What is the startup sequence for the adsorption fan used to handle exhaust gases when it is started for the first time? How to protect fans?

The initial startup of the adsorption fan for exhaust gas should be carried out in the following order: 1. Open the intake valve to ensure smooth air intake for the fan. 2. Start the motor to enable the fan to rotate properly. 3. Open the exhaust valve of the adsorption tank to allow waste gas to enter it. 4. After confirming that the fan is operating properly, gradually adjust the opening degree of the exhaust valve on the adsorption tank to keep the pressure inside the tank at the set value. During the startup process, the following points should be taken into account to protect the fan: 1. Before starting the fan, check whether electrical components such as the power supply and fuses are functioning properly, as well as whether the oil level is within the required range. 2. The opening degree of the exhaust valve on the adsorption tank needs to be adjusted gradually; either an excessive or insufficient opening can result in excessive load on the fan or unstable pressure, thereby damaging the fan. 3. Regularly clean the adsorption tanks and fans to prevent dust and debris buildup from affecting work efficiency. .
