Mechanical sealing leakage reasons and solution
1、multistage pumps insufficient spring pressure?
Solution: adjusting spring compression value or changing the spring
2、the multistage pumps dynamic ring or static ring corrosion, wear, or scratch?
Solution: repair or replace bad dynamic ring, static ring
3、multistage pumps fixed screw looses, makes spring out of action?
Solution: tighten screws or re-adjust spring
4、multistage pumps dynamic ring sealing ring assembly inclined coil or corrosive deformation?
Solution: reinstall or replace river pump used dynamic ring sealing ring
5、multistage pumps static ring skewed assembly?
Solution: reinstall river pump used static ring
6、multistage pump shaft sleeve process precision and glossiness is not enough, influening dynamic ring axial movement.
solution: replace process precision qualified shaft sleeve.
7、Multistage pump impurities, foreign matter, or medium crystallization affects the dynamic ring axial moving or support between dynamic and static ring ends?
solution: elimate impurity, foreign matter, and crystallization, thoroughly clean the sealing components.
