Isangqa sepiston.
Indandatho yePiston (iRingi yePiston) isetyenziselwa ukufaka umngxuma wepiston ngaphakathi kwendandatho yesinyithi, iringi yepiston yahlulwe yaba ziintlobo ezimbini: iringi yoxinzelelo kunye neringi yeoyile. Iringi yoxinzelelo ingasetyenziselwa ukuvala igesi yomxube ovuthayo kwigumbi lokutsha; Iringi yeoyile isetyenziselwa ukukrazula ioyile engaphezulu kwisilinda. Iringi yepiston luhlobo lwendandatho yesinyithi elastiki ene-deformation enkulu yangaphandle, ehlanganiswe kwiprofayili kunye nomngxuma wayo ojikelezayo ohambelanayo. Iindandatho zepiston ezijikelezayo nezijikelezayo zixhomekeke kumahluko woxinzelelo lwegesi okanye ulwelo ukwenza uphawu phakathi kwesangqa sangaphandle seringi kunye nesilinda kunye necala elinye leringi kunye nomngxuma weringi.
Umsebenzi weringi yepiston uquka ukutywina, ukulawula ioyile (ulawulo lweoyile), ukuqhuba ubushushu (ukudluliselwa kobushushu), isikhokelo (inkxaso) iindima ezine. Ukutywina: kubhekisa ekutywineni igesi, musa ukuvumela igesi yegumbi lokutsha ivuza iye kwi-crankcase, ukuvuza kwegesi kulawulwa ubuncinci, kuphucule ukusebenza kakuhle kobushushu. Ukuvuza komoya akuyi kunciphisa kuphela amandla enjini, kodwa kuya kwenza nokuba ioyile yonakale, umsebenzi ophambili weringi yegesi; Lungisa ioyile (ulawulo lweoyile): ioyile yokuthambisa engaphezulu eludongeni lwesilinda iyakhuhla, kwaye udonga lwesilinda lugqunywe ngefilimu yeoyile encinci ukuqinisekisa ukuthambisa okuqhelekileyo kwesilinda kunye nepiston kunye neringi, umsebenzi ophambili weringi yeoyile. Kwiinjini zanamhlanje ezinesantya esiphezulu, ingqalelo ekhethekileyo inikwa indima yefilimu yeoyile yokulawula iringi yepiston; Ukuqhutywa kobushushu: ubushushu bepiston budluliselwa kwi-cylinder liner ngeringi yepiston, oko kukuthi, isiphumo sokupholisa. Ngokwedatha ethembekileyo, i-70 ~ 80% yobushushu obufunyenwe ngentla yepiston yepiston engapholiyo isasazeka ngeringi yepiston ukuya eludongeni lwesilinda, kwaye i-30 ~ 40% yepiston yokupholisa isasazeka ngeringi yepiston ukuya eludongeni lwesilinda; Inkxaso: Iringi yepiston igcina ipiston kwisilinda, ithintela ukudibana ngqo phakathi kwepiston nodonga lwesilinda, iqinisekisa ukuhamba kakuhle kwepiston, inciphisa ukumelana nokungqubana, kwaye ithintela ipiston ekubetheni isilinda. Ngokubanzi, ipiston yenjini yepetroli isebenzisa imijikelo yegesi emibini kunye neringi yeoyile enye, ngelixa injini yedizili idla ngokusebenzisa imijikelo yeoyile emibini kunye neringi yegesi enye.
