Yintoni intwasahlobo yevalvu yemoto
Intwasahlobo yevalvu yemoto yinxalenye ebalulekileyo yenjini, ebekwe phakathi kwentloko yesilinda kunye nesihlalo sentwasahlobo ekupheleni kwesiqu sevalvu. Umsebenzi wayo ophambili kukuqinisekisa ukuba ivalvu ingena ngokuqinileyo kwisihlalo sevalvu xa ivaliwe, ukuthintela ukungcangcazela ekubangeni ukutsiba nokonakalise ukusebenza kokutywina.
Ulwakhiwo kunye nezixhobo
Ihlala yenziwe ngentambo yentsimbi ye-alloy ekumgangatho ophezulu (njengentambo yentsimbi ye-chromium-vanadium ephakathi okanye intambo yentsimbi ye-silicon-chromium), kwaye inyangwa ngobushushu ukuze yomeleze amandla okudinwa. Umphezulu uyagalelwa okanye uxutywe ne-phosphate ukuthintela umhlwa. Iziphelo ezimbini zentwasahlobo kufuneka zigalelwe emhlabeni kwaye zithe nkqo kwi-axis ukuze kuthintelwe ukugoba ngexesha lokusebenza.
Umsebenzi kunye noBaluko
I-Youdaoplaceholder0 Yoyisa amandla angenawo umbane: Yilwa namandla angenawo umbane eenxalenye zothumelo ngexesha lenkqubo yokuvala ivalvu ukuthintela ukwakheka kwezithuba phakathi kweenxalenye ngenxa ye-inertia.
I-Youdaoplaceholder0 I-Anti-vibration kunye ne-runout : Ithintela iivalvu ekutsibeni xa injini ingcangcazela ukuqinisekisa ukuvaleka kunye nokuthintela ukuvuza komoya okanye iivalvu ziwele kwisilinda zize zenze umonakalo.
Ukulungiswa koyilo lwe-Youdaoplaceholder0: Ngokuyintloko isebenzisa isakhiwo se-double-spring (esineendlela ezichaseneyo zokujikeleza kwangaphakathi nangaphandle), nto leyo ephucula amandla okulwa ne-resonance kwaye inciphise ubude. Nokuba i-spring enye yaphuka, isenokugcina eminye imisebenzi.
Imisebenzi yemithombo yevalvu yeemoto ibandakanya ikakhulu ezi zinto zintathu zilandelayo:
Qinisekisa ukuba iivalvu zivala ngexesha kwaye zingena kakuhle
Intwasahlobo yevalvu iqinisekisa ukuba ivalvu inamathela ngokusondeleyo kwisihlalo sevalvu okanye kwiringi yesihlalo sevalvu xa ivaliwe ngenxa yoxinzelelo lwayo, ithintela ivalvu ukuba ingatsibi kwaye yonakalise ukusebenza kokutywinwa ngenxa yokungcangcazela kwenjini.
Yoyisa amandla angasebenziyo
Xa ivalvu ivuliwe, intwasahlobo kufuneka yoyise amandla angenasiphelo ololiwe wevalvu ukuqinisekisa ukuba izinto zothumelo zihlala zilawulwa yi-CAM. Xa iivalvu zivaliwe, kuyimfuneko yoyise amandla angenasiphelo othumelo lwevalvu kunye nezinto zothumelo ukuze kuthintelwe ukwakheka kokuphuma ngenxa ye-inertia.
Nqanda ukurhawuzelelwa
Yamkela uyilo lwe-variable pitch okanye i-double spring (njenge-double spring embindini) ukunciphisa umngcipheko wokuqaqamba phakathi kwe-frequency yokusebenza kunye ne-frequency yendalo, kwaye ithintele ukuqhekeka kwe-spring. Isakhiwo se-double-spring sinokugcina eminye imisebenzi xa enye iphuka, nto leyo ephucula ukuthembeka.
