Hydraulic Jack | Working | Advantages & Disadvantages

Before directly jumping on to Hydraulic Jack, let’s first recognize ‘Jack’. A jack could be a device that is employed to carry significant weight. A jack can be Mechanical, Electrical or Hydraulic, according to the tactics of force generation. In this article let us focus only on Hydraulic Jack.

A hydraulic jack works on the idea of Pascal’s law. In 1838 William Joseph William Curtis filed a British patent for a hydraulic jack. In 1851, artificer Richard indignation was granted a patent for a “portable hydraulic press” – the hydraulic jack, a jack that proved to be immensely superior to the screw jacks in use at the time.

What Is A Hydraulic Jack?

A hydraulic jack could be a device that carries a significant weight by applying a force via a hydraulic cylinder. Hydraulic jacks carry weights by the force created by the pressure within the cylinder chamber.

How Do Hydraulic Jacks Work?

A hydraulic jack creates pressure by moving oil through 2 cylinders via a pump plunger. The pump plunger is drawn back, that opens the suction valve and attracts oil into the pump chamber. Because the plunger is pushed down, the oil is transported through an external discharge valve and into the cylinder chamber.

The suction valve then closes, leading to pressure being stored up within the chamber; inflicting the piston within the chamber to rise and carry your significant object. This method is used regularly to raise the load to higher, and higher.
