【正文】 uid type ( or ) filters and collects the pellet with the millipore filter, then examined under the microscope. If discovers the biggest pellet for 20μm, then filter fineness for 20μm. ③ The air cleaner, the purification environment use the filter, usually by weight filter efficiency nominal filtration characteristic. The custom said that several “9” the field test powder is ACFTD. Although above 3 kind of filter39。s filter fineness defines differently, but based on one test method, namely pellet transmission law, Therefore the modern filtration counting abolished the former aperture measuring method to the filter characteristic evaluation and filters the material item of number law, but still continues to use in coal profession many enterprises and the user filters the material number law. This causes in the market the same 25μm filter operational accuracy difference to be very big. On the other hand, regarding the high accuracy filter (25μm), filters the material the choice and the processing is very strict, some enterprises cheat on labor and materials the choice to filter the material or the processing craft inferior do not go through a strategic pass, create the filter element processing flaw. Although filters the material choice to be appropriate because, but the processing craft is unqualified causes the filter end product precision to reduce obviously, cannot satisfy the system request. Therefore should formulate the battery solution control system to produce, the processing and examination profession standard especially important as soon as possible with the filter. ④ Entire filtration system not perfect or inadequate system, creates the system existence crack or the system function cannot display fully, serious influence battery solution control system performance display. Because does not have the filtration or the filter position is inappropriate, creates key protects the part not to obtain the protection, even if on the other hand had the filtration system, must plete the prevention, avoids the pollutant entering the system as far as possible, achieves cleanliness guarantee system which the driving prevention and the passive filtration protection unify, only then can guarantee the entire battery solution control system39。s reliable steady operation like this conclusion The hydraulic support battery solution control system realizes the coal mine safety highly effective mining key technologies, realizes the high production highly effective working surface essential condition. But must use the good battery solution control system, the display battery solution control system39。s superiority truly, only through improves the battery solution control system itself quality to be not enough. Must from the support and the hydraulic services production, the medium cleanliness control and onsite maintenance and so on several aspects begins together, can demonstrate the battery solution control system39。s superiority fully.
