Acoem’s Falcon<\/a> (vibration data collector\/analyzer) uses Accurex\u2122 automatic diagnostic software to determine vibration problems in rotating equipment. Accurex\u2122 performs first-order diagnostics based on specifications. ISO 10816-3<\/a> (based on general vibration levels in velocity, in inches per second\/peak or mm\/sec\/rms) and a second-order diagnostic based on several thousand rules. algorithms.<\/p>\n

<\/p>\n

To help new users understand the ISO 10816-3 chart, let’s break it down. All machines within this specification operate at speeds between 120 and 15 000 rpm.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Group 2 Machines:<\/strong>  electric motors and driven machines between 20 and 402 hp.<\/p>\n

<\/p>\n

Group 1 machines:<\/strong> electric motors and driven machines above 402 hp.<\/p>\n

<\/p>\n

You will notice in the graph that Group 1 machines can tolerate slightly higher vibration levels than Group 2 machines. This is because larger machines have a larger mass, a wider stance and can generally tolerate slightly higher overall vibration levels.<\/p>\n

<\/p>\n

Each of these two groups is also separated into rigid and flexible mounts.  Machines mounted on a flexible base, such as isolator springs or neoprene pads, can tolerate slightly higher vibration levels, as the movements of these machines are damped or damped by the isolator or pad.<\/p>\n

<\/p>\n

Let’s take as an example a 150 hp electric motor, driving a pump, at 1765 rpm, on a rigid base, and use the ISO 10816-3 table.<\/p>\n
