubuncinci, obuthwalwa yintsimbi yegesi. Inokuthintela isilinda kunye nepiston okanye isilinda kunye neringi yepiston ngenxa yokuvuza komoya phakathi kokuluma; Kwakhona kunokuthintela ukusilela okubangelwa kukonakala kweoli yokuthambisa.
Inyathelo lesi-2 Ukuqhuba ubushushu
Iringi yepiston inokudlulisa kwaye isasaze ubushushu obuphezulu obuveliswe kukutsha kudonga lwesilinda, kwaye inokudlala indima ekupholiseni ipiston.
3. Umsebenzi wokulawula i-oyile
Umsesane wepiston unokukrazula ioyile yokuthambisa edityaniswe eludongeni lwesilinda ukuze kugcinwe ukusetyenziswa kweoyile eqhelekileyo, ethwalwa yindandatho yeoli.
4. Isiphumo esixhasayo
Iringi yepiston ihla inyuka inyuka kwi-cylinder, kwaye indawo yayo yokutyibilika ithwalwa ngokupheleleyo ngumsesane wepiston, ukuthintela ipiston ukuba iqhagamshelane ne-cylinder ngokuthe ngqo kwaye idlale indima exhasayo.
Kukho iintlobo ezimbini zemisesane yepiston: imisesane yegesi kunye nemisesane yeoli. Iringi yegesi isetyenziselwa ukuqinisekisa ukutywinwa phakathi kwepiston kunye nesilinda kunye nokutywina umoya oxinzelelweyo kwigumbi lokutsha. Iringi yeoli isetyenziselwa ukukhuhla i-oyile engaphezulu kwi-cylinder, enokuthi ithintele i-oyile ukuba ingaphumi kwi-cylinder kwaye ivutha.
