Repair plan for corrosion, erosion and wear of pulp pumps

The wear and corrosion problem of the pulp pump in the papermaking production process of the English paper pulp pump is a common occurrence. The traditional treatment methods for pump body wear and tear usually use the following methods:

① Partial repair welding: In the papermaking industry, stainless steel is usually used for repair welding of worn parts of pump bodies. Due to different materials, bimetallic corrosion occurs during use after welding, and the repair effect is not ideal.

② Replacing worn parts: Generally, only the rotor and impeller parts are replaced, and the pump body is difficult to achieve due to limitations such as cost.

③ Changing the material: By changing the material of the pump, the problem of wear and corrosion has been solved, but it cannot fundamentally solve this problem while increasing costs. The repair process is simple: (1) surface treatment; (2) Coat the surface of SD carbon nano polymer material (3) for surface finishing, and the material can be cured and turned on.
