通常牙科综合治疗机漏水故障都发生在水路系统。主要原因是接口松动,橡塑管老化等,现象直观,也易排除。今年检修到一例S2301型牙科综合治疗机气路漏水故障,现总结,与同行交流。 水从脚开关漏出,脚开关是气控常通阀,气控常通阀漏水,本文就称为气路漏水。查,脚开关是好的,但脚一踏上水就向外渗,此现象说明气中有水。水是如何混入气路的呢?经反复检查,拆开脚开关控制的被控阀,发现漏水原因为:上层的卡布龙绸垫有微小的裂纹。上层卡布龙绸垫的作用为控制水的通断,下层卡布龙绸垫的作用为控制气的通断。
Usually the leakage of dental treatment machines occurs in the waterway system. The main reason is that the interface is loose, and the rubber tube is aging. The phenomenon is intuitive and easy to eliminate. This year repaired to a case of the S2301 dental treatment machine air leakage fault, is summarized, and exchange with peers. The water leaks from the foot switch, the foot switch is the air control normally-pass valve, and the air control normally-pass valve leaks. This article is called the air leakage. Check, the foot switch is good, but the foot goes out as soon as you step on the water. This phenomenon shows that there is water in the air. How was water mixed into the airway? After repeated inspections, the controlled valve of the foot switch was dismantled and the cause of the leak was found to be: the upper layer of the tarpaulin was slightly cracked. The role of the upper calburo mat is to control the on and off of water, and the role of the lower calponon mat is to control the on and off of the gas.
