Pantchito zam'madzi, ma valve amkuwa nthawi zambiri amawonedwa kuti ndi apamwamba kuposa ma valve amkuwa chifukwa cha kulimba kwawo kwa dzimbiri komanso kulimba m'malo ovuta, amchere.
Zifukwa zazikulu Zomwe Mavavu a Bronze Amakhala Abwino Kugwiritsa Ntchito Panyanja
1. Kukaniza kwapamwamba kwa Corrosion
Malo a m'nyanja ndi odziŵika bwino chifukwa cha madzi amchere omwe amakhala nthawi zonse. Mavavu amkuwa amalimbana kwambiri ndi dzimbiri lamadzi amchere, oxidation, ndi pitting, zomwe zimatalikitsa moyo wawo. Izi zili choncho chifukwa bronze amapangidwa kuchokera ku mkuwa ndi malata, zomwe mwachibadwa zimapirira ndi dzimbiri.
Koma ma valve amkuwa, amakhala ndi zinc, zomwe zimawapangitsa kukhala osatetezeka ku dezincification. Izi zimachitika pamene zinc imachotsedwa mu alloy, ndikusiya mkuwa wonyezimira, wofooka womwe ukhoza kusweka mosavuta.
2. Kuwonjezeka kwa Mphamvu ndi Kukhalitsa
Ma valve amkuwa amadziwika chifukwa cha mphamvu zamakina komanso kulimba kwawo, zomwe zimawapangitsa kukhala abwino kwambiri pakugwiritsa ntchito kuthamanga kwambiri komanso kutentha kwambiri pazombo. Kukhoza kwawo kupirira mikhalidwe yovuta kumatsimikizira kuti amagwira ntchito modalirika pakapita nthawi.
Mosiyana ndi zimenezi, ma valve amkuwa ndi ofewa komanso amatha kupindika kapena kusweka pansi pa kupanikizika kwakukulu, zomwe zimapangitsa kuti zikhale zodalirika kwambiri pa machitidwe ovuta monga kuzirala kwa injini kapena madzi a ballast.
3. Dezincification ndi Umphumphu wa Zinthu
Chimodzi mwa ziwopsezo zazikulu zogwiritsa ntchito mkuwa m'malo am'madzi ndi dezincification, zomwe zingayambitse kulephera kwa ma valve ndi kutayikira. Mavavu amkuwa samakhudzidwa ndi nkhaniyi, kuwapangitsa kukhala otetezeka, okhazikika osankha machitidwe ofunikira.
Mavavu amkuwa atha kukhala oyenera pamizere yamadzi opanda mchere kapena osapanikizidwa, koma pamapaipi amadzi amchere kapena makina oziziritsira injini, mkuwa ndiye chisankho chomwe chimakonda.
4. Moyo wautali ndi Mtengo Wabwino
Ngakhale mavavu amkuwa amatha kukhala ndi mtengo wapamwamba wakutsogolo, kutalika kwawo kwa moyo wautali komanso zofunikira zocheperako zimawapangitsa kukhala okwera mtengo pakapita nthawi. Zosintha zochepa komanso kuchepetsedwa kwa nthawi yokonza zimathandizira kuti ntchitoyo ikhale yofunika kwambiri.
Mavavu amkuwa, ngakhale otsika mtengo poyambira, angafunike kusinthidwa pafupipafupi chifukwa cha dzimbiri, zomwe zimapangitsa kuti pakhale ndalama zambiri pakapita nthawi.
