1. Gcina ivalve icocekile

Gcina iindawo zangaphandle kunye nezihambayo zevalve zicocekile, kwaye ugcine ingqibelelo yepeyinti yevalve. Umaleko womphezulu wevalve, intambo yetrapezoidal kwisiqu kunye ne-stem nut, indawo etyibilikayo ye-stem nut kunye nesibiyeli kunye negiya yokuhambisa, intshulube kunye namanye amacandelo kulula kakhulu ukuqokelela ukungcola okuninzi njengothuli, amabala e-oyile. kunye neentsalela zezinto, ezibangela ukuguga kunye nokubola kwivalve.

Ngoko ke, ivalve kufuneka ihlale icocekile. Ngokubanzi, uthuli olukwivalvu kufuneka itshayelwe ngebrashi kunye nomoya ocinezelweyo, okanye nokuba icocwe ngebrashi yocingo lobhedu de umphezulu wokusetyenzwa kunye nomphezulu ohambelanayo ubonise ukukhazimla kwesinyithi, kwaye umphezulu wepeyinti ubonisa umbala wokuqala wepeyinti. Isibatha somphunga siya kuhlolwa kanye kanye ngeshifti ngumntu owabelwe ngokukhethekileyo; Vula iplagi esezantsi yevalve yokugungxula kunye netrap yomphunga rhoqo ukuze ucoceke, okanye uyiqhaqhe rhoqo ukuze ucocwe, ukuze uthintele isivalo ekuvingcisweni bubumdaka.

2.Gcina ivalve ithambisa

Ukuthanjiswa kwevalve, intambo yetrapezoidal yevalve, iindawo ezityibilikayo ze-stem nut kunye nesibiyeli, iindawo zokuthungatha indawo yokuthwala, igiya yokuhambisa kunye negiya yeentshulube, kunye namanye amalungu ahambelanayo kufuneka agcinwe ngokuthambisa okugqwesileyo. imigangatho, ukwenzela ukunciphisa ukungqubana kunye nokuthintela ukunxitywa okufanayo. Kumacandelo angenawo uphawu lweoli okanye i-injector, ekulula ukuba yonakaliswe okanye ilahleke ekusebenzeni, isofthiwe yenkqubo ye-lubrication epheleleyo kufuneka ilungiswe ukuze kuqinisekiswe ukuhamba kweoli.

Iindawo zokuthambisa kufuneka zifakwe i-oyile rhoqo ngokwemiqathango ethile. Ivalve evulwa rhoqo enobushushu obuphezulu ifanelekile ukufakwa i-refueling kanye ngeveki ukuya kwinyanga; Sukuvula rhoqo, iqondo lobushushu alikho phezulu kakhulu ixesha lomjikelo wokugcwalisa i-valve linokuba lide. Izithambisi ziquka i-oyile ye-injini, ibhotolo, i-molybdenum disulfide kunye negraphite. I-oyile ye-injini ayifanelekanga kwivalve ephezulu yobushushu; Ibhotolo ayingeni, nayo. Ziyanyibilika ziphele. Ivalve yobushushu obuphezulu ifanelekile ukongeza i-molybdenum disulfide kunye nokusula umgubo wegraphite. Ukuba igrisi kunye nezinye igrisi zisetyenziselwa iindawo zokuthambisa ezivezwe ngaphandle, njengentambo yetrapezoidal kunye namazinyo, kulula kakhulu ukungcoliswa ngothuli. Ukuba i-molybdenum disulfide kunye ne-graphite powder zisetyenziselwa ukuthambisa, akulula ukungcoliswa ngothuli, kwaye umphumo wangempela wokuthambisa ungcono kunebhotela. I-graphite powder ayilula ukuba isetyenziswe ngokukhawuleza, kwaye ingasetyenziswa kunye nexabiso elincinci leoli yomatshini okanye i-paste ehlengahlengisiweyo yamanzi.

I-valve yeplagi ene-oil filling seal kufuneka izaliswe ngeoli ngokwexesha elichaziweyo, ngaphandle koko kulula kakhulu ukugqoka kunye nokuvuza.

Ngaphandle koko, akuvumelekanga ukunkqonkqoza, ukuxhasa izinto ezinzima okanye ukuma kwi-valve ukukhusela i-valve ekubeni ingcolile okanye yonakaliswe. Ngokukodwa iingcango ze-mesh ezingezizo ezentsimbi kunye neevalve zentsimbi, kufuneka zithintelwe.

Gcina ugcino lwezixhobo zombane. Ukugcinwa kwezixhobo zombane akuyi kuba ngaphantsi kanye ngenyanga ngokubanzi. Iziqulatho zokugcinwa zibandakanya: umphezulu uya kucocwa ngaphandle kokuqokelela uthuli, kwaye izixhobo aziyi kungcoliswa yi-steam kunye ne-oil stains; Umphezulu wokutywina kunye nenqaku liya kuqina kwaye liqine. Akukho kuvuza; Iindawo zokuthambisa ziya kuzaliswa ngeoli ngokwemigaqo, kwaye i-valve stem nut iya kuthambisa ngegrisi; Inxalenye yesixhobo sombane iya kuhlala injalo ngaphandle kokusilela kwesigaba, iswitshi yokulawula kunye ne-thermal relay ayiyi kukhubeka, kwaye ulwazi lokubonisa isibane luya kuchaneka.
