The main water inlet pipe 110 of the pump station is connected with a water source, and the main water outlet pipe 120 is connected with a sedimentation tank or a filter tank.
The pump station has two modes for starting the pump set and filling water in the embodiment: the first method is that water is pumped by a water ring vacuum pump 5 and is accumulated in a water-gas separation tank 4, and then the accumulated water in the water-gas separation tank 4 is filled into a pump set through a first water filling pipeline 6; the second is to draw water from the pump group that is in operation and fill the other pump groups that are ready to be activated.
The embodiment is provided with 3 pump groups, namely a first pump group 1, a second pump group 2 and a third pump group 3, and the pump station can adjust the working states of the 3 pump groups according to the water consumption. When 3 pump sets all need to be started, the pump sets must be started by filling water in a first water filling mode. When at least 1 pump set is in working state, the first or second water filling mode can be selected to start the rest pump sets.
When the second water filling mode is adopted, at least 1 pump set works, so that water still flows out of the main water outlet pipe 120, and the water in the main water outlet pipe 120 is guided to the pump set to be started through the second water filling pipeline 7 to be filled with water and started.
The water-gas separation tank 4 is a container for storing water, an air outlet 41 is arranged at the upper part of the water-gas separation tank 4, a water inlet 42 is arranged at the bottom of the water-gas separation tank 4, and a water outlet 43 is arranged at the lower part of the water-gas separation tank 4.

When the water amount is accumulated enough to open the pump unit, the water ring vacuum pump 5 and the third electric switching valve 44 are turned off, and the fourth electric switching valve 45 provided at the water discharge port 43 is opened to fill the pump unit with water.
In this embodiment, the check valve 8 is disposed on the pipeline between each pump set and the main water inlet pipe 110, so as to prevent the water filling for starting the pump set from running off along the water inlet pipe.
This embodiment has 3 sets of check valves 8 installed, 1 set for each pump set.

Therefore, two electric switch valves are installed, the water filling branch pipe can be guaranteed to be closed, and the starting of other pump sets is prevented from being influenced. Meanwhile, a first manual switch valve 93 and a second manual switch valve 94 are arranged on the water filling branch pipe for the convenience of maintenance and replacement of the first electric switch valve 91 and the second electric switch valve 92. The first manual switching valve 93, the first electric switching valve 91, the second electric switching valve 92 and the second manual switching valve 94 are connected in series in sequence along the water flow direction of the water-filled branch pipe, and the first manual switching valve 93 and the second manual switching valve 94 can be replaced or maintained after the first manual switching valve 93 and the second manual switching valve 94 at both ends are closed.
In addition, in order to avoid the blocking of the water filling branch pipes caused by the failure of the first electric switch valve 91 or the second electric switch valve 92 to open, a bypass line 95 is connected to each water filling branch pipe in the present embodiment. One end of the bypass line 95 is connected to the water inlet end of the first manual switch valve 93, the other end of the bypass line 95 is connected to the water outlet end of the second manual switch valve 94, and a third manual switch valve 96 is disposed on the bypass line 95.

In order to realize automatic control, a small control box 210 is installed beside each pump set for controlling the operation of the pump set, collecting operation data, and controlling the states of the check valve 8, each electric switch valve and the flow valve. A set of small control boxes 210 are also installed near the water-gas separation tank 4 and the water-ring vacuum pump 5 for controlling water pumping, water storage and water filling to the pump group.
The main control room is further provided with a large control cabinet 220 for receiving the operation data collected by each small control box 210 and sending an operation instruction to each small control box 210.
In this embodiment, the water-gas separation tank 4 is provided with a negative pressure sensor 46. When the pressure at the top of the water-gas separation tank 4 is detected to be converted from positive pressure to negative pressure and reaches a set value, a vacuum signal is formed, the operation of the water-ring vacuum pump 5 can be stopped, the third electric switch valve 44 is closed, and then the pump set is started. The check valve 8, the first electric switch valve 91 and the second electric switch valve 92 are opened after a certain time delay after the pump set is started.
For pump groups with relatively short downtime, the pump groups can also be started directly without filling water.
In this embodiment, the first pump group 1, the second pump group 2, and the third pump group 3 are all variable frequency water pump units. The variable-frequency water pump unit has low energy consumption in partial load, and the control system can dynamically adjust the opening states and the pumping power of the first pump unit 1, the second pump unit 2 and the third pump unit 3 according to the real-time water quantity demand so as to achieve the purpose of reducing the energy consumption. In addition, the water outlet side of each pump set is provided with a pressure sensor 10, and the control system can adjust the output power of each running pump set according to the pressure value fed back by the pressure sensor 10 so as to keep the pressure balance of the water outlet side of each pump set.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
