A drip-feed lubricator's regulation is primarily based on what factors?

Size of the container
Size of the wick and number of strands in the wick
Amount of oil in the reservoir
Speed at which the machinery operates

The correct answer is: Size of the wick and number of strands in the wick

The regulation of a drip-feed lubricator is primarily influenced by the size of the wick and the number of strands in the wick. The wick serves as a medium to transport the lubricant from the reservoir to the machinery. A larger wick or more strands increase the surface area, allowing for a greater volume of oil to be absorbed and subsequently delivered to the moving parts. This controlled delivery is crucial for maintaining the appropriate lubrication within the machinery, preventing wear due to friction. The design of the wick is essential because it determines the rate at which oil flows. If the wick is too small or has too few strands, it will not effectively deliver sufficient lubricant, potentially leading to inadequate lubrication and increased wear on the equipment. Thus, understanding the characteristics of the wick is key to ensuring effective lubrication and the longevity of machinery components.
