| Barker/Diacon engineers
were among the first to introduce this technology to the utility industry in
1982. From those beginnings comes the Barker/Diacon IPST10 Snubber Test
System. The IPST10 provides a method of testing large bore hydraulic
snubbers in their installed locations. Full functional testing of the
snubber valves, through lockup and bleed rate testing, and of the snubber
pressure seals can be accomplished. Tests are directly comparable with those
performed on a test bench. To use the IPST10,
the test machine is moved to the location of the snubber via supplied quick
connect fittings. Fifty feet of hose are supplied to attach the machine to
the snubber. The snubber may be left attached to the plant structure, if
suitable manifolds have been installed, or one or both pins may be removed.
All tests are carried out via computer control from the test machine, which
is an ALARA benefit.
The IPST10 simulates bench testing by calculating
the internal snubber pressure and flow which correspond to requested snubber
loads and velocities. These calculated values are then applied to the
snubber and the results measure with the use of precision pressure and flow
transducers.
The results are correlated back to the more common units of force and
linear velocity for output to color graphic printout. |
