Njira yowumba ndi kufotokozera ntchito ya kulongedza ma valve

1. Mafotokozedwe amtundu wa Graphite Packing

Pali mitundu itatu yotsatirayi ya ma fillers omwe amagwiritsidwa ntchito kwambiri mavavu

Kuyika komwe kumagwiritsidwa ntchito mu polojekitiyi ndi mtundu umodzi wotsegulira mu Chithunzi 1 ndi kulongedza kwa mphete mu Chithunzi 3. Zithunzi zenizeni ndi izi:

Chithunzi 3 Kulongedza mphete

Ntchito zogwiritsira ntchito mapaketi awiri omwe ali pamwambawa ndi ofanana, kusiyana kuli muzochitika zosiyanasiyana zogwiritsira ntchito. Kutsegula kamodzi kokha ndi koyenera kuti m'malo mwa kunyamula panthawi yokonza ma valve tsiku ndi tsiku. Kuyika kumatha kusinthidwa pa intaneti, ndipo kulongedza mphete ndikoyenera kuwongolera valavu. Amagwiritsidwa ntchito disassembly ndi kukonza.

2. Kufotokozera za graphite kulongedza makhalidwe

Malingana ndi zofunikira zaumisiri pakupanga zodzaza, chodzazacho chiyenera kukhala ndi chiwongoladzanja chokhazikika, kotero padzakhala kukhazikika kuchokera mkati kupita kunja pambuyo pa kudzazidwa. Mitundu iwiri yomwe tatchulayi yamtundu umodzi wotsegulira ma graphite fillers ndi zojambulira zolukidwa zomwe njira yake yomangira imakulungidwa ndi ulusi wambiri wa graphite, ndipo kulimba mtima kumatengedwa ndi mpata woluka ndipo palibe chowonekeratu cholakalaka kukulitsa. Kulongedza mphete yamtundu wa graphite ndi paketi yophatikizika yokhala ndi mkati mocheperako. Pambuyo pa kuyima kwa nthawi yayitali, kukhazikika kwamkati kudzawonetsa ming'alu pamwamba pa kulongedza ndikumasula gawo ili la kupsinjika maganizo. Zodzaza zamtunduwu zidzakhalabe zokhazikika ndipo sizisintha pambuyo poti mng'alu wina wapangidwa. Ikakanikizidwanso, mng'aluwo umasowa ndipo kuchuluka kwa rebound kumakwaniritsa zofunikira.

Zotsatirazi ndi zofunikira zaukadaulo za mphete za graphite zosinthika

 3. Za ntchito graphite kulongedza katundu

Kuyika kwa graphite kumagwiritsidwa ntchito mu malo osindikizidwa pakati pa tsinde la valve ndi chithokomiro chonyamula, ndipo kulongedzako kumakhala koponderezedwa panthawi ya ntchito. Kaya ndi mtundu umodzi wotsegulira kulongedza katundu kapena kulongedza mtundu wa mphete kulongedza, palibe kusiyana mu ntchito ya boma lopanikizidwa.

Chotsatirachi ndi chithunzi cha momwe ntchito yonyamula katunduyo ikuyendera (chithunzi cha kuyesa kwa chisindikizo)
