Indandatho yepiston.
I-Piston Ring (indandatho yePiston) isetshenziselwa ukushumeka i-piston groove ngaphakathi kwendandatho yensimbi, indandatho ye-piston ihlukaniswe izinhlobo ezimbili: ukucindezelwa kwendandatho kanye nendandatho kawoyela. Indandatho yokucindezela ingasetshenziswa ukubeka uphawu igesi ehlanganisiwe yengxube egumbini lokuhlanganisa; Indandatho kawoyela isetshenziselwa ukuklama uwoyela owengeziwe kwisilinda. Indandatho ye-piston uhlobo lwendandatho yensimbi yensimbi enoguquko olukhulu lwangaphandle lwangaphandle, oluhlangene kuphrofayili kanye ne-groove yayo ehambelana nayo. Izindandatho ze-piston ezivunayo zincike emngcwabeni umehluko wegesi noma uketshezi ukwakha uphawu phakathi kombuthano wangaphandle wendandatho kanye nesilinda kanye ne-groove eyodwa.
Umsebenzi we-Piston Ring ufaka uphawu, ukulawula uwoyela (ukulawula uwoyela), ukushiswa kokushisa (ukudluliselwa kokushisa), ukuholwa (ukwesekwa) izindima ezine. Ukubekwa uphawu uphawu: Kubhekiswa kugesi yokubopha, ungavumeli ukufutheka kwegesi ye-combung to the crankcase, ukuvuza igesi kulawulwa okungenani, thuthukisa ukusebenza kahle okushisayo. Ukuvuza komoya ngeke kunciphise amandla enjini kuphela, kepha futhi kwenza ukonakala kowoyela, okuwumsebenzi ophambili wendandatho yegesi; Lungisa uwoyela (ukulawula uwoyela) Ezinjini zesimanje zesivinini esikhulu, ukunakwa okukhethekile kukhokhwa endimeni yefilimu kawoyela yokulawula i-piston ring; Ukushisa okushisa: Ukushisa kwePiston kudluliselwa ku-liner ye-cylinder ngendandatho yepiston, okungukuthi, umphumela wokupholisa. Ngokwemininingwane ethembekile, ama-70 ~ 80% wokushisa okutholwe yiPiston Top ye-Piston engaxhunyiwe ku-piston ring odongeni lwe-cylinder, futhi 30 ~ 40% wePiston opholile uhlakazeke ngodonga lwe-piston odongeni lwesilinda; Ukusekelwa: Indandatho yePiston igcina ipiston kusilinda, ivimbela ukuxhumana ngqo phakathi kwepiston nodonga lwe-cylinder, iqinisekisa ukunyakaza kwe-piston, kunciphise ukumelana ne-piston, futhi kuvimbela i-piston ukuthi ingqongqoze isilinda. Ngokuvamile, ipiston yenjini yephethiloli isebenzisa izindandatho ezimbili zikagesi kanye nendandatho eyodwa kawoyela, kuyilapho injini yedizili ivame ukusebenzisa amasongo amabili kawoyela nendandatho eyodwa egesi.
Indlela efanele yokufaka yendandatho yePiston imi ngalendlela elandelayo:
1. Okokuqala kudingeka ufake indandatho kawoyela, khona-ke indandatho yegesi, i-oda liphansi-up;
2. Lapho indandatho ngayinye ifakiwe, ukuvulwa kwendandatho yepiston akufanele kunwetshwe kakhulu, ngokwanele ukulingana ne-piston;
3. Faka indandatho kawoyela ehlangene:
Faka indandatho ye-liner ku-piston oil ring groove, unake ukuvulwa kwendandatho ye-liner akukwazi ukugqagqana; Faka amapuleti wensimbi aphansi naphezulu ngaphandle kokusebenzisa amathuluzi ukuvula ukuvuleka. Lapho ufaka, okokuqala cwempent okukodwa kwepuleti yensimbi engezansi ku-slot yendandatho, cindezela isithupha sensimbi ngesithupha sakho, bese uthwebula isithupha solunye uhlangothi ku-Ring slot eceleni kwepuleti lensimbi, bese ulayisha ipuleti elingaphezulu lensimbi ngendlela efanayo. Ungafaki amapuleti ensimbi aphezulu nangaphansi ohlangothini olulodwa lwendandatho ye-liner; Ukugwema ukweqa okungenzeka kokuvuleka kwendandatho ye-liner lapho i-piston idonswa kwisilinda, iyaluza ukuvuleka kwepuleti ephezulu nangaphansi nge-liner ring joitions ngama-degree angama-90 kuya kwayi-120. Ngemuva kokufaka, shintshana kahle nendandatho kawoyela ehlangene ngesandla, futhi kufanele kube bushelelezi ngaphandle kokubambeka.
4. Ukufakwa kweRing Ring:
Sebenzisa amathuluzi akhethekile ukufaka izindandatho ezimbili zegesi kanye nendandatho eyodwa kaphethiloli nakho, ungahlehliseli indandatho yegesi yokuqala nendandatho yegesi yesibili; Uma ifakiwe, uhlangothi lumakwe (hyr, hy, CSR, Tlk, ALS, H, R, njll.). Kufanele abhekane (ukuqondiswa ikhanda le-piston); Hlunga ukuvulwa kwe-Ring yegesi ngama-180 degrees, ungavuli ukuvuleka ekuqondisweni kwe-piston pin.

Umsebenzi wePiston Ring:
1. Umphumela wokubopha uphawu
Indandatho yepiston ingagcina uphawu phakathi kwepiston nodonga lwe-cylinder, futhi ukuvuza kulawulwa okungenani, okuthwalwa yindandatho yegesi. Kungavimba isilinda kanye ne-piston noma isilinda kanye nendandatho yepiston ngenxa yokuvuza komoya phakathi kokuluma; Kungavimbela futhi ukwehluleka okubangelwa ukuwohloka kowoyela.
Isinyathelo 2 Yenza ukushisa
Indandatho yePiston ingadlulisela futhi ihlakaze ukushisa okuphezulu okukhiqizwe ngokuhlanganiswa nodonga lwesilinda, futhi kungadlala indima ekupholiseni ipiston.
3. Umsebenzi wokulawula kawoyela
Indandatho ye-piston ingahlenza uwoyela wokuthambisa okunamathiselwe odongeni lwesilinda ukuze ulondoloze ukusetshenziswa okujwayelekile kawoyela, okuthwalwa yindandatho kawoyela.
4. Ukusekela Umphumela
Indandatho yePiston iqhubekela phambili esilinda, futhi indawo yayo yokuslayida ithwalwa ngokuphelele yindandatho yePiston, ivimbela i-piston ekuxhumaneni nesilinda ngqo futhi idlala indima esekelayo.
Kunezinhlobo ezimbili zezindandatho zePiston: Izindandatho zegesi namasongo kawoyela. Indandatho yegesi isetshenziselwa ukuqinisekisa uphawu phakathi kwepiston nesilinda kanye nokusika umoya ocindezelwe egumbini lokuhlanganisa. Indandatho kawoyela isetshenziselwa ukuklebhula uwoyela owengeziwe kwisilinda, esingavimba uwoyela ukuthi aphunyuke esilwitsheni nokuvutha.
