热压灭菌柜使用中往往出现温度表指示的温度上升很慢,与蒸汽压力表的压力不对应。笔者经实践体验,认为有下列问题应引起注意: 1 产生上述情况主要原因是内锅排冷凝水冷空气管道不畅通,排出速度缓慢。灭菌中锅内已达较大压力,而尚有部分冷空气未及排出,使锅内成为非饱和蒸汽压力,温度局部不一。装在排水管道内的温度表的“感温管”因介于冷凝水与冷空气或部分蒸汽的混合体中,温 The temperature rise indicated by the temperature meter often occurs during the use of the hot-press sterilization cabinet, and does not correspond to the pressure of the steam pressure gauge. According to the experience of the writer, I believe that the following problems should be paid attention to: 1 The main reason for the above situation is that the cold air pipes in the condensate of the inner pot are not smooth and the discharge speed is slow. Sterilization in the pot has reached a greater pressure, and there is still part of the cold air discharge, so that the pot becomes unsaturated steam pressure, the temperature is not the same. The “temperature sensor” of the thermometer installed in the drainage pipe is located in the mixture of condensed water and cold air or part of the steam.
