The height of the auxiliary pipe 4 is approximately the same as the height of the water-passing trough 1. The motor inside the pump body of the dual vertical centrifugal pump is connected to a frequency converter 5 and an industrial control board via an electrical circuit. A flow stabilizing valve 6 is connected to the input end of the pump body 3, and a pressure gauge 7 connected to the industrial control board is installed at the output end of the pump body.

[0025] In order to make the whole water tank easy to maintain, convenient for overhaul, the utility model provides technical scheme still includes: water tank 1 is combined by a plurality of rectangular water tank panel 8, the right side of water tank panel 8 is provided with a group of symmetrical L-shaped lugs 9, the left side is provided with T-shaped recess 10 of adapting L-shaped lug 9, the gap in the middle of T-shaped recess 10 extends out elastic limiting block 11, and the clearance between the L-shaped lug 9 combined with T-shaped recess is adapted with elastic limiting block 11, when the two are combined, the tight fit between elastic limiting block 11 and L-shaped lug, the bottom surface of rectangular panel is provided with connecting column 12, and the top surface of rectangular panel is provided with connecting groove 13 of adapting connecting column 12. The turning point of the edge of water tank 1 is combined through turning column 14, and the turning column 14 is a square column, and the two sides of the square column are provided with L-shaped lug 9, T-shaped recess 10 and elastic limiting block 11 respectively. The vertical joint of water tank panel 8 is installed with first silica gel waterproof pad 15, and the horizontal joint of water tank panel is installed with second silica gel waterproof pad 16, and the second silica gel waterproof pad 16 is provided with hole 17 of adapting connecting column 12. The side of first silica gel waterproof pad 15 and second silica gel waterproof pad 16 extends out water retaining surface 18, and the water retaining surface 18 partially covers the non-splicing surface of water tank panel 8. The middle part of water tank panel is inwardly raised to form spherical surface 19. The end of water inlet pipe 2 is connected to the inside of water tank 1 and drain valve 21 through three-way pipe 20.

[0026] The working principle of the utility model is as follows, water flow enters the device from the external water source through water inlet pipe 2 and is first pre-regulated through auxiliary pipe 4, the water flow in the water inlet pipe is kept stable, and air or impurities in the pipeline are also removed. The double vertical centrifugal pump is started, water is pumped out from the water source and the output pressure is monitored through pressure gauge 7. Frequency converter 5 adjusts the motor speed according to the instructions of the industrial control board to realize accurate control of the pumping flow and pressure. The steady flow valve 6 is used to stabilize the water flow into the pump body, so as to avoid the efficiency drop or equipment damage caused by flow fluctuation. Pressure gauge 7 monitors the pressure state of the system in real time, provides feedback information for the industrial control board, and adjusts the parameters of the built-in motor of the pump body 3 in time, so as to ensure the stable and normal operation of the system.

[0027] The water tank is combined by a plurality of rectangular water tank panels 8, so that the whole water tank can be flexibly assembled and disassembled, and transportation and installation are facilitated. One side of each water tank panel is provided with a group of symmetrical L-shaped lugs 9, and the other side is provided with T-shaped recess 10 adapted thereto.

After heating and drying the latex, the disassembly work can be completed more easily after cooling.

[0029] The middle part of the sink panel is inwardly raised to form a spherical surface 19. The spherical surface structure increases the structural strength of the panel, and can also disperse the impact of the water flow on the panel to some extent, improving the durability of the sink. Since the sink panel is designed to be spliced, during actual installation, only the panels need to be aligned according to the design requirements of the L-shaped protrusions 9 and the T-shaped grooves 10, and then the assembly can be completed through simple plug-in operation in the vertical direction. The disassembly process loosens or pulls out the connecting columns 12 and the connection relationship between the L-shaped protrusions and the T-shaped grooves in the opposite order, so that the panels can be easily separated, which is convenient for maintenance or replacement.
