What is the main purpose of a lantern stuffing ring in refrigeration systems?

The main purpose of a lantern stuffing ring in refrigeration systems is to lubricate the shaft. This component is typically used in conjunction with a pump to provide a sealing mechanism that prevents leakage of refrigerant while also allowing for the introduction of lubricating oil. The lantern stuffing ring is designed to facilitate a controlled flow of lubricant around the shaft, ensuring that it remains properly lubricated during operation. Adequate lubrication helps reduce friction, wear, and overheating of the shaft, which is critical for maintaining the efficiency and longevity of the equipment in a refrigeration system. Proper functioning of the lantern stuffing ring is essential to preventing leaks and ensuring optimal performance of the system.
