Provocarea
\n<\/b>\u00centr-o carier\u0103, dou\u0103 pompe de epuizment de 110 kW golesc continuu un bazin \u00een care se acumuleaz\u0103 ape pluviale \u0219i de scurgere. La una dintre ele s-a instalat cavita\u021bia \u00eentre dou\u0103 campanii de analiz\u0103 a vibra\u021biilor: pompa continua s\u0103 func\u021bioneze, dar rotorul ei se eroda, iar performan\u021bele hidraulice sc\u0103deau, f\u0103r\u0103 niciun simptom vizibil.<\/p>\n
Abordarea
\n<\/b>Analiza continu\u0103 a semnalelor electrice a eviden\u021biat, pe 16 aprilie, o semn\u0103tur\u0103 de cavita\u021bie \u00een spectrul curentului motorului. O metric\u0103 dedicat\u0103, care urm\u0103re\u0219te energia la frecven\u021be joase, a crescut brusc \u0219i a r\u0103mas anormal de ridicat\u0103. Clientul, alertat imediat, a confirmat la fa\u021ba locului zgomotul unei cavita\u021bii severe.<\/p>\n
Rezultatul
\n<\/b>Cauza a fost g\u0103sit\u0103 repede: alge \u00eenfundau par\u021bial sorbul de aspira\u021bie comun celor dou\u0103 pompe. La o s\u0103pt\u0103m\u00e2n\u0103 dup\u0103 detectare, bazinul a fost cur\u0103\u021bat prin dragare, iar sorbul a fost cur\u0103\u021bat. Metrica \u0219i puterea activ\u0103 au revenit imediat la normal. O simpl\u0103 cur\u0103\u021bare, planificat\u0103 la momentul potrivit, a evitat \u00eenlocuirea unei pompe \u0219i oprirea sitului.<\/p>\n
