电热蒸馏水器由于其结构简单、使用方便制水质量可靠,在基层医院制剂室普遍使用。但也常因使用方法欠妥,致使电热管被烧坏,现根据我们的实践体会谈谈如何防止损坏电热管。 1.必须等蒸发锅内水位上升到玻璃水位眼处再通电,电源电压必须正常,应在不超过±5%的范围内使用,如电压过高,易使电热管损坏。过低则影响蒸馏水出水量;有条件的单位可以装稳压器,使输入电源电压稳定。
Electric water-distilled water heaters are widely used in the preparation rooms of primary hospitals because of their simple structure and easy-to-use water quality. However, due to the improper use of the method, the heating tube is burned out. According to our practice, we will discuss how to prevent damage to the heating tube. 1. The water level in the evaporation pan must be raised to the level of the glass level and then turned on. The power supply voltage must be normal and should be used within a range of not more than ± 5%. If the voltage is too high, the heating tube is easily damaged. If it is too low, the amount of distilled water will be affected. A conditional unit can be equipped with a regulator to stabilize the input power supply voltage.
