进口水力喷射器是综合国内同类产品之优点革新制造的是一种具有抽真空、冷凝、排水等三种有效能的机械装置。其工作原理是利用一定压力水流通过对称均布成一定倾斜度的喷咀喷出，聚合在一个焦点上，由于喷射水流速度较高，于是周围形成负压使器室内产生真空。另外由于二次蒸汽与喷射水流直接接触，进行热交换，绝大部分的蒸汽凝结成水，小量未被冷凝的蒸汽与不凝结的气体亦由于与高速喷射水流互相摩擦，混合挤压，通过扩压管被排除，使器室内形成更高的真空。
Imported hydraulic jet is a comprehensive advantages of similar products manufactured innovation is a kind of three kinds vacuum pump, condensation, drainage, and other mechanical devices energy efficient. Its working principle is to use a certain pressure water flow through the symmetry cloth into a certain inclination are ejected nozzle, the polymerization in a focus, since the high speed jet of water, so the formation of negative pressure around so produce vacuum inside. In addition, as secondary steam injection in direct contact with the water, by heat exchange, most of the steam condenses into water, a small amount of uncondensed steam and noncondensable gas will also rub against each other and the high-speed water jet, coextrusion, by diffuser tube is excluded, thus to form a higher vacuum.

进口水力喷射器分铸铁和不锈钢两种材质，应用极为广泛，主要适用于真空与蒸发系统，进行真空蒸发、真空抽水、真空过滤、真空结晶、干燥、脱臭等工艺，是制糖、制药、化工、食品、制盐、味精、牛奶、发酵、酿造、轻工、国防部门广泛需要的设备。
Imported hydraulic jet of cast iron or stainless steel, wide range of applications, mainly used in vacuum and evaporation system, vacuum-evaporation, vacuum pumping, vacuum filtration, vacuum crystallization, drying, deodorization process, is the sugar, pharmaceutical, chemical food, salt, monosodium glutamate, milk, fermentation, brewing, light industry, and national defense equipment.
