Design and Development of an Oilfree, Hermetic High Pressure Compressor
نویسنده
چکیده
This paper describes the concept and the design features of a new, oilfree, reciprocating high pressure compressor for technical gases. The compressor is unique in concept and design, and introduces various new design elements. A magnetic coupling makes the compressor hermetic and allows inlet pressures of up to 16 bar. A new kind of clearance seal in the high-pressure stages allows reliable oilfree compression up to 310 bar. Due to the mass balanced scotch yoke drive the compressor operates very smooth and almost vibrationless.

متن کاملDesign of Refrigerant Compressor with Hydraulically Coupled,Hermetically Sealed Linear Drive
Substitution of a metallic diaphragm for the power piston of a Stirling engine is shown to be a promising approach to transmitting power for a heat-actuated heat pump through a hermetic seal. Hydraulic fluid under high pressure transfers the power from the diaphragu to the compressor plunger, which is balanced by a counterweight. The discussion is divided into three parts which deal with the in...
