How to adjust the airflow speed of the vertical flow table?
How to adjust the airflow speed of the vertical flow table?There are several methods for adjusting the airflow speed of the vertical flow table:Voltage regulation via fan: Some vertical flow tables are equipped with a fan system with adjustable voltage. By turning the knob that controls the voltage of the fan, the speed of the fan can be changed to adjust the airflow speed. For example, when the new workbench is used, the working voltage of the fan can be adjusted to 80V~90V to achieve the ideal uniform wind speed. If the normal replacement or cleaning of the initial effect air filter, still can not achieve the ideal cross-section wind speed, can also be solved by adjusting the working voltage of the fan. Use the air volume adjustment switch: some vertical flow table is equipped with a light touch air volume adjustment switch, by pressing the switch can achieve two-speed adjustment or step-less adjustment of the voltage within a certain range, and then control the fan speed, so that the wind speed in the working area is always in an ideal state. Replace fans of different specifications: If the fans of the workbench are damaged or their performance does not meet requirements, replace them with fans of different power or speed. However, when replacing the fan, it is necessary to select the fan that matches the workbench to ensure that the airflow speed meets the working requirements and ensures the normal operation and safety of the workbench. Adjust the air outlet or return air outlet area: By changing the opening size of the air outlet or return air outlet, you can adjust the flow rate and speed of the air. For example, if the air outlet area is properly increased, the airflow speed will be reduced when the fan power is unchanged; On the contrary, if the outlet area is reduced, the airflow speed will increase. However, this method requires careful operation so as not to affect the uniformity of the airflow and the pressure balance within the table. When adjusting the airflow speed of the vertical flow table, it is necessary to use professional tools such as anemometers to regularly check the wind speed to ensure that it meets the specified standards of the equipment and the requirements of experiments and production. At the same time, you should also refer to the operating instructions and relevant technical specifications of the workbench to correctly adjust the operation, and do a good job of maintenance to ensure the stable performance of the workbench. |
