AI Technical Summary

Technical Problem

Existing compressors suffer from insufficient cooling efficiency, leading to increased gas heating and reduced efficiency and service life due to thermal expansion and wear of compressor parts.

Method used

A piston compressor with a hydraulic drive incorporating both external and internal cooling systems, where external cooling circuits surround the pneumatic cylinders and internal cooling circuits are located inside them, using hydraulic fluid to remove heat effectively.

Benefits of technology

The combined cooling system reduces gas and cylinder temperatures, minimizing thermal expansion and wear, enhancing thermodynamic efficiency, mass flow rate, and overall compressor performance.

Abstract

The utility model relates to mechanical engineering, specifically compressor technology, and can be used in the chemical, oil and gas, and other industries. Specifically, a piston compressor with a hydraulic drive is proposed, which comprises a drive pump connected via a hydraulic distributor to the hydraulic drive, within which is located a piston with a double-ended rod connected to pistons, one of which is located in the pneumatic cylinder of the first-stage compression unit, and the other in the pneumatic cylinder of the second-stage compression unit. Each of the pneumatic cylinders is equipped with a cooling system consisting of an external cooling circuit, designed as a cavity encompassing the outer region of the pneumatic cylinder, and the cooling system is equipped with an internal cooling circuit, designed as a cylindrical cavity with an internal cup located within the pneumatic cylinder.The technical result is an increase in the productivity and reliability of the compressor by ensuring effective cooling of the compressor pneumatic cylinder. 1 ill.
