What is the primary function of the compressor stuffing box oil lantern?

The primary function of the compressor stuffing box oil lantern is to prevent gas leakage. In a compressor system, the stuffing box serves as a seal to contain the gases within the compressor while allowing the moving parts to operate smoothly. The oil lantern, which is essentially a type of seal that is lubricated by oil, ensures that the interface between the shaft and the stuffing box is properly sealed. This prevents the gas inside the compressor from leaking out into the atmosphere, which is essential for maintaining operational efficiency and safety.

While lubrication, cooling, and efficiency are important factors in compressor operation, they are secondary to the primary role of the stuffing box oil lantern in ensuring a secure seal against gas leakage. Thus, the effectiveness of the lantern in preventing potential leaks is crucial for system integrity and performance.
