The power plant’s Electrohydraulic Control (EHC) system plays a crucial role in the reliable operation of a power generation plant, and its efficiency depends on several key factors, including oil cleanliness and Total Acid Number (TAN). The EHC system utilizes EHC fluids like hydraulic oil, often a phosphate ester fluid, to precisely control and move critical components such as turbines, steam turbines, valves, and actuators.

The cleanliness of the oil is of utmost importance

Acting as a lubricant and coolant within the EHC system, any contaminants present in the oil, such as dirt, debris, or particles, can lead to abrasion, wear, and damage to both internal and external components of the hydraulic power unit. Such issues may result in increased friction, reduced efficiency, and, in severe cases, catastrophic failures. To prevent these complications, it is essential to conduct regular oil analysis and filtration to maintain the required cleanliness level. This proactive approach ensures smooth operation and extends the overall lifespan of the EHC system.

The Total Acid Number (TAN) of the oil is a critical parameter to monitor.

Hydraulic systems that contain acidic oil are prone to corrosion of metal surfaces and degradation of seals and gaskets. The presence of water and acids further accelerates the oil’s deterioration, compromising its lubricating properties and overall performance within the EHC system.

Regular monitoring of the TAN number

Monitoring through oil analysis allows for early detection of acid buildup, enabling timely maintenance actions like oil replacement or chemical treatment to neutralize acidity. By controlling the TAN within specified limits, the EHC system operates reliably, minimizing downtime, and mitigating the risk of costly repairs or unplanned shutdowns.

Use Fire Resistant Fluids

To address these challenges effectively, utilizing fire-resistant fluids, such as phosphate ester fluids, is highly recommended. These fluids not only offer improved fire safety in the power plant environment but also exhibit better resistance to degradation, reducing the risk of acidity formation (thereby, fluid degradation) and enhancing the longevity of the EHC system.

PIon Exchange Technology

Additionally, implementing ion exchange technology for water removal in hydraulic oil can significantly contribute to maintaining oil purity. Both old and new EHC systems can benefit from off-line oil filtration and water removal systems, which play a crucial role in ensuring the optimal performance of the EHC system.

In conclusion, the power plant’s electrohydraulic (EHC) system relies on various factors to operate reliably and efficiently. By focusing on oil cleanliness, controlling acidity levels with regular TAN monitoring, and utilizing fire-resistant fluids like phosphate ester fluids, the power plant can enhance the performance and safety of the EHC system. Additionally, incorporating ion exchange technology and off-line oil filtration further contributes to maintaining the purity of the hydraulic oil, ensuring uninterrupted operation and reinforcing the overall reliability and safety of the power generation plant.

In the realm of hydraulic systems, engineers often rely on the likes of a hydraulic accumulator and nitrogen to address various challenges such as energy storage, pressure regulation, and shock absorption.

Nitrogen, a prominent element constituting approximately 78% of the Earth’s atmosphere, plays a vital role in hydraulic systems, particularly in hydraulic accumulators. These devices serve critical functions such as energy storage, pressure regulation, and system stability.

We’ll delve into the reasons behind the extensive utilization of nitrogen in hydraulic accumulators, considering its impact on performance, safety, and broader environmental considerations.

We will also explore related key phrases such as carbon dioxide, boiling point, ammonia (NH3), piston accumulators, liquid nitrogen, atmospheric nitrogen, nitrogen compounds, and diaphragm accumulators.

Energy Storage and Pressure Regulation:

One of the primary reasons nitrogen is used in hydraulic accumulators is its ability to store energy effectively. These devices store pressurized hydraulic fluid, and by compressing nitrogen gas, potential energy can be stored for later use.

Nitrogen’s high boiling point, which allows it to remain in a gaseous state under normal operating conditions, and its ability to withstand high pressure make it suitable for this purpose. When hydraulic power demand arises, the pressurized fluid is released, converting the stored potential energy into kinetic energy, thereby driving actuators or performing work.

Safety and Stability:

In addition to energy storage, the utilization of nitrogen in hydraulic accumulators helps regulate pressure and maintain system stability. By serving as a cushion, nitrogen absorbs pressure fluctuations caused by variations in hydraulic pump flow or sudden changes in fluid demand.

