Centrifugal compressor, inlet guide vanes, bearings

Do process gas centrifugal compressors have inlet vanes? How is flow rate generally adjusted? Is a tilting bearing a tile-type bearing? Does the bearing have a temperature alarm to shut it down? Or stop the machine due to oil temperature alarm?
Typical air compressors and vapor compression units are equipped with adjustable vane assemblies at the inlet to regulate the process flow rate. There are alarms and selective shutdown for bearing temperature. And the oil temperature usually only triggers an alarm.
1. Not necessarily； 2. Usually, the flow rate is adjusted by the opening degree of the inlet valve and the guide vanes. But the output factors also need to be considered. 3. Not necessarily ； 4. Most of them have it ； 5. Most systems have instrument control settings for oil temperature alarms and interlocks, but there are also systems that do not provide such settings for oil temperature. Note: Some interlocks are mandatory, while others can lead to accidental trips due to misoperation. For example, in actual use, bearing temperatures often cause the system to shut down due to a broken temperature sensor; therefore, some systems omit this feature. Everything should still be based on the instructions provided with the actual device, for reference only.
Do process gas centrifugal compressors have inlet vanes? How is flow rate generally adjusted? ---There are inlet guide vanes, which are installed in most units. Flow regulation is generally achieved through the inlet guide vanes, anti-surge circulation valves, and outlet line relief valves; some units are also equipped with variable frequency speed control to regulate flow by adjusting the speed. Is a tilting bearing a type of block bearing? ---Yes, does the bearing have a temperature alarm that triggers shutdown? Or stop the machine due to oil temperature alarm? ---It is generally equipped with
