Hi All,
I have a project right now that involves monitoring for failures within a landing gear control system. We have solenoid operated valves that at times fail at the energizing coil and I would like to detect these failures. We have a control box that is capable of monitoring (so I'm...
I have a general question regarding built in testing / failure sensing for electronic components. I realized I lacked this knowledge when reviewing an old failure report as I started wondering how failures are sensed. I'd like to do some research on this topic so that I understand the concepts...
Hi,
I'm looking to calculate the required cable tension in a closed loop installation (two quadrants with cable wrapped around both). One of the quadrants is connected to a handle for activation, the other quadrant is connected to the rest of the system.
What are the guidelines for...
Does anyone have literate on fluorocarbon seals? I received a vendor analysis report that found fluorine and carbon in the system filters. What fluids are compatible with fluorocarbon seals? Is AS 1241 Synthetic Phosphate Ester compatible
I did a quick Google search for fluorocarbon seals...
I've been trying to find why reversing the polarity in DC circuits is (except with 'special' devices) harmful. I haven't been able to find anything doing some Google searches, which leads me to believe the reason is so simple and straight forward that explanations are avoided and instead people...
Hi all,
I have a pump right now that at times is not priming properly on start up, which I theorize is happening because of low inlet pressure.
The line inlet is 3/8" diameter and the pump is an axial piston type producing about .6 GPM flow (or less). The reservoir is about one foot above the...
I'm trying to determine how long it would take for a hydraulic accumulator to bleed down from full working pressure to empty (no fluid remaining).
The equation that I have been using is Q = C*(deltaP)^(1/2). In order to determine the constant C, I'm using the initial conditions for Q (leakage...
I started working as a hydraulic systems integrator ~1.5 years ago and would like some good reference books. I've been looking around and I have heard that 'Hydraulic System Analysis' by George Keller is really good.
I Google'd around for some stuff one day and came upon 'Handbook of Hydraulic...
