Portable Hydraulic Power Source

摘要

A portable Hydraulic Power Source (PHPS) has been designed to enable the NavalConstruction Divers to operate oil hydraulic tools in an Arctic environment. The PHPS is a three-piece assembly developed to be lightweight, mobile, and capable of powering hydraulic tools through a 250-foot hose. It can be handled manually by four personnel, transported in a small aircraft, and operated from a 22-foot inflatable boat. The PHPS can start at -40 F and supply 8 gpm of hydraulic fluid at 2,000 psi. This report describes the system, the approach used in developing the system, and the results of performance and reliability testing.
