As shown in fig. 1, an embodiment of the present invention provides an energy-saving non-negative pressure water supply apparatus 100, which includes a tap water pipe 1 and a user pipe 15; and a first connecting pipe 4, a pump unit and a water supply pipe 16 disposed between the tap water pipe 1 and the user pipe 15; the first connecting pipeline 4 is communicated with the tap water pipeline 1 and the pump set unit; the pump unit is arranged between the first connecting pipe 4 and the water supply pipe 16; the water supply pipe 16 communicates the pump unit and the user pipe 15; the pump set unit comprises a first water pump 5, a second water pump 6 and a third water pump 7, wherein the flow of the first water pump 5, the flow of the second water pump 6 and the flow of the third water pump 7 are increased in sequence; the first water pump 5, the second water pump 6, and the third water pump 7 are connected in parallel between the first connection pipe 4 and the water supply pipe 16.
In the energy-saving non-negative pressure water supply equipment 100, the pump set unit further comprises a fourth water pump 8 connected in parallel with the first water pump 5, the second water pump 6 and the third water pump 7 between the first connecting pipeline 4 and the water supply pipeline 16, and the flow rate of the fourth water pump 8 is the same as that of the third water pump 7. Wherein, fourth water pump 8 and third water pump 7 are each other for reserve, and in actual use, fourth water pump 8 and third water pump 7 alternative start.
For example, the flow rate of the first water pump 5 is 1/4 of the user water consumption of the user pipeline 15; the flow rate of the second water pump 6 is 1/3 of the water consumption of the user pipeline 15; the flow rates of the third water pump 7 and the fourth water pump 8 are 1/2 of the water consumption of the user pipeline 15 respectively, the flow rate design can maximize the efficiency of the water pumps, and the energy-saving effect is optimal. Of course, in other embodiments of the present invention, the flow rates of the first water pump to the fourth water pump may be set to other values.
The first water pump 5, the second water pump 6, the third water pump 7 and the fourth water pump 8 have the same lift.
In this embodiment, in the energy-saving non-negative pressure water supply apparatus 100, the pump unit includes a plurality of water pumps connected in parallel between the first connection pipeline 4 and the water supply pipeline 16, and the flow rate of each of the plurality of water pumps is sequentially increased.
As shown in fig. 1, a tap water pipe 1 is used for connecting a municipal water supply network, and the tap water pipe 1 feeds water from the municipal water supply network into a steady flow tank 3; a first water pump 5, a second water pump 6, a third water pump 7 and a fourth water pump 8 in the pump group unit respectively take water from the flow stabilizing tank 3 through a first connecting pipeline 4 and supply pressurized water to a water supply pipeline 16; and then supplied through the distributor 9 toward the user duct 15.
In a preferred embodiment, the water supply pipe 1 is provided with a first pressure transmitter 2 for detecting the water pressure in the water supply pipe 1 and transmitting the water pressure in the water supply pipe 1 to the control unit 17 in time.
In a preferred embodiment, a second connecting pipe 10 and a storage tank 11 are further provided on the distributor 9, and the second connecting pipe 10 connects the distributor 9 and the storage tank 11. Wherein, a second pressure transmitter 14 and an electric contact pressure gauge 13 are arranged on the user pipeline 15; a third pressure transmitter 12 is provided on the storage tank 11.
The second pressure transmitter 14 is used for detecting a first actual pressure of the water flow in the user pipeline 15 and feeding back the first actual pressure to the control unit 17; at the same time, the electro-contact pressure gauge 13 displays the first actual pressure. The control unit 17 controls at least one of the first water pump 5, the second water pump 6 and the third water pump 7 (or the fourth water pump 8) of the pump set unit to start according to the first actual pressure, so that the flow rate of each water pump in the pump set unit is matched with the water consumption of a user.
In addition, the control unit 17 can also supply water towards the user line 15, depending on the first actual pressure, also using the reservoir 11, the second connecting duct 10 and the distributor 9.
The third pressure transmitter 12 is adapted to detecting a second actual pressure of the amount of water in the storage tank 11 and feeding back the second actual pressure to the control unit 17. The control unit 17 controls whether the dispenser 9 and the second connecting pipe 10 continue to supply water to the reservoir, depending on the second actual pressure.
For example, the control process of the automatic energy optimization method of the energy-saving non-negative pressure water supply apparatus 100:
the second pressure transmitter 14 detects a first actual pressure of the water flow in the user pipeline 15, and feeds the first actual pressure back to the control unit 17, wherein if the first actual pressure is smaller, the water consumption of the user is small, and the first water pump 5 is started; if the first actual pressure is higher, it indicates that the water consumption of the user is high, and the third water pump 7 is started.
Because the real-time water consumption of the user is dynamically changed, when the first water pump 5 is started to supply water towards the water supply pipeline 16, the first actual pressure monitored by the second pressure transmitter 14 in real time changes, for example, increases, which indicates that the water consumption demand of the user increases, that is, the first water pump 5 cannot meet the water consumption demand of the user, at this time, the control unit 17 controls the second water pump 6 to be started first, and the first water pump 5 is slowly stopped. And if the first actual pressure is still low after the second water pump 6 is started, it indicates that the flow of the second water pump 6 cannot be adapted to the water consumption of the user, at this time, the third water pump 7 (or the fourth water pump 8) is started first, and the second water pump 6 is slowly stopped. If the first actual pressure is still low after the third water pump 7 (or the fourth water pump 8) is started, controlling the first water pump 5 to start, and at the moment, starting the third water pump 7 (or the fourth water pump 8) and the first water pump 5 simultaneously; if the first actual pressure is still lower, the second water pump 6 is controlled to be started first, then the first water pump 5 is slowly closed, and at the moment, the third water pump 7 (or the fourth water pump 8) and the second water pump 6 are started at the same time.
