Correctly Open The Filtered Bag Filter Upper Cover

Warning: Do not open the cover when there is pressure in the bag filter, otherwise the remaining liquid may spray out, causing liquid loss and personal injury.
Therefore, please strictly follow the following order:
1) Close the input valve; when there is pressure at the outlet, close the output valve.
2) After confirming that the pipe connected to the exhaust valve has been connected to a safe place or suction port (especially when filtering toxic and corrosive liquids), open the exhaust valve to prevent the liquid from causing harm to the staff and the surrounding environment. pollute.
3) Check the pressure gauge to make sure the internal pressure is 0. At this time, the bag filter should be separated from the piping system.
4) If there is a drain valve, confirm that the drain liquid is received at the recovery point, open the drain valve; wait until the remaining liquid in the bag filter has drained out through the drain valve, then close the drain valve. This discharge work can be completed with pressurization (please refer to the pressurized discharge process).
5) Unscrew the hanging cap of the upper cover, lift the upper cover, and the multi-bag filter needs to rotate at a certain angle.
