What is HEPA filter leak detection? Is there any way?
What is HEPA filter leak detection? Is there any way?From the filtration efficiency of the high-efficiency filter, we know that the environment in which it is used will have higher requirements for air quality. So during the use of the high-efficiency filter, does it work normally, and how does it detect and avoid leaks in time? This requires users to regularly check for leaks in the high-efficiency air filter. So, what are the leak detection principles and methods of high-efficiency air filters?Leak detection principle of high-efficiency air filter: The principle of high-efficiency filter leak detection is to use the aerosol generated at the upper air outlet of the filter to be detected as a dust source. Sampling can be carried out at the lower air outlet through a photometer. At this time, the gas containing dust will pass through the electrical effect and the scattered light emitted by the photometer. Linear amplification is converted into electrical power, which is then quickly displayed by a microammeter; when detecting equipment leaks, different leak detection methods can be selected according to different environmental requirements, which can reduce production costs and increase work efficiency. Leak detection method of high-efficiency air filter: In the production process of some medical devices in our country, the requirements for the production environment are very strict, because the environment will directly affect the quality of the products, so these companies will pay attention to the cleanliness of the air when building factories, as well as the dust particles and particles in the air in the factory. The number of microorganisms; in today's pharmaceutical and medical device production industries, many use air filters to introduce outdoor air into the room. The air enters the factory after being filtered, which can effectively ensure the quality of the air in the production environment. |
