Foreword

This standard replaces GB/T 11034-1989 "marine electric reciprocating pump." This standard compared with GB/T 11034-1989, the main changes are as follows:

--- The nominal flow rate 65m3/h, to the nominal flow rate 63m3/h;

--- Increase the marked sample;

--- Increasing the selection of materials specifications and grades;

--- Increasing the intensity of vibration requirements;

--- Cabin temperature to 50 °C ambient temperature of 5 °C ~ 60 °C;

--- Increasing the medium temperature is 85 °C;

--- Pump noise to. A-weighted sound pressure level should not exceed 85dB, the noise should not exceed the value of the unit of the prime mover or actuator Noise value plus 3dB;

--- The original bearing temperature 70 °C, change should not exceed 75 °C;

--- Cancel the process requirements;

--- Reference standard four additional carry flange standards;

--- Canceled a standard test chart report (Appendix A);

--- Canceled Complete supply range. The standard proposed by China State Shipbuilding Corporation. This standard by the National Standardization Technical Committee of marine deck machinery auxiliary machinery at the Technical Committee and the cabin. This standard was drafted. China Shipbuilding Technology and Economy Research Institute, Benxi water pump limited liability company. The main drafters of this standard. Wang away, Zhao Baodong, Wang Lifang, Cai Zhenzhong. This standard replaces the standards previously issued as follows:

1 Scope

GB/T 11034-2008 is the Chinese national standard on marine electric reciprocating pump, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 3 February 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 August 2008. Classification: ICS 47.020.50, CCS U47. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the marine electric reciprocating pump (hereinafter referred to as the pump) product classification, requirements, test methods, inspection rules, marking, packaging, transportation Transport and storage. This standard applies to transport bilge water, ballast water and fire water and other media pump design, manufacture and acceptance.