Indlela echanekileyo yokufaka indandatho yepiston yile ilandelayo:
1. Kufuneka kuqala ufake indandatho yeoyile, uze ufake indandatho yegesi, iodolo isezantsi ukuya phezulu;
2. Xa kufakwa iringi nganye, ukuvulwa kweringi yepiston akufuneki kwandiswe kakhulu, kwanele nje ukungena kwipiston;
3. Faka iringi yeoyile edibeneyo:
Faka iringi ye-liner kwi-groove yeoyile yepiston, qaphela ukuba ukuvuleka kweringi ye-liner akunakugqithana; Faka iipleyiti zentsimbi ezisezantsi nezingaphezulu ngaphandle kokusebenzisa izixhobo ukuvula izithuba. Xa ufaka, qala ubambe elinye icala lepleyiti yentsimbi esezantsi kwindawo yeringi, cinezela indawo yokuvula ipleyiti yentsimbi ngobhontsi wakho, slayida ubhontsi wesinye isandla kwindawo yeringi ecaleni kwepleyiti yentsimbi, uze ulayishe ipleyiti yentsimbi ephezulu ngendlela efanayo. Musa ukufaka iipleyiti zentsimbi eziphezulu nezisezantsi kwelinye icala leringi ye-liner; Ukuze uphephe ukugqithana okunokwenzeka kwezithuba zeringi ye-liner xa i-piston ityhalelwa kwisilinda, hambisa izithuba zepleyiti eziphezulu nezisezantsi ngamalunga eringi ye-liner ngama-degree angama-90 ukuya kwi-120. Emva kokufakela, jikisa kancinci iringi yeoyile edibeneyo ngesandla, kwaye kufuneka igude ngaphandle kokunamathela.
4. Ufakelo lweringi yegesi:
Sebenzisa izixhobo ezikhethekileyo ukufaka iiringi ezimbini zegesi kunye neringi enye yegesi ngokulandelelana, ungajiki iringi yokuqala yegesi kunye neringi yesibini yegesi; Xa ifakiwe, icala liphawulwe (HYR, HY, CSR, TLK, ALS, H, R, njl.njl.). Kufuneka ijonge phezulu (icala lepiston); Yithi shwaka imbobo yeringi yegesi kwiidigri ezili-180, ungajiki imbobo iye kwicala lepiston pin.
5. Ngaphambi kokuhlanganisa iringi yepiston kwisilinda, kuyimfuneko ukulungisa indawo yokuvula iringi nganye yepiston.
Umsebenzi weringi yepiston:
1. Isiphumo sokutywina
Indandatho yepiston ingagcina itywina phakathi kwepiston nodonga lwesilinda, kwaye ukuvuza kulawulwa ubuncinane, okuthwalwa yindandatho yegesi. Ingathintela isilinda kunye nepiston okanye isilinda kunye nendandatho yepiston ngenxa yokuvuza komoya phakathi kokuluma; Ingathintela nokungaphumeleli okubangelwa kukonakala kweoyile yokuthambisa.
Inyathelo lesi-2: Qhuba ubushushu
Indandatho yepiston inokudlulisa kwaye isasaze ubushushu obuphezulu obuveliswa kukutsha ukuya eludongeni lwesilinda, kwaye inokudlala indima ekupholiseni ipiston.
3. Umsebenzi wokulawula ioyile
Indandatho yepiston ingakrwela ioyile yokuthambisa enamathele eludongeni lwesilinda ukuze igcine ukusetyenziswa kweoyile okuqhelekileyo, okuthwalwa yindandatho yeoyile.
4. Isiphumo sokuxhasa
Indandatho yepiston inyuka isiya phezulu kwisilinda, kwaye umphezulu wayo otyibilikayo uthwalwa ngokupheleleyo yindandatho yepiston, nto leyo ethintela ipiston ekunxibelelaneni ngqo nesilinda kwaye idlala indima yokuxhasa.
Kukho iintlobo ezimbini zeeringi zepiston: iiringi zegesi kunye neeringi zeoyile. Iringi yegesi isetyenziselwa ukuqinisekisa ukuba itywina phakathi kwepiston kunye nesilinda kunye nokuvala umoya ocinezelweyo kwigumbi lokutsha. Iringi yeoyile isetyenziselwa ukukrazula ioyile engaphezulu kwisilinda, nto leyo enokuthintela ioyile ukuba ingaphumi kwisilinda ize itshise.
