Regarding the issue of the centrifugal pump shaft being exposed to light
Thread Content
As the title suggests, in equipment management, there are three requirements: ensure the bottom of the groove is visible, ensure the shaft is visible, and ensure the equipment shows its true color. What methods can be used to maintain the shaft in good condition after it has been polished? So it’s in good condition? ?
This is the standard: cleaning must be thorough, and there are standards for checking the cleanliness of equipment; as long as there is no oil on the shafts and everything is clean, that’s sufficient
The so-called \"axis seeing light\" does not actually mean seeing light; it is sufficient as long as there is no oil contamination on the axis and it remains clean. It is in line with equipment management requirements for some shafts to rust during use.
After grinding the journal, a coat of alkyd varnish (polish) can be applied to prevent rusting, and this protection will last for a long time!
Apply anti-corrosion oil, seal with kraft paper, and this will prevent oxidation.
But over time, the varnish turns yellow, which is not aesthetically pleasing
Wipe it every day – what else can you do? The equipment standards are strict; wipe it thoroughly
By \"keeping the shaft clean,\" it doesn’t necessarily mean that the shaft has to be made extremely shiny or even polished to perfection; it is simply one of the most basic requirements in equipment maintenance – as long as the equipment remains clean, that’s sufficient. Of course, if the equipment is not in use or is sent for processing elsewhere, it’s necessary to protect the shaft; generally, applying oil and covering it with rubber is sufficient, with anti-corrosion oil being used for the oil application
Just wipe it more often. . . . . . . . . . . . .
