Embodiment Construction

[0117] The exemplary methods and systems described herein overcome the disadvantages of known monitoring systems by providing a condition monitoring system that facilitates monitoring the status of known reciprocating compressors. Furthermore, the condition monitoring system enables the integrity of the bolting of the throw component of the reciprocating compressor to be determined based on the stiffness of the cylinder assembly while the compressor remains in operation. Also, the condition monitoring system can shut down the reciprocating compressor after determining that the condition of the reciprocating compressor is different than a predetermined condition.

[0118] figure 1 is a schematic diagram of an exemplary reciprocating compressor 10 including a condition monitoring system 12 . figure 2 is a cross-sectional view of reciprocating compressor 10 taken along line 2-2. In the exemplary embodiment, reciprocating compressor 10 is coupled in flow communication between g...

Abstract

The present invention relates to a reciprocating compressor and methods for monitoring the operation of the same. A condition monitoring system (12) for use with a reciprocating device is provided. The condition monitoring system includes at least one pressure sensor (116) configured to sense a pressure within the reciprocating device, at least one vibration sensor (132) configured to sense a vibration of the reciprocating device, and a protection system (22) communicatively coupled to the pressure sensor and the vibration sensor, the protection system configured to calculate a stiffness value of the reciprocating device based on the sensed pressure within the reciprocating device and the sensed vibration of the reciprocating device.

Description

technical field [0001] The present invention relates generally to reciprocating compressors, and more particularly to methods and systems for monitoring the operation of reciprocating compressors. Background technique [0002] At least some known reciprocating compressors include a cylinder assembly coupled to the compressor frame and including a piston assembly that moves in a reciprocating motion within the cylinder head. Known piston assemblies compress the gas channeled within the cylinder head before expelling the compressed gas to an output device. [0003] At least some known reciprocating components in known compressors may experience increased loading (eg, asymmetric loading) due to structural fatigue. Over time, the increased loading may cause increased fatigue cycles on the cylinder assembly and / or other components of the reciprocating compressor, and may lead to premature failure of these components. Also, components that are not properly installed may become s...
