Abstract:Objective To solve the problem that the water pressure of the central sterile supply center in
our hospital was non-constant, small or even out of water supply, the present study aimed to improve
the disinfection supply center water device so that the central high-pressure disinfection pot could work
stability, and ensured the needs of clinical departments and served clinical well. Methods The target
current switch, water level switch and pressure sensor of the water supply device separately transmit
their respective signals to their own programmable logic controller (PLC). The automatic frequency
conversion control was realized by PLC to achieve a constant water pressure in the whole line based
on transferring the frequency converter and booster pump by automatic operation. Results After the
improvement of the water circuit system of the central sterile supply center had been conducted, the
water pressure ratio of each water-using station was constant, and the high-pressure water pressure could
work normally, the water supply pressure and the water level could automatically control, which had
realized all-weather unattended automatic water supply. Conclusion The improved water device can not
only meet the needs of working water, but also improve the service life of the equipment. Meanwhile, it
can also save energy, save manpower and facilitate clinical work.
