FUNCTION OF NOZZLE
A nozzle is a mechanical device designed to control :-
Direction of a fluid flow entering into chamber via very tiny spray holes.
The rate of flow.
Speed.
Direction and pressure of the stream emerging from them.
Role of nozzle in injector:
Better dispersion.
Control of air fuel ratio.
Enhancement of power output.
GRINDING PROCESS
Method of material removal.
High throughput.
Regulating & Grinding wheel.
Axial movement.
An angular adjustment of 0 to 8 or 10 degrees.
Center less grinding is classified into two types:
Through feed grinding
Plunge grinding
Need Of Upgradation
Why automate, why improve?
Automation is all about elimination of manufacturing errors originating from human error .
Automation frees up your human work force to do quality and management task, that only humans can do.
“More and better" is today's bottom line.
The foundation is PLCs and computers in your plant .
Additions and changes to the programs they use will be of minimum cost,related to the large return in profits, your company will see.
