[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] A smart integrated full frequency constant pressure water supply system includes a box-type shell, an electrical control system, a booster pump set and a disinfection system. The box-type shell adopts a design process with noise reduction function, and different subsystems are configured from one shell.

[0031] As attached Figure 1As shown, the box-type housing is mounted on the channel steel base 108. Forklifts can operate through the forklift hole 109 during handling and transportation. Opening the front door 121 allows for direct pre-installation of the assembled pump unit. The electrical control system cabinet 120 on the box-type housing is embedded within it.

When the ultraviolet light source malfunctions, the second wafer-type butterfly valve 306 and the first wafer-type butterfly valve 302 are closed, while the third wafer-type butterfly valve 308 is opened to continuously replenish the fluid to the main inlet pipe of the booster pump group. The outlet pressure gauge 301 displays its outlet pressure value, providing a reference for maintenance personnel to troubleshoot anomalies on-site.
