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!

1--你们多长时间对这机泵车检修一次？

2--我们对这种特殊的机泵进行非常好的维护。它是我们生产过程中一个很重要的部分。我们在每班结束时候都对其进行清洁冲洗。我们每周检查高压密封件,重新校正量表并对所有转动的零件进行润滑。

我们每月更换一次垫圈。

1--你怎么确定多长时间对这些件进行检修一次？

2--哦,根据经验我们可以预计出不同零件的寿命。

在零件不能用或损坏之前我们尽可能对其更换。这防止了设备破坏。也为我们省去不少麻烦。
