AI Technical Summary
Centrifugal pumps in phosphate systems are prone to malfunctions during startup due to viscous materials, particulate matter, or crystal deposits, especially after the pump stops, which can lead to blockages in the inlet and outlet pipes or impeller jamming.
A fault-prevention device including a cleaning fluid pipe, valves, and a cleaning fluid pump was designed. By cleaning the centrifugal pump with high-pressure cleaning fluid or clarifying fluid during online cleaning and pre-shutdown cleaning, material sedimentation and crystallization are prevented, thus avoiding malfunctions.
It effectively prevents centrifugal pump failure, extends the effective working time of the equipment, improves production efficiency, and is flexible in operation, allowing cleaning to be carried out without stopping the pump.
