Download or read book Functional safety of machine controls written by Hauke, M. and published by DGUV/IFA. This book was released on 2019-08-20 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this information, the report can be used to select the required Performance Level PLr for safety functions in control systems. The Performance Level PL which is actually attained is explained in detail. The requirements for attainment of the relevant Performance Level and its associated Categories, component reliability, levels of diagnostic coverage, software safety and measures for the prevention of systematic and common-cause failures are all discussed comprehensively. Background information is also provided on implementation of the requirements in real-case control systems. Numerous example circuits show, down to component level, how Performance Levels a to e can be engineered in the selected technologies with Categories B to 4. The examples provide information on the safety principles employed and on components with well-tried safety functionality. Numerous literature references permit closer study of the examples provided. The report shows how the requirements of EN ISO 13849-1 can be implemented in engineering practice, and thus makes a contribution to consistent application and interpretation of the standard at national and international level.

Book excerpt: Most of the existing books in this field discuss the hydraulic and pneumatic systems in concentrating on the design and components of the system without going deep enough into the problem of dynamic modelling and control of these systems. This book attempts to compromise between theoretical modelling and practical understanding of fluid power systems by using modern control theory based on implementing Newton's second law in second order differential equations transformed into direct relationships between inputs and outputs via transfer functions or state space approach.

Download or read book Hydraulics and Pneumatics written by Andrew Parr and published by Elsevier. This book was released on 2013-10-22 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulics and Pneumatics: A Technician's and Engineer's Guide provides an introduction to the components and operation of a hydraulic or pneumatic system. This book discusses the main advantages and disadvantages of pneumatic or hydraulic systems. Organized into eight chapters, this book begins with an overview of industrial prime movers. This text then examines the three different types of positive displacement pump used in hydraulic systems, namely, gear pumps, vane pumps, and piston pumps. Other chapters consider the pressure in a hydraulic system, which can be quickly and easily controlled by devices such as unloading and pressure regulating valves. This book discusses as well the importance of control valves in pneumatic and hydraulic systems to regulate and direct the flow of fluid from compressor or pump to the various load devices. The final chapter deals with the safe-working practices of the systems. This book is a valuable resource for process control engineers.

Download or read book CONTROL VALVE TEST PROCEDURE written by CTTC C1, Hydraulic Systems and published by . This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: aFlow versus pressure drop bLeakage rate cOperating effort dMetering characteristics versus spool travel, pilot pressure, or electrical current eRelief valve characteristicsThe document applies to single and multiple section hydraulic directional control valves.This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure.NOTEPerformance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests. In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. The hydraulic fluid power control valve is used to direct and control the fluid in the circuit to achieve the desired functions and flow of the fluid.The pressure drop, leakage rate, operating effort, metering characteristics and relief valve characteristics are indications of the ability of the control valve to perform the desired functions.The test procedure has been a recommended practice since 1956, last revised in 1975 and a five year review was started in 1982. Since several documents have been written which describe certain tests in more detail, they have been incorporated into this procedure. Also, the wording has been revised to expand the scope of the procedure to include other input forms in addition to direct manual operation.After a number of rewrites and input from manufacturers and end users, the revised test procedure was balloted in ORMTC SC4 on July 16, 1987, with fifteen approvals, one disapproval, and seven no replies. The subcommittee also recommended to upgrade the document to a standard and to submit the document to ANSI. The document has been revised to resolve the disapproval and include revisions from comments on the approval ballots.
