FAULT DIAGNOSIS OF PUMP-MOTORSET BY USING CONDITION MONITORING AND IOT TECHNIQUE

Condition monitoring is a methodology for observing a parameter related to the health of a machine or system .It pertains to hardware, subsystem or a functional aspect of the machine. The goal is to distinguish or filter out a responsible component or portion that is leading to performance deficiency .It is by comparing the base line signature ( vibration, temperature, lubricant state etc.,) with the signature in the suspected or chosen signature at any other condition not matching with base line. This work deals with a motor-pump set. Faults like rotor unbalance, misalignment between the motor shaft and pump shaft despite the flexible couplings can lead to extra energy consumption, wear and tear of components all ultimately leading to failure of running of the set. A fractional horse power pump run by a motor is taken up. The signature of these accelerations using MEMS shall be transmitted using IOT mother board of Aurdino. After receiving the wifi signal in time domain on the computer a frequency domain plot will be obtained by using FFT program. Typical faults like the unbalance and misalignment are taken up for demonstrating the machinery fault diagnostic (MFD) technique used in Condition Monitoring (CM).
