High temperature oil pump is a kind of fluid machinery which can transform the mechanical energy of the prime mover into the mechanical energy of the fluid being transported. Generally speaking. If the fluid is liquid, it is called a pump; The fluid it transmits is gas, which is called fan.
High temperature oil pump plays a very important role in electric power production. In coal-fired power plants, To the water of the boiler feed water pump, sent to the steam turbine condenser cooling water circulating pump, lining the condensate in the condenser in the thermal system of condensation water pump, lining everywhere oleophobic oil transfer pump, filling water supply pump to the thermal network system, adding fuel to the boiler exhaust powder machine, to the boiler air blower, exclude the induced draft fan of boiler flue gas is an important auxiliary equipment for power plants. In addition, there are raw water pumps, industrial water pumps and special pumps used to transport all kinds of lubricating oil, liquid medicine, the removal of boiler ash and slag. In a word, high temperature oil pump is widely used in thermal power plants and plays an extremely important role. Therefore, someone once said, "If the power plant is compared to a person, then the high temperature oil pump is equivalent to the human heart or aorta, and the draught fan is equivalent to the human respiratory system." Human heart plays the role of metabolism, promoting blood circulation to maintain human life, high temperature oil pump in thermal power plants. It plays an important role in supplementing nutrition (coal, gas, water, etc.), eliminating garbage (value, smoke, etc.), promoting the power plant working medium (gas, steam, water, coal, oil) channel unobstructed, ensuring the normal power supply of the whole power plant.
Schematic diagram of pressurized water reactor nuclear power plant system. Nuclear power plant is composed of nuclear island and conventional island, and its power production process is basically the same as that of thermal power plant, so the role of high-temperature oil pump and condensate oil pump in conventional island is similar to that of thermal power plant. The function of the reactor coolant pump in the nuclear island is to force the coolant circulation and transfer the heat generated by the nuclear reaction in the reactor core to the steam generator to produce steam that can drive the turbine to do work.
