Introduction
Rotary power pump vibration measurements has many uses, such as for operational monitoring, acceptance testing and diagnostic studies (condition monitoring) analysis. suitable
Coupling theory for industrial machinery vibration measurement and assessment in GB/T 6075.1 (vibration on non-rotating parts) and ISO 7919-1 (Off
The shaft vibration) to do the general explained.
This section is based on collecting a lot of data on the operation of the pump vibration, the survey covers a variety of on-site testing facilities and on about
1,500 different types of speed and power, running over a wide flow range of the pump. Despite the lack of vibration measurements and the average operating life on the pump
Information life relationship, but due to the large amount of data, the data provided in this section can be considered well-pump representatives.
The statistical evaluation of these data and the corresponding flow and power as the optimum working range of 70% to 120% ie the best efficiency point.
Vibration survey shows whether the pump is a rigid support or flexible support, whether in horizontal or vertical direction of the pump, as long as this section
Measuring a predetermined position on no significant differences. This section presents the measurement of vibration and other vibration measurement standards do exist are not involved
Same place.
Statistical analysis showed that the value of the vibration of the pump power consumed by a certain degree of correlation, so this section will pump into 200kW or less, and
200kW more than two levels.

Rotary power pump (including measurements on rotating shafts)
1 Scope
GB/T 6075 This section describes the evaluation of rotational vibration in industrial applications rated power greater than 1kW power pump, provides non
Specific requirements for measurement and evaluation of vibration on rotating parts (bearing) is provided on site or in the factory runtime and manufacturer test facility progress
Measurement Evaluation Guide for specific rotary power pump bearing vibration intensity when the line of acceptance tests. This section also gives the evaluation of the axis of rotation relative to the shaft vibration
Fixed general information and guidance.
This section provides vertical and horizontal pumps pump vibration area and limits regardless of their support rigidity. These both general evaluation criteria
Operational monitoring applies rotational power pump, also suitable for acceptance testing on site or manufacturer test facility 1). For Manufacturing
Acceptance tests performed on the facility's test, this section gives a special request.
For the whole vibration monitoring long-term operation of the machine, this section gives the two criteria to evaluate the vibration. Guidelines have taken a measured vibration
Moving the magnitude of the other criteria into account changes in magnitude. These evaluation criteria applied to the vibration generated by the pump itself, does not involve the transfer by a pump outside
Vibration. These guidelines ensure that the pump is mainly used for reliable, secure, long-term operation, while its harmful effects on the equipment connected to the minimum.
In addition, this section also gives a predetermined operational limits and setting alarm and shutdown value proposal.
For the integrated motor (impeller mounted on the motor shaft or impeller shaft rigidly connected with the motor shaft) of the pump, this section apply to the entire coupling
Combined pump.
For flexible connection of the motor pump, this section applies only to the pump body. This section does not involve the driver installed separately, these driver
Involved in the ISO 10816-3.
The following types of pumps do not belong to the scope of this section.
--- Reciprocating and rotary positive displacement pump;
--- Reciprocating engine driven pump;
Pump --- hydroelectric plants and pumping stations in a power greater than 1MW (reference standard ISO 7919-5 [4] and ISO 10816-5);
--- Solids handling pumps, mud pumps and submersible pumps.
This section does not involve torsional vibration.
