CJ/T 518-2017Submersible axial-flow pump (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009 and GB/T.20001.10-2014.

This standard is a revision of CJ/T 3060-1996 Submersible Axial Flow Pump. Compared with CJ/T 3060-1996, the main technical changes are as follows.

--- Expands the scope of application of pump flow and power (see Chapter 1, Chapter 1 of the 1996 edition);

--- Increased non-coaxial planetary gear transmission structure (see 4.1.2);

--- Increased pump performance parameters, increased 660V, 3kV, 6kV and 10kV high voltage (see 5.2);

--- Modify the motor electrical performance guaranteed value and tolerance (see 7.3.3, 1996 version 7.6.6);

---Modified the inter-turn insulation test of motor forming windings, and the requirements and tests for the withstand voltage level of stator coils (see 7.3.10, 1996 edition of 7.8, 7.10);

--- Increased the pump outlet cable voltage when the voltage is greater than 660V (see 7.3.9);

--- Modify the noise requirements of the pump when no load (see 7.3.11, 1996 version 7.25);

--- Increased vibration requirements at pump no-load (see 7.3.12);

--- Increased processing and assembly requirements (see 7.5);

--- Increased rust and paint requirements (see 7.6);

--- Increased safety requirements (see 7.7);

---Prolonged the average pump failure-free working time (see 7.8, 7.23 of the 1996 edition);

--- Refined test method provisions (see Chapter 9 and Table 1, Chapter 8 of the 1996 edition);

--- Increased storage requirements (see 10.4).

This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards.

This standard is under the jurisdiction of the Municipal Water Supply and Drainage Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.
