The conducting systems - Part II: hydraulic hoses and fittings

摘要

As we indicated in the first part of this discussion (see April 2002, Diesel Progress), the conducting system - how hydraulic fluid moves between pumps, motors, actuators, etc. - is a critical part of any hydraulic circuit. Looking at mobile hydraulic applications, it is generally the case that piping and tubing are rigid conductors and are not suitable, since the two ends of a conductor typically move relative to one another. In such applications, flexible conductors such as hoses are used. There are more hoses to choose from than pipe or tubing. They come in many types and are designed for a broad spectrum of uses. In a hydraulic system, flexible conductors are called hose assemblies. An assembly includes a length of flexible hose to each end of which an appropriate fitting his been attached.
