A displacement probe is installed on the compressor; how should mechanical serial numbers be assigned?
Push the compressor rotor toward the main thrust bearing to make the adjustment
The rotor position is usually set by mechanical personnel, after which instrumentation personnel install the instrument probes. Total compression stroke of the compressor: After installing the positioning bearings, push the compressor to one end first, then to the other end. The size of the back-and-forth stringing is the total stringing size. After positioning the rotor in the center as required, the instrumentation staff then installs the displacement probe.
During maintenance, we usually just need to push the rotor to its two extreme positions, calculate the total play, then place the rotor at one of the extreme positions and inform the instrument.
