GB/T 14211-2019Test method of mechanical seal (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14211-2010 "Mechanical Seal Test Method". This standard is compared with GB/T 14211-2010, except for editing The main technical changes outside the sexual modification are as follows:

--- Added normative references (see Chapter 2);

--- The factory test has increased the air tightness test (see 4.1.2, 4.2);

--- Increased the type of test media (see Table 1, Table 2,

4.1 of.2010 edition);

--- The test method is subdivided according to the sealing arrangement and the transport medium (see Chapter 4, Chapter 5, Chapter 3 of the.2010 edition);

--- Removed the contents of the appendix mechanical seal test report (see Appendix A of the.2010 edition). This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Mechanical Sealing Standardization Technical Committee (SAC/TC491). This standard was drafted.

1 Scope

GB/T 14211-2019 is the Chinese national standard on test method of mechanical seal, in the field of mechanical systems and components. 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 18 October 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 September 2020. Classification: ICS 21.140, CCS J22. 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 test classification, factory test, type test, test report, test device and instrument for mechanical seal product performance test. Meters, etc. This standard applies to mechanical seals of centrifugal pumps and similar rotating machinery.
