Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids.
On the basis of base oil, the hydraulic fluid market has been segmented into mineral oil, synthetic oil (PAO, PAG, Esters, and Group IV), semi-synthetic oil, and bio-based oil. The mineral oil segment is projected to lead the hydraulic fluid market during the forecast period due to its easy availability and low cost.
Hydraulics is a technology involving the mechanical properties, which operates through the force of liquid pressure. In a Hydraulic system, Hydraulic Fluid is used as an energy transfer medium. It is also useful in other applications such as heat transfer, sealing, contamination removal, corrosion resistance, and lubrication. This industry’s future growth path is determined by high demand in oil & gas, automobile, marine¸ aircraft, industrial machinery, construction, and others industries. Global Hydraulic Fluid Market is expected to witness a significant growth of USD 4,317.10 million by 2023, with CAGR of 2.57% during forecasted period.
Pneumatics is a branch of engineering that makes use of gas or pressurized air. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically powered compressor powers cylinders, air motors, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and actuators.
Pneumatics is the technology of compressed air, but in some circles, it is more fashionable to refer to it as a type of automation control. Pressurized gas—generally air that may be either of the dry or lubricated type—is used to actuate an end effector and do work. End effectors can range from the common cylinder to more application-specific devices such as grippers or air springs. Vacuum systems, also in the pneumatic realm, use vacuum generators and cups to handle delicate operations, such as lifting and moving large sheets of glass or delicate objects such as eggs.
The global pneumatic equipment market will grow moderately during the forecast period and post a CAGR of almost 5% by 2020. In addition to their applications in several industries, pneumatic tools are gradually acquiring significant application in food processing and medical applications as well.
