Submersible pump common fault analysis and solution

[Asia Fluid Network News] submersible pump unit by: pumps, submersible motor water pipes and control switch composed of four parts. Due to its increasing use, more and more people noticed a more realistic problem, that is, the submersible pump failure analysis. Because each product is bound to have its own shortcomings and deficiencies, research and analysis of these situations can provide a favorable guarantee for the improvement and improvement of products. Submersible pump and then the main analysis of common failures and solutions: Analysis and solutions to common submersible pump failure 1, no water or intermittent water, less water: Solution: ① motor is not started to troubleshoot the circuit; ② pipeline blocked, clear Blockage; ③ pipeline rupture, repair welding or tube change; 2, the motor can not be started, accompanied by buzz: Solution: ① one phase circuit, repair lines; ② axle bearing, repair or replacement; 3, the current is too large, the ammeter pointer swing: Solution: ① rotor sweep bore, replace the guide bearing; ② relative rotation of the shaft and the bearing is not flexible, replace or repair the bearing; ③ due to thrust Bearing wear and tear, leaf rotation and seal ring phase, replace the thrust bearing or thrust plate; 4, motor winding insulation resistance to ground low: Solution: motor windings and cable joints or cable damage, replace the winding, repair joints or cable. 5, the unit running violent vibration: Solution: ① motor rotor imbalance, in addition to bolt loose can be fastened, the rest of the fault sent to the manufacturer; ② pump impeller imbalance; ③ motor or pump shaft bending; through the above analysis We can understand that submersible pumps are also prone to failure at work, but there are ways to deal with it. For customers, a product does not mind the existence of the product itself, but the problem does not correspond to the treatment. For concentrated pump, it has many problems, but it is delightful that these problems are there can be a corresponding solution. For the future development, concentrate on the pump need to face a lot of difficulties, I believe that in all sectors of the continuous efforts, devote themselves to pump the future will be brilliant.
