Pressure Test Throughput at 98% test bench availability: a worked example

Push test bench availability up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use this when planning test bench capacity for hydrostatic shell or seat tests, confirming you can meet production demand without adding overtime or a second bench.

The inputs for this scenario

  • Valves tested per cycle: 2 valves / cycle (unchanged)
  • Test cycles available per shift: 24 cycles / shift (unchanged)
  • Test bench availability: 98 % (raised for this scenario; the documented default is 85)
  • First-pass test yield: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross throughput = valves per cycle x cycles per shift) to the inputs above produces each figure below.
  • At this operating point the engine returns 44.69 valves for effective valves tested per shift (passed), the number this scenario is built around.
  • At this operating point the engine returns 48 valves for gross valve test throughput per shift.
  • At this operating point the engine returns 0.96 valves for valves lost to bench downtime.
  • At this operating point the engine returns 2.35 valves for valves lost to first-test failures.

How this compares with the baseline

  • Against the tool's baseline example, where test bench availability sits at 85% and the headline result is 38.76 valves, this scenario comes in 15.29% above the baseline at 44.69 valves.
  • It computes effective valves passed per shift by multiplying gross throughput (valves per cycle times cycles per shift) by bench availability and first-pass yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Effective valves tested per shift (passed): 44.69 valves (headline result)
  • Gross valve test throughput per shift: 48 valves
  • Valves lost to bench downtime: 0.96 valves
  • Valves lost to first-test failures: 2.35 valves
