Download or read book Proposed Hydraulic Pump Testing for Hydraulic Fluid Qualification written by HM. Melief and published by . This book was released on 1997 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current ASTM D-2882 hydraulic vane pump test does not provide the necessary correlation required for the prediction of the lubricating properties of a hydraulic fluid in various piston pump operations. All too often, a fluid will exhibit excellent wear properties in the Vickers V-104 vane pump used in the ASTM D-2882 test, yet produce catastrophic failure at various wear interfaces in a piston pump which may consist of different material pairs, contact loading, configuration or speed. In this paper, a new piston pump test, which is conducted under cycled pressure testing conditions, is proposed. The new test will provide an excellent assessment of the lubricating properties of a hydraulic fluid under a wide variety of wear conditions.

Book Synopsis The Gamma Wear Test for Hydraulic Fluid Qualifications by : DJ. Heer
Download or read book The Gamma Wear Test for Hydraulic Fluid Qualifications written by DJ. Heer and published by . This book was released on 1997 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The qualification of fluids for use in a hydraulic system has been a major concern to component manufacturers for several years. The primary issue in a hydraulic system is the compatibility of the fluid with the main pump in the system. There are several bench-type wear tests for the evaluation of fluids, however, most of these are not intended specifically for hydraulic fluids but were developed for lubrication fluids. Therefore, many engineers have relied upon the pump tests which were available in order to select the fluid to be used in their hydraulic system. The testing of a hydraulic pump to qualify a hydraulic fluid is very time consuming and expensive.

Download or read book Pump Tests for Hydraulic Fluid Wear Qualification written by DJ. Heer and published by . This book was released on 1997 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern hydraulic systems are operating at higher pressures and higher temperatures than ever before. In addition, the life and reliability of the hydraulic components and hence the hydraulic system is becoming more and more dependent upon the characteristics of the circulating fluid in the system. The hydraulic component which normally suffers most when the correct fluid is not used in the system is the hydraulic pump. Three different types of hydraulic pumps are widely used in hydraulic systems. Vane pumps have been the dominant type of pump for hydraulic systems. Gear pumps have replaced vane pumps in many applications. Piston pumps are rapidly gaining popularity. Therefore, the pump manufacturers are conducting tests to qualify fluids for use with their pumps and the fluids formulators are conducting tests to show that their formulations are compatible with hydraulic components. Unfortunately, the tests most widely used are either not industry standards or do not address problems encountered with some hydraulic pumps.

Book Synopsis Use of Bench Tests to Evaluate Water-Glycol Hydraulic Fluid Lubrication by : L. Xie
Download or read book Use of Bench Tests to Evaluate Water-Glycol Hydraulic Fluid Lubrication written by L. Xie and published by . This book was released on 2001 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anti-wear lubrication performance of a series of hydraulic fluids was determined using various bench wear tests including: Four-Ball, Pin-on-V-Block Falex Wear Test, Timken Block-on-Ring, a recently developed cyclic contact stress (3-vane-on-ring) test and the ASTM D-2882 Vickers V-104C vane pump test. These bench tests were selected since they are used in the fluid power industry for fluid selection, qualification and performance troubleshooting. The results of this work showed that none of the bench tests evaluated provided any correlation with the wear rates obtained with the ASTM D-2882 pump test. Bench wear test correlations are possible only if the conditions of the wear test, such as wear contact geometry, loading, speeds, and materials reasonably model the specific wear contact of interest in the hydraulic pump. Even then, the general reliability of the bench testing conditions should first be validated by hydraulic pump testing.

Book Synopsis Tribological Testing with Hydraulic Pumps by : RJ. Bishop
Download or read book Tribological Testing with Hydraulic Pumps written by RJ. Bishop and published by . This book was released on 1997 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fluids serve two functions in the hydraulic system; to transfer energy and to lubricate the system. The energy transfer role is relatively well understood while lubrication assessment has been hindered by inability to adequately model hydraulic systems in general by small-scale pump prototypes or by bench testing. In general, most conventional bench tests do not adequately model wear which may accompany hydraulic fluid use in various hydraulic pump designs. Therefore, this has necessitated the use of hydraulic pumps as tribological test stands. The objectives of this paper are to: 1) review common failure modes of different types of hydraulic pumps, 2) provide an overview of the deficiencies of bench testing of hydraulic fluids, 3) review the tribological criterion for successful lubrication of vane, piston and gear pump testing, 4) review the most common pump tests reported to date, and 5) critique the quality of these tests relative to their ability to provide the required data.
Book Synopsis A New Test Method for Determining the Anti-Wear Properties of Hydraulic Fluids by : PV. Cox
Download or read book A New Test Method for Determining the Anti-Wear Properties of Hydraulic Fluids written by PV. Cox and published by . This book was released on 1997 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing pump test procedures for determining the anti-wear properties of hydraulic fluids are expensive to undertake, have a long test duration and require a large quantity of test fluid. This paper describes a project to develop an alternative low cost bench screening procedure of short duration, requiring only a small quantity of test fluid and using simple reproducible test specimens. A high level of correlation is demonstrated between the new test method and existing vane pump test procedures for a range of hydraulic fluids including mineral oils and water-glycol fluids. The new test procedure is highly suited to the hydraulic fluid development process requiring only ten litres of fluid per test and a maximum total test duration of six hours.

Book Synopsis Endurance Pump Test with MIL-PRF-83282 Hydraulic Fluid, Purified with Malabar Purifier by :
Download or read book Endurance Pump Test with MIL-PRF-83282 Hydraulic Fluid, Purified with Malabar Purifier written by and published by . This book was released on 2004 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible deterioration of the fluid during use or the potential for the purifier to remove some of the performance improving additives from the fluid as well as the contaminants was investigated. Endurance aircraft hydraulic pump tests under carefully controlled conditions were previously conducted using hydraulic fluid purified with a rotating-disk and vacuum type purifier, the portable purifier manufactured by Pall Corporation, to assess the potential negative effect the fluid purifier could have on hydraulic fluid performance. In this study, similar tests were conducted with a mist and vacuum type purifier, manufactured by Malabar International. Fluid samples were taken at selected intervals during the pump tests and key physical and chemical properties were determined. Pump tests with both fresh and purified MIL-PRF-83282 hydraulic fluids were successfully completed, and there was no apparent difference in pump performance or in fluid characteristics with either fluid. The mist and vacuum type Malabar purifier is therefore similarly benign to the hydraulic fluid as are the Pall portable purifiers. These Malabar mist and vacuum type purifiers will be integrated into some new hydraulic test stands being procured by the U.S. Air Force.
