Answer: Newly assembled or overhauled air compressors must be tested before use.
(1) Because during the assembly or overhaul of the air compressor, all the dynamic and static clearances and meshing clearances (such as speed gears and rotor clearances) that match each other are precisely scraped, but their surfaces are still rough and uneven. Therefore, before the air compressor is officially put into production, a test run should be carried out to confirm that the moving surfaces are ground together and fit well.
(2) During the assembly or overhaul of the air compressor, although the mating parts and connecting parts are assembled and adjusted according to quality requirements, there are always some subjective factors in the inspection process. Therefore, there may be some problems hidden in the air compressor, which can be discovered through the test run and eliminated at any time.
(3) Check the operating data of the air compressor to see if it meets the design requirements of the compressor and whether the various protections of the air compressor can act accurately and timely.
(4) Test and confirm the performance and efficiency of the air compressor through the test run.
