Chapter 54 The problem is finally solved

The applause died down.

Everyone's eyes on Lin Feng were obviously different, especially Wang Tianfang, who obviously loved talents, and his eyes showed undisguised appreciation.

Of course, some people have doubts.

This is a senior engineer from the Engineering Technology Department. He asked loudly, "Gong Lin, did you really come up with this technical repair plan?"

It is estimated that many people have such doubts. After all, Lin Feng is too young, 24 years old, 25 years old should not have arrived yet.

Senior engineers like them, even professor-level senior engineers, can't come up with such a scientific and reasonable plan for a while.

Faced with such an inquiry, of course, Lin Feng could not say that it was given by the system, but he had already thought of an excuse, and replied loudly, "When I was in my senior year, I saw a similar receiver in the library of our school. There is not much difference between the repair data and this one, so I used it for reference.”

It turned out to be the case.

Although this cannot withstand scrutiny at all, it still silences everyone's mouths very well, and no one asks where this repair plan came from.

As for whether there is such a book in the university library, no one knows. Lin Feng said that there is, so it should be. Anyway, no one will check this matter.

Wang Tianfang didn't seem to want to ask about the source of the plan at all, and waved his hand, "I think this plan is very feasible. The sheet metal workshop will immediately copy the original version of the entire process, immediately compile a temporary process specification, and arrange the third welding test as soon as possible."

Wang Tianfang didn't want to delay any more, he just wanted to try as soon as possible, in case he succeeded, besides, judging from his professional level, the possibility of success should be very high.

But some people seemed worried. An expert from the Engineering Technology Department was very cautious, "Mr. Wang, the third welding test will be carried out immediately, isn't it a little sloppy?"

Wang Tianfang asked back, "Then what do you think we should do next?"

The expert said, "Be more careful, let's analyze and review again."

Wang Tianfang obviously didn't want to be so troublesome, time was tight, and the risk was worth it. In addition, he felt that although there were risks, they were probably not big, because he thought there should be no problem with this plan.

If there is any problem, you will know after the actual welding. Practice is the only criterion for testing the truth.

"Don't be so troublesome. The sheet metal workshop will issue a temporary process specification immediately, make preparations immediately, and start the welding test as soon as possible. I will bear any risks."

At this time, the courage as the chief engineer is undoubtedly reflected, so the arrangement is like this.

Hao Jiang, the technical director of the sheet metal workshop, quickly looked at his notebook and found that there were a few omissions. He quickly looked at what Lin Feng had written on the blackboard, but unfortunately some of the previous things had been erased.

Seeing this scene, Lin Feng said loudly, "Director Hao, I have a copy here, you can pick it up for reference."

Hao Jiang felt relieved, and immediately walked over a few steps to take the technical plan of Lin Feng's handwriting tablet. He flipped through it casually, and saw that it was very detailed with both pictures and texts, so he immediately felt relieved.

"Mr. Zhong, do you have anything to tell everyone?" Before announcing the end of the meeting, Wang Tianfang asked Zhong Zimin, after all, he was the representative of the General Army.

Zhong Zimin got up and said, "I have nothing to say, I'm waiting for your good news."

Wang Tianfang announced the adjournment of the meeting, and then a group of us went to the sheet metal workshop to start the third test.

Because two welding tests have been done before, everything is ready-made, and even the workers are the original two.

There is no need to compile the temporary process regulations. For special matters, the one on Lin Feng's handwriting board is used. Only a few related people signed on it, and Wang Tianfang personally signed and approved it.

The third receiver was brought over, and not long after, the operation started. In full accordance with Lin Feng's technical plan, the first step was to make an incision.

It’s just that the size and shape of this cutout is a little different from the previous two, it’s no longer a rectangle, but a triangle, and the position is also slightly different, more towards the front end of the combustion chamber.

The incision is made.

Immediately measure the size of the incision, Hao Jiang even asked, "Gong Lin, what do you think of this incision?"

Lin Feng smiled, a director as big as you actually asked me, a little new technician.

Although he felt a little funny in his heart, Lin Feng didn't show anything on his face, but said very politely, "I don't care. There are detailed requirements for the size and location of the incision. The inspector will know after measuring it."

The result came out quickly, the incision was qualified, and then the second step, then the third step, and the fourth step
Everything is strictly in accordance with the technical plan handwritten by Lin Feng, without the slightest deviation, every working step and every process parameter are basically consistent.

After more than an hour, everything was fixed.

The simulated oil leak has been welded, and the cutouts have been re-welded. After cooling, the combustion chamber case was moved onto the inspection turntable.

The answer is about to be revealed.

Some people found that they suddenly became a little nervous, worrying about the failure of the experiment, and some people were full of hope, whether it would succeed this time.

The turntable rotates slowly, and first finds the benchmark of the combustion chamber, while turning the combustion chamber, knocks with a wooden hammer to correct until the benchmark is found.

Then, under everyone's gaze, the inspector started to check the runout of the bearing hole with a dial gauge.

The surroundings became quiet, no one spoke, and no one made any noise, only some other voices from the workshop came.

The head of the dial indicator touches the inner wall of the turbine bearing hole, and the casing of the combustion chamber rotates slowly, and the head of the dial lightly passes over the inner wall.

"what!"

"See, the pointer jumps very little."

Originally, only one turn was enough. To be cautious, the inspector turned twice before stopping. The maximum jump of the pointer of the dial indicator was only a little more than two small divisions.

Fifty small squares in a circle, one small square represents two thousandths, more than two small squares, that is, a little more than four thousandths, it seems that it is less than five thousandths.

The inspector reported loudly, "Every leader, every expert, the beating is less than five thousandths, which is completely within the qualified range of the design."

It worked!
It turned out to be a success!
This surprise was really too great. In the previous two welding tests, the jump was the largest at seven or eight wires, and the best one was four or five wires. This time it was less than five thousandths.

If it weren't for a few other sizes to check, some people might not be able to help but celebrate, but most people can still see the joy on their faces.

Wuyou waved his hand, "Check the end face runout, hole diameter and other related dimensions immediately."

These dimensions were measured one by one, all qualified, this time the test was a complete success!

Wang Tianfang's tense nerves finally completely relaxed.
