高效过滤器检漏

犁跃

在洁净区空调系统验证时，有一项高效过滤器检漏是否用悬浮粒子计数器检测，测试方法：尘埃粒子计数扫描巡检法。

1.测试范围：

a) 过滤器的滤材。

b) 滤材与其框架内部的连接。

c) 过滤器框架的密封和过滤器组支撑框架之间的连接。

d) 支撑框架和墙壁或顶棚之间的连接。

2.检测仪器：尘埃粒子计数器。

3.接受标准：测得的悬浮粒子数不得出现突然变大现象检测标准是

你们是否有更好的方法？谢谢！

现在主流 PAO检漏

The purpose of performing regularly scheduled leak tests, on the other hand, is to detect leaks from the filter media, filter frame, or seal. The challenge involves use of a polydispersed aerosol usually composed of particles with a light-scattering mean droplet diameter in the submicron size range,9 including a sufficient number of particles at approximately 0.3 μm. Performing a leak test without introducing a sufficient upstream challenge of particles of known size upstream of the filter is ineffective for detecting leaks. It is important to introduce an aerosol upstream of the filter in a concentration that is appropriate for the accuracy of the aerosol photometer. The leak test should be done in place, and the filter face scanned on the downstream side with an appropriate photometer probe, at a sampling rate of at least one cubic foot per minute. The downstream leakage measured by the probe should then be calculated as a percent of the upstream challenge. An appropriate scan should be conducted on the entire filter face and frame, at a position about one to two inches from the face of the filter.

PAO检漏，，也就是烟雾。。仪器挺贵的，，凑活着用你的尘埃粒子检测仪吧。

换个角度，找在线翻译啊
另一方面，执行定期排定的泄漏测试的目的是检测来自过滤介质、过滤框架或密封的泄漏。该挑战涉及使用一种通常由在亚微米尺寸范围内具有散射平均液滴直径的粒子组成的多散性气溶胶，9其中包括在大约0.3微米处的足够数量的粒子。在没有引入足够的上游挑战的情况下，对过滤器上游已知尺寸的粒子进行泄漏测试。

洁净区高效安装的设计是新的吗，还是老厂房，有的高效没有通PAO烟雾的注入口和检测口，只能用尘埃粒子计数器扫描法，如果有注入口和检测口，还是用PAO的好，准确

目前设计的送风口、层流罩 都有发尘和检测口，配合PAO发尘检测仪捡漏。

pao检漏的标准是多少？

估计没有PAO检测口啥的
