  • How to measure the air volume of high-efficiency air box

    How to measure the air volume of high-efficiency air box
    High-efficiency air box are ideal terminal filtration devices, widely used in medicine, health, electronics, chemicals and other industries. In order to verify whether the clean room can meet the cleanliness requirements, it is necessary to test the clean room and high-efficiency air box, so its detection is very important.    How to measure the air volume of high-efficiency air box:  1. You can use the air volume hood to directly aim at the nozzle for one-time measurement, direct measurement. Since your nozzle has many small holes (to make the air volume uniform) and there is a grille, then your anemometer can be kept 3-5 cm away from the nozzle. If you have a thermal anemometer, try to face the gap instead of the grille, and measure the average value by the grid method. The same cross-section can be measured. 2. You can measure at multiple points at a distance of 2 times the width of the diffuser from the air outlet. The measuring points should be like a grid and then the wind speed is averaged. The sizes of these vents are similar. Use tinplate or even plastic board to make a barrel that is slightly larger than the cross-section of the air box. When measuring, cover the barrel on the air box and use the anemometer to measure the nozzle of the barrel at multiple points and then calculate the average value. 3. Through the clean air conditioning circulation fan, through the high-efficiency air filter, medium-efficiency filter, and primary air filter, clean air can be obtained. The cleanliness is different and the wind flow direction is different. Of course, it is also necessary to supplement some fresh air through the fresh air box, otherwise people will feel stuffy inside.      Air volume measurement of high-efficiency air box:  1. The detection method of high-efficiency air outlet uses active sampling and passive sampling. Active sampling uses filtering method and impact method. Filtration method allows a certain amount of air to pass through an analytical filter. 2. The impact method can use Anderson sampler, Lute centrifugal sampler, and slit sampler. Passive sampling uses the landing method. Use the principle of diffusion of the open agar plate of suspended particles. 3. Of course, with the development of science and technology today, some more sophisticated detection instruments can also be used to quickly detect it.

  • What purification equipment needs to be installed in the clean room

    What purification equipment needs to be installed in the clean room
    Nowadays, many companies need to produce products in a clean room, such as large food production and processing and electronics production factory. Therefore, many companies are using clean room. The reason why clean room can be dust-free is mainly because a lot of high-tech purification equipment was installed in the clean room during decoration.     1. The air inlet system of clean room must be installed filter box, and a central purification air conditioner (the central purification air conditioner must be divided into three filter sections: primary efficiency /medium efficiency/high efficiency) with a high-efficiency air supply port at the end. It's necessary to install a purification booster box if need. 2. the return air system of clean room must be installed, including a return air outlet, a pre filter, and a middle filter return air box. 3. Enter the buffer zone before entering cleanr room. Electronic interlocks are installed on the buffer zone door, and clean storage cabinets and air fresheners are placed in the changing area. People and goods entering the clean room, must pass through the air shower, cargo shower room, and use pass box to mainly transfer small items. 4. In the clean room, vertical clean bench, laminar flow hood (FFU), clean booth (removable clean booth) and self-purifier should be installed in some places that need to reach level 10-1000. Laser dust particle counter for measuring the cleanliness of clean rooms. 5. The clean room build should be designed with observation windows to facilitate visits.    Clean room equipment:  1、Air shower, changing room and clean room are the three basic components of the workshop purification system. The air shower is a passage in and out of the clean area. The high-speed clean air jetted out can effectively and quickly remove dust and bacteria carried by the human body. The clean room uses interlayer color steel plates to isolate the space and walls, the upper color steel ceiling is suspended, and the floor is paved with epoxy resin. 2、The most important role of air purification equipment in a clean room is to control the cleanliness, temperature and humidity of the atmosphere that products are exposed, so that products can be produced and manufactured in a good environmental space. This space is called a clean room. 3. According to the clean room management regulations, the dust-free purification level is mainly determined based on the number of particles per cubic meter of air that are greater than the classification standard. But for optical structures, a small dose may produce a very large amount, so air purification equipment is needed to build in clean room.     The above content is the purification equipment that needs to be used in the clean room. Different purification levels have different requirements for purification equipment. This mainly depends on the production needs of each enterprise.
