应用
- 当没有蒸汽可用作需要生成 40 到 5 毫巴真空的蒸汽喷射真空泵的动力介质时。
- 当液环泵的吸入能力足以处理空气喷射泵的动力空气，并且将生成低于 40 毫巴的吸入压力时。
- 当将要生成 40 到 5 毫巴的真空，并且低资金成本的简单安装非常重要时。
- 当仅需要在 40 到 50 毫巴的吸入压力下提供较小的吸入能力，并且可以在低温下获得冷却水时，因为在这些情况下，液环真空泵的能耗相对较低。
操作模式
空气喷射真空泵使用大气作为动力介质。凭借可生成 50 到 100 毫巴中等真空的液环真空泵，空气喷射真空泵可以达到 5 毫巴的吸入压力，具体取决于设计和操作条件。
只要是低能耗问题，就最好将带有冷凝器的蒸汽喷射泵连接到液环真空泵的吸入端，从而喷射泵的动力介质（蒸汽）会被冷凝且不会像空气喷射泵一样负载液环真空泵。
优势
- 无移动部件
- 无需维护
- 几乎可在所有情况下进行安装
- 快速轻松地投入使用
- 如果选择合适的材料，几乎没有寿命限制
- 可以使用各种材料制造
- 采购成本低

GEA 洞察
GEA reports profitable growth for 2025 and expects accelerated revenue growth
GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
How SmartParc is rewriting the rules of food production
Thanks to a new SmartParc manufacturing site, food processors in the U.K. are cutting their running costs and emissions. With GEA heating and cooling technology at its core, this collaborative production model demonstrates how innovation is accelerating the industry’s net-zero ambitions.
