The eighth day of the first month.

All employees of Tianfeng Technology Company officially went to work, and on the first day of work after the Spring Festival, the entire Tianfeng Technology Company was festive, and everyone could feel a strong festive atmosphere.

At the gate of the company, the red lantern was hung high, the long huge red banner, the fluttering colored flag, the whole festive completely set off, Li Tianfeng, Sun Kang and others stood neatly at the gate to welcome the employees on the first day of work.

The employees who went to work obviously felt this kind of festivity, and everyone was happy and energetic, and walked into Tianfeng Technology Company in groups.

At 8:08 a.m., the fireworks were in full bloom, and the joy of the whole work was pushed to the top, this year, in order to have a good fortune, hoping that his first engine could come out smoothly, Li Tianfeng spent more than 100,000 yuan, and bought a large number of fireworks.

According to the usual practice, in the morning, Li Tianfeng and Sun Kang and others visited various departments of Tianfeng Technology, and in the afternoon, Li Tianfeng also had to go to the E factory to visit Zhu Maohua, Yang Xianfeng and others, which is the custom of the Chinese people, and Li Tianfeng is not exempt from vulgarity.

For the employees, in addition to clearly feeling the festive atmosphere and full of joy and joy, everyone is also looking forward to getting a big red envelope today.

"Lao Zheng, I remember that last year's red envelope was 600 yuan, I don't know how much it is this year?"

"Lao Zhang, according to the generosity of the boss, this year will only be more, not less."

Many old employees of Tianfeng Technology still remember the thick red envelope last year, and last year, it was the red envelope that they got that kind of red envelope, and everyone was happy for a while.

In a city like Songzhou, on the first day of work after the Spring Festival, even if they give red envelopes to employees, it is often 100 yuan. Enterprises that send 200 yuan red envelopes are polite, and a few stingy companies give 50 yuan red envelopes, or even do not send them.

Some of the new employees listened to some old employees happily talk about last year's red envelopes, and their interest immediately came up.

I saw a young employee gently holding an old employee. asked in a low voice: "Lao Zhang, did you really give out a red envelope of 600 yuan last year?" ”

Lao Zhang waved his hand and said happily loudly: "No, last year's red envelope was six red hundred-yuan bills, how comfortable it looks, my Lao Zhang was happy to receive the red envelope for a whole week." ”

"Not really. I'm the same, I've been happy for days, and I've been full of energy to go to work for a few days. Another veteran employee next to him said.

Suddenly, many employees looked forward to it!

My own department manager, walked into the big office. Seeing that everyone was talking about the red envelope, he couldn't help but smile, waved his hand, and said happily: "The red envelope is here, everyone has a share." ”

Seeing that his manager was holding a large stack of red envelopes in his hand, everyone immediately gathered around happily and looked at these red envelopes in his manager's hand with bright eyes.

This department manager is just like everyone else. Very happy, took out a list, and said loudly: "Sign a name and get a red envelope." Come one by one. ”

Suddenly, everyone came up to sign one by one, happily received their own red envelopes, and some employees immediately opened them as soon as they got the red envelopes, and pulled out a thick stack of red hundred-yuan bills from it.

One sheet. Two, three......

"Wow. Rich, rich!! ”

"Wow. A full 800 yuan, two hundred more than last year! ”

A young beauty wearing glasses opened the red envelope, jumped up happily, and said exaggeratedly: "The boss is so generous, I like it!" I love you to death! ”

The whole Tianfeng Technology, there are currently more than 3,000 people, regardless of position, regardless of the type of work, all got a big red envelope of 800 yuan, many employees are psychological, grateful to Li Tianfeng, and the work is also full of vitality and enthusiasm.

After the New Year, Tianfeng Technology was happily opened under such circumstances, starting this promising year, according to the plan, Li Tianfeng will assemble his first verification machine this year, and will conduct a series of verification tests.

After a good start, more than 3,000 employees of Tianfeng Technology are full of passion and enthusiasm, and the work is also carried out in an orderly manner.

………

Tianfeng Technology, final assembly workshop.

Now the assembly workshop, all the hardware facilities are in place, and even the turboshaft engine assembly bench has been installed, because the turbineshaft is not big, the assembly bench is not big, and it is not complicated, so the progress is relatively fast, now, the ten assembly benches are all completed, lined up, and the assembly operation can be carried out at any time.

Of course, before the final assembly of the engine, it is necessary to assemble the various components, and after the assembly of each component, the overall assembly of the engine is carried out on the assembly bench one by one.

