Yintoni i-piston yemoto
I-piston yemoto yinxalenye ephambili ehambayo kwinjini yokutsha yangaphakathi eguqula amandla obushushu abe ngamandla oomatshini . Idlulisela uxinzelelo lokutsha kwi-crankshaft ngentshukumo ephindaphindayo kwaye ithatha inxaxheba ekwakhiweni kwegumbi lokutsha.
I-Youdaoplaceholder0 Iinkcazo kunye nemisebenzi ephambili
I-piston yemoto yinxalenye yesilinda efakwe ngaphakathi kwesilinda yenjini. Imisebenzi yayo ephambili ibandakanya:
Ukuguqulwa kwamandla e-Youdaoplaceholder0: Uxinzelelo lwegesi oluveliswa kukutsha kwepetroli ludluliselwa kwi-crankshaft ngephini yepiston kunye nentonga yokudibanisa, luyiguqula ibe ngamandla okujikeleza.
I-Youdaoplaceholder0 Ulwakhiwo lwegumbi lokutsha : Kunye nentloko yesilinda kunye nodonga lwesilinda, yenza indawo yokutsha evaliweyo.
Ulungelelwaniso lwentshukumo ye-Youdaoplaceholder0: Umjikelo we-four-stroke wokungenisa, ukucinezela, ukuvelisa umbane kunye nokuphuma komoya ugqitywa ngokulungelelanisa intshukumo ejikelezayo.
I-Youdaoplaceholder0 Izakhiwo kunye neempawu zezinto
I-piston isebenzisa uyilo oluhlukeneyo:
I-Youdaoplaceholder0 top: Zithwala ngokuthe ngqo uxinzelelo lokutsha, iinjini zepetroli zihlala zinesakhiwo esithe tyaba phezulu, ngelixa iinjini zedizili zihlala ziyilelwe ngemingxuma ukuhlangabezana neemfuno zokutsha.
Intloko ye-Youdaoplaceholder0 : Inxalenye ebalulekileyo yokufaka iiringi zepiston, ezinee-grooves ezi-3 ukuya kwezi-4 (iiringi zegesi kunye neeringi zeoyile) ukuze kufezekiswe ukuvalwa kunye nokuthambisa.
Isiketi seYoudaoplaceholder0 : Umsebenzi okhokelayo, ukugquma komphezulu kunciphisa ukungqubana, uyilo lwanamhlanje ludla ngokuba "lufutshane kwaye lutyebile" ukuphucula ukuqina kunye nokuchithwa kobushushu.
Izinto eziphambili yi-aluminium alloy, edibanisa ukukhanya okulula (ukunciphisa amandla angenawo amandla) kunye nokumelana nobushushu obuphezulu. Ezinye iimodeli ezisebenza kakhulu zisebenzisa i-nickel plating okanye i-ceramic coating
I-Youdaoplaceholder0 Indawo yokusebenza kunye nemingeni yobugcisa
Iipiston zisebenza phantsi kweemeko ezinzima kakhulu:
I-Youdaoplaceholder0 Ubushushu obuphezulu kunye noxinzelelo oluphezulu : Ubushushu obukhawulezileyo begumbi lokutsha budlula i-2500K, kwaye umphezulu uhlala uthwala uxinzelelo lwe-3-9MPa.
Intshukumo yesantya esiphezulu se-Youdaoplaceholder0: Injini yepetroli inokufikelela kwisantya sokujikeleza se-6000rpm, esihambelana nesantya esithe tyaba esidlula i-20m/s.
I-Youdaoplaceholder0 Amandla antsonkothileyo : iphantsi kwemithwalo yempembelelo rhoqo, uxinzelelo olusecaleni kunye nokuguquguquka koxinzelelo lobushushu.
Iipiston zanamhlanje ziphucula ulwakhiwo lwazo ngohlalutyo lwezinto ezilinganiselweyo kwaye zamkela izinto ezintsha zobuchwepheshe ezifana nemijelo yeoyile yokupholisa kunye neengubo zokuthintela ubushushu ukujongana nale mingeni.
