6 FAQs about [Anti-resonance of screw air compressor]

Why do screw compressors have torsional resonance?

Screw compressors are very common in industry and their torsional vibration behavior is very important. When this issue is neglected in the design it can lead to torsional resonance in the machine during operation. This is especially true if the structural integrity of the machine does not take this into account in the design.

How to reduce pulsation & vibration in a screw compressor?

Industry standards such as API 619 and API 688 provide methods to minimize the risks of vibration, and pulsation simulations are recommended for compressors larger than 1000 HP / 750 kW. Orifice plates, resonators and pulsation filters (bottles) can effectively reduce pulsation and vibration in screw compressor applications.

Do screw compressors cause vibration problems?

Regarding mechanical considerations, small-bore connections and vessel shells are at risk of having vibration issues due to the higher-frequency pulsation associated with screw compressors. To reduce vibration risks, minimize the number of small-bore connections and instrumentation and apply robust, proven designs.

What is a screw compressor used for?

Screw compressors are used in industrial applications requiring large volumes of gas at high compression ratios.

Are screw compressors oil free?

This paper presents torsional vibration analyses of screw compressors, which are designed oil free for mounting on trucks for year round use and tested at Gardner Denver (GD). Measurements at test stands and field test show that the torque peak in the drive shaft can fluctuate and show large values than normal.

What causes pulsation/vibration in a screw compressor?

Specifically, sources of pulsation/vibration in screw compressors include the shape of the discharge port, the screw profile, the internal clearances, the internal volume ratio, over compression, and under compression, etc . Pulsation and noise issues are encountered in practice almost on a daily basis.