This pressure regulation function helps stabilize the hydraulic system, safeguarding it against excessive pressure surges that could damage components or compromise safety. Additionally, nitrogen’s inert and non-reactive nature minimizes the risk of combustion or reaction with hydraulic fluid, further enhancing overall safety.

Nitrogen Compounds and Nitrogen Cycle:

While nitrogen gas (N2) is the most abundant element in the Earth’s atmosphere, it primarily exists as a diatomic molecule. However, nitrogen can be transformed into various nitrogen compounds, such as ammonia (NH3), through processes like the nitrogen cycle.

Although nitrogen compounds are not directly involved in hydraulic accumulators, understanding their role in natural systems highlights the versatility and significance of nitrogen in different contexts. The nitrogen cycle, which involves the conversion of atmospheric nitrogen into forms usable by living organisms, showcases the essential role nitrogen plays in sustaining life on Earth.

Environmental Considerations:

Considering the growing focus on environmental sustainability, the use of nitrogen in hydraulic accumulators raises important considerations. While nitrogen gas itself is not a greenhouse gas, its production process can contribute to carbon dioxide emissions. Industrial processes like fractional distillation of air are commonly employed to extract nitrogen from the atmosphere.

Consequently, manufacturers and engineers must strive to minimize the environmental impact associated with the production and utilization of nitrogen gas in hydraulic systems. Embracing energy-efficient manufacturing practices, exploring alternative nitrogen extraction methods, and optimizing hydraulic system designs can help mitigate the environmental footprint.

Types of Accumulators – Piston, Bladder and Diaphragm:

In hydraulic systems, three common types of accumulators are piston accumulators, bladder accumulators, and diaphragm accumulators. These devices utilize nitrogen gas for energy storage and pressure regulation. In piston accumulators, nitrogen is compressed behind a piston, while in bladder accumulators & diaphragm accumulators, a flexible bladder or diaphragm separates the nitrogen and hydraulic fluid.

All designs leverage nitrogen’s compressibility and inert nature to perform their respective functions efficiently. Engineers carefully select the appropriate accumulator type based on the specific requirements of the hydraulic circuit and system design.

Nitrogen, an abundant element in the atmosphere and a key component of hydraulic accumulators, plays a crucial role in enhancing performance, safety, and considering environmental sustainability in hydraulic systems Its properties, such as energy storage, pressure regulation, stability, and inertness, make it a preferred choice for maintaining system efficiency. By harnessing the unique characteristics of nitrogen, engineers can optimize the functionality, reliability, and safety of hydraulic systems, ensuring smooth operations in various industrial and mechanical applications.

As technology continues to advance, researchers and engineers are continuously exploring innovative methods and materials to further improve hydraulic system performance and minimize environmental impact. While nitrogen remains a prevalent and reliable choice for hydraulic accumulators, ongoing research is being conducted to explore alternative gases, materials, and designs that can further enhance the efficiency, safety, and sustainability of hydraulic systems.

In conclusion, nitrogen’s abundance, properties, and inert nature make it a valuable component in hydraulic accumulators. Its role in energy storage, pressure regulation, system stability, and environmental considerations showcases its significance in the field of hydraulics. By incorporating nitrogen into hydraulic system designs and adopting sustainable practices, engineers can achieve optimal performance, safety, and environmental responsibility, paving the way for a more efficient and sustainable future in hydraulic applications.

Electro-hydraulic systems combine the benefits of electrical signal processing with hydraulic drives to create versatile and reliable control systems. These systems can be categorized into three groups based on functionality, each offering unique advantages and applications.

1. Solenoids

The first group of electro-hydraulic systems uses solenoids to open or close hydraulic valves.

If you are looking to replace or retrofit a Hydraulic Power Unit, you need to understand the key components that have made modern HPUs smaller, quieter, and more efficient.

