Test of thrust bearing of a multiplier centrifugal compressor.

The article describes the design of the experimental stand and the measurement system necessary for taking and recording readings of instrumentation and automation equipment. The basis of the stand is a centrifugal compressor unit of the multiplier type. The analysis of the results of experimental studies of a thrust sliding bearing with fixed pads at nominal and transient modes of operation of a centrifugal compressor with a closed impeller is given. The pulsations of the oil pressure in the bearing layer and the temperature of the working surface were measured at different rotor speeds depending on the lubricant supply temperature.
