Heat exchanger manufacturer _ Heat exchanger unit It automatically and continuously converts the heat provided by the primary heating network into hot water for domestic use and heating. Heat exchanger unit It consists of a heat exchanger, circulation pump, make-up pump, electrical control cabinet, filter, base, piping, valves, and instruments, and can be equipped with automatic constant-pressure water supply device, water treatment equipment, water tank, pump frequency control, temperature control valve, and remote communication control, thus forming a complete heat exchange station. Heat exchanger unit The organizational structure needs to be considered, and there is also a resonance problem here, which is like the situation of sound wave oscillation, bringing noise, etc.
Heat exchanger manufacturer _ Heat exchanger unit Solutions for noise problems:
1 Sound insulation and noise reduction treatment is needed for the pipelines, pipes, and cable trenches of the equipment.
2、 Heat exchanger unit When external pipelines pass through the sound insulation enclosure, sealing, damping, and vibration damping treatment is required to prevent structural resonance.
3、 Heat exchanger unit The existing sound insulation enclosure only considers sound absorption without sound insulation and damping treatment. After the sound wave passes through the sound absorption surface, the volume is attenuated, but at this time, the filtered sound waves are mainly mid-high frequency, and almost no effect is achieved for low-frequency isolation. After the sound wave passes through the sound absorption layer, it will also excite the vibration of the rigid structure of the sound insulation enclosure, so sound insulation and damping treatment must be done.
4 It is necessary to point out Heat exchanger unit During the initial installation, the foundation platform needs to be treated with damping to constrain vibrations (this is also the main reason for ground vibrations at close range).
5 The air intake and outlet of the existing sound insulation enclosure's ventilation system only has simple louvers, which have almost no isolation effect on the mainly low and mid-frequency Heat exchanger unit external noise. At the same time, it does not meet the heat dissipation requirements of the existing equipment (without a drainage design, it is difficult to ensure sufficient ventilation, and the heat dissipation requirements cannot be met. Therefore, sound insulation and noise reduction treatment should also be applied to the heat dissipation louvers.
