Description

Technical Field

[0001] The present invention relates to the technical field of ships, in particular to an equipment debugging stethoscope. Background Art

[0002] During the ship mooring test, navigation test or operation stage, when equipment fails, using sound to identify the operating status is a simple, direct and non-destructive method to obtain internal fault information of the machinery. At present, during the general mooring test and commissioning stage, when the equipment is running on site, the noise level of the construction site is very loud, and the acquisition of internal fault sounds by the ears of personnel is still uncontrollable and cannot be clearly obtained, making fault diagnosis more difficult. Generally, the faulty equipment needs to be run repeatedly for more than ten times to obtain the internal sound more completely, but the sound is not retained and can only be heard by maintenance personnel and others. It is impossible to accurately relay it, which is not conducive to the subsequent fault characterization. Ultimately, the fault can only be located and characterized through more labor-intensive methods such as equipment disassembly and inspection.
