冲洗油系统的作用是什么?

答案

参考答案:

分馏塔底玻璃液面计和回炼油缸坡坊液面度用冲洗油,重油易凝结,造成液面指示不准,用轻柴油冲洗溶解。回炼油缸和分馏塔底馏颁常温下均为固体,因而这两个部位的液面计中的油品在常温下也将凝固,无法看清容器内的真实液面,用冲洗液面计时,主要是冲洗油的压力和冲洗对凝结油品的溶解性能来实现的。

     It was a terribly rainy wet winter day.While I was walking from the library after getting

my University applications (申请) for next year at the end of my lunch break,a man was

walking towards me with two huge boxes of brochures (小册子).

     I thought,"What on earth is that man trying to do?Carry all those things?" Then all of a

sudden he dropped them all!It was a terrible mess with hundreds of brochures all over the

 path in front of me!"Oh,no," I thought.The man sat down and started trying to pick all

of the brochures up.I couldn't believe how many people walked on by without even

caring at all.

     I thought,"I'm not going to be one of those people who don't care about this man.I'm

going to help him."So,even though it was the end of my lunch break from work and I would

 be late if I stopped to help him,I didn't mind.If I explained what happened,I was sure my

boss wouldn't mind too much.So,I helped him pick them all up.Then I asked if he would

like a hand in carrying a box to where he went.He said yes gratefully.

     I carried one of the heavy boxes.The box I had to carry was very heavy-as I'm quite

a petite (娇小的) girl-but I didn't complain.I just helped him with a big smile across my

face.We got there and he thanked me very much for helping him out.He also gave me one

of these lovely brochures about all the walks in and around the Bay of Plenty.

     What is a better way to spend my lunchtime than helping someone?Luckily,I wasn't that

late back to work,so nobody minded at all!
