The lifting process of the sound-proof shield is as follows: the piston rod of the telescopic cylinder 317 provides thrust for the connecting plate 315 through the thrust shaft seat 316, the connecting plate 315 is pushed to move upwards, the connecting plate 315 drives the lifting plate 314 to ascend along the vertical rail 313 on the supporting rod 312, so as to drive the sound-proof cover 310 to ascend, the digital variable frequency pump 301 in the sound-proof cover 310 is exposed, and the sound-proof cover 310 can be arranged in a lifting manner, so that noise generated in the working process of the digital variable frequency pump 301 can be effectively isolated, meanwhile, when the digital variable frequency pump 301 needs to be overhauled, the sound-proof cover 310 ascends to meet the overhauling work of the digital variable frequency pump 301, and from sound insulation to overhauling, the sound-proof cover 310 does not need to be manually moved and; the damping process of the digital variable frequency pump and the steady flow tank is as follows: when the digital variable frequency pump 301 pumps water from the steady flow tank 100, the steady flow tank 100 drives the support frame 101 to shake, and the digital variable frequency pump 301 shakes itself, so as to drive the heightening plate 306 at the bottom to move up and down along the groove on the inner wall of the plastic spraying base 307, the arrangement of the pressure spring 318 reduces the displacement amplitude generated by the heightening plate 306, the rotating rod 322 on the clamping plate 323 rotates when the support plate 319 moves up and down, so that the rotating rod 322 drives the air spring rod 321 on the slot 320 to stretch, and the support plate 319 presses the spring sleeve 325 on the fixing rod 324, the fixing block 326 supports the spring sleeve 325, the arrangement of the air spring rod 321 and the spring sleeve 325 reduces the displacement amplitude generated by the support plate 319, so as to reduce the vibration amplitudes of the digital variable frequency pump 301 and the steady flow tank 100 on the heightening plate 306 in a matching manner, so that the reliability of the digital variable frequency pump 301 and the steady flow tank 100 is higher, meanwhile, the situation that water leaks at the joints of the second water pipe 501, the connecting pipe 305 and the digital variable frequency pump 301 due to long-term use and shaking of the digital variable frequency pump 301 is effectively avoided; the water supply process of the system is as follows: the non-negative pressure electrical cabinet is in an automatic state, when the remote transmission pressure gauge 400 detects that the pressure of a public water supply network at the position of the first water pipe 401 is larger than or equal to 0.2Mpa, the time is delayed for 10 minutes (the time is adjustable), the PLC in the non-negative pressure electrical cabinet 800 opens the first valve 500 and the second valve 600, an external water source supplies water into the water tank 200, and the external water source supplies water to the flow stabilizing tank 100 through the first water pipe 401. The PLC controller closes the third valve 700, the digital variable frequency pump 301 pumps the water in the steady flow tank 100 through the second water pipe 501, and discharges the water to the water outlet pipe 302 through the connection pipe 305, and the water outlet pipe 302 directly supplies water to the floor. When the PLC controller detects that the water tank 200 reaches the high water level, the second valve 600 is closed. When the remote pressure gauge 400 detects that the pressure of the public water supply network at the position of the first water pipe 401 is less than or equal to 0.2Mpa (0.2-0.4 Mpa can be freely set), the PLC controller in the non-negative pressure electrical cabinet 800 closes the first valve 500, opens the second valve 600, opens the third valve 700, closes the digital variable frequency pump 301, supplies water to the water outlet pipe 302 through the fourth water pipe 701, and the water outlet pipe 302 directly supplies water to the floor. When the remote pressure gauge 400 detects that the tap water pressure at the position of the first water pipe 401 is always stable, the non-negative-pressure water supply mode and the box-type water supply mode can be switched at regular time. The water stored in the water tank 200 is circulated at regular time through intelligent control to ensure fresh and pure water quality.
Referring to fig. 1 to 8, the working process of the box-type non-negative pressure automatic switching variable frequency water supply system of the present embodiment is as follows:
the steady flow tank 100 is arranged on the support frame 101, the support frame 101 and the variable-frequency constant-pressure water pump unit 300 are both arranged on the heightening plate 306, and through the arrangement, the steady flow tank 100 and the digital variable-frequency pump 301 are both arranged on the heightening plate 306, so that the floor area of the whole variable-frequency water supply system is effectively reduced;
the sound-proof housing 310 can be lifted, so that noise generated in the working process of the digital variable frequency pump 301 can be effectively isolated, meanwhile, when the digital variable frequency pump 301 needs to be overhauled, the sound-proof housing 310 is lifted to meet the overhaul work of the digital variable frequency pump 301, and from the sound insulation to the overhaul process, the sound-proof housing 310 can be lifted without manual moving and can be completed through the telescopic cylinder 317;
