Cooling Water Pumps
The Cooling Water Pump for the wells was manufactured by Vickers Gill Pumps, UK, and installed in the basement of "B" Station Turbine Hall in 1936. Supplying 1.2 million gallons of river water per hour to cool No. 6 turbine’s condenser, it was powered by a 280 horsepower, 440-volt Metropolitan Vickers motor. A larger pump was later installed in 1955 to serve No. 7 turbine’s condenser.
Rotary Strainer
The cast iron rotary strainer serves as the second stage of the cooling water process after it has been pumped from the wells. It filters the river water to help protect the condensers from debris and marine life such as fish, prawns, and jellyfish.
These strainers are designed to remove solid particles from the water flow by continuously rotating a screen through the fluid. A cleaning mechanism (typically a brush or backwash system) dislodges the trapped debris, which is then directed into a sediment or collection chamber.
Willans & Robinson supplied a range of equipment when they were awarded a contract in June 1914. This included three 3,000 kW three-phase turbo alternators complete with exciters, unit transformers, pumps, three surface condenser plants, auxiliary pumping systems for bilge water (a mixture of water, oil, grease, and debris), and low-pressure service water, along with their associated motors.
Isolating Valve
Seven Cooling Water Isolating Valves were installed in 1936 in the pump bay. Manufactured by Glenfield Kennedy of Kilmarnock, UK, the 36-inch diameter valves controlled the condenser cooling systems for 'B' and 'C' Stations. They were operated remotely from the Cooling Water Pump Control Panel, which was located upstairs in 'A' Station E.
An older, smaller model of the earlier Cooling Water Isolating Valve operating mechanism still exists at the East Perth Power Station.
