1 Scope

This standard specifies the vibration measurement, measuring instruments and pump vibration evaluation method in the non-rotating parts of the surface of the pump carried out.

This standard applies to speed 600r/min ~ 12000r/min (less than 600r/min can refer to the use) of various types of pumps, pump

Total motor shaft (or shaft and motor shaft rigid coupling connection) of the pump unit.

This standard does not apply to submerged pump, reciprocating positive displacement pumps and internal combustion engine driven pump units.

3 Terms and Definitions

GB/T 7021 and GB/T 2298 defined by the following terms and definitions apply to this document.

3.1 Vibration intensity

Such as a maximum value, a mean value or set of values, or other descriptor rms vibration parameters, involving multiple transients or more plane

Mean.

Note 1. The vibration intensity is a generic term that is often used in the past when it comes to vibration velocity. Now, however, other more for measuring the amount of displacement, acceleration and the like.

Note 2. The mechanical vibration intensity is defined as the point in a number of different machines such as shafts, the maximum value of the other components of the measured amount of bearing vibration or mechanical structure.

Note 3. The duration of the vibration is sometimes included in the description of the vibration intensity parameter, but this usage is not in favor of use.

4 Measurement

4.1 Measurement parameters

4.1.1 The measurement frequency range

In order to fully cover the pump spectrum, vibration measurements should be selected broadband frequency range is typically 10Hz ~ 1kHz.

4.1.2 vibration value

Made in line with GB/T 13824 requirements specified measuring instruments to measure results is called the position and vibration direction.
