Referring to fig. 2, a third water pressure sensor 23 is installed on the water outlet pipe 8.
Referring to fig. 9, the pump station further includes a controller, the controller includes a main control module, the pump station further includes a first motor driving module connected to the main control module, a second motor driving module and a relay module, the first motor driving module is connected to the centrifugal pump 2 and used for driving the centrifugal pump 2, the second motor driving module is connected to the speed reduction motor 3 and used for driving the speed reduction motor 3, the relay module includes a plurality of relay units, each relay unit is connected to each electromagnetic valve one by one and used for controlling the action of the electromagnetic valve, and the first water pressure sensor 10, the second water pressure sensor 13 and the third water pressure sensor 23 are all connected to a sampling signal input end of the main control module.
In the initial state, the inner screen 426 on the drum 403 is located in the third chamber 422, and the pump station has the maximum filtration flow; and the first solenoid valve 11 is in a conducting state and the other solenoid valves are in a closing state.
The working principle of the pump station is as follows: after the pump station is connected with a working power supply, the controller and the sensor are electrified to start. After the pump station is started, the controller sends a control signal to the first motor driving module, the first motor driving module drives the centrifugal pump 2 to start to operate, at the moment, the centrifugal pump 2 pumps an external water pipe, water flows into the water inlet pipe 7 after passing through the centrifugal pump 2 and flows into the first chamber 420 through the first shunt pipe 9, the water flows into the third chamber 422 after flowing through the external filter screen 424, the water then enters the rotary drum 403 through the internal filter screen 426, and finally flows into the water outlet pipe 8 from an opening at the lower part of the rotary drum 403, and finally the water is discharged through the water outlet pipe 8. In the process, water is filtered by the outer filter screen 424 and the inner filter screen 426 in a double-stage mode, so that impurities in the water can be effectively filtered, a good purification effect is achieved, and the sewage is changed into clear water.
In the whole filtering process, the first water pressure sensor 10 collects the water pressure in the first shunt pipe 9 and feeds back a water inlet pressure signal to the main control module; meanwhile, the third water pressure sensor 23 collects the water pressure in the water outlet pipe 8 and feeds back a water outlet pressure signal to the main control module. During the filtering process, some impurities may be attached to the outer filter 424 and the inner filter 426, resulting in an increasing pressure difference between the inlet water pressure and the outlet water pressure. When the pressure difference reaches the preset value, the controller sends a control signal to the second motor driving module, the second motor driving module drives the reduction motor 3 to rotate clockwise (with reference to fig. 7) by a certain angle, the rotating drum 403 rotates synchronously by the same angle, at this time, a part of the area of the inner filter screen 426 on the rotating drum 403 is located in the third chamber 422, and the other area of the inner filter screen 426 enters the fourth chamber 423, then the controller controls the conduction of the fourth electromagnetic valve 18, at this time, part of the water in the rotating drum 403 enters the fourth chamber 423 through the inner filter screen 426 and enters the second chamber 421 through the outer filter screen 424. In the process, the inner filter screen 426 in the fourth chamber 423 and the outer filter screen 424 in the second chamber 421 are washed reversely to wash away the inner impurities, and finally, the sewage mixed with the impurities is discharged through the second sewage discharge pipe 17.
After a period of time, the controller controls the first electromagnetic valve 11 and the fourth electromagnetic valve 18 to be closed, and simultaneously controls the second electromagnetic valve 14 and the fourth electromagnetic valve 18 to be conducted, and the second water pressure sensor 13 starts to detect the water inlet pressure in the second shunt pipe 12 and feeds a water pressure signal back to the controller. At this time, the water in the water inlet pipe 7 flows into the second chamber 421 through the second shunt pipe 12, then flows into the fourth chamber 423 through the outer filter screen 424 in the second chamber 421, then flows into the rotary drum 403 through a partial area of the inner filter screen 426 in the fourth chamber 423, and finally is discharged from the water outlet pipe 8. In the process, part of the water in the rotating drum 403 flows into the third chamber 422 through a partial area of the inner filter screen 426 in the third chamber 422, and then flows into the first chamber 420 through the outer filter screen 424 in the first chamber 420, so that the part of the inner filter screen 426 in the second chamber 421 and the outer filter screen 424 in the first chamber 420 are backwashed, the internal impurities are washed away, and finally the sewage mixed with the impurities is discharged through the first sewage discharge pipe 15. This completes the backwashing of the entire inner filter net 426 and all outer filter nets 424, and allows the impurities accumulated in the backwashing filter device 4 to be discharged. In this step, the controller controls the decelerating motor 3 to synchronously drive the rotating drum 403 to slowly rotate anticlockwise, i.e. to slowly rotate while flushing, so as to ensure that the impurities are effectively flushed and enable the effective filtering flow to gradually meet the flow required by the current working condition.
When the inner filter screen 426 is completely inserted into the fourth chamber 423, the backwashing is finished. At this time, the controller controls the third electromagnetic valve 16 to close, and at this time, all the water in the drum 403 is discharged through the water outlet pipe 8.
For the next backwash, the drum 403 is rotated counterclockwise until the inner filter 426 enters the third chamber 422 completely, which will not be described in detail!
The pump station can simultaneously carry out backwashing work in the filtering process, can start the backwashing mode without closing the filtering mode, and has high filtering efficiency; and the back washing mode can be automatically started according to the pressure difference of water inlet and outlet of the pump station, so that the system is more intelligent.
