Ukuchithwa kweqela le-piston yokudibanisa intonga
Ukuba imoto yakho igxininiswe emanzini, nceda unganyanzeli ukuvutha, kuba xa amanzi engaphezulu kwe-injini yokungenisa umoya, amanzi aya kungena ngokuthe ngqo kwi-cylinder, enze umxube wamanzi athambileyo, igesi inokunyanzeliswa, kunye namanzi. ayinakucinezelwa.Xa i-injini isemanzini kwaye i-crankshaft ityhala intonga yokudibanisa ukuze icinezele kwicala lepiston, amanzi akanakuxinzelelwa.Emva kokuba intonga yokudibanisa ixhomekeke ekuchaseni kwamanzi, iya kuguqula kwaye igobe, okanye iphule.
1. Izilumkiso zokuqhawula
① Uthuli lwangaphandle kufuneka lususwe ngaphambi kokuchithwa, jonga ngokucophelela kwaye ukhumbule indawo kunye nophawu lwenxalenye nganye edibeneyo.
② Ngaphambi kokuba utsale intonga yokudibanisa ipiston, inyathelo lekhabhoni kwindawo ephezulu ye-cylinder liner kufuneka ikhuhlwe ukunqanda ukonakalisa ipiston kunye neringi yepiston.
③ Xa uthatha iqela lepiston yokudibanisa intonga, intonga yokhuni inokutyhalelwa ngaphandle ngokuthe ngqo.Emva kokuba iqela lokudibanisa i-piston likhutshwe, isigqubuthelo sentonga yokudibanisa, i-tile kunye ne-bolt rod bolt kufuneka ifakwe kwi-situ ngokukhawuleza.
④ Xa ususa i-cylinder liner, i-cylinder liner puller okanye intonga yokhuni kufuneka isetyenziswe.Musa ukubetha i-cylinder liner ngokuthe ngqo ngentonga yentsimbi.
⑤ Iringi yepiston esusiweyo kufuneka ibekwe ngokulandelelana.Iigasthi ze-cylinder kunye neegaskets zephepha kufuneka zigcinwe ngokufanelekileyo.
⑥ Ukuba kuyimfuneko ukususa i-flywheel, i-flywheel puller kufuneka isetyenziswe, kwaye iibholithi ezimbini zesitsali kufuneka zijijwe ngokutshintshanayo, kwaye akuvumelekanga ngokungqongqo ukusebenzisa ihamile yesandla ukubethelela kabukhali.Xa ususa i-flywheel, ukwenzela ukukhusela i-flywheel ekhululekile ngokukhawuleza yokulimala, musa ukukhawuleza ukususa i-nut nut emva kokukhulula.
2. Amanyathelo okhuseleko ofakelo
① Amalungu kufuneka acocwe phambi kofakelo, jonga ukucocwa, kwaye wenze uvavanyo lobuchule.Amacandelo angahlangabezani neemfuno zobugcisa kufuneka alungiswe okanye atshintshwe.
② Umngxuma wegumbi le-vortex phezulu kwepiston kunye nomngxuma weoli yokuthambisa kwisiphelo esincinci sentonga yokudibanisa kufuneka ibe kwicala elinye, kwaye kufuneka libe phezulu.
③ Xa utshintsha i-cylinder liner entsha, iseti ye-cylinder kufuneka ifakwe kumngxunya wofakelo ngaphambi kokufaka iringi yokumelana namanzi, jonga ubude bomzimba ojikelezayo, kwaye unokufakwa ngokusemthethweni emva kokuhlangabezana neemfuno.I-cylinder liner ye-injini ye-diesel ye-S195 inokujikelezwa i-90 ° ukuba ukunxiba akukukhulu.I-cylinder liner ye-injini ye-diesel ye-S195 ayinakuguqulwa.
④ Xa ufaka umsesane wepiston, qaphela ukuba ungakrwala ipiston kwaye wophule umsesane wepiston.Iringi ye-chrome-plated iya kufakwa kwi-ring groove yokuqala.Ukuba udini lwangaphakathi lwesangqa sesibini nesesithathu sineengcango, iigrooves kufuneka zenziwe phezulu;Ukuba umphetho wangaphandle unemibhobho, i-grooves kufuneka yenziwe phantsi.I-chamfer kumphetho wangaphandle we-oyile ye-oyile kufuneka ibe phezulu.Amakhonkco egesi amabini kunye nesithathu kwindandatho ye-piston emine ngamakhonkco e-conical, kwaye icala eline "isebe" okanye "┬" kwindandatho kufuneka libe phezulu xa lifakwe.Xa ufaka i-oyile edibeneyo, i-lining ring kufuneka ifakwe kuqala, kwaye iziphelo zayo zombini akufanele zidibanise kwaye zigobe, kwaye emva koko ufake i-ring ring elandelayo, ukuze icinezele i-ringing ring, kwaye emva koko ufake i-waveform ring ngaphezu kwamakhonkco amabini asicaba.Xa usebenzisa imisesane ye-piston ene-ring-ring okanye i-oyile edibeneyo, i-oyile ye-oyile kufuneka ilayishwe kwi-groove yokuqala ye-oyile.I-piston yokudibanisa intonga kufuneka ifakwe ngeoli entsha ebusweni bepiston kunye ne-cylinder liner ngaphambi kokulayisha kwi-cylinder.Xa ulayisha, ukuvulwa kweringi yepiston kufuneka kugxininiswe i-120 ° ukusuka komnye nomnye, kwaye ugweme umgodi wangoku we-eddy kunye nomngxuma wepiston, thintela indawo yepiston phantsi koxinzelelo lwecala.Izixhobo ezikhethekileyo (iintsimbi zentsimbi) kufuneka zisetyenziswe xa i-piston ring ilayishwe kwi-cylinder liner.
Emva kokusetyenziswa, iibheringi eziphambili zekhohlo kunye nekunene azivumelekanga ukuba zitshintshwe, kwaye iileyili zentonga eziphezulu kunye nezantsi azikwazi ukufakwa ngokungalunganga.I-tile yokudibanisa i-tile kufuneka ibe ne-tightness ethile emva kokucinezela kwisihlalo se-tile, kwaye iphezulu kancinane kunesihlalo se-tile.
6. I-roll edge ye-cylinder pad kufuneka ibhekane necala lentloko ye-cylinder, kwaye imingxuma kufuneka ihambelane nemingxuma yomzimba.Xa uqinisa i-nut ye-cylinder head nut, kufuneka iqiniswe ngokulinganayo kumacandelo e-diagonal cross ngokwe-torque echaziweyo.Ukukhululeka kakhulu kulula ukuvuza kunye nokutshisa i-cylinder pad;Ukuqiniswa kakhulu kulula ukwenza i-cylinder pad ilahlekelwe u-elasticity, okukhokelela kwi-bolt okanye i-screw hole slip.Buyisela igasket entsha yesilinda, kwaye uqinise i-cylinder head nut kwakhona emva kwe-20h yokusebenza.
