Guide to Hydraulic Systems for Heavy Equipment: Definition, Design & Components
Guide to Hydraulic Systems for Heavy Equipment: Definition, Design & Components
CalendarPublished on September 26, 2024 by InfraJunction
Hydraulic systems play a crucial role in the efficient functioning of heavy equipment used in construction, mining, agriculture, and other industries. From excavators to dozers, hydraulic systems provide the force required to move large amounts of material, lift heavy objects, and perform various tasks with precision and control. Without hydraulic systems, modern construction equipment wouldn’t function as efficiently as it does today. Thanks to this fluid-based technology, heavy equipment can turn small operator actions into powerful movements for attachments and materials.In this guide, we’ll break down everything you need to know about hydraulic systems. This includes what they are, how they’re designed, and the essential components that make them so effective.Introduction to Hydraulic SystemA hydraulic system is a setup whereby any form of movement is done with the help of fluid under pressure. The more the pressure exerted on the fluid, the more it increases the force at the output. It then enables it to carry out heavy tasks with ease. Hydraulic systems are used in heavy machinery in either cylinders or power units for different purposes. This includes stopping a vehicle through brakes, lifting a crane and its load, or moving a bucket on a loader.In a hydraulic system, different components apply force to the un-compressible fluid. Because the hydraulic oil neither shrinks nor compresses, the applied force transfers to another end of the system. This pressure moves a large piston, which works alone or with other cylinders to handle tasks that require extra power.A hydraulic system lets you increase the work your equipment can handle without needing to put in more effort. In construction equipment, these systems allow a small joystick movement to lift a tractor bucket full of heavy rubble effortlessly.Without hydraulics, this kind of heavy lifting would be impossible for humans with just muscle power and shovels. For example, older steam-powered machines could move the same amount of material in a day that would take two people with a wheelbarrow two weeks to complete.As hydraulic systems have advanced, they’ve only made construction equipment more powerful, reliable, and efficient for handling the toughest jobs on-site.How Do Hydraulic Systems Function?Hydraulic systems are basically designed to do the basic requirements of lifting, reaching, and tilting in machinery, construction equipment. Such systems power the machines accurately in a smooth operating manner. It adds great value to efficiency and safety when compared with manual or non hydraulic methods.Hydraulics utilize the concept of fluid pressure in a closed circuit. Hydraulic oil is held in a reservoir in the machinery, moved through a valve, and then sent into a cylinder which controls movement of the machinery. The pressure from the liquid makes the component move. Thereby the machine will lift or tilt depending on the other mechanisms' support like hydraulic actuators and motors.In simple terms, hydraulic systems transfer force through fluid movement, making it possible to achieve tasks like lifting or tilting.Many wonder why heavy equipment relies on hydraulics instead of electricity or pneumatics. The reason is simple: hydraulic systems can lift heavier loads with greater force. They use fewer moving parts compared to other power systems like gears or pulleys, reducing the chances of breakdowns or wear. With hydraulics, you can lift heavy loads at a steady rate of power and torque, something other systems struggle to do as they lose power when speed increases. This makes hydraulics the preferred choice for heavy-duty tasks.Key Components of Hydraulic SystemsHydraulic systems are complicated networks consisting of various components. Each serving a particular purpose to give the desired output.Let's glance at major parts that constitute hydraulic systems to work:Hydraulic PumpsThe hydraulic pump would be considered the main part of the hydraulic system. The hydraulic pump draws in mechanical power provided by an engine or an electric motor. It then transfers it into hydraulic power by essentially spinning the fluid around. This creates a pressure inside that fluid. This fluid, at its pressure, is then pumped throughout the rest of the system. This strives to be able to do everything that needs force to be accomplished. Hydraulic pumps have an even flow and pressure to allow the proper functioning of the system.Hydraulic Cylinders or PistonsHydraulic cylinders, commonly known as pistons. They are capable of converting hydraulic pressure into linear force. These components are more often used in heavy machinery with the view to helping it move or lift objects easily. The generating of forces in hydraulic cylinders is affected by the use of pressurized fluid therein. That is the main reason hydraulic cylinders