These in turn open the water inlet valve or residue drain valve etc. Two hydraulic pumps help to open and close the supply of calcium carbide. This is fed into the generator by screw feed conveyors. The screw feed mechanism and the agitator are operated by flame-proof motors and fittings.
The entire operation is perfectly synchronised to give maximum efficiency and simplicity in operation. Any failure, whether it is of power supply, water, instruments air, is signalled visually and also audibly when an alarm bell rings to alert the operator.The design of the entire plant has been made with safety in mind. Flash Back Arrestors, High Pressure Reverse Flow check valves, safety valves and complete gauging help protect both equipment and personnel. Various auto controls, safety valves, auto vent valves, non-return valves and Flash Back Arrestors are also provided to make this plant absolutely safe to operate in all conditions.
