Application of New Materials in Water Hydraulic Pump

Abstract

In water hydraulic piston pump, poor lubrication is more likely to happen than in oil hydraulic one because of difference in properties between water and oil. So there are some key problems such as corrosive wear and erosion, which are investigated briefly in this paper. Many new materials have been developed, which give longer life expectancies with water without corrosion and erosion. Recently, a new type of water hydraulic piston pumps with better suction characteristics had been developed. Much of this research has concentrated on new materials, structure and experiments, which are also specially introduced in this paper.
