This is kind of a jack of all trades test stand that is used for any type of system/component performance testing for hydraulic systems. The stand has two large piston pumps for high pressure testing and a screw pump that we use for high flow low pressure testing. The valve I am looking for is...
I'm looking for a relief valve that will handle 150-200 gpm and maintain a low pressure (10-20 psi or even lower if possible). Ideally the valve would have the capability of controlling the relief setting electronically (or with a pilot pressure that could be controlled electronically). The...
Thanks to both of you for your input. We do run into similar poor maintenance type failures like JohnRobinsonOz mentioned, but I wouldn't say that is the majority of our failures.
Vanstoja's comments are quite similar to what we do today, but the direct tie to machine hours isn't there. We...
I work in hydraulics in off-highway equipment. I am curious what other people in industry do to verify the durability of hydraulic pumps (piston pumps, gear pumps). Our testing leans toward "we've run this test for years and haven't had any problems in field, so if we pass it again it...
