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?guī)闳タ纯次覀兊膬艋O(shè)備嗎?設(shè)計(jì)的很巧妙。
2--是,我要看看。精確地說(shuō)它是清潔什么的?
1--它用來(lái)清洗掉像刀刃,托盤等所有金屬零件上的溶劑,然后送回系統(tǒng)去。
2--這個(gè)設(shè)備由什么組成?
1--哦,它主要由兩個(gè)罐,一個(gè)罐盛臟溶劑用的,一個(gè)盛清潔溶劑用的,一個(gè)機(jī)泵還有一個(gè)清洗裝置組成。哦,還有一個(gè)冷卻系統(tǒng)和一個(gè)過(guò)濾器。所有的這些都是由PLC系統(tǒng)(它代表邏輯處理控制系統(tǒng))控制的。
