56.20 €La corrosione galvanica si verifica quando due metalli diversi sono immersi in un elettrolita (come l'acqua salata) e si crea una differenza di potenziale elettrico. Questo può portare alla corrosione accelerata del metallo meno nobile, danneggiando gravemente il motore, gli scambiatori di calore e altri componenti vitali. La corrosione può portare a guasti improvvisi e costose riparazioni.
Un sistema di monitoraggio misura il potenziale elettrico tra il motore e l'acqua circostante. Questo permette di valutare l'efficacia degli anodi sacrificali e di intervenire tempestivamente se il potenziale scende al di sotto dei livelli di sicurezza, indicando che gli anodi si stanno esaurendo.
Il sistema di monitoraggio deve essere installato in un punto facilmente accessibile per la lettura dei valori. Il sensore deve essere immerso in acqua, preferibilmente vicino alla presa a mare o allo scarico del motore, in modo da rilevare il potenziale elettrico reale nell'ambiente in cui opera il motore.
Si consiglia di controllare il sistema di monitoraggio almeno una volta al mese, e più frequentemente (ad esempio, dopo ogni uscita in mare) se si naviga in acque particolarmente aggressive o se si notano anomalie nel funzionamento del motore. Un controllo regolare permette di individuare tempestivamente eventuali problemi e di intervenire prima che causino danni maggiori.
I vantaggi includono la prevenzione di danni costosi al motore, l'aumento della durata dei componenti, la riduzione dei tempi di fermo macchina, la maggiore sicurezza in navigazione e il risparmio sui costi di manutenzione a lungo termine. Un sistema di monitoraggio offre tranquillità e protezione per il tuo investimento.
Se il sistema di monitoraggio indica un potenziale elettrico troppo basso, è necessario sostituire immediatamente gli anodi sacrificali. Prima di farlo, verifica che il sistema di monitoraggio sia correttamente installato e funzionante. Se il problema persiste, consulta un meccanico navale qualificato.