Gone are the days of being limited to just a fixed-speed Hydraulic Power Unit. In fact, the new variable-speed HPUs are far more energy efficient, and they are starting to dominate the market. Add in the fact that these new units include built-in sensors, diagnostics, and even cloud capabilities, making them very easy to connect to an IoT (Internet of Things) environment, and it’s fairly easy to see why they have become so popular. The sheer amount of predictive maintenance data alone makes the investment worth it!

The most important part of replacing a Hydraulic Power Unit is understanding how the modern hydraulic system design differs from the older conventional systems in aspects like size, noise, energy efficiency, connectivity, and total cost of ownership. Let’s take a look at those differences…

The Main Differences Between Conventional and Modern Hydraulic Power Units

Hydraulic Power Unit Size

HPU size is often determined by the size of its hydraulic fluid reservoir. For traditional HPUs, the reservoir minimum is normally two to five times the maximum pump flow.

Conversely, modern HPUs can be designed to a 1:1 flow/reservoir size ratio due to pump controls, advanced manifold design, and the use of variable frequency-driven motors to drive the pumps. As a result, a unit that produces a max flow of 150 GPM per minute may only need a reservoir capacity of 150 gallons, or 75 percent less reservoir capacity than a traditional HPU.

Hydraulic Power Unit Noise

By operating at variable speeds, modern units are quieter because they don’t demand their full power at all times. Instead, they are only delivering the power needed at any given time.

Furthermore, modern systems can be built from materials that dampen sound and minimize vibrations by using designs like a liquid-cooled motor, compact arrangement of components, unitary housing, and built-in sound-insulating mats.

Hydraulic Power Unit Energy Efficiency

A fixed-speed HPU operates at 100 percent motor speed at all times. In turn, any energy not being used to do work is converted to heat. This all results in higher energy costs and excess heat production that must be controlled using cooling – which requires even more energy.

Variable-speed systems adjust energy output to match the demands of the operation. As such, variable-speed HPUs have demonstrated energy savings of up to 80 percent. Lower, more controlled operating speeds also reduce the unit’s heat output, allowing it to run cooler and reduce or eliminate the need for additional cooling measures and their associated costs.

Hydraulic Power Unit Connectivity

With a modern HPU, access to cloud-based diagnostics and data analytics tools streamlines workflows and reduces the demand for personnel to capture critical data and troubleshoot equipment in person.

Some HPUs include case drain flow/temperature, particle counter, energy consumption, pump damage, and other monitoring parameters, with real-time access to performance and usage reports 24/7 via dashboards on a mobile device.

Hydraulic Power Unit Total Cost of Ownership

Modern variable-speed HPUs may be more of an investment upfront, but manufacturers with high energy costs driven by fixed-speed HPUs will see more value and a faster return on their investment.

Atlantic Hydraulic Systems has designed, manufactured, and commissioned many key elements in the fight against the rising tides of the world.

We live in a busy society that is dependent on our ability to travel, transact business, gather at social events, and connect with other humans on multiple levels. With each passing day, however, our need to connect is also contributing to adverse effects on our planet.

The Earth’s Temperature Is Slowly Rising And Our Water Levels Are Rising Along With It

Ultimately, the earth is getting warmer and that increase in temperature – however subtle or blatant it may be – is contributing to higher ocean tides and rising water levels on a global scale.

Our oceans absorb over 90% of the excess heat generated by our planet and that is throwing some major complications into the delicate ecosphere. Increases in temperature are adding to the overall water volume on the planet by melting giant ice sheets and glaciers. This, thereby, contributes to sea level rise.

As sea levels rise, there’s an adverse effect on our lands, weather, and the frequency of floods in areas that are otherwise usually free of flood dangers.

To that end, our society is placing ever more emphasis on stormwater management, flood protection, and water control gates to either mitigate damage or outright prevent damage from rising water levels.

Atlantic Hydraulic Systems Is Playing A Major Role In Mitigating And/Or Preventing Unnecessary Damage From Rising Tides

In turn, Atlantic Hydraulic Systems has designed, manufactured, and commissioned many key elements in the fight against the rising tides of the world including Hydraulic Power Units, Hydraulic Control Panels and Hoist Winch Control Panels for water control management systems like Crest Gates, Sluice Gates, and Tainter Gates.

