The principle of ultra-clean bench products related to the narrative
The principle of ultra-clean bench products related to the narrativeUltra-clean workbench, also known as a purification workbench, is designed to adapt to the modern industry, photoelectricity industry, biopharmaceuticals scientific research and testing, and other fields of local work area cleanliness needs. The air is sucked into the pre-filter through the fan and then filtered into the high-efficiency filter through the static pressure box, and then the filtered air is sent out in the state of vertical or horizontal airflow so that the operation area reaches the cleanliness of Class 100 to ensure the production of the environmental cleanliness requirements.The ultra-clean bench is a one-way flow of air purification equipment to provide a local dust-free and sterile working environment. It is widely used in scientific research and production departments that need local clean and sterile working environments, such as medicine and health, biopharmaceutical, food, medical science experiments, optics, electronics, sterile laboratory experiments, sterile microbiological tests, orange tissue culture inoculation and so on. It can also be connected to an assembly line with the advantages of low noise and movable. It is a kind of universal air purification equipment that provides a highly clean working environment. Its use to improve process conditions, improve product quality, and increase production has good results. Ultra-clean bench principle is in a specific space, indoor air by the pre-filter primary filtration, by a small centrifugal fan pressed into the static pressure box, and then by the air high-efficiency filter secondary filtration, from the air high-efficiency filter out of the air surface blowing clean airflow with a certain and uniform cross-section of the wind speed, you can exclude the original air of the work area, dust particles, and biological particles away, to form a sterile high-clean working environment. Ultra-clean table power supplies more than three-phase four-wire, one of which is the zero line, connected to the machine shell, which should be firmly connected to the ground, the other three lines are phase lines, with a working voltage of 380 V. The two-wire connection circuit is in a certain order. If the line is connected wrong, the wind will be reversed. At this time the sound is normal or slightly abnormal. No wind in front of the ultra-clean table, you can use the flame of the alcohol lamp to observe the movement, should not try for a long time). You have to cut off the power supply in time and only exchange the position of any two wires before connecting, it can be solved. If only two of the three-phase lines are connected, or one of the three phases has poor contact, indicating that the machine sounds abnormal, you should immediately cut off the power supply, and careful maintenance, otherwise it will burn the motor. This common sense should be explained to the staff at the beginning of the use of ultra-clean tables, exemption should not cause accidents and losses. |
