Basic Components of Hydraulics System

construction_blankThe most exciting part is to see the hydraulic system works.  What really amazing is that it is all off the simple Pascal’s Law.  When you look closely, there are some basic components needed to make the hydraulic system to work.  Here are some basic hydraulic components and roles that they play in the system below.

  • Hydraulic Cylinders: These components of the hydraulic system are those in which, pressure is applied on the fluids (oil), to get the desired force. The force acquired is used to power the hydraulic machine of car brakes, cranes, turbines and a large number of excavators. These cylinders also include the pistons of different sizes. The hydraulic pistons are used to push down the fluids in the other cylinder, which in turn exerts the pressure and pushes it back again.
  • Hydraulic Pumps: The hydraulic pump is a component that is responsible for supplying the fluids to the other essential parts of the hydraulic system. The power generated by a hydraulic pump is about ten times more than the capacity of an electrical motor. There are different types of hydraulic pumps such as the vane pumps, gear pumps, piston pumps, etc. Among them, the piston pumps are relatively more costly. But they have a guaranteed long life and are even able to pump thick, difficult fluids.
  • Hydraulic Wrench: A hydraulic wrench is used to tighten the nuts and bolts.
  • Hydraulic Lifts: Hydraulic lifts are the similar components used for powering the hydraulic system in cars such as the lowriders. These lift kits are available in any custom- made car shops.
  • Hydraulic Press: This is a process in which, the pressure is compressed to a full extent. The structure again involves two cylinders of different diameters and two different sizes of pistons. In order to generate a powerful pressure, the basics of Pascal’s Law are followed. The pressure is created by applying force and pushing the smaller piston through the cylinder and the fluids are pushed through the connecting pipe to the larger cylinder till a great pressure is exerted. The use of a hydraulic press is seen in the process of crushing cars. For crushing cars, a motor powers the hydraulic press. A car crushing hydraulic system has the capacity to generate about 2500 pounds per square inch (psi) and apply a force of about 200 tons that is more than enough to crush any car. A hydraulic press has the potential to crush an aluminum metal into a thin scrap of paper. The hydraulic press too is comprised of many components such as the pumps, the various valves, the pipes and the engine.
  • Hydraulic Motors: This is the one most widely used. The power in hydraulic motors is achieved with the help of exerting pressure on the hydraulic fluids, which is normally oil. The benefit of using hydraulic motors is that when the power source is mechanical, the motor develops a tendency to rotate in the opposite direction, thus acting like a hydraulic pump