Important aspects in the hydraulic power unit and control system design for Crest, Sluice, and Tainter Gates are:

Designing for emergency gate closure and opening in a no-power condition
The ability of the gate hydraulics to detect gate blockages while moving to protect the structure
Gate position feedback and monitoring
Design for no single-point failure event possibility using redundant pumps & controls
Ability to control operation locally or via a SCADA system – which is a control system architecture for high-level supervision of machines and processes.

Our Recent Projects To Help Combat The Effects Of Floodwater and Rising Tides

Atlantic Hydraulic Systems designed, manufactured and commissioned the floodgate hydraulics and control systems at Seabrook Gates in New Orleans. Atlantic’s on-site technicians directed the installation of the HPU, hydraulic cylinders, hydraulic plumbing, and both high voltage and control wiring.

The gates are controlled using a user-friendly graphic interface and provide closed-loop position control of the gates and safety interlocks with the gates locking mechanisms.

We even designed, manufactured, and installed the hydraulic system for the Orleans Avenue Gates in New Orleans, LA after Hurricane Katrina. Five hydraulically driven winches were placed to lift and lower massive gates to prevent water flow in the canal during a storm. The HPU is designed to communicate with the municipal SCADA systems as well as to be run manually.

Most Recently, after Hurricane Sandy, we were commissioned to design and manufacture both the temporary and permanent hydraulic systems during the Metropolitan Ave Bridge machinery replacement in New York, NY. Now, two of our 60 HP hydraulic power units and four 10″ bore x 96″ stroke cylinders drive the two massive leaves of the bridge in addition to four of our 7.5 HP hydraulic power units which drive the tail locks into place.

We at Atlantic Hydraulic Systems may not be able to control the earth’s temperature – but we are certainly at the forefront of how we can prevent or mitigate any damage of the rising tides or flooding that may be happening as a result.

So, if you are in the business of creating memorable entertainment in such a competitive atmosphere, how do you do it? In fact, how do you do it and keep it going for twenty years?

Well for Cirque du Soleil and the MGM Grand Hotel, the show DOES go on… twenty years later.

In conjunction with McLaren Engineering, the stage for the Cirque show “KA” is still being lifted in the air by Atlantic Hydraulic Systems.

Now the term stage may be an understatement. This is actually the world’s largest stage, weighing in at 200 tons, and lifting 70 feet in the air at two feet per second as it tilts 100 degrees. It’s a marvel that truly challenges people’s perception… accomplished through a 4,000-horsepower hydraulic power unit and control system designed, engineered, and manufactured by Atlantic Hydraulic Systems.

Little did the audience know on opening night in February 2005 how long the stage took to become reality… with a phone call three years prior. All they saw was a show that seemed to defy gravity… a fact that did not escape the New York Times as they entitled their review “Fire, Acrobatics and Most of All, Hydraulics.” And 20 years later, the show is still making people gasp with delight and terror at the same time.

So obviously something so complex with functionality that was almost unthinkable had its share of challenges. The answer is a resounding “Yes”. Tuning a hydraulic system that sits on (4) 12” bore cylinders x 70-foot stroke had its “moments”. The stage, when in the elevated position, sits on about 1600 gallons of oil, rendering the hydraulic natural frequency of the system incredibly low (basically, it’s a big spring). However with a peak system flow of 2200 GPM at 4000 PSI, system failure was not an option. So, all hydraulic pumps, valves, and controls have redundant and/or soft-landing functionality in case of a component malfunction.

The Atlantic team spent months at the MGM Grand making alterations to the hydraulic system, fine-tuning the hydraulic motion control, and testing and retesting. The result was a reliable hydraulic system that 20 years later has proven its reliability and resiliency.

KA was just one of many entertainment projectsthat depend on Atlantic firepower utilizing its hydraulic power units & hydraulic controls. These include Broadway shows such as The Lion King, Wicked, Phantom of the Opera, Les Misérables and many more.

For the first time in over three decades, new nuclear reactors are under construction in the United States at Georgia Nuclear Power Plant – The Vogtle Electric Generating Plant

Atlantic Hydraulic Systems is providing a key component to the new reactors at the Vogtle Electric Generating Plant in Georgia: Turbine Jack Oil Systems.

