摘要
目的为解决我院消毒供应中心各个用水点水压不恒定,水量小甚至时常停水的问题,该研究对消毒供应中心用水装置进行改进,从而满足该中心高压消毒锅能正常工作,保障各临床科室的需要,更好地服务于临床。方法通过靶流开关、水位传感器、压力传感器分别对逻辑控制器(Programmable Logic Controller,PLC)传递各自相关的信号,PLC通过自动运算处理后向变频器、增压泵传递是否工作的指令,从而实现全自动变频控制,使整套管路达到恒定的水压。结果通过对消毒供应中心水路电路系统的改进后,各用水点水压比没改之前恒定,高压消毒锅也可以正常工作,供水压力和储水箱液位能自动控制,实现了全天候无人值守自动供水。结论改进后的用水装置,既满足了工作用水的需要,又提高了设备的使用寿命,既节约了能源,又节约了人力,方便了临床工作。
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.
