Power transmission
The same pressure applies at every point in a closed system. For this reason, the shape of the container has no significance. Where a container is formed as shown in the diagram, it is possible to transmit forces. The fluid … Continue reading
Pressure transmission
If a force FT1T acts via an area AT1T on an enclosed liquid, a pressure p is produced which extends throughout the whole of the liquid (Pascal’s Law). The same pressure applies at every point of the closed system (see … Continue reading
Hydraulic Force, Area
Every body exerts a specific pressure p on its base. The value of this pressure is dependent on the force due to weight F of the body and on the size of the area A on which the force due … Continue reading
Hydraulic pressure
Hydraulics is the science of forces and movements transmitted by means of liquids. It belongs alongside hydro-mechanics. A distinction is made between hydrostatics – dynamic effect through pressure times area – and hydrodynamics – dynamic effect through mass times acceleration. … Continue reading
Comparison of hydraulics with other control media
There are other technologies besides hydraulics which can be used in the context of control technology for generating forces, movements and signals: • Mechanics • Electricity • Pneumatics It is important to remember here that each technology has its own … Continue reading
Mobile hydraulics
Typical application fields for mobile hydraulics include: • Construction machinery • Tippers, excavators, elevating platforms • Lifting and conveying devices • Agricultural machinery There is a wide variety of applications for hydraulics in the construction machinery industry. On an excavator, … Continue reading
Stationary Hydraulics
The following application areas are important for stationary hydraulics: • Production and assembly machines of all types • Transfer lines • Lifting and conveying devices • Presses • Injection moulding machines • Rolling lines • Lifts Machine tool construction is … Continue reading
What do we mean by hydraulics?
Hydraulic systems are used in modern production plants and manufacturing installations. By hydraulics, we mean the generation of forces and motion using hydraulic fluids. The hydraulic fluids represent the medium for power transmission. The object of this book is to … Continue reading
Hydraulics Pneumatics Pressure regulation
Figure 2.5a shows the by now familiar system where a load is raised or lowered by a hydraulic cylinder. With valve V1 open, fluid flows from the pump to the cylinder, with both pressure gauges P1 and P2 indicating a … Continue reading
