Mastering these points will help extend the life of the double clean bench

The double super clean bench is mainly provided by the air supply filter plate The clean air drops through the operation area at a specific speed It is separated in the middle of the operation area It is sucked away by the front air suction hole and the rear suction window The air sucked in the front and rear parts of the lower part of the operation area is mixed together and pumped into the rear positive pressure area by the blower, which is on the upper part of the machine 30% of the gas is discharged from the top through the exhaust filter plate, and about 70% of the gas re enters the operation area through the oxygen supply filter plate In order to supplement the air discharged from the exhaust port, the same volume of air is supplemented from the room air through the operation port These air will not enter the operation area, but form an air barrier The double super clean working table is formed by the flow of clean air (intake air) in a specific space according to the set direction According to the air flow direction, the existing super clean bench can be divided into vertical type, inward outward type and lateral type Considering the operation quality and the impact on the environment, the vertical type is superior In the later period of use, we always hope that the service life of the equipment can be longer, especially for some large-scale equipment Then, how can we make the service life of the equipment longer? Relevant technical personnel of Shanghai Sujing industry said that mastering these points would help to extend the service life of the double super clean workbench: 1 When using the ultra clean worktable, many problems need to be noticed The ultra clean worktable must be used in the purification room, otherwise it cannot meet the purification requirements If there is no condition, it must also be used in the room with clean environment Secondly, before using the ultra clean worktable, it is necessary to clean the worktable with alcohol, and then turn on the ultra clean working fan and ultraviolet lamp Minutes later 2 Many people think that there will be no problem without cleaning the table before each use, but in fact, this view is wrong Experts suggest: "everything should be done according to Zui's strict requirements, and we should adhere to it." In addition, every time the operator uses the super clean table, as long as the necessary items are kept, the redundant items will affect the effect of air purification flow 3 After replacing the filter, use the dust detector to check whether the four surrounding areas are sealed well, adjust the voltage of the fan unit to keep the average wind speed in the working area within 0.4m/s ± 20%, and use the dust detector to check the purification efficiency Fifth, the electrical parts are installed on the right side of the box If there is any electrical fault, please refer to the electrical schematic diagram and electrical wiring diagram for repair 4 Ultra clean worktable is designed to meet the needs of modern industry, photoelectric industry, biopharmaceutical industry, scientific research and experiment and other fields for the cleanliness of local working areas If we do not pay attention to the operation specifications and regular maintenance, not only the service life of ultra clean worktable will be greatly shortened, but also the relevant experiments and production will be affected Therefore, the operator needs to be clear about the relevant precautions and put them into practice 5 The filter material in the coarse filter shall be removed and cleaned regularly according to the cleanliness of the environment, and the time interval is generally 3-6 months If the filter fails to meet the specified requirements, the alarm will beep and prompt the user to replace the filter immediately to protect the user's safety 6 When the fan unit voltage is adjusted to Zui, and the average wind speed in the working area still fails to meet the technical parameters, the air filter shall be replaced 7 When changing the filter, first open the prefilter at the top of the air supply body, and then remove the fan plate Pay attention to the arrow mark of the filter when changing The arrow point is the laminar flow direction 8 Of course, the operator should also check the air speed of the air outlet regularly If the air speed is lower than the factory specified value, the filter needs to be replaced After the filter is replaced, it can be used only after passing the test with the dust particle counter In addition, clean the ultra clean worktable thoroughly at least once a week.
