1--How often do you service the pump?

2--We take very good care of this particular pump. It’s a crucial part of our process. We clean it and flush it through at the end of every shift, We check the high pressure seals, recalibrate the gauges and lubricate all moving parts weekly.

We replace the gaskets every month.

1-- How do you decide how often these things need to be done?

2--Well, from experience we can predict the lifespan of different components.

We try to replace components before they fail or wear out. This prevents the equipment from breaking down. It also saves us a lot of trouble!

譯文：

1--你們多長時間對這機泵車檢修一次？

2--我們對這種特殊的機泵進行非常好的維護。它是我們生產(chǎn)過程中一個很重要的部分。我們在每班結(jié)束時候都對其進行清潔沖洗。我們每周檢查高壓密封件,重新校正量表并對所有轉(zhuǎn)動的零件進行潤滑。

我們每月更換一次墊圈。

1--你怎么確定多長時間對這些件進行檢修一次？

2--哦,根據(jù)經(jīng)驗我們可以預(yù)計出不同零件的壽命。

在零件不能用或損壞之前我們盡可能對其更換。這防止了設(shè)備破壞。也為我們省去不少麻煩。
