Per analogia \u00e8 come se, avendo due serbatoi di acqua disposti a due livelli differenti, collegati da un tubo, dicessimo: &#8220;il tubo non fa passare l&#8217;acqua&#8221;&#8230; Se il tubo non \u00e8 tappato, l&#8217;acqua deve passare.<\/p>\n<p>Il tappato del tubo corrisponde alla mancata presenza delle condizioni di progetto nello scambiatore.<\/p>\n<p>A questa domanda, solitamente rispondo con una serie di domande:<\/p>\n<ul>\n<li>i due fluidi ci sono?<\/li>\n<li>i due fluidi arrivano alla pressione corretta?<\/li>\n<li>arrivano alla temperatura corretta?<\/li>\n<li>alla portata di progetto?<\/li>\n<\/ul>\n<p>In pratica chiedo al cliente di verificare lo stato dell&#8217;impianto, che tramite un paio di manometri e termometri posti a monte e valle degli ingressi dello scambiatore, si rivela operazione semplicissima.<\/p>\n<p>Fatte queste rapide verifiche, solitamente la soluzione del problema diviene immediata, infatti la maggior parte delle volte alcune delle condizioni di progetto non sono soddisfatte.<\/p>\n<p>L&#8217;unica alternativa che ancora rimane \u00e8:<\/p>\n<p>lo scambiatore \u00e8 pulito o \u00e8 intasato, sporco (vedere <strong><a href=\"http:\/\/www.tempco.it\/prodotti.asp?ID=16\">service ed assistenza scambiatori di calore<\/a><\/strong>), ma anche questo lo si pu\u00f2 rilevare dalla lettura delle pressioni di lavoro ingresso\/uscita.<\/p>\n<p>Una manciata di strumenti e tutto si risolve&#8230;o almeno si \u00e8 in grado di fare una diagnosi corretta, intraprendendo la soluzione in tempi rapidissimi.<\/p>\n<p><a href=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2008\/03\/dscf0715jpg.jpg\" title=\"Scambiatore di calore completo di strumenti\"><img decoding=\"async\" src=\"https:\/\/www.tempco.it\/blog\/wp-content\/uploads\/2008\/03\/dscf0715jpg.thumbnail.jpg\" alt=\"Scambiatore di calore completo di strumenti\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lo scambiatore non rende&#8230;non scambia&#8230; Questa affermazione l&#8217;ho sentita ormai migliaia di volte e tutte le volte mi fa sorridere.
