抽气

The condensing equipment consists of condenser, cooling pump, air ejector and condensing pump.

凝汽设备由凝汽器、冷却水泵、抽气器和凝结水泵组成。

Therefore, with the low load, the extra air must be extracted to ensure the minimum pressure of condenser, indicating that the air ejector must be capable of extraction with a low condenser pressure.

这意味着，在较低的凝汽器压力下，抽气器要有抽出更多空气的能力。

The existing determining method of the optimum vacuum of condenser is only fit for the condition of that condenser is clean in tubes and vacuum system tightness is up to standard or the performance of air ejector is normal.

现有的凝汽器最佳真空的确定方法只适用于凝汽器水侧管壁清洁、汽轮机真空系统严密性正常或抽气设备运行性能正常的工况。

Additionally, the air cooling zone should be set up so as to cool the steam and air mixture. Thus, the steam and air mixture supercooling can be enlarged, the working medium loss reduced and the burden of air ejector taken away.

另外，应该设置空气冷却区，使蒸汽-空气混合物得到冷却，以增大排出的蒸汽-空气混合物的过冷度，减少工质损失，并降低抽气器的负荷。

Generally, the air leakage in condenser can be attributed to tube and valve imprecision of vacuum system or deficiency or even intermittence of steam seal pressure. Besides, it is probably engendered by low-efficient air ejector, which cannot totally extract the air leakage in condenser.

空气漏入凝汽器的原因，通常是由于真空系统管道阀门不严密或汽封压力不足甚至中断所造成的；也可能由于抽气器效率降低，不能将漏入凝汽器的空气完全抽出而造成的。

An air-evacuation packaging mechanism is applicable to package a barrier bag and an inner filler material enclosed by the bag, and comprises an air-evacuation apparatus, a clamping apparatus and a thermal sealing apparatus.

一种真空封装机构系应用於一袋体及一置於该袋体内的芯材之封装，其包含一抽气装置、一压合装置及一热封装置。

At the appropriate pressure, the chamber is opened to a high-vacuum pumping system that continues to reduce the pressure of the process chamber.

在适当的压强下，工艺室被接通高真空泵系统抽气，以继续降低工艺室的压强。
