Abstract
A method for removing incrustation on the inner wall of a copper pipe of a diffusion pump is characterized in that the inner wall of the pipe is immersed in hydrochloric acid with the concentration of 6%-8% for more than six hours, and the incrustation on the inner wall of the copper pipe can be effectively removed. The method has the beneficial effects of being simple, practical and low in cost, by means of treatment, more cost is reduced for an enterprise, production benefits are greatly increased, and more time is saved for maintenance personnel.
Description
Technical field
The invention belongs to diffusion pump cooling copper tube and dispel inside pipe wall incrustation scale method.
Technical background
In electronic torch melting process, the function of diffusion pump is very important, its use concerns stove and can be evacuated to high vacuum, but in using for a long time, owing to containing various element impurity in factory's cooling water, diffusion pump cooling copper tube inwall there will be incrustation scale unavoidably, causes discharge in copper pipe to reduce even to block, have impact on the cooling effect of diffusion pump, thus have impact on the normal use of diffusion pump.
Summary of the invention
Object of the present invention provides a kind of method effectively dispelling diffusion pump copper pipe inwall incrustation scale to overcome the defect of above-mentioned prior art existence just.Because the composition of scale of diffusion pump cooling copper tube inwall is in alkalescence, the present invention effectively can dispel the incrustation scale of copper pipe inwall in the salt acid soak more than 6 hours that inside pipe wall employing concentration is 6% ~ 8%.Because low-concentration hcl effectively can dispel copper pipe inwall incrustation scale, and don't copper pipe can be damaged.
The beneficial effect of the inventive method is, simple and practical, and cost is low, after this process, for enterprise has saved more costs, allows productivity effect greatly increase, has also saved the more time to attendant.
Detailed description of the invention
Embodiment one
Because copper pipe exists the drop of high in and low out, the water pipe of one about one meter length is adopted to be connected to diffusion pump copper pipe upper end, then pour into (re-using if the hydrochloric acid high less than usable concentration is diluted with water to 6%) with the hydrochloric acid of 6%, when hydrochloric acid stream exports to copper pipe, block with plastics.After 8 hours, the hydrochloric acid of copper pipe inwall and impurity are gone out in water flowing, and this just can effectively dispel pipe inner wall incrustation scale.
Embodiment two
Because copper pipe exists the drop of high in and low out, adopt the water pipe of one about one meter length to be connected to diffusion pump copper pipe upper end, then pour into (if the hydrochloric acid high less than usable concentration is diluted with water to 7%, re-using) with the hydrochloric acid of 7%, when hydrochloric acid stream exports to copper pipe, block with plastics.After 6 hours, the hydrochloric acid of copper pipe inwall and impurity are gone out in water flowing, and this just can effectively dispel pipe inner wall incrustation scale.
Embodiment three
Because copper pipe exists the drop of high in and low out, (one about one meter length) water pipe is adopted to be connected to diffusion pump copper pipe upper end, then pour into (if the hydrochloric acid high less than usable concentration is diluted with water to 7% with the hydrochloric acid of 8%, re-use), when hydrochloric acid stream exports to copper pipe, block with plastics.After 7 hours, the hydrochloric acid of copper pipe inwall and impurity are gone out in water flowing, and this just can effectively dispel pipe inner wall incrustation scale.
Claims (1)
1. dispel a method for diffusion pump copper pipe inwall incrustation scale, it is characterized in that, inside pipe wall adopt concentration be 6% ~ 8% salt acid soak more than 6 hours effectively can dispel the incrustation scale of copper pipe inwall.
