Stress-free inspection of pumps

Thread Content

Regarding the stress-free inspection of pumps: I need to conduct stress-free inspections on some pumps recently, but since I have never carried out such inspections before, I’m a bit confused. I hope someone can explain to me how these inspections are done, as well as what specific parameters and other considerations are involved. The pump I need to inspect is a high-pressure pump, so a GLAYLOC connection is used; this involves the tightness of the connections between the upper and lower flanges, as well as the displacement of the pipelines (I’m not sure if this is the right way to put it). In other words, the distance between the upper and lower flanges (or pipelines) should not be too large, but I’m not clear on what exactly should be used as a standard. When I went for an inspection yesterday, after consulting with a specialist in equipment, it was found that the deviation between one of the upper and lower flanges was 2–3 millimeters, which is not acceptable.
