[0017] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] like Figure 1 As shown, the liquid supply system in this embodiment includes a liquid storage tank 1, a liquid delivery component 2, and a pressurized energy storage component 3. The liquid storage tank 1 is used to store liquid. The inlet of the liquid delivery component 2 is connected to the outlet of the liquid storage tank 1. The pressurized energy storage component 3 includes an energy storage tank 31 and a high-pressure gas supply component 32. The inlet of the energy storage tank 31 is connected to the outlet of the liquid delivery component 2. The outlet of the high-pressure gas supply component 32 is connected to the inlet of the energy storage tank 31. The inlet of the energy storage tank 31 is located above the liquid level in the energy storage tank 31. The high-pressure gas supply component 32 is used to deliver gas into the energy storage tank 31 to discharge the liquid in the energy storage tank 31 through gas pressure. The outlet of the energy storage tank 31 is connected to the liquid replenishment terminal 15.

[0019] Specifically, the liquid in the storage tank 1 is stored according to the liquid required by the replenishment terminal 15. For example, if the replenishment terminal 15 requires water, a certain amount of water can be pre-stored in the storage tank 1. Of course, when the replenishment terminal 15 requires other liquids, other liquids can also be injected into the storage tank 1; there are no restrictions on this. Figure 1 As shown, a first drain pipe is installed on the liquid storage tank 1, and an eleventh valve 4 is installed on the first drain pipe to control the opening and closing of the first drain pipe. When the liquid storage tank 1 needs to store liquid, the eleventh valve 4 is closed. When the system stops working and the liquid in the liquid storage tank 1 needs to be drained, the liquid in the liquid storage tank 1 can be drained through the eleventh valve 4. For example, the eleventh valve 4 can be a manual valve, and its opening and closing can be manually controlled.

[0020] like Figure 1As shown, the liquid tank 1 is also provided with a second liquid level meter 5. The liquid level information in the liquid tank 1 can be obtained through the second liquid level meter 5, so as to control whether the liquid delivery assembly 2 continues to deliver liquid into the energy storage tank 31 according to the liquid level information in the liquid tank 1 obtained through the second liquid level meter 5. Specifically, when the liquid level in the liquid tank 1 is lower than a preset liquid level, the liquid delivery assembly 2 is controlled to stop delivering liquid, so as to reduce damage to the system caused by empty running.

[0021] When the liquid supply system in the embodiment works, a certain amount of gas is delivered into the energy storage tank 31 through the high-pressure gas supply component 32, and the liquid in the liquid tank 1 is delivered into the energy storage tank 31 through the liquid delivery assembly 2. Since the gas in the energy storage tank 31 is compressed when the liquid is delivered into the energy storage tank 31, the gas pressure in the energy storage tank 31 is increased, so that the liquid in the energy storage tank 31 can be discharged from the liquid outlet of the energy storage tank 31 under the action of the gas pressure, and then the liquid can be supplied through the liquid supplement terminal 15 of the energy storage tank 31. By using compressed air as power, continuous and timely water supply to the liquid supplement terminal 15 can be realized, the liquid delivery assembly 2 does not need to have instantaneous large-flow delivery capacity, and energy consumption can be reduced.

[0022] In the embodiment, as shown in Figure 1 The liquid supply system further includes a twelfth valve 6. The inlet of the twelfth valve 6 is connected with the liquid outlet of the liquid tank 1, and the liquid outlet of the twelfth valve 6 is connected with the liquid inlet of the liquid delivery assembly 2. The twelfth valve 6 is a manual valve, so that the liquid tank 1 and the subsequent liquid delivery assembly 2 can be reliably cut off in an emergency.

[0023] In the embodiment, as shown in Figure 1 The liquid delivery assembly 2 includes a first delivery pump 21. The inlet of the first delivery pump 21 is connected with the liquid tank 1, and the outlet of the first delivery pump 21 is connected with the pressurized energy storage assembly 3.

[0024] For example, the first delivery pump 21 can be a variable frequency pump. The variable frequency pump can accurately control the flow and pressure, is more energy-efficient, and gradually accelerates from low frequency and low speed to the required speed when starting, so as to reduce the impact of starting current on the power grid and the wear of mechanical components, and prolong the service life of the equipment.

[0025] In the embodiment, the liquid is delivered into the energy storage tank 31 through the first delivery pump 21. The specific model of the first delivery pump 21 can be selected as required. The lift of the first delivery pump 21 can only ensure that the liquid can enter the energy storage tank 31, and is not limited herein.

[0026] In the embodiment, as shown in Figure 1As shown, the infusion assembly 2 further comprises a first valve 22, a second valve 23 and a second delivery pump 24 arranged along the delivery path in sequence, the liquid inlet of the first valve 22 is connected with the liquid outlet of the liquid storage tank 1; the liquid inlet of the second valve 23 is connected with the liquid inlet of the first valve 22, and the liquid outlet of the second delivery pump 24 is connected with the liquid outlet of the first delivery pump 21.

[0027] The model of the second delivery pump 24 can be the same as that of the first delivery pump 21, which can be selected by those skilled in the art as needed, and is not limited herein.

[0028] The infusion assembly 2 in the embodiment comprises two groups of parallel delivery pumps, i.e. the first delivery pump 21 and the second delivery pump 24. When the first valve 22 and the second valve 23 are both in the open state, the first delivery pump 21 and the second delivery pump 24 can operate simultaneously to provide higher total flow to the system. When one of the first valve 22 and the second valve 23 is open and the other is closed, one of the first delivery pump 21 and the second delivery pump 24 operates independently and the other is closed, which can provide a certain flow. When one of them fails, the other can work normally, thereby improving the stability and working efficiency of the system. The working mode of the infusion assembly 2 can be selected as needed, and is not limited herein.

