Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces CJ/T 3038-1995 "submersible sewage pump", compared with the CJ/T 3038-1995 main technical changes are as follows.
--- Increasing the definition of submersible sewage pump (see Chapter 3);
--- Increasing the volume ratio of solid phase in the transport medium (see Chapter 5,.1995 edition 6.2);
--- Increase the submersible sewage pump submerged depth requirements (see Chapter 5);
--- Increasing the performance requirements of over-current components of materials (see 6.2,.1995 version 6.27);
--- Modify the performance requirements of the exposed fastener material (see 6.5,.1995 version 6.27);
--- Improve the motor performance requirements (see 7.2,.1995 version 6.5 and 6.6);
--- Increased motor vibration speed control range requirements (see 7.3.13);
--- Increased surface preparation and painting requirements (see 7.6.3);
--- Increase the average pre-failure time before running the requirements (see 7.3.3,.1995 version 6.23);
--- Modify the test method, regulating the correspondence between requirements and test methods (see Chapter 8 and Table 1,.1995 edition 8
chapter);
--- Increased transportation and storage requirements (see 10.3,10.4);
--- Added Appendix C submersible sewage pump installation diagram (see Appendix C).
