目前有好几种试验压力渗漏的方法,其中一个普通的方法是用空气对试验的元件加压,并将其浸入水中检查气泡;另一种方法是用空气对试验的元件加压,然后关掉压力并测量可能由渗漏所造成的任何压力衰减。这个压力的衰减人们可以通过观测压力表或观测压力变送器的输出来进行测量。然而,对压力表或变送器来说,细小渗漏的输出变化可能只是试验压力的一个很小百分数。本文所概述的方法能大大地提高灵敏度,能更迅速、更可靠地检测出细小的渗漏。该装置需要用一个基准容器和一个试验容器,并要 There are several ways to test for pressure leaks. One of the common methods is to pressurize the components under test with air and immerse them in water to check for air bubbles; the other is to pressurize the components under test with air and then Turn off the pressure and measure any pressure decay that may have been caused by the leak. This pressure reduction can be measured by observing the pressure gauge or observing the output of the pressure transmitter. However, for pressure gauges or transmitters, the change in the output of a fine leak may only be a small percentage of the test pressure. The method outlined in this article can greatly increase the sensitivity and detect small leaks more quickly and reliably. The device requires a reference container and a test container, and also
