Abstract
The present invention relates to a kind of method for repairing and mending of pump case, comprising the following steps: (1) removes antifouling paint, rusty stain or the washmarking on surface；(2) it polishes the sealing at position to be repaired, grinds off the concave-convex iron pimple on pump case surface, be allowed to surfacing until exposing pump case ontology；(3) it Bonded Repair plate and anchors；(4) sandblasting roughening is carried out to pump case skin patching position；(5) pump case surface acetone and ethanol washing after being roughened sandblasting, it is dry；(6) preservative treatment is carried out.The present invention can prevent the corrosion between casing ring and shell；Leakage caused by preventing because of corrosion between casing ring and shell.
Description
Technical field
The present invention relates to the manufacturing technology field of pump, in particular to a kind of method for repairing and mending of pump case.
Background technique
Pump case is exposed for a long time to expose to the sun and rain outside, is also easy to produce erosion, and produce sometimes around casing ring
Anger erosion, cavitation erosion meeting attack metal material, therefore sometimes include the position that casing ring is contacted with shell, shell in its vicinity
Body surface face generates erosion.Especially, in the widely used cast iron of the material of pump, this dissimilar metals contact corrosion is gentle
The surface damage that erosion is corroded when being superimposed is significant.If such leakage increase and shell damage aggravation, become larger and are unable to satisfy pump institute
It is required that performance.Moreover, the strength reduction of pump case, generating a possibility that more massive pump breakage and improving.
Summary of the invention
The purpose of the present invention is overcoming defect of the existing technology, providing one kind is prevented between casing ring and shell
Corrosion；The method for repairing and mending of the pump case of leakage caused by preventing because of corrosion between casing ring and shell.
Realizing the technical solution of the object of the invention is: a kind of method for repairing and mending of pump case, comprising the following steps:
(1) antifouling paint, rusty stain or the washmarking on surface are removed；
(2) it polishes the sealing at position to be repaired, grinds off the concave-convex iron pimple on pump case surface, until exposing pump case ontology
It is allowed to surfacing；
(3) it Bonded Repair plate and anchors；
(4) sandblasting roughening is carried out to pump case skin patching position；
(5) pump case surface acetone and ethanol washing after being roughened sandblasting, it is dry；
(6) preservative treatment is carried out.
After the pressing plate repaired and screw surface are specially derusted and are cleaned by above-mentioned technical proposal step (6),
One layer of asphalt caulk is coated, for preventing surface corrosion.
After adopting the above technical scheme, the present invention have the effect of it is following positive: the present invention can prevent casing ring
Corrosion between shell；Leakage caused by preventing because of corrosion between casing ring and shell.
Specific embodiment
(embodiment 1)
The present invention is a kind of method for repairing and mending of pump case, comprising the following steps:
(1) antifouling paint, rusty stain or the washmarking on surface are removed；
(2) it polishes the sealing at position to be repaired, grinds off the concave-convex iron pimple on pump case surface, until exposing pump case ontology
It is allowed to surfacing；
(3) it Bonded Repair plate and anchors；
(4) sandblasting roughening is carried out to pump case skin patching position；
(5) pump case surface acetone and ethanol washing after being roughened sandblasting, it is dry；
(6) preservative treatment is carried out.
Step (6) is specially after the pressing plate repaired and screw surface are derusted and cleaned, to coat one layer of pitch
Paint, for preventing surface corrosion.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in guarantor of the invention
Within the scope of shield.
Claims (2)
