Corrosion resistant pump discharge acid hydrochloride WB2 and 169 type mechanical seal when using how to maintain?

anti-corrosive water pump discharge acid hydrochloride WB2 and 169 type mechanical seal when using how to maintain?

pump industry the corrosion of hydrochloric acid pump installation according to the different using conditions and different seal material, our factory discharging hydrochloride acid pump type FSB chemical centrifugal pump normal installation accessory factory sealed as WB2 and type 169, please pay attention to when using the following:

1, general mechanical seal for clean without suspended hard particle medium. If there are particles in order when the contract in advance, please let us know. Series of new pipeline and storage tank, should be carefully rinsed clean, keep a solid particles into the seal face, make the seal failure.

2, in the crystallization medium, the use of mechanical seal, attention should be paid to often wash, before restarting after parking, make the crystallization of the seals is rinsed clean.

3, carefully remove the mechanical seal, no hammer, the content such as iron forced percussion, lest destroy dynamic and static sealing surface.

4, if the mechanical seal dirt after long-term use of strong come down not bottom, not to knock. Should try to remove dirt, rinse, then remove and the guarantee element is in good condition.

5, mechanical seal before installation, should check whether the machine sealing element is first failure and damage, if any, should be to replace or repair, strict inspection of dynamic and static sealing surface damage, do not have any minor scratches, broken edge and defect, all the parts ( Including water pump body, impeller, back cover, seal chamber before the machine is rinsed clean, then coated with a layer of clean grease or oil.

6, assembly, pay attention to the parallel degree of static ring and the back cover, to prevent affect the sealing effect.

7, properly adjust the spring compression force, make it not too tight is too loose, installing a pump to rotate with the hand, should feel seal has certain compression force, and can fast and flexible rotation, such as not feeling adjusting spring compression force, to ensure the sealing effect.