In addition, if the third water pump 7 (or the fourth water pump 8) and the second water pump 6 meet the requirement of the user on the ultra-large water consumption, the control unit 17 controls the fourth water pump 8 to be started firstly, and meanwhile, the second water pump 6 is slowly closed, and at the moment, the third water pump 7 and the fourth water pump 8 are started simultaneously. It should be noted that the duration of the simultaneous activation of the third water pump 7 and the fourth water pump 8 is not too long.
In this embodiment, the operating frequencies of the first water pump 5, the second water pump 6, the third water pump 7, and the fourth water pump 8 are all 50 Hz.
Since the real-time water consumption of the user is dynamically changed, when the first actual pressure monitored by the second pressure transmitter 14 in real time changes, for example, decreases, the start sequence of the water pumps of the pump set unit is opposite to the start sequence of the water pumps of the first actual pressure increase pump set unit.
Since the real-time water consumption of the user is dynamically changed, when the third water pump 7 and the second water pump 6 supply water to the water supply pipeline 16 at the same time, wherein the first actual pressure monitored by the second pressure transmitter 14 in real time changes, for example, decreases, the control unit 17 controls the first water pump 5 to start first, slowly closes the third water pump 6, and at this time, the third water pump 7 and the first water pump 5 start at the same time; if the first actual pressure is still lower, the control unit 17 continues to control the second water pump 6 to start first, slowly closes the third water pump 7, and at this time, the second water pump 6 and the first water pump 5 start at the same time; if the first actual pressure is still lower, the control unit 17 controls the third water pump 7 to start first, and simultaneously slowly closes the first water pump 5 and the second water pump 6, and at this time, the third water pump 7 is started independently; if the first actual pressure is still lower, the control unit 17 controls the second water pump 6 to start first, slowly closes the third water pump 7, and at the moment, the second water pump 6 is started independently; if the first actual pressure is still lower, the control unit 17 controls the first water pump 5 to start first, and slowly closes the second water pump 6, and at this time, the first water pump 5 is started alone.
It should be noted that the first actual pressure is always higher, and if the control unit 17 determines that the first actual pressure is greater than the first set pressure, the energy distributor 9 can store the water in the water supply pipeline 16 into the storage tank 12 through the second connection pipeline 10.
In addition, the third pressure transmitter 12 on the storage tank 12 is used for monitoring the second actual pressure of the water amount in the storage tank 12 in real time and feeding back the second actual pressure to the control unit 17, and the control unit 17 judges that the second actual pressure is greater than the second set pressure, and at this time, the control distributor 9 and the second connecting pipeline 10 stop supplying water into the storage tank 11 continuously.
Further, under the condition that only the first water pump 5 in the pump set unit works, if the first actual pressure of the water flow in the user pipeline 15 is still higher, the first water pump 5 is switched to variable-frequency constant-pressure control, and the operating frequency of the first water pump 5 is lower than 25 Hz; the control unit 17 judges that the water consumption of the current user is small, and the water consumption is small, at this time, the connection port of the second connection pipeline 10 is opened, the first water pump 5 is closed, and water is supplied to the user pipeline 15 through the storage tank 11 and the second connection pipeline 10 via the distributor 9. When the first actual pressure of the water flow in the user pipeline 15 is reduced and lower than the initial set pressure, the water pumps are sequentially started according to the starting sequence of the pump set units in the process of increasing the first actual pressure.
In summary, based on the energy-saving non-negative pressure water supply apparatus 100 of the present invention, the present invention also relates to an automatic energy optimization method of water supply, which includes:
acquiring a first actual pressure of water flow in a user pipeline, and feeding back the first actual pressure to the control unit 17; and

the control unit 17 controls one of the fourth water pump 8 and the third water pump 7 to be started according to the first actual pressure.
In a preferred embodiment, the energy-saving non-negative pressure water supply apparatus 100 further comprises a distributor 9 connected to the user pipe 15, a second connecting pipe 10 connected to the distributor 9, and a storage tank 11 connected to the second connecting pipe 10; wherein the content of the first and second substances,
if the first actual pressure is greater than the first set pressure, the dispenser 9 is controlled to supply water through the second connecting duct 10 towards the storage tank 11.
In a preferred embodiment, the automatic energy optimization method of the energy-saving non-negative pressure water supply apparatus 100 further comprises: acquiring a second actual pressure of the amount of water in the storage tank 11; if the second actual pressure is equal to the second set pressure, the supply of water to the storage tank 11 using the dispenser 9 and the second connecting pipe 10 is stopped.
In a preferred embodiment, the automatic energy optimization method of the energy-saving non-negative pressure water supply apparatus 100 further comprises:
the control unit 17 controls the first water pump 5 to start supplying water towards the user pipeline 15 according to the first actual pressure; if the first actual pressure is greater than the first set pressure, the first water pump 5 is controlled to be turned off and water is supplied toward the user pipe 15 through the storage tank 11, the second connection pipe, and the dispenser 9.
