Tiyimbireni Masiku Ano!

Momwe Mungachitire ndi Valve Kulephera?

Njinga yamoto ikakwera kwa nthawi yayitali, chilolezo chovundikira ma injini chimawonekera, chodabwitsa kwambiri kapena chaching'ono kwambiri, kuti mupeze chifukwa chake, muyenera kufunsa zambiri, wogulitsa valavu yamoto kuti akupatseni mwayi wosavuta.

Kukopa kwa chilolezo chovutikira pa valavu pa injini

Zazikulu kapena zazing'ono mbali injini mavavu njinga yamoto chilolezo chingakhudze magwiridwe antchito a injini. Kutsegulira mochedwa ndi kutsekera koyambirira kwa valavu yolowera: chifukwa chotsegula ma valve osakwanira, kuchuluka kwa mwayi wofotokozedwa ndi osakanikiranawo kumachepetsedwa, zomwe zimapangitsa kuti injini izilephera.

Valavu yayikulu yotulutsa (ndiye kuti nthawi yotsegulira valavu yafupikitsidwa): pakutha, zimatulutsa utsi wochepa, kutsika kwamafuta kokwanira, mchenga wamafuta wochulukirapo, kutentha kwama makina ambiri, kuchepa kwamagetsi, ndi kugogoda kwa valavu, komwe kumakhudza moyo wautumiki wa ziwalo.

Kutsegula koyambirira ndi kutsekedwa mochedwa kwa njinga yamoto yovundikira valavu(nthawi yotsegulira valavu ndiyotalikirapo): imayambitsa kutseka kwa valavu ndi kutayikira kwamlengalenga, komwe kumachepetsa kupanikizika ndi mphamvu ya injini. Zikakhala zovuta kwambiri, valavu ipanga kaboni wambiri kapena chimbudzi, kuti silinda isagwire bwino ntchito.

Valavu yaying'ono yotulutsa: imabweretsa kutsekeka kwa ma valve ndikutulutsa mpweya ku Nanchang, kotero kuyaka sikokwanira ndipo mphamvu imachepa. Nthawi zina pamakhala zotulutsa zotulutsa chitoliro.

Momwe mungachitire ndi kuwonongeka kwa ziwalo zamagalimoto zamagalimoto zamagalimoto

 

1. Pamwamba pa valavu nchosweka kapena chophimbira, chomwe chiyenera kusinthidwa.

2. Tsitsi lakumapeto kwa ndodo ya valavu likatha, limatha kukhala pansi pa chopukusira chakunja ndikugwiritsanso ntchito mawonekedwe osalala atabwezeretsedwanso.

3. Mlingo wopindika wa ndodo ya valavu umadutsa 0.03mm. Zokhotakhota zomwe zili pamwamba pa valavu zikadutsa 0.02mm, bulge imatha kukonzedwa poiyika pamakina osindikizira kenako ndikuyang'aniridwa ndi cholozera chazitsulo choboola V mpaka itakwanira.

4. Ngati pali mpweya wakuda wakuda ndi imvi pa lead cone pamwamba, imatha kuviika palafini, kenako nkuchotsa ndi chopukutira chamatabwa kapena burashi yamkuwa ikatha.

5. Ngati ndodo ya valve siinavale kwambiri ndipo kupatuka kozungulira ndi kuzungulika sikunapitirire 0.03mm, ndodo ya valavu imatha kupukutidwa mpaka kukula kwake pakakonzedwe kopanda makina, kenako kukonzedwa ndi njira ya chrome.

6. Kukhomerera pang'ono, maenje, ndi zina zambiri pamtunda wamagetsi nthawi zambiri zimachotsedwa ndikupera dzanja. Musanagaye, valavu, mpando wa valavu, ndikuwongolera mafuta oyela, kenako pachitsulo cha valavu chophimbidwa ndi phala losalala, ndikupindika kwa mphira kuti mutenge pamwamba pa valavu kuti izungulire mobwerezabwereza ndikusintha malo, maenje, maenje, ndi zina akupera kunja.

Mphete yoyera ikawoneka pamagudumu a valavu, valavu imakonzedwa ndi phala labwino. Pomaliza, tsukani phala ndi mafuta, kuthira mafuta, ndikupera kwa mphindi zochepa.

7. Maenje akuya, maenje, ndi mawanga pamalo opindika bwino a valavu ayenera kupukutidwa pamakina opangira ma valve. Ngati zida zomwe zili pamwambazi sizikupezeka, valavu imathanso kumangirira ndipo kusunthika kumatha kuwerengedwa ndi collet yapa benchi, lathe yaying'ono, kapena kubowola kwamagetsi. Kenako valavu imatha kuyambika. Zolakwazo zitha kusungidwa m'mbali mwa cholumikizacho ndi fayilo yabwino, ndipo mawonekedwe ake amatha kupukutidwa ndi nsalu ya 00 emery pa fayilo. Liwiro umapezeka sayenera kwambiri, kayendedwe ayenera kukhala yosalala. Ngati m'mphepete mwa valavu amapezeka kuti ndi wochepera 0.5mm kapena wopindika, uyenera kusinthidwa.

Kodi mungathane bwanji ndi kuwonongeka kwa zida zamagalimoto zamagalimoto zamoto?

(1) Ikani mafuta ofiyira osanjikiza kapena mafuta ojambulira pamalo opindika bwino, kenako ndikanikizire valavu pampando wa valavu ndikusinthasintha kwa gawo limodzi musanatuluke. Ngati pali mphete ya mafuta ofiira mosalekeza kapena mafuta pamakina pampando wa valavu zikutanthauza kuti kusindikiza kuli bwino.

(2) Ndi pensulo yofewa (4B kapena 5B) jambulani mizere ingapo pachipilala cha valavu, kenako kambiranani ndi mpando wa valavu mutembenuzire gawo la 1/4 mukatulutsa, monga mizere ya pensulo pachitsulo cha valavu yadulidwa kuchoka, kumawonetsanso chisindikizo chabwino.

Ngati mukufuna kudziwa zambiri za injini yabwino yamagetsi, chonde musazengereze kutifunsa.
