Chapter 983 Clean Room
The three of Duan Yun came to the newly approved 60 mu of industrial land.

At this time, the industrial land had been connected with the electronics factory by a fence, and the engineering team was working overnight, and two brand new factory buildings had already been erected. Although the construction site was a bit messy, the project was clearly nearing completion.

The 60 mu of industrial land was acquired by Duan Yun with a foreign exchange earning guarantee. This piece of land is of great significance to Duan Yun.

The new industrial land is divided behind the product technology research and development institute, and it has been connected with the electronics factory. However, as a newly developed land, it is much quieter than some super-large electronics factories, and compared to the electronics factory. The building of the bustling dormitory building, cafeteria and bathroom, here is more like the back garden of a wealthy family, everything looks so deserted.

"Did you see these two newly built factories? Your main task these days is to ensure that the two factories are renovated into dust-free factories." Duan Yun pointed to the two factories in front of him and said to Erhu.

The plug-in machine is a device that has high requirements on the environment. The key components, including the miniature cylinder, the conveyor belt and the ball bearing, must operate in a dust-free environment. If any impurities fall into it, the operation accuracy of the entire machine will decrease. , or even damage downtime.

In fact, Duan Yun wanted to hand over the decoration of the dust-free workshop to Dajun, but the electronics factory at Dajun's side is very busy, while the two tigers at the machinery factory are relatively free, so Duan Yun assigned the dust-free workshop to the factory. Leave the matter to Erhu.

"Clean room?" Erhu froze for a moment when he heard this.

"That's right, the dust-free workshop means that the environmental hygiene requirements of the workshop are very high, and no dust and dirt can be brought in." Duan Yun paused, and then said: "Our country currently only has dust-free workshops in the aerospace sector. The plant needs to install a suspended ceiling, install high-power air conditioners and ventilation fans, and paint the floor. You can discuss the specific plan with the engineering team, which is roughly the case.”

In fact, Duan Yun had visited some dust-free workshops in China in his previous life, but he only had a rough idea of ​​its specific structure.

However, the dust-free workshop requirements for Duan Yun’s installation of plug-in machines are actually not strict, and there is no need to meet the same standards as the dust-free assembly workshop of the aviation department, so it is only necessary to install a suspended ceiling and air-conditioning and ventilation fan equipment, and then paint the floor. Basically, the use environment requirements of the plug-in machine can be met.

"Master, I've never seen a clean room before..." Er Hu said with a look of embarrassment on hearing this.

"Just follow the plan I proposed just now. Install the ceiling, air-conditioning and ventilation fans, and paint the floor. You and the construction team will figure out how to decorate it. Anyway, it must be much cleaner than ordinary factories." Duan Yun said.

"Okay." Erhu nodded.

"I have other things to do, I'll leave it to you here." Duan Yun patted Erhu on the shoulder, then turned around with Peng Changming and came to the research institute.

In the office of the research institute, Duan Yun held a pen and paper and explained to Peng Changming the design principle of the plug-in machine.

The circuit part of the plug-in motor was made by the electronics factory, and Duan Yun, who made the mechanical part, handed it over to Peng Changming.

"...At present, the air pressure of this kind of cylinder is 0.4~0.6MP a, and the gas consumption is about 0.2 cubic/min. It requires strong sealing, no oil leakage, and high control accuracy..." Duan Yun drew on the paper After drawing a simple diagram of the mechanical part of the plug-in machine, he explained it to Peng Changming.

"Did you come up with this part of the mechanical structure?" Peng Changming asked in surprise when he saw the simple structure diagram drawn by Duan Yun.

"The last time I went to Japan, I saw a plug-in machine from a Japanese manufacturer. The internal structure is roughly like this." Duan Yun prevaricated.

"So that's the case, let me just say, it's a god to be able to come up with such a sophisticated mechanical design out of thin air." Peng Changming showed a sudden look, and then said: "Give me your sketch, and write down the technical requirements Go up, I'll redesign it for you again... This plug-in machine is a bit interesting..."

It was also the first time for Peng Changming to come into contact with a plug-in machine. This kind of advanced equipment aroused his great interest, so that he can't wait to start working now.

"The working principle of the plug-in machine plug is like this..." Duan Yun explained to Peng Changming the design principles of some plug-ins and key mechanical equipment, and also added many details and technical requirements.

The performance of the plug-in machines that Duan Yun came into contact with in later generations must be far more advanced than the products in the early 80s, but this is mainly reflected in the digital control and sensing devices, and the principle of the mechanical part is basically the same as that of the products in the 80s. The motor is used as the driving system, the gear transmission and belt transmission, as well as the design of the cylinder and the plug are similar.

"Little Japan's design is really amazing..." Peng Changming said with emotion after seeing Duan Yun explain the design principles and requirements of the plug-in machine in detail.

"Actually, our countrymen are not bad, but we started a little late." Duan Yun smiled, and then said: "Then I will leave the design of the mechanical part of the plug-in motor to you, Professor Peng."

"Don't worry, I'll start designing now." Peng Changming carefully folded the simple diagram drawn by Duan Yun, put it in his pocket, and said to Duan Yun: "By the way, we have overtime work at night in the cafeteria. meal?"

"Must!" Duan Yun replied bluntly, and said, "From today onwards, I will ask the people in the cafeteria to bring you three meals a day plus supper. In addition, what you want to eat, you only need to share with work The staff just say it."

"That's great, I'll go get busy first." Hearing this, Peng Changming got up and was about to leave.

"You can pay attention to your body and don't get tired..." Duan Yun settled down when he saw this.

"Understood." Peng Changming replied casually, and walked out of the office.

One kind of happiness is being able to treat one's hobbies as a job. Peng Changming is like this. His obsession with machinery is far beyond Duan Yun's imagination. Even after officially retiring at the age of sixty, this passion still shows no signs of cooling down. .

Duan Yun originally wanted to set a design deadline for Peng Changming, but now it seems that there is no need to propose a deadline, because Peng Changming will definitely do his best to work, and there is no need for Duan Yun's pressure and encouragement.

Now all the retired professors and technicians in the product technology research and development institute have their own tasks. The next one or two months will be a critical period for Duanyun Enterprise. If all the projects of the institute can be successfully completed on time, then His business plan will take a crucial step...
