How to adjust the airflow speed of the vertical flow table?
How to adjust the airflow speed of the vertical flow table?The adjustment method of the airflow speed of the vertical flow table is as follows:Voltage regulation via fan: Many vertical flow tables are equipped with fan systems with adjustable voltage. For example, some worktables change the fan speed by rotating the knob that controls the fan voltage and then adjust the airflow speed. Usually, the new workbench begins to use or normal exchange, cleaning the initial effect of the air filter, if the ideal cross-section wind speed can not be achieved, it can be solved by adjusting the working voltage of the fan, generally adjusting the working voltage of the fan to 80V~90V to achieve the ideal uniform wind speed. Use the air volume adjustment switch: some vertical flow table is equipped with a light touch air volume adjustment switch, press the switch to achieve two-speed adjustment or step-less adjustment of voltage within a certain range, in order to control the fan speed, so that the wind speed in the working area is in an ideal state. Adjusting the area of the air outlet or return air outlet: Changing the opening size of the air outlet or return air outlet can adjust the flow rate and speed of the air. For example, if the outlet area is properly increased, the airflow speed will be reduced when the fan power is unchanged; If the outlet area is reduced, the airflow speed will be increased. However, caution should be exercised during operation to avoid affecting the uniformity of airflow and the pressure balance in the workbench. For example, the outlet area can be changed by fine-tuning the shutter Angle of the outlet. 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 that matches the workbench should be selected to ensure that the airflow speed meets the working requirements, and to ensure the normal operation and safety of the workbench. For example, the power of the original fan is small, and it can be replaced with a slightly larger fan of the same type to improve the airflow speed. Calibration and monitoring: Use special calibration equipment (such as an anemometer) to check the wind speed regularly to ensure that it meets the specified standards of the equipment and experimental and production requirements. According to the test results, the fan speed and airflow rate are adjusted accordingly. |
