What is the high stage compressor oil pressure in a two-stage package system?

In a two-stage package refrigeration system, the high stage compressor oil pressure is typically designed to maintain optimal lubrication and cooling for the compressor components during operation. A pressure of 45 PSID (pounds per square inch differential) is considered standard because it ensures that the oil circulation is effective at delivering necessary lubrication to various parts, thus preventing wear and potential failure of the compressor.

This level of oil pressure supports the efficient functioning of the compressor, ensuring that the oil can provide adequate sealing between the piston rings and cylinder walls, as well as cooling the compressor to prevent overheating. Operating at the recommended oil pressure level, such as 45 PSID, contributes to the longevity of the compressor and the overall reliability of the refrigeration system.

Other pressure levels, while they may be associated with specific systems or operational adjustments, are generally not the standard target for high stage compression oil pressure in two-stage systems. Maintaining the specified oil pressure as indicated in the operational guidelines is crucial for optimal performance and reliability in industrial refrigeration applications.
