The control box 11 has two sealed doors 12 inside, with sealing strips on the edges for good dust and water resistance. The right sealed door 12 has a handle 14 fixedly connected to its exterior. The handle 14 is made of non-slip material, making it comfortable to hold and easy to open and close. Both sealed doors 12 have grooves on their upper sides and are fixedly connected to acrylic plates 13. The acrylic plates 13 have high transparency, allowing for a direct view of the internal condition. The water pump assembly 2 includes a water pump box 21, which is a thickened metal shell with a stable and impact-resistant structure. The front of the water pump box 21 is fixedly connected to the rear of the connecting pipe 7, and the connection is reinforced with a sealing gasket to prevent water leakage.

The sealing flange a42 on the outside of the inlet pipe 41 ensures a sealed connection. The switch valve 43 can control the water flow rate. After the water enters the water pump box 21 of the water pump assembly 2, several water pumps 22 inside start working to initially pressurize the water.

The sealing flange b52 on the outside of the water supply pipe 51 ensures a sealed connection.

[0016] When water hammer occurs during water transmission, the water hammer elimination piston 54 inside the water hammer eliminater 53 slides under pressure. The three sealing gaskets 55 on its outside enhance the sealing performance, effectively buffer the water hammer impact, and protect the system components. The water that has undergone water hammer elimination treatment enters the booster tank 3 for further pressurization to meet the water transmission requirements of low head and long line. The pressurized water is output through the outlet pipe 6. The sensor inside the water pressure and flow detector 8 outside the outlet pipe 6 monitors the water pressure and flow in real time. If an abnormality occurs, the alarm will sound.
