Maintenance of high-efficiency filters
Maintenance of high-efficiency filtersHigh-efficiency filter manufacturers recommend that the interior of the high-efficiency filter system should be cleaned once every half a month, and regular maintenance can effectively extend the service life of the instrument.The high-efficiency filter should be unboxed at the site, and when replacing the high-efficiency filter, firstly, wipe the inside of the high-efficiency filter, the four frames, and the periphery with a wet rag and repeat it three times, and then wipe it comprehensively with a dry rag; and the high-efficiency filter should be installed immediately after the inspection is qualified, to prevent the dust from falling into the high-efficiency filter. While scanning and inspecting, tighten the bolts or plug the leakage with epoxy resin silica gel; the number of suspended particles in the clean room is detected to be exceeding the standard, and the final air volume of the high-efficiency filter is reduced to less than 70% of the initial air volume; When the surface of the high-efficiency filter is not very dirty, the high-efficiency filter will be taken outdoors to be blown clean with clean compressed air on both sides, and the dust particles will not be seen under the light with the eyes; when the surface of the filter is very dirty, it is necessary to carry out water washing. In the general area of the water room (air-conditioning room) with a slot into about 100 pounds of cited water, 1 kg bottle of detergent diluted, the filter into the slot to be fully submerged in water. Rinse several times, to no dirt, and then rinse with water until the water is clear, take out on the stainless steel grille floor mopping dry water, and then flat on the shelf drying, cool to both sides of the hard flip to speed up the drying rate. After the replacement of the high-efficiency filter, a leakage test should be carried out and verified; high-efficiency filter testing, replacement should be recorded promptly; after the replacement of the high-efficiency filter, dust particle counter leakage test on the high-efficiency filter installation connection. |
