Each member body interested in a subject for which a technical committee has been established has the right to be represented on
26、 that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this d

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Direc

This International Standard is not intended to inhibit a supplier from offering
34、, or the purchaser from accepting, alternative equipment or engineering solutions for the individual application. This can be particularly appropriate where there is innovative or developing technology. Where an alternative is offered, the supplier should identify any variations from this Internatio
35、nal Standard and provide details.An asterisk (*) at the beginning of the paragraph of a clause or subclause indicates that either a decision is required or further information is to be provided by the purchaser. This information is indicated on data sheets or stated in the enquiry or purchase order
36、(see examples in Annex A, ISO 10439-2:2015, Annex A, ISO 10439-3:2015, Annex A).This International Standard includes the following annexes: Annex A: Datasheets; Annex B: Vendor (Supplier) data and drawing requirements (VDDR); Annex C: Nomenclature; Annex D: Typical materials; Annex E: Inspectors che
37、cklist; Annex F: Nozzle forces and moments; Annex G: Lubrication and sealing requirements.Annex A forms a normative part of this part of ISO 10439. Annexes B to G are for information only.In this International Standard, where practical, US customary units are included in parentheses for information.

39、, single-shaft, and integrally geared process centrifugal compressors and expander-compressors for special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural gas industries. This part of ISO 10439 specifies requirements for expander-compressors, in addit
40、ion to the general requirements specified in ISO 10439-1:2015.This scope covers only expanders and compressors on a common shaft (expander-compressor). This scope does not apply to expanders with separate output shafts (e.g. generator drives). Hot gas expanders over 300 C (570 F) are not covered in

The compressor
46、shall deliver at least 98 % of the normal head at the normal capacity. The compressor power at the normal condition shall not be more than 106 % of that available from the expander, nor shall it be less than 96 % of that available from the expander.NOTE Compressor-loaded expanders achieve a power ba
47、lance that determines the speed of the machine. There is generally no speed control governor to control the speed the way other turbine-driven compressors are controlled. If the expander power is more than expected, then the speed of the machine will be higher than predicted. If the compressor power
48、 is more than expected, then the speed of the machine will be lower than predicted. The above tolerances are needed to set limits beyond which hardware changes will be required to achieve a reasonable normal speed.4.4.2 The compressor head-capacity characteristic curve at the rated speed shall rise
49、continuously from the rated point to surge. The compressor shall be suitable for continuous operation at any capacity on the predicted performance curve(s) at least 10 % greater than the predicted surge capacity shown in the proposal.NOTE It is common for flow to be bypassed around the compressor during normal operation.4.5 Materials4.5.1 Materials shall be in accordance with ISO 10439-1:2015, 4.5. Refer to Annex D for a table of typical materials.4.5.2 If traces of mercury have been specified, aluminium impellers shall be treated
