4020 – 07 – Different Predictive Maintenance Techniques

1m

Maintenance professionals need to use a wide variety of techniques and instruments when using predictive maintenance. At the start of a PDM program, a maintenance technician takes a baseline reading of the machine. They are taken when a machine is operating normally, so difficulties can be known early. PdM technicians get readings about machine vibration, temperature and many other factors that get recorded for later use. After these readings, PDM technicians will check the machines from time to time.

One of the most performed PdM tests is vibration analysis. Instruments are used to monitor and test the machine vibration to make sure it is functioning properly. Any change in vibration can change the housing for the rotating parts of the machine. They should be able to detect any change in vibration and discover any issue in the machine.
