压力衰减测试系统

压力衰减泄漏测试是当今最常用的。它的简单性使其易于自动化并集成到生产/组装过程中。

用最简单的话来说，压力衰减测试将压力容器充满了空气，直到达到目标压力，切割空气源以隔离压力，并在设定的时间内测量该压力的衰减（损失）；压力的任何损失都表示泄漏。压力衰减方法的敏感性是测试零件大小和测试时间的函数。大多数测试可以相当快地进行，并具有高度准确的结果，但是零件越大，获得准确的测试结果所需的循环时间越长。

Benefits of Pressure Decay Leak Testing

  • Sensitive enough to detect very small leaks
  • Can test in pressure or vacuum environments
  • 根据压力或真空确定泄漏率
  • 可以校准体积流量
  • Can report pressure or flow loss (psig or scc/min)
  • Provides a simple and highly effective leak test method

精准医疗ssure Decay Leak Test Accuracy


In most instances, the smallest pressure change that can be detected via pressure decay test is 0.1 Pa/0.001 mbar/0.0000145 psi. Temperature variations can affect accuracy.

精准医疗ssure change is directly proportional to leak rate; pressure change can be converted to leak rate if the internal volume of the test article is known, the pressure change is measured accurately, and the duration of the test is recorded. The following equation can be used to convert pressure change to leak rate:
LRsccm=V × (dP测量– dPno-leak) ×60秒/分钟
T×patm

LR= leak rate (scc/s)
dP测量=pressure loss measured during testing cycle (psig)
dPno-leak= pressure loss for a non-leaking part measured during test time (psig)
V= volume (cm3)
T= time (seconds)
Patm=standard atmospheric pressure (psig)
Formula derived from Ideal Gas Law.
