Question: (DMTO) Olefin separation unit: Purpose of individual compressor testing: (1) To assess the quality of equipment manufacturing, installation, or major repairs; to identify issues in advance and reduce the likelihood of failures after the unit is put into operation ； (2) Test the overspeed protection device to verify its accuracy of operation at the specified maximum speed, in order to ensure the safety of the unit in case of unexpected failures. Note: The answers will be released automatically in two days!
(1) Assess the quality of the manufacturing, installation, or major repairs of testing equipment, identify issues in advance, and reduce the likelihood of failures after the unit is put into operation； (2) Test the overspeed protection device to verify its accuracy of operation at the specified maximum speed, in order to ensure the safety of the unit in case of unexpected failures.
(1) Assess the quality of the manufacturing, installation, or major repairs of testing equipment, identify issues in advance, and reduce the likelihood of failures after the unit is put into operation； (2) Test the overspeed protection device to verify its accuracy of operation at the specified maximum speed, in order to ensure the safety of the unit in case of unexpected failures.
What is the purpose of conducting individual tests on compressors and turbines? Answer: 1. To assess the quality of equipment manufacturing, installation, or major repairs; to identify issues in advance and reduce the likelihood of failures after the units are put into operation together； 2. Conduct experiments on the overspeed protection device to verify its accuracy in operating at specified maximum speeds, thereby ensuring the safety of the unit in the event of unexpected failures.
①① Assess the quality of the manufacturing, installation, or major repairs of testing equipment, identify issues in advance, and reduce the likelihood of failures after the units are put into operation; ② Test the overspeed protection devices to verify their accuracy in responding at specified maximum speeds, thereby ensuring the safety of the units in the event of unexpected failures.
It checks the quality of equipment manufacturing, installation, or major repairs, identifies problems in advance, and reduces the likelihood of failures after the units are put into operation together.

Check whether the mechanical properties of the compressor, as well as its manufacturing and installation quality, meet the specifications and design requirements
1. Check the overspeed protection device. 2. Check the mechanical properties of the motor or turbine. 3. Check the governor and instrument control system
(1) Assess the quality of the manufacturing, installation, or major repairs of testing equipment, identify issues in advance, and reduce the likelihood of failures after the unit is put into operation； (2) Test the overspeed protection device to verify its accuracy of operation at the specified maximum speed, in order to ensure the safety of the unit in case of unexpected failures.
Inspect the overspeed protection device, check the mechanical properties of the turbine, and examine the governor and instrument control system
