Sulfuric acid pumps often malfunction
Thread Content
The temperature has not been very low recently, and the waste sulfuric acid pumps used in our factory often fail to function properly. The waste sulfuric acid we use is 80% concentration.
Reply: The waste sulfuric acid pumps used in our factory often fail to measure the volume. The waste sulfuric acid we use is 80% concentration. The possible reasons for the sulfuric acid pump not being able to lift fluid include: 1. Corrosion and detachment of the impeller ； 2. The impeller is clogged ； 3. Does the motor reverse direction? ； 4. If it is a horizontal pump, air leakage at the pump inlet can also cause the pump to fail to deliver fluid; please check each possibility one by one ；
Damage to the impeller key can also cause the pump to fail to deliver flow
I agree with what was said on the 2nd floor; I have been involved in the repeated repairs of sulfuric acid pumps.
80% concentrated sulfuric acid is highly corrosive; it is recommended to use Hastelloy or non-metallic pumps (such as fluoroplastic centrifugal pumps).
