Maintenance troubleshooting best practices for fluid power

An accumulator stores energy to maintain pressure, dampen vibrations and pulsing, and improves the efficiency of the system. They are pre-charged with an inert gas, typically nitrogen. A moveable barrier, usually a piston or rubber bladder separates the oil and gas. The gas is usually pressurized to 80-90% of the working pressure of the system.

Seal Oil System

The seal oil system prevents gas from leaking out of the compressor case. Fig. 8.46 is a schematic of a typical seal oil system working in combination with a buffer gas system. These systems require auxiliary equipment such as pumps, regulators, filters, and so on for proper operation. The oil that flows across the outboard ring mixes with the bearing lube oil and

Understanding the Purpose and Function of an Oil Accumulator

Emergency backup power: Oil accumulators serve as a reliable backup power source in situations where there might be a sudden loss of the main power supply. They can provide essential power to critical systems, such as emergency shutdown valves or safety systems, ensuring that they continue to operate even during power failures.

Hydraulic System Accumulator: Functions, Types, and Applications

Emergency power source: In case of power loss, an accumulator can provide temporary power to critical components and allow for controlled shutdowns. Types of Accumulators. There are various types of accumulators used in hydraulic systems. The most common types include: Bladder Accumulator: It consists of a flexible bladder inside a pressure vessel.

Power Oil

As the name implies, it is meant for supplying oil to the control circuit of the turbine load and/or speed controller and hydraulic power oil for operating the On–Off interceptor and modulating duty hydraulic governor valves (Figure II/3.2-2).This part of the control and hydraulic power circuit is popularly called an electro-hydraulic governing (EHG) system.

Guidelines for Understanding and Maintaining Hydraulic Accumulators

An accumulator should bear a safety sticker that warns against pre-charging with any gas but nitrogen. New accumulators come with such stickers, but they often are scratched off or painted over. A charging rig should be used to pre-charge an accumulator. The pre-charge should be performed with no oil in the accumulator.

Lube Oil System Accumulator (LOSA)

A lube oil system accumulator (LOSA) is a component in a lubrication system that stores lubricant. The LOSA collects and releases lubricant as necessary to keep the oil level consistent in the system. Without an accumulator, the oil level would constantly fluctuate, which could cause damage to the machine.

6 FAQs about [Power plant lubricating oil accumulator]

Do lube oil systems need accumulators?

Clients with critical lube oil systems without accumulators will often install them eventually, after experiencing unit trips that can easily justify the modification costs. This best practice has been used since the 1990s when FAI performed numerous field audits for auxiliary systems.

What is lubricating oil system?

The lubricating oil system is usually used for both the gas turbine and generator. Its main function is to take lube oil from the tank, pump it to high pressure and use in the turbine and generator hydraulic system. This system usually includes:

What is a common gas turbine lube oil system?

The compressor lube oil system is often common to the driver lube system but in some cases, separate lube systems are supplied. Fig. 8.47 shows a typical common gas turbine compressor lube oil system. Fig. 8.47. Typical common gas turbine compressor lube oil system. Dipak K. Sarkar, inThermal Power Plant, 2017 Lube Oil System of Steam Turbine 137

How many accumulators do you need to feed lube oil?

To enable the lube oil system to feed oil at rates of 400-500 gallons per minute, for example, at least 100 gallons of oil must be stored under high pressure. That may require 8 or 10 accumulators tied together to provide the necessary volume of oil.

What type of pump is used for Lube & control oil systems?

Process gas or air-driven turbines and quick-start steam turbines are often used to drive the emergency pumps. The pump capacities for lube and control oil systems should be based upon the particular system's maximum usage (including transients) plus a minimum of 15%.

What is an oil accumulator?

An accumulator is a pressure vessel that stores oil and contains a mechanical means of maintaining pressure when the pump shuts down, thus cushioning fluctuations in oils pressure. Accumulators differ on the type of mechanical means used, such as spring, gravity and gas load. Spring accumulators use a spring-loaded position in a cylinder.
