The control oil system is another indispensable component of the lubrication system. The duty of this is to regulate and control many kinds of various functions within the gas turbine, ensuring its safe and efficient operation. This system is responsible for controlling fuel flow, maintaining temperature, and governing the turbine’s speed.
How the Gas Turbine Lubrication System Works
This System, is the heart of any gas turbine. This part functions by providing essential lubrication, cooling, and cleaning to critical components. It starts with an oil reservoir, pumps circulate oil, filters remove contaminants, and heat exchangers cool the oil. Valves and control mechanisms regulate oil flow, while monitoring systems ensure optimal operation. Regular maintenance is key to its performance and longevity.
Main Components of the Gas Turbine Lubrication System
In the realm of gas turbines, comprehending the main components of the lubrication system is pivotal. Let’s delve into these critical elements that ensure the smooth operation of these powerful machines.
1-Main Oil Pump

Its primary responsibility is to circulate the primary turbine oil throughout the system, delivering vital lubrication to essential components. This continuous oil flow is crucial for minimizing friction and wear, allowing the turbine to operate efficiently and reliably.
2-Auxiliary Oil Pump
Auxiliary oil pumps has an important duty in enhancing the reliability of the lubrication system. These pumps serve as backups or additional pumps to ensure continuous oil circulation. In the event of a primary pump failure, auxiliary pumps step in, preventing oil starvation and safeguarding the turbine’s health.
3-Emergency Oil Pump
Emergency oil pumps are the last line of defense in critical situations. These pumps are designed to activate under extreme and hard conditions, ensuring lubrication and cooling system, even when all else fails. Their robustness and reliability are paramount for preventing catastrophic turbine failures.
4-Oil Jacking Pump
Oil jacking pumps are instrumental in preparing the turbine for operation. They ensure that critical components are adequately lubricated before the turbine starts operating. This pre-start lubrication is vital for reducing initial friction and wear, contributing to the overall efficiency and longevity of the turbine.
5-Oil Pump Control
Oil pump control mechanisms are the brains behind the lubrication system. They govern the operation and flow of oil, optimizing the system’s performance based on the turbine’s needs. These control systems has to make sure that the right amount of lubrication is delivered to each component, preventing wastage and maximizing efficiency.
6-Hydraulic Accumulator
Hydraulic accumulators, though often overlooked, play a vital role in the gas turbine lubrication system. These ingenious devices store pressurized hydraulic fluid, acting as a source of instant power when needed for specific turbine functions. Imagine them as energy reserves, ready to spring into action to ensure the turbine’s smooth operation.
7-Valve Relief
In the intricate dance of the turbine lubrication system, valve relief components take on the role of protectors. They safeguard the system from overpressure by releasing excess oil, ensuring that the system operates within safe limits. These unsung heroes ensure the system’s stability and longevity.
8-Low-Pressure Double Filter
Amidst the relentless flow of oil, low-pressure double filters quietly carry out their duty. These unassuming components are essential for removing contaminants from the oil, ensuring that the lubrication remains clean and efficient. They act as the first line of defense in system against impurities (As we know like dust, water and etc.) that could compromise the system’s performance.
9-High-Pressure Double Filter
When it comes to high-stress areas within the lubrication system, high-pressure double filters step up to the plate. These filters are dedicated to maintaining oil purity, especially in parts of the system subjected to extreme conditions. Their efficiency is paramount in preserving the integrity of the lubricant.
10-High-Pressure Filter
Oil refinement reaches its peak with high-pressure filters. These components ensure that the oil meets stringent cleanliness standards, leaving no room for compromise. Their role is crucial in guaranteeing the quality of the lubricant circulating through the system.
11-Oil Vapor Separator
In the quest for consistent lubrication, oil vapor separators step in to eliminate any vapor or air bubbles present in the oil. These seemingly subtle components are instrumental in preventing cavitation, a phenomenon that can damage the system. By ensuring a bubble-free flow, oil vapor separators contribute to the system’s reliable operation.
12-Tank
Tanks are the sturdy reservoirs that serve as the lifeblood of the gas turbine lubrication system. These containers hold the vital turbine oil, ensuring a constant and reliable supply for the system’s various needs. Think of them as the beating heart of the lubrication system, ready to deliver the life-sustaining oil at a moment’s notice.
