GB/T 17189-2017Code for field measurement of vibrations and pulsations in hydraulic machines (turbines, storage pumps and pump-turbines) (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 17189-2007 "hydraulic machinery (turbines, storage pumps and pump turbines) vibration and pulsation field test gauge Cheng ", compared with GB/T 17189-2007 main technical changes are as follows.

--- Modify the vibration measurement site and measuring point arrangement (see 6.2.2, 2007 edition of 6.2.1);

--- Revised the measurement of pressure pulsations and measuring point arrangement (see 6.2.4, 2007 version 6.2.3);

--- Vibration measurement frequency range has been adjusted, see Table 1 and Table 2. For the purpose of special diagnostic tests, should be selected on request Select the measurement equipment (such as Karman vortex caused by resonance, the frequency of the upper limit will exceed the frequency range specified above, should choose a higher frequency Upper limit of the sensor) (see 7.2.1 and 7.3, 2007 edition of 7.2.1 and 7.3);

--- Pressure pulse sensor installation has been adjusted from the original "after the probe should be flush with the inner wall of the runway," revised to "should the use of sensor probe flush with the inner wall of the flow channel to install the sensor, the sensor should be easy to disassemble. When conditions do not have Under the short straight tube leads to "(see 7.4.2, 2007 version 7.4.1.5);

--- A chapter on signal recording was revised to delete the original standard "graphics recorder" and "tape recorder" two sections, the original the "Digital Recorder" section of the standard has been refined and supplemented to form a new chapter for measurement data acquisition (see Chapter 9, 2007 edition of Chapter 9);

--- Modify the vibration and pulsation test peak-peak mixing amplitude value of the method (see 10.2.1).

This standard adopts the redrafted law to amend the use of IEC 60994:1991 "hydraulic machinery (water turbines, storage pumps and pump turbines) vibration and pulsating field measurement guidelines. " this standard compared with IEC 60994:1991 in the structure there are more adjustments, Appendix A lists the standards and IEC 60994:1991 Chapter number control list.

This standard compared with IEC 60994:1991 there are technical differences, Appendix B gives the corresponding technical differences and their causes Table.

This standard proposed by the China Electrical Equipment Industry Association.

This standard by the National Standardization Technical Committee turbine (SAC/TC175) centralized.
