The oil sumps within an engine oil system require a minimum of two oil sumps distributed along the main shaft line, and sometimes more than four. To ensure the oil is retained within the oil circuit, each oil sump is pressurised and sealed. However, it is vital that the pressure inside the oil sump remains lower than the pressure outside the sump.
Understanding the basic methods and procedures of oil sump lubrication is beneficial as it can result in a very low cost, low maintenance, and a reliable system of equipment lubrication. Although simple in design, complexity arises around the application. Knowledge of the relationships between oil type, oil level maintenance, shaft speed and bearing housing design are important to determine the correct application.

If the level of lubricant is either too high or too low, excessive heat can be generated, in turn accelerating the degradation of the oil and shortening the life of the bearing. If the oil level is too high, a condition often referred to as ‘churning’ can occur. In this situation, air is whipped into the oil, which along with the induced heat raises the oxidation rate, shortening the effective life of the oil. Too little oil means there is not sufficient contact to lubricate the bearing and act as a heat sink to carry away the normal levels of heat generated by the bearing.
If you are experiencing problems with the sump, it could be due to poor oil sump lubrication. One of the most common causes of this is contamination of the particles within the oil. When the oil becomes contaminated, it can often result in wear of component parts, making aircraft less efficient and more costly, as these parts need to be replaced to maintain the safety of the aircraft. ExxonMobil aviation lubricants undergo strenuous testing, manufacturing and packaging processes in order to ensure all products avoid contamination and thus help your aircraft to operate at its maximum potential.
