NOISE AND VIBRATION OF A RECIPROCATING AIR COMPRESSOR

Noise Diagnostic Strategies in a Fractional Horsepower Reciprocating Piston Compressor

Hybrid Experimental And Analytical Approach To Reduce Low Frequency Noise And Vibration Of A Large Reciprocating Compressor

This paper describes the experimental and analytical techniques used to identify and correct the noise and vibration concerns in a new family of reciprocating compressors. Operating sound, vibration and pressure pulsation data were acquired simultaneously on a prototype compressor. Analysis of this data led to two areas of concern. The first concern was identified using Operating Deflection Sha...

Vibration Analysis of an Air Compressor Based on a Hypocycloidal Mechanism: an Experimental Study

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...

Benchmark Performance Analysis of an Ecm-modulated Air-to-air Heat Pump with a Reciprocating Compressor

A benchmark analysis was conducted to predict the maximum steady-state pet$onnance potential of a nearterm moduikting residential-size heat pump. Continuousiy variable-speed, permane nt-magnet electronically commutated motors (ECMs) were assumed to modulate the compressor and the indoor and outdoor fans in conjunction with existing modulating reciprocating compressor technology A modulating hea...

Experimental Analysis of Screw Compressor Noise and Vibration

Very few reports have been presented to date on the noise and vibrational characteristics of oil injected screw compressors. This time. a series of extensive experimental analysis is performed. It includes the measurements and analysis of compressor casing vibrations. rotor shafts vibrations, torsional <rotational) vibrations. suction and discharge gas pulsations. pressure trans~ ient in one th...
