Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 13007-1991 "centrifugal pump efficiency." This standard compared with GB/T 13007-1991, the main technical changes are as follows. --- Added "Normative references" (see Chapter 2); --- Added "Terms and definitions" (see Chapter 3); --- Modify the content of the provisions of the test medium (see 4.1,1991 version 2.1); --- Deleted the word "set point," a number of terms used (see 4.2, 4.3, Example 1, Example 2,1991 version 2.2, 2.3, shows Example 1, Example 2); --- B line modified to allow the pump efficiency in the working range of the lowest point (see 4.3,1991 version 2.3); --- Increasing the calculation example ns = 210 to 300 range of the pump efficiency (see Example 3); --- "Centrifugal pumps and centrifugal corrosion resistant pumps" to "Petrochemical centrifugal pump" (see Chapter 1, Chapter 4, Chapter 5, Figure 3, Table 3, 1991 version of Chapter 1, Chapter 2, Chapter 3, Figure 3, Table 3). The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee pump (SAC/TC211) centralized. This standard was drafted.
