GB/T 6490-2021Water-turbine pump (English PDF)

1 Scope

This document specifies the terms, definitions and symbols, types, models and basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage.

This document is applicable to the fields of agricultural irrigation, water supply and drainage, water conservancy and hydropower with a water head of 1m~35m and an overflow of 0.0318m3/s~

13.4m3/s, the head is 2.5m~300m, the water flow is 3.7L/s~4030L/s, and the head ratio is 1~40.

This document includes two levels of measurement accuracy. Level 1 for tests with higher accuracy, Level 2 for tests with lower accuracy,

The two measurement accuracy levels contain different values of tolerance coefficients, allowable fluctuations and measurement uncertainty.

This document applies only to turbo pumps used as water lifts. Other types of turbine pumps can be implemented by reference.
