GB/T 14541-2017Guide for maintenance and supervision of in-service mineral turbine oil used for power plants (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 14541-2005 "Guidelines for the Management of Mineral Steam Turbine Oil for Power Plant Operation", and GB/T 14541-2005 In addition to editorial changes, the main technical changes are as follows.

--- modified the name and scope of the standard, the turbine oil modified to turbine oil;

- in the normative reference file, increase or decrease the reference file;

--- removed the text of the "turbine oil operating life of the factors and the severity of turbine oil", this part of the content moved to Recorded --- increase the performance of turbine oil;

--- to modify the new oil acceptance of rotating oxygen bomb quality indicators;

--- increase the acceptance of new oil should be tested when the project;

--- to modify the quality of oil and oil test cycle;

--- modified the requirements for the replenishment;

--- increased demand for oil change;

--- modified the contents of the oil treatment and additives for the maintenance of turbo oil;

- Removed Appendix C Lubricant Oxidation Stability Assay (Rotational Oxygen Act).

1 Scope

This standard specifies the maintenance and management of mineral turbine turbines for power plant steam turbines, turbines and gas turbine systems for lubrication and speed regulation.

Cameras and feed pumps and other auxiliary equipment used in the maintenance and management of mineral turbine oil can also refer to the implementation.

This standard applies to the maintenance and management of mineral turbine turbines for power plant steam turbines, turbines and gas turbine systems for lubrication and speed regulation.

This standard does not apply to a variety of non-mineral synthetic liquids for turbine lubrication and speed regulation.
