Attention shall be paid to double and single-sided super clean worktable

Double and single-sided super clean operation platform is widely used in the scientific research and production departments of pharmaceutical and health, biopharmaceutical, food, medical scientific test, optical, electronic, sterile laboratory test, sterile microorganism inspection, plant tissue culture inoculation and other parts of the clean and sterile operation environment It is a one-way flow type air purification equipment that supplies part of the dust-free and sterile working environment It can also be connected into an installation line with the advantages of low noise, mobility, etc It is a kind of air purification equipment which can supply part of high cleanliness working environment with strong universality Its application has a good effect on improving process conditions, improving product quality and increasing yield This paper mainly introduces the key points that should be paid attention to when using the double one side super clean working table The power supply of the super clean platform mostly adopts three-phase four wire, among which there is a zero wire, which connects the machine shell and should be firmly connected to the ground wire The other three wires are all phase wires, and the operating voltage is 380V There is a certain sequence in the three wire access circuit If the wire head is wrongly connected and the wind timing turns, then the sound is normal or slightly abnormal, and there is no wind on the front of the super clean platform (the alcohol lamp flame can be used to investigate the dynamic state, and it is not suitable to test for a long time) The power supply should be cut off in time, and it can be solved only by connecting the wire head of any two phases in the same direction If the three-phase line is only connected to two phases, or one of the three phases is in poor contact, the sound of the machine is very abnormal, and the power supply should be cut off immediately for careful maintenance, otherwise the motor will be burned These knowledge should be explained to the operators at the beginning of using the super clean platform, and the elimination should not cause trouble or loss There is a general foam plastic sheet or non-woven fabric in the metal net cover below the reverse or positive side of the super clean platform inlet It is used to obstruct the large particle dust It should be checked and disassembled frequently In addition to the air inlet, if there is any air leakage hole, it shall be blocked tightly, such as pasting adhesive tape, plugging cotton, pasting glue paper, etc In the metal mesh cover on the front of the work table is the super filter, which can also be replaced If the super filter is used for a long time, the dust particles are blocked, the wind speed is reduced, and the sterile operation cannot be ensured, it can be replaced with a new one The ultraviolet lamp can also be hoisted on the ultra clean operation platform, but it shall be installed outside the lighting shade, and the arrangement of lighting lamps shall be staggered, so as not to hinder the lighting during operation If the ultraviolet lamp is installed in the lighting lampshade (glass plate), it is useless, because the ultraviolet ray cannot penetrate the glass, and its lamp tube is quartz glass, not silicate glass The inoculation room should be concise as much as possible All items that are not directly related to the operation of the room should not be put in, so as to keep sterile The air in the inoculation room should be definitely isolated from the outside air, and the reserved ventilation channel should be as closed as possible The vent passage can be equipped with upper and lower air windows The area of the air windows should be slightly larger, and 4 layers of gauze should be covered for simple dust filtering After a day's work, the windows can be opened for full ventilation, and then sealed All in all, it is clean and sterile, fresh air and suitable for operation The gauze covering the ventilation window should be changed frequently However, the above-mentioned methods are only ideal design schemes, which are not easy to achieve in an all-round way In fact, they are strictly sterile operation procedures In the room with doors and windows open, there is a super clean table maintenance, and the pollution rate of vaccination can still be controlled at a level that can be tolerated in production Double single-sided super clean working table service life and air cleanliness In the temperate zone, the super clean platform can be used in the general laboratory However, in the tropical or subtropical zone, the super clean platform should be used in a better room with double doors, where there is a lot of pollen or dust in the atmosphere Under no circumstances should the air inlet hood of the super clean platform face the open door or window to avoid affecting the service life of the filter Asepsis room should regularly use 70% alcohol or 0.5% phenol spray to dust and disinfect, use 2% new gerune wipe the table and utensils (70% alcohol can also), cooperate with ultraviolet sterilization lamp (each open for 15 minutes or more) and so on disinfection and sterilization means, so that the asepsis room often adhere to the degree of aseptic The incubator should also be equipped with ultraviolet lamp The lamp should be turned on for more than 15 minutes before use to sterilize, but there are still bacteria in the places where the lamp can not shine When the ultraviolet lamp is open for a long time, the oxygen molecules in the air can be activated to form ozone molecules This gas component has a strong bactericidal effect, and can have a bactericidal effect on the corner where the ultraviolet light does not directly shine Because ozone is harmful to health, the ultraviolet lamp should be turned off before entering the operation, and then it can enter within 10 minutes
