3 performance rating evaluation index

This standard determines the performance level of the pump by checking the specified flow rate of the pump, stipulating the head and pump efficiency. The performance rating of the pump is divided into 1, 2, 3 Three grades, one level indicates the highest pump performance. The evaluation index of each performance grade shall meet the requirements of Table 1. Table 1 Performance level Specifies the flow rate of the lift pump efficiency Grade 1 QG (1 5%) HG (1 3%) ηSP 3.0 Grade 2 QG (1 ± 5%) HG (1 ± 3%) ηSP 1.0 3 QG (1 ± 8%) HG (1 ± 5%) ηSP-Δη In the table, ηSP is the pump efficiency value specified in GB/T 24673 and the tolerance is not satisfied. The pump efficiency tolerance Δη shall comply with the provisions of GB/T 24673. QG, HG points Do not specify the required flow rate for the pump in GB/T 24673 and specify the head value and no tolerance. The specified head value HG of the pump is allowed to be in accordance with the provisions of GB/T 24673 Amendment.

4 other requirements

The pump type, other basic parameters and technical requirements shall comply with the provisions of GB/T 24673. ......
