Kupukuta valavu kumaphatikizapo kuyeretsa ndi kuyang'anira, njira yopera ndi kufufuza.

1. Njira Yoyeretsera ndi Kuyang'anira

Kuyeretsa malo osindikizira mu poto yamafuta, pogwiritsa ntchito katswiri woyeretsa, ndikutsuka kuwonongeka kwa kuwunika kosindikiza.Ming'alu yaying'ono yomwe imakhala yovuta kuzindikirika ndi maso amatha kuzindikirika ndi njira yopaka utoto.

Pambuyo poyeretsa, yang'anani malo osindikizira a disc kapena valve valve ndi mpando, fufuzani ndi zofiira ndi pensulo.Yesani Red Red, yang'anani kujambula kwa SEAL pamwamba, kusindikiza pamwamba;kapena ndi pensulo mu diski ndi malo osindikizira mpando pamabwalo ochepa ozungulira, kenaka diski ndi mpando mozungulira mozungulira, fufuzani Pencil Circle Rub, onetsetsani kuti malo osindikizira asindikizidwa bwino.Ngati chisindikizo sichili chabwino, mbale yokhazikika ingagwiritsidwe ntchito kuyesa diski kapena chipata chosindikizira pamwamba ndi kusindikiza thupi, kudziwa malo akupera.

2. Njira Yogaya

Kugaya ndi njira yodula popanda lathe.Kuya kwa maenje kapena mabowo ang'onoang'ono pamutu wa valve kapena mpando nthawi zambiri ndi zosakwana 0.5 mm, zomwe zingathe kukonzedwa ndi njira yopera.Njira yopera imagawidwa kukhala coarse akupera, sing'anga akupera ndi bwino akupera.

Waukali akupera ndi kuthetsa kusindikiza pamwamba zikande, indentation, pitting ndi zina zolakwika, kuti kusindikiza pamwamba kupeza flatness mkulu ndi mlingo wina wa kusalala, kwa kusindikiza pamwamba pa maziko.Kupera mowuma kumagwiritsa ntchito popera mutu kapena chida chopera, pogwiritsa ntchito pepala lokhala ndi abrasive or coarse abrasive phala, tinthu tating'ono 80 #-280 #, tinthu tating'onoting'ono tating'onoting'ono, kudula voliyumu, kugwiritsa ntchito bwino kwambiri, koma mizere yodula kwambiri, kusindikiza pamwamba kumakhala koyipa.Choncho, kugaya movutikira malinga ngati mutu kapena mpando wa valve ukhoza kuchotsedwa bwino.

Kupera kwapakatikati ndikuchotsa kusindikiza pamwamba pa njere zomata, kupititsa patsogolo malo osindikizira a kusalala komanso kusalala.Pogwiritsa ntchito pepala labwino la mchenga kapena phala lopera bwino, kukula kwa tinthu ndi 280 #-W5, kukula kwa tinthu kuli bwino, kuchuluka kwa kudula ndi kochepa, komwe kumathandiza kuchepetsa roughness, nthawi yomweyo m'malo mwa chida chopera chofanana, kugaya. chida chiyenera kukhala choyera.Pambuyo pakupera kwapakati, ndege yolumikizana ndi ma valve iyenera kukhala yowala.Ngati mumagwiritsa ntchito pensulo pamutu wa valve kapena mpando kuti mujambule ochepa, mutu wa valve kapena mpando motsutsana ndi kuzungulira kwa kuwala kwa bwalo, mzere wa pensulo uyenera kuchotsedwa.

Kupera bwino ndi njira yomaliza yopera valavu, makamaka kupititsa patsogolo kusindikiza pamwamba.Akupera bwino angagwiritsidwe ntchito w 5 kapena bwino ndi mafuta, palafini ndi dilution zina, ndi valavu mutu pa mpando valavu akupera, popanda sewero, izi zimathandiza kwambiri kusindikiza pamwamba.Pamene akupera ambiri wotchi malangizo za 60-100, ndiye n'zosiyana malangizo za 40-90, mokoma akupera kwa kanthawi, ayenera kufufuzidwa, kuti opukutidwa chonyezimira, ndi valavu mutu ndi mpando akhoza kuona bwalo la mzere woonda kwambiri. Pamene mtundu ufika wakuda ndi wowala ndi wakuda ndi wowala, perani mofatsa kangapo ndi mafuta a injini kachiwiri, pukutani ndi gauze woyera.Pambuyo akupera, ndiyeno kuthetsa zolakwika zina, ndiko kuti, ayenera anasonkhana posachedwapa, kuti kuwononga akupera wabwino valavu mutu.

Pamanja akupera, kaya akhakula kapena zabwino, nthawi zonse kudzera kukweza, pansi, kasinthasintha, kubwezerana, kugogoda, kubweza ndi zina ntchito pamodzi akupera.Cholinga chake ndi kupewa abrasive njanji kubwereza, kuti lapping chida ndi kusindikiza pamwamba kupeza yunifolomu akupera, kusintha kusalala ndi kusalala kwa kusindikiza pamwamba.

3. Gawo Loyendera

Mu ndondomeko yopera nthawi zonse kudzera mu siteji yoyendera, cholinga chake ndikumvetsa momwe akupera nthawi iliyonse, kuonetsetsa kuti khalidwe lopukuta likukwaniritsa zofunikira zaumisiri.Tikumbukenso kuti valavu osiyana akupera ayenera kugwiritsidwa ntchito kuti agwirizane ndi zosiyanasiyana chisindikizo pamwamba akupera zida kusintha bwino akupera, akupera chitsimikizo khalidwe.

Kupukuta mavavu ndi ntchito yosamala kwambiri, yofunikira kuti muzichita nthawi zonse, kufufuta, kusintha, nthawi zina kugaya bwino kwambiri, koma pambuyo pa kukhazikitsa kapena kutayikira kwa nthunzi, ndi chifukwa chakuti mu kugaya pali malingaliro akupera pang'ono Osagwira. kugwetsa ndodo yowongoka, yokhotakhota, kapena yopukutira pakona ya kukula kwachitika.
