--- Modify the environmental conditions;

--- Altered the noise, vibration, shock and net absorption height of test requirements. The standard proposed by China Shipbuilding Industry 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 Industry Corporation seventh - four Institute. The main drafters of this standard. Nie Shubin, LU Wei collar, Alan Li days, Xue Hongjun. This standard replaces the standards previously issued as follows:

--- GB/T 11035-1989. Marine electric twin-screw pump

1 Scope

GB/T 11035-2008 is the Chinese national standard on marine electric two spindle screw 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 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 47.020.30, 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 double screw pump (hereinafter referred to as the pump) product classification, technical requirements, test methods, inspection rules, marks, Packaging, transport and storage. This standard applies to the ship used oil pump, fuel pump, fuel injection pump boiler, cargo pumps, water supply pumps, fire pumps, drainage pumps, ballast Pump design pumps, sanitary pumps and chemical pumps and other transportation twin screw spiral line formed, production, testing and acceptance.
