5.8 System Leak Test & Function Test
NOTE:
These tests are performed as part of the process detailed in section 5.7 and need not be repeated
if the full process described in section 5.7 has been performed.
Low-Pressure Leak Test & Function Test
IMPORTANT:
A system leak test should be performed each time a coupler/s is disconnected and new
connections are made. Paying special attention to connection points and new components
introduced to the system. (Hoses, tools etc.)
With all hoses and tools correctly connected to the pump and the pump connected to the power supply,
perform a low-pressure leak test.
Make sure the pressure relief valve (11) is in its fully open position (wound anti-clockwise).
Turn the Pump ‘ON’ by pressing the ‘Advance button’ on the control pendant (18) once.
Press and hold the ‘Advance Button’ on the control pendant. (At this stage the pressure gauge
should read zero and the connected tool should not advance).
While holding the ‘advance button’ in, slowly turn the pressure relief knob clockwise and monitor the
pressure gauge. The pressure will slowly start to build and the torque wrench will begin to advance.
Continue until the gauge reads approximately 100 bar.
With the pressure holding steady around 100 bar, perform a visual inspection of the tool/s, hoses
and couplers for any signs of oil leakage.
DO NOT
touch the hoses or couplers while the system is pressurised.
o
If a leak/s is found, depressurise the system completely before attempting to repair, resolve
or inspect a leaking component.
DO NOT
wipe away excess oil from any component while
the system is still pressurised.
o
If no leaks are found during the leak test it is safe to continue.
High-Pressure Leak Test
With the leak test completed and before connecting the tool to a nut/bolt, perform a function test to ensure
the tool and pump operate correctly through their entire pressure range.
A function test should be performed at the beginning of each work shift and should be repeated for every
new tool connected to the pump, during the shift.
While continuing to hold the pump in advance mode, adjust the pressure relief valve (clockwise)
until the pressure gauge reads 700 bar.
Cycle the pump 2-3 times to full pressure making sure both the pump and connected tool/s operate
smoothly through the entire pressure range.
Visually inspect the system for leaks.
If any issues are found during the function test, they must be investigated and resolved before putting the
pump / tool into use.
