Methods of testing for water-ring vacuum pumps and compressors
1 Scope
This standard specifies the test methods, analysis and conversion of test results, performance tolerance and test reports in the factory tests for water-ring vacuum pumps and compressors (collectively referred to as pumps ).
This standard is applicable to the tests of pumps of any size with water as working fluid and ambient air as working medium.
This standard applies not only to pumps without any pipeline accessories, but also to pump assemblies connected with all or part of upstream and/or downstream pipeline accessories.
This standard can also be used as a reference when using liquids other than water as working fluid.
