Isangqa sepiston.
Indandatho yepiston isetyenziselwa ukufaka umngxuma wepiston ngaphakathi kwendandatho yesinyithi, indandatho yepiston yahlulwe yaba ziintlobo ezimbini: indandatho yoxinzelelo kunye nendandatho yeoyile. Indandatho yoxinzelelo ingasetyenziselwa ukuvala igesi yomxube ovuthayo kwigumbi lokutsha; Indandatho yeoyile isetyenziselwa ukukrazula ioyile engaphezulu kwisilinda. Indandatho yepiston luhlobo lwendandatho yesinyithi elastiki ene-deformation enkulu yangaphandle, ehlanganiswe kwiprofayili kunye nomngxuma wayo ojikelezayo ohambelanayo. Indandatho yepiston ejikelezayo nejikelezayo ixhomekeke kumahluko woxinzelelo lwegesi okanye ulwelo ukwenza uphawu phakathi kwesangqa sangaphandle sendandatho kunye nesilinda kunye necala elinye lendandatho kunye nomngxuma wendandatho.
Ububanzi besicelo
Iiringi zepiston zisetyenziswa kakhulu kwiindidi ezahlukeneyo zoomatshini bamandla, ezifana neenjini zomphunga, iinjini zedizili, iinjini zepetroli, iicompressor, ii-hydraulic presses, njl., ezisetyenziswa kakhulu kwiimoto, oololiwe, iinqanawa, iinqanawa njalo njalo. Ngokubanzi, iringi yepiston ifakwe kwi-ring groove yepiston, kwaye yona kunye nepiston, i-cylinder liner, intloko yesilinda kunye nezinye izinto zegumbi zenza umsebenzi.
Indandatho yepiston yinxalenye ephambili ngaphakathi kwenjini yepetroli, yona kunye nesilinda, ipiston, udonga lwesilinda kunye ukuze kugqitywe ukuvalwa kwegesi yepetroli. Iinjini zeemoto ezisetyenziswa rhoqo zineentlobo ezimbini zeenjini zedizili kunye nepetroli, ngenxa yokusebenza kwazo okwahlukileyo kwepetroli, ukusetyenziswa kwendandatho yepiston akufani, indandatho yepiston yokuqala yenziwa ngokuphosa, kodwa ngenkqubela phambili yetekhnoloji, indandatho yepiston enamandla aphezulu yazalwa, kwaye ngomsebenzi wenjini, iimfuno zokusingqongileyo ziyaqhubeka nokuphucula, iintlobo ngeentlobo zezicelo zonyango lomphezulu ophezulu, ezifana nokutshiza ngobushushu, ukufakelwa kwe-electroplating, ukufakwa kwe-chrome, njl. I-nitriding yegesi, ukufakwa komzimba, ukugqunywa komphezulu, unyango lwe-zinc manganese phosphating, njl., kuphucula kakhulu umsebenzi wendandatho yepiston.
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.
Ukuchongwa okuhle nokubi
Umphezulu osebenzayo weringi yepiston akufuneki ube namaqhuqhuva, imikrwelo, ukuxobuka, isilinda sangaphandle kunye nomphezulu ophezulu nosezantsi kufuneka ube nokugqitywa okuzinzileyo, ukuphambuka kwegophe akufuneki kube ngaphezulu kwe-0.02-0.04 mm, ukuhla okuqhelekileyo kweringi kwindawo ejikelezileyo akufuneki kudlule kwi-0.15-0.25 mm, kwaye ukuthamba kunye nokuvuleka kweringi yepiston kuyahlangabezana neemfuno. Ukongeza, kufuneka sijonge nokuvuza kokukhanya kweringi yepiston, oko kukuthi, iringi yepiston ithe tyaba kwisilinda, sibeke isibane esincinci phantsi kweringi yepiston, sibeke isikrini sokukhanya ngaphezulu, size sijonge umsantsa wokuvuza kokukhanya phakathi kweringi yepiston kunye nodonga lwesilinda, okubonisa ukuba unxibelelwano phakathi kweringi yepiston kunye nodonga lwesilinda lulungile na. Kwiimeko eziqhelekileyo, umthungo wokuvuza kokukhanya kweringi yepiston olinganiswe ngegeyiji yobukhulu akufuneki udlule kwi-0.03 mm. Ubude bomthungo wokuvuza okuqhubekekayo akufuneki bube ngaphezu kwe-1/3 yobubanzi besilinda, ubude benani lezithuba zokuvuza okukhanyayo akufuneki bube ngaphezu kwe-1/3 yobubanzi besilinda, kwaye ubude benani leempazamo zokuvuza okukhanyayo akufuneki bube ngaphezu kwe-1/2 yobubanzi besilinda, kungenjalo, kufuneka kutshintshwe. Uphawu lwendandatho yepiston GB/T 1149.1-94 lucacisa ukuba zonke iindandatho zepiston ezifunekayo ukuze zibe nesikhokelo sokufakelwa maziphawulwe kwicala eliphezulu, oko kukuthi, icala elikufutshane negumbi lokutsha. Iindandatho eziphawulwe kwicala eliphezulu ziquka: iringi yekhoni, i-chamfer yangaphakathi, iringi yetafile yokusika yangaphandle, iringi yempumlo, iringi ye-wedge kunye neringi yeoyile efuna indlela yokufakelwa, kwaye icala eliphezulu leringi liphawulwe.
