How to troubleshoot the problem after the installation of liquid tank seal high efficiency filter? This problem is
believed that many customers do not understand, recently a customer in Anhui after the self-installation visit
said: "The air filter purchased before, recently installed after the test found that the cleanliness requirements
are not up to standard, I hope we can help to look at it." After receiving customer information, directly contact
the factory technical clerk to conduct after-sales service, the test process and problem summary by
professionals, and the problem has been solved within 1 day.
CRAC air filter manufacturer 16 years of manufacturing experience only to provide customers with the best
quality service, timely and fast professional has been our service concept, today Xiaorui for you to share the
specific program, do not understand the small partners can be used as a reference:
1. Test process:
1. Install and test three sets in three different rooms;
2, the first installed in the large room, about 8 to 9, installed the filter on the curtain, tested twice, no alarm in
the process, no leakage;
3, the second installation in a small room, a total of 1, installed the filter after direct test, no alarm in the
middle, alarm around; Cloth curtain, still alarm, through the search, found that there is a large gap between
the box and the ceiling, through multiple sealant, until the gap is repaired, the final test without alarm, no
leakage. In the process, it was found that as long as the glue is not in place, there is a little gap, it may alarm;
4, the third installed in a small room, a total of 1, installed on the box first glue seal, and then test, test results:
no alarm in the middle, alarm around; The curtain on the cloth is tested again, the first time there is a point an
alarm, go back to the past and test again, no alarm; After two tests, the results did not appear alarm.
In this process, we also measured the depth of the jelly glue filled by the liquid tank, the jelly glue depth of 17~
18mm, the box knife edge of 15mm, so the jelly glue can completely drown the knife edge of the box, there is
no possibility of jelly glue leakage.
2. Problem summary:
Based on the above, the following conclusions can be made:
1. The box gradually falls during the use of the box, resulting in gaps leading to leaks;
2, measures: this situation needs to glue leakage;
3, there is a lot of dust on the removed filter, in the process of disassembly and handling, the dust on the old
filter pollutes the environment of the clean room; At the same time, if in this process, the air supply pipeline
continues to supply air without the installation of the new filter, the dust in the pipeline will enter the clean
room. The above two situations will lead to a serious decline in the cleanliness of the clean room.
4, measures: First remove all the old filters immediately bagged or packed to reduce secondary pollution; Then
install the new filter, and then ventilation operation, self-cleaning 24 hours later, and then cleanliness test,
basically can avoid the emergence of alarm problems. It should be noted that before installing a new filter,
check the box first to see if there is a gap leak, if there is a gap, be sure to glue the leak.
The final result needs to be ventilated and self-cleaning for 24 hours after all filters are installed and leaks are
repaired, and then judged by the test situation.
