当排水器贮水杯内水位未达到一定高度时,压缩空气的压力将浮球压下关闭排水孔,就不会造成气流泄漏;随着贮水杯内水位升高(此时冷冻式干燥机内并不积水),浮球上升到一定高度便打开排水孔,杯内凝结水在气压作用下很快排出机外。

When the water level in the water cup of the drainer does not reach a certain height, the pressure of compressed air will depress the floating ball and close the drain hole, which will not cause air leakage; as the water level in the water storage cup increases (at this time, there is no water in the freezing dryer), the floating ball rises to a certain height and the drain hole will be opened, and the condensed water in the cup will be discharged out of the machine quickly under the action of air pressure.

凝结水排尽后浮球又在气压作用下关闭排水孔。所以自动排水器是一种节能器。它不仅在冷冻式干燥机中得到应用,而且在贮气罐、后部冷却器及过滤器等多种气源处理设备上都得到广泛应用。

After the condensate is drained, the floating ball will close the drain hole under the action of air pressure. So the automatic drainer is an energy-saving device. It is not only used in freeze dryer, but also widely used in many kinds of air source processing equipment such as air storage tank, rear cooler and filter.

除了常用的浮球式自动排水器外,还经常使用电子自动定时排水器,这种排水器的排水时间及两次排水的时间间隔都可调整,而且能耐较高压力,应用也很普遍。

In addition to the commonly used floating ball automatic drainer, electronic automatic timing drainer is often used. The drainage time and the time interval between two times of drainage can be adjusted, and it can withstand high pressure, so it is widely used.

自动排水器的数量与位置如何确定?

How to determine the number and location of automatic drainers?

自动排水器的一次排水量是有一定限度的。如果在同一时间里冷冻式干燥机凝结水的生成量大于自动排水器的排水量,那么机内就会有凝结水积存。时间一长,凝结水会越聚越多,因此在大、中型冷冻式干燥机中,往往要装两只以上的自动排水器,以保证机内不积存凝结水。自动排水器应安装在预冷器和蒸发器的下游,常见的是直接装在气水分离器下方。

There is a certain limit to the primary displacement of the automatic drainer. If at the same time, the amount of condensate generated by the freezing dryer is greater than that of the automatic drainer, then there will be condensate accumulation in the machine. As time goes on, condensate will accumulate more and more. Therefore, in large and medium-sized freeze dryer, more than two automatic drainers are often installed to ensure that there is no condensate accumulation in the machine. The automatic drainer should be installed downstream of the precooler and evaporator, usually directly under the gas-water separator.
