Abstract
Methods and systems are provided to adaptively control a hydraulic fluid supply to supply a driving fluid for applying a driving force on a piston in a gas compressor, the driving force being cyclically reversed between a first direction and a second direction to cause the piston to reciprocate in strokes. During a first stroke of the piston, a speed of the piston, a temperature of the driving fluid, and a load pressure applied to the piston is monitored. Reversal of the driving force after the first stroke is controlled based on the speed, load pressure, and temperature.
Claims19
A gas compressor system comprising:
- a driving fluid cylinder having a driving fluid chamber adapted for containing a driving fluid therein, and a driving fluid piston movable within said driving fluid chamber;
- a gas compression cylinder having a gas compression chamber adapted for holding a gas therein and a gas piston movable within said gas compression chamber;
- a buffer chamber located between said driving fluid chamber and said gas compression chamber;
- said buffer chamber adapted to inhibit movement of at least one non-driving fluid component, when gas is located within said gas compression chamber, from said gas compression chamber into said driving fluid chamber;
- wherein during operation, said buffer chamber contains a gas maintained at a pressure that exceeds the pressure at any time within the gas compression chamber.
A gas compressor system comprising:
- a driving fluid cylinder having a driving fluid chamber adapted for containing a driving fluid therein, and a driving fluid piston movable within said driving fluid chamber;
- a gas compression cylinder having a gas compression chamber adapted for holding a gas therein and a gas piston movable within said gas compression chamber;
- a buffer chamber located between said driving fluid chamber and said gas compression chamber;
- said buffer chamber adapted to inhibit movement of at least one non-driving fluid component, when gas is located within said gas compression chamber, from said gas compression chamber into said driving fluid chamber;
- a piston rod interconnecting said driving fluid piston and said gas piston and extending through said buffer chamber;
- a casing assembly located between said buffer chamber and said gas compression chamber;
- a seal device located at least partially within said casing assembly, said seal device operable to inhibit gas from migrating from said gas compression chamber into said buffer chamber;
- and
- wherein said seal device comprises a plurality of sealing rings mounted in said casing assembly and engaging with an outer surface of said piston rod and an inner surface of said casing assembly to provide a gas seal between said casing assembly and said piston rod.