I-piston iyonke inokwahlulwahlulwa ibe ziinxalenye ezintathu: umphezulu we-piston, intloko ye-piston kunye nesiketi se-piston.
Umsebenzi ophambili wepiston kukuthwala uxinzelelo lokutsha kwi-cylinder nokudlulisela la mandla kwi-crankshaft ngephini yepiston kunye nentonga yokudibanisa. Ukongeza, i-piston, kunye nentloko yesilinda kunye nodonga lwesilinda, zenza igumbi lokutsha.
I-piston top yinxalenye yegumbi lokutsha kwaye idla ngokwenziwa ngeemilo ezahlukeneyo. Kwiinjini zepetroli, i-piston top ikakhulu isebenzisa i-flat top okanye i-concave top ukwenza isakhiwo segumbi lokutsha sibe ncinci, indawo yokusasaza ubushushu ibe ncinci, kwaye inkqubo yokuvelisa ibe lula. Ii-convex top pistons zihlala zisetyenziswa kwiinjini zepetroli ezine-stroke ezimbini. I-piston top yenjini yedizili idla ngokwenziwa ibe yimingxunya eyahlukeneyo.
Intloko yepiston yinxalenye engaphezulu kwesihlalo sepiston pin. Iiringi zepiston zifakelwa entlokweni yepiston ukuthintela igesi enobushushu obuphezulu kunye noxinzelelo oluphezulu ukuba ingangeni kwi-crankcase kunye nokuthintela ioyile yenjini ukuba ingangeni kwigumbi lokutsha. Uninzi lobushushu obufunxwa yintloko yepiston budluliselwa kwisilinda ngentloko yepiston kwaye emva koko buthwalwe yi-cooling medium.
Intloko yepiston ifakelwe imingxunya emininzi yeringi yokufaka imingxunya yepiston. Inani leeringi zepiston lixhomekeke kwiimfuno zokuvala kwaye lihambelana nesantya senjini kunye noxinzelelo lwesilinda. Inani leeringi kwinjini ekhawulezayo lingaphantsi kunelo likwinjini ekhawulezayo, kwaye inani leeringi kwinjini yepetroli lingaphantsi kunelo likwinjini yedizili. Injini yepetroli eqhelekileyo isebenzisa imingxunya emibini yegesi kunye neringi enye yeoyile. Injini yedizili ineeringi ezintathu zegesi kunye neringi enye yeoyile. Iinjini zedizili ezikhawulezayo zisebenzisa imingxunya yegesi emi-3 ukuya kwe-4. Ukunciphisa ilahleko zokungqubana, ukuphakama kwenxalenye ye-annular kufuneka kwehliswe kangangoko kunokwenzeka. Phantsi kwemeko yokuqinisekisa ukuvalwa, kufuneka kwenziwe imizamo yokunciphisa inani leeringi.
Zonke iindawo ezingaphantsi kwe-piston ring groove zibizwa ngokuba zii-piston skirts. Umsebenzi wayo kukuqondisa i-piston ukuba yenze intshukumo ephindaphindayo kwi-cylinder kwaye ithwale uxinzelelo olusecaleni. Xa injini isebenza, ngenxa yempembelelo yoxinzelelo lwegesi ngaphakathi kwi-cylinder, i-piston iya kugoba kwaye iguquke. Emva kokuba i-piston ishushu, kuba kukho isinyithi esingaphezulu kwi-piston pin, ukwanda kwayo kukhulu kunoko kwezinye iindawo. Ukongeza, i-piston iya kuphinde iguquke ngokucinezela phantsi kwesenzo soxinzelelo olusecaleni. Iziphumo ezidibeneyo zokuguquguquka okungentla zibangela ukuba i-cross-section ye-piston skirt ibe yi-ellipse ene-long axis ethe nkqo kwicala le-piston pin. Ukongeza, ngenxa yokusasazwa kobushushu nobunzima obungalinganiyo kwi-axis ye-piston, ukwanda kobushushu kwe-cross-section nganye kukhulu phezulu kwaye kuncinci ezantsi.
