1, magnetic column level gauge flange sealing surface is attached with dirt. Solution: Clean the sealing surface.
2. The sealing surface is damaged. Solution: Grind the sealing surface or replace the sealing surface.
Second, the valve stem transfer is not flexible:
1, the valve plug cover angle is too tight or the bearing wear. Solution: Adjust packing tightness or replace bearings.
2. There is debris or dust between the stem or the stem nut, and the stem or stem nut is damaged. Solution: Remove the cleaning stem and replace the stem or stem nut if damaged.
3, the opening and closing device fails. Solution: According to the device manual to check the failure after the maintenance of three, the central magnetic column level gauge flange leakage causes and solutions:
1. The flange bolts are not tightened or loosely tightened. Solution: Loosen the screw and tighten it evenly and symmetrically.
2, gasket damage or failure. Solution: Replace the gasket.
3, there is dirt between the flange sealing surface. Solution: Remove the cleaning flange.
Fourth, the stuffing box leakage:
1, loose packing or packing gland pressure bias. Solution: The packing gland should be pressed evenly.
2, magnetic column level gauge flange packing failure. Solution: Replace with new filler.
