I Have a Research Support System

Not long after Wu Feifei left, she brought a water pump and came with Teacher Wei. Duan Yun and Chen Wanqing were also called by Teacher Wei.

However, because of the small space around the circulating water system, other people can only watch outside.

How is the situation now? I heard from Wu Feifei that there is a water leak? Wei Xingsi said seriously.

It seems that there is no serious problem at present, Xu Qiu said:

It's the water outlet of the circulating water that is dripping. Now we need to drain the water in the water storage tank first, then deal with the accumulated water on the ground, and finally find a way to repair it.

That's fine, let's see if we can fix it ourselves, Wei Xingsi said:

If it doesn't work, Wu Feifei, please contact their equipment manufacturers and see what they say.

The water pump in my fish tank will be used in the laboratory, and I will buy a new one later.

Teacher Wei looked at it and felt that he couldn't help much, so he said:

I'll go back first, remember to tell me after you've dealt with it.

Wu Feifei handed the water pump to Xu Qiu.

Xu Qiu put one end of it into the bottom of the circulating water storage tank, and inserted the other end into an empty waste liquid bucket, then connected the power supply and started pumping water.

The water drawn out was a bit cloudy and yellowish brown, but it had no pungent smell.

After pumping out all the water, Xu Qiu stepped on the toilet paper and started mopping the floor.

The space here is small, and the mop cannot be opened, so paper is the best choice.

In fact, the paper in the laboratory is the universal rag.

It is cheap and can be thrown away after use.

After dealing with the scene, Xu Qiu used garbage bags to collect the toilet paper.

Then, he squatted down and checked the water outlet carefully, and found that the leak was the connection between the water storage tank and the water outlet pipe.

There was a rubber ring on it, Xu Qiu pulled it with a little force, and it broke.

Xu Qiu held up the broken rubber ring and asked:

Does this kind of rubber ring still exist in the laboratory?

Wu Feifei took a look and said:

It should be there. I'll look for it in the toolbox.

While waiting, Xu Qiu entered the simulation laboratory.

There is no space limitation here, and the entire circulating water system can be inspected more conveniently.

He first checked the pipeline of circulating water, starting from the water outlet of the water storage tank, passed through a diverter, diverted into three pipelines, reached two glove boxes and molecular pumps respectively, and finally joined the water storage tank at the diverter water intake.

It seems that the circulating water system originally designed was not only for the heat dissipation of the molecular pump, but also took into account the heat dissipation of the glove box. However, they almost never used this function.

Just when Xu Qiu was about to check the pipeline of the molecular pump, he felt something hard poking him.

He switches consciousness back to reality.

Xu Qiu, are you okay?

It turned out that the senior sister was testing him with a long wooden stick when she saw that he had remained motionless.

Maybe they thought I got an electric shock, Xu Qiu thought to himself.

It's okay, I was just thinking about the cause of the water leakage here.

I found the same style. After Wu Feifei finished speaking, she handed over a rubber ring.

Xu Qiu put it on and said, Try to see if it still leaks.

Under Wu Feifei's instruction, Duan Yun brought the bucket of deionized water.

Xu Qiu first added a small amount of water so that it just covered the pipe of the water outlet, and waited for more than ten seconds, but no water leaked.

Then, he filled the water storage tank to half full, and waited for more than ten seconds, but there was still no water leakage.

Only then did he feel relieved to fill up the water storage tank.

Xu Qiu started the machine, checked again that there was no more water leakage, and then exited.

But he had a faint feeling that something was wrong.

Great, we can continue the experiment today. Wu Feifei said:

If the circulating water is not repaired well, my batch of devices will be in vain.

Xu Qiu found an excuse to go to the toilet, entered the simulation laboratory, and continued to check the pipes of the circulating water system.

The water pipes are made of hard transparent rubber pipes, and the pipes are deliberately hidden. They are all at the bottom of the glove box, and usually no one will notice.

He found that the water in the water pipe was turbid, and there were some flocculent substances hanging on the inner wall.

Xu Qiu began to analyze:

There are metal parts in the pipeline. Although it may be made of stainless steel, it will also produce rust if it is soaked in water for a long time.

Because the water is not changed for a long time, rust, dust, oil and other substances will form flocculent precipitates with the circulation of water, and adhere to the inner wall of the water pipe.

As a result, the diameter of the inner wall of the water pipe is reduced, and the water pressure is increased. Finally, the rubber ring at the joint is subjected to excessive pressure for a long time, and the material fails, resulting in water leakage.

Thinking of this, Xu Qiu understood that the operation of changing the water just now was only a temporary solution, not a permanent cure.

The most direct way to completely solve this problem is to replace the water pipe with a new one.

However, the water pipes are buried inside the glove box and the molecular pump, so it is too difficult to replace them.

Then the compromise method is to clean the water pipes and change the water through multiple cycles so that the entire pipeline is filled with deionized water.

He is also fortunate that the water leakage incident did not happen inside the molecular pump or the glove box, which may cause damage to the instrument due to water ingress.

The next time may not necessarily have this good luck.

Xu Qiu returned to the laboratory and said:

Wu Feifei, stop the experiment first, the problem has not been completely solved yet.

What's the matter, isn't it leaking? Wu Feifei said.

It's true that there is no water leakage, but there are still hidden dangers. Xu Qiu explained his reasoning process to her in detail.

It sounds reasonable. It seems that the circulating water needs to be replaced regularly. Wu Feifei said:

But my experiment, if this batch of devices continues to be tossed like this, it will probably be cold.

Wu Feifei reluctantly turned off the evaporation equipment again.

Xu Qiu returned to the circulating water system and found that the water in it had become muddy again, but it was better than the first time.

He pumped the water out and refilled it with deionized water half the volume.

After fifteen minutes of circulation, vacuum again.

Repeated three times, the circulating water is basically clear, and the water in the pipeline is also clear, indicating that it has been almost cleaned.

However, the deionized water in the laboratory was also used up by Xu Qiu.

Should it be done this time, Xu Qiu? Wu Feifei asked a little uncertainly.

She was afraid that she would be forced to stop working again when the experiment was half done.

No problem, it's just that the circulating water is only half, and it will be added later, but it's enough for your experiment.

That's good, Wu Feifei clasped her hands together, closed her eyes, and prayed:

This batch of devices must be done well, and must be done well, otherwise there will be no data for my group meeting.

This Wu Feifei is a bit interesting, the metaphysics experiment method.

Xu Qiu smiled, turned to Chen Wan and said:

Sister, where can I get deionized water?

Our department doesn't have one. I'm going to fetch water from the chemistry department. Shall I go now? Chen Wanqing said.

OK.

Ask for a recommendation ticket. Thanks to Lanzang Wenyuan for the 500 point reward.
