GB/T 10832-2008General specification for centrifigual and vortex pumps of ship (English PDF)

Foreword

This standard replaces GB/T 10832-1989 "centrifugal pump, vortex pump General technical requirements." This standard compared with GB/T 10832-1989, the main technical content of the following changes.

--- To increase the diesel engine, turbine as the prime mover of the chapter;

--- Increased the impeller best efficiency point in the performance curve in the area of \u200b\u200buse;

--- Increased use of environmental requirements extravehicular installed;

--- The balance precision as required by the original standard of Figure 2, is changed to reference the appropriate machinery industry regulations;

--- Original standard vibration test and noise test expression references of national standards;

--- Increasing the fastening bolt, put gas fitting, fixed impeller nuts, shafts, bushings, return pipe, couplings, base and other technical requirements;

--- Pressure casing drilling, thickness and other technical requirements have been added;

--- Increase the technical requirements for operation of the impeller seal ring gap;

--- Modify the reference standard. The standard proposed by China Shipbuilding Industry Corporation. This standard by the China Machinery Standardization Technical Committee Marine deck machinery and auxiliary machinery spaces under the jurisdiction of the Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation seventh - four Institute. The main drafters of this standard. Sun Weiping, Du Yun water, Sun Yuxiang, Li Bing, Gu Qingchun. This standard replaces the standards previously issued as follows:

--- GB/T 10832-1989. Centrifugal pump, vortex pump General technical conditions

1 Scope

GB/T 10832-2008 is the Chinese national standard on general specification for centrifigual and vortex pumps of ship, 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 March 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 September 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 centrifugal pump, vortex pump (hereinafter referred to as. Pump) requirements, test methods, inspection rules, marking, packaging, transport and Storage. This standard applies to ships cooling system, bilge ballast system, circulating water system, fire fighting system, auxiliary boiler feed water system, the water system date And other sea water pump to use, fresh water pump and oil pump design, manufacturing and delivery.
