Seeking solutions to compressor commissioning issues?

Why is it necessary to pay attention to power overload and high exhaust temperature during air testing? I’m confused here; I hope an expert can help resolve my doubts.
If the molecular weight of the air is higher than that of the normal medium, it can lead to power overload; high exhaust temperatures may be due to a high compression ratio!
It is recommended to start by learning the principles of the equipment; it’s best not to delve too deeply into some irregular terms that are more like slogans. For example, in the case of \"power overload,\" what’s most straightforward to consider is that the rated current (the current indicated on the device’s ammeter, as specified on the label) must not be exceeded. In some areas, voltage levels have the greatest impact on power, and this effect is most evident in terms of current. It should indicate the methods and principles for controlling and adjusting operations to remain within the allowable parameter range. The exhaust temperature is too high; overload is not necessarily the cause of high exhaust temperature – it is necessary to identify the specific reason behind the elevated temperature. . . . . A casual question in the style of a slogan; this seems to be the origin of such phrases, and it’s best to ignore them. With all due respect, for your reference.
Attention should be paid when the testing medium and the process medium are different. Purpose: To protect the equipment.
It is mainly related to the medium used in compressor design; if the molecular weight of the design medium is greater than that of air, overload will not occur.
The design institute advises that for centrifugal compressors, when the volume is the same and the inlet and outlet pressures are the same, the compressor power has no relation to the molecular weight. For a given compressor, when different gases are used, the amount of gas drawn in remains constant; however, the compression ratio for higher molecular weight gases is greater than that for lower molecular weight gases. And power is directly proportional to the pressure ratio. The outlet temperature is directly proportional to the pressure ratio.
