AUTOMATIC TEMPERATURE CONTROL IN VACUUM BRAZING FURNACE USING P.L.C

ABSTRACT
The main objective of this project is to maintain & control temperature uniformly of the two zones in vacuum brazing furnace and braze similar or dissimilar components using certain chemicals, for the given specifications of a job
Brazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel ..............etc

Vaccum Brake System
The vacuum brake is a braking system employed on trains and introduced
in the mid-1860s. A variant, the automatic vacuum brake system, became
almost universal in British train equipment and in those countries influenced
by British practice. Vacuum brakes also enjoyed a brief period of adoption
in the USA, primarily on narrow gauge railroads. However, its limitations
caused it to be progressively superseded by compressed air systems starting
in the United Kingdom from the 1970s onward. The vacuum brake system is..............etc

INTRODUCTION
Steam ejectors are designed to convert the pressure energy of a motivating fluid to velocity energy to entrain suction fluid and then to recompress the mixed fluids by converting velocity energy back into pressure energy. This is based on the theory that a properly designed nozzle followed by a properly designed throat or venturi will economically make use of high pressure fluid to compress from a low pressure region to a higher pressure. This change from pressure head to velocity head is the basis of th..............etc
