Components Of the Lubrication System of Gas Turbine Engines

February 11, 2024

A turbine engine's gas systems can also ensure a pressure relief functionality that manages a somewhat constant pressure. The entire flow type of lubrication system, in which the pressure changes according to the engine speed. Also, the total loss system employed in a gas turbine engine is for short operations such as: targeting drones and missiles.

Large fan-type engines are widely used lubrication systems for the pressure relief system and the complete flow. The critical function of the oil and gas system in turbine engines is to provide a cooling effect to the bearings by overcoming the heat by circulating oil around the bearings.

Gas turbine engines employ both wet & dry-sump lubrication. Wet-sump engines safely keep the lubricating oil in the engine properly. On the other hand, dry-sump engines can be used for an outer tank mounted on the.

4 Components of Gas Turbine Engine

Many Components are part of a gas turbine engine, such as bearings: a lubricant supply system lubricates a gas turbine engine specifically. It includes a significant lubricant moving circuit and an auxiliary lubricant rotating circuit.

It ensures a sufficient lubricant supply to the lubricating chamber and chambers beneath all operating situations. The circulatory circuit is known as the engine start-up & for replenishing lubricant into the primary circuit during normal flight conditions.

The following elements' descriptions consist of the multiple turbine lubrication systems. You will find many components in different types of turbines. You can't find all the parts in one system because they vary from system to system. Here we are discussing some vital lubrication of gas turbine engines.

  • Oil Tank

Usually, it has an oil pump, scavenge & pressure inlet strainers, pressure outlet ports, and an oil filter. It also has mounting bosses for the oil pressure control and temperature bulb linkages.

A typical oil tank is developed to furnish a plentiful oil supply to the turbine engine during any. This process in a gas turbine engine is completed by a swivel outlet assembly mounted on the inner side of the oil tank, a horizontal baffle mounted in the middle of the tank, and two flapper check valves fixed on the baffle.

Expansion space is ensured in all oil tanks. This permits the expansion of the oil after the temperature is absorbed from the bearings & gears. A few oil tanks also come up with a deaerator tray for separating air from the petroleum returned to the upper side of the tank by the scavenger system.

Typically, these deaerators are one of the types of gas turbine engines in which oil reaches a tangent. The air released is done via the vent system on the tank's upper side.

  • Oil Pump

The oil pump develops to supply oil beneath pressure to the turbine engine's components that need lubrication and then circulates the oil via coolers as required. Also, it returns the oil to the tank of oil.

Many oil pumps not only consist of a pressure supply element but also scavenge components, such as in a dry-sump system. Therefore, a few oil pumps provide just a single function. Also, they scavenge the oil.

These pump components are located separately and managed by multiple shafts from the turbine engines. The number of pumping components and pressure depend significantly on the kind and model of the gas turbine engine.

Different scavenge oil pump parts assist the larger oil and air mixing capacity. The scavenge parts have a larger pumping capacity than the pressure element to prevent oil from gathering in the bearing sumps of the turbine engine.

The gear-type oil pump has only two parts: one for pressure oil & the other one for scavenging. However, a few types of pumps may have different elements: one or more than one component for pressure and two or more for scavenging purposes. The clearances in the middle of the gear teeth and the edges of the pump wall and plate are essential to managing the accurate output of the pump in a gas turbine engine.

  • Turbine Oil Filters

Turbine oil filters are crucial components of the lubrication system because they mitigate the foreign particles available in the oil. This is important in gas turbines to ensure the fastest speed: the antifriction ball and roller bearings will harm quite fast if lubricated with contaminated oil.

Also, you can find multiple drilled or core flows leading to different lubrication points. Since these flows are usually relatively small, they clog very easily.

The filtering component or interior is designed with various materials such as paper and metal mesh. Usually, oil flows via the filter element from the outer part into the filter body. One kind of oil filter is used as a replaceable laminated paper element. On the other hand, the other filters use an excellent stainless steel metal mesh top to ensure this process in the gas turbine engine.

  • Oil Pressure Relief Valve

A few extensive turbofan oil systems don't have a regulating valve. The system pressure is different according to the engine rpm & pump speed.

You can find different types of pressure in the gas turbine engine.

This existing relief valve system relieves pressure and bypasses the preferred oil back to the inlet side of the oil pump. This process is done whenever the pressure crosses the maximum preset system limit.

This relief valve is critical when oil coolers are incorporated into the system since the coolers are ruptured because of their thin-wall construction system. It should never open in normal conditions.
