Atlas Copco air compressor ZT55-90 HP DISCH SILENCER KIT Function and Structure
Noise reduction principle: Usually, a combination of resistive and reactive noise reduction designs is adopted. The interior includes porous sound-absorbing materials (such as glass fiber, sound-absorbing cotton) and expansion cavity structures, which can effectively absorb and reflect noise of different frequencies, especially the mid-to-high frequency noise generated by high-pressure gas flow.
Structural composition: Generally, it includes the noise reduction housing, inlet and outlet flanges (or threaded interfaces), internal sound-absorbing components and seals. Some models may integrate pressure buffering functions to reduce the impact of air flow pulsation on the downstream pipelines.
Adaptation characteristics
Model matching: Specifically designed for the ZT55-90 series of high-pressure screw air compressors, it is compatible with their exhaust pressure (around 90 bar, specific to the model parameters) and exhaust volume, ensuring stable operation under high-pressure conditions without additional pressure losses.
Material selection: The main body uses high-pressure-resistant and corrosion-resistant metal materials (such as carbon steel or stainless steel), and the internal sound-absorbing materials need to withstand the impact of high-pressure gas flow and a certain temperature (the exhaust temperature is usually ≤ 100℃), to avoid detachment or failure.
Performance parameters (reference)
Noise reduction effect: Generally, it can reduce noise by 15-30 decibels (dB), depending on the installation location and pipeline layout.
Pressure loss: The design strives for low flow resistance, with pressure loss generally ≤ 0.5 bar, ensuring that it does not affect the exhaust efficiency of the compressor.
Interface size: Matches the exhaust port of ZT55-90, mostly flange connections (such as DN40 or DN50 specifications), and must strictly follow the equipment interface standards.
Maintenance and replacement
Regular inspection: It is recommended to inspect once every 8000-12000 hours, mainly checking for any damage to the appearance, good sealing of the interface, and whether the internal sound-absorbing materials have aged or fallen off (professional personnel need to disassemble and inspect).
Replacement cycle: The general service life is 20000-30000 hours. If the noise significantly increases or the exhaust resistance rises, it is necessary to replace the entire set of components in time.
Advantages of original factory parts: The original high-pressure noise reduction components are fully matched with the exhaust system design of ZT55-90, ensuring the balance of noise reduction effect, pressure resistance performance and flow resistance control, avoiding the decline in exhaust effic
