What is a Hydraulic System?


Over the course of this year we will help advance the general knowledge & understanding of Hydraulic Systems

with a series of monthly newsletters...




Basic Hydraulic Principle:


Force

Transmission


Hydraulic fluids are incompressible, and the system is able to multiply a force - thru the fluid - to move & manipulate much larger objects.


220 lb (100kg) force can move

a 2,200 lb (1,000 kg) object

(ratio of the two cylinder areas is key)

Key Components of a Hydraulic System

Key Elements of a Hydraulic System:

Reservoir holds excess system fluid, it's the fluid that delivers Motion & Force

Pump provides Flow to the System

Valves determine where the Flow goes & what it does

Relief Valve or Pressure Regulator governs maximum system pressure

Cylinders/Motors are linear(push/pull) & rotary(spin) actuators that do work

Hoses & Fittings connect all components to complete circuit flow



Fluid Power systems are used in:

Excavators, Presses, Lifts, Brakes, and other Industrial Equipment

because they provide the ability to finely control large forces.

Fundamentals of Hydraulics Classes

Our week-long sessions include two major components of training:

Our "Hands-On" training

helps students understand fluid power functionality with actual system components.
