Fluoroplastics alloy centrifugal pump in use, inevitable failure. These failures may have a greater impact on the use of Fluoroplastics alloy centrifugal pumps, which may not only delay the production but also affect the service life of Fluoroplastic alloy centrifugal pumps. Next, we will bring fluorine plastic alloy centrifugal pump failure analysis and solution introduction. Fluorine plastic alloy centrifugal pump failure analysis and solutions 1, can not hit the liquid Fault analysis: the suction pipe air, the entrance obstruction; suction on the height is too high; requires lift greater than the pump head; solution: clean up the pipeline, ; Reduce the pump installation height; more head large pump; 2, insufficient flow Failure Analysis: impeller damage; seal damage; insufficient number; solution: update impeller; seal; increase the number of revolutions; Medium containing gas or medium viscosity is too large; impeller and blade damage; insufficient number of revolutions; solution: to reduce the viscosity of the medium or increase filling pressure; change impeller; increase the number of revolutions; 4, shaft end leakage Failure Analysis: Mechanical Seal Card The ring is too loose; the shaft end snap ring transitional size gap is too large; solution: tighten the card bad two hexagonal screw ruthenium; the pump disassembly, the shaft, the card stuck around the F4 raw material film with a few laps; tight fit. Tight; 5, seal leak serious Failure Analysis: improper selection of sealing element material; grinding 瘵 pay serious wear; moving ring kiss is not the solution: Suitable ring; more other wear member, and adjusts the spring pressure, reducing wear; Songka seal ring assembly screws align the position of the pin again. Fluoroplastic alloy centrifugal pumps are mainly used in China's chemical, petroleum, pharmaceutical, printing and dyeing, papermaking, smelting, food and other industries, its use to help these industries have made great strides. Although the fluorine plastic alloy centrifugal pump there are many inherent deficiencies, but I believe in the market demand and help from all walks of life, these difficulties will be solved very well.
