1--Would you like me to show you our new cleaning unit? It's a clever design.
 
2-- Yes, I'd like to see that. What does it clean exactly?
 
1-- It washes the solvent off all the metal parts - the blades, trays etc. - and then sends it back into the system.
 
2--What does the unit consist of?
 
1--Well, it’s basically two tanks – one for the dirty solvent and one for the clean solvent a pump and a washing unit. Oh, and there’s a cooling system and a filter. It‘s all controlled by a PLC system – that stands for Process Logic Control.

1--要我带你去看看我们的净化设备吗？设计的很巧妙。
2--是,我要看看。精确地说它是清洁什么的？
1--它用来清洗掉像刀刃,托盘等所有金属零件上的溶剂，然后送回系统去。
2--这个设备由什么组成？
1--哦，它主要由两个罐，一个罐盛脏溶剂用的，一个盛清洁溶剂用的，一个机泵还有一个清洗装置组成。哦，还有一个冷却系统和一个过滤器。所有的这些都是由PLC系统(它代表逻辑处理控制系统)控制的。
