Impeta ya piston.
Impeta ya Piston (Piston Ring) ikoreshwa mu gushyira umuyoboro wa piston imbere mu mpeta y'icyuma, impeta ya piston igabanyijemo ubwoko bubiri: impeta yo gukanda n'impeta y'amavuta. Impeta yo gukanda ishobora gukoreshwa mu gufunga umwuka uvanze mu cyumba cyo gutwika; Impeta y'amavuta ikoreshwa mu gukurura amavuta arenze kuri silinda. Impeta ya piston ni ubwoko bw'impeta y'icyuma ifite ubugari bunini bwo kwaguka inyuma, iteranyirizwa mu mwirondoro n'umuyoboro wayo ujyanye. Impeta za piston zisubiranamo kandi zizunguruka zishingira ku itandukaniro ry'umuvuduko wa gaze cyangwa amazi kugira ngo zikore agapfundikizo hagati y'uruziga rw'inyuma rw'impeta na silinda n'uruhande rumwe rw'impeta n'umuyoboro w'impeta.
Imirimo yo gufunga icyuma cya piston irimo gufunga, kugenzura amavuta (kugenzura amavuta), kuyobora ubushyuhe (kohereza ubushyuhe), kuyobora (gushyigikira) inshingano enye. Gufunga: bivuga gufunga gazi, ntureke ngo gazi yo mu cyumba cyo gutwika ijye mu gikapu, gusohora gazi bigenzurwa byibuze, binoze imikorere myiza y'ubushyuhe. Gusohoka k'umwuka ntibizagabanya gusa imbaraga za moteri, ahubwo bizanatuma amavuta yangirika, ari na yo nshingano nyamukuru y'icyuma cya gaze; Guhindura amavuta (kugenzura amavuta): amavuta menshi yo gusiga ku rukuta rwa silinda arakurwaho, kandi urukuta rwa silinda rutwikiriwe n'agapira gato k'amavuta kugira ngo silinda na piston n'impeta bikomeze gushonga, ari na yo nshingano nyamukuru y'icyuma cya peteroli. Muri moteri zigezweho zihuta cyane, hitabwa cyane ku ruhare rwa filime y'amavuta yo kugenzura icyuma cya piston; Gutwara ubushyuhe: ubushyuhe bwa piston bwoherezwa mu gice cya silinda binyuze mu mpeta ya piston, ni ukuvuga ingaruka zo gukonjesha. Dukurikije amakuru yizewe, 70 ~ 80% by'ubushyuhe bwakirwa n'agace ka piston kadakonjeshejwe gakwirakwizwa binyuze mu mpeta ya piston kugera ku rukuta rwa silindiri, naho 30 ~ 40% bya piston ikonjeshwa bigakwirakwizwa binyuze mu mpeta ya piston kugera ku rukuta rwa silindiri; Inkunga: Impeta ya piston igumana piston muri silindiri, ikarinda ko piston ihura neza n'urukuta rwa silindiri, ikarinda ko piston igenda neza, ikagabanya ubukana bwo gukururana, kandi ikabuza piston kugwa kuri silindiri. Muri rusange, piston ya moteri ya lisansi ikoresha impeta ebyiri za gazi n'impeta imwe ya peteroli, mu gihe moteri ya mazutu ikoresha impeta ebyiri za peteroli n'impeta imwe ya gazi.
Uburyo bwiza bwo gushyiraho impeta ya piston ni ubu bukurikira:
1. Banza ushyireho impeta y'amavuta, hanyuma ushyireho impeta ya gazi, urutonde ruri hasi ugana hejuru;
2. Iyo buri mpeta ishyizwemo, umwanya w'impeta ya piston ntugomba kwaguka cyane, uhagije gusa kugira ngo ugere muri piston;
3. Shyiramo impeta y'amavuta ivanze:
Shyiramo impeta y'icyuma mu mwobo w'impeta y'amavuta ya piston, witondere ko umwobo w'impeta y'icyuma udashobora guhurirana; Shyiramo ibyuma byo hasi n'ibyo hejuru udakoresheje ibikoresho byo gufungura imyenge. Mu gihe ushyiraho, banza uhambire impera imwe y'icyuma cyo hasi mu mwanya w'impeta, kanda aho imyenge y'icyuma ifunguye ukoresheje igikumwe cyawe, shyira igikumwe cy'ikindi kiganza mu mwanya w'impeta ku ruhande rw'icyuma, hanyuma ushyiremo icyuma cyo hejuru muri ubwo buryo. Ntugashyiremo ibyuma byo hejuru n'ibyo hasi ku ruhande rumwe rw'impeta y'icyuma; Kugira ngo wirinde ko imyenge y'impeta y'icyuma ishobora guhurirana iyo piston ishyizwe muri silindiri, zunguza imyenge y'icyuma yo hejuru n'iyo hasi ukoresheje impande z'impeta y'icyuma kuri dogere 90 kugeza 120. Nyuma yo gushyiraho, zunguza buhoro impeta y'amavuta ivanze n'intoki, kandi igomba kuba yoroshye idafatana.
4. Gushyiraho impeta ya gazi:
Koresha ibikoresho byihariye kugira ngo ushyireho impeta ebyiri za gazi n'impeta imwe ya gazi, ntuhindure inyuma impeta ya mbere ya gazi n'impeta ya kabiri ya gazi; Iyo ushyizeho, uruhande rugaragaraho (HYR, HY, CSR, TLK, ALS, H, R, nibindi). Igomba kureba hejuru (icyerekezo cy'umutwe wa piston); Tegereza icyuho cy'impeta ya gazi kuri dogere 180, ntuhindukize icyuho werekeza ku cyerekezo cy'agapira ka piston.
5. Mbere yo guteranya impeta ya piston muri silindiri, ni ngombwa guhindura aho buri mpeta ya piston ifunguye.
Imikorere y'impeta ya piston:
1. Ingaruka zo gufunga
Impeta ya piston ishobora gukomeza gufunga hagati ya piston n'urukuta rwa silinda, kandi amazi asohoka agenzurwa byibuze, atwarwa n'impeta ya gaze. Ishobora gukumira silinda na piston cyangwa silinda na piston bitewe n'umwuka usohoka hagati y'urumo; Ishobora kandi gukumira kwangirika guterwa no kwangirika kw'amavuta yo kwisiga.
Intambwe ya 2: Gukoresha ubushyuhe
Impeta ya piston ishobora kohereza no gukwirakwiza ubushyuhe bwinshi buterwa no gushya ku rukuta rwa silinda, kandi ishobora kugira uruhare mu gukonjesha piston.
3. Imikorere yo kugenzura amavuta
Impeta ya piston ishobora gukurura amavuta yo kwisiga afatanye n'urukuta rwa silindiri kugira ngo amavuta akomeze gukoreshwa nk'uko bisanzwe, atwarwa n'impeta y'amavuta.
4. Ingaruka zo gushyigikira
Impeta ya piston izamuka ikanamanuka muri silinda, kandi ubuso bwayo bunyerera butwarwa n'impeta ya piston, bikabuza piston gukorana na silinda mu buryo butaziguye kandi bigatera inkunga.
Hari ubwoko bubiri bw'impeta za piston: impeta za gaze n'impeta za peteroli. Impeta ya gaze ikoreshwa mu kwemeza ko piston na silindiri bifunga neza kandi bigafunga umwuka ufunze mu cyumba gishyushya. Impeta ya peteroli ikoreshwa mu gukuraho amavuta arenze kuri silindiri, ibi bikaba bishobora kubuza amavuta kwinjira muri silindiri no gushya.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
