Centrifugal pump alignment
Thread Content
What methods do you use for double-gauge alignment of your centrifugal pumps?
I don’t quite understand what you mean. With two tables, one is aligned axially and the other radially; after rotation, one observes the general trend and then makes gradual adjustments.
Using a saw blade for alignment – have you seen that?~~~
Seen them: sledgehammer, crowbar, used steel ruler
Tools include hammers, copper sheets of various sizes up to 1 millimeter thick, copper bars for use during striking, and crowbars. Flat wrenches and adjustable wrenches.
I’m very grateful to the friend above for providing a detailed and evidence-based answer. By the way, I took a look – the standards for screenshots have been updated; it’s SH3538-2017, the General Specifications for the Construction and Acceptance of Petrochemical Machinery and Equipment Installation Projects
I’ve also seen people use steel rulers or similar tools to level things out; of course, it’s not very accurate
It depends on what type of coupling is used! In the case of a plum blossom pad buffer coupling, the alignment requirements are not high; what was mentioned by someone upstairs about aligning the saw blade is quite normal. The tools required are adjustable wrenches, shims, or fine-tuning copper sheets. In the case of diaphragm couplings, high precision is required for alignment; it is generally necessary to use gauges for measurement, both axially and radially. This is especially true for magnetic pumps, where even higher standards of alignment are required – careful measurement using gauges is essential to ensure that the alignment values remain within the specified technical limits
