[0002] Newly assembled or overhauled air compressors must be tested before use. During the assembly or overhaul process, all the dynamic and static clearances and meshing clearances (such as speed gears and rotor clearances) of the air compressor are precisely scraped, but their surfaces are still rough and uneven. Therefore, before the compressor is officially put into production, a test run should be carried out to confirm that the moving surfaces are well ground and matched.

[0003] In the prior art, there are many types of air compressors in factories, and the main air compressors and some maintenance and modification units also need to be tested in the factory. The test bench in the factory only has a starting cabinet, and the air compressor test data (volumetric flow, power, current, vibration, noise, etc.) and the internal test data of the air compressor (exhaust temperature, exhaust pressure, main motor stator temperature, main motor bearing temperature, pressure difference of each filter element, etc.) need to be manually read and recorded for archiving. Manual calculation of the air compressor specific power is time-consuming and labor-intensive, and it is not possible to conveniently test the air compressor at different locations, and the test data is not recorded online, which needs to be improved. In view of this, we propose a portable screw air compressor comprehensive test bench. Utility Model Content
