I-Piston.
I-piston iwukunyakaza okuphindaphindayo emzimbeni wesilinda wenjini yemoto. Isakhiwo esiyisisekelo se-piston singahlukaniswa sibe phezulu, ikhanda kanye nesiketi. Ingxenye ephezulu ye-piston yingxenye eyinhloko yegumbi lokushisa, futhi ukuma kwayo kuhlobene nesimo segumbi lokushisa elikhethiwe. Izinjini zikaphethiloli zisebenzisa kakhulu i-piston ephezulu eyisicaba, enenzuzo yendawo encane yokumunca ukushisa. Ingxenye ephezulu ye-piston yenjini kadizili ivame ukuba nemigodi ehlukahlukene, ukuma kwayo, indawo kanye nosayizi wayo kumele kube nezidingo zokwakheka kwengxube yenjini kadizili kanye nokushiswa.
Ingaphezulu le-piston liyingxenye yegumbi lokushiswa, ngakho-ke livame ukwenziwa ngezimo ezahlukene, futhi i-piston yenjini kaphethiloli isebenzisa kakhulu ingaphezulu eliyisicaba noma ingaphezulu eligobile, ukuze igumbi lokushiswa libe lincane, indawo yokushabalalisa ukushisa ibe yincane, futhi inqubo yokukhiqiza ilula. Ama-piston ekhanda le-Convex avame ukusetshenziswa ezinjinini zikaphethiloli ezimbili ezinezinhlungu. Amaphezulu e-piston ezinjini zikaphethiloli avame ukwenziwa ngemigodi ehlukahlukene.
Ikhanda le-piston liyingxenye engaphezulu kwesihlalo sephini le-piston, futhi ikhanda le-piston lifakwe indandatho ye-piston ukuvimbela izinga lokushisa eliphezulu kanye negesi enomfutho ophezulu ukuthi ingangeni e-crankcase futhi kuvimbele uwoyela ukuthi ungangeni ekamelweni lokushisa; Ukushisa okuningi okumuncwa ngenhla kwe-piston nakho kudluliselwa ku-cylinder ngekhanda le-piston, bese kudluliselwa nge-cooling medium.
Ikhanda le-piston licutshungulwa ngemigoqo eminingana yendandatho yokufaka amasongo e-piston, futhi inani lamasongo e-piston lincike ezidingweni zesivalo, esihlobene nesivinini senjini kanye nomfutho wesilinda. Izinjini ezinejubane eliphezulu zinezindandatho ezimbalwa kunezinjini ezinejubane eliphansi, kanti izinjini zikaphethiloli zinezindandatho ezimbalwa kunezinjini zedizili. Izinjini zikaphethiloli ezijwayelekile zisebenzisa amasongo egesi ama-2 kanye nendandatho kawoyela eyodwa; Injini kaphethiloli inezindandatho zegesi ezi-3 kanye nendandatho kawoyela eyodwa; Injini kaphethiloli enejubane eliphansi isebenzisa izindandatho zegesi ezi-3 ~ 4. Ukuze kuncishiswe ukulahleka kokungqubuzana, ukuphakama kwengxenye yebhande kufanele kuncishiswe ngangokunokwenzeka, futhi inani lamasongo kufanele lincishiswe ngaphansi kwesimo sokuqinisekisa ukuvalwa.
Zonke izingxenye zendandatho ye-piston ngaphansi komsele zibizwa ngokuthi iziketi ze-piston. Indima yayo ukuqondisa i-piston esilinda ukuze ihambisane futhi imelane nengcindezi eseceleni. Lapho injini isebenza, ngenxa yomphumela wengcindezi yegesi esilinda, i-piston izogoba futhi iguquke. Ngemva kokuba i-piston isishisiwe, inani lokukhulisa likhulu kunelezinye izindawo ngenxa yensimbi ephinini le-piston. Ngaphezu kwalokho, i-piston izokhiqiza ukuguqulwa kwe-extrusion ngaphansi kwesenzo sengcindezi eseceleni. Ngenxa yokuguqulwa okungenhla, ingxenye yesiketi se-piston iba yi-ellipse ohlangothini lwe-axis ende eqondile nephinini le-piston. Ngaphezu kwalokho, ngenxa yokusatshalaliswa okungalingani kwezinga lokushisa kanye nobunzima eceleni kwe-axis ye-piston, ukwanda kokushisa kwengxenye ngayinye kukhulu phezulu futhi kuncane phansi.
Ukwehluleka okuyinhloko kokuhlanganiswa kwe-piston kanye nezimbangela zako yilezi ezilandelayo:
1. Ukususwa kwengxenye engaphezulu yepiston. Ukususwa kwepiston kuvela phezulu kwepiston, kube nezimbobo ezikhululekile ezimweni ezilula kanye nokuncibilika kwendawo ezimweni ezinzima. Isizathu esiyinhloko sokususwa kwengxenye ephezulu yepiston sibangelwa ukusha okungavamile, okwenza ingxenye ephezulu yamukele ukushisa okukhulu noma igijime ngaphansi komthwalo omkhulu ngemva kokuba indandatho yepiston inamathele futhi iphukile.
2, ubuso obungaphezulu be-piston buqhekeka. Indlela yokuqhekeka ebusweni obuphezulu be-piston ngokuvamile iqonde ngqo ku-axis yembobo yephini ye-piston, okubangelwa kakhulu ukuqhekeka kokukhathala okubangelwa ukucindezeleka kokushisa. Isizathu: ukusebenza ngokweqile kwenjini kuholela ekuguqukeni ngokweqile kwe-piston, okuholela ekuqhekekeni kokukhathala kobuso obuphezulu be-piston;
3, ukuguguleka kodonga oluseceleni kwe-piston ring groove. Lapho i-piston inyuka futhi yehla, i-piston ring kufanele ibe yi-radial telescopic ngokuguquguquka kwesilinda, ikakhulukazi izinga lokushisa le-ring groove yokuqala liphezulu, futhi lithintwa "umthelela" wegesi kanye ne-oyela wedge, ngakho-ke ukungqubuzana kwendandatho nokudlidliza kwenzeka emseleni wendandatho, okubangela ukuguguleka;
4. Indandatho yepiston inamathele emseleni wendandatho. Ukubhoboza kwendandatho yepiston kuwumphumela wokufakwa kwe-oxidation kawoyela okugcobayo noma ukulahlekelwa yindandatho kwenkululeko yokuhamba ethangini, lokhu kwehluleka kuyingozi kakhulu. Izizathu eziyinhloko: ukushisa ngokweqile kwenjini yedizili noma umsebenzi wokulayisha ngokweqile isikhathi eside, okwenza i-gum kawoyela okugcobayo, indandatho yepiston, isilinda siguquke kakhulu ekushiseni; Ukungcola kukawoyela okugcobayo kubi kakhulu, ikhwalithi kawoyela okugcobayo ayimbi; Idivayisi yokungenisa umoya ye-crankcase isebenza kabi, okubangela ukucindezeleka okubi ngokweqile noma ukuqina komoya okubi kwesilinda, okuholela ekugijimeni kukawoyela. Ngakho-ke, kubalulekile ukuqinisekisa ukusetshenziswa kukawoyela ofanelekayo ukuvimbela injini kawoyela ekushiseni ngokweqile.
