What Are The Key Inspection Points For Pump Mechanical Seals

1. Check for impurities inside the mechanical seal of the centrifugal pump, such as mud or welding slag.
2. Check whether there are scratches, cracks, and other defects on the surface of the dynamic and static rings of the centrifugal pump mechanical seal, which can cause serious leakage of the mechanical seal.
3. Check for any defects in the dynamic and static ring seats that may affect the sealing. Whether there are defects such as scratches on the mating surface between the dynamic and static ring seat and the dynamic and static ring sealing rubber ring.
4. Check whether the mechanical seal compensation spring is damaged or deformed, and whether the resistance coefficient has changed.
5. Check the sealing shaft sleeve for defects such as burrs and grooves.
6. Clean and inspect all sealing gaskets for defects such as cracks and air holes, and measure the diameter of the gaskets to ensure it is within the tolerance range.
7. Mechanical seals with pumping mechanisms should also be inspected for defects such as cracks and broken wires in the spiral line of the screw pump.
