Where are the suction and discharge valves mounted on a reciprocating compressor?

The correct answer indicates that the discharge valve is positioned on top of the reciprocating compressor, while the suction valve is located below. This configuration is essential for maintaining proper flow dynamics within the compressor. By placing the discharge valve on top, any gases that have been compressed can efficiently exit the system, utilizing gravity to aid the flow and minimizing the potential for backflow or blockage.

Having the suction valve below allows for effective intake of the gas that needs to be compressed. This arrangement ensures that as the piston moves down, it creates a vacuum that draws the gas into the cylinder, optimizing the compressor's cycle and performance.

This alignment of valves supports a design that promotes efficient operation and allows for gravity to assist in the discharge of the compressed gas while facilitating the suction process effectively from the bottom. Understanding this configuration is crucial for recognizing how reciprocating compressors function and identifying best practices in maintenance and troubleshooting.
