Basic hydraulic knowledge

Hydraulic pump station is a device that uses liquid to transfer pressure. When the liquid transmits pressure in a closed container, it follows Pascal's law.. Hydraulic pump station

Nowadays, hydraulic system is widely used in construction machinery. Although there are electrical, pneumatic or mechanical systems to choose from, hydraulic systems have been increasingly used. For example, on many excavators, the hydraulic system is used to lift and lower the boom, move the bucket, and complete the swing action of the upper structure of the machine.

Why use hydraulic system? There are many reasons, partly because the hydraulic pump station has the characteristics of wide use, high efficiency and simplicity in power transmission. The task of the hydraulic pump station is to change the power from one form to another. We hope this book can help you understand the basic working principle of hydraulic system. The history of hydrostatic hydraulic development of fluid power bodies We have said that hydraulic systems transform power from one form to another. This process is accomplished by using a closed liquid as a medium. The science of transferring force or motion through closed liquid processing is called "hydraulics". The word hydraulics comes from the Greek word "hydros", which means water. Hydraulic science is a young science - only hundreds of years old. It began with the hydraulic lever transmission principle discovered by a man named Blaise Pascal. This principle was later called Pascal's law. Although Pascal made this discovery, it was another man named Joseph Bram who made the hydraulic press in 1795 for the first time. The liquid used as the medium in this hydraulic press is water. Hydrodynamics and hydrostatics hydraulics have made great progress since Pascal's discovery. In fact, it has now been divided into two sciences. Fluid dynamics is what we call the science of moving liquids. Hydrostatics is what we call pressure fluid science. A water wheel is a good example of a hydrodynamic tool. The energy used is the motion energy of water. In hydrostatic devices, different energies are used. Liquid is used as a medium of energy. The flow of liquids produces motion, but they are not the source of such motion. As the closed liquid is under pressure, energy is transferred. Most of the hydraulic pump stations used today operate in a hydrostatic manner.
