Rated discharge volume: This is the discharge volume indicated on the compressor’s nameplate, representing the volume of gas discharged by the compressor under specific inlet conditions. The common units are m3/min and m3/h. Rated exhaust pressure: This is the exhaust pressure indicated on the compressor’s nameplate, and the common units used are MPa and bar. 2. Exhaust temperature: For the sake of carbon buildup and safe operation, for media with a relative molecular weight of 12 or less, the exhaust temperature shall not exceed 135℃ ； The exhaust temperature for acetylene, propane, and wet chlorine shall not exceed 100℃ ； For other gases, it is recommended not to exceed 150°C. 3. Piston force: The gas force acting on the piston is greatest at the dead center, and therefore this gas force is referred to as the piston force. 4. Number of stages: For large and medium-sized reciprocating compressors, the number of stages is determined based on the principle of minimizing work consumption; typically, the pressure ratio per stage is ≤4.
