The most important feature of corrosion-resistant centrifugal pumps is their long-term transport of corrosive media such as strong acids and alkalines. Its characteristics are mainly due to its material composition and design process. However, corrosion-resistant centrifugal pump after a long period of work, also exposed is not a problem, these failures have brought a lot of work affecting production. Next, we will bring corrosion-resistant centrifugal pump failure analysis and solutions. Corrosion-resistant centrifugal pump failure analysis and solutions 1, the pump shaft swing amplitude is too large Failure Analysis: Bearing wear and tear caused by excessive clearance between the two. Solution: replace or repair bearings, adjust the gap. 2, hydraulic imbalance Failure Analysis: Corrosion-resistant centrifugal pump impeller imbalance, centrifugal pump tank blocked or damaged. Solution: re-school impeller static balance and dynamic balance, eliminate clogging, repair or replacement of the impeller. 3, corrosion-resistant centrifugal pump based on the vibration Fault analysis: loose ground screw or foundation stiffness is relatively poor. Solution: Tighten the screw feet, reinforcement corrosion-resistant centrifugal pump bottom of the foundation. 4, manual crank difficult Fault analysis: Bearing wear, pump shaft bending, the unit is not the heart. Solution: Repair or replacement of bearings, pump shaft correction, re-school unit concentricity. 5, centrifugal pump unit efficiency dropped sharply with cavitation noise Solution: change the corrosion-resistant centrifugal pump speed, to avoid the resonance area, check the cause of cavitation occurs, take appropriate measures to eliminate cavitation. In recent years, China's chemical industry continues to improve, many industries in its promotion, has also made great progress, in particular, corrosion-resistant centrifugal pumps, from its birth to the present widely used in various jobs, its performance has been Many users of the affirmation and appreciation. Believe that in such an optimistic and positive market demand, the future of corrosion-resistant centrifugal pumps will be more worth the wait.
