Foreword
This standard is GB/T 13929-1992 "water ring vacuum pump and water ring compressor test" amendments.
This standard compared with GB/T 13929-1992 main changes are as follows.
--- Added "Terms and Definitions" chapter;
--- Test equipment system diagram was perfect;
--- Increasing the stability of the test conditions specified;
--- To vary the amount of repeated measurements of the same reference GB/T 3216-2005 were modified, "the number of reading groups" by an increase in group 9
20 groups, so the use of computer-aided measurement, will help reduce the estimated results from the random effects due to the uncertainty;
--- Increased the pump running tests measuring point specified, and running test of time in terms of drive power a sub-file;
--- Canceled the balance dynamometer measured and calculated as described with reference to the time required to measure the torque can be GB/T 1032-2005 carried out;
--- For gas conversion formula of speed and shaft power conversion factor conversion formulas speed conversion factor with reference to foreign standards were
change;
--- The "Accuracy" to "Measurement uncertainty" into "analysis of the test results" section, and measuring the amount of system uncertainty
Allowable value and total measurement uncertainty acceptable value with reference to GB/T 3216 were modified.
This standard replaces GB/T 13929-1992.
