我们设计制作了一种在医院制剂室应用的水力喷射器,这是一种具有抽真空、冷凝、排水三种效能的机械装置。经本院制剂室真空蒸发抽滤系统的多年应用,效果较好。一、结构与材料水力喷射器由器体、器盖、喷嘴、扩散管及止逆阀等部件组成(如图)。 We designed and manufactured a hydraulic injector for use in a hospital preparation room. This is a mechanical device with three functions of vacuum, condensation, and drainage. After many years of application of vacuum evaporation filtration system in the preparation room of this hospital, the effect is better. First, the structure and material The hydraulic injector consists of the body, cover, nozzle, diffusion tube and non-return valve and other components (pictured).