Ukuqhekeka kwentwasahlobo yevalvu kunokubangela ukusebenza okungaqhelekanga kwenjini, okubonakala ngokucacileyo ngolu hlobo:
Ubunzima ekuqaliseni
Intwasahlobo yevalvu ephukileyo inokubangela ukuba iivalvu zingavuli okanye zingavali ngokuqhelekileyo, nto leyo echaphazela ngqo ukuqalisa kwenjini.
Amandla angaqinisekanga
Ukusebenza okungaqhelekanga kweevalvu kunokukhokelela ekunciphiseni ukusebenza kakuhle kokungenisa kunye nokukhupha umbane, okubangela iingxaki ezifana nokukhupha umbane okungazinzanga kunye nokusetyenziswa kwepetroli okwandisiweyo.
Ingxolo iyanda
Ukungqongqoza okungaqhelekanga kweevalvu kunokubangela ingxolo eyongezelelweyo, kwaye kwiimeko ezinzima, kunokuhamba nesandi sokungqubana kwesinyithi.
Ukungcangcazela kunye nengxolo engaqhelekanga
Ukushukuma rhoqo kunokwenzeka ngexesha lokusebenza kwenjini, kwaye iingxolo ezingaqhelekanga zinokuhamba nokujika kwevili lokuqhuba kwezinye iimodeli.
Iingcebiso zolondolozo
Kucetyiswa ukuba kwenziwe ulungiso olukhawulezileyo, kutshintshwe intwasahlobo eyonakeleyo kwaye kuhlolwe izinto ezifanelekileyo (ezifana nee-valve guides, ii-camshaft bearing, njl.njl.). Ukuba ayilungiswanga ngexesha, inokubangela ukuba injini ishushu kakhulu okanye yonakale kakhulu.
Intwasahlobo yevalvu iphakathi kwentloko yesilinda kunye nesihlalo sentwasahlobo ekupheleni kwesiqu sevalvu. Umsebenzi wentwasahlobo yevalvu kukuqinisekisa ukuba ivalvu inokuncamathiselwa ngokusondeleyo kwisihlalo sevalvu okanye kwindandatho yesihlalo sevalvu xa ivalvu ivaliwe, kwaye yoyise amandla angenamsebenzi adalwa yi-valve train xa ivalvu ivuliwe, ukuze izinto zothumelo zihlale zilawulwa yi-CAM kwaye zingahlukani.
Iisprings zevalvu zenziwe ngocingo lwentsimbi olukumgangatho ophezulu kwaye zinyangwa ngobushushu ukuze zomeleze amandla azo okudinwa. Ukuthintela ispring ukuba ingagqwali, umphezulu wespring kufuneka ugqunywe nge-galvanized kwaye ufakwe i-phosphate. Iziphelo ezimbini zespring kufuneka zigayiwe kwaye zithe nkqo kumgca wespring ukuthintela ispring ukuba ingathambeki ngexesha lokusebenza.
Ii-valve springs ikakhulu zii-cylindrical helical springs, njengoko kubonisiwe kuMfanekiso 1. Xa i-frequency yokusebenza ye-valve spring ilingana okanye i-integer multiple ye-frequency yayo yendalo, i-valve spring iya kuvakala, inyuse amathuba okuqhekeka. Ukuthintela ukuvela kwe-resonance, ii-variable-pitch springs zingasetyenziswa. Okwangoku, uninzi lwee-injini zisebenzisa ii-double springs ezifakwe ngaphakathi. Izikhokelo zokujikeleza kwee-inner springs nezangaphandle zichasene, kwaye ukuqina kwe-inner spring kukhulu kunokwe-inner spring. Ii-double springs azithinteli kuphela ukuvakala kwe-resonance kodwa zifinyeza ubude bee-springs. Kwaye xa enye yee-springs iphuka, enye i-spring ingaqhubeka isebenza, ithintela i-valve ukuba ingaweli kwisilinda.
