Kwizicelo zaselwandle, iivalvu zobhedu zithathwa ngokuba ziphezulu kuneevalve zobhedu ngenxa yokuqina kwazo okuxhathisayo kukutya kunye nokuqina kwiindawo ezirhabaxa zamanzi etyuwa.
Izizathu eziphambili zokuba kutheni iiValuvu zeBronzi zingcono kuSetyenziso lwaseLwandle
1. Ukumelana noKutya okuPhezulu
Imekobume yaselwandle idume ngokugruzuka ngenxa yokuvezwa rhoqo kumanzi anetyuwa. Iivalvu zeBronzi zixhathisa kakhulu kwi-corrosion yamanzi anetyuwa, i-oxidation, kunye ne-pitting, ekwandisa kakhulu ubomi bazo. Oku kubangelwa kukuba ubhedu lwenziwe ngobhedu netoti, indibaniselwano ekwaziyo ukumelana nomhlwa.
Iivalvu zobhedu, kwelinye icala, zinezinc, nto leyo ezenza zibe sesichengeni sokwenziwa kwe-dezincification. Le nkqubo yenzeka xa i-zinc ikhutshelwa kwi-alloy, ishiya ngasemva i-porous, i-copper ebuthakathaka enokuthi iphuke ngokulula phantsi koxinzelelo.
2. Ukonyuka kwamandla kunye noKuhlala ixesha elide
Iivalve zeBronze ziyaziwa ngamandla abo omatshini kunye nokuqina, okwenza ukuba zilungele ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu obuphezulu kwiinqanawa. Ukukwazi kwabo ukumelana neemeko ezinzima kuqinisekisa ukuba basebenza ngokuthembekileyo ekuhambeni kwexesha.
Ngokwahlukileyo, iivalve zobhedu zithambile kwaye zithande ukugoba okanye ukuqhekeka phantsi koxinzelelo oluphezulu, okwenza ukuba zingathembeki kangako kwiinkqubo ezibaluleke kakhulu ezifana nokupholisa injini okanye iinkqubo zamanzi e-ballast.
3. I-Dezincification kunye neMfezeko yezinto eziphathekayo
Omnye wemingcipheko emikhulu yokusebenzisa ubhedu kwiindawo ezihlala elwandle kukuchithwa kwe-dezincification, okunokubangela ukusilela kwevalvu kunye nokuvuza. Iivalve ze-bronze azichatshazelwa kulo mbandela, okwenza kube yindlela ekhuselekileyo, ehlala ixesha elide kwiinkqubo ezibalulekileyo.
Iivalvu zobhedu zinokufaneleka kwimigca yamanzi ahlaziyekileyo okanye usetyenziso olungacinezelekanga, kodwa kwimibhobho yamanzi etyuwa okanye kwiinkqubo zokupholisa i-injini, ubhedu lolona khetho lukhethwayo.
4. Ubomi obude kunye nokuSebenza kweendleko
Nangona iivalve zobhedu zinokuba neendleko eziphezulu zangaphambili, ixesha elide lokuphila kwabo kunye neemfuno zokugcinwa okuphantsi zibenza bangabizi kakhulu ekuhambeni kwexesha. Ukutshintshwa okumbalwa kunye nexesha elincitshisiweyo lokugcinwa lifak' isandla kugcino olubalulekileyo lokusebenza.
Iivalvu zobhedu, ngelixa zingabizi kakhulu ekuqaleni, zinokufuna ukutshintshwa rhoqo ngenxa yokubola, okukhokelela kwiindleko eziphezulu ngokuhamba kwexesha.
