In order to overcome the defect, when the lift of the water pump is selected, a pressure-superposed water supply mode is used as a reference, and when the water pump is converted into a cut-off water tank for supplying water, an auxiliary water pump with lower lift and large flow is added in front of a water supply unit of the water pump to simulate the pressure of tap water. And a water supply mode switching electric valve is added.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a dual mode water supply system; the water supply system mainly comprises a cut-off water tank 1, two sets of water supply units, and a control cabinet for controlling the operation states of the cut-off water tank and the two sets of water supply units; it is characterized in that; after entering a home, a municipal tap water pipeline is sequentially connected with a pressure transmitter 3, a control valve 4, a Y-shaped filter 5 and a remote water meter 6 through pipelines, wherein a branch pipeline behind the remote water meter is divided into two branches, one branch is connected with a cutoff water tank, the other branch is connected with a pressure-superposed water supply unit 2-1 through a pressure-superposed master control valve 2-3, and a water outlet of the pressure-superposed water supply unit is connected with a water outlet main pipe 7; the water outlet control valve of the cut-off water tank is connected with the water tank water supply unit 2-2, and the water outlet of the water tank water supply unit is connected with a water outlet main pipe;
the pressure-superposed water supply unit 2-1 comprises two pressure-superposed water supply branches which are connected in parallel and have the same structure and are branched by a pressure-superposed water distribution main pipe 2-10, wherein a pressure-superposed water inlet control valve 2-11, a pressure-superposed hose joint 2-12, a pressure-superposed water pump 2-13, a pressure-superposed check valve 2-14 and a pressure-superposed water control valve 2-15 are sequentially connected to the pressure-superposed water supply branches from a water inlet end, and a water outlet of the pressure-superposed water control valve is connected with a water outlet main pipe 7;
the water tank water supply unit 2-2 comprises two water tank water supply branches which are connected in parallel and have the same structure and are branched by a water tank water distribution main pipe 2-20; the water supply branch of the water tank is sequentially connected with a water inlet control valve 2-21 of the water tank, a hose joint 2-22 of the water tank, a water pump 2-23 of the water tank, a check valve 2-24 of the water tank and a water outlet control valve 2-25 of the water tank from a water inlet end; and the water outlet of the water tank water outlet control valve is connected with a water outlet main pipe 7.
According to the preferable technical scheme, the water outlet main pipe is further connected with a pressure stabilizing branch 9, a pressure stabilizing control valve 10 is installed on the pressure stabilizing branch, and a water outlet of the pressure stabilizing control valve is connected with a pressure stabilizing tank 11.
Preferably, the water inlet of the cutoff water tank is provided with a remote control ball cock 12.
Preferably, the water inlet end of the pressure-superposed water supply unit is also provided with a backflow preventer 13.
The signal branch of the control cabinet is input by the water inlet pressure transmitter 3 and converted to the water outlet pressure transmitter 8 through the remote water meter 6; the switch board is judged according to the data that water inlet pressure transmitter 3 obtained, and when municipal pipe network pressure satisfied pressure-superposed condition, acquiescence was opened and is folded the pressure-superposed state. And then when the water cannot meet the requirements of users and the pressure value meets the pressure-superposed condition, the control cabinet transfers the water tank water supply unit 2-2 as an assistant. And then, when the water consumption peak is reached, the pressure-superposed machine set 2-1 is closed and the water supply machine set 2-2 is started according to the data judgment of the pressure transmitter 3, and if the state can not meet the requirement, the control cabinet opens the pressure-superposed machine set 2-1 again as the assistance.
The working principle is that under the condition that a tap water pipe network meets the use condition, a pressure-superposed water supply mode is mainly adopted, and when two water pumps for pressure-superposed water supply cannot meet the requirements of users, a water tank unit is started to serve as auxiliary water supply. When the service condition of the tap water pipe network can not be met in the water consumption peak period, the tap water pipe network is converted into a cut-off water tank water supply mode, when two water pumps for supplying water to the water tank can not meet the requirements of users, the pressure-superposed machine set is started to serve as auxiliary water supply, the water supply amount of the pressure-superposed water supply machine set is small at the moment, and the influence on the tap water pipe network can not be generated.
In addition to the above water supply principle, even if the tap water network satisfies the use condition all day long, and the water supply mode of the cut-off water tank is not started or the start time is too short, the forced water supply mode of the cut-off water tank for two or three hours set by the automatic wake-up control system replaces the water in the cut-off water tank, thereby preventing the water quality of the cut-off water tank from being deteriorated due to long-term stagnation.
By adopting the technical scheme, the water supply mode of the cutoff water tank and the pipe network pressure-superposed water supply mode respectively use two sets of units, the water distribution main pipes of the two sets of units are respectively connected with the cutoff water tank and the tap water pipe network, and the water pump lifts can be selected according to respective working modes due to the adoption of the mode of separately using the water distribution main pipes, so that the curve of the water pump H, Q is more practical and more efficient. Taking an original dual-purpose one-standby 3 pump system as an example, although the number of two sets of units of the novel dual-mode water supply equipment is 4, the number of water pumps is increased, the response speed of the system is improved due to the fact that low-lift auxiliary water pumps and switching electric valves are omitted, and the total number of the water pumps is still 4; the pressure of users of the two sets of units is the same, so the water outlet main pipe adopts a common mode.
The system has the advantages that the system can fully utilize the mode that the number of the main water pumps is large, and the two-purpose one-standby mode is converted into the three-purpose one-standby mode, and the system has the advantages that: when equipment is selected, the flow of each water pump is 1/3 of the total flow, the flow of each water pump is reduced by 1/3 compared with a dual-purpose one-standby mode, and a water pump with smaller flow can be selected, so that the energy conservation is facilitated. (for example: if the total flow of the system is 30 cubic meters per hour, the flow of each water pump is 15 cubic meters per hour in a two-use one-standby mode, and if the total flow of the system is 10 cubic meters per hour in a three-use one-standby mode.)
Because a low-pressure auxiliary water pump, a mode switching electric valve and a pressure-superposed water tank are eliminated, the total volume of the equipment is reduced, and the energy consumption and the initial investment are further reduced.
For users, under the condition that the capacity of a tap water pipe network is not good enough, a cut-off water tank water supply mode can be applied; under the condition that a tap water pipe network can support user requirements, the purpose of energy conservation and emission reduction is achieved mainly by a pressure-superposed water supply mode.
In the simple combination method, the water pump unit can only select one working mode from a cut-off water tank water supply mode or a pressure-superposed water supply mode. The novel dual-mode water supply equipment can work in a certain mode, and meanwhile, another mode is started to serve as an auxiliary means to supply water, so that the novel dual-mode water supply equipment is more flexible to use, and the system redundancy is better.
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.
