Stainless steel petrochemical pump considerations

1. As a result of petrochemical pump seal generally applicable in clean, without the suspended particles in the medium of use, therefore, for new installation of the piping system and reservoir filling, should rinse carefully and keep a solid impurities into elevating its mechanical seal face seal failure.

2. In easy to be crystallized media, often should pay attention to the use of mechanical seal flush. After parking before starting again, to wash clean the crystalline on the mechanical seal.

3. Carefully remove the mechanical seal, no hammer, iron and other percussion, lest destroy the dynamic and static ring sealing surface.

4. If there is dirt come down not bottom, should try to remove dirt, after rinse and then to remove, so as not to damage the sealing element.

5. Mechanical seal before installation, should check all packing element for failure or damage, if any should be to repair or replacement.

6. Should strictly check the relative friction ring and static ring sealing surface, do not allow any minor defects such as scratches, bruised. All other components, including pump body, impeller, seal chamber, etc shall be flush thousand net before assembly, especially the dynamic and static ring end face, with a clean, soft cloth or cotton yarn carefully wipe clean, then coated with a layer of clean grease or oil.

7. Pay attention to eliminate the deviation in the assembly, fastening screws, to tighten, prevent deflection, the seal failure.

8. The right to adjust the compression of yellow, after the pump is installed, with lever regulated, should feel seal play yellow has a certain amount of compression, and can fast, flexible rotation not bite tight feeling. If feel too tight or plate, should be the appropriate loose some.

9. For mechanical seal, with external flushing should be opened before starting flushing wave, the sealed cavity filled with seal liquid. When parking, stop the pump first, after closing seal rinses.
