What is the function of open circulating water pump and shutdown in thermal power plant?
According to the water quality difference, the purpose is to provide the corresponding cooling water, for the system oil cooler, machine seal and other cooling. Open water directly from the circulating water pipe to use, the pump is delivered to the host, the small machine oil cooler, water quality is not very high, the circulating water drainage to the back pipe, water through the water filter filter impurities. The closed water takes the self closing water tank, which is used for removing salt water. General supply pumps, water pumps, sealing cooling water, condensate pumps, sealing water, generator, hydrogen cooler and other requirements of good water quality system, closed water self circulation, and through the cooler and open water circulating water heat exchange.Thermal power plant is referred to as the thermal power plant, is the use of coal, oil and natural gas as a fuel production power plant, it is the basic production process: fuel combustion in the boiler heating water into steam, fuel chemical energy into heat energy, steam pressure and steam turbine rotation, converts heat energy into mechanical energy and steam turbine rotate the generator, the mechanical energy into electrical energy.
The problem is unclear and it is not clear what the question is. Is the pump open or closed or is the valve closed? Or else?

Open pump and closed pump, circulating water pump seems to be the full name of the pump, the industrial pump is to provide industrial water. Both open and closed pumps provide cooling water on the side of the machine, just because the requirements for water quality are different. Closed water is desalted water, while open water is recycled water.
