How to maintain the VHP pass box during daily use
How to maintain the VHP pass box during daily useThe daily maintenance of the hydrogen peroxide (VHP) pass box is essential for its normal operation and good performance. The following are specific maintenance methods:Regular cleaning 1. Surface cleaning - Regularly use a clean, soft, and lint-free cloth to wipe the inner and outer surfaces of the pass box, including the door panel, frame, and observation window. For stubborn stains, you can use a mild detergent, but avoid the detergent from entering the inside of the pass box or contacting key components such as the VHP purification module. - The cleaning frequency depends on the use environment. Generally, in an environment with high cleanliness requirements, it is recommended to clean it at least once a day; in an ordinary environment, it is recommended to clean it at least once a week. 2. VHP purification module cleaning - The VHP purification module is one of the core components of the pass box, and its cleaning requires extra care. Use special cleaning tools, such as a soft brush, to gently brush away dust or tiny particles that may accumulate on the surface of the module. - It is strictly forbidden to use water or any corrosive detergent to clean the VHP purification module to avoid damaging the catalyst, sensor, and other precision components in the module. It is generally recommended to perform a simple cleaning of the VHP purification module every 1-2 weeks, and a more in-depth inspection and cleaning can be performed once a quarter (under the guidance of a professional). Regular inspection 1. Component inspection - Regularly check the springs and hinges of the transfer window for signs of looseness, deformation, or wear. Loose springs or hinges may cause the door to not close properly or seal poorly, affecting the performance of the transfer window. If problems are found, the parts should be adjusted or replaced in time. - Check the sealing performance of the door. You can check the sealing performance by observing whether there is a gap between the door and the frame in the closed state, or use a light smoke test (where safe and permitted). If a poor seal is found, it may be that the sealing strip is aging or damaged, and the sealing strip needs to be replaced in time. 2. Glass inspection - Carefully check the glass of the transfer window for cracks, damage, or blurring. Even tiny cracks may expand during pressure changes or use, affecting the structural integrity and visibility of the transfer window. If there is a problem with the glass, it should be replaced in time to ensure safety and normal use. - At the same time, check the sealing of the glass and the frame to prevent air leakage or contamination caused by poor sealing. Maintenance records Establish a complete maintenance record file, and record in detail the time, content, problems found, and solutions taken for each cleaning and inspection. By analyzing the maintenance records, potential problems of the VHP transfer window can be discovered in time, possible failures can be predicted, and maintenance plans can be arranged in advance. It also helps to evaluate the effectiveness of maintenance measures and provides a basis for optimizing the maintenance process. |
