1.4.2 Safety Procedures
Safety procedures must be observed while working on the pump, or any high
pressure part of the installation.
Service should only be performed by
qualified personnel.
•
The high pressure water, 4,136 bar (60,000 psi) in waterjet cutting systems
should not be a cause for concern. Users must have due respect for these
pressures and use proper SAFETY PROCEDURES and SAFE WORK HABITS.
•
Everyone associated with the waterjet cutting system must realize that the
force of the waterjet cutting stream can penetrate many dense or strong
materials.
•
Keep all untrained people away from the waterjet cutting area. Use barriers
or partitions if needed.
•
Safety glasses must be worn at all times in the waterjet cutting area.
•
All EMERGENCY STOP buttons must be checked periodically. The normal
operating position is pulled out.
•
To check: turn on power and activate the EMERGENCY STOP buttons by
pushing them in to see if the power goes off. Each device should be checked
on a specified schedule. Each time the device is checked, it must function or
be replaced before operating the system.
•
Apply High Purity Goop (P/N 10084440) to all threaded high pressure
connections. All tubing, fittings and bolted connections should be torqued to
recommended values. Do NOT attempt to tighten or loosen a HP water fitting
when the circuit is pressurized, see High Pressure (HP) Piping Safety.
•
All high pressure leaks must be repaired immediately.
•
Inspect all equipment on a scheduled basis.
•
Before performing any maintenance on the unit, MECHANICALLY LOCK
THE MAIN CONTROL POWER OFF, and assure the high pressure has been
bled off.
•
If steam or fog is noticed inside the clear top cover, this indicates a high
pressure leak. Turn off intensifier and bleed pressure before lifting the cover.
•
Pressing the emergency stop button turns off the control power to the
intensifier, stops the intensifier pump, and bleeds high pressure water
through the dump valve. Depressurization of the high pressure system can
be heard when the dump valve opens as a loud hissing that fades quickly as
the pressure drops.
