The utility model discloses a theory of operation does:
when the outdoor air temperature is low in winter, the main pump 6 is in an operating state, the backup pump 10 is in a standby state, and in order to prevent the water flow inside the backup pump 10 from freezing due to no flow, the backup pump inlet valve 9 and the backup pump outlet valve 12 are closed, and the return valve 14 and the anti-freeze valve 16 are opened, while keeping the two branch sewage valves 18, the inlet valve 21, the outlet valve 22 closed, and the through sewage valve 24 open.
At this moment, the main pump 6 works normally, the water flow output by the main pump 6 enters the inside of the outlet pipeline of the backup pump 10 from the outlet of the outlet pipeline of the backup pump 10 again under the action of pressure, enters the front end of the backup pump 10 through the return pipeline 13, enters the inside of the anti-freezing pipeline 15 after passing through the backup pump 10 and the backup pump check valve 11, and finally enters the inside of the loop of the main pump 6 through the anti-freezing pipeline 15, so that the water flow always passes through the backup pump 10 which does not work, the water flow at the front end and the rear end of the backup pump 10 cannot be frozen, and the backup pump 10 cannot work immediately. Meanwhile, the flowing water in the through pipeline 20 flows out through the through blowdown pipeline 23, so that the through pipeline 20 cannot be frozen.
When the standby pump 10 needs to work, the anti-freezing valve 16 and the backflow valve 14 are closed again, the standby pump inlet valve 9 and the standby pump outlet valve 12 are opened, and the standby pump 10 can directly start to work.
When the standby pump 10 does not need to work or be used in winter, the inlet valve 9, the outlet valve 12 of the standby pump, the anti-freezing valve 16 and the backflow valve 14 are all closed, and the inlet valve 21, the outlet valve 22 and the two straight-through sewage pipes 23 are opened, so that water can directly flow into the water outlet main pipe 2 from the water inlet main pipe 1 through the straight-through pipeline 20 on one side of the standby pump 10 due to the pressure difference between the water inlet main pipe 1 and the water outlet main pipe 2 at the front end and the rear end of the straight-through pipeline 20, and the flow of water media in the pipeline on one side of the standby pump 10 can be guaranteed, and the freezing condition is avoided. Because the water flow in the pipelines at the front end and the rear end of the standby pump 10 is completely discharged by the sewage branch pipe 17, the standby pump 10 can be prevented from freezing, and when the standby pump needs to be started, the standby pump can be directly started by introducing the water flow.
Through the improvement of the system, the problem that the standby pump 10 is easy to freeze in winter is solved.
