How do troubleshoot problems after installation of a liquid tank seal high-efficiency filter?
How do troubleshoot problems after installation of a liquid tank seal high-efficiency filter?Liquid tank-sealed high-efficiency filters are commonly used in industries with high cleanliness requirements. Because the sealing performance of this filter is favored by customers, it is widely used. However, after many customers purchase it and install it themselves, they will find that there are leaks in the clean room. The cleanliness is not up to standard. How should we solve this problem? Specific Changrui air filter manufacturers will explain to you one by one:1. Testing process: 1. A total of three units were installed and tested, respectively in three different rooms; 2. The first installation was in a large room, with about 8 to 9 units. After installing the filter, a curtain was put up and tested twice. There was no alarm or leakage during the process; 3. The second one is installed in a small room. There is a total of 1 unit. After installing the filter, it is tested directly. The alarm does not alarm in the middle but alarms all around. After putting up the curtain, the alarm still occurs. After searching, it was found that there was a large gap between the box and the ceiling. For the gap, apply sealant several times until the gap is repaired. In the final test, there was no alarm or leakage. During the process, we discovered that as long as the glue is not applied properly and there is a slight gap, the alarm may be triggered; 4. The third unit is installed in a small room, a total of 1 unit. After installation, seal the box with glue and then test. The test results no alarm in the middle, but alarms on all sides; put the curtain on and test again. The first time there is an alarm. Click the alarm once, go back and test again, no alarm occurs; then test it twice, and the result is no alarm again. During this process, we also measured the depth of the jelly glue filled in the liquid tank. The jelly glue depth is 17~18mm and the knife edge of the box is 15mm. Therefore, the jelly glue can completely submerge the knife edge of the box and there is no jelly glue leakage. possibility. 2. Problem summary: To sum up the above situation, the following preliminary inferences are made: 1. The box gradually falls during use, causing gaps to cause leakage; 2. Measures: In this case, glue is required to fix the leak; 3. There is a lot of dust on the removed filter. During the disassembly and transportation process, the dust on the old filter polluted the clean room environment; at the same time, if the new filter is not installed during this process If the air supply duct continues to supply air, the dust in the duct will enter the clean room. Both of the above situations will lead to a serious decline in the cleanliness of the clean room. 4. Measures: First remove all old filters and then bag or pack them immediately to reduce secondary pollution; then install new filters, then ventilate and run them. After self-cleaning for 24 hours, perform cleanliness tests. Testing can avoid alarm problems. One thing to note is: that before installing a new filter, check the box first to see if any gaps are leaking. If there are gaps, be sure to apply glue to fix the leaks. The final result needs to be determined by ventilating and self-cleaning for 24 hours after all filters are installed and leak repairs are completed, and then based on the test results. |
