    Abstract: PROBLEM TO BE SOLVED: To provide a condition monitoring system for use with a reciprocating device.SOLUTION: The condition monitoring system 12 includes: at least one pressure sensor 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 communicatively coupled to the pressure sensor and the vibration sensor. The protection system is 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.

    Abstract: The present invention relates to a vibration reduction device for a compressor. The present invention includes the compressor connected to piping, a power supply unit supplying power to the compressor; and a control unit which controls the power supplied to the compressor from the power supply unit. The control unit controls the power supply unit to reduce the vibration generated in the compressor due to the excitation force occurring for multiple times with intervals when the compressor starts or stops. The present invention can minimize the vibration generated in the compressor when the compressor starts or stops.
