Eight maintenance points of sampling car

1 According to the cleanliness of the environmental workshop, remove and clean the primary filter and intermediate filter regularly; the cleaning time is generally once every 2-3 months; the simple and direct method is visual inspection; whether there are many dust particles on the non-woven filter material; whether there is blackening on the surface If it can be removed, washed or replaced for sterilization, the surface of the UV sterilization lamp shall be wiped clean with gauze and alcohol after frequent use, so as to keep the surface clean, otherwise the sterilization ability of the sampling vehicle will be affected 2 After the sampling of the sampling car, first brush away the sundries and floating dust in the clean work area with a brush in the same way as above, wipe the surface stains in the work area with a fine soft cloth, and there is no detergent residue through visual inspection, dry with a clean cloth, so as to make the internal and external surfaces bright and clean without stains 3 Clean the instrument immediately after each use, hang corresponding marks, and fill in the instrument use record in time 4 Regularly measure the cleanliness of the working area with the dust particle counter every three months as the cycle, and measure the average colony number of the clean sampling vehicle with the plate method When the technical parameters are not met, find out the reason and repair in time 5 If the input voltage of the sampling vehicle and the blower can't make the average wind speed of the purification work area reach 0.32m/s-0.48m/s, it means that the dust capacity of the air filter tends to be saturated and has failed, so it must be replaced 6 If the filter must be placed after the top cover plate of the clean sampling vehicle is opened, remember that when installing the air filter, the arrow mark should point to the air flow direction (i.e downward) 7 After replacing the filter, it is necessary to check whether the surrounding frame is well sealed with dust particle counter again If necessary, silica gel can be used for plugging Then the input voltage of the fan is adjusted to keep the average wind speed in the purification area within the range of 0.32m/s to 0.48m/s 8 Carry out maintenance and inspection once a month, and fill in instrument maintenance records for storage Shanghai Sujing Industry Co., Ltd if you have any need, you can pass with us at any time Thank you very much for your support and look forward to cooperating with you Thank you & bestragard!
