Indlela yokuqhaqha i-valve spring? Ukungaphumeleli okuqhelekileyo kwe-valve
Okokuqala, amagama ambalwa malunga neemoto. Umthombo wevalve uphakathi kwentloko yesilinda kunye nesihlalo sasentwasahlobo ekupheleni kwesikhondo sevalve. Umsebenzi wayo kukuqinisekisa ukuba ivalve inokufakwa ngokusondeleyo kunye nesihlalo sevalve okanye isitulo sesitulo sevalve xa ivalve ivaliwe, kunye nokoyisa amandla angasebenziyo aveliswa ngumatshini wevalve xa kuvulwa ivalve, ukuze izixhobo zokuhambisa zihlale zihleli. zihlengahlengiswe yi-CAM ngaphandle kokwahlulwa omnye komnye. Ngoko indlela yokususa i-valve spring? Wazi kangakanani?
Indlela yokuqhawula i-valve entwasahlobo: i-disassembly.
Ivalve spring sisixhobo esincinci esiqinisekisa ukuba ivalve ihleli ngoko nangoko kwaye ifakwe nkqi, ikhusela ivalve ekuxhumeni xa i-injini ingcangcazela kwaye yonakalise ukusebenza kwayo kokutywinwa.
1. Krwela isiphelo soqhagamshelo oluphothiweyo lwevalve spring compressor kumzimba wesilinda;
2. Cinezela intloko yoxinzelelo lwe-valve spring compressor kwi-valve spring;
3. Bamba isiphatho ngesandla sakho kwaye ucinezele phantsi de isiphatho silingane. Ngeli xesha, ungafaka iqhosha lokuvala umnyango womoya.
Indlela yokususa imithombo yevalvu: Imithombo yevalvu ihlala inengxaki yokusilela.
1. Ngaphantsi kwesenzo sexesha elide lobushushu obuphezulu kunye ne-periodic high-frequency alternating force, i-valve spring kulula ukuyinxiba kunye nokukhubazeka emva kwexesha elithile. Kule meko, i-spring elasticity iya kuba buthathaka kwaye iyancipha, echaphazela ukuvalwa kwe-valve ayiqinanga, amandla enjini yomatshini ayancipha, kwaye kunzima ukuseta xa uqala. Ukuba imoto imisa ekudibaneni kweendlela, ngaba abahlobo baya kucinga ngemeko yokuhamba ngelo xesha?
2. Iringi ye-valve yasentwasahlobo ichatshazelwa ngumgangatho ophantsi, ukuqina okubuthathaka okanye ukuphambuka okanye ukwaphuka kwe-valve spring. Xa i-injini ibambekile, isandi "sokucofa" sinokuvakala ngokucacileyo kwisivalo segumbi levalvu, kwaye ngamanye amaxesha kukho isandi esingxolayo. Kwiimeko ezinzima, ukusebenza ngokukhawuleza kwemoto kuncitshisiwe, kwaye umcimbi wokuqalisa ubunzima kunye nomsebenzi we-cylinders ngamnye awugudi.
3. Xa i-elasticity ye-oil outlet valve spring iyancipha. Kuya kubangela ukuvuza okunzulu kweoyile yoxinzelelo oluphezulu, ilahle uxinzelelo oluseleyo kumbhobho weoyile woxinzelelo oluphezulu, ivalve yeoli ayinakuhlaliswa ngokukhawuleza, unikezelo lweoyile luba lufutshane kwaye lungazinzi, kwaye injini ayikwazi ukusebenza okanye "ukuhamba". Ukongeza, inokwenza ukuba i-injector iqale ukutshiza ibuthathaka, i-oyile elula inqunyulwe, kwaye kukho i-drop phenomenon. Emva koko iya kuchaphazela ukutshisa kwe-injini, ukuvutha komlilo, umsi wokukhupha kunye nolunye ungcoliseko oluyimfuneko lokusingqongileyo.
