New Materials and Component Design - Key Factors for Water Hydraulic Systems 2002-01-1381
Water plays an important role in power transmission systems. The inherent cleanliness of water, combined with its long history as a power source, has pushed water back to the hydraulic forefront. Obviously, economic and environmental forces have had an impact in helping water regain its prominence as a hydraulic fluid. Today, engineers are viewing water hydraulics as an interesting technology that can offer significant advantages to solve power transmission and motion control tasks.
In order to make use of the advantage of water hydraulics the component and system design must be adapted, especially to the physical behavior of pressurized water. The materials used in the hydraulic components must have high corrosion and cavitation resistance. Poor lubricating properties requires special design of all components with moving parts, such as pumps, motors and valves.
The major aim is to discuss and high light new ideas useful for the design of water hydraulic systems. This paper especially will consider the effects of materials on the design of water hydraulic components. The water hydraulic technology have promoted advances in operation capabilities, reduced costs, increased reliability and protected the environment.
