The clean transfer window is the supporting equipment of the clean workshop. It is installed between different cleanliness levels to transfer items. Even if the items are self-cleaning, they can also act as an airlock to prevent air convection between the clean rooms.
Mechanical interlocking device: the internal use of mechanical form to achieve interlocking, when one door is opened, the other door cannot be opened, and the other door must be closed before the other door can be opened.
Electronic interlocking device: the internal use of integrated circuits, electromagnetic locks, control panels, indicator lights, etc. to achieve interlocking, when one door is opened, the door opening indicator of the other door does not light up, indicating that the door cannot be opened, and the electromagnetic lock Actions are interlocked. When the door is closed, the electromagnetic lock of the other door starts to work, and the indicator light will light up, indicating that the other door can be opened.
The transfer window is the auxiliary equipment of the clean room, which is mainly used for the transfer of small items between the clean area and the clean area, and between the clean area and the non-clean area, so as to reduce the number of door openings in the clean room and reduce the pollution to the clean room. reduced to a low level. However, if the existing clean transfer window is not installed properly, it is easy to cause pollution. At the same time, if the cleanliness is not enough, it will cause pollution to the clean area
What problems are prone to occur in the clean transfer window:
1. Interlocking failure: There are generally two reasons why the mechanical interlocking transfer window cannot be interlocked: the interlocking hook cannot hook the transfer window door properly. There is also a failure of the interlocking mechanical system. Generally, there are problems with the two internal hook springs, such as breakage, aging, etc. The solution is to replace the springs.
2. The handle is broken: it can be replaced after disassembly.
3. The UV lamp does not light up: Use a multimeter to check whether the UV lamp is in normal contact, or if it has been used for a long time, it has aged and burned.
4. No shower: Check whether the power indicator light is on, if it is on, then check whether the fan is burnt out, if not, then check whether there is a problem with the electronic device.
5. Reduced wind speed: replace the filter in the window.
When deploying the clean transfer window, once the problem of failure occurs, it should be dealt with and solved in time, and then the cause should be investigated to understand the problem of the deviation and the result of the solution, and require immediate treatment of the deviation. Analyze the reasons for these items, and then make corrections.
In the process of installing and operating the clean transfer window, many problems are prone to occur. As long as the problems and deviations occur, they can be used normally as long as they are solved in time. Therefore, these problems can be dealt with, and they can be used after confirmation. Maintenance and upkeep can also reduce the occurrence of problems.
