Study Notes
Pressure Gauge Protection
- Utilize a snubber to protect pressure gauges from surges.
Hydraulic Line Construction
- Avoid using galvanized pipe for hydraulic lines.
Bypass Line Purpose
- Bypass lines around system filters facilitate flow during emergencies.
Force Calculation in Cylinders
- A cylinder with 50 psi input pressure and a 5 sq. inch piston area produces 250 lbs of force.
Oil Filter Screen Pressure Drop
- A 40% pressure drop across an oil filter indicates a dirty screen.
Fluid Reservoir Function
- An air-breather is essential for venting fluid reservoirs.
Piston Surface Area in Cylinders
- Single-rod, double-acting pistons have unequal surface areas.
Directional Flow Valve
- Check valves permit flow in only one direction.
Fluid Pressure Distribution
- Fluid pressure is distributed equally throughout the fluid.
Air-Operated Pump Behavior
- Shutting off the discharge of a reciprocating pump can cause it to overstroke.
Hydraulic vs. Pneumatic Cylinders
- Hydraulic cylinders necessitate return lines, unlike pneumatic cylinders.
Meeting Hydraulic System Demands
- Accumulators help manage peak hydraulic system demands.
Four-Way Valve Exhaust
- Exhaust air from a four-way valve is directed to the atmosphere.
Pneumatic System Troubleshooting
- Prioritize checking the air supply when troubleshooting pneumatic systems.
Piston Speed Determinants
- Piston speed relies on the amount of metered outlet air.
Air Motor Operating Speed
- Safe operating speed for air motors is controlled by load.
Air Lubricator Installation
- Install air lubricators after regulators in pneumatic systems.
Post Heating Welded Metals
- Post-heating increases ductility in welded metals.
Oxygen Cylinder Valve Operation
- Fully turn the diaphragm screw out before opening the tank valve on an oxygen cylinder.
Brazing Advantage
- Brazing allows joining dissimilar metals, unlike welding.
Welding with Metallic Electrodes
- Use electrodes with alloys similar to those of the base metal for steel alloys.
