OneIntroduction
As the core component of the vacuum system, the stable operation of the Shimadzu molecular pump controller is essential to ensure the vacuum level. However, in the actual use process, Shimadzu molecular pump controller may have water ingress failure due to various reasons. This article will analyze in detail the causes of water ingress into Shimadzu's molecular pump controller, and propose corresponding maintenance methods, in order to provide reference for relevant maintenance personnel.
Shimadzu molecular pump controller, as a high-performance precision instrument, has a wide range of applications in scientific research and industry. However, we recently received a repair case about water ingress into the controller, and the following is a detailed analysis of the repair process and the reasons behind it.
IIShimadzu molecular pump controllerAnalysis of the causes of water ingress
1.Poor sealing performance: The sealing performance of Shimadzu's molecular pump controller is a key factor in preventing water ingress. If seals are aged, damaged, or improperly installed, water molecules can seep into the controller and cause failure.
2.Environmental factors: High humidity in the use environment or the presence of water sources around the equipment, such as leaks in cooling water pipes, may also cause water ingress into Shimadzu's molecular pump controller.
3.Improper maintenance: Failure to clean up condensate in a timely manner or to regularly check the sealing performance during equipment operation can lead to water molecules gradually seeping into the controller.

1.Disassembly inspection: First of all, the Shimadzu molecular pump controller needs to be disassembled to check whether there are obvious water traces or corrosion phenomena inside. At the same time, the seals should be carefully inspected, and replaced in time if there is aging, damage and other phenomena.
2.Drying treatment: For Shimadzu molecular pump controllers that have already been flooded, drying treatment is required. Hot air drying, vacuum drying and other methods can be used to ensure that the water inside the controller is completely evaporated.
3.Repair or replacement of parts: Based on the results of the inspection, the damaged parts are repaired or replaced. If the seal is aged or damaged, it should be replaced in time; If the circuit board is damp or corroded, it can be cleaned, dried and repaired.
4.Reassembly & Testing: After the repair is completed, the Shimadzu molecular pump controller is reassembled and functionally tested. Ensure that the functions of the controller are normal and there is no water leakage.
4. Preventive measures
1.Improve sealing performance: regularly check the status of the seal, if there is aging, damage and other phenomena should be replaced in time. At the same time, make sure that the seals are installed correctly to improve the sealing performance of the controller.
2.Improve the use environment: Reduce the humidity of the use environment as much as possible and keep the surrounding area of the device dry. For equipment with water sources, it is necessary to regularly check whether there is any leakage in the cooling water pipes, etc., and find and deal with them in time.
3.Strengthen maintenance: Regularly maintain Shimadzu's molecular pump controllers, clean up condensate, check sealing performance, etc. At the same time, make a record of equipment use, find and deal with problems in time.
