The submersible pump as a submersible equipment for transporting liquid, its main characteristics are a fully enclosed waterproof structure, a liquid-cooled engine design and corrosion-resistant materials of flow components. The frequency of its service depends on the physical characteristics of constant contact with the environment during operation.
Fine particles form a stratification effect on the impeller surface, and substances with high viscosity degrade the grip strength. Soluble minerals are affected by temperature and pressure changes and deposit crystals on mechanical sealing surfaces. Metabolites of bacteria and algae in the bioactive medium easily form a colloidal biofilm in the transfusion chamber.
The accumulation of micron-sized abrasive particles on the rotating surface changes the specific pressure of the end face, and leakage will occur when the lubricating film cannot be completely formed. The bearing preload gradually decreases with the penetration of wear particles, and intervention is necessary before the vibration amplitude reaches the critical point of material resonance. The dynamic balance of the impeller is disrupted by uneven adhesion, which leads to a sharp jump in the radial alternating stress of the shaft.
So how can you predict the best time to clean your Submersible Pump?
Keep track of the progressive trend towards the increase of working current. When the current value continuously exceeds the initial operating base level by a certain fraction, this indicates that deposits on the surface of the super current component have resulted in a significant decrease in hydraulic efficiency. At this time, cleaning can avoid hitting the inflection point of acceleration of wear, restore efficiency and block a deep chain of damage.
