The use and maintenance method of ultra-clean workbench
The use and maintenance method of ultra-clean workbenchThe following is the use and maintenance method of the ultra-clean workbench:Usage method Preparation work: Before use, prepare all the items required for the experiment to avoid pollutants brought into the ultra-clean workbench during the operation. Turn on the equipment: turn on the power, turn on the main switch of the ultra-clean workbench, and then turn on the ultraviolet lamp, and sterilize the working area for at least 30 minutes. After the disinfection is completed, turn off the ultraviolet lamp, turn on the fan and lighting system, and let the fan run for a period to achieve a stable clean state of the working area. Place items: Put the experimental supplies into the ultra-clean workbench, and pay attention to avoid blocking the outlet and return the air outlet when placing, to keep the airflow unblocked. Items should be neatly arranged and easy to handle. Operation: The operator should wear clean work clothes, masks, and gloves, sit or stand in front of the ultra-clean workbench, and extend the arms into the workbench for experimental operation. Try to avoid violent movements during the operation to avoid disturbing the airflow. At the same time, keep the work area clean and avoid leaving debris or pollutants on the work table. End operation: After the end of the experiment, clean up the work area in time, put the waste into the designated trash can, and wipe the workbench with disinfectant. Turn off the fan and lighting system, and cut off the power. Maintenance method Daily maintenance: After each use, wipe the countertop and inner wall with a clean, damp cloth to remove dust and stains. Regularly check the exposure intensity of the ultraviolet lamp, if the ultraviolet lamp is found to be aging or insufficient exposure, it should be replaced in time. Filter maintenance: Regularly check the resistance of the high-efficiency filter, when the resistance reaches a certain degree, the filter should be replaced in time. Under normal circumstances, the replacement cycle of high-efficiency filters is 1-2 years, but the actual replacement time needs to be determined according to the frequency of use working environment, and other factors. When replacing the filter, pay attention to selecting the appropriate model and install it correctly. Fan maintenance: Check the running status of the fan regularly. If the speed of the fan is abnormal or abnormal noise is found, stop the fan for check-in time. Clean the dust in the impeller and volute of the fan to ensure the normal operation of the fan. At the same time, pay attention to the lubrication and maintenance of the fan, and add lubricating oil regularly according to the requirements of the equipment manual. Electrical system maintenance: regularly check the lines and joints of the electrical system to ensure that the connection is firm, with no loosening and leakage phenomenon. If electrical faults are found, the power supply should be cut off in time and repaired by professionals. Regular testing: Regularly test the cleanliness, wind speed, air flow uniformity, and other indicators of the ultra-clean workbench to ensure that its performance meets the requirements. You can use professional testing instruments, such as dust particle counters, anemometers, etc. If you find that the indicators do not meet the requirements, you should find the cause in time and carry out maintenance or adjustment. |
