Download Slurry Transport Using Centrifugal Pumps by K. C. Wilson, G. R. Addie, A. Sellgren, R. Clift PDF

By K. C. Wilson, G. R. Addie, A. Sellgren, R. Clift

Gigantic tonnages of solid-liquid combinations are pumped each year in dredging operations, mining and waste-disposal purposes. each one of these platforms are centrifugal pumps, and the answer of difficulties encountered in slurry pumping calls for either particular medical wisdom and judgment derived from useful adventure.   for a few years the mix of up to date research and hands-on experimentation has been supplied to engineers in a brief direction dependent on the GIW Hydraulic Laboratory. the teachers during this path, who signify a large heritage of foreign services, have ready this widely-recognized textual content, Slurry shipping utilizing Centrifugal Pumps, 3rd variation.   This targeted textual content is logically divided into sections: the 1st a part of the publication concentrates at the behaviors of varied varieties of slurry circulate, and the second one half bargains with the habit of centrifugal pumps dealing with slurries, and with how pumps and pipelines engage as a method.   Slurry shipping utilizing Centrifugal Pumps, 3rd variation additionally contains: New fabric on either non-Newtonian flows and slurries of granular debris. New info on pump put on, solids impact, and method operation. up-to-date and fully new fabric on pump choice and environmental points labored examples and case reviews that tension useful functions Slurry shipping utilizing Centrifugal Pumps, 3rd variation, may be of curiosity to all engineers and technologists taken with the large-scale transportation of slurries. .

Download PID Controller Tuning Using the Magnitude Optimum Criterion by Konstantinos G. Papadopoulos PDF

By Konstantinos G. Papadopoulos

An instructive reference that would support regulate researchers and engineers, attracted to quite a few business tactics, to exploit a robust tuning strategy for the ever-popular PID regulate paradigm.

This monograph provides specific PID tuning ideas for linear keep watch over loops despite procedure complexity. It exhibits the reader how such loops in achieving 0 steady-position, speed, and acceleration blunders and are therefore in a position to music quick reference indications. The theoretical improvement happens within the frequency area by means of introducing a general-transfer-function-known technique version and by means of exploiting the primary of the significance optimal criterion. it really is paralleled by means of the presentation of actual business regulate loops utilized in electrical motor drives. the appliance of the proposed tuning principles to a wide classification of approaches exhibits that regardless of the complexity of the managed strategy the form of the step and frequency reaction of the regulate loop shows a particular functionality. This particular functionality, besides the PID specific resolution, formulates the foundation for constructing an automated tuning process for the PID controller parameters that is an issue frequently met in lots of applications—temperature, pH, and humidity keep an eye on, ratio regulate in product mixing, and boiler-drum point regulate, for instance. the method of the version is taken into account unknown and controller parameters are tuned immediately such that the aforementioned functionality is accomplished. the aptitude either for the specific tuning principles and the automated tuning procedure is established utilizing numerous examples for benchmark approach types routine often in lots of applications.

Download Elasto-Hydrodynamic Lubrication: International Series on by D. Dowson PDF

By D. Dowson

Elasto-Hydrodynamic Lubrication bargains with the mechanism of elasto-hydrodynamic lubrication, that's, the lubrication regime in operation over the small parts the place computing device elements are in nominal element or line touch. The lubrication of inflexible contacts is mentioned, in addition to the consequences of excessive strain at the lubricant and bounding solids. The governing equations for the answer of elasto-hydrodynamic difficulties are presented.

Comprised of thirteen chapters, this quantity starts with an summary of elasto-hydrodynamic lubrication and illustration of contacts by way of cylinders, by way of a dialogue on equations suitable to lubrication, together with the Reynolds equation. The reader is then brought to lubrication of inflexible cylinders; the significance of movie thickness in hugely loaded inflexible contacts; the pliancy of solids involved; and the speculation of elasto-hydrodynamic lubrication. next chapters specialise in equipment and measurements of movie thickness and picture form; friction and viscosity; and lubrication of gears and curler bearings.

This ebook could be of curiosity to tribologists.
