Contamination in Fluid Power Systems


Book Description




Hydraulic Systems Volume 3


Book Description

This book is the third in its series. The book overviews various types of hydraulic fluids, their physical properties and the standard methods to test them. The book also covers standard methods to evaluate and control various types of hydraulic fluids contamination.




Assessing Cleanliness of Hydraulic Fluid Power Components and Systems


Book Description

To describe laboratory methods for determining and reporting the contaminant level of the wetted portion of hydraulic fluid power components, parts, subsystems and systems, and of fill fluids. For each type of item it provides a method of obtaining the liquid sample and the contamination level thereof. It also includes procedures for establishing a sampling plan and guidelines for establishing levels of acceptance, but does not set those levels. To provide a basis for measuring and reporting cleanliness levels so that built-in contamination and premature failures of hydraulic systems can minimized.




Principles of Hydraulic Systems Design, Second Edition


Book Description

Fluid power systems are manufactured by many organizations for a very wide range of applications, embodying different arrangements of components to fulfill a given task. Hydraulic components are manufactured to provide the control functions required for the operation of a wide range of systems and applications. This second edition is structured to give an understanding of: • Basic types of components, their operational principles and the estimation of their performance in a variety of applications. • A resume of the flow processes that occur in hydraulic components. • A review of the modeling process for the efficiency of pumps and motors. This new edition also includes a complete analysis for estimating the mechanical loss in a typical hydraulic motor; how circuits can be arranged using available components to provide a range of functional system outputs, including the analysis and design of closed loop control systems and some applications; a description of the use of international standards in the design and management of hydraulic systems; and extensive analysis of hydraulic circuits for different types of hydrostatic power transmission systems and their application.

Requirements for an Effective Program in Fluid Contamination Control


Book Description

Contamination control in a hydraulic system means that the filtration equipment of a system has established a fluid contamination level which is within the contaminant tolerance specifications of the hydraulic components. Such a control condition is not beyond the realm of practicality and must be achieved if hydraulic systems are to function in an optimal manner. Sufficient technology has been developed to permit the specification of the requirements for achieving, maintaining, and appraising contamination control conditions.
