rminology
cSt
A centistoke (cSt) is a measurement of kinematic viscosity. Water has a viscosity of 1 centistoke
or 1 mm
2 /second.
cut-pressure mode
High-pressure water from the intensifier that is at cutting pressure. Refer to
piece-pressure mode
.
CUTTING WATER IN
(low-pressure water)
Low-pressure water from a water softener, a reverse osmosis system, a well, or a public utility, that is
between the utility panel and the intensifier (refer to
prefilter water
and
postfilter water
)
CUTTING WATER OUT
(high-pressure water)
Water that has been pressurized by the intensifier for piercing or cutting
dB(A)
A-weighted decibels (dB(A)) is an expression of the relative loudness of sounds in air as perceived by the
human ear
dynamic seal
The high-pressure seal in the high-pressure cylinder that is nearest to the hydraulic center section. This seal
is in direct contact with the plunger (refer to
static seal
).
energy-isolating device
A mechanical device that physically prevents the transmission or release of energy, including but not limited
to the following: a manually operated electrical circuit breaker, a disconnect switch, a manually operated
switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors, a
line valve, and any similar device used to block or isolate energy. Push buttons (like the
EMERGENCY STOP
button), selector switches, and other control circuit-type devices are not energy-isolating devices.
energy source
Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy
fitting
A coupling, valve, or gauge that stops, regulates, or directs the flow of water in a pipe
hard water
Water with dissolved minerals in it, typically calcium and magnesium
high-pressure water (
CUTTING WATER OUT
)
Water that has been pressurized by the intensifier for piercing or cutting
hose
A flexible hollow cylinder. Dimensions are based on the inside diameter (ID).
inrush current
The maximum instantaneous current that a motor draws when it is first turned on, also called input surge
current or switch-on surge
ISO
The International Organization for Standardization (ISO), an independent membership organization that
develops voluntary standards
