1 – Terminology
energy-isolating device
A mechanical device that physically prevents the transmission or release of energy
Examples include a manually operated circuit breaker, a disconnect switch, or an equivalent device that
blocks or isolates energy
Selector switches, emergency stop knobs, and other circuit control devices are not energy-isolating devices.
EP
Extreme pressure, a property of some types of grease; this grease is resistant to mechanical breakdown,
oxidation, and heat
fault
The controller senses a condition that will cause a serious problem, a failure, or a possible failure condition
fitting
A coupling, a valve, or a gauge that stops, regulates, or controls the flow of water in a pipe
FLA
Full-load amperes (current)
ft∙lbf
Foot-pound force, a unit that identifies the work or energy transferred when applying a force of 1 pound to
an object through a distance of 1 foot: 1 ft∙lbf equals 1.36 N∙m or 1.36 joules
Refer to .
joule
gate valve
Also known as a sluice valve, a knife valve, or a slide valve; controls the flow of liquid through a pipe
hard water
Water with dissolved minerals in it, usually calcium and magnesium
HEPA filter
High-efficiency particulate air filter, a mechanical air filter that catches particles that are 0.3 microns in
diameter (1 micron = 1 millionth of a meter) or larger
The US National Institute for Occupational Safety and Health grades HEPA filters based on resistance to
degradation from oil and level of efficiency (95%, 99%, and 99.97%).
high-pressure water (C
UTTING WATER OUT
Low-pressure supply water goes into the intensifier, where it is pressurized for piercing and cutting
hopper
A container that is wider at the top than at the bottom
hose
A flexible, hollow cylinder that is used to move low-pressure fluids; hoses typically have quick-disconnect
fittings
Hose is sized by its inside diameter (ID).
Refer to pipe, tube, and tubing.
ID
Inner diameter, the diameter of the inside of a cylinder
