# Hydraulic press: characteristics, types, uses

A hydraulic press is a machine capable of using a great deal of less force. It is guided by the paschal principle.

This press is commonly used in various sectors, such as automotive, and has been the most used in the world for over 30 years due to its efficiency and speed in carrying out the work.

This instrument is very similar to the lever, as both generate a force greater than that exerted, but reduce the duration and speed of the journey covered.

It is a very useful tool in heavy and complicated engineering work.

## Hydraulic Press Features

The hydraulic press mainly consists of communicating vessels. These vessels are actuated by several pistons, which, due to smaller forces, allow the instrument to generate a force much greater than the initial one.

As the name implies, the hydraulic press uses water pistons (hydraulic pistons).

It is very important to keep the hydraulic presses in excellent condition and check that the hoses are in good condition to avoid any type of accident. Their maintenance is very important.

An advantage of this tool, in addition to the force generated, is that it is very safe. Also, the noise produced is minimal compared to other types of printers.

On the other hand, we can find several disadvantages, one of them is the fact that they are not as fast as a mechanical press could be.

## Types of hydraulic presses

There are many types of hydraulic presses and they vary in use and size. They can be divided into:

• manual hydraulic presses
• hydraulic foot presses
• Motorized hydraulic presses
• Bench Hydraulic Presses
• 100 ton hydraulic presses
• 200 ton hydraulic presses

## The hydraulic press and Pascal’s studios

Blaise Pascal (1623-1662) was a French physicist, mathematician, and writer whose contributions to science were of great popularity and weight.

Thanks to his scientific studies in the world of physics, Pascal’s Law was born. It sums up the statement that any pressure exerted on a liquid or fluid will spread evenly throughout the substance.

A clear example of Pascal’s principle can be seen by hydraulic presses. In them, a lesser force is exerted on the water pistons to generate a greater force.

## Uses

Hydraulic presses can be very useful, especially in companies where heavy work is done, such as the automotive or aeronautical industry, because they allow the mass production of any product through this process.

This tool not only serves in the process of assembling parts, but also works to extract them easily.

As far as the automotive industries are concerned, hydraulic presses specifically serve to mount shock absorbers, form diaphragms or hold brakes.

This tool of strength can also be found in the food industry, in the creation of pottery, in the construction of airplanes, and even in the creation of military weapons.
