Brief Description of the Drawings:

[0010] Figure 1 It is a schematic structural diagram of the present utility model. Specific Embodiments:

[0011] Referring to Figure 1 , the present utility model specifically adopts the following embodiments: It includes a water inlet pipeline 1, a water supply pump (7), a steady flow regulator 3, a pressure tank 11, and a variable frequency water supply control cabinet 18. The water inlet pipeline 1 is connected to the steady flow regulator 3. The bottom of the steady flow regulator 3 is connected to one end of a water delivery pipeline 19 through a transition pipeline 5. A water supply pump 7, a flexible joint 8, a check valve 9, and a butterfly valve 10 are sequentially installed on the water delivery pipeline 19. The other end of the water delivery pipeline 19 is connected to a water outlet pipeline 13. One end of the water outlet pipeline 13 is connected to the pressure tank 11. A remote pressure gauge 14 and a water outlet butterfly valve 15 are sequentially installed on the water outlet pipeline 13. Several water supply faucets 16 are provided at the other end of the water outlet pipeline 13; the variable frequency water supply control cabinet 18 is respectively connected to the remote pressure gauge 14, the water outlet butterfly valve 15, the check valve 9, the butterfly valve 10, and the water supply pump 7 through wires. A Y-type filter 2 is provided on the water inlet pipeline 1. A negative pressure suppressor 17 and a remote pressure gauge 14 are provided at the top of the steady flow regulator 3. A drain valve 4 is provided at the bottom of the steady flow regulator 3. The drain valve 4, the negative pressure suppressor 17, and the remote pressure gauge 14 are respectively connected to the variable frequency water supply control cabinet 18 through wires. The number of the water delivery pipelines 19 is at least two. A water supply pump 7, a flexible joint 8, a check valve 9, and a butterfly valve 10 are sequentially installed on each of the water delivery pipelines 19. The water delivery pipelines 19 are horizontally arranged with intervals in the middle. A small-flow water supply pipeline 6 is provided between every two adjacent water delivery pipelines 19. Both ends of the small-flow water supply pipeline 6 are respectively connected to the transition pipeline 5 and the water outlet pipeline 13. An electromagnetic valve 12 is installed on the small-flow water supply pipeline 6. The electromagnetic valve 12 is connected to the variable frequency water supply control cabinet 18 through a wire. The water supply pumps 7 on the water delivery pipelines 19 have the same or different powers.

[0012] When this new energy-saving equipment for slag flushing water supply pumps is in use, tap water enters the flow stabilizer 3 through the water inlet pipe 1 for flow stabilization to prevent excessive impact force. Then, it enters the water delivery pipe 19 through the transition pipe 5. A water supply pump 7 is installed on the water delivery pipe 19. There are several water delivery pipes 19, and a water supply pump 7 is installed on each water delivery pipe 19. The two ends of each water delivery pipe 19 are respectively connected to the transition pipe 5 and the water outlet pipe 13. By controlling the operation of the water supply pump 7 through the variable-frequency water supply control cabinet 18, only by controlling the opening and closing of the check valve 9 and the butterfly valve 10 by the variable-frequency water supply control cabinet 18 can the water supply function of the water supply pump 7 be realized. According to actual usage needs, the water supply pumps 7 can be installed with the same power or different powers. Then, according to actual usage needs, the corresponding water supply pumps 7, check valves 9, and butterfly valves 10 are controlled by the variable-frequency water supply control cabinet 18 to work. Finally, the water is sent to the slag flushing tank through the water supply faucet 16.

[0013] When the water supply volume is small, the water supply pump 7 is closed, the pressure tank 11 is started, the solenoid valve 12 is opened, and water is supplied through the small-flow water supply pipe 6. The pressure tank 11 provides pressure to the small-flow water supply pipe 6 to ensure smooth water supply. When the pressure tank 11 is started, the internal pressure of the water outlet pipe 13 is observed through the remote pressure gauge 14 to ensure that there is no pipe burst.

[0014] When normal water supply is carried out, the outlet butterfly valve 15 is in the open state.

[0015] A Y-type filter 2 is installed on the water inlet pipe 1, which can filter impurities in the tap water to prevent excessive impurities from blocking subsequent equipment and pipes.

[0016] The flow stabilizer 3 is equipped with a negative pressure suppressor 17, which can relieve pressure inside it to prevent excessive pressure and explosion. According to the remote pressure gauge 14 on the flow stabilizer 3, the pressure inside the flow stabilizer 3 is observed, and then pressure relief is carried out through the negative pressure suppressor 17. These operations are all controlled by the variable-frequency water supply control cabinet 18. A drain valve 4 is also provided at the bottom of the flow stabilizer 3 for discharging impurities and garbage.

[0017] In summary, this new energy-saving equipment for slag flushing water supply pumps uses water supply pumps and small-flow water supply pipes to supply water according to actual situations, playing an energy-saving role, saving both electric energy and water energy; according to actual usage situations, the powers of the water supply pumps can also be different, thus playing a saving role.
