Embodiment 1
[0042] figure 1 An automatic control device for desalinated water pumps in nuclear power plants is shown, which includes:
[0043] Three water tanks 1 are used to store water for nuclear power plants, and the liquid level of the water tanks is 10 to 15 meters;
[0044] The main pump 7 is connected to the water tank 1 for continuously supplying water to the nuclear power plant;
[0045] 2 auxiliary pumps 7' and 7", connected to the water tank 1;
[0046] The jellyfish pipe 8 is connected to the pump group composed of the main pump 7 and the auxiliary pump 7' and 7 ";
[0047] The pressure detection unit 6 is used to detect the pressure value of the jellyfish pipe 8 at the water outlet of the pump group, which generates a signal 3;
[0048] And the control unit 5, which is connected to the pressure detection unit 6, receives the signal 3, and is used to control the start and stop of the auxiliary pump 7' or 7".
[0049] Preferably, the water outlet of the water tank 1 is als...
