Abstract
Systems, methods, and non-transitory media for monitoring a reciprocating compressor determining a valve opening of a valve disposed in the reciprocating compressor using a sensor and determining a first location of a piston of the reciprocating compressor at the valve opening. The monitoring also includes determining a valve closing of the valve using the sensor and determining a second location of the piston at the valve closing. Furthermore, the monitoring includes estimating a volumetric efficiency based at least in part on the first and second location.
Claims20
A method for monitoring reciprocating compressor operation, comprising:
- determining a valve opening of a valve disposed in the reciprocating compressor using a sensor;
- determining a first location of a piston of the reciprocating compressor at the valve opening;
- determining a valve closing of the valve using the sensor;
- determining a second location of the piston at the valve closing;
- and
- estimating a volumetric efficiency based at least in part on the first and second location.
A system, comprising:
- a reciprocating compressor having a piston and a valve;
- and
- a controller configured to monitor valve closures of the valve, wherein the controller comprises a processor configured to:
- receive an indication of the valve opening from a sensor coupled to the reciprocating compressor;
- determine a first location of the piston at the valve opening;
- receive an indication of the valve closing from the sensor;
- determine a second location of the piston at the valve closing;
- and
- estimate a volumetric efficiency based at least in part on the first and second location.
A non-transitory computer-readable medium comprising executable instructions that, when executed, cause a processor to:
- receive an indication of a valve opening of a valve of a reciprocating compressor from a sensor coupled to the reciprocating compressor;
- determine a first location of a piston of the reciprocating compressor at the valve opening;
- receive an indication of the valve closing from the sensor;
- determine a second location of the piston at the valve closing;
- and
- estimate a volumetric efficiency for the reciprocating compressor based at least in part on the first and second location.
