How to detect faults in equipment which call for maintenance?

This technique employs the method of study approach to detect faults in equipment which call for maintenance. It aims at diagnosis of the trouble spots with a view of designing it out and thus reducing the volume of maintenance work.

Poor design of equipment leads to frequent breakdown. An appropriate choice of tribioIogical material might eliminate the need for subsequent breakdown frequency.

Principle of Design out maintenance is to design the equipment such that no minimum failures occur.

The design improvement can meet one of three objectives –

(a) Prevention of future defect.

(b) Early recognition of the fault.

(c) More difficult & more efficient repair.

The alternatives for implementation are –

(a) Modify the design.

(b) Modify the Operation.

(c) Modify the Maintenance schedule.
