Abstract:
Designers of mobile and off-highway equipment are developing more efficient systems to meet the demands of increased competition. Improving designs often includes a review of the hydraulic system, as engineers seek more efficient means of transmitting power. Increasingly, the focus is on reducing the size of hydraulic components or concentrating power in smaller package sizes. This can be accomplished by using higher operating pressures.To meet this challenge, developers of new off-highway hydraulic components must be able to test under those more demanding high pressure conditions. Fortunately, there are now more test-stand components available to support these manufacturers, as they design and qualify their products for higher operating pressures.Component testing is currently being conducted at pressures as high as 15 000 psi (1040 bar). As this trend toward higher pressures continues, component manufacturers will need durable high-pressure test systems to qualify products to meet the requirements of future mobile equipment.THE PURPOSE OF THIS PAPER is to review some of the high pressure hydraulic components currently available for use on test-stands. The paper will describe some existing test systems being used in the mobile equipment industry. These types of test-stands will increasingly be essential to qualify mobile hydraulic component suppliers' products for higher pressure ratings.
