B1 introduction to constant level lubrication Constant level oilers are designed to maintain a predetermined oil level in a sump, which is necessary for proper lubrication. If the oil level were to drop below this point, the depleted oil would automatically be replenished by the lubricator, returning it to its original level. With the use of constant level oilers, maintenance efficiencies can be increased, while minimizing maintenance costs, and the loss of production time. Direction of shaft rotation The majority of constant level oilers available are adjustable, allowing for use in many applications. However, there are oilers available Vented constant level oiler with that do not allow for fluid level adjustability, eliminating potential side connection installation errors. Typically, constant level oilers are mounted on the side of the equipment facing the direction of shaft rotation. Some oilers allow for bottom mounting, on the oil sump, which prevents the oiler from misfeeding during applications that contain currents and turbulence formed by slinger rings, discs, and high rotating speeds. In most cases constant level oilers are vented to the outside atmosphere to work properly. Since these oilers are vented to the atmosphere, Direction of shaft rotation especially in harsh, dirty environments, contaminants are allowed to enter the lubricating oil. These contaminants are in the forms of moisture and/or particulate which are extremely
