Submersible pumps often leak due to aging or wear of the sealing device. In addition to replacing the seal, there are several simple methods you can try to fix the issue. First, if the seal has lost its elasticity after long-term use, remove the old seal and cut a piece of paper or cloth (0.3–3.5 mm thick) into a shape slightly larger than the original gasket. Insert this material into the groove before re-installing the original seal. This temporary fix can help restore some sealing effectiveness.
Second, if the nylon seal seat inside the rubber seal is worn, you can remove the seal and reposition it in a different location. If the spring that holds the sealing ring becomes weak or breaks, take out the spring and replace it with a wire of suitable diameter, then tighten it properly.
Third, if the first ring is severely worn, remove the nylon ring and apply asbestos-based grease. Wrap it with a thin stainless steel sheet that's slightly taller than the original nylon seat, then fill the space with more grease. Finally, secure the nylon seat with a bolt to compress it back into place.
Fourth, if the seal box and cast iron seal lose their elasticity, take out the seal and cut a piece of cardboard (6–10 mm thick) to fit the size of the tank. Place it inside the cast iron housing and re-install the seal. This helps maintain the proper compression.
Fifth, if the rubber ring around the oil hole is damaged, take a piece of tape, cut a hole slightly larger than the bolt, and place it along with a flat washer over the bolt before inserting it into the hole. This can help prevent further leakage.
These methods are practical and cost-effective solutions for minor leaks, allowing you to extend the life of your submersible pump without immediate replacement. Always make sure to test the pump after repairs to ensure the problem is resolved.
Antibacterial powder coatings are widely used in medical equipment, food processing equipment, public places, sanitary facilities, and other places and equipment that require cleanliness and hygiene to be maintained.
Their advantages include long-lasting antibacterial effects, resistance to the influence of cleaning agents and disinfectants, as well as being friendly to both human health and the environment.
The use of antibacterial powder coatings can effectively reduce the risk of bacterial transmission, ensuring people's health and safety.
Antibacterial powder coating is a special type of powder coating that has the function of inhibiting bacterial growth.
This type of coating typically contains antibacterial agents, which can form a protective antibacterial layer after the coating is cured, effectively inhibiting the reproduction and spread of bacteria.
