Abstract

L'invenzione concerne un procedimento per la ricerca e la localizzazione di perdite nel circuito di raffreddamento dei motori termici, procedimento che consente di realizzare l'operazione in tempi brevi, con costi ridotti e grande affidabilità. Secondo il procedimento, si inietta dell'aria sotto pressione nel circuito chiuso completamente, e si cosparge la superficie esterna di tale circuito con dell'acqua saponata in modo che le perdite vengano rilevate da bolle di sapone presentantisi su tale superficie.The invention relates to a process for finding and locating leaks in the cooling circuit of heat engines, a process which allows the operation to be carried out quickly, with reduced costs and great reliability. According to the method, air under pressure is injected into the closed circuit completely, and the external surface of this circuit is sprinkled with soapy water so that the leaks are detected by soap bubbles present on this surface.
