The utility model discloses the use profile is as follows:
the utility model discloses an use including differential compensation process and automatic water process of trading, wherein:
first, difference compensation process
When the municipal water network is low in water supply, the full-frequency-conversion control cabinet controls a first water outlet valve 9 at the bottom end of the first water tank 4 to be opened, and meanwhile, the auxiliary frequency-conversion pump group 3 is opened, so that the water in the first water tank 4 is used for difference compensation of the water network; when the first flow sensor 10 detects that the flow of water in the first water outlet pipe 8 gradually decreases and approaches zero, a signal is transmitted to the full-variable-frequency control cabinet, the full-variable-frequency control cabinet controls the second water outlet valve 15 at the bottom end of the second water tank 5 to be opened, the water in the second water tank 5 is used for differential compensation of a water network, and meanwhile, the first water outlet valve 9 is controlled to be closed;
at this time:
1. when the water supply amount of the municipal water network is recovered to normal water supply, the variable frequency control cabinet controls the second water outlet valve 15 to be closed, then controls the first water inlet valve 7 and the second water inlet valve 13 to be opened, supplements water sources into the first water tank 4 and the second water tank 5 to set water levels (detected by the first water level sensor 11 and the second water level sensor 17 and fed back), and then closes the first water inlet valve 7 and the second water inlet valve 13;
2. when the second flow sensor 16 detects that the water flow in the second water outlet pipe 12 gradually decreases and the water supply amount of the municipal water network does not recover to normal water supply, the variable frequency control cabinet controls the auxiliary variable frequency pump set 3 to stop and controls the second water outlet valve 15 to close at the same time, and water sources are replenished into the first water tank 4 and the second water tank 5 again until the water supply amount of the municipal water network recovers to normal;
(it should be noted that how to obtain the water supply of the municipal water network is the conventional technical means, for example, a pressure sensor for detecting the water pressure of the pipeline is generally arranged on the pipeline where the pressure stabilizing and flow stabilizing mechanism is arranged, and the pressure sensor is connected with the variable frequency control cabinet by signals, and the person skilled in the art can set the pressure sensor according to the conventional technical means in the practical application process)
