Analysis of Self - priming Centrifugal Pump Faults and Solutions

Self-priming centrifugal pump has the advantages of strong sewage discharge capacity, high efficiency and energy saving, good self-priming performance, etc. These types of products are suitable for urban environmental protection, construction, fire fighting, chemical, pharmaceutical, dye printing and dyeing, brewing, electric power, electroplating, Paper, oil, mining, equipment cooling, unloading oil tanker and other fields, but as its use continues to increase, self-priming centrifugal pump exposure problems and the use of fault is gradually revealed. So self-priming centrifugal pump failure what? What are the corresponding solutions? Self-priming centrifugal pump failure analysis and solutions 1, Self-priming centrifugal pump body heat failure Analysis: lack of oil, or oil circulation is poor; poor quality lubricants, impurities rust bearings, wear and rotation is not flexible; solution Methods: replacement of qualified lubricants and clean up bearing impurities, adjust the bearing clearance; 2, self-priming centrifugal pump is not on the amount of Failure Analysis: inadequate irrigation pump; pump steering is wrong; pump speed is too low; , The bottom valve is not working Solution: re-irrigation pump; check the direction of rotation; check speed, increase speed; check the motor and power supply; check the filter to eliminate debris; 3, the pump can not start or start the load Large Fault Analysis: Power is not normal; pump stuck; packing pressed too tight; outlet valve is not closed; balance pipe is not smooth; solution: check the power and prime mover situation; hand disk coupling inspection, disintegration inspection, Partial failure; close the discharge valve, restart; everything can not be perfect, their existence more or less have some defects or deficiencies. This is not God's mischief. These inadequacies give us room for growth and progress so that we can continuously improve and progress with the needs of society and the market. Like the self-priming centrifugal pumps, the faults that may occur at work include: A lot, but as long as we find a suitable solution, the same can play a self-priming centrifugal pump maximum value.