What Is A Turbine Jacking Oil System?

Atlantic’s Turbine Jacking Oil Pumps are specially designed to reduce high friction in turning gears between rotor and bearings during start-up of a turbine and then shut down

In other words, the jacking oil pump is used in large turbine systems (like those found in a nuclear reactor) to prevent metal-to-metal contact in the bearings during turbine start-up.

How Does The Turbine Jacking Oil System Function?

The Turbine Jacking Oil System essentially lifts the heavy turbine rotor shafts until the turbine itself is spinning fast enough to create dynamic lift.

More specifically, the heavy rotor is prevented from rubbing against the bearing’s white metal or babbit bedding area at low speeds through the production of a hydrostatic oil film when the rotational speed is too low to produce a hydrodynamic oil film (or self-lubrication).

This hydrostatic film reduces the break-away torque during the run-up of the turbine rotor during high friction start-up, shut down, and slow speed (turning gear) periods.

How Are The Turbine Jacking Oil Systems Going To Specifically Help The Vogtle Electric Generating Plant?

The two new Georgia Power Co. reactors at the Vogtle Electric Generating Plant will account for 2500 MW of power produced by Westinghouse AP1000 Power Plants.

The seven jacking oil pump packages from Atlantic Hydraulic Systems are required for the low-pressure turbine and generator bearings which are mounted on support platforms attached to or adjacent to the turbines and generator.

The pumps are specifically capable of producing 1.5 GPM @ 3500 PSI to the bearings.

Other features of the systems include ASME system relief valve, pump pulsation dampener, non-bypass 5-micron hydraulic filter, pressure & differential pressure feedback instrumentation.

Why Are The New Nuclear Reactors A Big Deal?

The new Plant Vogtle units 3 and 4 are the first new nuclear units built in the United States in the last three decades. Once complete, the addition of the new Vogtle units will give the plant enough capability to produce safe, reliable, affordable electricity to power one million Georgia homes and businesses.

Chapman is managing Atlantic’s Mobile Launcher 2 Hydraulic Systems Project for NASA’s new rocket program which looks to put the first woman on the moon as early as 2024.

SHIRLEY, NY – March 11, 2022 (Atlantic Hydraulic Systems): With the Artemis Program – NASA hopes to put the first woman on the moon as early as 2024, and Atlantic Hydraulic Systems is answering the call by naming Christina Chapman as project manager for a critical system they are developing to help NASA’s launch effort.

Chapman is managing the NASA Mobile Launcher 2 (ML2) Hydraulics Systems Project which is specifically used for NASA’s new SLS rocket program. While much of Chapman’s work is classified, Atlantic’s president, Robert Ferrara, notes “the hydraulic systems [Chapman is managing and helping design] will supply the launch actuators with high-pressure hydraulic fluid during the liftoff sequence”. The ML2, and the new SLS rocket, will spark the imagination of lunar travel for a brand new generation of men and women for years to come.

Ms. Chapman says of her role, “I have been able to jump right into new, exciting projects in my short time at Atlantic, like the ML2 Launcher unit. I am looking forward to continuing to grow my skill set and knowledge with the team at Atlantic.” Chapman started at Atlantic in January 2022.

Chapman worked for nine years at Portsmouth Naval Shipyard as a mechanical engineer in the Nuclear Engineering department specializing in Reactor Plant cleanliness and Reactor Plant system valves. Now she finds herself as a key member of the Atlantic team to aid NASA’s ambitious goals.

Per NASA, “With Artemis missions, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before.” NASA hopes to “collaborate with commercial and international partners and establish the first long-term presence on the Moon…and use what we learn…to take the next giant leap: sending the first astronauts to Mars”. Another intention for Artemis to go back to the moon is to motivate a new generation of potential explorers NASA has dubbed, “The Artemis Generation”.

Atlantic Hydraulic Systems is proud to serve its part in the historic Artemis program and is excited to add its 38 years of experience to the project. Atlantic is also excited to name an incredible talent like Christina Chapman, during National Women’s Month, to lead their contribution to NASA’s effort to return to the moon and explore the far reaches of space.

