Related descriptions about the product principles of ultra-clean workbenchA clean bench, also known as a purification workbench, is designed to meet the demand for the cleanliness of local work areas in modern industry, optoelectronics industry, biopharmaceuticals, scientific research and experiments, and other fields. It sucks the air into the pre-filter through the fan, enters the high-efficiency filter through the static pressure box, and sends the filtered air out in a vertical or horizontal airflow state, so that the working area reaches 100-level cleanliness, ensuring that the production environment is clean. Require.The ultra-clean workbench is a one-way flow air purification equipment that provides a local dust-free and sterile working environment. It is widely used in scientific research and production departments that require a local clean and sterile working environment, such as medicine and health, biopharmaceuticals, food, and medical science. Experiments, optics, electronics, sterile laboratory experiments, sterile microbial testing, plant tissue culture inoculation, etc. It can also be connected to an assembly line, which has the advantages of low noise and mobility. It is a general air purification equipment that provides a local high-cleanliness working environment. Its use has a good effect on improving process conditions, improving product quality, and increasing output. The principle of an ultra-clean workbench is that in a specific space, the indoor air is initially filtered by the pre-filter, pressed into the static pressure box by a small centrifugal fan, and then filtered through the secondary filter of the high-efficiency air filter. The blown clean airflow has a certain and uniform cross-sectional wind speed, which can eliminate the original air in the work area and take away dust particles and biological particles to form a sterile and highly clean working environment. Most clean bench power supplies use three-phase four-wires, one of which is the neutral wire, which is connected to the machine shell and should be firmly connected to the ground wire. The other three lines are all phase lines, and the working voltage is 380V. There is a certain order for three-wire connection circuits. If the wires are connected wrongly, the wind will be reversed. The sound is normal or slightly abnormal at this time. There is no wind in front of the clean bench (you can use the flame of an alcohol lamp to observe the movement, but it is not advisable to try for a long time). You need to cut off the power in time and just exchange the positions of any two wires before connecting, and the problem will be solved. If only two phases are connected to the three-phase wire or one of the three phases is poorly connected, it means that the machine sounds abnormally and should be Cut off the power supply immediately and maintained carefully, otherwise, the motor will be damaged. This common sense should be explained clearly to the staff at the beginning of using the clean bench. Disclaimer should not cause accidents and losses. |
