Ships and marine technology - Maintenance and testing for reducing losses in critical systems for propulsion ICS 47.020.20 U47 National Standards of People's Republic of China Ship and marine technology to reduce the key to push the ship Maintenance and testing of system loss (ISO 13613..2011, IDT) 2016-12-13 released 2017-07-01 implementation General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China China National Standardization Management Committee released

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the translation method equivalent to ISO 13613..2011 "Ship and marine technology to reduce the ship to promote the key system of the loss of the dimension Care and test ". This standard is proposed by China Shipbuilding Industry Corporation. This standard by the National Marine Machinery Standardization Technical Committee (SAC/TC137) centralized. The drafting unit of this standard. China Shipbuilding Industry Comprehensive Technology and Economic Research Institute, Henan Diesel Heavy Industries Co., Ltd., Harbin Engineering the University. The main drafters of this standard. Sun Meng, Song Enzhe, Ji Yonghui. Ship and marine technology to reduce the key to push the ship Maintenance and testing of system loss

1 Scope

This standard specifies the overall maintenance and test methods for the ship propulsion critical system (hereinafter referred to as the system), including compressed air systems, Fuel systems, automation systems and so on. This standard applies to the crew of the ship system maintenance, but also for the relevant departments to provide ship system operation and maintenance and testing of technical information and Suggest.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Differential pressure Δp The pressure difference between the two points of the system is used to measure the measurement parameters of the filter state (cleaning or clogging). 2.2 Viscosity A measure of the flow resistance of the liquid. Note. Fuel viscosity includes minimum viscosity and maximum viscosity, through the fuel viscosity, can determine the fuel flow, the degree of atomization and the appropriate atomization temperature.

3 request

3.1 overall system maintenance The overall maintenance of the ship system is to improve system efficiency and reliability and reduce downtime. Appropriate maintenance intervals will help avoid Free equipment failure. 3.1.1 Maintenance type 3.1.1.1 Plan maintenance Scheduled maintenance includes routine inspection and planned inspections. a) routine inspection Routine inspections include the following. --- oil leakage, lubrication, liquid level inspection (oil tank, fuel tank); --- operation check (button/switch, valve/board, lamp, alarm); --- measurement (size, gap, voltage, pressure, temperature, vacuum). b) plan check The plan includes the following items. --- cycle check (week, month, quarter, year, etc); ...
