Mechanical seal cooling water
Thread Content
Dear colleagues in Sichuan, is wastewater treated water or water vaporized from hydrogen production carbonic acid being used as cooling water for pumps? What impact does it have on the mechanical seal after use?
My previous company used this, but the results were not satisfactory. It is best to use clean water sources; after wastewater treatment, there is a risk that crystalline substances of inorganic salts may be present in it. Otherwise, scaling will occur severely near the friction surfaces of the mechanical seal, reducing its service life.
Is the scaling severe? What happens to the acidic aqueous gas after it passes through the dry gas hydrogen production unit?
My cooling system does not use water that has been purified from sewage
Such sealing water must first have the function of preventing the production medium from damaging the sealing material. The water used must be clean, free from corrosion and impurities (as impure liquids can cause wear on the rotor and sealing materials) in order to be used for sealing. For reference.
Generally, this acidic gas water can be reused as spray water at the conversion steam distribution point.
Isn’t this modification intended to save energy and reduce water consumption by the equipment?
The amount of water used for the mechanical seal is not large anyway; it’s not worth the cost of replacing it if it leaks or gets damaged. Using some clean water incurs no significant cost
Acidic water causes severe corrosion; consider carefully
