There is no pressure at the outlet of the sulfuric acid circulation pump
Thread Content
The hydrogen chloride obtained after drying is used with concentrated sulfuric acid; the pump used for circulating this concentrated sulfuric acid often fails to operate properly. The specific fault symptom is a lack of pressure at the pump outlet. The pump in question is an anti-corrosion magnetic pump with a flow rate of 12.5 cubic meters per hour and a head of 20 meters. It operates at room temperature, with the sulfuric acid concentration being at least 85%. The drying tower is made of steel lined with PE, and the packing inside it is arranged in a disordered manner; there is also a dedicated circulation tank for the sulfuric acid. Please, experts, help me make a judgment. Thank you
Maybe the magnetic coupling is broken?
The broken magnetic coupling was easily fixed
