The cooling system of vertical oil-free vacuum pumps often suffers from poor cooling performance due to the use of river water, and may even get clogged by silt. Cleaning is rather troublesome; the company usually relies on water flushing to dispose of the waste through the drainage outlet, but the effect is not significant. Today, I used compressed air by introducing it at the return water inlet and discharging it from the waste water outlet; the effect was quite noticeable, as all the dark water and sediment were washed out. Repeat several times until no black water or sludge comes out. Although there are dead corners, silt may still remain. Then send it over and rinse it a few times; it can basically be completely cleaned. The workshop staff said that this long-standing problem was solved in this way – using compressed air for cleaning and flushing is simple and effective.
