Hydraulic presses are pieces of equipment specifically designed to perform heavy lifting with precision. They use the power of fluids to deliver tremendous force: hydraulic fluid is conducted through machinery and motors, pressurized and controlled by hoses and valves. From small machinery to heavy equipment, the five main components of a hydraulic system remain the same. Hydraulic systems are designed to create motion, which then powers the machinery. It's important to understand the five main components of a hydraulic system so you can keep your hydraulic system running efficiently and determine which parts may need repair or rebuilding. Sapphire Hydraulics offers complete hydraulic sales and service in Houston, Texas. If your hydraulic system isn't running as efficiently as it used to, contact us for help. Here's a closer look at the five key components of a hydraulic system:

Hydraulic Cylinders:

Hydraulic cylinders provide the push and pull motion of hydraulic machinery. They can exert a variety of forces. Sometimes they are called linear hydraulic motors.

Cylinder Barrels, Cylinder Heads, and Pistons:

These components are inside the cylinder and work together to create different pressure zones. Whether these components are holding pressure, enclosing pressure chambers, or separating pressure zones, this is what helps the cylinder move.

Gear Pumps:

Gear pumps are often used for high-pressure purposes, such as steering or lubrication. They can be either internal or external and keep the system running smoothly, handling pressures up to 3600 psi. Internal pumps are usually used in smaller machinery, while external pumps are usually used in heavy equipment.

Hydraulic Hose:

Hydraulic hoses are designed with cost-effectiveness and environmental protection in mind. They are responsible for moving hydraulic fluid between and around various components. They also operate at high pressures, so while they are flexible, they are reinforced several times.

Hydraulic Filter:

Hydraulic filters are used to remove particles and contaminants from the oil inside the machine. Particles in the hydraulic fluid can increase wear on the machine and cause severe damage and reduced operating efficiency over time.
