Measure and correct for dynamic growth in a Flash. Now, when you add the patented “OL2R” (offline-to-running) hardware+software expansion kit to the revolutionary XA alignment system, you can measure the dynamic movement of critical machines as they reach operating conditions from a cold start. The resulting data is stored in the XA and is readily accessible to automatically adjust future alignments. Onscreen animated graphics make accurate alignments of critical machines fast and easy. Pumping at capacity? 5 19.23% 3 – Within 30% of BEP 5 – More than 30% from BEP 1 – Smooth less than .1 inches/sec 2 – Good, 0.1 to 0.2 in/sec 4 0.62 Vibration analysis 4 15.38% 3 – Fair, 0.2 to 0.3 in/sec 4 – Rough, 0.3 to 0.5 in/sec 5 – Very rough greater than 0.5 in/sec Total asset score 3.46 corresponds to a percentage of the total condition score. Total score rating system tion. See Table 3 for an example. At this point, you should calculate the total score using Eqn 1. Total condition score = ∑(score x weight) .PLANTSERVICES. e next step is to define a set of ratings that describe the overall pump condiO Eqn 1 www.vibralign.com 800-379-2250 Flash is a registered trademark of Adobe Systems Incorporated. 61 http://www.vibralign.com http://www.plantservices.com
