Mechanical seal centrifugal pump is very important a part in the component, its role is to prevent leakage of medium, improve the work efficiency of centrifugal pump.For conveying special acid alkaline medium and liquid chemical, mechanical seal can prevent more medium leakage caused by the loss and pollution problems.So for the centrifugal pump mechanical seal check, in the daily check of centrifugal pump is more important.The centrifugal pump mechanical seal check includes the following seven points:
1. Check the centrifugal pump mechanical seal inside presence of impurities, such as silt or welding slag, etc.
2. Check what's going on centrifugal pump mechanical seal ring surface scratches, cracks and other defects, these defects exist will cause serious leakage of mechanical seal.
3. Check the action whether defects affect the seal ring.Such as dynamic and static ring seat with dynamic and static ring gasket surface defects such as whether there is a scar.
4. Check whether compensation spring mechanical seal damage and deformation, if stubborn coefficient change.
5. Check the sealing sleeve defects such as the existence of burr, the trench.
6. Cleaning check all gasket exists defects such as cracks, porosity, measurement of synthetic diameter is within the scope of the working poor.
7. Has also check screw pump mechanical seal of pump body of helix whether there is a crack, break the blemish such as.
