Piston.
I-Piston ukunyakaza okubuyisela emzimbeni wesilinda senjini yemoto. Isakhiwo esiyisisekelo se-piston singahlukaniswa siphezulu, ikhanda nesiketi. Isihloko sePiston yingxenye eyinhloko yegumbi lokuhlanganisa, futhi ukwakheka kwalo kuhlobene nefomu le-comusction elikhethiwe. Izinjini zikaphethiloli kakhulu zisebenzisa i-flat top piston, enosizo lwendawo encane yokutholwa kokushisa. I-Diesel Injini Piston Top Imvamisa inemigodi ehlukahlukene, ukwakheka kwayo, isikhundla nosayizi kumele kube nge-Diesel Injini Yenhlanganisela Yakheka kanye Nezidingo Zokuhlanza.
I-Piston Top yingxenye yegumbi lokuhlanganisa, ngakho-ke ivame ukwenziwa ngezimo ezahlukahlukene, futhi i-Petroline Piston esebenzisa ngaphezulu i-Flat top noma i-concave ephezulu, ukuze i-concave check, futhi inqubo yokuhlanza ilula, futhi inqubo yokukhiqiza ilula. Ama-pistons ekhanda e-Convex asetshenziswa kakhulu ezinjini ezimbili zikaphethiloli. Iziqongo zePiston of Diesel izinjini zivame ukwenziwa ngemigodi ehlukahlukene.
Ikhanda lePiston liyingxenye ngenhla kwesihlalo sePiston PIN, kanti ikhanda le-piston lifakwe ngendandatho yepiston ukuvikela izinga lokushisa eliphakeme kanye nokucindezela okukhulu kwe-crankcase kusuka ekungeneni kwe-crankcase futhi kuvikele uwoyela ukuthi ungene egumbini lokuhlanganisa; Iningi lokushisa elidonswe ngaphezulu kwe-piston libuye lidluliselwe kusilinda ngekhanda lepiston, bese lidlulisela phakathi nendawo epholile.
Ikhanda le-piston licutshungulwa ngemifino eminingana endandatho yokubeka izindandatho ze-piston ezikhuphukayo, kanti inani lamasongo e-piston lincike kwizidingo ze-seal, ezihlobene nengcindezi yenjini. Izinjini zejubane eliphakeme zinezindandatho ezimbalwa ezimbalwa kunezinjini ezinamajubane eliphansi, nezinjini zikaphethiloli zinezindandatho ezimbalwa kunezinjini zedizili. Izinjini ezijwayelekile zikaphethiloli zisebenzisa izindandatho zegesi ezi-2 kanye nendandatho engu-1; Injini yedizili ine-3 amasongo kagesi kanye nendandatho engu-1; Injini yejubane eliphansi le-Diesel isebenzisa izindandatho zegesi ezi-3 ~ 4. Ukuze kuncishiswe ukulahleka kwezingqubuzana, ukuphakama kwengxenye yebhande kufanele kwehliswe ngangokunokwenzeka, futhi inani lamasongo kufanele lincishiswe ngaphansi kwesimo sokuqinisekiswa kokuqiniseka.
Zonke izingxenye zendandatho ye-piston engezansi kwe-groove zibizwa ngokuthi iziketi zikaPiston. Indima yayo ukuqondisa i-piston kusilinda ngokubuyisa ukunyakaza nokumelana nengcindezi eseceleni. Lapho injini isebenza, ngenxa yomphumela wengcindezi yegesi kwisilinda, i-piston izogoba futhi ilimaze. Ngemuva kokuthi i-piston ifudumele, inani lokunwebisa likhulu kunalezo ezinye izindawo ngenxa yensimbi ePiston Pin. Ngaphezu kwalokho, i-piston izokhiqiza i-defforation yokukhishwa ngaphansi kwesenzo sengcindezi eseceleni. Ngenxa yalokhu kuguqulwa okungenhla, ingxenye yesiketi sePiston iba yi-ellipse eqophelweni le-axis ende ye-perpendicular ePiston Pin. Ngaphezu kwalokho, ngenxa yokusatshalaliswa okungalingani kwamazinga okushisa kanye nesisindo eceleni kwe-axis ye-piston, ukwandiswa okushisayo kwesigaba ngasinye kukhulu phezulu nokuncane phansi.
Ukwehluleka okuyinhloko komhlangano wePiston kanye nezimbangela zabo kungokulandelayo:
1. Ukuqothuka kwendawo ephezulu yepiston. I-piston ablation ivela ngaphezulu kwepiston, ngokukhonkotha okuxekethile emacaleni akhanyayo kanye nokuncibilika kwasendaweni ezimweni ezinzima. Isizathu esiyinhloko sokuthi ubudlova besihloko se-piston bubangelwa ukuhlanganiswa okungajwayelekile, ukuze phezulu bamukele ukushisa okukhulu noma bagijime ngaphansi komthwalo omkhulu ngemuva kokuthi indandatho enkulu ibekwe futhi iphuliwe.
2, indawo ephezulu yemifantu yepiston. Ukuqondiswa kokuqhekeka phezulu kwePiston ngokuvamile kuvame ukufana ne-eksisi yomgodi wePin yePin The Piston, okubangelwa ukuqhekeka kokukhathala okubangelwa ukucindezelwa okushisayo. Isizathu: Ukusebenza okugcwele ngokweqile kwenjini kuholela ekuguqukeni ngokweqile kwe-piston, okuholele ekukhathaleni ukuqhekeka kwendawo ephezulu yepistoni;
3, Piston Ring Groove Side Wall Wear. Lapho i-piston iqhubekela phambili, indandatho ye-piston kufanele ibe yi-radial telescopic ngokushintshana kwesilinda, ikakhulukazi izinga lokushisa le-groove lokuqala liphezulu, futhi lithintwa "ukufunwa kwendandatho, ngakho-ke ukufunwa kwendandatho kwenzeka ku-groove yendandatho, okubangela ukugqokwa;
4. Indandatho yepiston yiCoke yanamathela emgqeni wendandatho. I-Piston Ring Coking ingumphumela wokugcoba oxidation deposition noma ukulahleka kwendandatho yenkululeko yokuhamba ethangini, lokhu kwehluleka kuyingozi kakhulu. Izizathu eziphambili: Ukushiswa ngokweqile kwe-Diesel Ukungcola kawoyela ukungcola kungukuthi, ikhwalithi kawoyela yokuthambisa ayimpofu; I-cranksecase veration divaysi yedivayisi isebenza kabi, idala ingcindezi engemihle noma ukuqina komoya kwe-cylinder, okuholela ekuphuthumeni kwamafutha. Ngakho-ke, kuyadingeka ukuqinisekisa ukusetshenziswa kwamafutha afanelekayo ukuvikela injini yedizili ekushiseni ngokweqile.
