What signifies abnormal discharge pressure in a screw compressor?

Abnormal discharge pressure in a screw compressor is often indicated by values that deviate significantly from the expected operational range for that particular system. Typically, screw compressors are designed to operate within certain pressure limits that assure efficient and safe functionality.

In this case, 167 PSIG is the value that suggests abnormal discharge pressure. This level is generally recognized as being outside the normal operating range for many screw refrigeration compressors, which usually operate based on specific conditions related to the system's design and the type of refrigerant in use. Exceeding this pressure can lead to issues such as compressor damage, decreased efficiency, and potential safety hazards like ruptures or leaks.

The other pressure values listed likely fall within a range that is either acceptable or expected during normal operational conditions for screw compressors. For example, values such as 154 PSIG, 31 PSIG, and 22 PSIG can be typical for certain operating conditions, depending on factors like the refrigerant type, compressor load, and ambient conditions. Monitoring these values is crucial for maintaining optimal performance and ensuring the longevity of the compressor systems.