The powerful Hurricane Ida was a deadly and destructive Category 4 Atlantic hurricane that became the second-most damaging storm to ever strike U.S. soil, just behind Katrina. It also caused catastrophic flooding across New England.

What Are Levee Gates?

A levee is a man-made structure designed to control the flow of water and debris to prevent flooding. Levees are used across the world in areas close to sea level to protect lives and infrastructure. The hydraulically operated levee gates open the levees to allow marine traffic to pass through the protected waterways during normal weather conditions

These levees are critical in New Orleans, which is constantly at risk of severe flooding.

Hydraulic Levee Gates In New Orleans

Back in 2010, the Army Corps of Engineers invested $14 Billion in fortifying the New Orleans Levee system to protect the city.

Although there were a handful of hurricanes to hit the area, Ida was the first major Hurricane to challenge Atlantic Hydraulic Systems’ 17 hydraulically powered levee gates that protect New Orleans.

Our team was honored with the engineering, manufacture, and commission of the hydraulic power units and PLC control systems for the levee gates.

One key in the system’s design is that it’s protected from the extremely corrosive environment in the New Orleans area. Therefore, our engineers specified a great deal of stainless steel hydraulic components on the projects.

Rigorous maintenance programs and hydraulic oil testing & conditioning played a considerable role in the recent successful gate operation that prevented catastrophic flooding.

Have you ever sat down and wondered to yourself, “How does a hydraulic press work?” We actually think about it all the time here at Atlantic Hydraulic Systems.

The fundamentals of a hydraulic press were actually made possible because of a French philosopher named Blaise Pascal. In fact, Pascal theorized and developed what we now know as Pascal’s Law.

In this article, we’ll delve into Pascal’s Law, the mechanics of hydraulic presses, exploring the force exerted, pressure applied, and the fascinating principles that make them tick.

What Is Pascal’s Law?

A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid and acts at a right angle to the enclosing walls.

How Does A Hydraulic Press Work?

Hydraulic presses harness the hydraulic principle, a concept grounded in Pascal’s Law, to perform various tasks. This hydraulic principle dictates that any pressure applied to an incompressible fluid within an enclosed system will be transmitted uniformly in all directions.

In a hydraulic press, there are two interconnected cylinders: a larger cylinder and a smaller cylinder. High-pressure hydraulic oil is supplied to the larger cylinder, creating an increase in pressure. As per Pascal’s Law, this increase in pressure is transmitted undiminished throughout the fluid. Consequently, it exerts a substantial amount of force on the piston within the larger cylinder.

This force is then leveraged to extend the larger cylinder, which in turn exerts pressure on the object being pressed. The mechanical force applied to the smaller cylinder is multiplied many times over, resulting in a force exerted on the object that is significantly greater than the initial force applied to the hydraulic system.

This process is a direct application of Pascal’s Law. The law states that the pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.

You may have already seen the damaging effects of a hydraulic press on everyday household items in YouTube videos. Still, a hydraulic press is even strong enough to flatten a solid natural diamond in an instant!

Why Use Hydraulic Presses?

The application of hydraulic systems in presses includes various benefits, making them a preferred choice over mechanical alternatives:

Cost-Effective: Hydraulic presses are a cost-effective solution for a wide range of tasks.
Durability: They are known for their durability and minimal breakdowns.
Precise Control: Hydraulic systems offer precise control over the amount of force exerted and the speed of operation.
Noise Reduction: Hydraulic presses operate more quietly than their mechanical counterparts.
Power Amplification: These systems can efficiently convert a small input of power into a substantial force output, illustrating the power of Pascal’s Law.

In addition to their use in presses, hydraulic systems find applications in various fields, including hydraulic brakes and numerous industrial processes. The capacity to harness the hydraulic principle and Pascal’s Law in hydraulic presses demonstrates the remarkable efficiency of incompressible fluids in transmitting force and pressure.

Understanding how a hydraulic press works involves appreciating the fundamental hydraulic principle governed by Pascal’s Law. This principle allows hydraulic systems to magnify mechanical force many times over, making them indispensable in various industries and applications.
