稀油站的工作原理?

答案

参考答案:

稀油站工作时,工作油泵吸油管润滑从油箱内吸出,送入清除机械杂质的双筒网片或过滤器,经过滤后,油液沿管路送到冷却器进行降温,润滑下要求油温送到各润滑部位,润滑油在磨擦表面形成一层油膜,使物相对运动副得到润滑,并带走远动副间,磨损的金属微粒在回到邮箱,经过邮箱过滤,沉积降温反再由工作泵吸出就这样形成循环系统。

My friend Robert started a new job this week and he’s been in the training class for two days. The employer has a very strict dress code—dark blue shirts and pants.

On the first day, an older gentleman in his class did not have the proper clothes and he was strictly told that he would be fired if he didn’t have the right clothes the next day. He explained, “Sir, I had not been told about this. Because of my larger size, it’s sometimes difficult to find the right clothing for a price I can afford.”

Last night, Robert and I decided that this old man shouldn’t lose the chance of work simply because he couldn’t afford the clothes. I had some cash on hand and Robert took it with him this morning just in case it was needed.

When training started this morning, the trainer was ready to fire the older gentleman. “You have 10 minutes to be in proper clothes,” he was told. At this point, Robert spoke up and asked if he could have 10 minutes to get him the clothes. He then ran out to the store and bought the proper-sized pants and a shirt; he returned with both and gave them to the older man.

The older gentleman began to cry and told him that he couldn’t accept such a gift from a stranger. Robert told him he had to because he had lost the receipt(收据) and couldn’t return them—a little white lie. The pants were a perfect fit, the shirt was a bit tight but he was able to keep his job.

“My wife and I tried to gather together some money last night, but we didn’t have enough to buy the clothes,” he told Robert. “It’s unbelievable to me that anybody would do such a thing for only knowing me a day!”

More unbelievable is how good it has made Robert and me feel to do this.
