Introduction:
Rotor spinning is also
called as break spinning. In any industry the performance of the machine plays
an important role in order to determine the productivity. Productivity is
effective utilization of man, power and machine. Hence in order to keep machine
in good condition there is a need of good maintenance activity. Hence the
maintenance activity of rotor spinning is explained in the following article.
Components of total productive maintenance:-
Preventive
Maintenance:
Preventive maintenance is performed regularly on equipment so that their should
not be any sudden break down. It is performed while the equipment is still
working so that it does not break down unexpectedly.
Corrective
Maintenance:-
Corrective maintenance is a maintenance task performed to identify, isolate,
and rectify a fault so that the failed equipment, machine, or system can be
restored to an operational condition within the tolerances or limits
established for in-service operations.
Predictive Maintenance: It is the technique to predict the future failure points of a machine component. So that the component can be replaced, based on the plan just before it fails.
Lubricants:-
There are 2
types of lubricants on the basis of viscosity:
Oil
Grease
Importance of Lubricants:-
Reduction
of wear & tear reduces machine maintenance time & cost
Legibility
assurance of m/c & m/c parts.
Higher
operating efficiency less idel time & stopping.
Reduces
fatigue & boredom of work forces due to well running less stoppage & troubles.
Develop
ergonomic & improve working environment.
