Rebirth of Northern Technology

"What if we equip two more sets of parts, after three months, replace the rotating parts and the whole set?"

Cheng Yongxing proposed a temporary plan.

"But in this way, the entire cavity has to be cut open and then welded back. This workload can be heavy. Moreover, once disassembled and assembled, the whole thing will be discarded if it fails!"

Wang Gong disagrees with this approach, because the tone is embodied in an integrated design, and he has never considered this situation.

"What if we completely modify the cavity design? Make this part of the motion component a separate module, and then easy to disassemble?"

Cheng Yongxing regretted it and adopted the rotary heating scheme. At that time, this scheme was adopted to prepare for subsequent continuous production.

In that advertising video, this set of rotary heating solutions is being promoted. Since the heated workpiece, that is, the wafer, is continuously rotating above the heating unit, the heating is even. It is also conducive to other reactions, with high output quality and good consistency.

The animation on the video is very simple, and the drawing design is not complicated, but the requirements for parts are relatively high.

"Modify the cavity design? Just to disassemble and replace the rotating mechanism? Yes, but there is no time! Starting from the modification of the design, the whole process will take at least two months."

Everyone sitting here has been suffering from these quality problems recently.

The gap in the level of equipment manufacturing cannot be made up by creativity.

————————

"Wang Gong, can you guarantee a three-month service life in this working condition?"

"It can be guaranteed."

"That's all right! This one is just like that, the design doesn't change, start to assemble. Test!"

Cheng Yongxing has no ability to solve technical problems, but can solve business problems.

"Xiaocheng, aren't you kidding me, just three months for the equipment of seventy to eighty thousand yuan?"

Everyone was taken aback by this conclusion. I know that this is a representative of Party A, but this posture, this young man, is a plenipotentiary representative!

"No kidding! I don't have time."

Cheng Yongxing’s bottom line is the papers and patents, which must not be delayed until 1991. Because since March of 1991, the papers of the great man opposite have been published one after another.

Considering the advance amount of patent applications, the end of this year, that is, the end of 1990 is the bottom line.

It is time to spend money to buy time, and let's talk about the public money, it doesn't hurt to spend it.

"You have no time? Xiaocheng, I heard you right! This device is for you alone?"

The identity of a young person has evolved from a plenipotentiary representative to Party A himself.

"Yes! You did not understand it wrong! You can call to confirm this information at any time! The entire laboratory, to be honest, was built for me!"

Cheng Yongxing can only cut the mess with a sharp knife. This kind of thing is unclear at all, so just let it go.

"Then, is this equipment like that? Let's start assembling?"

No one on the table saw him as a student.

————————

"This equipment, we have to prepare with both hands."

Cheng Yongxing has to keep a back hand. You can't use it for a while.

"Which hands?"

"The first station, due to time constraints, can only do this. There is no alternative. But the next station can't!"

"Next, are you going to buy another one?"

The people in the room were almost stunned.

"Yes! This equipment will be put into use around the end of August. Three months later, which is November. Then its replacement should be delivered before the end of October."

Due to the localization of the equipment, there is still a surplus in the budget. Domestically produced goods are of high quality, but they are cheap and they are definitely qualified.

"Okay, okay, there is no problem!"

Section Chief Wang nodded repeatedly.

How great is this!

It seems that the product has a short lifespan, which has the advantage of a short lifespan.

The design ideas for things that were sold before were wrong!

The direction is wrong, the opposite is true! The factory leaders have the responsibility to reach the point where the factory is today!

————————

"But I request that, for this one delivered at the end of October, the life issue of the sports components should be solved. I have a suggestion, Wang Gong, Gao Gong, you can help me to see if it is feasible.

"Okay, say Xiaocheng!"

Everyone in the room is interested.

"The temperature in the reaction chamber is too high, and the working environment of the moving components is bad. But can we use a sub-cavity method to separate their environment from the main cavity. In this sub-environment, you can add some heat sinks to it? To lower the temperature of this small environment."

In a high temperature environment, every degree of decrease is meaningful. For example, the lubricating oil, which is very common under normal temperature conditions, is difficult to find when it reaches thousands of degrees. Even if it can be found, it is expensive.

"Yes! Xiaocheng, you young people are smart. According to your idea, we can even make an external cavity!"

The senior engineer was inspired and took his ideas one step further. When he shouted so, everyone in the room understood, and the atmosphere immediately became warm.

"Xiaocheng, that's it!"

Wang Gong lay on the table and gestured for a long time, and finally threw the pen away and agreed to the outer cavity plan. The problem of poisonous gas leakage that everyone is worried about can be solved with one pack of the cavity.

The main body of the moving component is outside the reaction chamber, although due to heat conduction and gas exchange, the temperature of the outer chamber may reach more than one hundred degrees. But this point of temperature, for sports machinery, has been regarded as the normal working temperature.

Once the main problem is solved, all that is left is the corners and corners.

A group of people are busy with work and entertaining.