are important in a wide range of industries, such as but not limited to construction and manufacture of goods.ValvesThe hydraulic valves control fluid flow and pressure in the hydraulic system. They provide the operator with various options to manipulate the speed of the equipment in operation and magnitude of force exerted. The adjustment of the valves enables them to fine-tune their systems for specific operations. And also enables them to have better efficiency.FiltersFilters clean the hydraulic fluid to block it from carrying any contaminant. This includes dirt, debris, or moisture that will be ingested by the components and cause damage or decreased overall performance. Basically, what filters do is ensure that the service life of the hydraulic system is adequately extended and sudden breakdowns. And also costly repairs are reduced to a minimum.ReservoirsHydraulic fluid reservoirs are tanks used in storing hydraulic oil. They provide fluid to the system whenever it's needed. They also manage thermal expansion, adjusting for changes in fluid volume as the temperature fluctuates. Reservoirs also assist in separating air bubbles from the fluid. Hence allowing for the smooth running of the entire system with efficiency.These are some of the key components that make hydraulic systems function effectively. Together, these parts combine to deliver exceptional power and control, enhancing overall performance.How Does a Hydraulic Drive System Operate in Construction Equipment?The construction machinery has to handle a large load and big movements, and for that, there is a need for specialized solutions. It is here that among the regular cylinders, Hydraulic Power Units find a place to ensure greater power. In simple terms, Hydraulic Power Units are a must to operate big machinery with easeUnderstanding how these systems work can significantly help operators achieve the best results from their machinery. This knowledge ensures higher productivity at job sites.We’ll look at the components and how hydraulic drive systems work in construction equipment.Hydraulic Power Units (HPUs)HPUs pull more fluid at higher pressures, generating greater force over larger distances than small pistons. They deliver more force compared to two-cylinder systems.Components of HPUsIncludes pump, motor, and fluid reservoir in one unit. The pump and motor create necessary pressure.OperationWhen the system starts, the pump sends oil to the accumulator. Once pressure is reached, a larger piston moves, and a valve opens for fluid to return to the reservoir.Two-Stage PumpsAllows for faster movement by switching between high pressure/low flow and low pressure/high flow.Fluid ReservoirsMany HPUs require large reservoirs, holding dozens of gallons for machines with multiple cylinders.Hydraulic System FunctionsOperates various components in construction equipment:Tracked Backhoes: Use hydraulic drivers for tracks.Loaders: Two pistons for lifting, two for rotating, and others for opening sides.Dump Trucks: Usually need one or two cylinders to lift beds.Cranes: Use hydraulics for outriggers, load rotation, and boom movement.Operator ControlsControls in the cab change hydraulic fluid flow, allowing equipment parts to move.Spool ValvesConnect oil lines to the pump and each other, directing fluid to where it’s needed.Importance of HPUsIssues with the HPU’s motor, pump, or reservoir can disrupt productivity. Recognizing problems and getting repairs can minimize downtime.Types of Hydraulic SystemsHydraulic systems have different types. All types are designed for a specific use and need. Of these, two of the most common types are open-center systems and closed-center systems.List of Hydraulic Machines Used in ConstructionBelow is a list of common hydraulic machines used in construction, along with example models that are widely recognized in India.Hydraulic MachineCommon UsesExample ModelsExcavatorsDigging, trenching, material handlingJCB 3DX, CAT 320DHydraulic CranesLifting heavy loads, construction of tall structuresACE 14XW, SANY STC600SBackhoe LoadersDigging, trenching, material transportCASE 770, Manitou TLB 844SCompactorsSoil compaction, road constructionVolvo DD90B, LiuGong 611DozersEarthmoving, gradingCAT D6R, Shantui SD32WForklift TrucksLifting and moving heavy materialsVoltas 8FBS10, Godrej GRT 140E ConclusionHydraulic systems hold an important place in modern construction machinery for the supply of power and preciseness for heavy tasks. Be it excavators, cranes, compactors, or forklifts, hydraulics make the job of load handling much easier with reduced human effort. Understanding hydraulic system operations and main components is critical to getting optimal use out of the equipment. It will surely enhance productivity at site.As technology keeps advancing, hydraulic systems continue to improve, making construction machines stronger and ready to tackle even bigger challenges. Follow us for the Latest Infra Industry UpdatesFacebook - https://www.facebook.com/infrajunction/Instagram - https://www.instagram.com/infra_junction/
