Document Summary
Total of 25 out of 100 points for questions #1 to #6. 12/12/07: [6] name the three broad classifications of fluid power (pneumatics and hydraulics) valves. Sketch a schematic of a specific valve for each category. _________________________________ valves sketch: [3] name each of these mechanical limit switch contact configurations: Over: [5] one way that hydraulic components are commonly connected or plumbed is by using pipe. Set @ 2000 psi dpiston=1. 50 in drod=0. 75 in: estimate the pressures p1, p2, and p3 when the load stops at the maximum height against the barrier. P3 : [15] a complete pneumatic and ladder logic system is shown below. Fully describe the operation of this system both in terms of ladder logic components (c1, y2, x10, etc. ) and in terms of the actions of the two cylinders. K4: [40] a local manufacturer has a need for a pneumatic system controlled by a plc.