[0029] In the embodiment, as shown in Figure 1 The infusion assembly 2 further comprises a third valve 25, the liquid inlet of the third valve 25 is connected with the liquid outlet of the first delivery pump 21, and the liquid outlet of the third valve 25 is connected with the liquid inlet of the pressurized energy storage assembly 3.

[0030] For example, the third valve 25 can be a manual valve.

[0031] By setting the third valve 25 to control the opening and closing of the pipeline, it can be controlled whether the liquid delivered by the first delivery pump 21 enters the pressurized energy storage assembly 3. When an abnormal situation occurs or the downstream needs to be controlled, the first delivery pump 21 and the pressurized energy storage assembly 3 can be quickly isolated through the third valve 25, which is beneficial to improve the safety and reliability of the system.

[0032] As shown in Figure 1 The infusion assembly 2 further comprises a fourth valve 26, the liquid inlet of the fourth valve 26 is connected with the liquid outlet of the second delivery pump 24, and the liquid outlet of the fourth valve 26 is connected with the liquid inlet of the pressurized energy storage assembly 3.

[0033] The fourth valve 26 can control whether the liquid delivered by the second delivery pump 24 enters the subsequent pressurized energy storage assembly 3. The fourth valve 26 has the same effect as the third valve 25, and will not be described herein.

[0034] In the embodiment, as shown in Figure 1As shown, the liquid supply system further comprises a first pressure gauge 7, which is arranged on the pipeline between the liquid outlet of the liquid supply assembly 2 and the pressurized energy storage assembly 3.

[0035] It can be understood that by arranging the first pressure gauge 7 to obtain the pressure on the pipeline between the liquid outlet of the liquid supply assembly 2 and the pressurized energy storage assembly 3, whether the liquid supply assembly 2 is working normally can be determined according to the pressure information monitored by the first pressure gauge 7, so that timely adjustment can be made.

[0036] In the embodiment, as shown in the figure, Figure 1 The high-pressure gas supply component 32 comprises a gas supply member 321, a fifth valve 322 and a sixth valve 323 connected in sequence along the conveying path. The fifth valve 322 is a check valve, and the sixth valve 323 is a flow regulating valve. The outlet of the sixth valve 323 is connected to the gas inlet of the energy storage tank 31.

[0037] For example, the gas supply member 321 can be a compressor, which is arranged to provide high-pressure gas into the energy storage tank 31. Of course, the gas supply member 321 can also adopt other forms, which are not limited herein.

[0038] It can be understood that by arranging the gas supply member 321 to provide high-pressure gas into the energy storage tank 31, the fifth valve 322 can prevent the backflow of the gas into the energy storage tank 31, effectively ensuring the amount of gas in the energy storage tank 31, and the sixth valve 323 is a flow regulating valve, which can regulate the amount of gas entering the energy storage tank 31 according to the demand.

[0039] In the embodiment, as shown in the figure, Figure 1 The liquid supply system further comprises a second pressure gauge 8 arranged on the energy storage tank 31. The second pressure gauge 8 is used to obtain the pressure information in the energy storage tank 31, so as to adjust the opening degree of the sixth valve 323 according to the pressure information.

[0040] It can be understood that by arranging the second pressure gauge 8 on the energy storage tank 31 to obtain the pressure information in the energy storage tank 31 in time, the opening degree of the sixth valve can be adjusted in time according to the obtained pressure information, so as to supplement the gas into the energy storage tank 31 in time when the pressure in the energy storage tank 31 is lower than the set value, thereby accurately controlling the pressure in the energy storage tank 31, and enabling the energy storage tank 31 to stably and continuously supply water to the liquid supplement terminal 15.

[0041] In the embodiment, the liquid supply system further comprises a controller (not shown in the figure). The second pressure gauge 8 and the sixth valve 323 are electrically connected to the controller. The controller can adjust the opening degree of the sixth valve 323 according to the pressure information in the energy storage tank 31 obtained by the second pressure gauge 8. The connection mode and working principle of the second pressure gauge 8, the sixth valve 323 and the controller are conventional prior art, which will not be described in detail herein.

[0043] Specifically, the eighth valve 35 and the first liquid level meter 33 are electrically connected with the controller, so that the controller can control the opening degree of the eighth valve 35 according to the liquid level information acquired by the first liquid level meter 33. The connection mode and working principle of the first liquid level meter 33, the eighth valve 35 and the controller are conventional prior art, which will not be described in detail here.

[0044] It can be understood that by arranging the seventh valve 34, the backflow of the liquid into the energy storage tank 31 can be prevented, and the conveying assembly can be prevented from being damaged. According to the liquid level information in the energy storage tank 31 acquired by the first liquid level meter 33, the opening degree of the eighth valve 35 can be adjusted in time, so as to adjust the flow of the liquid into the energy storage tank 31, and the liquid supply amount in the energy storage tank 31 can meet the demand of the liquid supplement terminal 15, which is beneficial to the stable operation of the system.

[0049] It should be noted that by setting the flow meter 11, the flow information of the liquid outlet of the energy storage tank 31 can be obtained, so that the liquid flow output by the energy storage tank 31 can be adjusted according to the demand of the liquid supplement terminal 15.
