Method for quickly repairing corrosion and erosion of pump shell of desulfurization pump on site

Abstract

The invention relates to the technical field of mechanical maintenance, and particularly discloses a method for quickly repairing corrosion and erosion of a pump shell of a desulfurization pump on site. 2) treating the inner surface of the pump shell; (3) after sand blasting is completed, absolute ethyl alcohol is used for cleaning the inner surface of the whole pump shell; 4) strictly blending the material A according to the proportion, and uniformly brushing the material A to the inner surface of the pump shell; 5) strictly blending the material B according to the proportion, and then uniformly smearing the material B on the surface of the material A; (6) after smearing is completed, a scraping plate is adopted for repeated scraping and pressing, and the surface is more compact and smoother; (7) the compactness of the surface is checked, and local defects are repaired for the second time so that the surface of the whole protective layer can be free of defects; according to the method for rapidly repairing the corrosion and erosion faults of the pump shell of the desulfurization pump on site, the corrosion and erosion faults of the pump shell of the desulfurization pump can be rapidly repaired on site, the used materials are good in abrasion resistance and short in repairing time, and the maintenance cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical maintenance, in particular to a method for quickly repairing corrosion and erosion of a pump casing of a desulfurization pump on site. Background technique [0002] In the desulfurization pump, sulfur-containing acid solution often washes the inner surface of the pump casing, causing erosion and corrosion on the inner surface of the pump casing, affecting the service life of the desulfurization pump, and the cost of replacement is high, resulting in waste of resources. It takes a long time to affect production efficiency. Therefore, the inner surface of the desulfurization pump is generally repaired. The traditional technology includes: repair welding machine processing, electric brushing, laser cladding, etc., but the depth of corrosion erosion on the surface is limited, the repair period is long, and the price is expensive. There are issues affecting production. Therefore, there is an urg...

AI Technical Summary

Problems solved by technology

[0002] In the desulfurization pump, sulfur-containing acid solution often washes the inner surface of the pump casing, causing erosion and corrosion on the inner surface of the pump casing, affecting the service life of the desulfurization pump, and the cost of replacement is high, resulting in waste of resources. Long time, affecting production efficiency

Therefore, the inner surface of the desulfurization pump is generally repaired. The traditional technology includes: repair welding machine processing, electric brushing, laser cladding, etc., but the depth of corrosion erosion on the surface is limited, the repair period is long, and the price is expensive. There is a problem affecting production

Therefore, there is an urgent need to design a method for quickly repairing the corrosion and erosion of the desulfurization pump casing on site to solve the problems of insufficient repair depth, long repair period and high cost of the existing desulfurization pump casing repair methods
