Hydraulic Components and Their Functions

Blog | April 13th, 2016

An operator moves a lever in a control cabin, fluid-driven circuitry responds instantly, and large quantities of power are transmitted through a branching network of tubes and hoses. The released power triggers mechanical pistons and other types of actualizing mechanical parts, massive moving parts that respond to the control inputs in the cabin and the actions of hydraulic components. Let’s take a look at these components and gain an insight into their functions.

Hydraulic Liquids

Strictly speaking, fluid is the most important component in the system, for nothing can take place without this medium. Pascals’s Law states that fluid power is equally distributed throughout an enclosed system. Typically supplied in oil form, the liquid expresses non-compressible characteristics, uniform viscosity, and superior thermal stability.

Control Valves

Multifunction valves control binary actions, directional regulation, and flow management. The mechanical valves switch direct flows ON/OFF, act as a system distributing manager, and regulate the velocity of the oil so as to express power in analog form. These clarified forms fall into the following categories:

  • Directional valves
  • Flow controls
  • Pressure-Control valves

These hydraulic components are fundamentally responsible for reacting to control inputs sent from the control cabin. They also add feedback mechanisms and automated features to complex hydraulic systems.

Pump and Reservoir

In the same way electrical circuitry requires a power source, hydraulic systems need energy. A positive displacement pump translates mechanical action into fluid power, which, in turn, places a vacuum on an inlet line and draws oil from the reservoir. The point is, the entire system load generated by this mechanical prime mover can be converted into pure fluid power and used to move operator-actualized metal assemblies or powered tools, which makes for a formidable amplification of relatively small input actions.

Hydraulic Actuators

Large pistons move linearly to power hydraulic crushers. Hydraulic motors lift loads and rotate to wind massive cable drums. Actuators are located all through the system, but they function best at the terminating point as drive mechanisms. Manufactured as single and double-acting mechanical assemblies, the fluid in the system engages each actuator, thus providing the muscle to move large loads. The pump-derived energy enables cranes to lift, voltage-free tools to rotate, and generates a wide range of magnified outputs from relatively small inputs.

Having covered the headlining parts of the system, hydraulic components also encompass seals, hoses, pressure gauges, and any number of system extras that work to partner fluid mechanics with physical parts.
