Electrical "Nurse" for Pipeline Guards Pump
One glance at the control desk at pumping stations along a 1,700-mile pipeline
stretching from Texas to the East Coast shows the operator what valves are open
or closed. The electrical "nurse," built by Westinghouse, also takes the temperature
of motors, pumps and bearings and feels the "pulse," or pressure, in the pipe. The
top of the control desk is made of semi-transparent plastic with illuminated arrows
on the station diagram showing the route of the oil. If a pump gets hot or develops
abnormal temperature, a tiny red bulb flashes on to show the trouble spot on the
diagram. Automatic controls stop the electric motor operating the overheated pump,
close valves leading into the pump, cause other valves to open and re-route the
oil around the idle unit. Under the plastic desk top are some 60 pea-sized lamps,
green, amber or red, connected with valves, thermometers and pressure gages.
