On mechanical operation tests, performance tests, complete unit tests, and full-load tests for centrifugal compressors

Thread Content

I saw a post earlier discussing tests on centrifugal compressors, so I have compiled several related tests for everyone to discuss: 【What is the difference between performance tests and full-load tests in centrifugal compressors?】 】 No. TEST (Experiment) SUMMARY API 617-2014 8th API 617-2002 7th SH/T 3144-2012 1 Mechanical Running Test Mechanical operation test 1. Required test ； 2. Standalone test ； 3. Use contract meters ； 4. Four-hour full-speed range test (see API 617 Figure 4 for details) ； 5. If there is a spare rotor, the spare rotor also needs to be tested. Part 1 6.3.5 Part 2 6.3.1 Chapter 1 4.3.6 Chapter 2 4.3.1 7.3.4 2 Performance Test (Optional) Performance test (optional) 1. Optional test ； 2. Comply with ASME PTC 10-1997, ISO 5389, or other international standards agreed upon by the buyer ； 3. Type 1 uses the gas test specified in the contract ； Type 2 allows the use of alternative gases for testing ； 4. At least five operating points should be selected (including at least the anti-stall point, the normal operation point, and the endpoint of the curve) ； Part 1 6.3.7.1 Part 2 6.3.3.1 Chapter 1 4.3.8.1 Chapter 2 4.3.3.1 7.3.6.1 3 Complete Unit Test (Optional) Full-system test (optional) 1. Optional test ； 2. Conduct mechanical operation tests with the gearbox, drive unit, and auxiliary and control systems together. 3. It can replace mechanical operation tests. Part 2 6.3.3.2 Chapter 2 4.3.3.2 7.3.6.2 4 Full-pressure/Full-load/Full-speed Test (Optional) Full-pressure/Full-load/Full-speed test (optional) I.1 ASME PTC 10-1997 Part I Tests ； I.1.1 Pertains to fluid property tests ； I.1.2 It falls under single-unit testing, but it is also possible to require a contract-driven motor, a contract oil station, and a contract mechanical seal for overall unit testing ； I.1.3 Use of blended gases is permitted ； I.1.4 At least five operating points shall be selected (including at least the anti-stall point, the normal operation point, and the end point of the curve) ； I.2 Full-load, full-pressure hydrocarbon mixture test ； I.2.1 Pertaining to fluid property tests ； I.2.2 It belongs to a single-unit test, but it is also possible to require a contract-driven machine, a contract oil station, and a contract mechanical seal for a complete-unit test. I.2.3 The test gas is a hydrocarbon mixture ； I.2.4 Only one operating condition is measured. I.3 Full-load, full-pressure inert gas test ； I.3.1 Pertaining to fluid property tests ； I.3.2 It belongs to a single-unit test, but it is also possible to require a contract-driven machine, a contract oil station, and a contract mechanical seal for a complete-machine test. I.3.3 The test gas is an inert gas mixture ； I.3.4 Only one operating condition is measured. I.4 Full-load, full-pressure hydrocarbon mixture test or full-load, full-pressure inert gas test using an excited magnetic suspension bearing Part 1 6.3.7.7 Part 1 Annex I Chapter 1 4.3.8.6 API Std 618-2014 Figure 4 – Mechanical Test