The assembly of various components is naturally carried out in the assembly workshop, and there is a special assembly area for the components of the "TFWZ001" turboshaft engine, and then the assembly area, which has a total of ten "TFWZ001" turboshaft engine assembly benches.

The assembly workshop is very large, much larger than the No. 1 workshop and the No. 2 workshop, covering an area of more than 18,000 square meters, which is very domineering.

Huge assembly workshop, the ground is spotless, this is a dust-free assembly workshop, constant temperature, constant humidity, the ground is smooth and clean can illuminate the figure, enter the workshop, to change shoes, put on snow-white cotton slippers.

The assembly area and assembly area of the "TFWZ001" turboshaft engine, the assembly area, plus the parts inspection area and the related test area, only occupy less than one-third of the entire huge workshop, and the remaining area is empty.

These open areas, tens of thousands of square meters, which are reserved for the assembly of the rest of the engines in the future, Tianfeng Technology, it is impossible to only develop and produce the "TFWZ001" type of aero engine, in the future, there may be turbofan engines.

In such an empty area, just kidding, there are enough places for the employees of the assembly workshop to have an all-staff sports meeting.

The assembly workshop was put into use, and some parts of the turboshaft engine of the "TFWZ001" type could also be assembled, and some employees were assembling the parts, such as turbine rotor assembly, combustion chamber assembly, compressor assembly, etc.

Accessories inspection area, the area is not small, a large inspection table, neatly arranged, this is a professional inspection desk, each table has a thick layer of green rubber, can prevent parts from scratching.

Before the assembly of an aero engine, a large part of the inspection work is absolutely different from the general mechanical assembly.

The general mechanical product assembly we have seen is generally to bring qualified parts, take it and start assembling it, and always assemble it into a mechanical product that meets the requirements, but the aero engine assembly is definitely not so simple.

Even if you receive a good part, you should never rush into assembling it right away, as there is a lot of work to be done before assembly.

Inspection work is one of the important tasks. After the production task is assigned, the distributor sends the parts and accessories to the inspection area, and the inspector starts his work.

First, some assembly size items of the part are checked again to measure the measured value, of course, the non-assembly size is generally not repeated. After the measurement is completed, it is necessary to carry out the selection, because there are some parts with strict requirements, and it is definitely not possible to match without selection.

Li Tianfeng personally came to the assembly workshop today, and changed into the special snow-white cotton slippers at the entrance of the assembly workshop, the shoes are very light, very thin, and very comfortable to wear.

Although the assembly workshop did not meet the high standards of dust-free electronic product assembly, it also had its own dust-free requirements.

Entering the assembly workshop, the first feeling at a glance is that the workshop is very large, very large, nearly 200 meters in length, nearly 100 meters in width, it looks very domineering, very magnificent.

Li Tianfeng nodded with satisfaction, walked into the assembly workshop, and saw that some workers were already working, and some accessories were also delivered to the assembly site, and the preparation work was done well.

Walking to the parts inspection area, Li Tianfeng saw an inspector measuring the journal of a turbine shaft, and next to it, there were several bearings, which would be assembled on the turbine shaft, and the assembly part was the journal of the turbine shaft.

These bearings are purchased from domestic professional aviation bearing factories, an aero engine, tens of thousands of parts of various types, Tianfeng Technology can not produce any parts by itself, on the contrary, many parts are purchased from home and abroad.

Li Tianfeng looked at the side, and the actual size of the inner bore of these bearings was measured, accurate to three decimal places, that is, one thousandth, and the measurement of the shaft journal was basically the same.

There is an assembly relationship between the two, and the assembly drawing requirements are interference fit, and the interference amount is 0.006 to 0.015, and the requirements are relatively strict. Interference fit, in layman's terms, means that the hole and shaft are assembled to a certain tightness.

There are strict requirements, especially for aero engines, this tightness is very strict, such as the assembly of the above bearings and turbine shafts, interference 0.006 to 0.015, very strict.

Even if it is very strict, but it is necessary to try to choose, to achieve the best difference, such as the above interference 0.006 to 0.015, the best is about 0.010, which is to choose the bearing and turbine shaft. Once selected, they are paired and assembled by the assembler.

Li Tianfeng did not express his opinion, stood aside, just said a simple hello to the inspector, and then watched the inspector work, Li Tianfeng also took a look at how the inspector was selected, whether it was matched according to the difference, and the interference was matched at about 0.01.

Today, the third watch will continue, and the third watch will be sent!!

It's the third watch again, do you have a monthly pass to support it? (To be continued) R466
