The Principle of Silent Generators 1. Rational planning of the intake and exhaust air outlets of the silent generator set. The power part of the diesel generator set is the internal combustion engine, thus, during the operation of the set, satisfactory air flow is required to ensure the engine's complete combustion and dissipate the heat generated during operation. If the exhaust air volume ratio is unbalanced, it will affect the normal operation of the diesel generator set, leading to high water temperature and power not reaching the extra requirements, etc. Long-term operation under high temperatures will affect the lifespan of the set. 2. Selection and use of noise reduction materials for silent diesel generators. Special cotton is used to absorb sound, thereby achieving noise reduction. Another effective method is to combine perforated mesh noise reduction materials with noise-reducing cotton to handle noise. 3. The appearance and structural design of silent diesel generators facilitate observation of the set's operating conditions, allowing for quick manual emergency shutdown. The intake and exhaust air volumes are strictly calculated and the whole-set disassembly method is used, which is convenient for subsequent maintenance work. The rounded corner design is aesthetically pleasing.
