How to carry out leak detection test for efficient filter? How to carry out leak detection test for efficient filter?People and purification are introduced to you.Determine whether there is a clear leakage in the efficient filter itself and its installation,The following must be tested on site: filter material of the filter;The connection between the filter material of the filter and the inside of its frame;Between the seal pad of the filter frame and the filter group support frame;Between the support frame and the wall or ceiling.There are two kinds of testing instruments,One is the aerosol spectrometer,The other is the particle counter,The commonly used detection instrument in high-efficiency filter leak detection is the aerosol spectrometer (hereinafter referred to as the spectrometer ),It is a linear spectrometer with front scattering,It consists of vacuum pump, light scattering chamber, photoelectric multiplier tube, signal processing converter and microprocessor.Use dust particle counting to detect w
The filter aperture of the front filter is 60 or 40. It's too true. there's no need.40 microns and 90 microns have the same effect.The front filter itself is a product for pretreatment of water.It has to ensure that the water flow network can not do too fineA lot of imports are only between 90 and 110 microns. that's why.In China, the accuracy is generally 40-90 microns.However, few of them are made below 40 microns, not practical, with large damping and reduced water flow.At the same time, it is very inconvenient to use it easily.It is made of 10 microns. it is also a product of mixing water with coarse filter water into mixed water.It's only good to stop large impurities.
