Hydraulic systems are standard in a variety of large and small industrial applications. Construction equipment, heavy-duty vehicles, and manufacturing machines are some of the common examples of hydraulic items.
One of the main advantages of hydraulics is its capacity to produce repetitive movement at a lower cost than other power sources.
The hydraulic working principle
Hydraulic system specifications may vary, but the same concept applies when it comes to its working principle. The simple definition of a hydraulic system is creating a mechanical function using pressurised fluid. The power produced by a hydraulic system is significant, which is why it is preferred for heavy equipment and large machines. A unique characteristic of hydraulics is that the pressure applied to the fluid does not diminish at it moves through the system. The use and application of the force produced are efficient in functions such as lifting heavy loads.
Components of a hydraulic system
A hydraulic system is versatile. It can be used in stationary machines and mobile applications. A Mini Power Pack for hydraulics provides the perfect solution for portable or mobile hydraulic systems. Here is a list of the essential components used in hydraulics.
• Hydraulic circuit. The circuit is responsible for transporting the fluid through the system. Similar to electric circuits, it uses discreet and linear elements.
• Hydraulic pump. The pressure and flow coming from the hydraulic pump convert mechanical power into hydraulic energy. The pump functions by producing a vacuum in the pump’s inlet which in turn forces the fluid to the inlet line.
• Hydraulic motor. The hydraulic motor functions to convert pressure into twisting force or torque.
• Hydraulic cylinder. This is a mechanism that converts stored energy into enough power that will move the cylinder in a linear direction. A hydraulic cylinder is either double acting or single acting and has many applications.
Ensuring safety in hydraulic operation
Operating a hydraulic machine poses several hazards, which is why operators need to undergo safety training. Since the purpose of a hydraulic system is to create power or force, there are many ways that it can create great harm. Working with hydraulic power safely requires controlling the amount of energy produced by the system. To achieve control, you need to use an energy-isolating device which will prevent the physical release of power.
Hydraulic system applications
As a method of transmitting power, hydraulic systems are more economical compared to mechanical systems. Another advantage of hydraulics is that it is not susceptible to the limitations of the system’s component geometry.
Many industrial applications depend on automation for efficiency, and hydraulics are capable of providing the necessary power for various functions. The varied and extensive use of hydraulics span from a small and simple device such as a vehicle jack, to massive machines used in manufacturing.
In addition to the superior power of hydraulics, the system is also simple and easy to operate using straightforward levers and buttons. Hydraulics are also highly accurate and easy to control which makes it all the more convenient to use in industrial settings.
